Insight, duration of untreated psychosis and attachment in first-episode psychosis: prospective study of psychiatric recovery over 12-month follow-up

Multivariable prediction of functional outcome after first-episode psychosis: a crossover validation approach in EUFEST and PSYSCAN

Several multivariate prognostic models have been published to predict outcomes in patients with first episode psychosis (FEP), but it remains unclear whether those predictions generalize to independent populations. Using a subset of demographic and clinical baseline predictors, we aimed to develop and externally validate different models predicting functional outcome after a FEP in the context of a schizophrenia-spectrum disorder (FES), based on a previously published cross-validation and machine learning pipeline. A crossover validation approach was adopted in two large, international cohorts (EUFEST, n = 338, and the PSYSCAN FES cohort, n = 226). Scores on the Global Assessment of Functioning scale (GAF) at 12 month follow-up were dichotomized to differentiate between poor (GAF current < 65) and good outcome (GAF current ≥ 65). Pooled non-linear support vector machine (SVM) classifiers trained on the separate cohorts identified patients with a poor outcome with cross-validated balanced accuracies (BAC) of 65-66%, but BAC dropped substantially when the models were applied to patients from a different FES cohort (BAC = 50-56%). A leave-site-out analysis on the merged sample yielded better performance (BAC = 72%), highlighting the effect of combining data from different study designs to overcome calibration issues and improve model transportability. In conclusion, our results indicate that validation of prediction models in an independent sample is essential in assessing the true value of the model. Future external validation studies, as well as attempts to harmonize data collection across studies, are recommended.

Pathways from childhood trauma to aberrant salience: A structural equation approach to mentalization model

OBJECTIVE

The aim of this study was to explore the relationship between affective disturbances and aberrant salience in the context of childhood trauma, attachment, and mentalization in an analogue study.

METHODS

Using a cross-sectional design, an online community sample completed self-report measures of key variables. Structural equation modelling was used to test childhood trauma's influence on aberrant salience via a set of intermediate risk factors (depression, negative schizotypy, and insecure attachment). These intermediate risk factors were assumed to lead to the proximal risk factors of aberrant salience (i.e., disorganized schizotypy and disorganized attachment) depending on the vulnerability of mentalizing capacity to elevated stress.

RESULTS

The sample (N = 1263) was 78% female and aged between 18 and 35 years. The tested models closely fitted the observed data, revealing significant pathways from childhood trauma to aberrant salience via the hypothesized pathways. The direct effect of childhood trauma on aberrant salience was significant.

CONCLUSION

Findings suggest that the pathway to aberrant salience may be characterized by disorganization of self-state and intersubjectivity as a function of diminishment in mentalizing ability. This may relate to changes in attachment organization and socio-cognitive capacity, which could constitute possible risk factors signalling development of aberrant salience.

Attachment representations in 7-year-old children at familial high risk of schizophrenia or bipolar disorder: Associations with mental disorders and daily functioning: The Danish High Risk and Resilience Study, VIA 7-A population-based cohort study

BACKGROUND

Attachment quality may affect psychological functioning. However, evidence on attachment representations and their correlates in children born to parents with schizophrenia and bipolar disorder is sparse.

METHODS

We compared attachment representations in a Danish sample of 482 children aged 7 years at familial high risk of schizophrenia, bipolar disorder, and population-based controls and examined associations between attachment and mental disorders and daily functioning. Attachment representations were examined with the Story Stem Assessment Profile (SSAP). Mental disorders were ascertained in diagnostic interviews. Daily functioning was assessed with the Children's Global Assessment Scale.

RESULTS

We found no between-group differences in attachment. Higher levels of secure attachment were associated with decreased risk of concurrent mental disorders in the schizophrenia high-risk group. Higher levels of insecure and disorganized attachment were associated with increased risk of mental disorders across the cohort. Higher levels of secure and insecure attachment were associated with better and poorer daily functioning, respectively. In the current study, results regarding defensive avoidance could not be reported due to methodological limitations.

CONCLUSION

Familial high risk of schizophrenia (FHR-SZ) or bipolar disorder is not associated with less secure or more insecure attachment at age 7. Insecure and disorganized attachment representations index risk of mental disorders and poorer functioning. Secure attachment may be a protective factor against mental disorders in children at FHR-SZ. Validation of the SSAP is needed.

States of Mind with Respect to Attachment: a comparative study between women who killed their children and mothers diagnosed with post-partum depression

INTRODUCTION

Attachment theory has been linked with the caregiving system, acting as a drive for a mother's behavior towards her offspring. The most dramatic consequence of distress following maternity is filicide. Despite this, only few studies addressed the attachment models of women who committed filicide, and very little provided comparisons with mothers diagnosed with post-partum depression.

OBJECTIVE

We described the socio-demographic and psychopathological characteristics of mothers who committed filicide. Our aim was to detect differences in the attachment models between mothers who committed filicide, mothers with post-partum depression and control mothers. Participants and setting: We recruited 19 women who committed filicide (group F) along with 52 women with post-partum depression (group D), and 23 control mothers (group C).

METHODS

We administered a semi-structured interview on socio-demographic aspects and psychiatric history along with the Adult Attachment Interview. We performed an ANOVA, a post-hoc analysis and a logistic regression.

RESULTS

The logistic regression showed a higher prevalence of Dismissing and Disorganized attachments in women of group F compared with group C (p = 0.002, p = 0.007). Dismissing attachment was also overrepresented in group D vs group C (p = 0.012). Interestingly, women of group F showed a Preoccupied/entangled attachment to a lesser extent than those of group D, reaching a borderline significance (p = 0.056).

CONCLUSIONS

Disorganized and Dismissing models of attachment are prevalent in women who committed filicide compared with mothers with post-partum depression and controls, while other models of attachment are less frequent. Therefore, attachment could be taken into consideration to define the risk for committing filicide.

Pathways to Mental Health Care in a Defined Geographic Area of Athens

The purpose of the present study was to explore the duration between the onset of psychopathology and the first contact either with a sectorized Community Mental Health Centre (CMHC) of Athens area or other mental health services, identify the pathways to the CMHC as well as possible sociodemographic and clinical factors affecting help-seeking behavior. The sample consisted of 355 individuals who visited the CMHC, but had sought help from another mental health care source prior to their visit to the Centre (group A), and was compared with 398 individuals who had no previous contact with any other psychiatric service (group B). The average duration of untreated mental disorders was found to be 19.85 (SD 23.113) for males of group A and 26.26 (SD 41.158) for males of group B. Among females the mean duration was found to be 18.11 (SD 27.293) for group A and 22.21 (SD 29.440) for group B, a statistically significant difference. In group A, the intervening services referred the clients at an earlier stage. The striking difference is that only eight individuals (2%) of group B (first timers) were diagnosed as suffering from schizophrenia contrasting to the 61 (17.4%) counterparts of group A. Individuals in our study diagnosed with psychosis seemed to have sought help first from other mental health services and delay to visit a CMHC. People who face problems resulting from their interpersonal or professional relationships often choose to have a first contact with a CMHC. Reduction of the delay in treatment will require clearer understanding of the contributing factors. Liaison activities with public and mental health sector services and outreach interventions to increase awareness on the early recognition of psychopathologic symptoms and the need for early referral could reduce the duration of untreated mental disorders.

Attachment Style and Childhood Traumatic Experiences Moderate the Impact of Initial and Prolonged COVID-19 Pandemic: Mental Health Longitudinal Trajectories in a Sample of Italian Women

The impact of the COVID-19 pandemic on mental health has not been clarified yet, with multiple studies warranting a special focus on women and young adults. A sample of 101 Italian women recruited from the general population was evaluated a few weeks before the onset of the pandemic and during the first and the second wave of the pandemic. Depression values at the Brief Symptom Inventory showed an initial increase followed by a stabilization on higher values in respect to the baseline, whereas Phobic Anxiety was stably worsened. Participants with insecure attachment styles and childhood trauma showed higher levels of distress at all timepoints. In many psychopathological domains, moderation analysis showed an unfavorable trend over time for younger participants. The present study seems to confirm a high burden on mental health for women during the COVID-19 pandemic, highlighting young age, insecure attachment style, and childhood trauma as negative prognostic factors.

How does attachment style affect psychosis? A systematic review of causal mechanisms and guide to future inquiry

PURPOSE

The link between attachment and psychosis is now well established, but less is known about the causal mechanisms underlying this relationship. This systematic review synthesises the studies that examine mediating mechanisms in the attachment and psychosis relationship, in both clinical and non-clinical samples.

METHOD

We conducted a database search (PsychINFO, MEDLINE, Web of Science) to identify all eligible studies irrespective of publication status, the language of article or article date. We assessed methodological quality and completed a narrative synthesis given the heterogeneity of studies to date.

RESULTS

We identified 17 papers, comprising 3,672 participants. The relationship between attachment and psychosis is mediated by four variables or groups of variables. There is good evidence for the causal role of affective factors (affective dysregulation and affective disturbances) and cognitive factors (e.g., self-beliefs and self-esteem and beliefs about symptoms). Affective factors differed by attachment style. Tentative evidence was found for the role of duration of untreated psychosis and baseline negative symptoms.

CONCLUSIONS

Cognitive and affective factors mediate the relationship between attachment style and psychosis. Whilst cognitive factors are routinely targeted in recommended psychological interventions for psychosis, affective factors and attachment style are less commonly considered. Psychological therapies may be improved by calibrating cognitive and affective interventions by attachment style, which should be subjected to experimental and then field studies to assess the impact on clinical and recovery outcomes.

PRACTITIONER POINTS

The relationship between attachment and psychosis is now well established, and studies have started to examine mediating mechanisms. Affective and cognitive factors mediate the attachment-psychosis relationship. Affective factors differ by attachment style. There is limited evidence for the duration of untreated psychosis and negative psychotic symptoms as mediating mechanisms, and research replication is needed. Cognitive factors are routinely targeted in recommended psychological therapies for psychosis, but affective factors and attachment style are less commonly considered. Research should be conducted into the effectiveness of psychological therapies which calibrate cognitive and affective interventions, according to attachment style.

The role of attachment and dissociation in the relationship between childhood interpersonal trauma and negative symptoms in psychosis

Negative symptoms have an adverse impact on quality of life and functioning in psychosis. Service users with psychosis have identified negative symptoms as a priority for their recovery. Despite this, there is a lack of effective and targeted psychological interventions for negative symptoms and their underlying mechanisms remain poorly understood. Childhood trauma is a robust risk factor for positive symptoms in psychosis, but the association with negative symptoms is less well established. Our aim was to examine the association between childhood interpersonal trauma and negative symptoms and the psychological mediators of this relationship. Two hundred and forty participants experiencing psychosis completed validated self-report measures of childhood trauma, attachment, dissociation, compartmentalization, and symptoms. Mediation analyses showed that disorganized attachment and dissociative experiences mediated the association between childhood trauma and negative symptoms, when analysed individually and in a combined model. Models adjusted for age and positive and depressive symptoms. Avoidant attachment and compartmentalization were independently associated with negative symptoms but not childhood trauma and thus were not significant mediators. Childhood trauma was not independently associated with negative symptoms. This paper is the first to present empirical data to support a model implicating attachment and dissociation as important psychological processes in the link between childhood trauma and negative symptoms. These exploratory findings suggest that it may be beneficial to consider these relationships in trauma-informed formulations and interventions. Further longitudinal research is required to establish causality and test theoretical models of mechanisms in the pathway to negative symptoms.

Attachment-based CBT models for psychosis: a PPI-informed approach for acute care settings

People with psychosis often have prolonged in-patient1 admissions at high personal and economic costs. This is due in part to cognitive, affective and behavioural processes that delay recovery and discharge. For many, these processes are affected by enduring insecure attachment styles. People with insecure attachment struggle to manage strong feelings when unwell, and ward staff may struggle to know how best to offer support. Here, we outline the model of interpersonal process in cognitive therapy, and how this may be adapted to capture beliefs and behaviours associated with insecure attachment. Psychological interventions in acute care often fail due to implementation issues. For this reason, and in line with current guidance on developing complex interventions, we report on a series of Patient and Public Involvement (PPI) consultations with people with lived experience of psychosis, family members and ward staff on the potential utility of these attachment-based CBT models. The PPI meetings highlighted three themes: (1) the need to improve staff–patient interactions on wards; (2) continuity in staff–patient relationships is key to recovery; and (3) advantages and barriers to an attachment-based CBT approach. We conclude by describing how the models can be implemented in routine clinical practice, and generalised across services where interpersonal cognitive and behavioural processes may contribute to delays in people’s recovery.

Key learning aims

Persons with first episode psychosis have distinct profiles of social cognition and metacognition

Subjects with first-episode psychosis experience substantial deficits in social cognition and metacognition. Although previous studies have investigated the role of profiles of individuals in social cognition and metacognition in chronic schizophrenia, profiling subjects with first-episode psychosis in both domains remains to be investigated. We used latent profile analysis to derive profiles of the abilities in 174 persons with first-episode psychosis using the Beck's Cognitive Insight Scale, the Faces Test, the Hinting Task, the Internal, Personal and Situational Attributions Questionnaire, and the Beads Task. Participants received a clinical assessment and a neuropsychological assessment. The best-fitting model was selected according to the Bayesian information criterion (BIC). We assessed the importance of the variables via a classification tree (CART). We derived three clusters with distinct profiles. The first profile (33.3%) comprised individuals with low social cognition. The second profile (60.9%) comprised individuals that had more proneness to present jumping to conclusions. The third profile (5.7%) presented a heterogeneous profile of metacognitive deficits. Persons with lower social cognition presented worse clinical and neuropsychological features than cluster 2 and cluster 3. Cluster 3 presented significantly worst functioning. Our results suggest that individuals with FEP present distinct profiles that concur with specific clinical, neuropsychological, and functional challenges. Each subgroup may benefit from different interventions.

Adult Attachment and Personal, Social, and Symptomatic Recovery From Psychosis: Systematic Review and Meta-Analysis

Despite growing evidence for the role of attachment in psychosis, no quantitative review has yet been published on the relationship in this population between insecure attachment and recovery in a broad sense. We therefore used meta-analytic techniques to systematically appraise studies on the relationship between attachment and symptomatic, social and personal recovery in clients with a psychotic disorder. Using the keywords attachment, psychosis, recovery and related terms, we searched six databases: Embase, Medline Epub (OVID), Psycinfo (OVID), Cochrane Central (trials), Web of Science, and Google Scholar. This yielded 28 studies assessing the associations between adult attachment and recovery outcome in populations with a psychotic disorder. The findings indicated that insecure anxious and avoidant attachment are both associated with less symptomatic recovery (positive and general symptoms), and worse social and personal recovery outcomes in individuals diagnosed with a psychotic disorder. The associations were stronger for social and personal recovery than for symptomatic recovery. Attachment style is a clinically relevant construct in relation to the development and course of psychosis and recovery from it. Greater attention to the relationship between attachment and the broad scope of recovery (symptomatic, social, and personal) will improve our understanding of the illness and efficacy of treatment for this population.

An attachment perspective on the risk for psychosis: Clinical correlates and the predictive value of attachment patterns and mentalization

BACKGROUND

In a longitudinal design, the present study examined: (a) the nature of attachment patterns and reflective functioning (RF) in individuals at ultra-high risk for psychosis (UHR); (b) the association between RF and subclinical psychotic symtoms; and (c) the psychosis-predictive value of attachment patterns, RF, and the interaction between these factors.

METHOD

The sample comprised 57 UHR subjects and 53 clinical controls (non-UHR). UHR subjects were followed over a mean period of 14 months (SD = 2.7; range 11-19), during which time 11.5% developed psychosis. Attachment patterns and RF were measured. Hierarchical logistic regression was used to examine the predictive value of variables in the transition to psychosis.

RESULTS

At baseline, significant differences were found between groups in secure attachment patterns and RF. RF was negatively associated with the attenuated psychotic symptoms described by the Unusual Thought Content/Delusional Ideas, Suspiciousness/Persecutory Ideas, and Disorganized Communication subscales. Moreover, poor mentalization was related to an increased likelihood of developing a psychotic disorder (OR = 0.427, 95% CI [0.188, 0.970]); conversely, no predictive effects of the attachment variables and their interaction with RF on the transition to psychosis were found. Notably, an optimal threshold value of RF = 1.25 was found to distinguish UHR subjects who made the transition to psychosis from those who did not develop this pathology.

CONCLUSION

The results suggest that aberrant mentalizing patterns can predict the development of psychosis. Clinical implications of these results for the development of preventive treatments are discussed.

Impact of attachment imagery on paranoia and mood: evidence from two single case studies

Background:

Cognitive behavioural therapy (CBT) for psychosis currently yields modest outcomes and must be improved. Attachment imagery may be an effective means of reducing severity of paranoid beliefs and associated affect. Experimental studies have demonstrated these effects in non-clinical groups. The impact in clinical populations remains untested.

Aims:

This study assessed the impact of a brief attachment imagery task on paranoia and mood, in two people with a diagnosis of schizophrenia.

Method:

Two single case studies are presented. Both participants were working age adults with persecutory delusions. The study utilised an A-B-A design. Participants were recruited for a 6-week period, with a 2- and 3-week baseline respectively, 1-week intervention phase, and follow-up phase matched to duration of baseline. Trait paranoia and attachment were measured at the start of the baseline. State paranoia and affect were measured daily over the 6-week period.

Results:

For both participants, the baseline phase was characterised by high and variable levels of paranoia, which reduced during the intervention phase, with a return to baseline scores at follow-up. We found a similar pattern for negative affect, and the reverse pattern for positive affect.

Conclusions:

Attachment imagery may function as an effective emotion regulation strategy for people with psychosis. Continued use is likely to be needed to maintain gains. This brief task could prove valuable to people needing skills to manage paranoia and mood, and give clinicians confidence that people can manage short-term distress in CBT for psychosis, for example when addressing past trauma.

Attachment Style and Insight in Schizophrenia: a Cross-Sectional Study

Attachment theory provides a model for understanding impairments in social and interpersonal functioning. Schizophrenia is a neuropsychiatry disorder frequently associated with compromised social functioning and limited social support networks. However, the relationship between attachment style and psychopathology dimensions, including insight, isn't fully understood To determine whether there is a relationship between the attachment style and markers for severity of schizophrenia and insight. We conducted a cross-sectional study of 41 patients with schizophrenia and 34 patients with non-psychotic disorders used as a control group. Patients were assessed using semi-structured diagnostic interviews and self-reporting questionnaires, including Adult Attachment Scale-Revised. The schizophrenia group was also given the Positive and Negative Syndrome Scale and the Markova and Berrios Insight Scale. Insecure attachment was overrepresented in the schizophrenic group, and this difference was mainly accounted for lower levels of dependence, representing a moderate effect size (Cohen's d = 0.32). In the schizophrenia group, the closeness and the dependence subscale were negatively correlated with psychopathology severity. Using a multiple regression analysis, the insight was predicted by attachment anxiety, accounting for 20% of the total variance (R² = 0.199, p <0.05). Our data confirm previous evidence that insecure attachment is associated with schizophrenia and suggest that the less comfortable the patient is with closeness and intimacy the greater the severity of symptoms. Furthermore, our findings indicate that higher separation anxiety might predict a better insight.

Pathways from insecure attachment dimensions to paranoia: The mediating role of hyperactivating emotion regulation versus blaming others

OBJECTIVES

There is evidence of associations between insecure attachment and paranoia, but we do not yet fully understand the mediating mechanisms. Attachment theory emphasizes differential relatedness of insecure attachment dimensions (i.e., anxiety vs. avoidance) with specific emotion regulation styles (ER). We tested whether the associations between attachment anxiety versus avoidance and paranoia were mediated specifically by hyperactivating (i.e., the use of emotion-amplifying strategies: self-blame, rumination, catastrophization) versus blaming others ER, respectively. In addition, we explored whether self-blame versus blaming others ER differentially mediated the associations between attachment anxiety versus avoidance and paranoia.

METHOD

We included 60 patients with psychosis and 40 healthy controls (HCs) with whom we conducted standardized diagnostic interviews. We assessed paranoia, attachment, and ER via questionnaires. A structural equation mediation model including attachment anxiety and avoidance (predictor), the ER styles (mediators), and paranoia (outcome) was calculated.

RESULTS

Compared with HCs, patients exhibited significantly more attachment anxiety and avoidance, and used more hyperactivating ER as well as strategies of blaming others. We found a significant indirect effect between attachment anxiety and paranoia via hyperactivating ER in patients with psychosis. However, no significant indirect effects involving blaming others or self-blame in any of the groups were found.

CONCLUSIONS

Our study provides a starting point for further investigation of how paranoid delusions in psychosis could emerge from insecure attachment via ER. This might inspire further research into attachment theories of ER in paranoia. In the long term, this could provide a basis to develop interpersonally oriented interventions for this target group.

PRACTITIONER POINTS

In individuals with psychosis, there appears to be an attachment-specific emotion regulation (ER) pathway from attachment anxiety via hyperactivating ER to paranoia. Blaming others did not explain the significant association between attachment avoidance and paranoia. Attachment-specific therapeutic approaches to paranoia, that focus on hyperactivating ER, could be a valid way to ameliorate paranoid delusions.

Levels of Structural Integration Mediate the Impact of Metacognition on Functioning in Non-affective Psychosis: Adding a Psychodynamic Perspective to the Metacognitive Approach

Synthetic metacognition is defined by integrative and contextualizing processes of discrete reflexive moments. These processes are supposed to be needed to meet intrapsychic as well as interpersonal challenges and to meaningfully include psychotic experience in a personal life narrative. A substantial body of evidence has linked this phenomenon to psychosocial functioning and treatment options were developed. The concept of synthetic metacognition, measured with the Metacognition Assessment Scale-Abbreviated (MAS-A), rises hope to bridge gaps between therapeutic orientations and shares valuable parallels to modern psychodynamic constructs, especially the 'levels of structural integration' of the Operationalized Psychodynamic Diagnosis (OPD-2). As theoretical distinctions remain, aim of this study was to compare the predictive value of both constructs with regard to psychosocial functioning of patients with non-affective psychoses, measured with the International Classification of Functioning, Disability and Health (MINI-ICF-APP). It was further explored if levels of structural integration (OPD-LSIA) would mediate the impact of metacognition (MAS-A) on function (MINI-ICF-APP). Expert ratings of synthetic metacognition (MAS-A), the OPD-2 'levels of structural integration' axis (OPD-LSIA), psychosocial functioning (MINI-ICF-APP) and assessments of general cognition and symptoms were applied to 100 individuals with non-affective psychoses. Whereas both, MAS-A and OPD-LSIA, significantly predicted MINI-ICF-APP beyond cognition and symptoms, OPD-LSIA explained a higher share of variance and mediated the impact of MAS-A on MINI-ICF-APP. Levels of structural integration, including the quality of internalized object representations and unconscious interpersonal schemas, might therefore be considered as valuable predictors of social functioning and as one therapeutic focus in patients with non-affective psychoses. Structural integration might go beyond and form the base of a person's actual reflexive and metacognitive capabilities. Psychotherapeutic procedures specific for psychoses may promote and challenge a patient's metacognitive capacities, but should equally take the need for maturing structural skills into account. Modern psychodynamic approaches to psychosis are shortly presented, providing concepts and techniques for the implicit regulation of interpersonal experience and aiming at structural integration in this patient group.

Development and validation of multivariable prediction models of remission, recovery, and quality of life outcomes in people with first episode psychosis: a machine learning approach

BACKGROUND

Outcomes for people with first-episode psychosis are highly heterogeneous. Few reliable validated methods are available to predict the outcome for individual patients in the first clinical contact. In this study, we aimed to build multivariable prediction models of 1-year remission and recovery outcomes using baseline clinical variables in people with first-episode psychosis.

METHODS

In this machine learning approach, we applied supervised machine learning, using regularised regression and nested leave-one-site-out cross-validation, to baseline clinical data from the English Evaluating the Development and Impact of Early Intervention Services (EDEN) study (n=1027), to develop and internally validate prediction models at 1-year follow-up. We assessed four binary outcomes that were recorded at 1 year: symptom remission, social recovery, vocational recovery, and quality of life (QoL). We externally validated the prediction models by selecting from the top predictor variables identified in the internal validation models the variables shared with the external validation datasets comprised of two Scottish longitudinal cohort studies (n=162) and the OPUS trial, a randomised controlled trial of specialised assertive intervention versus standard treatment (n=578).

FINDINGS

The performance of prediction models was robust for the four 1-year outcomes of symptom remission (area under the receiver operating characteristic curve [AUC] 0·703, 95% CI 0·664-0·742), social recovery (0·731, 0·697-0·765), vocational recovery (0·736, 0·702-0·771), and QoL (0·704, 0·667-0·742; p<0·0001 for all outcomes), on internal validation. We externally validated the outcomes of symptom remission (AUC 0·680, 95% CI 0·587-0·773), vocational recovery (0·867, 0·805-0·930), and QoL (0·679, 0·522-0·836) in the Scottish datasets, and symptom remission (0·616, 0·553-0·679), social recovery (0·573, 0·504-0·643), vocational recovery (0·660, 0·610-0·710), and QoL (0·556, 0·481-0·631) in the OPUS dataset.

INTERPRETATION

In our machine learning analysis, we showed that prediction models can reliably and prospectively identify poor remission and recovery outcomes at 1 year for patients with first-episode psychosis using baseline clinical variables at first clinical contact.

Predicting therapy success from the outset: The moderating effect of insight into the illness on metacognitive psychotherapy outcome among persons with schizophrenia

The degree to which a person recognizes their mental disorder, attributes symptoms to the disorder, and recognizes that treatment may be necessary is frequently referred to as clinical insight. The current study investigates whether clinical insight at baseline moderates the effects on metacognitive capacity of 40 sessions of metacognitive reflection and insight therapy among 35 participants with psychosis. Findings showed that clinical insight did not predict drop-out from therapy. Multilevel analyses provided support for our hypotheses that insight at baseline significantly moderates metacognitive gains at both postmeasurement and follow-up. Our findings demonstrate that lacking clinical insight substantially hampers the effect of this psychosocial intervention. We posit that research efforts should shift from developing interventions, which enhance clinical insight, to interventions, which are effective in absence of clinical insight.

Treatment outcomes and associations in an adolescent-specific early intervention for psychosis service

AIM

Compared with adult onset psychosis, adolescent psychosis has been associated with poorer outcomes in terms of social and cognitive functioning and negative symptoms. Young people experiencing first episode psychosis have developmental needs that frequently pre-date and are compounded by psychosis onset (a previous study). There is a lack of published studies of adolescent onset psychosis and further information is needed so that developmentally appropriate interventions can be developed. We report an observational naturalistic cohort study of an adolescent specific service, the Early Psychosis Support service (EPSS).

METHOD

We examined baseline demographic and clinical variables, treatments outcomes and predictors of outcome for this population.

RESULTS

The mean age of our sample was 16.3 years. Median duration of untreated illness (DUI) was 88 weeks, and median duration of untreated psychosis (DUP) was 16 weeks. We found significant improvements in positive symptoms, negative symptoms, disorganization, excitement, emotional distress and depression from 0 to 12 months. We found that baseline positive symptoms and DUI significantly predicted positive symptoms at 12 months and only negative symptoms at baseline predicted 12-month negative symptoms.

CONCLUSION

Our finding that specialist early intervention for adolescents experiencing psychosis is effective suggests that such treatment should be routinely offered in line with existing clinical guidelines. Our finding that DUI is predictive of poorer outcome at 12 months suggests that even earlier intervention from a specialist team may further improve treatment outcomes.

The role of attachment anxiety in the relationship between childhood trauma and schizophrenia-spectrum psychosis

Childhood trauma (CT) is a comprehensive concept encompassing experiences of sexual, physical, and emotional abuse, and neglect during childhood and adolescence. Patients with schizophrenia-spectrum psychosis (SSP) display higher rates of CT than healthy controls. Among the potential mediators of this association, insecure attachment has gained attention and empirical validation. The present study aimed to extend existing knowledge on this field by exploring the role of the two attachment dimensions, attachment anxiety and attachment avoidance, in the CT-SSP association. A clinical sample of 63 SSP inpatients was compared to a healthy control group on CT and attachment style measures. Correlations between CT, attachment dimensions and psychopathology were sought. Mediation analyses were also performed to examine whether attachment anxiety and/or attachment avoidance mediated the CT-SSP association. Patients displayed higher rates of CT and insecure attachment than controls. Attachment anxiety and severity of Mother Antipathy were linked to severity of hallucinations. Attachment anxiety was recognized as the sole mediator of the CT-SSP association. Our findings suggest that individuals with severe CT and increased attachment anxiety represent a risk population warranting early clinical attention, regular monitoring and tailored therapeutic interventions aimed at reducing the psychological impact of trauma.

Cognitive capacity similarly predicts insight into symptoms in first- and multiple-episode psychosis

BACKGROUND

Lack of insight is a frequent characteristic of psychotic disorders, both in patients who recently experienced a first episode of psychosis (FEP) and those who experience recurrent multiple episodes (MEP). Insight is a multifaceted construct: its clinical form notably includes the unawareness of being ill, of symptoms, and of the need for treatment. Cognitive capacity is among the key determinants of insight into symptoms, but less is known about whether stage of illness (FEP vs. MEP) moderates this association.

METHODS

Our aim is to evaluate the association between cognitive capacity and symptom unawareness using structural equation modeling and moderated multiple regression. A total of 193 FEP and MEP patients were assessed using the CogState battery and the Scale to Assess Unawareness of Mental Disorder.

RESULTS

Analyses suggest that cognitive capacity accounts for a relatively small proportion of the total variation in symptom unawareness (6.4%). There was no evidence to suggest a moderating effect of stage of illness on this association.

CONCLUSIONS

The effect of general cognitive capacity on symptom unawareness is relatively small, and this basic relation was unrelated to stage of illness. It is possible that stage of illness could moderate this association only for certain facets of insight not assessed in this study (e.g., unawareness of the need for treatment).

Predicting one-year outcome in first episode psychosis using machine learning

BACKGROUND

Early illness course correlates with long-term outcome in psychosis. Accurate prediction could allow more focused intervention. Earlier intervention corresponds to significantly better symptomatic and functional outcomes. Our study objective is to use routinely collected baseline demographic and clinical characteristics to predict employment, education or training (EET) status, and symptom remission in patients with first episode psychosis (FEP) at one-year.

METHODS AND FINDINGS

83 FEP patients were recruited from National Health Service (NHS) Glasgow between 2011 and 2014 to a 24-month prospective cohort study with regular assessment of demographic and psychometric measures. An external independent cohort of 79 FEP patients were recruited from NHS Glasgow and Edinburgh during a 12-month study between 2006 and 2009. Elastic net regularised logistic regression models were built to predict binary EET status, period and point remission outcomes at one-year on 83 Glasgow patients (training dataset). Models were externally validated on an independent dataset of 79 patients from Glasgow and Edinburgh (validation dataset). Only baseline predictors shared across both cohorts were made available for model training and validation. After excluding participants with missing outcomes, models were built on the training dataset for EET status, period and point remission outcomes and externally validated on the validation dataset. Models predicted EET status, period and point remission with receiver operating curve (ROC) area under the curve (AUC) performances of 0.876 (95%CI: 0.864, 0.887), 0.630 (95%CI: 0.612, 0.647) and 0.652 (95%CI: 0.635, 0.670) respectively. Positive predictors of EET included baseline EET and living with spouse/children. Negative predictors included higher PANSS suspiciousness, hostility and delusions scores. Positive predictors for symptom remission included living with spouse/children, and affective symptoms on the Positive and Negative Syndrome Scale (PANSS). Negative predictors of remission included passive social withdrawal symptoms on PANSS. A key limitation of this study is the small sample size (n) relative to the number of predictors (p), whereby p approaches n. The use of elastic net regularised regression rather than ordinary least squares regression helped circumvent this difficulty. Further, we did not have information for biological and additional social variables, such as nicotine dependence, which observational studies have linked to outcomes in psychosis.

CONCLUSIONS AND RELEVANCE

Using advanced statistical machine learning techniques, we provide the first externally validated evidence, in a temporally and geographically independent cohort, for the ability to predict one-year EET status and symptom remission in individual FEP patients.

Metacognitive Deficits Predict Impaired Insight in Schizophrenia Across Symptom Profiles: A Latent Class Analysis

The integrated model of insight in schizophrenia suggests that poor insight is the result of multiple factors which compromise persons' abilities to integrate streams of information into a personal awareness of psychiatric challenges, and make adaptive responses. This model hypothesizes that metacognitive deficits, or difficulties forming a complex and integrated understanding of the self and others, influence insight, regardless of other proximal causes including clinical profile. To explore this possibility, we performed a latent class analysis on 324 adults with schizophrenia or schizoaffective disorder. This analysis produced 4 groups on the basis of assessment of insight and Positive and Negative Syndrome Scale (PANSS) positive, negative, cognitive, and hostility symptoms. The resultant groups were characterized as: Good Insight/Low Symptoms (n = 71), Impaired Insight/High Negative Symptoms, (n = 43), Impaired Insight/High Positive Symptoms (n = 50) and Impaired Insight/Diffuse Symptoms (n = 160). When we compared metacognitive function as assessed with the Metacognition Assessment Scale - Abbreviated (MAS-A) across groups, we found that the good insight group had better overall metacognition as well as higher levels of self-reflectivity, awareness of the other and mastery as compared to all 3 groups with impaired insight. When controlling for total symptoms, all differences in metacognitive function between the good insight and the impaired insight groups remained significant. These results are consistent with the view that, independent of symptoms, impaired metacognition contributes to difficulties integrating information and hence impedes insight, or awareness of psychiatric challenges. Consistent with extant literature, results suggest that interventions focusing on metacognition as the target may lead to improved insight.

Negative symptoms of psychosis: A life course approach and implications for prevention and treatment

AIM

Negative symptoms are a cause of enduring disability in serious mental illness. In spite of this, the development of effective treatments for negative symptoms has remained slow. The challenge of improving negative symptom outcomes is compounded by our limited understanding of their aetiology and longitudinal development.

METHODS

A literature search was conducted for life course approach of negative symptoms using PubMed. Further articles were included following manual checking of reference lists and other search strategies. The paper contains a theoretical synthesis of the literature, summarized using conceptual models.

RESULTS

Negative symptom definitions are compared and considered within a context of the life course. Previous studies suggest that several illness phases may contribute to negative symptoms, highlighting our uncertainty in relation to the origin of negative symptoms.

CONCLUSIONS

Similar to other aspects of schizophrenia, negative symptoms likely involve a complex interplay of several risk and protective factors at different life phases. Concepts suggested in this article, such as "negative symptom reserve" theory, require further research, which may inform future prevention and treatment strategies.

Attachment and therapeutic alliance in psychological therapy for people with recent onset psychosis who use cannabis

We examine associations between client attachment style and therapeutic alliance in a 3-arm randomized controlled trial of brief motivational interviewing and cognitive-behavioural therapy compared with longer term motivational interviewing and cognitive-behavioural therapy or standard care alone. Client self-report measures of attachment style were completed at baseline, and both clients and therapists in the treatment arms of the trial completed alliance measures 1 month into therapy. We found that insecure-anxious attachment was positively associated with therapist-rated alliance, whereas clients with insecure-avoidant attachment were more likely to report poorer bond with therapist. There was no evidence that client attachment significantly predicted clinical or substance misuse outcomes either directly or indirectly via alliance. Nor evidence that the length of therapy offered interacted with attachment to predict alliance.

Insight in schizophrenia spectrum disorders: relationship with behavior, mood and perceived quality of life, underlying causes and emerging treatments

Poor insight in schizophrenia is prevalent across cultures and phases of illness. In this review, we examine the recent research on the relationship of insight with behavior, mood and perceived quality of life, on its complex roots, and on the effects of existing and emerging treatments. This research indicates that poor insight predicts poorer treatment adherence and therapeutic alliance, higher symptom severity and more impaired community function, while good insight predicts a higher frequency of depression and demoralization, especially when coupled with stigma and social disadvantage. This research also suggests that poor insight may arise in response to biological, experiential, neuropsychological, social-cognitive, metacognitive and socio-political factors. Studies of the effects of existing and developing treatments indicate that they may influence insight. In the context of earlier research and historical models, these findings support an integrative model of poor insight. This model suggests that insight requires the integration of information about changes in internal states, external circumstances, others' perspectives and life trajectory as well as the multifaceted consequences and causes of each of those changes. One implication is that treatments should, beyond providing education, seek to assist persons with schizophrenia to integrate the broad range of complex and potentially deeply painful experiences which are associated with mental illness into their own personally meaningful, coherent and adaptive picture.

Recovery and serious mental illness: a review of current clinical and research paradigms and future directions

INTRODUCTION

Recovery from serious mental illness has historically not been considered a likely or even possible outcome. However, a range of evidence suggests the courses of SMI are heterogeneous with recovery being the most likely outcome. One barrier to studying recovery in SMI is that recovery has been operationalized in divergent and seemingly incompatible ways: as an objective outcome versus a subjective process. Areas covered: This paper offers a review of recovery as a subjective process and recovery as an objective outcome; contrasts methodologies utilized by each approach to assess recovery; reports rates and correlates of recovery; and explores the relationship between objective and subjective forms of recovery. Expert commentary: There are two commonalities of approaching recovery as a subjective process and an objective outcome: (i) the need to make meaning out of one's experiences to engage in either type of recovery and (ii) there exist many threats to engaging in meaning making that may impact the likelihood of moving toward recovery. We offer four clinical implications that stem from these two commonalities within a divided approach to the concept of recovery from SMI.

The developmental origins of metacognitive deficits in schizophrenia

The deficits in metacognition have been observed in schizophrenia but developmental roots of impaired metacognition are not well understood. Accordingly, this study compared metacognitive abilities of patients with schizophrenia and healthy group and examined the relationship between childhood trauma, attachment style and caregiver attitudes with metacognitive capacity which might contribute to metacognitive deficits in patient group. 35 patients with schizophrenia and 35 healthy people were included in the study. Metacognitive capacity was measured using the Metacognition Assessment Scale Abbreviated (MAS-A). This scale comprises four domains: self-reflectivity, understanding other's mind, decentration and mastery. Group comparisons revealed that schizophrenia patients had greater deficits in metacognitive ability. We found that the report of childhood emotional abuse, a pattern of anxious attachment and over protection by caregivers were uniquely related to metacognitive capacity.

Duration of untreated psychosis: Impact of the definition of treatment onset on its predictive value over three years of treatment

BACKGROUND

While reduction of DUP (Duration of Untreated Psychosis) is a key goal in early intervention strategies, the predictive value of DUP on outcome has been questioned. We planned this study in order to explore the impact of three different definition of "treatment initiation" on the predictive value of DUP on outcome in an early psychosis sample.

METHODS

221 early psychosis patients aged 18-35 were followed-up prospectively over 36 months. DUP was measured using three definitions for treatment onset: Initiation of antipsychotic medication (DUP1); engagement in a specialized programme (DUP2) and combination of engagement in a specialized programme and adherence to medication (DUP3).

RESULTS

10% of patients never reached criteria for DUP3 and therefore were never adequately treated over the 36-month period of care. While DUP1 and DUP2 had a limited predictive value on outcome, DUP3, based on a more restrictive definition for treatment onset, was a better predictor of positive and negative symptoms, as well as functional outcome at 12, 24 and 36 months. Globally, DUP3 explained 2 to 5 times more of the variance than DUP1 and DUP2, with effect sizes falling in the medium range according to Cohen.

CONCLUSIONS

The limited predictive value of DUP on outcome in previous studies may be linked to problems of definitions that do not take adherence to treatment into account. While they need replication, our results suggest effort to reduce DUP should continue and aim both at early detection and development of engagement strategies.

[Clinical and psychopathological aspects of deficit disorders in the structure of initial stages of youth-onset endogenous psychosis]

OBJECTIVE

To study the structure of deficit disorders identified in the initial phase (first 5 years) of youth-onset endogenous psychosis.

MATERIAL AND METHODS

Author examined 232 patients with the first episode of juvenile endogenous psychosis during the period from 2005 to 2015 using integrated phenomenological and clinical/psychopathological approaches. The follow-up was administered to 151 patients.

RESULTS AND CONCLUSION

The working hypothesis on the formation of deficit symptom variants based on the mutual competition of its components was formulated. Identified typological species allowed to hypothesize the existence of continual series of variations of deficit disorders manifested as phenomena with multilateral dependencies, characterized by dynamism and a wide range of modifications and verifiable in remission at the initial stages of attack-like endogenous psychosis.

Attachment and coping in psychosis in relation to spiritual figures

Background

Studies have found higher levels of insecure attachment in individuals with schizophrenia. Attachment theory provides a framework necessary for conceptualizing the development of interpersonal functioning. Some aspects of the attachment of the believer to his/her spiritual figure are similar to those between the child and his/her parents. The correspondence hypothesis suggests that early child-parent interactions correspond to a person’s relation to a spiritual figure. The compensation hypothesis suggests that an insecure attachment history would lead to a strong religiousness/spirituality as a compensation for the lack of felt security. The aim of this study is to explore attachment models in psychosis vs. healthy controls, the relationships between attachment and psychopathology and the attachment processes related to spiritual figures.

Methods

Attachment models were measured in 30 patients with psychosis and 18 controls with the AAI (Adult Attachment interview) in relationship with psychopathology. Beliefs and practices related to a spiritual figure were investigated by qualitative and quantitative analyses.

Results

Patients with psychosis showed a high prevalence of insecure avoidant attachment. Spiritual entities functioned like attachment figures in two thirds of cases. Interviews revealed the transformation of internal working models within relation to a spiritual figure: a compensation process was found in 7 of the 32 subjects who showed a significant attachment to a spiritual figure.

Conclusions

Attachment theory allows us to highlight one of the underlying dimensions of spiritual coping in patients with psychosis.

Therapist-client relationships in a psychological therapy trial for psychosis and substance misuse

BACKGROUND

This study aimed to explore factors associated with outcomes in a randomised controlled trial of integrated motivational interviewing and cognitive behavioural therapy for psychosis and substance misuse.

METHOD

Clients and therapists completed self-report measures of alliance and clients completed a self-report measure of adult attachment. Trial therapists were also asked to identify challenges in therapy, client strengths and reasons for client making and not making changes in relation to substance misuse.

RESULTS

Neither therapist-rated nor client-rated alliance was significantly related to objective outcomes. Client insecure attachment avoidance was associated with poorer symptoms and functioning at 12 and 24 months; although not changes in substance misuse. Therapists' perceptions of therapeutic processes (e.g., challenges to therapy, client strengths, client reasons for change and alliance) were consistent with previous literature. Therapists' perceptions of client improvement were associated with reductions in substance use at the end of treatment and their ratings of therapeutic alliance.

CONCLUSION

Insecure adult attachment styles may be a potentially important predictor of symptom outcomes for people with psychosis and substance misuse. Trial therapists may also provide an important source of information about therapeutic processes and factors associated with outcome.

Insecure attachment is associated with paranoia but not hallucinations in psychotic patients: the mediating role of negative self-esteem

BACKGROUND

A growing body of research has investigated associations between insecure attachment styles and psychosis. However, despite good theoretical and epidemiological reasons for hypothesising that insecure attachment may be specifically implicated in paranoid delusions, few studies have considered the role it plays in specific symptoms.

METHOD

We examined the relationship between attachment style, paranoid beliefs and hallucinatory experiences in a sample of 176 people with a diagnosis of schizophrenia spectrum disorders and 113 healthy controls. We also investigated the possible role of negative self-esteem in mediating this association.

RESULTS

Insecure attachment predicted paranoia but not hallucinations after co-morbidity between the symptoms was controlled for. Negative self-esteem partially mediated the association between attachment anxiety and clinical paranoia, and fully mediated the relationship between attachment avoidance and clinical paranoia.

CONCLUSIONS

It may be fruitful to explore attachment representations in psychological treatments for paranoid patients. If future research confirms the importance of disrupted attachment as a risk factor for persecutory delusions, consideration might be given to how to protect vulnerable young people, for example those raised in children's homes.

Metacognitive capacity as a predictor of insight in first-episode psychosis

Impaired insight is common in the first episode of psychosis (FEP). Although considerable research has examined the factors that are associated with impaired insight in chronic psychosis, less is known about the factors that underlie and sustain poor insight in FEP. Impaired metacognition, or the ability to form integrated representations of self and others, is a promising potential contributor to poor insight in FEP. To explore this possibility, the authors assessed insight and metacognition in 40 individuals with FEP and then examined the relationship between these areas and social cognition domains, neurocognitive domains, and psychotic symptoms. Correlation analyses revealed that improved insight was associated with higher metacognition, better vocabulary and Theory of Mind scores, and fewer symptoms. The domain of metacognitive mastery also predicted clinical insight. Results support the need to develop an integrative therapeutic approach focused on improving metacognition, hence addressing poor insight in FEP.

Orbitofrontal cortex, emotional decision-making and response to cognitive behavioural therapy for psychosis

Grey matter volume (GMV) in the orbitofrontal cortex (OFC) may relate to better response to cognitive behavioural therapy for psychosis (CBTp) because of the region׳s role in emotional decision-making and cognitive flexibility. This study aimed to determine the relation between pre-therapy OFC GMV or asymmetry, emotional decision-making and CBTp responsiveness. Emotional decision-making was measured by the Iowa Gambling task (IGT). Thirty patients received CBTp+standard care (CBTp+SC; 25 completers) for 6-8 months. All patients (before receiving CBTp) and 25 healthy participants underwent structural magnetic resonance imaging. Patients׳ symptoms were assessed before and after therapy. Pre-therapy OFC GMV was measured using a region-of-interest approach, and IGT performance was measured as overall learning, attention to reward, memory for past outcomes and choice consistency. Both these measures, were comparable between patient and healthy groups. In the CBTp+SC group, greater OFC GMV correlated with positive symptom improvement, specifically hallucinations and persecution. Greater rightward OFC asymmetry correlated with improvement in several negative and general psychopathology symptoms. Greater left OFC GMV was associated with lower IGT attention to reward. The findings suggest that greater OFC volume and rightward asymmetry, which maintain the OFC׳s function in emotional decision-making and cognitive flexibility, are beneficial for CBTp responsiveness.

An integrated biopsychosocial model of childhood maltreatment and psychosis

There is now a well-established link between childhood maltreatment and psychosis. It is, however, unclear what the mechanisms are by which this occurs. Here, we propose a pathway linking the experience of childhood maltreatment with biological changes in the brain and suggest a psychological intervention to ameliorate its effects.

Delusional Disorder over the Reproductive Life Span: The Potential Influence of Menopause on the Clinical Course

Background and Objectives. Recent evidence supports an association between estrogen levels and severity of psychopathology in schizophrenia women. Our main goal was to investigate whether delusional disorder (DD) women with premenopausal onset and those with postmenopausal onset differ in demographic and clinical features. Methods. Psychopathological symptoms were assessed in 80 DD women (DSM-IV-TR), at baseline and after six and 24 months. Scores in the PANSS, PSP for functionality, HRSD 17 items, C-SSRS for suicide, and the SUMD were considered outcome variables. For comparison purposes, t- and χ (2)-tests were performed and nonparametric tests when necessary. Analysis of Covariance (ANCOVA) was conducted for multivariate comparisons. Results. 57 out of 80 DD women completed the study. When unadjusted, DD with premenopausal onset had a longer DUP, higher educational level, and a tendency toward higher rates of gynaecological disorders. Erotomanic type was most frequent in DD women premenopausal onset, and somatic and jealous types were most frequent in those with postmenopausal onset. After 24 months, DD women with premenopausal onset showed higher depressive symptoms and a tendency toward higher rates of psychotic relapses. Conclusions. Our results support that some aspects of psychopathology and insight may differ according to the onset of DD and the reproductive status.

Attachment in schizophrenia--implications for research, prevention, and treatment

Attachment is a promising area for elucidating psychosocial mechanisms important for development, prevention, and treatment of schizophrenia. This report gives a short summary of studies of attachment in psychosis. It was found that dismissing and disorganized forms of attachment were over-represented in psychosis. Evidence pointed to associations between a dismissing attachment pattern and positive psychotic symptoms, negative symptoms, and poor engagement with services. Furthermore, insecure attachment was found to predict impaired recovery from negative symptoms. Possible major risk processes in development linking dismissing attachment to symptom development were externalizing and deactivation of affects and poor mentalization. For a disorganized form of attachment, possible risk mechanisms were heightened stress-sensitivity and dissociation. Based on this initial evidence, further research in attachment in psychosis focusing on these risk mechanisms seems warranted. In addition, the evidence supported a focus on attachment-related risk processes to enhance the prevention and treatment of psychosis.
