Predictors of community functioning in schizophrenia and substance use disorder patients

Characterization and prediction of individual functional outcome trajectories in schizophrenia spectrum disorders (PREDICTS study): Study protocol

Schizophrenia spectrum disorders (SSDs) are associated with significant functional impairments, disability, and low rates of personal recovery, along with tremendous economic costs linked primarily to lost productivity and premature mortality. Efforts to delineate the contributors to disability in SSDs have highlighted prominent roles for a diverse range of symptoms, physical health conditions, substance use disorders, neurobiological changes, and social factors. These findings have provided valuable advances in knowledge and helped define broad patterns of illness and outcomes across SSDs. Unsurprisingly, there have also been conflicting findings for many of these determinants that reflect the heterogeneous population of individuals with SSDs and the challenges of conceptualizing and treating SSDs as a unitary categorical construct. Presently it is not possible to identify the functional course on an individual level that would enable a personalized approach to treatment to alter the individual's functional trajectory and mitigate the ensuing disability they would otherwise experience. To address this ongoing challenge, this study aims to conduct a longitudinal multimodal investigation of a large cohort of individuals with SSDs in order to establish discrete trajectories of personal recovery, disability, and community functioning, as well as the antecedents and predictors of these trajectories. This investigation will also provide the foundation for the co-design and testing of personalized interventions that alter these functional trajectories and improve outcomes for people with SSDs.

Interpersonal Risk Factors for Suicide in Cocaine Dependence: Association with Self-Esteem, Personality Traits, and Childhood Abuse

OBJECTIVE

Studies have linked cocaine dependence to suicidality. According to the Interpersonal Theory of Suicide, suicidal behavior becomes likely with the simultaneous presence of perceived burdensomeness (PB), lack of (or thwarted) belongingness (TB), and acquired fearlessness about death (FAD). Here, we examined personality and other variables, including depression, self-esteem, childhood abuse, and substance use, as predictors of these risk factors in cocaine-dependent individuals (CDs).

METHODS

Seventy CDs and 70 healthy controls (HCs) participated. We examined group differences in a group-by-sex analysis of variance and identified predictors of PB, TB, and FAD in stepwise regressions.

RESULTS

CDs exhibited elevated PB and TB but not FAD, compared to HCs. CDs also exhibited elevated harm avoidance, novelty seeking, depression, and lower self-esteem and reward dependence. Females reported elevated sexual abuse, harm avoidance, reward dependence, depression, but lower FAD, relative to males, among CDs and HCs. Among CDs, PB was predicted by lower self-esteem and greater emotional abuse; TB was predicted by lower self-esteem and reward dependence, as well as greater emotional and sexual abuse; and FAD was predicted by lower harm avoidance and greater physical abuse.

CONCLUSIONS

Interventions targeting suicidality in cocaine dependence should take into consideration self-esteem, personality traits, and childhood abuse.

Predictors of Mental Health Recovery in Homeless Adults with Mental Illness

For people with mental illness, experiences of homelessness can complicate mental health recovery processes. This study used longitudinal data from a randomized controlled trial of housing first (HF) to examine predictors of recovery among homeless people with mental illness. Findings showed that health and community predictors were most strongly associated with mental health recovery. Receipt of HF did not have any effect on changes in recovery scores at follow-up. Overall, the findings suggest that interventions aimed at preventing chronic homelessness, strengthening social networks and community involvement, and providing case management services will facilitate mental health recovery.

Factors Associated with Changes in Community Ability and Recovery After Psychiatric Rehabilitation: A Retrospective Study

One of the key goals of psychiatric rehabilitation is to return individuals with mental illnesses back into the community via restoration of the necessary skills. This retrospective study seeks to evaluate the factors associated with improvement in community functioning after a period of outpatient rehabilitation. 223 individuals enrolled into three broad rehabilitation groups-clinical, vocational and creative therapies/individual sessions-were included in this study. The Multnomah Community Ability Scale (MCAS) and Milestones of Recovery Scale (MORS) were used to evaluate each individual before and after the rehabilitation programme. Across all three groups, there were significant improvements in MCAS scores and MORS ratings. In multivariate models, clinical rehabilitation group was superior to creative therapies/individual sessions in predicting MORS change. The study also revealed a close relationship between recovery gains and improvement in community ability.

Living with schizophrenia in rural communities in north-east Thailand

In the rural villages of Thailand, rich social support networks exist that bond the community members to help each other. This study explored the barriers and facilitators of living with schizophrenia in Thai villages. A descriptive qualitative study was conducted using semi-structured interviews with individuals with schizophrenia, family members, and significant others. Content analysis of transcripts involved examining the data, recording observations, data reduction, and coding themes. Four main themes emerged from the narratives: (i) keep doing day-to-day activities as a way of life; (ii) support sustains day-to-day living; (iii) controlling medication side effects maintains daily living; and (iv) managing self maintains daily living. Self-regulation and social support are keys to moving from dependence to a normative life goal in rural communities. The patterns of living in the rural communities provide a strong social network as people with schizophrenia learn to lead successful lives. Using supportive families and community members as resources is an alternative and effective way of providing supportive care.

Depressed mood in individuals with schizophrenia: A comparison of retrospective and real-time measures

Depressed mood is prevalent among individuals with schizophrenia, leading to difficulties in functioning. Typically, depressed mood is evaluated using retrospective assessments during which individuals are asked to recall their mood during the past week or month. However, as individuals with schizophrenia may display memory difficulties, the results of such assessments may be biased, potentially leading to inaccurate clinical characterizations and/or suboptimal treatment. Our aim was to assess the potential impact of long-term memory on depressed mood in individuals with schizophrenia. Employing an Experience Sampling Method (ESM) approach, 51 individuals with schizophrenia and 22 healthy controls rated their momentary emotions up to 10 times/day over a two-day period, along with retrospective measures of depressed mood, long-term memory, quality of life, social functioning, and symptoms. ESM assessment of real-time depressed mood demonstrated discriminant and convergent validity. Among the schizophrenia group, there was a significant correlation between the real-time and retrospective measures of depressed mood. However, once variance due to long-term memory was controlled, the relationship between the real-time and retrospective measure was no longer significant. The findings suggest that a real-time measure of depressed mood may allow overcoming some of the limitations associated with long-term memory difficulties common among individuals with schizophrenia.
