Randomized, controlled trial of Interpersonal and Social Rhythm Therapy for young people with bipolar disorder

Co-Occurring Bipolar and Substance Use Disorders: A Review of Impacts, Biopsychosocial Mechanisms, Assessment, and Treatment

Individuals with bipolar disorder are at significant risk for having a co-occurring substance use disorder-particularly, alcohol and cannabis use disorders. Having a co-occurring substance use disorder is associated with a more pernicious clinical course, lower quality of life, and poorer treatment outcomes. Despite its increased morbidity, there is little research and clinical evidence-based guidelines on the treatment of individuals with co-occurring bipolar and substance use disorders. This review details current knowledge on the prevalence, clinical correlates, and biopsychosocial mechanisms underlying co-occurring bipolar and substance use disorders. The authors present recent research that highlights underlying mechanisms of comorbidity, including aberrant reward processing, stress sensitization, early childhood maltreatment, and gene-environment interactions. Next, the authors review current evidence-based recommendations for the assessment and treatment of co-occurring bipolar and substance use disorder, highlighting areas of needed future clinical research.

Chronotherapeutic intervention targeting emotion regulation brain circuitry, symptoms, and suicide risk in adolescents and young adults with bipolar disorder: a pilot randomised trial

BACKGROUND

Mood episodes and high suicide risk of bipolar disorder (BD) are thought to derive from amygdala-ventral prefrontal cortex emotion regulation brain circuitry dysfunction and resulting emotion dysregulation, making these potential intervention targets.

OBJECTIVE

To assess feasibility, acceptability, and preliminary efficacy in engaging the emotion regulation targets of two Brain Emotion Circuitry-targeted Self-Monitoring and Regulation Therapy (BE-SMART) variations in adolescents and young adults with BD (BDAYA): BE-SMART-ER, which directly targets emotion regulation, and BE-SMART-DR, a social rhythm therapy (SRT)-based chronotherapeutic intervention designed to reduce daily rhythm (DR) irregularities.

METHODS

In a single-blind, parallel, pilot-randomised trial, 60 BDAYA (aged 16-29 years) were randomised to 12 weekly sessions (9 telehealth) of BE-SMART-DR or BE-SMART-ER. Nineteen BE-SMART-DR and 16 BE-SMART-ER participants completed the intervention, with 11 and 13, respectively, having pre-intervention and post-intervention functional MRI data.

FINDINGS

In addition to demonstrating feasibility, only BE-SMART-DR showed pre-treatment to post-treatment improvements in DR regularity (Cohen's d=0.55; 95% CI [0.06, 1.03]), associated with reductions in left amygdala responses to emotional face stimuli (p FWE (family-wise error)-SVC (small volume correction)<0.05), difficulties in emotion regulation (d=0.75; 95% CI [0.23, 1.25]) and suicide risk (d=0.65; 95% CI [0.15, 1.14]). Significant correlations were observed among these changes (p<0.05). Both interventions showed high acceptability and improvements in depression and mania symptoms. No intervention-related adverse events were observed.

CONCLUSIONS

Regularising DRs may enhance emotion regulation brain circuitry functioning, emotion regulation, and reduce suicide risk in BDAYA.

CLINICAL IMPLICATIONS

Chronotherapeutic interventions regularising DRs, such as SRT, should be studied further as potential treatment strategies for BDAYA.

The efficacy of InterRhythmic care for depression: A randomized control trial

OBJECTIVE

This study investigates the efficacy of an InterRhythmic Care (IRC) for major depressive disorder (MDD). There is a lack of clinical studies on its effect on depression.

METHODS

In this eight-week, randomized, single-blind, controlled trial, 120 patients with MDD were randomly assigned to receive IRC or Internet general psychoeducation (IGP). Participants' depressive and anxiety symptoms, interpersonal relationships, social function, and biological rhythms were assessed using the 17-item Hamilton Depression Rating Scale (HAMD-17), Hamilton Anxiety Scale (HAMA), Interpersonal Comprehensive Diagnostic Scale (ICDS), Sheehan Disability Scale (SDS), and Morning and Evening Questionnaire (MEQ) at baseline and the 8th week.

RESULTS

Compared to participants in IGP, participants in IRC had lower HAMD total scores, anxiety/somatization, weight, cognitive disturbance, retardation, and sleep disturbance subscores in patients with MDD (F = 190.94, p Bonferroni < 0.001; F = 83.13, p Bonferroni < 0.001; F = 4.15, p Bonferroni = 0.048; F = 65.42, p Bonferroni < 0.001; F = 53.15, p Bonferroni < 0.001; F = 67.76, p Bonferroni < 0.001, respectively); HAMA total score, somatic anxiety subscore, psychogenic anxiety subscore (F = 142.97, p Bonferroni < 0.001; F = 111.06, p Bonferroni < 0.001; F = 128.04, p Bonferroni < 0.001); ICDS total score and subscores for conversation, making friends, manners; and SDS subscores for work/school, social life, family life, and days underproductive (F = 17.38, p Bonferroni <0.001; F = 14.61, p Bonferroni < 0.001; F = 10.97, p Bonferroni = 0.001; F = 11.74, p Bonferroni = 0.001; F = 4.85, p Bonferroni = 0.031; F = 16.29, p Bonferroni < 0.001; F = 12.11, p Bonferroni = 0.001; F = 8.3, p Bonferroni = 0.005) at the end of the intervention period.

CONCLUSIONS

IRC helped patients with MDD improve clinical symptoms, including depressive and anxiety symptoms, interpersonal problems, and social function.

Interpersonal Psychotherapy: A Review of Theory, History, and Evidence of Efficacy

Interpersonal psychotherapy (IPT) is an empirically validated treatment for mood disorders, anxiety disorders, eating disorders, and trauma. IPT is based on the concept of "relational frame"-that an individual's experience of psychological distress impacts those around them, and that their social support network impacts the distressed individual. This concept, along with the specific techniques and tools that flow from it and the theoretical bases of IPT (attachment and interpersonal theory) make IPT unique. In this article we review the theoretical bases of IPT (attachment and communication) and provide a brief history of IPT, as well as the evidence supporting its use for a variety of disorders. We also describe its application to groups, adolescents, and other diverse populations. Future directions for research and treatment development are proposed, particularly research in the area of combining IPT with other psychotherapeutic modalities.

Insights into the Effect of Light Pollution on Mental Health: Focus on Affective Disorders-A Narrative Review

The presence of artificial light at night has emerged as an anthropogenic stressor in recent years. Various sources of light pollution have been shown to affect circadian physiology with serious consequences for metabolic pathways, possibly disrupting pineal melatonin production with multiple adverse health effects. The suppression of melatonin at night may also affect human mental health and contribute to the development or exacerbation of psychiatric disorders in vulnerable individuals. Due to the high burden of circadian disruption in affective disorders, it has been hypothesized that light pollution impacts mental health, mainly affecting mood regulation. Hence, the aim of this review was to critically summarize the evidence on the effects of light pollution on mood symptoms, with a particular focus on the role of circadian rhythms in mediating this relationship. We conducted a narrative review of the literature in the PubMed, Scopus, and Web of Science datasets. After the screening process, eighteen papers were eligible for inclusion. The results clearly indicate a link between light pollution and the development of affective symptoms, with a central role of sleep disturbances in the emergence of mood alterations. Risk perception also represents a crucial topic, possibly modulating the development of affective symptoms in response to light pollution. The results of this review should encourage a multidisciplinary approach to the design of healthier environments, including lighting conditions among the key determinants of human mental health.

Chinese self-report version of biological rhythms interview for assessment in neuropsychiatry (C-BRIAN-SR) - psychometric properties and prospective follow-up in patients with non-seasonal depression

This study examined the psychometric properties and longitudinal changes of the self-reporting Traditional Chinese version of Biological Rhythms Interview for Assessment in Neuropsychiatry (C-BRIAN-SR) among healthy controls (HC) and patients with major depressive episode (MDE). Eighty patients with a current MDE and 80 HC were recruited. Assessments were repeated after two weeks in HC, and upon the discharge of MDE patients to examine the prospective changes upon remission of depression. The C-BRIAN-SR score was significantly higher in the MDE than HC group. The concurrent validity was supported by a positive correlation between scores of C-BRIAN-SR, Insomnia Severity Index and the Hospital Anxiety Depression Scale. C-BRIAN-SR negatively correlated MEQ in the MDE group (r = .30, p = 0.009), suggesting higher rhythm disturbances were associated with a tendency toward eveningness. A moderate test-retest reliability was found (r = .61, p < 0.001). A cut-off of 38.5 distinguished MDE subjects from HC with 82.9% of sensitivity and 81.0% of specificity. C-BRIAN-SR score normalized in remitted MDE patients but remained higher in the non-remitted. The C-BRIAN-SR is a valid and reliable scale for measuring the biological rhythms and may assist in the screening of patients with MDE.

BI-REAL: A 12-session DBT skills group intervention adapted for bipolar disorder - A feasibility randomised pilot trial

International guidelines endorse psychological treatment for Bipolar Disorder (BD); however, the absence of a recognised gold-standard intervention requires further research. A Dialectical Behaviour Therapy (DBT) skills group intervention with 12 sessions was developed. This pilot randomised controlled trial (RCT) aims to evaluate the feasibility, acceptability, and outcomes variance of Bi-REAL - Respond Effectively, Assertively, and Live mindfully, tailored for individuals with BD, in preparation for a future RCT.

METHODS

52 participants (female = 62.7 %; mean age = 43.2 ± 11.1) with BD were randomised by blocks to either the experimental group (EG; n = 26; Bi-REAL + Treatment as Usual, TAU) receiving 12 weekly 90-minutes sessions, or the control group (CG; n = 26, TAU). Feasibility and acceptability were assessed with a multimethod approach (qualitative interviews, semi-structured clinical interviews and a battery of self-report questionnaires - candidate main outcomes Bipolar Recovery Questionnaire (BRQ) and brief Quality of Life for Bipolar Disorder (QoL.BD)). All participants were evaluated at baseline (T0), post-intervention (T1) and 3-month follow-up (T2).

RESULTS

Acceptability was supported by participants' positive feedback and ratings of the sessions and programme overall, as well as the treatment attendance (86.25 % of sessions attended). The trial overall retention rate was 74.5 %, with CG having a higher dropout rate across the 3-timepoints (42.31 %). A significant Time × Group interaction effect was found for BRQ and QoL.BD favouring the intervention group (p < .05).

LIMITATIONS

The assessors were not blind at T1 (only at T2). Recruitment plan was impacted due to COVID-19 restrictions and replication is questionable. High attrition rates in the CG.

CONCLUSIONS

The acceptability of Bi-REAL was sustained, and subsequent feasibility testing will be necessary to establish whether the retention rates of the overall trial improve and if feasibility is confirmed, before progressing to a definitive trial.

Suicide Assessment and Prevention in Bipolar Disorder: How Current Evidence Can Inform Clinical Practice

Bipolar disorder is associated with a considerable risk of suicide, and this fact must be incorporated into management of all patients with the condition. This article highlights the importance of a more nuanced understanding of the factors associated with the increased risk of suicidal behavior in people diagnosed as having bipolar disorder and interventions that could mitigate it. Several sociodemographic, clinical, environmental, and other variables have been associated with suicide attempts or deaths in bipolar disorder. Youths with bipolar disorder are a particularly vulnerable group, and their trajectory of illness could be modified by early interventions. Several medications have been studied regarding their relationship to suicide risk in bipolar disorder, and interventional psychiatry is a newer area of research focus. Finally, community-based approaches can be incorporated into a comprehensive approach to suicide prevention. This article summarizes the current understanding of key variables that can help inform a clinical risk assessment of individuals and interventions that can be employed in suicide prevention in bipolar disorder.

Lifestyle interventions for bipolar disorders: A systematic review and meta-analysis

This review and meta-analysis aimed to describe the existing literature on interventions for bipolar disorder (BD) targeting the 6 pillars of Lifestyle Psychiatry: diet, physical activity (PA), substance use (SU), sleep, stress management, and social relationships (SR). Randomized Controlled Trials that examined the efficacy of lifestyle interventions targeting improvement in depressive/(hypo)manic symptom severity, lifestyle patterns, functioning, quality of life, and/or circadian rhythms were included. The systematic review included 18 studies, while the meta-analysis included studies targeting the same lifestyle domains and outcomes. Sleep (n = 10), PA (n = 9), and diet (n = 8) were the most targeted domains, while SU, SM and SR were least targeted (n = 4 each). Combined diet and PA interventions led to significant improvements in depressive symptoms (SMD: -0.46; 95%CI: -0.88, -0.04; p = 0.03), and functioning (SMD: -0.47; 95%CI: -0.89, -0.05; p = 0.03). Sleep interventions also led to significant improvements in depressive symptoms (SMD: -0.80; 95%CI: -1.21, -0.39; p < 0.01). Future research should focus on developing more multidimensional lifestyle interventions for a potentially greater impact on clinical and functional outcomes of BD.

Boosting the Theory of Mind Network: Specific Psychotherapy Increases Neural Correlates of Affective Theory of Mind in Euthymic Bipolar Disorder

BACKGROUND

In bipolar disorder, impaired affective theory of mind (aToM) performance and aberrant neural activation in the ToM brain network partly explain social functioning impairments. However, it is not yet known whether psychotherapy of bipolar disorder influences neuroimaging markers of aToM.

METHODS

In this study, conducted within the multicentric randomized controlled trial of the BipoLife consortium, patients with euthymic bipolar disorder underwent 2 group interventions over 6 months (mean = 28.45 weeks): 1) a specific, cognitive behavioral intervention (specific psychotherapeutic intervention [SEKT]) (n = 31) targeting impulse regulation, ToM, and social skills and 2) an emotion-focused intervention (FEST) (n = 28). To compare the effect of SEKT and FEST on neural correlates of aToM, patients performed an aToM task during functional magnetic resonance imaging before and after interventions (final functional magnetic resonance imaging sample of pre- and postcompleters, SEKT: n = 16; FEST: n = 17). Healthy control subjects (n = 32) were scanned twice with the same time interval. Because ToM was trained in SEKT, we expected an increased ToM network activation in SEKT relative to FEST postintervention.

RESULTS

Both treatments effectively stabilized patients' euthymic state in terms of affective symptoms, life satisfaction, and global functioning. Confirming our expectations, SEKT patients showed increased neural activation within regions of the ToM network, bilateral temporoparietal junction, posterior cingulate cortex, and precuneus, whereas FEST patients did not.

CONCLUSIONS

The stabilizing effect of SEKT on clinical outcomes went along with increased neural activation of the ToM network, while FEST possibly exerted its positive effect by other, yet unexplored routes.

A systematic review of interventions in the early course of bipolar disorder I or II: a report of the International Society for Bipolar Disorders Taskforce on early intervention

BACKGROUND

Given the likelihood of progressive illness in bipolar disorder (BD), it is important to understand the benefits and risks of interventions administered early in illness course. We conducted a systematic review of the effectiveness of interventions in the early course of BD I or II.

METHODS

We completed a systematic search on MEDLINE, PsycINFO, EMBASE, the Cochrane Central Register of Controlled Trials, CINAHL and Google Scholar from 1/1/1979 till 14/9/2022. We included controlled trials examining intervention effects on symptomatic, course, functional and tolerability outcomes of patients in the 'early course' of BD I or II. We classified patients to be in early course if they (a) were seeking help for the first time for a manic episode, (b) had a lifetime history of up to 3 manic episodes, or (c) had up to 6 lifetime mood episodes. Evidence quality was assessed using the GRADE approach.

RESULTS

From 4135 unique publications we included 25 reports representing 2212 participants in 16 randomized studies, and 17,714 participants from nine non-randomized studies. Available evidence suggested that in early illness course, lithium use was associated with lower recurrence risk compared with other mood stabilizers. Mood stabilizers were also associated with better global functioning, compared with the use of antipsychotics in the medium term. While summative findings regarding psychological therapies were limited by heterogeneity, family-focused and cognitive-behavioral interventions were associated with reduced recurrence risk or improved symptomatic outcomes. There was some evidence that the same pharmacological interventions were more efficacious in preventing recurrences when utilized in earlier rather than later illness course.

CONCLUSIONS AND RECOMMENDATIONS

While there are promising initial findings, there is a need for more adequately powered trials to examine the efficacy and tolerability of interventions in youth and adults in early illness course. Specifically, there is a compelling need to compare the relative benefits of lithium with other pharmacological agents in preventing recurrences. In addition to symptomatic outcomes, there should be a greater focus on functional impact and tolerability. Effective pharmacological and psychological interventions should be offered to those in early course of BD, balancing potential risks using shared decision-making approaches.

Everyday life experiences for evaluating post-traumatic stress disorder symptoms

Background: Previous research has highlighted the importance of regularizing daily routines for maintaining mental health. Little is known about whether and how regularity of daily routines is associated with reduced post-traumatic stress disorder (PTSD) symptoms.Objective: We aimed to examine the associations between regularity of daily routines and PTSD symptoms in two studies (N = 796).Method: In Study 1, prospective data were analysed with the latent change score model to investigate the association between sustainment of regular daily routines and change in PTSD symptoms over time amid massive civil unrest in Hong Kong in 2019. Study 2 used vignette as a quasi-experimental method to assess the ability of maintaining regular daily routines in face of a major stressor, and tested its associations with PTSD symptoms.Results: In Study 1, increased regularity of diverse daily routines was inversely associated with increased PTSD symptoms amid the civil unrest in Hong Kong (β = -.427 to -.224, 95% confidence intervals [-.543 to -.359, -.310 to -.090], p values < .01). In Study 2, a greater ability to maintain regular daily routines during stress was associated with lower levels of PTSD symptoms (β = -.285 to -.096, 95% confidence intervals [-.379 to -.189, -.190 to -.003], p values < .05).Conclusions: Our findings suggest the benefit of considering diverse everyday activities in evaluating PTSD symptoms in both clinical and subclinical populations. Interventions with the direct focus on the role of daily living could promote psychological resilience during and after potentially traumatic events.

Validation of the Longitudinal Interval Follow-Up Evaluation for the Long-Term Measurement of Mood Symptoms in Bipolar Disorder

The long-term burden of symptoms is an important outcome in bipolar disorder (BD). A method which has minimal burden of assessment uses a retrospective interview, the Longitudinal Interval Follow-up Examination (LIFE), although this may be subject to problems with recall. This study examines the relationship between the retrospective LIFE scale and concurrently-rated mood rating scales in two clinical trials of 18 months of psychotherapy for patients with BD. The Montgomery-Asberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS) were administered every eight to nine weeks and the LIFE was carried out every 6 months. Correlations between scores on mood rating scales and at equivalent times on the LIFE were examined, as well as of potential clinical moderators. There were significant correlations between LIFE depression ratings and concurrent MADRS score (r = 0.57) and between LIFE mania ratings and YMRS score (r = 0.40). In determining "mild depression" on the MADRS, a receiver operating characteristics (ROC) analysis showed an AUC of 0.78 for LIFE scores. Correlations, particularly for depression scores, were high even when the LIFE rating was several months before the interview, suggesting that the LIFE has validity in examining the burden of mood symptoms over time, with relatively little burden of assessment. Future research should examine the relationship between symptom burden and quality of life measured in this way.

Relationship between baseline cognition and 18-month treatment response in bipolar disorder

BACKGROUND

To date, few studies have examined baseline cognitive function as a predictor of clinical outcome following treatment in bipolar disorder (BD). The aim of this analysis was therefore to examine the relationship between baseline cognitive function and treatment outcome in a sample of young adults with BD receiving Interpersonal Social Rhythm Therapy (IPSRT) or Specialist Supportive Care (SSC) with adjunctive pharmacotherapy.

METHODS

Eighty-six BD patients underwent baseline cognitive testing and completed 18 months of IPSRT or SCC. Univariate analyses examined the relationship between baseline cognitive function (global and individual cognitive domains) and change in mood symptom burden, and psychosocial functioning, from baseline to treatment-end.

RESULTS

Baseline global cognition was not predictive of change in mood symptom burden over 18 months of treatment. However, poorer baseline psychomotor speed performance was associated with less improvement in mood symptom burden at treatment-end. Neither baseline global cognition nor individual cognitive domain scores were associated with change in psychosocial functioning.

LIMITATIONS

Due to the exploratory nature of the study, correction was not made for multiple comparisons. Data was obtained from a relatively small sample and has been the subject of prior analysis, thereby increasing the likelihood of chance findings.

CONCLUSION

Although global cognition was not associated with outcome, when examining individual domains, poorer baseline psychomotor speed predicted less change in mood symptom burden following 18-months of psychotherapy and pharmacotherapy. This suggests that pre-treatment measures of psychomotor speed may help to identify those who require additional, and more targeted, intervention. Further large-scale research is required.

Personalized digital intervention for depression based on social rhythm principles adds significantly to outpatient treatment

We conducted a 16-week randomized controlled trial in psychiatric outpatients with a lifetime diagnosis of a mood and/or anxiety disorder to measure the impact of a first-of-its-kind precision digital intervention software solution based on social rhythm regulation principles. The full intent-to-treat (ITT) sample consisted of 133 individuals, aged 18-65. An exploratory sub-sample of interest was those individuals who presented with moderately severe to severe depression at study entry (baseline PHQ-8 score ≥15; N = 28). Cue is a novel digital intervention platform that capitalizes on the smartphone's ability to continuously monitor depression-relevant behavior patterns and use each patient's behavioral data to provide timely, personalized "micro-interventions," making this the first example of a precision digital intervention of which we are aware. Participants were randomly allocated to receive Cue plus care-as-usual or digital monitoring only plus care as usual. Within the full study and depressed-at-entry samples, we fit a mixed effects model to test for group differences in the slope of depressive symptoms over 16 weeks. To account for the non-linear trajectory with more flexibility, we also fit a mixed effects model considering week as a categorical variable and used the resulting estimates to test the group difference in PHQ change from baseline to 16 weeks. In the full sample, the group difference in the slope of PHQ-8 was negligible (Cohen's d = -0.10); however, the Cue group demonstrated significantly greater improvement from baseline to 16 weeks (p = 0.040). In the depressed-at-entry sample, we found evidence for benefit of Cue. The group difference in the slope of PHQ-8 (Cohen's d = -0.72) indicated a meaningfully more rapid rate of improvement in the intervention group than in the control group. The Cue group also demonstrated significantly greater improvement in PHQ-8 from baseline to 16 weeks (p = 0.009). We are encouraged by the size of the intervention effect in those who were acutely ill at baseline, and by the finding that across all participants, 80% of whom were receiving pharmacotherapy, we observed significant benefit of Cue at 16 weeks of treatment. These findings suggest that a social rhythm-focused digital intervention platform may represent a useful and accessible adjunct to antidepressant treatment (https://clinicaltrials.gov/ct2/show/NCT03152864?term=ellen+frank&draw=2&rank=3).

Temporal relationships of ecological momentary mood and actigraphy-based sleep measures in bipolar disorder

Sleep disturbances are a key feature of bipolar disorder (BD), and poor sleep has been linked to mood symptoms. Recent use of ecological momentary assessment (EMA) has allowed for nuanced exploration of the sleep-mood link; though, the scale and directionality of this relationship is still unclear. Using EMA, actigraphy, and self-reported sleep measures, this study examines the concurrent and predictive relationships between sleep and mood. Participants with BD (n = 56) wore actigraphy devices for up to 14 days and completed validated scales and daily EMA surveys about mood and sleep quality. Linear mixed models were used to examine overall and time-lagged relationships between sleep and mood variables. EMA mood ratings were correlated with validated rating scales for depression, mania, anxiety, and impulsivity. Poor self-reported sleep quality was associated with worse overall ratings of sadness and anger. Worse self-reported sleep quality was associated with greater sadness the following day. Higher daytime impulsivity was associated with worse sleep quality the following night. Exploratory analyses found relationships between worse and more variable mood (sadness, anger, and impulsivity) with worse and more variable sleep that evening (efficiency, WASO, and sleep onset time). The sample size was modest, fairly homogenous, and included mainly euthymic persons with BD. EMA-based assessments of mood and sleep are correlated with validated scale scores and provide novel insight into intra-individual variability. Further work on the complex two-way interactions between sleep and mood is needed to better understand how to improve outcomes in BD.

Domain-Based Functional Improvements in Bipolar Disorder After Interpersonal and Social Rhythm Therapy

BACKGROUND

Studies typically report overall change in function when assessing bipolar disorder (BD) interventions, but individual domains are not analyzed. Which aspects of functioning are impacted is clearly important and may differ between treatments.

METHODS

Data were analyzed from two previous clinical trials of Interpersonal and Social Rhythm Therapy (IPSRT) for BD patients. Change in total and subscale scores on the Social Adjustment Scale Self-Report (SAS-SR) from 0 to 78 weeks, were analyzed.

RESULTS

152 BD patients took part in randomized controlled trials of IPSRT (n = 38) vs. Specialist Supportive Care (SSC) (n = 43), and of IPSRT (n = 41) vs. treatment as usual (TAU) which was discharge to primary care (n = 30). IPSRT was superior to TAU on change in the social and leisure activities and extended family subscales, and SAS-SR total score over 18 months.

LIMITATIONS

Studies were not designed to be pooled. Patients in study 1 were younger and symptomatic at baseline. Patients assigned to TAU were more likely to drop-out. Patients did not respond to subscales that were not personally applicable (work, marital, children).

CONCLUSION

IPSRT had a positive impact on two SAS-SR subscales compared to TAU over 18 months. Other subscales were limited by the lack of respondents due to individual applicability. Different psychotherapy may have differential effects on different domains of function. Measures of function and research into functioning in BD should include domain-based measures, and report the numbers of participants who respond to questions in each domain.

Telehealth Social Rhythm Therapy to Reduce Mood Symptoms and Suicide Risk Among Adolescents and Young Adults With Bipolar Disorder

OBJECTIVE

Social rhythm irregularities are associated with increased bipolar disorder symptoms and suicide risk. This study was the first to examine the feasibility and acceptability of a 12-week social rhythm therapy (SRT) delivered predominantly via telehealth (three in-person sessions, nine via video teleconferencing) to adolescents and young adults with bipolar disorder. The primary aim was to determine the feasibility and acceptability of SRT delivered predominantly via telehealth. Secondary aims were to explore the intervention's impacts on social rhythm regularity, mood symptoms, and suicide propensity.

METHODS

Thirteen adolescents and young adults with bipolar disorder received a modified SRT called Brain Emotion circuitry-targeted Self-Monitoring And Regulation Therapy for Daily Rhythms (BE-SMART-DR) administered mostly remotely, adjunctive to treatment as usual. Retention rates, client satisfaction, therapeutic alliance, and pre- to postintervention changes in social rhythm regularity, mood symptoms, and suicide propensity were assessed.

RESULTS

BE-SMART-DR was associated with high retention rates (77%), high mean±SD scores on the Client Satisfaction Questionnaire (29.4±2.7), and high participant global scores on the Working Alliance Inventory (231.3±8.1), indicative of strong therapeutic alliance. Secondary outcome measures on social rhythm irregularities, mood symptoms, and suicide propensity decreased from pre- to posttherapy. Increased social rhythm regularity was associated with reduced suicide propensity after analyses were controlled for reductions in mood symptoms.

CONCLUSIONS

These preliminary results indicate that SRT delivered largely by telemedicine is feasible and acceptable. The intervention appeared to reduce mood symptoms, and suicide propensity independent of mood symptoms, among adolescents and young adults with bipolar disorder.

Novel insights into irritability: the relationship between subjective experience, age and mood

BACKGROUND

The relationship between irritability as a subjective experience and the behavioural indicators typically used to measure the construct are not known. Its links to mood, and contextual relationships, vary with age and are yet to be thoroughly examined.

AIMS

First, to interrogate the relationship between the subjective experience of irritability and mood, and that with its behavioural indicators. Second, to determine how these relationships vary with age and over time.

METHOD

This study examined data from a previous clinical trial of adolescents and young adults (N = 82) with bipolar disorder, who received a psychological intervention over 18 months. Participants completed a battery of questionnaires, which included assessments of irritability. Analyses of covariance were conducted to examine the interaction between mood symptoms, subjective measures of irritability, behavioural measures of irritability and age over time.

RESULTS

Subjective irritability scores differed significantly over time when controlling for manic, but not depressive, symptom scores. Further, subjective irritability significantly differed when controlling for behavioural measures of irritability (temper outbursts and argumentativeness). There were significant interactions between scores of depressive symptoms, temper outbursts and subjective irritability with age, wherein younger participants showed no correlation between depressive symptoms and temper outbursts. In addition, younger participants showed lower correlations between subjective irritability and both depressive and temper outburst scores, than older participants.

CONCLUSIONS

Subjective irritability is linked to mood morbidity and behavioural outbursts, and these relationships are contingent on age. Our novel findings suggest that subjective irritability should be assessed in greater detail in patients with mood disorders.

Psychosocial interventions for self-harm in adults

BACKGROUND

Self-harm (SH; intentional self-poisoning or self-injury regardless of degree of suicidal intent or other types of motivation) is a growing problem in most counties, often repeated, and associated with suicide. There has been a substantial increase in both the number of trials and therapeutic approaches of psychosocial interventions for SH in adults. This review therefore updates a previous Cochrane Review (last published in 2016) on the role of psychosocial interventions in the treatment of SH in adults.

OBJECTIVES

To assess the effects of psychosocial interventions for self-harm (SH) compared to comparison types of care (e.g. treatment-as-usual, routine psychiatric care, enhanced usual care, active comparator) for adults (aged 18 years or older) who engage in SH.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Specialised Register, the Cochrane Library (Central Register of Controlled Trials [CENTRAL] and Cochrane Database of Systematic reviews [CDSR]), together with MEDLINE, Ovid Embase, and PsycINFO (to 4 July 2020).

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) comparing interventions of specific psychosocial treatments versus treatment-as-usual (TAU), routine psychiatric care, enhanced usual care (EUC), active comparator, or a combination of these, in the treatment of adults with a recent (within six months of trial entry) episode of SH resulting in presentation to hospital or clinical services. The primary outcome was the occurrence of a repeated episode of SH over a maximum follow-up period of two years. Secondary outcomes included treatment adherence, depression, hopelessness, general functioning, social functioning, suicidal ideation, and suicide.

DATA COLLECTION AND ANALYSIS

We independently selected trials, extracted data, and appraised trial quality. For binary outcomes, we calculated odds ratio (ORs) and their 95% confidence intervals (CIs). For continuous outcomes, we calculated mean differences (MDs) or standardised mean differences (SMDs) and 95% CIs. The overall quality of evidence for the primary outcome (i.e. repetition of SH at post-intervention) was appraised for each intervention using the GRADE approach.

MAIN RESULTS

We included data from 76 trials with a total of 21,414 participants. Participants in these trials were predominately female (61.9%) with a mean age of 31.8 years (standard deviation [SD] 11.7 years). On the basis of data from four trials, individual cognitive behavioural therapy (CBT)-based psychotherapy may reduce repetition of SH as compared to TAU or another comparator by the end of the intervention (OR 0.35, 95% CI 0.12 to 1.02; N = 238; k = 4; GRADE: low certainty evidence), although there was imprecision in the effect estimate. At longer follow-up time points (e.g., 6- and 12-months) there was some evidence that individual CBT-based psychotherapy may reduce SH repetition. Whilst there may be a slightly lower rate of SH repetition for dialectical behaviour therapy (DBT) (66.0%) as compared to TAU or alternative psychotherapy (68.2%), the evidence remains uncertain as to whether DBT reduces absolute repetition of SH by the post-intervention assessment. On the basis of data from a single trial, mentalisation-based therapy (MBT) reduces repetition of SH and frequency of SH by the post-intervention assessment (OR 0.35, 95% CI 0.17 to 0.73; N = 134; k = 1; GRADE: high-certainty evidence). A group-based emotion-regulation psychotherapy may also reduce repetition of SH by the post-intervention assessment based on evidence from two trials by the same author group (OR 0.34, 95% CI 0.13 to 0.88; N = 83; k = 2; moderate-certainty evidence). There is probably little to no effect for different variants of DBT on absolute repetition of SH, including DBT group-based skills training, DBT individual skills training, or an experimental form of DBT in which participants were given significantly longer cognitive exposure to stressful events. The evidence remains uncertain as to whether provision of information and support, based on the Suicide Trends in At-Risk Territories (START) and the SUicide-PREvention Multisite Intervention Study on Suicidal behaviors (SUPRE-MISS) models, have any effect on repetition of SH by the post-intervention assessment. There was no evidence of a difference for psychodynamic psychotherapy, case management, general practitioner (GP) management, remote contact interventions, and other multimodal interventions, or a variety of brief emergency department-based interventions.

AUTHORS' CONCLUSIONS

Overall, there were significant methodological limitations across the trials included in this review. Given the moderate or very low quality of the available evidence, there is only uncertain evidence regarding a number of psychosocial interventions for adults who engage in SH. Psychosocial therapy based on CBT approaches may result in fewer individuals repeating SH at longer follow-up time points, although no such effect was found at the post-intervention assessment and the quality of evidence, according to the GRADE criteria, was low. Given findings in single trials, or trials by the same author group, both MBT and group-based emotion regulation therapy should be further developed and evaluated in adults. DBT may also lead to a reduction in frequency of SH. Other interventions were mostly evaluated in single trials of moderate to very low quality such that the evidence relating to the use of these interventions is inconclusive at present.

Effects of psychotherapy on comorbid bipolar disorder and substance use disorder: A systematic review

OBJECTIVES

This review aim was to examine whether psychotherapy is more or less effective in patients with SUD, compared to those without; whether there is a differential effect of a particular psychotherapy in patients with SUD.

METHODS

A quantitative systematic review following the Cochrane Handbook of Systematic Reviews was used.

RESULTS

Five studies of psychotherapy for BD and two studies of an integrated psychotherapy for comorbid BD and SUD were included in the review. Five studies provided a sub-analysis of the effect of SUD on overall outcomes with only one finding an overall detrimental effect. The results indicated equal, if not better outcomes for individuals with comorbid BD and SUD.

CONCLUSION

There was little evidence that interventions targeted at both BD and SUD may be more efficacious. Further research in to psychotherapeutic treatment for BD should include individuals with comorbid SUD, and analyse substance use as an outcome. Additionally, research into treatments specifically developed for these commonly comorbid disorders is indicated.

Brief Research Report: A Pilot Study of Cognitive Behavioral Regulation Therapy (CBT-REG) for Young People at High Risk of Early Transition to Bipolar Disorders

Attempts to increase early identification of individuals in the early stages of bipolar disorders (i.e., individuals at high risk of bipolar disorders and/or experiencing a subthreshold syndrome with bipolar symptoms) have highlighted the need to develop high benefit-low risk interventions. We suggest that any new psychological therapy should (i) be acceptable to young people seeking help for the first time, (ii) be applicable to "at risk" conditions and sub-syndromal states and (iii) consider pluripotent factors that may be linked to illness progression not only for bipolar disorders specifically but also for other potential disease trajectories. However, evidence indicates that current interventions for youth with emerging mood disorders mainly represent approaches abbreviated from "disorder-specific" therapies used with older adults and are primarily offered to first episode cases of bipolar disorders who are also receiving psychotropic medication. This brief report discusses empirical findings used to construct core targets for therapeutic interventions that might reduce or delay transition to full-threshold bipolar disorders. We describe an intervention that includes strategies for problem-solving, reducing sleep-wake cycle disturbances, self-management of rumination and that addresses the needs of individuals with "sub-threshold" presentations who are probably at risk of developing a bipolar or other major mental disorders. Outcome data from a case series of 14 youth indicates that the intervention appears to demonstrate a relatively high benefit-to-risk ratio, promising levels of engagement with the therapy modules, and the therapy appears to be acceptable to a wide range of help-seeking youth with early expressions of bipolar psychopathology.

Chronobiology and Chronotherapy in Depression: Current Knowledge and Chronotherapeutic Promises

Background:

Depression is a heavily prevalent mental disorder. Symptoms of depression extend beyond mood, cognition, and behavior to include a spectrum of somatic manifestations in all organic systems. Changes in sleep and neuroendocrine rhythms are especially prominent, and disruptions of circadian rhythms have been closely related to the neurobiology of depression. With the advent of increased research in chronobiology, various pathophysiologic mechanisms have been proposed, including anomalies of sleep architecture, the effects of clock gene polymorphisms in monoamine metabolism, and the deleterious impact of social zeitgebers. The identification of these chronodisruptions has propelled the emergence of several chronotherapeutic strategies, both pharmacological and non-pharmacological, with varying degrees of clinical evidence.

Methods:

The fundamental objective of this review is to integrate current knowledge about the role of chronobiology and depression and to summarize the interventions developed to resynchronize biorhythms both within an individual and with geophysical time.

Results:

We have found that among the non-pharmacological alternatives, triple chronotherapywhich encompasses bright light therapy, sleep deprivation therapy, and consecutive sleep phase advance therapy-has garnered the most considerable scientific interest. On the other hand, agomelatine appears to be the most promising pharmacological option, given its unique melatonergic pharmacodynamics.

Conclusions:

Research in chronotherapy as a treatment for depression is currently booming. Novel interventions could play a significant role in adopting new options for the treatment of depression, with Tripe Cronotherapy standing out as the most promising treatment.

Functional and Mood Outcomes in Bipolar Disorder Patients With and Without Substance Use Disorders Undergoing Psychotherapy

Objectives: Research suggests that patients with co-morbid bipolar disorder (BD) and substance use disorder (SUD) have a poorer illness course and clinical outcome. The evidence is limited as SUD patients are often excluded from BD studies. In particular, evidence regarding long term outcomes from studies using psychotherapies as an adjunctive treatment is limited. We therefore examined data from two studies of Interpersonal Social Rhythm Therapy (IPSRT) for BD to determine whether lifetime or current SUD affected outcomes. Methods: Data were analyzed from two previous clinical trials of IPSRT for BD patients. Change in scores on the Social Adjustment Scale (SAS) from 0 to 78 weeks and cumulative mood scores from 0 to 78 weeks, measured using the Life Interval Follow-Up Evaluation (LIFE), were analyzed. Results: Of 122 patients (non-SUD n = 67, lifetime SUD but no current n = 43, current SUD n = 12), 79 received IPSRT and 43 received a comparison therapy-specialist supportive care-over 18 months. Lifetime SUD had a significant negative effect on change in SAS score but not LIFE score. There was no effect of current SUD on either change in score. Secondary analysis showed no correlation between symptom count and change in SAS total score or LIFE score. Conclusion: Current SUD has no impact on mood or functional outcomes, however, current SUD numbers were small, limiting conclusions. Lifetime SUD appears to be associated with impaired functional outcomes from psychotherapy. There is limited research on co-morbid BD and SUD patients undergoing psychotherapy.

Enhancing Dialectical Behavior Therapy for the Treatment of Bipolar Disorder

Dialectical behavior therapy (DBT) is a third wave, behavioral therapy that is designed to target emotion dysregulation. The current study investigated whether DBT could be an effective treatment intervention for bipolar disorder and how it could be adapted for this population. Although empirical study of DBT and bipolar disorder is limited, there is evidence to suggest that DBT is a promising treatment for bipolar disorder. In this study, adapted DBT products were created for bipolar disorder, and feedback on the products was elicited from five experts in the field through semi-structured interviews. Interviews were transcribed and coded for analyses. The findings from the interviews were integrated into revised products with the intention to be used in the clinical community. Several experts reported currently using DBT for bipolar disorder treatment. We conclude that a form of DBT using adapted materials could be a promising intervention for the treatment of bipolar disorder, although more research is needed to demonstrate efficacy. Future directions include conducting randomized controlled trials on DBT and bipolar disorder, as well as testing the created product in clinical practice.

Clinical Effectiveness Trial of Adjunctive Interpersonal and Social Rhythm Therapy for Patients With Bipolar Disorder

OBJECTIVE

This study compared relapse rates at 18 months among patients with bipolar disorder who, after discharge from publicly funded mental health services, received either adjunctive interpersonal and social rhythm therapy (IPSRT) or treatment as usual (general practice medical care).

METHODS

Patients diagnosed as having a bipolar I or II disorder who had been discharged from publicly funded mental health services in New Zealand during the previous 3 months were randomly assigned to 18 months of IPSRT or to treatment as usual. The primary outcome measure was the Life Interval Follow-Up Evaluation (LIFE) completed at weeks 26, 52, and 78 of treatment. Secondary measures were scores on the Social Adjustment Scale (SAS) and the Quality of Life-Bipolar Disorder Scale (QoL-BD) and readmission to mental health services.

RESULTS

The sample consisted of 88 patients. In this intention-to-treat analysis, no significant differences were observed in rates of mood episodes between the groups (odds ratio=0.93, 95% confidence interval=0.37-2.17, p=0.86). A statistically significant difference was seen between the intervention and treatment-as-usual groups in scores on the SAS (effect size=0.5) but not on the QoL-BD. A significantly lower readmission rate was observed among the intervention group.

CONCLUSIONS

This pragmatic clinical effectiveness trial found that a combination of IPSRT and medication management over 18 months did not significantly improve mood relapse but did improve patient functioning.

Interpersonal Psychotherapy: A Scoping Review and Historical Perspective (1974-2017)

BACKGROUND

Interpersonal Psychotherapy (IPT) is an affect- and relationally focused, time-limited treatment supported by research spanning >4 decades. IPT focuses on stressful interpersonal experiences of loss, life changes, disputes, and social isolation. It emphasizes the role of relationships in recovery. This scoping review describes, within a historical perspective, IPT's evolution as an evidence-supported treatment of psychiatric disorders.

METHODS

English-language publications (n = 1119) identified via EMBASE, MEDLINE, PsycINFO, and Web of Science databases (1974-2017), augmented with manual reference searches, were coded for clinical focus, population demographics, format, setting, publication type, and research type. Quantitative and qualitative analyses identified IPT publications' characteristics and trends over four epochs of psychotherapy research.

RESULTS

IPT literature primarily focused on depression (n = 772 articles; 69%), eating disorders (n = 135; 12%), anxiety disorders (n = 68; 6%), and bipolar disorder (n = 44; 4%), with rising publication rates and numbers of well-conducted randomized, controlled trials over time, justifying inclusion in consensus treatment guidelines. Research trends shifted from efficacy trials to effectiveness studies and population-based dissemination initiatives. Process research examined correlates of improvement and efficacy moderators. Innovations included global initiatives, prevention trials, and digital, web-based training and treatment.

CONCLUSION

Sparked by clinical innovations and scientific advances, IPT has evolved as an effective treatment of psychiatric disorders across the lifespan for diverse patients, including underserved clinical populations. Future research to elucidate mechanisms of change, improve access, and adapt to changing frameworks of psychopathology and treatment planning is needed. IPT addresses the universal centrality of relationships to mental health, which is as relevant today as it was over 40 years ago.

Social rhythm therapy-A potentially translatable psychosocial intervention for bipolar disorder

INTRODUCTION

The aim of this paper was to present Social Rhythm Therapy, which has been modified from Interpersonal and Social Rhythm Therapy, by drawing on implementation science to describe a process that for integrating this into routine clinical practice.

METHOD

On the basis of the principles of user-centred design, we aimed to modify an existing psychosocial therapy for bipolar disorder to make this readily translatable into a range of clinical practice models which could be further modified based on feedback from end users.

RESULTS

Social Rhythm Therapy has been adapted from Interpersonal and Social Rhythm Therapy which has demonstrated efficacy in research settings. The adaptation was developed in order to facilitate implementation of some of the key components in routine clinical practice. It is short, relatively simple, easily learned and intended to be flexible.

CONCLUSIONS

Social rhythm therapy for bipolar disorder has many characteristics which may make it translatable into clinical practice in different settings. There is a need for studies into the clinical effectiveness of this intervention that has been modified from an evidence-based intervention.

Improvement in cognitive function in young people with bipolar disorder: Results from participants in an 18-month randomised controlled trial of adjunctive psychotherapy

OBJECTIVE

To examine the effects of 18 months of intensive stabilisation with medication management and Interpersonal and Social Rhythm Therapy or Non-specific Supportive Clinical Management on cognitive function in young people with bipolar disorder. Determinants of change in cognitive function over the 18 months of the trial were also examined.

METHOD

Patients aged 15-36 years with Bipolar I Disorder, Bipolar II Disorder and Bipolar Not Otherwise Specified were recruited. From a battery of cognitive tests, change scores for pre-defined domains of cognitive function were created based on performance at baseline and follow-up. Change was compared between the two therapy groups. Regression analysis was used to determine the impact of a range of clinical variables on change in cognitive performance between baseline and follow-up.

RESULTS

One hundred participants were randomised to Interpersonal and Social Rhythm Therapy (n = 49) or Non-specific Supportive Clinical Management (n = 51). Seventy-eight patients underwent cognitive testing at baseline and 18 months. Across both groups, there were significant improvements in a Global Cognitive Composite score, Executive Function and Psychomotor Speed domains from baseline to 18 months. Lower scores at baseline on all domains were associated with greater improvement over 18 months. Overall, there was no difference between therapies in change in cognitive function, either in a global composite score or change in domains.

CONCLUSION

While there was no difference between therapy groups, intensive stabilisation with psychological therapy was associated with improved cognitive function, particularly in those patients with poorer cognitive function at baseline. However, this was not compared with treatment as usual so cannot be attributed necessarily to the therapies.

Right care, first time: a highly personalised and measurement-based care model to manage youth mental health

Mood and psychotic syndromes most often emerge during adolescence and young adulthood, a period characterised by major physical and social change. Consequently, the effects of adolescent-onset mood and psychotic syndromes can have long term consequences. A key clinical challenge for youth mental health is to develop and test new systems that align with current evidence for comorbid presentations and underlying neurobiology, and are useful for predicting outcomes and guiding decisions regarding the provision of appropriate and effective care. Our highly personalised and measurement-based care model includes three core concepts: ▶ A multidimensional assessment and outcomes framework that includes: social and occupational function; self-harm, suicidal thoughts and behaviour; alcohol or other substance misuse; physical health; and illness trajectory. ▶ Clinical stage. ▶ Three common illness subtypes (psychosis, anxious depression, bipolar spectrum) based on proposed pathophysiological mechanisms (neurodevelopmental, hyperarousal, circadian). The model explicitly aims to prevent progression to more complex and severe forms of illness and is better aligned to contemporary models of the patterns of emergence of psychopathology. Inherent within this highly personalised approach is the incorporation of other evidence-based processes, including real-time measurement-based care as well as utilisation of multidisciplinary teams of health professionals. Data-driven local system modelling and personalised health information technologies provide crucial infrastructure support to these processes for better access to, and higher quality, mental health care for young people. CHAPTER 1: MULTIDIMENSIONAL OUTCOMES IN YOUTH MENTAL HEALTH CARE: WHAT MATTERS AND WHY?: Mood and psychotic syndromes present one of the most serious public health challenges that we face in the 21st century. Factors including prevalence, age of onset, and chronicity contribute to substantial burden and secondary risks such as alcohol or other substance misuse. Mood and psychotic syndromes most often emerge during adolescence and young adulthood, a period characterised by major physical and social change; thus, effects can have long term consequences. We propose five key domains which make up a multidimensional outcomes framework that aims to address the specific needs of young people presenting to health services with emerging mental illness. These include social and occupational function; self-harm, suicidal thoughts and behaviours; alcohol or other substance misuse; physical health; and illness type, stage and trajectory. Impairment and concurrent morbidity are well established in young people by the time they present for mental health care. Despite this, services and health professionals tend to focus on only one aspect of the presentation - illness type, stage and trajectory - and are often at odds with the preferences of young people and their families. There is a need to address the disconnect between mental health, physical health and social services and interventions, to ensure that youth mental health care focuses on the outcomes that matter to young people. CHAPTER 2: COMBINING CLINICAL STAGE AND PATHOPHYSIOLOGICAL MECHANISMS TO UNDERSTAND ILLNESS TRAJECTORIES IN YOUNG PEOPLE WITH EMERGING MOOD AND PSYCHOTIC SYNDROMES: Traditional diagnostic classification systems for mental disorders map poorly onto the early stages of illness experienced by young people, and purport categorical distinctions that are not readily supported by research into genetic, environmental and neurobiological risk factors. Consequently, a key clinical challenge in youth mental health is to develop and test new classification systems that align with current evidence on comorbid presentations, are consistent with current understanding of underlying neurobiology, and provide utility for predicting outcomes and guiding decisions regarding the provision of appropriate and effective care. This chapter outlines a transdiagnostic framework for classifying common adolescent-onset mood and psychotic syndromes, combining two independent but complementary dimensions: clinical staging, and three proposed pathophysiological mechanisms. Clinical staging reflects the progression of mental disorders and is in line with the concept used in general medicine, where more advanced stages are associated with a poorer prognosis and a need for more intensive interventions with a higher risk-to-benefit ratio. The three proposed pathophysiological mechanisms are neurodevelopmental abnormalities, hyperarousal and circadian dysfunction, which, over time, have illness trajectories (or pathways) to psychosis, anxious depression and bipolar spectrum disorders, respectively. The transdiagnostic framework has been evaluated in young people presenting to youth mental health clinics of the University of Sydney's Brain and Mind Centre, alongside a range of clinical and objective measures. Our research to date provides support for this framework, and we are now exploring its application to the development of more personalised models of care. CHAPTER 3: A COMPREHENSIVE ASSESSMENT FRAMEWORK FOR YOUTH MENTAL HEALTH: GUIDING HIGHLY PERSONALISED AND MEASUREMENT-BASED CARE USING MULTIDIMENSIONAL AND OBJECTIVE MEASURES: There is an urgent need for improved care for young people with mental health problems, in particular those with subthreshold mental disorders that are not sufficiently severe to meet traditional diagnostic criteria. New comprehensive assessment frameworks are needed to capture the biopsychosocial profile of a young person to drive highly personalised and measurement-based mental health care. We present a range of multidimensional measures involving five key domains: social and occupational function; self-harm, suicidal thoughts and behaviours; alcohol or other substance misuse; physical health; and illness type, stage and trajectory. Objective measures include: neuropsychological function; sleep-wake behaviours and circadian rhythms; metabolic and immune markers; and brain structure and function. The recommended multidimensional measures facilitate the development of a comprehensive clinical picture. The objective measures help to further develop informative and novel insights into underlying pathophysiological mechanisms and illness trajectories to guide personalised care plans. A panel of specific multidimensional and objective measures are recommended as standard clinical practice, while others are recommended secondarily to provide deeper insights with the aim of revealing alternative clinical paths for targeted interventions and treatments matched to the clinical stage and proposed pathophysiological mechanisms of the young person. CHAPTER 4: PERSONALISING CARE OPTIONS IN YOUTH MENTAL HEALTH: USING MULTIDIMENSIONAL ASSESSMENT, CLINICAL STAGE, PATHOPHYSIOLOGICAL MECHANISMS, AND INDIVIDUAL ILLNESS TRAJECTORIES TO GUIDE TREATMENT SELECTION: New models of mental health care for young people require that interventions be matched to illness type, clinical stage, underlying pathophysiological mechanisms and individual illness trajectories. Narrow syndrome-focused classifications often direct clinical attention away from other key factors such as functional impairment, self-harm and suicidality, alcohol or other substance misuse, and poor physical health. By contrast, we outline a treatment selection guide for early intervention for adolescent-onset mood and psychotic syndromes (ie, active treatments and indicated and more specific secondary prevention strategies). This guide is based on experiences with the Brain and Mind Centre's highly personalised and measurement-based care model to manage youth mental health. The model incorporates three complementary core concepts: ▶A multidimensional assessment and outcomes framework including: social and occupational function; self-harm, suicidal thoughts and behaviours; alcohol or other substance misuse; physical health; and illness trajectory. ▶Clinical stage. ▶Three common illness subtypes (psychosis, anxious depression, bipolar spectrum) based on three underlying pathophysiological mechanisms (neurodevelopmental, hyperarousal, circadian). These core concepts are not mutually exclusive and together may facilitate improved outcomes through a clinical stage-appropriate and transdiagnostic framework that helps guide decisions regarding the provision of appropriate and effective care options. Given its emphasis on adolescent-onset mood and psychotic syndromes, the Brain and Mind Centre's model of care also respects a fundamental developmental perspective - categorising childhood problems (eg, anxiety and neurodevelopmental difficulties) as risk factors and respecting the fact that young people are in a period of major biological and social transition. Based on these factors, a range of social, psychological and pharmacological interventions are recommended, with an emphasis on balancing the personal benefit-to-cost ratio. CHAPTER 5: A SERVICE DELIVERY MODEL TO SUPPORT HIGHLY PERSONALISED AND MEASUREMENT-BASED CARE IN YOUTH MENTAL HEALTH: Over the past decade, we have seen a growing focus on creating mental health service delivery models that better meet the unique needs of young Australians. Recent policy directives from the Australian Government recommend the adoption of stepped-care services to improve the appropriateness of care, determined by severity of need. Here, we propose that a highly personalised approach enhances stepped-care models by incorporating clinical staging and a young person's current and multidimensional needs. It explicitly aims to prevent progression to more complex and severe forms of illness and is better aligned to contemporary models of the patterns of emergence of psychopathology. Inherent within a highly personalised approach is the incorporation of other evidence-based processes, including real-time measurement-based care and use of multidisciplinary teams of health professionals. Data-driven local system modelling and personalised health information technologies provide crucial infrastructure support to these processes for better access to, and higher quality of, mental health care for young people.

Role of biological rhythm dysfunction in the development and management of bipolar disorders: a review

Disturbance of biological rhythms contributes to the onset of bipolar disorders and is an important clinical feature of the condition. To further explore the role of biological rhythms in bipolar disorders, 95 English articles published between 1968 and 2019 were retrieved from the PubMed database and analysed. We herein review the outcomes of studies on biological rhythm disturbance in bipolar disorders, including the epidemiology, aetiology, clinical features (eg, sleep, feeding and eating disorders) and treatment of the condition evaluated by patients’ self-report and biological indicators such as melatonin. Our report supports the characterisation of biological rhythm disturbance as a significant clinical feature affecting the onset and development of bipolar disorders and reviews classical and novel treatments, such as chronotherapy, that can be applied in the clinical practice. Our analysis indicates that a more comprehensive study of the pathophysiology, clinical phenomenology and treatment of biological rhythm disturbance is required.

Sleep and Circadian Rhythm Disorder in Bipolar Affective Disorder

Symptoms of affective disorders encompass a range of changes to biological processes such as sleep and appetite. These processes are regulated over a 24-h cycle known as the circadian rhythm. Sleep is a particularly useful marker of this rhythm as it is readily measurable and functionally significant. Sleep disturbance is common in bipolar affective disorder and may act as a marker, and precipitant, of relapse. Circadian rhythms are modulated by environmental and social cues and have been shown to be influenced by treatment in BPAD. As such understanding of circadian rhythms may lead to a better understanding of the pathophysiology of BPAD and its treatment. This chapter will explore the neurobiology of the circadian clock and the putative role of circadian rhythm dysregulation in the pathophysiology and treatment of bipolar affective disorder (BPAD).

Efficacy of the interpersonal and social rhythm therapy (IPSRT) in patients with bipolar disorder: results from a real-world, controlled trial

BACKGROUND

Bipolar disorder (BD) is one of the most burdensome mental disorders, with a lifetime prevalence of 2.4%, with a prevalence of 0.6% for bipolar type I and 0.4% for bipolar type II. Several interventions have been developed to implement the treatment strategy of bipolar disorder, including the Interpersonal and Social Rhythm Therapy (IPSRT). This intervention has been specifically developed to manage patients' stressful life events, improve the disruptions of social and circadian rhythms and increase adherence to medications. The aim of the present study is to assess the efficacy of IPSRT on affective and anxiety psychopathology, social functioning, response to pharmacological treatment and affective morbidity index (AMI) in BD patients.

METHODS

BD patients were consecutively recruited at the Mood Disorder Unit of the University of Campania "Luigi Vanvitelli" and randomly assigned to the experimental group receiving the IPSRT or to the Treatment as Usual (TAU) group. Patients were assessed at baseline, after 3 and 6 months with several validated assessment tools and with the affective morbidity index.

RESULTS

At the end of the intervention, compared to controls, patients from the experimental group reported a significant improvement in anxious depressive and manic symptomatology, global functioning; and response to mood stabilizers. Patients in the IPSRT group reported a reduction at the AMI score.

CONCLUSIONS

IPSRT has been confirmed to be effective in improving the clinical symptomology of BD patients and in improving the affective morbidity index. Further studies with longer follow-up are needed in order to assess the stability of the results.Trial registration The study was approved by the local ethical review board (N001567/28.01.2018).

Individual experiences of psychological-based interventions for bipolar disorder: A systematic review and thematic synthesis

PURPOSE

To conduct a thematic synthesis to evaluate qualitative studies exploring individuals' experiences of psychological-based interventions for bipolar disorder (BD).

METHOD

A systematic search of relevant databases (Web of Science, PsycINFO, MEDLINE, CINAHL) was conducted using predefined search terms related to 'Bipolar' 'Qualitative method', 'Psychological-based interventions' and 'Adults'. Studies meeting the inclusion criteria were selected and were then evaluated using established quality appraisal criteria. A thematic synthesis was used to synthesize the findings.

RESULTS

From the thematic synthesis, nine analytical themes were derived from the 10 identified research studies. These were helpful and unhelpful aspects of the intervention, increased knowledge of BD, mood recognition, control of moods, change of perspective, mood stability, empowerment, improved relationships and lifestyle changes.

CONCLUSIONS

Findings from the review suggest there were characteristics of psychological-based interventions that individuals with BD valued and which helped facilitate areas of positive change, such as feeling empowered and in control of their moods and other aspects of their lives. However, there were also elements that individuals did not find as helpful and therefore reflects the challenge of a one-size-fits-all model or plan of interventions, compared to a wider recognition of the individuals as being the agent of their recovery. Future qualitative research is needed to explore individual experiences across a range of psychological interventions, in order to further understand the therapeutic processes, which may facilitate recovery.

PRACTITIONER POINTS

Psychological-based interventions for BD need to consider facilitating and measuring empowerment in individuals, rather than focusing just on mood stability. Clinicians with expertise and knowledge in BD should provide timely information to individuals and their families to help increase their understanding of the diagnosis.

Improving functional outcomes in early-stage bipolar disorder: The protocol for the REsearch into COgnitive and behavioural VERsatility trial

AIM

Young people with bipolar disorder (BD) commonly experience reduced quality of life, persistent symptoms and impaired functional recovery despite often superior school performance. Compromised long-term functioning can ensue. There is evidence that psychological therapies alongside pharmacology may be more efficacious earlier in the course of the disorder. Intervention in the early stages may thus reduce the burden and risk associated with BD and mitigate the impact of the disorder on normal developmental trajectories. To date, however, the availability of evidence-based psychological therapies for young people with early BD is limited. Furthermore, there are no large-scale randomized controlled trials (RCTs) of such interventions.

METHODS

The study is a prospective, single-blind, RCT examining the effectiveness of an adjunctive individualized and manualized psychological intervention, compared with treatment as usual within youth-specific early intervention services. The REsearch into COgnitive and behavioural VERsatility (RECOVER) intervention is delivered over a 6-month period. About 122 young people in the early stages of BD-I (at least one manic episode in the previous 2 years, with no more than five lifetime treated/untreated manic or hypomanic episodes) will be recruited. The assessments will occur at baseline, 3, 6 (primary endpoint, end of treatment), 9, 12, 15 and 18 months.

RESULTS

Recruitment will commence in January 2019 and is anticipated to occur over a 3.5-year period.

CONCLUSIONS

To date, there are no evidence-based psychological therapies tailored to young people with early BD. We will test whether early psychological intervention in the course of BD can reduce the symptomatic, psychological, vocational and social impacts that are seen in entrenched disorder.

The chronotherapeutic treatment of bipolar disorders: A systematic review and practice recommendations from the ISBD task force on chronotherapy and chronobiology

AIMS

To systematically review the literature on the efficacy and tolerability of the major chronotherapeutic treatments of bipolar disorders (BD)-bright light therapy (LT), dark therapy (DT), treatments utilizing sleep deprivation (SD), melatonergic agonists (MA), interpersonal social rhythm therapy (IPSRT), and cognitive behavioral therapy adapted for BD (CBTI-BP)-and propose treatment recommendations based on a synthesis of the evidence.

METHODS

PRISMA-based systematic review of the literature.

RESULTS

The acute antidepressant (AD) efficacy of LT was supported by several open-label studies, three randomized controlled trials (RCTs), and one pseudorandomized controlled trial. SD showed rapid, acute AD response rates of 43.9%, 59.3%, and 59.4% in eight case series, 11 uncontrolled, studies, and one RCT, respectively. Adjunctive DT obtained significant, rapid anti-manic results in one RCT and one controlled study. The seven studies on MA yielded very limited data on acute antidepressant activity, conflicting evidence of both antimanic and maintenance efficacy, and support from two case series of improved sleep in both acute and euthymic states. IPSRT monotherapy for bipolar II depression had acute response rates of 41%, 67%, and 67.4% in two open studies and one RCT, respectively; as adjunctive therapy for bipolar depression in one RCT, and efficacy in reducing relapse in two RCTs. Among euthymic BD subjects with insomnia, a single RCT found CBTI-BP effective in delaying manic relapse and improving sleep. Chronotherapies were generally safe and well-tolerated.

CONCLUSIONS

The outcome literature on the adjunctive use of chronotherapeutic treatments for BP is variable, with evidence bases that differ in size, study quality, level of evidence, and non-standardized treatment protocols. Evidence-informed practice recommendations are offered.

Evidence-Based Psychotherapies for Bipolar Disorder

Bipolar disorder is a recurrent psychiatric disorder marked by waxing and waning affective symptoms and impairment in functioning. Some of the morbidity and mortality associated with the illness may be reduced with evidence-based psychotherapies (EBPs) along with pharmacotherapy. To enhance clinicians' understanding of which therapy modalities have evidence supporting their use, the authors conducted a systematic literature review to identify randomized controlled trials (RCTs) of psychotherapy for adults with bipolar disorder. A strong evidence base exists for psychoeducation, cognitive-behavioral therapy, family-focused therapy, interpersonal and social rhythm therapy, and peer-support programs. Promising modalities include functional remediation, mindfulness-based cognitive therapy, illness management and recovery, and technology-assisted strategies. RCTs demonstrate a consistent advantage of these psychotherapies plus pharmacotherapy, compared with the use of pharmacotherapy alone. Adjunctive EBPs hasten time to remission, delay time to recurrence, and improve functional outcomes. EBPs play an important role in helping individuals develop skills needed to manage the persistent and lifelong psychosocial, neurocognitive, vocational, and interpersonal consequences of bipolar disorder. Continued efforts to improve the effectiveness of EBPs for adults with bipolar disorder are warranted.

Psychosocial Interventions for Bipolar II Disorder

Bipolar II disorder causes significant suffering among patients and their families, some of which may be alleviated by psychotherapy alone or as an adjunct to pharmacotherapy. Psychotherapies may be more effective if modified to meet the specific needs of patients with bipolar II disorder.

Improving Functioning, Quality of Life, and Well-being in Patients With Bipolar Disorder

People with bipolar disorder frequently experience persistent residual symptoms, problems in psychosocial functioning, cognitive impairment, and poor quality of life. In the last decade, the treatment target in clinical and research settings has focused not only on clinical remission, but also on functional recovery and, more lately, in personal recovery, taking into account patients' well-being and quality of life. Hence, the trend in psychiatry and psychology is to treat bipolar disorder in an integrative and holistic manner. This literature review offers an overview regarding psychosocial functioning in bipolar disorder. First, a brief summary is provided regarding the definition of psychosocial functioning and the tools to measure it. Then, the most reported variables influencing the functional outcome in patients with bipolar disorder are listed. Thereafter, we include a section discussing therapies with proven efficacy at enhancing functional outcomes. Other possible therapies that could be useful to prevent functional decline and improve functioning are presented in another section. Finally, in the last part of this review, different interventions directed to improve patients' well-being, quality of life, and personal recovery are briefly described.

Treating Circadian Rhythm Disruption in Bipolar Disorder

PURPOSE OF REVIEW

Disruptions in circadian rhythms are believed to underlie the illness course of bipolar disorder (BD). This review evaluates recent studies on the treatment of circadian dysfunction in BD.

RECENT FINDINGS

Targeted social rhythm therapy may be useful for bipolar depression though some studies suggest that a non-targeted psychosocial or pharmacological intervention may be just as efficacious. Lithium holds potential for addressing circadian dysfunction in BD. Blue-blocking therapy may be useful for mania and midday bright light therapy may relieve depression.

CONCLUSIONS

Psychosocial, pharmacological, and light-based approaches are promising avenues for treating circadian dysfunction in BD.

Psychoeducation for psychiatric inpatients following remission of a manic episode in bipolar I disorder: A randomized controlled trial

OBJECTIVE

The aim of the present study was to evaluate the effectiveness of psychoeducation for bipolar I inpatients following remission of a manic episode in a Chinese population.

METHOD

The study recruited currently medicated bipolar I patients, aged 18-60 years, who were in remission from a manic episode, as determined using the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5). Patients were randomized (1:1) to either eight sessions of group-based psychoeducation (active treatment group) or regular free discussions (control group). The primary outcomes were the rates of any type of recurrence and rehospitalization following treatment. The secondary outcomes were changes in mood symptoms, medication adherence, global functioning, as well as treatment response (as measured using the Clinical Global Impression scale). Subjects were assessed at baseline and then at 2 weeks, and 1, 2, 3, 5, 7, 9, and 12 months following treatment.

RESULTS

At 1 year, patients receiving the psychoeducation treatment demonstrated significantly less recurrence. Those in the treatment group also showed a significant reduction in mania recurrence but not depressive recurrence, and psychoeducation increased time to remission. Notably, lower rates of rehospitalization were found in the active treatment group. Those receiving the psychoeducation treatment also revealed higher change from baseline on measures of depression (17-item Hamilton Rating Scale for Depression), mania (Young Mania Rating Scale), global functioning (Clinical Global Impression-severity scale and World Health Organization Disability Assessment Schedule) (P<.05). However, there were no significant group differences for the medication adherence scores.

CONCLUSION

This preliminary evidence suggests that short, group-based psychoeducation benefits currently medicated inpatients following the remission of mania in bipolar I disorder. This intervention warrants further investigation, especially in other Chinese populations. If future studies confirm its benefits, group-based psychoeducation could be incorporated into routine psychiatric inpatient care for bipolar patients in China.

The impact of substance use disorders on recovery from bipolar depression: Results from the Systematic Treatment Enhancement Program for Bipolar Disorder psychosocial treatment trial

OBJECTIVE

Up to 60% of patients with bipolar disorder develop a substance use disorder during their lifetime. The purpose of this paper was to assess the impact of substance use disorders on depression recovery among bipolar patients randomly assigned to different psychotropic medications and psychosocial interventions. We hypothesized that patients with a comorbid substance use disorder would benefit less from psychotherapy regardless of treatment intensity/length compared to patients without a comorbid substance use disorder.

METHOD

We conducted post hoc analyses among bipolar disorder patients ( n = 270) with and without comorbid substance use disorders enrolled in the Systematic Treatment Enhancement Program for Bipolar Disorder randomized psychosocial intervention trial. All patients entered during or shortly after the onset of a bipolar depressive episode. Logistic regression and Cox proportional hazard models were used to assess whether current or past substance use disorders moderated the response of patients to intensive psychosocial intervention or brief psychoeducation with collaborative care, operationalized as full recovery from an episode of bipolar depression.

RESULTS

Current comorbid substance use disorders significantly predicted likelihood of recovery (odds ratio = 2.25, p = 0.025) and time to recovery (odds ratio = 1.71, p = 0.006) from bipolar depression. We found that 74.5% of patients with a current substance use disorder, compared to 56.5% without a current substance use disorder, recovered from bipolar depression. Past substance use disorders did not predict likelihood of recovery or time to recovery. Current substance use disorders did not significantly moderate response to intensive psychotherapy versus collaborative care.

CONCLUSION

Contrary to our hypotheses, bipolar disorder participants with a current comorbid substance use disorder were more likely to recover from psychosocial treatment for bipolar depression than patients without a current comorbid substance use disorder. If this finding is replicated, it has implications for the ordering of treatment for patients with comorbid bipolar disorder and substance use disorders.

Staying well with bipolar disorder: A qualitative analysis of five-year follow-up interviews with young people

WHAT IS ALREADY KNOWN ABOUT THE TOPIC?: Bipolar disorder is a long-term condition which causes ongoing disruptions to the individual's life. Current evidence suggests that a combination of medication in combination with psychotherapy is more effective than medication alone. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: There are few published reports of the effects of interventions (pharmacological or psychotherapeutic) for treatment in bipolar disorder. While both psychotherapies provided a framework for understanding bipolar disorder each had specific strategies that participants identified as effective. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Because bipolar disorder is a long-term condition, its treatment needs to incorporate psychotherapeutic approaches that address the unique nature of its impact on each individual and provide individualized strategies for managing the disorder. Both Interpersonal and Social Rhythm Therapy and Specialist Supportive Care provide strategies that promote personal recovery.

ABSTRACT

Introduction The primary outcomes from this study of psychotherapy for young people with bipolar disorder identified that most participants had continued to remain well. Given that up to 80% of people relapse within 2 years, it was important to establish how these participants described the process of staying well. Aim To examine how participants in a psychotherapy for young people with bipolar disorder study at 5-year follow-up described their experiences of the intervention and its impact on living with the disorder. Methods This qualitative study was conducted 5 years after participants had completed a psychotherapy intervention in a randomized controlled trial for young people with bipolar disorder. Thirty people were recruited into this qualitative study and interviewed regarding their experiences. The data were analysed using an inductive thematic analysis. Findings Three themes were identified from the data: self-awareness in the context of bipolar disorder; understanding my bipolar disorder; and learning to stay well with bipolar disorder. Conclusions Mental health nurses can promote the factors that participants found helpful in learning to stay well self-awareness, understanding the unique characteristics of their disorder, learning to take care of the self and stabilization of social rhythms.

Canadian Network for Mood and Anxiety Treatments (CANMAT) and International Society for Bipolar Disorders (ISBD) 2018 guidelines for the management of patients with bipolar disorder

The Canadian Network for Mood and Anxiety Treatments (CANMAT) previously published treatment guidelines for bipolar disorder in 2005, along with international commentaries and subsequent updates in 2007, 2009, and 2013. The last two updates were published in collaboration with the International Society for Bipolar Disorders (ISBD). These 2018 CANMAT and ISBD Bipolar Treatment Guidelines represent the significant advances in the field since the last full edition was published in 2005, including updates to diagnosis and management as well as new research into pharmacological and psychological treatments. These advances have been translated into clear and easy to use recommendations for first, second, and third- line treatments, with consideration given to levels of evidence for efficacy, clinical support based on experience, and consensus ratings of safety, tolerability, and treatment-emergent switch risk. New to these guidelines, hierarchical rankings were created for first and second- line treatments recommended for acute mania, acute depression, and maintenance treatment in bipolar I disorder. Created by considering the impact of each treatment across all phases of illness, this hierarchy will further assist clinicians in making evidence-based treatment decisions. Lithium, quetiapine, divalproex, asenapine, aripiprazole, paliperidone, risperidone, and cariprazine alone or in combination are recommended as first-line treatments for acute mania. First-line options for bipolar I depression include quetiapine, lurasidone plus lithium or divalproex, lithium, lamotrigine, lurasidone, or adjunctive lamotrigine. While medications that have been shown to be effective for the acute phase should generally be continued for the maintenance phase in bipolar I disorder, there are some exceptions (such as with antidepressants); and available data suggest that lithium, quetiapine, divalproex, lamotrigine, asenapine, and aripiprazole monotherapy or combination treatments should be considered first-line for those initiating or switching treatment during the maintenance phase. In addition to addressing issues in bipolar I disorder, these guidelines also provide an overview of, and recommendations for, clinical management of bipolar II disorder, as well as advice on specific populations, such as women at various stages of the reproductive cycle, children and adolescents, and older adults. There are also discussions on the impact of specific psychiatric and medical comorbidities such as substance use, anxiety, and metabolic disorders. Finally, an overview of issues related to safety and monitoring is provided. The CANMAT and ISBD groups hope that these guidelines become a valuable tool for practitioners across the globe.

Perception of inpatients following remission of a manic episode in bipolar I disorder on a group-based Psychoeducation program: a qualitative study

BACKGROUND

This forms the first study of a group-based psychoeducation program for inpatients following remission of a manic episode in patients suffering from bipolar I disorder in a Chinese population. The aim was to explore the patient's perspectives of the program and their suggestions regarding ways to improve the intervention in the future.

METHODS

Semi-structured and in-depth interviews were conducted with 15 participants who had participated in 8 sessions of a group psychoeducation program over 2 weeks. The verbatim transcripts of those interviews were analysed using thematic analysis.

RESULTS

Five themes emerged from the data, including the patients' perception of participating in the program, their perception of the setting, perception of participating in a group program, perception of the learning content and of the outcome of participating in the program.

CONCLUSIONS

The results presented here describe how the short-term group psychoeducation program was experienced by the patients. Recommendations are also offered to improve the setting, content, and delivery. Our findings provide evidence that the program is beneficial for manic patients with bipolar I disorder, and this intervention warrants further research especially in a Chinese population. If these benefits are confirmed in future studies, this program could be incorporated into routine psychiatric inpatient care in China.

Three-year follow-up after psychotherapy for young people with bipolar disorder

OBJECTIVES

(1) To examine the differences between interpersonal and social rhythm therapy (IPSRT) and specialist supportive care (SSC) in the longer term impacts of IPSRT and SSC on cumulative depression and mania symptoms over a further 78-week follow-up period post treatment. (2) To calculate the survival time before recurrence of a new mood episode over the 3-year period.

METHODS

One hundred young people with bipolar disorder aged between 15 and 36 years who had been randomized to treatment with either IPSRT or SSC for 78 weeks were followed up for a subsequent 78 weeks. The Longitudinal Interval Follow-up Evaluation was completed at 26-week intervals. A Mann-Whitney U test was used to determine if there were significant differences between therapy types and a Kaplan-Meier survival analysis was used to determine time to recurrence. Cox regression was used to assess the association between time to relapse and therapy type.

RESULTS

There were no significant differences between therapies at each of the data points for either depression or mania scores. The mean change in depression and mania in both groups was significantly different for all three follow-up data points. The actuarial cumulative recurrence rates were 53% for IPSRT and 49% for SSC. There was no significant difference between the groups in time to recurrence.

CONCLUSIONS

While there were no significant differences between the two therapies, there was an overall reduction in symptoms in both therapies. There may be sustained benefits in providing intensive psychotherapies in conjunction with pharmacotherapy for young people with bipolar disorder.

Adolescents at clinical-high risk for psychosis: Circadian rhythm disturbances predict worsened prognosis at 1-year follow-up

BACKGROUND

Individuals with psychotic disorders experience disruptions to both the sleep and circadian components of the sleep/wake cycle. Recent evidence has supported a role of sleep disturbances in emerging psychosis. However, less is known about how circadian rhythm disruptions may relate to psychosis symptoms and prognosis for adolescents with clinical high-risk (CHR) syndromes. The present study examines circadian rest/activity rhythms in CHR and healthy control (HC) youth to clarify the relationships among circadian rhythm disturbance, psychosis symptoms, psychosocial functioning, and the longitudinal course of illness.

METHODS

Thirty-four CHR and 32 HC participants were administered a baseline evaluation, which included clinical interviews, 5days of actigraphy, and a sleep/activity diary. CHR (n=29) participants were re-administered clinical interviews at a 1-year follow-up assessment.

RESULTS

Relative to HC, CHR youth exhibited more fragmented circadian rhythms and later onset of nocturnal rest. Circadian disturbances (fragmented rhythms, low daily activity) were associated with increased psychotic symptom severity among CHR participants at baseline. Circadian disruptions (lower daily activity, rhythms that were more fragmented and/or desynchronized with the light/dark cycle) also predicted severity of psychosis symptoms and psychosocial impairment at 1-year follow-up among CHR youth.

CONCLUSIONS

Circadian rhythm disturbances may represent a potential vulnerability marker for emergence of psychosis, and thus, rest/activity rhythm stabilization has promise to inform early-identification and prevention/intervention strategies for CHR youth. Future studies with longer study designs are necessary to further examine circadian rhythms in the prodromal period and rates of conversion to psychosis among CHR teens.
