Measuring trauma and stressful events in childhood and adolescence among patients with first-episode psychosis: initial factor structure, reliability, and validity of the Trauma Experiences Checklist

Review of Major Social Determinants of Health in Schizophrenia-Spectrum Disorders: II. Assessments

BACKGROUND AND AIMS

Social determinants of health (SDoHs) impact the development and course of schizophrenia-spectrum psychotic disorders (SSPDs). Yet, we found no published scholarly reviews of psychometric properties and pragmatic utility of SDoH assessments among people with SSPDs. We aim to review those aspects of SDoH assessments.

STUDY DESIGN

PsychInfo, PubMed, and Google Scholar databases were examined to obtain data on reliability, validity, administration process, strengths, and limitations of the measures for SDoHs identified in a paired scoping review.

STUDY RESULTS

SDoHs were assessed using different approaches including self-reports, interviews, rating scales, and review of public databases. Of the major SDoHs, early-life adversities, social disconnection, racism, social fragmentation, and food insecurity had measures with satisfactory psychometric properties. Internal consistency reliabilities-evaluated in the general population for 13 measures of early-life adversities, social disconnection, racism, social fragmentation, and food insecurity-ranged from poor to excellent (0.68-0.96). The number of items varied from 1 to more than 100 and administration time ranged from less than 5 minutes to over an hour. Measures of urbanicity, low socioeconomic status, immigration status, homelessness/housing instability, and incarceration were based on public records or targeted sampling.

CONCLUSIONS

Although the reported assessments of SDoHs show promise, there is a need to develop and test brief but validated screening measures suitable for clinical application. Novel assessment tools, including objective assessments at individual and community levels utilizing new technology, and sophisticated psychometric evaluations for reliability, validity, and sensitivity to change with effective interventions are recommended, and suggestions for training curricula are offered.

Experiences of Sexual Harassment by Patients among Nurses at the Mental Hospital of West Java Province: A Qualitative Study

Sexual harassment is behavior related to forced sex without the consent of the victim. Incidents of sexual harassment on nurses can be in the form of physical behavior and verbal behavior. The factor of power relations between men and women and the patriarchal culture in Indonesia are the causes of the sexual harassment of mental health nurses, so many incidents of the sexual harassment of women occur. The forms of sexual harassment that occur include kissing, hugging from behind, and verbal abuse related to sex. The purpose of this study was to explore the experience of sexual harassment of psychiatric nurses at the Mental Hospital of West Java Province. This study implemented a qualitative descriptive approach using the NVIVO 12 software application. The sample in this study was 40 psychiatric nurses at the Mental Hospital of West Java Province. The sampling technique in this study was focus group discussions with semi-structured and in-depth interviews. The data analysis in this study used a thematic analysis. This study shows that sexual harassment behavior is carried out by patients in physical and verbal forms. Sexual harassment is mostly carried out by male patients towards female nurses. Meanwhile, sexual harassment took the form of hugging from behind, kissing, naked patients in front of nurses, and disturbing nurses with verbal abuse related to sex. Nurses feel disturbed, afraid, anxious, and shocked by the incidents of sexual harassment committed by patients. Sexual harassment by patients towards nurses causes psychological problems for nurses and causes nurses to want to leave their jobs. Gender adjustment between nurses and patients is a preventive effort to prevent the sexual harassment of nurses. Sexual harassment by patients causes a decrease in the quality of work of nurses in providing nursing care, creating a work environment that is less safe and comfortable.

Trauma measures for use with psychosis populations: A systematic review of psychometric properties using COSMIN

Traumatic events play a key role in the development and course of psychosis. Psychotic symptoms themselves and coercive treatment practices can be inherently traumatic. Hence, reliable and valid methods of assessing trauma and its impact (i.e., Post-Traumatic Stress Disorder (PTSD) symptomology) are essential for use with people with psychosis. Many measures are available to select from, but this is the first review to appraise the psychometric properties of trauma measures to guide decision making regarding instrument use. The review was prospectively registered on Prospero (CRD42022306100). Evaluation of methodological and psychometric quality followed Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidance. Twenty-four articles were eligible, with sixteen trauma measures evaluated. Childhood Trauma Questionnaire- Short Form demonstrated the most robust evidence for assessing experience of trauma. The Trauma and Life Experience (TALE) checklist was the only measure to include specific psychosis and iatrogenic harm items. For PTSD measures, the Symptoms of Trauma Scale and PTSD Symptom Scale- Self Report had the highest quality evidence. Psychometric strengths and weaknesses of various trauma measures are comprehensively evaluated, highlighting future research directions to strengthen the evidence base with emphasis on further evaluation of the TALE, which integrates trauma specific to psychosis.

Childhood maltreatment increases the suicidal risk in Chinese schizophrenia patients

OBJECTIVES

Childhood trauma might be a modifiable risk factor among adults with serious mental illness. However, the correlation of child trauma and suicide is unclear, which were cited most frequently as the biggest challenge to schizophrenia (SCZ) patients in China. We aim to study relationships between child trauma and suicide in SCZ patients of different disease stages.

METHODS

Ninety-one participants were included and divided into two groups, namely, first-episode group (n = 46), relapsed group (n = 45). The Positive and Negative Syndrome Scale was used to evaluate the severity of psychotic symptoms. The Beck's Suicide Intent Scale and The Nurses' Global Assessment of Suicide Risk were conducted by patient self-report to assess suicide symptom. The childhood trauma questionnaire was used to estimate severity of traumatic stress experienced during childhood.

RESULTS

Childhood trauma and different dimensions of suicide were significantly higher in the relapsed group than first-episode group (P < 0.01, respectively). BMI has a significant positive relationship with recent psychosocial stress (β = 0.473, t = 3.521, P < 0.001) in first-episode group. As in relapsed group, BMI has a positive effect between severe mental illness and suicide ideation (β = 0.672, t = 5.949, P < 0.001; β = 0.909, t = 2.463, P < 0.001), Furthermore, emotional neglect presented positively related to the suicide risk and proneness to suicidal behavior (β = 0.618, t = 5.518, P < 0.001; β = 0.809, t = 5.356, P < 0.001).

CONCLUSION

Relapsed group of patients had significantly more severe childhood trauma, recent psychosocial stress, suicidal risk and proneness to suicidal behavior. BMI and emotional neglect are unique predictors for different dimensions of suicide.

Adversity in childhood/adolescence and premorbid tobacco, alcohol, and cannabis use among first-episode psychosis patients

AIM

Premorbid substance use is widely recognized as a crucial factor in early psychosis. We explored the effects of childhood/adolescent adversity on premorbid tobacco, alcohol, and cannabis use. We hypothesized that adversity in childhood would be associated with an increased likelihood of use, and amount of intake, of tobacco, alcohol, and cannabis. We analysed which domains of adversity have the greatest impact.

METHODS

First-episode psychosis patients were enrolled from six inpatient psychiatric units in Atlanta, Georgia and Washington, D.C. Premorbid substance use was thoroughly measured, and childhood/adolescent adversity was rated using 14 scales/subscales. Factor analysis was used to reduce these scales/subscales to the three domains of adversity (termed Violence and Environmental Adversity, Interpersonal Abuse, and Neglect and Lack of Connectedness). Regression analyses determined associations between adversity domains and premorbid substance use.

RESULTS

Our sample (n = 247) primarily consisted of African Americans (86.2%) and males (74.5%). Violence and Environmental Adversity was significantly associated with five of six substance use variables and marginally associated with the sixth. Interpersonal Abuse was unassociated with substance use, and Neglect and Lack of Connectedness was associated only with a lower likelihood cannabis use. When Violence and Environmental Adversity results were stratified by gender, effects on tobacco use and amount of tobacco use were stronger among females.

CONCLUSIONS

Childhood/adolescent trauma and adversity have meaningful associations with premorbid substance use in first-episode psychosis patients. First-episode psychosis and clinical high-risk treatment settings may benefit from expanding the assessment of childhood/adolescent adversity to include factors pertaining to violence exposure and adversities beyond abuse and neglect.

Attention-deficit/hyperactivity disorder has a state-dependent association with asthma: The role of systemic inflammation in a population-based birth cohort followed from childhood to adulthood

There is a high comorbidity between attention-deficit/hyperactivity disorder (ADHD) and asthma, and inflammation has been proposed as a potential pathophysiological mechanism behind this association. Most studies conducted so far have used a cross-sectional design, and none has evaluated the prevalence of asthma symptoms in patients with ADHD followed from childhood to adulthood. We relied on data from the 1993 Pelotas birth cohort to evaluate the association between ADHD and asthma in patients with distinct patterns of incidence, persistence and remission, and to explore the potential role of inflammatory markers in the comorbidity. We analyzed data from 3281 individuals from the 1993 Pelotas birth cohort collected at birth (1993), 11 years (2004), 18 years (2011), and 22 years (2015). Subjects were first classified according to their ADHD and asthma status as early-onset (EO) persistent (positive screening for ADHD at 11 years and diagnosis of ADHD according to DSM-5, except criterion E, at either 18 or 22 years), EO-remittent (positive screening for ADHD at 11 years only), late-onset (diagnosis of ADHD according to DSM-5, except criterion E, at 18 or 22 years only), or healthy subjects (negative for both conditions in all evaluation). After controlling for confounders, significant associations were observed between EO-remittent ADHD and EO-remittent asthma (OR 1.68, 95% CI 1.11-2.55), EO-persistent ADHD and EO-persistent asthma (OR 4.33, 95% CI 1.65-11.34), and between late-onset ADHD and late-onset asthma (OR 1.86, 95% CI 1.28-2.70), suggesting a state-dependent association. Serum interleukin-6 (IL-6) and C-reactive protein (CRP) were measured at the 18- and 22-year evaluations and compared between subjects positive for ADHD, asthma, and subjects with both or none conditions, regardless of the previously defined trajectories. Subjects with comorbid ADHD and asthma presented higher levels of IL-6 at the 18- and 22-year evaluations when compared to subjects negative for both conditions. Our results demonstrate a state-dependent association between ADHD and asthma despite underlying trajectories. Higher levels of serum IL-6 in patients with both conditions suggest that a pro-inflammatory environment might have a role in the pathophysiological mechanisms underlying the comorbidity.

Associations Between Childhood and Adolescence Adversity and Risk for Arrest Among Patients With First-Episode Psychosis

OBJECTIVE

The authors assessed associations between childhood and adolescent adversity and arrest among individuals with first-episode psychosis (FEP). The authors also sought to determine which domains of adversity had the greatest impact and whether associations varied by gender.

METHODS

Data were analyzed from 247 patients with FEP admitted to inpatient psychiatric units between August 2008 and June 2013. Analyses focused on self-reported history of arrest and seven scales of past adversity, with 14 subscales reduced to three factors. Binary logistic regression and negative binomial regression determined associations between the three childhood adversity factors and having ever been arrested and number of arrests, respectively.

RESULTS

Past experience of violence and environmental adversity was significantly (p<0.001) associated with both history of arrest (odds ratio=2.29) and number of arrests (β=0.60), and this association was stronger for female patients than for male patients.

CONCLUSIONS

Findings suggest a need to address both past adversity and criminal justice system involvement in the context of early psychosis specialty care.

Childhood Adversity, Proximal Stressors and PTSD Among People with Severe Mental Illness: An Exploratory Study

The purpose of this exploratory study is to: (1) assess prevalence of childhood adversities and posttraumatic stress disorder (PTSD); (2) assess their association, and; (3) explore whether proximal sources of stress affect this relationship and/or have an association with PTSD among people with severe and persistent psychological disorders. Using data from 141 respondents, we assess the extent to which individuals in this population experienced 17 PTSD symptoms, various correlates to probable PTSD, and the most relevant of these factors in a multivariate logistic regression. Overall, 27% of the participants met study criteria for probable PTSD and each symptom was reported by at least 18% of the sample. Multivariate logistic regression models indicated that interpersonal conflict and being a victim of a crime were significantly related to probable PTSD. We discuss these findings in relation to treatment and course of disease for people suffering from severe and persistent mental illness experiencing a traumatic event.

The Manitoba Personalized Lifestyle Research (TMPLR) study protocol: a multicentre bidirectional observational cohort study with administrative health record linkage investigating the interactions between lifestyle and health in Manitoba, Canada

INTRODUCTION

Lifestyle factors, such as diet, physical activity and sleep, are associated with the development of many chronic diseases. The objective of The Manitoba Personalized Lifestyle Research study is to understand how these lifestyle factors interact with each other and with other factors, such as an individual's genetics and gut microbiome, to influence health.

METHODS

An observational study of adults, with extensive phenotyping by objective health and lifestyle assessments, and retrospective assessment of early life experiences, with retrospective and prospective utilisation of secondary data from administrative health records.

STUDY POPULATION

A planned non-random convenience sample of 840 Manitobans aged 30-46 recruited from the general population, stratified by sex (equal men and women), body mass index (BMI; 60% of participants with a BMI>25 kg/m²) and geography (25% from rural areas). These stratifications were selected based on Manitoba demographics.

MEASUREMENTS

Lifestyle factors assessed will include dietary pattern, physical activity, cardiovascular fitness, and sleep. Factors such as medical history, socioeconomic status, alcohol and tobacco consumption, cognition, stress, anxiety, and early life experiences will also be documented. A maternal survey will be performed. Body composition and bone density will be measured by dual energy X-ray absorptiometry. Blood pressure, pulse wave velocity, and augmentation index will be measured on two consecutive days. Chronic disease risk biomarkers will be measured in blood and urine samples. DNA will be extracted for genetic analysis. A faecal sample will be collected for microbiome analysis. Participants may provide their Manitoba personal health information number to link their study data with administrative health records.

ETHICS AND DISSEMINATION

Ethics approval has been obtained from the University of Manitoba Health Research Ethics Board (protocol # HS18951; 05/01/2016). Data analysis, release of results and publication of manuscripts are scheduled to start in early 2019. Additional information at www.TMPLR.ca.

Treatment-Resistant to Antipsychotics: A Resistance to Everything? Psychotherapy in Treatment-Resistant Schizophrenia and Nonaffective Psychosis: A 25-Year Systematic Review and Exploratory Meta-Analysis

Background: Roughly 30% of schizophrenia patients fail to respond to at least two antipsychotic trials. Psychosis has been traditionally considered to be poorly sensitive to psychotherapy. Nevertheless, there is increasing evidence that psychological interventions could be considered in treatment-resistant psychosis (TRP). Despite the relevance of the issue and the emerging neurobiological underpinnings, no systematic reviews have been published. Here, we show a systematic review of psychotherapy interventions in TRP patients of the last 25 years. Methods: The MEDLINE/PubMed, ISI WEB of Knowledge, and Scopus databases were inquired from January 1, 1993, to August 1, 2018, for reports documenting augmentation or substitution with psychotherapy for treatment-resistant schizophrenia (TRS) and TRP patients. Quantitative data fetched by Randomized Controlled Trials (RCTs) were pooled for explorative meta-analysis. Results: Forty-two articles have been found. Cognitive behavioral therapy (CBT) was the most frequently recommended psychotherapy intervention for TRS (studies, n = 32, 76.2%), showing efficacy for general psychopathology and positive symptoms as documented by most of the studies, but with uncertain efficacy on negative symptoms. Other interventions showed similar results. The usefulness of group therapy was supported by the obtained evidence. Few studies focused on negative symptoms. Promising results were also reported for resistant early psychosis. Limitations: Measurement and publication bias due to the intrinsic limitations of the appraised original studies. Conclusions: CBT, psychosocial intervention, supportive counseling, psychodynamic psychotherapy, and other psychological interventions can be recommended for clinical practice. More studies are needed, especially for non-CBT interventions and for all psychotherapies on negative symptoms.

Demographic and socioenvironmental predictors of premorbid marijuana use among patients with first-episode psychosis

OBJECTIVE

We identified, in subjects with first-episode psychosis, demographic and socioenvironmental predictors of three variables pertaining to premorbid marijuana use: age at initiation of marijuana use, trajectories of marijuana use in the five years prior to onset of psychosis, and the cumulative "dose" of marijuana intake in that same premorbid period.

METHODS

We enrolled 247 first-episode psychosis patients and collected data on lifetime marijuana/alcohol/tobacco use, age at onset of psychosis, diverse socioenvironmental variables, premorbid adjustment, past traumatic experiences, perceived neighborhood-level social disorder, and cannabis use experiences. Bivariate tests were used to examine associations between the three premorbid marijuana use variables and hypothesized predictors. Regression models determined which variables remained independently significantly associated.

RESULTS

Age at initiation of cigarette smoking was linked to earlier initiation, faster escalation, and higher cumulative dose of premorbid marijuana use. During childhood, poorer academic performance was predictive of an earlier age at initiation of marijuana use, while poorer sociability was related to more rapid escalation to daily use and a higher cumulative dose. As expected, experiencing euphoric effects was positively correlated with trajectories and cumulative dose, but having negative experiences was unrelated. Traumatic childhood/adolescent experiences were correlated with rapid escalation and amount of marijuana used, but not with age at initiation of marijuana use.

CONCLUSION

These data expand the very limited literature on predictors of premorbid marijuana use in first-episode psychosis. Given its association with earlier age at onset of psychosis, and poorer outcomes among first-episode patients, prevention and treatment efforts should be further developed.

Impact of stressful life events on central adiposity in the Pelotas Birth Cohort

OBJECTIVE:

To investigate how stressful life events and social support relate to central adiposity in Southern Brazil.

METHODS:

Data included information from 802 participants in the 1982 Pelotas Birth Cohort that was collect in 2004-2005 and 2006. Stratifying by sex, we studied self-reported stressful life events during the year before 2004-2005 in relation to change in waist circumference between 2004-2005 and 2006 and waist-to-hip ratio in 2006, using both bivariate and multivariate linear regression models.

RESULTS:

In adjusted models, the experience of stressful life events during the year before 2004-2005 predicted a change in waist circumference in 2006 in men and a change in both waist-to-hip ratio in 2006 and waist circumference between 2004-2005 and 2006 in women. Men who experienced two or more stressful events had on average a one centimeter increase in their waist circumference between 2004-2005 and 2006 (β = 0.97, 95%CI 0.02-1.92), compared to those reporting no stressful events. For women, those who had one and those who had two or more stressful life events had over a 1 cm increase in their waist circumference from 2004-2005 to 2006 (β = 1.37, 95%CI 0.17-2.54; β = 1.26, 95%CI 0.11-2.40, respectively), compared to those who did not experience any stressful event. For both sexes, social support level was not significantly related to either waist-to-hip ratio or change in waist circumference, and it did not modify the association between stress and central adiposity.

CONCLUSIONS:

The experience of more than one stressful life event was associated with distinct indicators of central adiposity for men versus women.

The Trauma and Life Events (TALE) checklist: development of a tool for improving routine screening in people with psychosis

Background: Best practice guidelines recommend traumatic events should be assessed in psychosis to support the identification and, when indicated, treatment of post-traumatic stress reactions. However, routine assessment in frontline services is rare, and available tools are not tailored to psychosis. Assessment obstacles include lengthy measures, a focus on single, physically threatening events, and the exclusion of psychosis-related traumas. Objective: To develop and validate a brief trauma screening tool for the identification of clinically significant traumas in people with psychosis. Method: The Trauma and Life Events (TALE) checklist was developed in conjunction with people with lived experience of trauma and psychosis, and specialist clinicians and researchers. The psychometric properties (i.e. test-retest reliability, content validity, construct validity) of the TALE were evaluated in a sample of 39 people with psychosis diagnoses. Results: The TALE displayed moderate psychometric acceptability overall, with excellent reliability and convergent validity for sexual abuse. High rates of psychosis-related trauma and childhood adversity were reported, in particular bullying and emotional neglect. A dose-response relationship between cumulative trauma, post-traumatic stress and psychosis was found. Conclusions: The TALE is the first screening tool specifically designed to meet the needs of routine trauma screening in psychosis services. The psychometric limitations highlight the challenge of developing a measure that is both sufficiently brief to be useful in clinical settings and comprehensive enough to identify all relevant adverse events. Validation of the TALE is now required across the spectrum of psychosis.

Development and validation of the Questionnaire of Stressful Life Events (QSLE)

Stressful life events (SLEs) are important indicators prior to the onset of first-episode psychosis (FEP). Although there are well-validated interviews and self-reports for assessing SLE on proximate events, unfortunately there are no instruments to assess SLE covering an entire lifetime. This study includes detailed specific items of childhood, adolescence, and adulthood focused on the presence of SLE, emotional impact (stressfulness), and the age at which the event occurred. Our research describes 2 studies designed to develop and validate a new scale to assess SLE: the Questionnaire of Stressful Life Events (QSLE). In Study 1, an over-inclusive item pool was generated based on review of group of experts at Parc Sanitari Sant Joan de Déu and content validity was examined by an Expert Survey. The whole scale represents the content domain. In Study 2, item-level analyses revealed good distributional properties, intra-rater reliability, and convergent and discriminant validity. In the sensitivity and specificity analysis, 18 items had high relevance in the discriminability between patients with FEP and healthy controls. We note that there was an AUC of 0.676, indicating a good predictor. Using 7 as a cutoff to predict an individual as a patient would yield a sensitivity of 64.8% and a specificity of 65%. Overall, the QSLE displayed satisfactory psychometric characteristics in a Spanish population. These results suggest that QSLE gives us the opportunity to investigate childhood, adolescent, and adult life events by measuring the stress and age at the moment on a continuous scale.

Auditory and non-auditory hallucinations in first-episode psychosis: Differential associations with diverse clinical features

Data from 247 first-episode psychosis patients were used to explore associations between types of hallucinations and nine diverse clinical characteristics. Psychopathology was rated using the Scale for the Assessment of Positive Symptoms and Scale for the Assessment of Negative Symptoms (SANS). Childhood adversity was assessed with seven instruments; family history with an adapted version of the Family Interview for Genetic Studies; age at onset of psychosis and duration of untreated psychosis (DUP) with the Symptom Onset in Schizophrenia inventory; and insight with the Birchwood Insight Scale. Both principal component analysis-derived Auditory and Non-Auditory Hallucinations were similarly associated with delusions of influence, negative affect delusions (jealousy and sin/guilt), interpersonal childhood abuse, DUP, and insight. However, the two hallucination domains had different associations with grandiose/religious, paranoid, and somatic delusions; SANS score; childhood violence exposure; cannabis use disorders; and cocaine/other drug use disorders. Neither Auditory nor Non-Auditory Hallucinations were associated with childhood neglect, age at onset, alcohol use disorders, family history, or mode of onset of psychosis. Findings support considering hallucinations not as a unitary psychopathological construct. They represent at least two domains and are correlated in different ways with diverse clinical variables.

Delusions in first-episode psychosis: Principal component analysis of twelve types of delusions and demographic and clinical correlates of resulting domains

Although delusions represent one of the core symptoms of psychotic disorders, it is remarkable that few studies have investigated distinct delusional themes. We analyzed data from a large sample of first-episode psychosis patients (n=245) to understand relations between delusion types and demographic and clinical correlates. First, we conducted a principal component analysis (PCA) of the 12 delusion items within the Scale for the Assessment of Positive Symptoms (SAPS). Then, using the domains derived via PCA, we tested a priori hypotheses and answered exploratory research questions related to delusional content. PCA revealed five distinct components: Delusions of Influence, Grandiose/Religious Delusions, Paranoid Delusions, Negative Affect Delusions (jealousy, and sin or guilt), and Somatic Delusions. The most prevalent type of delusion was Paranoid Delusions, and such delusions were more common at older ages at onset of psychosis. The level of Delusions of Influence was correlated with the severity of hallucinations and negative symptoms. We ascertained a general relationship between different childhood adversities and delusional themes, and a specific relationship between Somatic Delusions and childhood neglect. Moreover, we found higher scores on Delusions of Influence and Negative Affect Delusions among cannabis and stimulant users. Our results support considering delusions as varied experiences with varying prevalences and correlates.

Epidemiology of trauma: Childhood adversities, neighborhood problems, discrimination, chronic strains, life events, and daily hassles among people with a severe mental illness

Trauma during childhood and adolescence is a common event among people with a serious psychological disorder. Few studies assess a wide range of stressors for this population. This is surprising given that these stressful events are implicated in poorer outcomes related to course and treatment of mental health problems. This study of 214 people with serious mental illness examines the prevalence of childhood traumas, perceived neighborhood problems, discrimination, chronic strains, negative life events, and daily hassles. We use regression analyses to determine if these stressors are associated with quality of life. Results show that 95% of the sample report at least one childhood adversity. Perceived neighborhood problems, experiences of discrimination, chronic strains, life events, and daily hassles were also common. Examining the relationship between demographic factors and stressors suggests that older respondents, Whites, those who have never been married, and people diagnosed with Schizophrenia reported fewer stressors compared to those who are older, non-White, ever married, or suffering from other types of mental health problems. Finally, three of the six types of stressors were related to lower quality of life and depression. We discuss the implications of these findings for the treatment of severe psychological problems.
