Monitoring Depression Treatment Outcomes With the Patient Health Questionnaire-9

Internet Cognitive Behavioral Therapy for Women With Postnatal Depression: A Randomized Controlled Trial of MumMoodBooster

BACKGROUND

There are few published controlled trials examining the efficacy of Internet-based treatment for postnatal depression (PND) and none that assess diagnostic status (clinical remission) as the primary outcome. This is despite the need to improve treatment uptake and accessibility because fewer than 50% of postnatally depressed women seek help, even when identified as depressed.

OBJECTIVE

In a randomized controlled trial (RCT), we aimed to test the efficacy of a 6-session Internet intervention (the MumMoodBooster program, previously evaluated in a feasibility trial) in a sample of postnatal women with a clinical diagnosis of depression. The MumMoodBooster program is a cognitive behavioral therapy (CBT) intervention, is highly interactive, includes a partner website, and was supported by low-intensity telephone coaching.

METHODS

This was a parallel 2-group RCT (N=43) comparing the Internet CBT treatment (n=21) to treatment as usual (n=22). At baseline and at 12 weeks after enrollment, women's diagnostic status was assessed by telephone with the Standardized Clinical Interview for DSM-IV (SCID-IV) and symptom severity with the Beck Depression Inventory (BDI-II). Depression symptoms were measured repeatedly throughout the study period with the Patient Health Questionnaire (PHQ-9).

RESULTS

At the end of the study, 79% (15/19) of women who received the Internet CBT treatment no longer met diagnostic criteria for depression on the SCID-IV (these outcome data were missing for 2 intervention participants). This contrasted with only 18% (4/22) remission in the treatment as usual condition. Depression scores on the BDI-II showed a large effect favoring the intervention group (d=.83, 95% CI 0.20-1.45). Small to medium effects were found on the PHQ-9 and on measures of anxiety and stress. Adherence to the program was very good with 86% (18/21) of users completing all sessions; satisfaction with the program was rated 3.1 out of 4 on average.

CONCLUSIONS

Our results suggest that our Internet CBT program, MumMoodBooster, is an effective treatment option for women clinically diagnosed with PND. This is one of only two controlled evaluations of specialized online psychological treatment among women clinically diagnosed with PND. MumMoodBooster appears to be a feasible, effective treatment option, which is potentially accessible to large numbers of women in metropolitan, rural, and remote areas. Future work might be focused profitably on establishing comparability with face-to-face treatments and purely self-guided delivery. We have commenced a larger RCT comparing MumMoodBooster with face-to-face CBT.

Membrane-Stabilizing Agents Improve Quality-of-Life Outcomes for Patients with Lumbar Stenosis

Study Design Retrospective cohort controlled study. Objective To determine quality-of-life (QOL) outcomes for patients with lumbar spinal stenosis (LSS) treated with membrane-stabilizing agents (MSAs). Methods Patients with LSS and concordant neurogenic claudication treated with MSAs (n = 701) or conservatively without MSAs (n = 2104) at a single tertiary care hospital were identified. Patient QOL measures (Patient Health Questionnaire-9 [PHQ9], EuroQOL-5 Dimensions [EQ-5D], Pain Disability Questionnaire [PDQ]) were recorded pretreatment and then 4 months following treatment. Propensity score matching was used to account for baseline demographic differences between the two groups. The primary outcome measure was posttreatment improvement in these QOL measures. Results Patients in both groups had statistically significant improvements in the EQ-5D. However, the EQ-5D improvement in the MSA group was significantly greater than the improvement in the control group (0.11 versus 0.06; p = 0.0494). The EQ-5D change in the MSA group also exceeded the minimum clinically important difference, thereby suggesting a clinical significance. Both groups had significant pre- to posttreatment improvements in PDQ and PHQ-9, but these changes were not significantly different between the groups. Conclusion The results of this study suggest that patients with LSS and neurogenic claudication can have greater QOL improvements when treated with MSAs compared with other forms of conservative management without MSAs.

Correlation of quality of life and functional outcome measures for cervical spondylotic myelopathy

OBJECT

Studies comparing surgical treatments for cervical spondylotic myelopathy (CSM) are heterogeneous, using a variety of different quality of life (QOL) outcomes and myelopathy-specific measures. This study sought to evaluate the relationship of these measures to each other, and to better understand their use in evaluating patients with CSM.

METHODS

A retrospective study was performed in all patients with CSM who underwent either ventral or dorsal cervical spine surgery at a single tertiary-care institution between January 2008 and July 2013. Severity of myelopathy was assessed pre- and postoperatively using both the Nurick scale and the modified Japanese Orthopaedic Association (mJOA) classification of disability. Prospectively collected QOL outcomes data included Pain Disability Questionnaire (PDQ), Patient Health Questionnaire–9 (PHQ-9), and EQ-5D. Spearman rank correlations were calculated to assess the construct convergent validity for each pair of health status measures (HSMs). To assess each HSM’s ability to discriminate favorable EQ-5D index, we performed receiver operating characteristic (ROC) curve analysis and assessed the area under the curve (AUC).

RESULTS

A total of 119 patients were included. The PDQ total score had the highest correlation with EQ-5D index (Spearman’s rho = −0.82). Neither of the myelopathy scales (mJOA or Nurick) had strong correlations between themselves (0.41) or with the other QOL measures (absolute value range 0.13–0.49). In contrast, the QOL measures correlated relatively well with each other (absolute value range 0.68–0.97). For predicting favorable EQ-5D outcomes, PDQ total score had an AUC of 0.909. The AUCs were significantly greater for the QOL measures in comparison with the myelopathy measures (AUCs were 0.677 and 0.607 for mJOA and Nurick scale scores, respectively).

CONCLUSIONS

The authors found that all included measures of QOL and CSM-specific (mJOA or Nurick scale) measures were valid and responsive. The PDQ was the most predictive of positive QOL after surgery (as measured by the EQ-5D index) for patients with CSM. The substantially lower correlation between myelopathy and QOL outcomes, compared with the various QOL measures themselves, suggests that these questionnaires are measuring different aspects of the patient experience. Solely assessing the myelopathy or disease-specific signs and symptoms is likely insufficient to fully understand and appreciate clinical outcome in its totality. These questionnaire types should be used together to best evaluate patients pre- and postoperatively.

Evaluating the Psychometric Properties and Responsiveness to Change of 3 Depression Measures in a Sample of Persons With Traumatic Spinal Cord Injury and Major Depressive Disorder

OBJECTIVES

To compare the measurement properties and responsiveness to change of the Patient Health Questionnaire-9 (PHQ-9), the Hopkins Symptom Checklist-20 (HSCL-20), and the Hamilton Depression Rating Scale (HAM-D) in people with spinal cord injury (SCI) diagnosed with major depressive disorder (MDD).

DESIGN

Secondary analysis of depression symptoms measured at 6 occasions over 12 weeks as part of a randomized controlled trial of venlafaxine XR for MDD in persons with SCI.

SETTING

Outpatient and community settings.

PARTICIPANTS

Individuals (N=133) consented and completed the drug trial. Eligibility criteria were age at least 18 years, traumatic SCI, and diagnosis of MDD.

INTERVENTIONS

Venlafaxine XR.

MAIN OUTCOME MEASURES

Patients completed the PHQ-9 and the HSCL-20 depression scales; clinical investigators completed the HAM-D and the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-IV) Dissociative Disorders, which was used as a diagnostic criterion measure.

RESULTS

All 3 instruments were improved with rating scale analysis. The HSCL-20 and the HAM-D contained items that misfit the underlying construct and that correlated weakly with the total scores. Removing these items improved the internal consistency, with floor effects increasing slightly. The HAM-D correlated most strongly with Structured Clinical Interview for DSM-IV Dissociative Disorders diagnoses. Improvement in depression was similar on all outcome measures in both treatment and control groups.

CONCLUSIONS

The psychometric properties of the revised depression instruments are more than adequate for routine use in adults with SCI and are responsive to clinical improvement. The PHQ-9 is the simplest instrument with measurement properties as good as or better than those of the other instruments and required the fewest modifications.

Assessing the effectiveness of enhanced psychological care for patients with depressive symptoms attending cardiac rehabilitation compared with treatment as usual (CADENCE): study protocol for a pilot cluster randomised controlled trial

BACKGROUND

Around 17% of people eligible for UK cardiac rehabilitation programmes following an acute coronary syndrome report moderate or severe depressive symptoms. While maximising psychological health is a core goal of cardiac rehabilitation, psychological care can be fragmented and patchy. This study tests the feasibility and acceptability of embedding enhanced psychological care, composed of two management strategies of proven effectiveness in other settings (nurse-led mental health care coordination and behavioural activation), within the cardiac rehabilitation care pathway.

METHODS/DESIGN

This study tests the uncertainties associated with a large-scale evaluation by conducting an external pilot trial with a nested qualitative study. We aim to recruit and randomise eight comprehensive cardiac rehabilitation teams (clusters) to intervention (embedding enhanced psychological care into routine cardiac rehabilitation programmes) or control (routine cardiac rehabilitation programmes alone) arms. Up to 64 patients (eight per team) identified with depressive symptoms upon initial assessment by the cardiac rehabilitation team will be recruited, and study measures will be administered at baseline (before starting rehabilitation) and at 5 months and 8 months post baseline. Outcomes include depressive symptoms, cardiac mortality and morbidity, anxiety, health-related quality of life and service resource use. Trial data on cardiac team and patient recruitment, and the retention and flow of patients through treatment will be used to assess intervention feasibility and acceptability. Qualitative interviews will be undertaken to explore trial participants' and cardiac rehabilitation nurses' views and experiences of the trial methods and intervention, and to identify reasons why patients declined to take part in the trial. Outcome data will inform a sample size calculation for a definitive trial.

DISCUSSION

The pilot trial and qualitative study will inform the design of a fully powered cluster randomised controlled trial to evaluate the effectiveness and cost-effectiveness of the provision of enhanced psychological care within cardiac rehabilitation programmes.

A Combined Patient and Provider Intervention for Management of Osteoarthritis in Veterans: A Randomized Clinical Trial

BACKGROUND

Management of osteoarthritis requires both medical and behavioral strategies, but some recommended therapies are underused.

OBJECTIVE

To examine the effectiveness of a combined patient and provider intervention for improving osteoarthritis outcomes.

DESIGN

Cluster randomized clinical trial with assignment to osteoarthritis intervention and usual care groups. (ClinicalTrials.gov: NCT01130740).

SETTING

Department of Veterans Affairs Medical Center in Durham, North Carolina.

PARTICIPANTS

30 providers (clusters) and 300 outpatients with symptomatic hip or knee osteoarthritis.

INTERVENTION

The telephone-based patient intervention focused on weight management, physical activity, and cognitive behavioral pain management. The provider intervention involved delivery of patient-specific osteoarthritis treatment recommendations to primary care providers through the electronic medical record.

MEASUREMENTS

The primary outcome was total score on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at 12 months. Secondary outcomes were WOMAC function and pain subscale scores, physical performance (Short Physical Performance Battery), and depressive symptoms (Patient Health Questionnaire-8). Linear mixed models that were adjusted for clustering of providers assessed between-group differences in improvement in outcomes.

RESULTS

At 12 months, WOMAC scores were 4.1 points lower (indicating improvement) in the osteoarthritis intervention group versus usual care (95% CI, -7.2 to -1.1 points; P = 0.009). WOMAC function subscale scores were 3.3 points lower in the intervention group (CI, -5.7 to -1.0 points; P = 0.005). WOMAC pain subscale scores (P = 0.126), physical performance, and depressive symptoms did not differ between groups. Although more patients in the osteoarthritis intervention group received provider referral for recommended osteoarthritis treatments, the numbers who received them did not differ.

LIMITATION

The study was conducted in a single Veterans Affairs medical center.

CONCLUSION

The combined patient and provider intervention resulted in modest improvement in self-reported physical function in patients with hip and knee osteoarthritis.

The effects of optimism and gratitude on adherence, functioning and mental health following an acute coronary syndrome

OBJECTIVE

This study examined the effects of optimism and gratitude on self-reported health behavior adherence, physical functioning and emotional well-being after an acute coronary syndrome (ACS).

METHODS

Among 156 patients, we examined associations between optimism and gratitude measured 2 weeks post-ACS and 6-month outcomes: adherence to medical recommendations, mental and physical health-related quality of life (HRQoL), physical functioning, depressive symptoms and anxiety. Multivariable linear regression models were used, controlling for increasing levels of adjustment.

RESULTS

Optimism [β=.11, standard error (S.E.)=.05, P=.038] and gratitude (β=.10, S.E.=.05, P=.027) at 2 weeks were associated with subsequent self-reported adherence to medical recommendations (diet, exercise, medication adherence, stress reduction) at 6 months in fully adjusted models. Two-week optimism and gratitude were associated with improvements in mental HRQoL (optimism: β=.44, S.E.=.13, P=.001; gratitude: β=.33, S.E.=.12, P=.005) and reductions in symptoms of depression (optimism: β=-.11, S.E.=.05, P=.039; gratitude: β=-.10, S.E.=.05, P=.028) and anxiety (optimism: β=-.15, S.E.=.05, P=.004; gratitude: β=-.10, S.E.=.05, P=.034) at 6 months.

CONCLUSION

Optimism and gratitude at 2 weeks post-ACS were associated with higher self-reported adherence and improved emotional well-being 6 months later, independent of negative emotional states. Optimism and gratitude may help recovery from an ACS. Interventions promoting these positive constructs could help improve adherence and well-being.

Implicit Measure of Life/Death Orientation Predicts Response of Suicidal Ideation to Treatment in Psychiatric Inpatients

In this study, we set out to extend empirical research on the Life-Death Implicit Association Test (IAT) by administering the measure to an adult psychiatric inpatient population with suicidal ideation. We sought to examine its association with other suicide-relevant measures and to determine whether it adds predictive utility beyond that offered by other measures of suicide risk. The IAT was administered (N = 124) at biweekly intervals as part of an assessment battery at an inpatient facility for complex, treatment resistant psychiatric disorders (average length of stay: approximately 6 weeks). Multiple regression procedures were utilized to examine relationships among the measures and their predictive utility with respect to suicidal ideation at discharge. Consistent with prior research with other populations, significant associations were found between IAT performance and explicit (self-report and interview) measures of suicide risk. Moreover, the IAT was found to predict suicidal ideation at discharge above and beyond number of prior suicide attempts and admission scores on measures of depression, suicidal ideation, and hopelessness. Change in IAT performance over the course of treatment was observed. The IAT shows promise as an addition to explicit measures conventionally used to estimate suicide risk in psychiatric patients. These findings are consistent with a cognitive vulnerability model of suicide risk.

Psychometric validation of the depression and family functioning scale

OBJECTIVE

A new patient-reported outcome (PRO) measure developed to assess the impact of major depressive disorder (MDD) on partner and family interactions and quality of relationships, the Depression and Family Functioning Scale (DFFS), was analyzed to establish its reliability, validity, and responsiveness.

METHODS

Data from a multi-center, prospective, 2-year observational study were analyzed to assess the psychometric properties of the DFFS in patients with MDD (nBaseline = 478; nMonth2 = 433). Measures administered to assess validity included the Sheehan Disability Scale (SDS), Arizona Sexual Experiences Scale (ASEX) and Short Form Health Survey-12 (SF-12). Reliability (Cronbach's alphas and intra-class correlations), construct validity (factor analysis and correlations), discriminating ability (analyses of variance), and responsiveness (standardized effect size estimates) were evaluated.

RESULTS

Principal components analyses indicated a single underlying dimension, confirmed by highly satisfactory Cronbach's alphas (αBaseline = 0.85, αMonth2 = 0.89). The DFFS demonstrated satisfactory test-re-test reliability in patients with the same SDS family life/home responsibilities ratings at baseline and month 2 (intraclass correlation = 0.75). Correlations with other measures showed convergent and divergent validity; e.g., the DFFS correlated better with SF-12 mental component scores (rBaseline = -0.35, rMonth2 = -0.49) than with SF-12 physical component scores (rBaseline = -0.05, rMonth2 = -0.31). Hypothesis tests were generally as predicted; many were statistically significant, substantiating DFFS discriminating ability. Standardized effect size estimates of responsiveness ranged from 0.44-0.84, demonstrating that the items were capable of detecting change.

CONCLUSIONS

The psychometric analyses support the reliability, validity, and responsiveness of the DFFS and its usefulness for assessing the impact of depression on family functioning. The DFFS can potentially provide important information not captured in clinical practice and facilitate more comprehensive evaluation of MDD treatments.

The Changes of Psychometric Profiles after Medical Treatment of Lower Urinary Tract Symptoms Suggestive of Benign Prostatic Hyperplasia

Objective

To investigate the relationship of somatization and depression with the degree of lower urinary tract symptoms suggestive of benign prostate hyperplasia (LUTS/BPH) and changes in psychometric profiles including somatization and depression after treatment of LUTS/BPH.

Methods

Subjects were evaluated at baseline and at week 12 following routine treatment for LUTS/BPH using the International Prostate Symptom Score (IPSS) to measure the severity of LUTS/BPH, the Overactive Bladder Symptom Score (OABSS) to measure the severity of OAB, the Patient Health Questionnaire-9 (PHQ-9) to assess depression, and the Patient Health Questionnaire-15 (PHQ-15) to evaluate somatization. The correlation of somatization and depression with the degree of LUTS/BPH symptoms at baseline and changes in somatization and depression after LUTS/BPH treatment were assessed using relevant statistical analyses.

Results

One hundred and twenty patients agreed to participate in this study, and 101 (84.2%) completed the 12-week trial and responded to the study questionnaires. At baseline, total IPSS score was correlated with PHQ-9 (r=0.475, p=0.005) and PHQ-15 (r=0.596, p<0.001) scores. The results after the 12-week treatment clearly show significant improvement in both PHQ-9 (p <0.001) and PHQ-15 (p=0.019) scores, and the PHQ-9 (r=0.509, p=0.048) and PHQ-15 (r=0.541, p=0.016) scores were positively correlated with total IPSS.

Conclusion

Our preliminary results indicated that severity of LUTS is correlated with severity of somatization and depression. Further, the improvement of LUTS after treatment may have positive impacts on somatization and depression.

Depression, substance abuse and stigma among men who have sex with men in coastal Kenya

Objectives

Mental health conditions can erode quality of life and interfere with health-related behaviours such as medication adherence. We aimed to determine the prevalence and correlates of depression and other psychosocial factors among self-identified men who have sex with men (MSM) in coastal Kenya.

Design

A cross-sectional survey.

Methods

Psychosocial and mental health characteristics were assessed in an audio computer-assisted self-interview (ACASI) survey among 112 MSM participating in two ongoing HIV-positive and HIV-negative cohorts in Mtwapa, Kenya.

Results

One-third of participants met criteria for major depressive disorder [16.1%, 95% confidence interval (95% CI) 9.8–24.2] or other depressive disorder (15.2%, 95% CI 9.1–23.2). Alcohol abuse was reported by 45% of respondents (95% CI 35.2–54.3) and other substance abuse by 59.8% (95% CI 50.1–69.0). Sexual and HIV stigma were moderate, with median scores of 11 [interquartile range (IQR) 6–17, potential range 0–33] and 25 (IQR 23–29, potential range 11–44), respectively. There were significant bivariate correlations between alcohol abuse, other substance abuse, sexual stigma and childhood and recent abuse. In a multivariable linear regression model, sexual stigma (beta = 0.17, 95% CI 0.03–0.32) and marriage to a woman (beta = −2.41 95% CI −4.74 to −0.09) were each associated with depression score.

Conclusion

We found moderate to high levels of depression and substance abuse, and moderate levels of sexual stigma. These variables were highly inter-correlated and associated with an experience of trauma or abuse. Comprehensive mental health services are needed in this population to address these issues.

A comparison of multiple patient reported outcome measures in identifying major depressive disorder in people with multiple sclerosis

BACKGROUND

Depression is one of the most prominent and debilitating symptoms in individuals with multiple sclerosis (MS), yet there is currently no consensus on the best instruments for depression screening in MS. More head to head comparisons of available screening instruments are needed to advise MS researchers and clinicians.

METHODS

A cross-sectional comparison of the effectiveness of screening for MDD using multiple patient reported outcome (PRO) screeners against a modified SCID telephone interview was completed in 164 individuals with MS. Stratum goals were set for depression levels to ensure participation by people with borderline and higher levels of depression. Criterion standard was a modified SCID MDD module. PRO measures included the PHQ-9, BDI-FS, PROMIS depression, Neuro-QOL depression, M-PHQ-2, PHQ-2, and CESD.

RESULTS

48 (29%) individuals met the modified SCID criteria for MDD. The sensitivity of the PRO measures ranged from 60% to 100% while specificity ranged from 46% to 86%. The ROC area for the PRO measures ranged from 0.79 to 0.83. Revised (higher) cutoff scores were suggested by the ROC analyses for most self-reported screeners.

LIMITATIONS

Enrollment was stopped early because of difficulties with recruitment. Several SCID recording could not be reviewed and diagnosis confirmed.

CONCLUSIONS

CESD-10 and PHQ9 had the best diagnostic performance using optimal cutoffs, but no one PRO measure stood out as significantly better than any other. Even when revised cutoff scores were used, none of the self-reported screeners identified people with MDD with adequate accuracy. More accurate self-reported screeners would facilitate diagnosing of MDD for both research and clinical purposes.

Promotora assisted depression care among predominately Hispanic patients with concurrent chronic illness: Public care system clinical trial design

Depression frequently negatively affects patient overall self-care and social stress management within United States safety net care systems. Rates of major depression are significantly high among low-income predominantly Hispanic/Latino with chronic illness, such as diabetes and heart disease. The study design of the A Helping Hand to Activate Patient-Centered Depression Care among Low-income Patients (AHH) randomized clinical trial aims to enhance patient depression care receipt and overall bio-psychosocial self-care management. The AHH trial is conducted in collaboration with three Los Angeles County Department of Health Services (DHS) safety net clinics that provide Patient-Centered Medical Home (PCMH) care. The study compares AHH intervention (AHH) in which community-based bilingual promotoras provide in-person or telephone patient engagement and intervention aimed to reduce the burden and strain on patients, families, and care providers by assessing, enhancing, and facilitating patient depression and co-morbid illness self-care management skill, and activating patient communication with clinic medical providers versus DHS PCMH team usual care (PCMHUC). AHH independent bilingual recruiters screened 1957 and enrolled 348 predominantly Hispanic/Latino patients, of whom 296 (85%) had diabetes, 14 (4%) with heart disease, and 38 (11%) with both diseases. Recruiters identified depressed patients by baseline Patient Health Questionnaire-9 scores of 10 or more, completed baseline assessments, and randomized patients to either AHH or PCMHUC study group. The comprehensive assessments will be repeated at 6 and 12months by an independent bilingual follow-up interviewer. Baseline and outcome data include mental health assessment and treatment receipt, co-morbid illness self-care, social relationships, and environmental stressor assessments.

Beneficial Effects of Improvement in Depression, Pain Catastrophizing, and Anxiety on Pain Outcomes: A 12-Month Longitudinal Analysis

Depression, pain catastrophizing, and anxiety commonly co-occur with chronic pain. However, the degree to which improvement in these psychological comorbidities predicts subsequent pain outcomes and, in particular, the relative effects of these 3 psychological factors with respect to each other is only partially known. Longitudinal analysis of 250 primary care patients with chronic musculoskeletal pain enrolled in the Stepped Care to Optimize Pain care Effectiveness (SCOPE) trial was examined, using data gathered at baseline, and at 3 and 12 months. Mixed effects model repeated measures analyses were used to determine if changes in depression, pain catastrophizing, and anxiety predicted a subsequent reduction in pain intensity or interference and pain-related disability. Defining a clinically significant change as twice the standard error of measurement for each predictor, we found that a 2-standard error of measurement improvement in depression, pain catastrophizing, and anxiety resulted in, respectively, an effect size decrease in pain intensity or interference of .45, .33, and .12; a 14%, 12%, and 6% reduction in the number of pain-specific disability days; and a 43%, 30%, and 28% decreased likelihood of high disability (defined as ≥10 pain-specific disability days in the past 4 weeks). In summary, improvements in 3 common psychological comorbidities predicted better pain outcomes.

PERSPECTIVE

Because depression, pain catastrophizing, and anxiety commonly accompany chronic pain and might adversely affect pain outcomes, treatment of these modifiable psychological factors is warranted to optimize the effectiveness of pain-specific therapies.

Use of a specialty clinic to teach a standardized approach to mood disorders in a family medicine residency

The Mood Disorder Clinic was started at the Cone Family Medicine Residency in 2004 with the threefold purpose of providing a patient care service to a largely uninsured or underinsured population; teaching Family Medicine resident physicians how to more accurately identify, diagnose, and treat mood disorders in their patients; and modeling a team-based approach to addressing mental stress, distress, and dysfunction in the primary care setting. The authors present the logistics of the clinic and the standard approach to mood issues that is taught to resident physicians. Formal feedback suggests that the resident physicians find the experience useful in developing psychiatric knowledge and skills.

Using Patient Health Questionnaire-9 item parameters of a common metric resulted in similar depression scores compared to independent item response theory model reestimation

OBJECTIVES

To investigate the validity of a common depression metric in independent samples.

STUDY DESIGN AND SETTING

We applied a common metrics approach based on item-response theory for measuring depression to four German-speaking samples that completed the Patient Health Questionnaire (PHQ-9). We compared the PHQ item parameters reported for this common metric to reestimated item parameters that derived from fitting a generalized partial credit model solely to the PHQ-9 items. We calibrated the new model on the same scale as the common metric using two approaches (estimation with shifted prior and Stocking-Lord linking). By fitting a mixed-effects model and using Bland-Altman plots, we investigated the agreement between latent depression scores resulting from the different estimation models.

RESULTS

We found different item parameters across samples and estimation methods. Although differences in latent depression scores between different estimation methods were statistically significant, these were clinically irrelevant.

CONCLUSION

Our findings provide evidence that it is possible to estimate latent depression scores by using the item parameters from a common metric instead of reestimating and linking a model. The use of common metric parameters is simple, for example, using a Web application (http://www.common-metrics.org) and offers a long-term perspective to improve the comparability of patient-reported outcome measures.

Impact of a Suicide-Specific Intervention within Inpatient Psychiatric Care: The Collaborative Assessment and Management of Suicidality

A growing body of literature indicates that suicidal patients differ from other psychiatric patients with respect to specific psychological vulnerabilities and that suicide-specific interventions may offer benefits beyond conventional care. This naturalistic controlled-comparison trial (n = 52) examined outcomes of intensive psychiatric hospital treatment (mean length of stay 58.8 days), comparing suicidal patients who received individual therapy from clinicians utilizing the Collaborative Assessment and Management of Suicidality (CAMS) to patients whose individual therapists did not utilize CAMS. Propensity score matching was used to control for potential confounds, including age, sex, treatment unit, and severity of depression and suicidality. Results showed that both groups improved significantly over the course of hospitalization; however, the group receiving CAMS showed significantly greater improvement on measures specific to suicidal ideation and suicidal cognition. Results are discussed in terms of the potential advantages of treating suicide risk with a suicide-specific intervention to make inpatient psychiatric treatment more effective in reducing risk for future suicidal crises.

Effect of OnabotulinumtoxinA Injection on Depression in Chronic Migraine

OBJECTIVE

The current study retrospectively evaluated patient reported outcomes (PROs) collected before and after at least 2 sessions of onabotulinumtoxinA (onabot) injections for chronic migraine. Depression was assessed by the Patient Health Questionnaire-9.

METHOD

Chronic migraineurs receiving onabot were identified. In addition to the Patient Health Questionnaire-9 (PHQ9), the European Quality of Life (QOL), 5-Dimension (EQ-5D) (QOL), Headache Impact Test (HIT6), and Pain Disability Index (PDI) were reviewed across ≥2 consecutive onabot injections for 6-12 months. Paired t-tests on patient's questionnaire scores before and after treatment were performed. Analysis of the PHQ9 was restricted to patients with pretreatment scores ≥ 10 (moderate to severe depression). Change in PHQ9 was the primary outcome, and other PROs were also evaluated.

RESULTS

Four hundred twenty-nine patients met the inclusion criteria, and data were gathered from 2010 to 2014. Average age was 45 years, with 85.5% female, and 92.1% Caucasian. There were 127 patients with PHQ9 scores ≥10 at baseline. Their PHQ9 scores improved from 14.4 (high-moderate) pre-onabot to 11.3 (low-moderate) post-onabot (P <.0001, 95% CI = -4.2 to -2.1); PDI improved from 4.3 to 3.8 (P = .0078, 95% CI = -0.7 to -0.1); EQ-5D improved from 0.74 to 0.77 (P = .0078; 95%CI = 0.01 to 0.04); HIT6 improved from 63.3 to 60.5 (P <.0001, 95%CI = -3.4 to -2.2). For comparison, in the PREEMPT onabot regulatory trials, HIT6 changed from 66 to 61.2 after 5 onabot injections at 24 weeks, P < .001.

CONCLUSION

Onabot injections in chronic migraine patients statistically improved depression scores in patients beginning with at least moderate depression and improved scores in headache and quality of life. Onabot injections also decreased impact of headache on daily life.

Reduced Inhibition of Return to Food Images in Obese Individuals

Previous research has shown that obese individuals may be biased towards attending to food over non-food information, and this bias may contribute to the development and/or maintenance of obesity. The present study sought to extend our understanding of maladaptive attentional processing in this population by investigating whether obese individuals have difficulty in disengaging attention from food compared with non-food images, relative to normal-weight controls. To address this question, we measured inhibition of return (IOR) in an attentional cueing task. The participants were 29 obese and 35 normal-weight satiated females without eating disorders. The obese group displayed less IOR to food images than the normal-weight group, while there was no difference in IOR between the groups for non-food images. This suggests that obese females have greater difficulty disengaging attention from food than normal-weight females. Our findings provide a new focus for studies investigating maintenance factors in obesity and are discussed in relation to a theory of incentive-sensitisation.

Depressive Symptoms before and after Treatment of Obstructive Sleep Apnea in Men and Women

STUDY OBJECTIVES

To determine prevalence of depressive symptoms in obstructive sleep apnea (OSA) and the impact of OSA treatment on depression scores.

METHODS

Consecutive new patients referred for investigation of suspected OSA were approached. Consenting patients completed a patient health questionnaire (PHQ-9) for depressive symptoms when attending for laboratory polysomnography. Those with moderate/severe (apneahypopnea index [AHI] ≥ 15 events/h) and/or symptomatic mild OSA (AHI 5-14.99 events/h) were offered continuous positive airway pressure (CPAP) therapy. PHQ-9 was repeated after 3 months of CPAP with compliance recorded. Of a maximum PHQ-9 score of 27, a cut point ≥ 10 (PHQ-9 ≥ 10) was used to indicate presence of clinically significant depressive symptoms.

RESULTS

A total of 426 participants (243 males) were recruited. Mean ± standard deviation body mass index (BMI) was 32.1 ± 7.1 kg/m2 and AHI 33.6 ± 28.9 events/h. PHQ-9 was 10.5 ± 6.1 and independently related to AHI (p < 0.001) and BMI (p < 0.001). In those without OSA, PHQ-9 ≥ 10 was more common in women, but no gender difference was evident with OSA. Of 293 patients offered CPAP, 228 were compliant (mean nightly use > 5 h) over 3 months of therapy. In them, with therapy, AHI decreased from 46.7 ± 27.4 to 6.5 ± 1.6 events/h, PHQ-9 from 11.3 ± 6.1 to 3.7 ± 2.9 and PHQ-9 ≥ 10 from 74.6% to 3.9% (p < 0.001 in each case). Magnitude of change in PHQ-9 was similar in men and women. Antidepressant use was constant throughout.

CONCLUSIONS

Depressive symptoms are common in OSA and related to its severity. They improve markedly with CPAP, implying a relationship to untreated OSA.

Telephone and in-person cognitive behavioral therapy for major depression after traumatic brain injury: a randomized controlled trial

Major depressive disorder (MDD) is prevalent after traumatic brain injury (TBI); however, there is a lack of evidence regarding effective treatment approaches. We conducted a choice-stratified randomized controlled trial in 100 adults with MDD within 10 years of complicated mild to severe TBI to test the effectiveness of brief cognitive behavioral therapy administered over the telephone (CBT-T) (n = 40) or in-person (CBT-IP) (n = 18), compared with usual care (UC) (n = 42). Participants were recruited from clinical and community settings throughout the United States. The main outcomes were change in depression severity on the clinician-rated 17 item Hamilton Depression Rating Scale (HAMD-17) and the patient-reported Symptom Checklist-20 (SCL-20) over 16 weeks. There was no significant difference between the combined CBT and UC groups over 16 weeks on the HAMD-17 (treatment effect = 1.2, 95% CI: -1.5-4.0; p = 0.37) and a nonsignificant trend favoring CBT on the SCL-20 (treatment effect = 0.28, 95% CI: -0.03-0.59; p = 0.074). In follow-up comparisons, the CBT-T group had significantly more improvement on the SCL-20 than the UC group (treatment effect = 0.36, 95% CI: 0.01-0.70; p = 0.043) and completers of eight or more CBT sessions had significantly improved SCL-20 scores compared with the UC group (treatment effect = 0.43, 95% CI: 0.10-0.76; p = 0.011). CBT participants reported significantly more symptom improvement (p = 0.010) and greater satisfaction with depression care (p < 0.001), than did the UC group. In-person and telephone-administered CBT are acceptable and feasible in persons with TBI. Although further research is warranted, telephone CBT holds particular promise for enhancing access and adherence to effective depression treatment.

PROTECT: A Pilot Program to Integrate Mental Health Treatment Into Elder Abuse Services for Older Women

The goal of this pilot program was to test the usefulness of adapted Problem-Solving Therapy (PST) and anxiety management, called PROTECT, integrated into elder abuse services to reduce depression and improve self-efficacy. Depressed women victims were randomized to receive elder abuse resolution services combined with either PROTECT or a mental health referral. At follow-up, the PROTECT group showed greater reduction in depressive symptoms and endorsed greater improved self-efficacy in problem-solving when compared to those in the Referral condition. These preliminary findings support the potential usefulness of PROTECT to alleviate depressive symptoms and enhance personal resources among abused older women.

Long-Term Clinical Outcomes from a Randomized Controlled Trial of Two Implementation Strategies to Promote Collaborative Care Attendance in Community Practices

This randomized controlled implementation study compared the effectiveness of a standard versus enhanced version of the replicating effective programs (REP) implementation strategy to improve the uptake of the life goals-collaborative care model (LG-CC) for bipolar disorder. Seven community-based practices (384 patient participants) were randomized to standard (manual/training) or enhanced REP (customized manual/training/facilitation) to promote LG-CC implementation. Participants from enhanced REP sites had no significant changes in primary outcomes (improved quality of life, reduced functioning or mood symptoms) by 24 months. Further research is needed to determine whether implementation strategies can lead to sustained, improved participant outcomes in addition to program uptake.

Social networks, mental health problems, and mental health service utilization in OEF/OIF National Guard veterans

PURPOSE

Low social support and small social network size have been associated with a variety of negative mental health outcomes, while their impact on mental health services use is less clear. To date, few studies have examined these associations in National Guard service members, where frequency of mental health problems is high, social support may come from military as well as other sources, and services use may be suboptimal.

METHODS

Surveys were administered to 1448 recently returned National Guard members. Multivariable regression models assessed the associations between social support characteristics, probable mental health conditions, and service utilization.

RESULTS

In bivariate analyses, large social network size, high social network diversity, high perceived social support, and high military unit support were each associated with lower likelihood of having a probable mental health condition (p < .001). In adjusted analyses, high perceived social support (OR .90, CI .88-.92) and high unit support (OR .96, CI .94-.97) continued to be significantly associated with lower likelihood of mental health conditions. Two social support measures were associated with lower likelihood of receiving mental health services in bivariate analyses, but were not significant in adjusted models.

CONCLUSIONS

General social support and military-specific support were robustly associated with reduced mental health symptoms in National Guard members. Policy makers, military leaders, and clinicians should attend to service members' level of support from both the community and their units and continue efforts to bolster these supports. Other strategies, such as focused outreach, may be needed to bring National Guard members with need into mental health care.

Role of Leadership in Narrowing the Gap between Science and Practice: Improving Treatment Outcomes at the Systems Level

It's been well documented that health care does not reliably transfer what we know from science into clinical practice. As a result, Americans do not always receive the care suggested by the scientific evidence. Despite the best intentions of a dedicated and skilled healthcare workforce, this can often lead to poor clinical outcomes. As research and technology rapidly advance, this gap between science and practice appears to be widening. There is an increasing public concern about a lack of access to appropriate treatment, pervasiveness of unsafe practices, and wasteful uses of precious health care resources leading to suboptimum treatment outcomes. Leadership has a critical role in creating and sustaining the environment that supports health services for individuals and populations that increase the likelihood of desired health outcomes and are consistent with current professional knowledge. Leadership has some responsibility to improve outcomes by insuring effective use of evidence-based treatment guidelines; measurement-based care; knowledge and skills management; care coordination; and information technologies. This paper addresses leadership issues in these components of a system's ability to improve treatment outcomes.

Early identification of treatment non-response utilizing the Patient Health Questionnaire (PHQ-9)

BACKGROUND

Treatment non-response among high-risk, psychiatric patients exposes those suffering to suicidal risk as well as persistent social and occupational difficulties. Strategies for identification of treatment non-response are limited.

AIMS

Diagnostic efficiency of a self-report, cross-cutting symptom measure was assessed as a marker of treatment non-response.

METHOD

835 inpatients at a specialist psychiatric hospital completed the Patient Health Questionnaire - Depression (PHQ-9) at admission and every two weeks during hospitalization.

RESULTS

For patients admitted with severe depression (PHQ-9 ≥ 20), results indicated good accuracy of 2-week PHQ-9 change score in identifying treatment non-response (AUC = 0.80, SE = 0.04, p < .0001; sensitivity = 85%; specificity = 73%; OR = 14.91).

CONCLUSIONS

The search for predictors of non-response to psychiatric treatment has a long and generally unfulfilled history. The PHQ-9 change score holds promise as a cost-effective test with comparable diagnostic characteristics to other medical tests.

A stepped-wedge evaluation of an initiative to spread the collaborative care model for depression in primary care

PURPOSE

Scale-up and spread of evidence-based practices is one of the most important challenges facing health care. We tested whether a statewide initiative, Depression Improvement Across Minnesota-Offering a New Direction (DIAMOND), to implement the collaborative care model for depression in 75 primary care clinics resulted in patient outcome improvements corresponding to those reported in randomized controlled trials.

METHODS

Health plans provided a new monthly payment to participating clinics after a 6-month intensive training program with ongoing data submission, networking, and consultation. Implementation was staggered, with 5 sequences of 10 to 40 clinics every 6 months. Payers provided weekly contact information for members from participating clinics who were filling antidepressant prescriptions, and we conducted baseline and 6-month surveys of 1,578 patients about their care and outcomes.

RESULTS

There were 466 patients in DIAMOND clinics who received usual care before implementation (UCB), 559 who received usual care in DIAMOND clinics after implementation (UCA), 245 who received DIAMOND care after implementation (DCA), and 308 who received usual care in comparison clinics (UC). Patients who received DIAMOND care after implementation reported more collaborative care depression services than the 3 comparison groups (10.9 vs 6.4-6.7, on a scale of 0 of 14, where higher numbers indicate more services; P <.001) and more satisfaction with their care (4.0 vs 3.4 on a scale 1 to 5, in which higher scores indicate higher satisfaction; P ≤.001). Depression remission rates, however, were not significantly different among the 4 groups (36.4% DCA vs 35.8% UCB, 35.0% UCA, 33.9% UC; P = .94).

CONCLUSIONS

Despite the incentive of a supporting payment change and intensive training and support for clinics volunteering to participate, no difference in depression outcomes was documented. Specific unmeasured actions present in trials but not present in these clinics may be critical for successful outcome improvement.

Combining behavioural activation with physical activity promotion for adults with depression: findings of a parallel-group pilot randomised controlled trial (BAcPAc)

BACKGROUND

Depression is associated with physical inactivity, which may mediate the relationship between depression and a range of chronic physical health conditions. However, few interventions have combined a psychological intervention for depression with behaviour change techniques, such as behavioural activation (BA), to promote increased physical activity.

METHODS

To determine procedural and clinical uncertainties to inform a definitive randomised controlled trial (RCT), a pilot parallel-group RCT was undertaken within two Improving Access to Psychological Therapies (IAPT) services in South West England. We aimed to recruit 80 adults with depression and randomise them to a supported, written self-help programme based on either BA or BA plus physical activity promotion (BAcPAc). Data were collected at baseline and 4 months post-randomisation to evaluate trial retention, intervention uptake and variance in outcomes to inform a sample size calculation. Qualitative data were collected from participants and psychological wellbeing practitioners (PWPs) to assess the acceptability and feasibility of the trial methods and the intervention. Routine data were collected to evaluate resource use and cost.

RESULTS

Sixty people with depression were recruited, and a 73 % follow-up rate was achieved. Accelerometer physical activity data were collected for 64 % of those followed. Twenty participants (33 %) attended at least one treatment appointment. Interview data were analysed for 15 participants and 9 study PWPs. The study highlighted the challenges of conducting an RCT within existing IAPT services with high staff turnover and absences, participant scheduling issues, PWP and participant preferences for cognitive focussed treatment, and deviations from BA delivery protocols. The BAcPAc intervention was generally acceptable to patients and PWPs.

CONCLUSIONS

Although recruitment procedures and data collection were challenging, participants generally engaged with the BAcPAc self-help booklets and reported willingness to increase their physical activity. A number of feasibility issues were identified, in particular the under-use of BA as a treatment for depression, the difficulty that PWPs had in adapting their existing procedures for study purposes and the instability of the IAPT PWP workforce. These problems would need to be better understood and resolved before proceeding to a full-scale RCT.

Bayesian restricted spatial regression for examining session features and patient outcomes in open-enrollment group therapy studies

Group-based interventions have been developed for treating patients across a range of health conditions. Enrollment into such groups often occurs on an open (or rolling) basis. Conditional autoregression modeling of random session effects has been proposed to account for the expected correlation in session effects associated with the overlap in patient participation session to session. However, when the analytic objective is to examine the relationship between a fixed-effect session feature and a patient outcome using conditional autoregression, confounding might arise if the fixed session feature of interest and the random session effects vary across sessions in similar ways, resulting in bias and inflated standard errors of a fixed-effect session feature of interest. Motivated by the goal of examining the relationships between outcomes and the session features of leader and session module theme, we applied restricted spatial regression to the analysis of patient outcomes collected from 132 participants in an open-enrollment group for treating depression among patients of a residential alcohol and other drug treatment program, adapting the approach to the multilevel data structure of open-enrollment group data. As compared with standard conditional autoregression, the restricted regression approach resulted in more precise estimates of regression coefficients of the module theme and leader predictor variables. The restricted regression approach provides an important analytic tool for group therapy researchers who are investigating the relationship between key components of open-enrollment group therapy interventions and patient outcomes.

Does an outreaching stepped care program reduce depressive symptoms in community-dwelling older adults? A randomized implementation trial

OBJECTIVES

To examine the effects of an outreaching stepped care intervention program (Lust for Life) compared with usual care on depressive symptoms in older adults living in the community.

DESIGN

Randomized clinical implementation trial.

SETTING

18 general practices and a home care organization in the Netherlands.

PARTICIPANTS

263 community-dwelling 65+-year-olds with depressive symptoms according to the Patient Health Questionnaire-9 (PHQ-9).

INTERVENTION

After three months of watchful waiting, participants could sequentially choose between the following evidence-based interventions: 1) guided self-help or an exercise program, 2) problem solving treatment or life review, and 3) a referral to their general practitioner.

MEASUREMENTS

The outcome measure was depression severity (PHQ-9), measured every three months over 2 years.

RESULTS

After the provision of the stepped care program, a significant short-term positive effect on depressive symptoms was found in the first three months after implementation, in which average PHQ-9 scores dropped from 9.34 (SE: 0.61, 95% CI: 8.14-10.5) to 7.83 (SE: 0.51, 95% CI: 6.84-8.81).

CONCLUSIONS

The Lust for Life program has a promising potential to relieve depressive symptoms of older adults in primary care in the short term. Providing one single clinical intervention in accordance with participants' choices instead of stepped care could be sufficient.

Adding smartphone-based cognitive-behavior therapy to pharmacotherapy for major depression (FLATT project): study protocol for a randomized controlled trial

Background

Major depression is one of the most debilitating diseases in terms of quality of life. Less than half of patients suffering from depression can achieve remission after adequate antidepressant treatment. Another promising treatment option is cognitive-behavior therapy (CBT). However, the need for experienced therapists and substantive dedicated time prevent CBT from being widely disseminated.

In the present study, we aim to examine the effectiveness of switching antidepressants and starting a smartphone-based CBT program at the same time, in comparison to switching antidepressants only, among patients still suffering from depression after adequate antidepressant treatment.

Methods/design

A multi-center randomized trial is currently being conducted since September 2014. The smartphone-based CBT program, named the “Kokoro-App,” for major depression has been developed and its feasibility has been confirmed in a previous open study. The program consists of an introduction, 6 sessions and an epilogue, and is expected to be completed within 9 weeks by patients. In the present trial, 164 patients with DSM-5 major depressive disorder and still suffering from depressive symptoms after adequate antidepressant treatment for more than 4 weeks will be allocated to the Kokoro-App plus switching antidepressant group or the switching antidepressant alone group. The participants allocated to the latter group will receive full components of the Kokoro-App after 9 weeks.

The primary outcome is the change in the total score on the Patient Health Questionnaire through the 9 weeks of the program, as assessed at week 0, 1, 5 and 9 via telephone by blinded raters. The secondary outcomes include the change in the total score of the Beck Depression Inventory-II, change in side effects as assessed by the Frequency, Intensity and Burden of Side Effects Rating, and treatment satisfaction.

Discussion

An effective and reachable intervention may not only lead to healthier mental status among depressed patients, but also to reduced social burden from this illness. This paper outlines the background and methods of a trial that evaluates the possible additive value of a smartphone-based CBT program for treatment-resistant depression.

Presurgical assessment of bariatric patients with the Patient Health Questionnaire (PHQ)--a screening of the prevalence of psychosocial comorbidity

BACKGROUND

Bariatric surgery has gained increasing relevance due to the dramatic rise in morbid obesity prevalence. A sound body of scientific literature demonstrates positive long-term outcome of bariatric surgery in decreasing mental and physical health morbidity. Still, there is a need for a manageable presurgical screening to assess major mental disorders. The aim of this study was to assess the frequency of common psychiatric syndromes in bariatric surgery candidates using a computerized version of the Patient Health Questionnaire (PHQ).

METHODS

In a prospective cohort study from August 2009 to July 2011 morbidly obese individuals seeking bariatric treatment were evaluated for mental health disorders using the PHQ (computerized German version).

RESULTS

A total of 159 patients were included in this study. The median age of participants was 42 years, the median BMI was 49 kg/m(2). The PHQ revealed a prevalence of 84 % for mental health disorders, 50 % of the participants had three or more mental health disorders. A high somatic symptom burden (46 %), depressive syndromes (62 %) and anxiety disorders (29 %) were the most frequent psychiatric syndromes. The median number of psychiatric syndromes was 3 for women and 1 for men (p = 0.007). No correlation between BMI and a single syndrome or the sum of syndromes was observed.

CONCLUSION

84 % of the patients seeking bariatric treatment were screened positive for at least one mental health disorder. The computerized PHQ with automated reporting appears to be a useful instrument for presurgical assessment of bariatric patients in routine medical settings.

Rasch validation of the PHQ-9 in people with visual impairment in South India

BACKGROUND

The Patient-Health Questionnaire (PHQ-9) is a widely used screening instrument for depression. Recently, its properties as a measure were investigated using Rasch analysis in an Australian population with visual impairment (VI) and it was demonstrated to possess excellent measurement properties, but the response scale required shortening (modified PHQ-9). However, further validation was recommended to substantiate its use with the growing population of VI. Therefore, we aimed to use Rasch analysis to evaluate the measurement properties of the modified PHQ-9 in an Indian population with VI.

METHODS

303 patients with VI (mean age 40.2 years; 71% male) referred to Vision Rehabilitation Centres were administered the PHQ-9 by trained interviewer. Rasch analysis was used to investigate the psychometric properties of the modified PHQ-9.

RESULTS

Rasch analysis showed good fit to the model, no misfitting items and an acceptable person separation reliability (0.82). Dimensionality testing supported combining 9 items to create a total score. Targeting was sub-optimal (-1.30 logits); more difficult items are needed. One item ('trouble falling asleep') showed notable differential item functioning, DIF (1.18 logits) by duration of VI.

LIMITATIONS

The generalisability of these results might be restricted to patients with VI presenting to a tertiary eye care centre.

CONCLUSIONS

Except for DIF, the performance of the modified PHQ-9 is consistent with that of the original, albeit in a different cultural context (Indian population with VI). Clinicians/researchers can readily use the modified PHQ-9 without formal training in Rasch procedures given the provision of ready-to-use spreadsheets that convert raw to Rasch-scaled scores. However the conversions will apply only if the sample being tested is similar to that of the present study.

The Beyond Ageing Project Phase 2--a double-blind, selective prevention, randomised, placebo-controlled trial of omega-3 fatty acids and sertraline in an older age cohort at risk for depression: study protocol for a randomized controlled trial

BACKGROUND

Late-life depression is associated with high rates of morbidity, premature mortality, disability, functional decline, caregiver burden and increased health care costs. While clinical and public health approaches are focused on prevention or early intervention strategies, the ideal method of intervention remains unclear. No study has set out to evaluate the role of neurobiological agents in preventing depressive symptoms in older populations at risk of depression.

METHODS/DESIGN

Subjects with previously reported sub-threshold depressive symptoms, aged 60 to 74 years, will be screened to participate in a single-centre, double-blind, randomised controlled trial with three parallel groups involving omega-3 fatty acid supplementation or sertraline hydrochloride, compared with matching placebo. Subjects will be excluded if they have current depression or suicide ideation; are taking antidepressants or any supplement containing omega-3 fatty acid; or have a prior history of stroke or other serious cerebrovascular or cardiovascular disease, neurological disease, significant psychiatric disease (other than depression) or neurodegenerative disease. The trial will consist of a 12 month treatment phase with follow-up at three months and 12 months to assess outcome events. At three months, subjects will undergo structural neuroimaging to assess whether treatment effects on depressive symptoms correlate with brain changes. Additionally, proton spectroscopy techniques will be used to capture brain-imaging markers of the biological effects of the interventions. The trial will be conducted in urban New South Wales, Australia, and will recruit a community-based sample of 450 adults. Using intention-to-treat methods, the primary endpoint is an absence of clinically relevant depression scores at 12 months between the omega-3 fatty acid and sertraline interventions and the placebo condition.

DISCUSSION

The current health, social and economic costs of late-life depression make prevention imperative from a public health perspective. This innovative trial aims to address the long-neglected area of prevention of depression in older adults. The interventions are targeted to the pathophysiology of disease, and regardless of the effect size of treatment, the outcomes will offer major scientific advances regarding the neurobiological action of these agents. The main results are expected to be available in 2017.

Psychological and interactional characteristics of patients with somatoform disorders: Validation of the Somatic Symptoms Experiences Questionnaire (SSEQ) in a clinical psychosomatic population

OBJECTIVE

The new DSM-5 Somatic Symptom Disorder (SSD) emphasizes the importance of psychological processes related to somatic symptoms in patients with somatoform disorders. To address this, the Somatic Symptoms Experiences Questionnaire (SSEQ), the first self-report scale that assesses a broad range of psychological and interactional characteristics relevant to patients with a somatoform disorder or SSD, was developed. This prospective study was conducted to validate the SSEQ.

METHODS

The 15-item SSEQ was administered along with a battery of self-report questionnaires to psychosomatic inpatients. Patients were assessed with the Structured Clinical Interview for DSM-IV to confirm a somatoform, depressive, or anxiety disorder. Confirmatory factor analyses, tests of internal consistency and tests of validity were performed.

RESULTS

Patients (n=262) with a mean age of 43.4 years, 60.3% women, were included in the analyses. The previously observed four-factor model was replicated and internal consistency was good (Cronbach's α=.90). Patients with a somatoform disorder had significantly higher scores on the SSEQ (t=4.24, p<.001) than patients with a depressive/anxiety disorder. Construct validity was shown by high correlations with other instruments measuring related constructs. Hierarchical multiple regression analyses showed that the questionnaire predicted health-related quality of life. Sensitivity to change was shown by significantly higher effect sizes of the SSEQ change scores for improved patients than for patients without improvement.

CONCLUSION

The SSEQ appears to be a reliable, valid, and efficient instrument to assess a broad range of psychological and interactional features related to the experience of somatic symptoms.

Inner resources for survival: integrating interpersonal psychotherapy with spiritual visualization with homeless youth

Homeless youth have particular need to develop inner resources to confront the stress, abusive environment of street life, and the paucity of external resources. Research suggests that treatment supporting spiritual awareness and growth may create a foundation for coping, relationships, and negotiating styles to mitigate distress. The current pilot study tests the feasibility, acceptability, and helpfulness of an interpersonal spiritual group psychotherapy, interpersonal psychotherapy (IPT) integrated with spiritual visualization (SV), offered through a homeless shelter, toward improving interpersonal coping and ameliorating symptoms of depression, distress, and anxiety in homeless youth. An exploratory pilot of integrative group psychotherapy (IPT + SV) for homeless young adults was conducted in a New York City on the residential floor of a shelter-based transitional living program. Thirteen young adult men (mean age 20.3 years, SD = 1.06) participated in a weekly evening psychotherapy group (55 % African-American, 18 % biracial, 18 % Hispanic, 9 % Caucasian). Measures of psychological functioning were assessed at pre-intervention and post-intervention using the General Health Questionnaire (GHQ-12), Patient Health Questionnaire (PHQ-9, GAD-7), and the Inventory of Interpersonal Problems (IIP-32). A semi-structured exit interview and a treatment satisfaction questionnaire were also employed to assess acceptability following treatment. Among homeless young adults to participate in the group treatment, significant decreases in symptoms of general distress and depression were found between baseline and termination of treatment, and at the level of a trend, improvement in overall interpersonal functioning and levels of general anxiety. High utilization and treatment satisfaction showed the intervention to be both feasible and acceptable. Offered as an adjunct to the services-as-usual model at homeless shelters serving young adults, interpersonal psychotherapy with spiritual visualization (IPT + SV) in group appears to be a feasible and potentially useful treatment option for promoting improved mental health.

Return-to-Work Self-Efficacy and Actual Return to Work Among Long-Term Sick-Listed Employees

OBJECTIVE

Considering the costs incurred by sickness absence and the implications for the workers' quality of life, a fast return to work (RTW) is important. Self-efficacy (SE) seems to be an important predictor of RTW for employees with mental health problems. The predictive value of return-to-work self-efficacy (RTW-SE) has not been examined in employees on long-term sickness absence due to any cause. The aim of this study is to investigate whether RTW-SE is a predictor of time to RTW in long-term sick-listed employees with all-cause sickness absence. Furthermore, the relative contribution of RTW-SE in predicting RTW will be examined compared to health-related, job-related and personal factors.

METHODS

In a longitudinal study, sick-listed employees who were currently on sick leave for more than 4 weeks filled out a self-report questionnaire. Demographics, health-related, personal, and job-related factors, and RTW-SE were measured. Employees were followed for 2 years to determine the duration until full RTW. Cox proportional hazards regression analyses were used to identify factors associated with time to RTW.

RESULTS

Data were collected from 493 sick-listed employees. RTW-SE was a significant predictor of RTW. In a multivariate model, low RTW-SE, the thought of not being able to work while having symptoms (illness behaviour) and having chronic medical conditions were predictors of a longer duration until RTW.

CONCLUSION

When guiding long-term sick-listed employees, it is important to focus on factors such as SE and illness behaviour, instead of just focusing on the symptoms of the sick-listed employee.

A randomized trial of a depression self-care toolkit with or without lay telephone coaching for primary care patients with chronic physical conditions

OBJECTIVE

The aim of this study was to compare outcomes of use of a depression self-care toolkit with and without lay telephone coaching among primary care patients 40 years and older with depressive symptoms and comorbid chronic physical conditions.

METHOD

A single blind, individually randomized, pragmatic trial of a depression self-care toolkit (Toolkit) with or without lay telephone coaching was conducted among primary care adults with depressive symptoms and comorbid chronic physical conditions. Eligible patients were randomized to receive the Toolkit with (intervention) or without (control) telephone coaching provided by trained lay coaches. The primary outcome was depression severity [Patient Health Questionnaire (PHQ-9)] at 6 months. Secondary outcomes were self-efficacy, satisfaction, and use of health services at 6 months.

RESULTS

A total of 223 patients were randomized, and 172 (77.1%) completed 6-month follow-ups. PHQ-9 scores improved significantly in both groups over the 6-month follow-up; the differences in PHQ-9 scores between intervention and control groups were statistically significant at 3 months [effect size = 0.44; 95% confidence interval (CI) = 0.16-0.72] but not at 6 months (effect size = 0.24; 95% CI = -0.01 to 0.60). Patients with moderate depression severity (PHQ-9 10-19) and high self-efficacy at baseline were most likely to benefit from the intervention. There was no significant effect of the intervention on the secondary outcomes.

CONCLUSIONS

The incremental value of lay telephone coaching of a Toolkit appears short-lived. Targeting of coaching to those with moderate depression severity may be indicated.

A neurobehavioral account for individual differences in resilience to chronic military stress

BACKGROUND

Military training is a chronic stressful period that often induces stress-related psychopathology. Stress vulnerability and resilience depend on personality trait anxiety, attentional threat bias and prefrontal-limbic dysfunction. However, how these neurobehavioral elements interact with regard to the development of symptoms following stress remains unclear.

METHOD

Fifty-five healthy combat soldiers undergoing intensive military training completed functional magnetic resonance imaging (fMRI) testing while performing the dot-probe task (DPT) composed of angry (threat) and neutral faces. Participants were then stratified according to their bias tendency to avoidance (n = 25) or vigilance (n = 30) groups, categorized as high or low trait anxiety and assessed for post-stress symptom severity.

RESULTS

Avoidance compared to vigilance tendency was associated with fewer post-trauma symptoms and increased hippocampal response to threat among high anxious but not low anxious individuals. Importantly, mediation analysis revealed that only among high anxious individuals did hippocampal activity lead to lower levels of symptoms through avoidance bias tendency. However, in the whole group, avoidance bias was modulated by the interplay between the hippocampus and the dorsal anterior cingulate cortex (dACC).

CONCLUSIONS

Our results provide a neurobehavioral model to explain the resilience to post-trauma symptoms following chronic exposure. The model points to the importance of considering threat bias tendency in addition to personality traits when investigating the brain response and symptoms of trauma. Such a multi-parametric approach that accounts for individual behavioral sensitivities may also improve brain-driven treatments of anxiety, possibly by targeting the interplay between the hippocampus and the dACC.

Psychenet.de: Development and process evaluation of an e-mental health portal

BACKGROUND

E-mental health interventions can have a positive impact on patient-reported and clinical outcomes. The purpose of this project was to develop a user-centered e-mental health portal.

METHODS

The development of the portal www.psychenet.de included mixed-methods techniques for needs assessment to identify user-relevant content. Furthermore, user-centered design techniques were applied by utilizing individual usability testing with cognitive task analysis. First, a basic version of the portal was created and introduced to the public by means of a media campaign. After the development of module-specific content, exposure and use of the portal was investigated as part of a process evaluation.

RESULTS

Relevant content identified by needs assessment covered both, overarching and diagnosis-specific topics. Results of the process evaluation showed a highly accessed website. During the first 18 months, 119,423 visits were tracked. The portal was predominantly accessed by Google searches (73.9%), while 17.6% of visits were related to direct traffic.

DISCUSSION

Serving as a complement to face-to-face consultations, www.psychenet.de attempts to inform about mental disorders, and engage patients in the course of their treatment. Results of the process evaluation confirm the high relevance and potential of the portal and can be used for further improvements and extensions in the future.

Preventing eating disorders with an interactive gender-adapted intervention program in schools: study protocol of a randomized controlled trial

BACKGROUND

There are a high number of adolescents who are at risk of developing an eating disorder. There is, therefore, a strong need to implement prevention programs aimed at reducing the incidence of eating disorders at this critical age. Among other factors, successful prevention programs have been shown to be interactive, carried out by professionals, focused on educational as well as psychosocial elements and have taken risk factors as well as resources into account. The objective of this study protocol is to present the design of a new prevention program for eating disorders in schools.

METHODS/DESIGN

The gender-adapted prevention program extends over six school hours. It contains interactive and educational elements about eating disorders and their treatment. Participants pass through different exercises and reflect on the influences of the media, self-esteem, body perception and individual resources. A cluster-randomized controlled trial is chosen to evaluate the program. Based on an estimated effect size of d = 0.3 a total of 1848 participants are enrolled in the study. Eating disorder risk, internalization of Western beauty ideals, body dissatisfaction, self-concept as well as anxiety and symptoms of depression are measured before and immediately after the intervention as well as at a six-month follow-up. In addition, the intervention group evaluates the different components of the program.

DISCUSSION

The study intends to test the practicability and efficacy of an interactive, gender-adapted ED prevention program in schools. Moreover, it will provide valuable information about the occurrence of eating disorder risk factors in school-aged children.

Free, brief, and validated: Standardized instruments for low-resource mental health settings

Evidence-based assessment has received little attention despite its critical importance to the evidence-based practice movement. Given the limited resources in the public sector, it is necessary for evidence-based assessment to utilize tools with established reliability and validity metrics that are free, easily accessible, and brief. We review tools that meet these criteria for youth and adult mental health for the most prevalent mental health disorders to provide a clinical guide and reference for the selection of assessment tools for public sector settings. We also discuss recommendations for how to move forward the evidence-based assessment agenda.

Seasonal variation in clinical remission of primary care patients with depression: impact of gender

RATIONALE, AIMS AND OBJECTIVES

The impact of seasonal variation on clinical remission in patients with depression has not been well studied. The hypothesis for this study was that the clinical remission rate would be lower in the winter comparing to the other seasons, specifically evaluated by gender.

METHODS

The study cohort comprised 2873 primary care patients with depression as a longitudinal retrospective chart review analysis. The sample was limited to patients who were continuing in care; dropouts were excluded from the analysis.

RESULTS

Multivariate logistic regression analysis of the independent variables for those participants who achieved clinical remission demonstrated that for the male patients, the season of diagnosis did not impact the rate of remission at 6 months while controlling for all other independent variables. For female patients, those that were diagnosed with depression in the fall had increased likelihood of 6-month remission compared with those patients diagnosed in the winter months (OR 1.300, CI 1.006-1.680, P=0.045) and the spring and summer patients were not significantly different in their outcome rates. When both genders were combined, the odds of remission at 6 months were not statistically significant for any season of diagnosis.

CONCLUSIONS

This study demonstrates that in patients who were continuing care, women who were diagnosed with major depression or dysthymia in the fall season have improved 6-month clinical outcome of remission compared with those women diagnosed in the winter, when controlling for demographic and clinical characteristics. This effect was not seen in men or when the genders were combined into a single cohort. The assessment of the seasonality effect on depression outcomes requires further long-term follow-up studies.

Surgical assessment: measuring unobserved health

Background

The federal and provincial governments in Canada have invested an enormous amount of resources to measure, report and reduce surgical wait times. Yet these measures under-report the wait period that patients’ actually experience, because they do not capture the length of time a patient spends waiting to see the surgeon for a surgical assessment. This unmeasured time is referred to as the “wait one” (W1). Little is known about W1 and the effects that this has on patients’ health. Similarly, it is not understood whether patients waiting for surgical assessment actually want or need surgery. Existing administrative and clinical dataset do not capture information on health and decision-making while the patient is waiting for care form a specialist. The objective of this proposed study is to understand the impact that W1 for elective surgeries has on the health of patients and to determine whether this time can be reduced.

Methods/Design

A prospective survey design will be used to measure the health of patients waiting for surgical assessment. Working with the support of the surgical specialities in Vancouver Coastal Health, we will survey patients immediately after being referred for surgical assessment, and every four months thereafter, until they are seen by the surgeon.

Validated survey instruments will be used, including: generic and condition-specific health status questionnaires, pain and depression assessments. Other factors that will be measured include: patients’ knowledge about their condition, and their desired autonomy in the decision making process. We have piloted data collection in one surgical specialty in order to demonstrate feasibility.

Discussion

The results from this study will be used to quantify changes in patients’ health while they wait for surgical assessment. Based on this, policy- and decision-makers could design care interventions during W1, aimed at mitigating any negative health consequences associated with waiting. The results from this study will also be used to better understand whether there are factors that predict patients’ desire to proceed to surgery. These could be used to guide future research into experimenting with interventions to minimize inappropriate referrals and where they are best targeted.

Combat high or traumatic stress: violent offending is associated with appetitive aggression but not with symptoms of traumatic stress

Former members of armed groups in eastern DR Congo had typically witnessed, experienced, and perpetrated extreme forms of violence. Enhanced trauma-related symptoms had been shown in prior research. But also lashing out in self-defense is a familiar response to threat defined as reactive aggression. Another potential response is appetitive aggression, in which the perpetration of excessive violence is perceived as pleasurable (combat high). What roles do these forms of aggressive behavior play in modern warfare and how are they related to posttraumatic stress symptoms? To answer the question, we sought to determine predictors for appetitive aggressive and trauma-related mental illness, and investigated the frequency of psychopathological symptoms for high- and low-intensity conflict demobilization settings. To this end, we interviewed 213 former members of (para)military groups in the eastern Democratic Republic of Congo in regard to their combat exposure, posttraumatic stress, appetitive aggression, depression, suicidality, and drug dependence. Random forest regression embedded in a conditional inference framework revealed that perpetrated violent acts are not necessarily stressful. In fact, the experience of violent acts that typically implicated salient cues of hunting (e.g., blood, suffering of the victim, etc.) had the strongest association with an appetite for aggression. Furthermore, the number of lifetime perpetrated violent acts was the most important predictor of appetitive aggression. However, the number of perpetrated violent acts did not significantly affect the posttraumatic stress. Greater intensity of conflict was associated with more severe posttraumatic stress symptoms and depression. Psychotherapeutic interventions that address appetitive aggression in addition to trauma-related mental illness, including drug dependence, therefore seem indispensible for a successful reintegration of those who fought in the current civil wars.

The impact of preoperative depression on quality of life outcomes after lumbar surgery

BACKGROUND CONTEXT

Some, smaller studies have investigated the effect of preoperative depression on postoperative improvement in quality of life (QOL). However, they have not used the Patient Health Questionnaire 9 (PHQ-9) in self-reported depression.

PURPOSE

To assess the effect of preoperative depression as measured by the PHQ-9 on postoperative improvement in QOL.

STUDY DESIGN

A retrospective review at a single tertiary-care referral center.

PATIENT SAMPLE

Patients who underwent lumbar decompression or fusion between 2008 and 2012.

OUTCOMES MEASURES

A self-reported EuroQol five-dimensions (EQ-5D) quality-adjusted life-years Index.

METHODS

Quality of life data were collected using the institutional prospectively collected database of patient-reported health status measures. The EQ-5D questionnare, PDQ, and PHQ-9 were used. Linear and logistic regression analyses were performed to assess the impact of preoperative depression on QOL improvement.

RESULTS

Elevated preoperative pain (PDQ, β=-0.0017, p=.0009) and worsened depression (PHQ-9, β=-0.0044, p=.0359) were significantly associated with diminished postoperative improvement in QOL, as measured by the EQ-5D. Furthermore, greater depression (PHQ-9, odds ratio [OR] 0.93, p<.0001) and pain (PDQ, OR 0.99, p=.02) were associated with significantly diminished postoperative improvement exceeding the minimum clinically important difference.

CONCLUSIONS

Increased preoperative pain and depression were shown to be associated with significantly reduced improvement in postoperative QOL, as measured by the EQ-5D.

A randomized trial of collaborative depression care in obstetrics and gynecology clinics: socioeconomic disadvantage and treatment response

OBJECTIVE

The authors evaluated whether an obstetrics-gynecology clinic-based collaborative depression care intervention is differentially effective compared with usual care for socially disadvantaged women with either no health insurance or with public coverage compared with those with commercial insurance.

METHOD

The study was a two-site randomized controlled trial with an 18-month follow-up. Women were recruited who screened positive (a score of at least 10 on the Patient Health Questionnaire-9) and met criteria for major depression or dysthymia. The authors tested whether insurance status had a differential effect on continuous depression outcomes between the intervention and usual care over 18 months. They also assessed differences between the intervention and usual care in quality of depression care and dichotomous clinical outcomes (a decrease of at least 50% in depressive symptom severity and patient-rated improvement on the Patient Global Improvement Scale).

RESULTS

The treatment effect was significantly associated with insurance status. Compared with patients with commercial insurance, those with no insurance or with public coverage had greater recovery from depression symptoms with collaborative care than with usual care over the 18-month follow-up period. At the 12-month follow-up, the effect size for depression improvement compared with usual care among women with no insurance or with public coverage was 0.81 (95% CI=0.41, 0.95), whereas it was 0.39 (95% CI=-0.08, 0.84) for women with commercial insurance.

CONCLUSIONS

Collaborative depression care adapted to obstetrics-gynecology settings had a greater impact on depression outcomes for socially disadvantaged women with no insurance or with public coverage compared with women with commercial insurance.
