Functioning and quality of life among treatment-engaged adults with psychotic disorders in urban Tanzania: Baseline results from the KUPAA clinical trial.

BACKGROUND: There is a treatment gap for those living with severe mental illnesses in low- and middle-income countries, yet not enough is known about those who are currently accessing clinical services. A better understanding of potentially modifiable factors associated with functioning and quality of life will help inform policies and programming. AIMS: To describe the functioning and quality of life for a psychiatric treatment-engaged population living with psychotic disorders in two urban areas of Tanzania, and to explore their respective correlates. METHODS: This study analyzed cross-sectional data from 66 individuals enrolled in the Kuwezeshana Kupata Uzima (KUPAA) pilot clinical trial who had a diagnosis of schizophrenia or schizoaffective disorder, recent relapse, and who were receiving outpatient treatment. Baseline functioning (WHO Disability Assessment Schedule 2.0) and quality of life (WHO Quality of Life BREF scale) were measured. Univariable and multivariable regression analyses were conducted to determine correlates of functioning and quality of life. RESULTS: Adjusted analyses indicated that higher disability was associated with higher food insecurity, more symptomatology, more self-stigma, less instrumental support, less hope, lower self-efficacy, and/or lower levels of family functioning. Higher quality of life was associated with higher levels of self-efficacy, more hopefulness, more instrumental support, less self-stigma, and better family functioning. CONCLUSIONS: Identification of factors associated with disability and quality of life can help clinicians and policymakers, as well as consumers of mental health services, to better co-design and target psychosocial interventions to optimize their impact in low-resource settings.

Perceived burden and family functioning among informal caregivers of individuals living with schizophrenia in Tanzania: a cross-sectional study.

BACKGROUND: Globally, families play a critical role in providing care and support for persons living with schizophrenia. It is important to identify potentially modifiable factors that influence perceived caregiver burden in order to properly address the needs of caregivers. This is especially relevant in low-resource settings where psychiatric services are scarce and interventions could be most effective if targeted to both the individual living with schizophrenia and their caregiver. This study examines correlates of perceived burden among informal caregivers of individuals with schizophrenia in Tanzania, in particular, the association between burden and caregiver-reported family functioning. METHODS: This study used baseline data from an individually randomized controlled trial with 65 pairs of individuals with schizophrenia and their informal caregivers in Dar es Salaam and Mbeya, Tanzania. Caregiver burden was measured using the Burden Assessment Scale. Univariable and multivariable regression analyses were performed to determine the relationship between caregiver burden and family functioning and to explore other correlates of burden. RESULTS: Sixty-three percent of caregivers reported experiencing high burden as a result of caring for a relative with schizophrenia. Multivariable regression analyses revealed that poor family functioning and the caregiver being employed were associated with high caregiver burden, while higher levels of hopefulness in the caregiver was associated with low caregiver burden. CONCLUSION: Caregivers who were employed, reported poor family functioning, and/or had low levels of hopefulness were more likely to perceive high caregiver burden. Future interventions aiming to reduce caregiver burden may benefit from improving family functioning and nurturing hope among caregivers of individuals living with schizophrenia. Policies and programs should be cognizant of the needs of caregivers that work in addition to providing care for a relative with schizophrenia in order to better support them.

A preliminary investigation of impulsivity, aggression and white matter in patients with bipolar disorder and a suicide attempt history.

BACKGROUND: Impulsivity and aggression may be associated with suicide attempts in bipolar disorder (BD), but findings have been inconsistent. Abnormalities in anterior white matter tracts that project to the frontal lobes mediate top-down regulation of emotion and may contribute to this clinical phenomenology. METHODS: We assessed white matter (i.e., fractional anisotropy) in anterior and posterior brain regions using diffusion tensor imaging in 18 patients with BD and no prior suicide attempt (BD-S), 12 patients with BD and a prior suicide attempt (BD+S), and 12 healthy volunteers. Patients completed the Urgency, Premeditation, Perseverance, Sensation Seeking, Positive Urgency (UPPS-P) Impulsive Behavior Scale and Impulsive Premeditated Aggression Scale (IPAS). All individuals completed the Barratt Impulsiveness Scale (BIS-11). RESULTS: Patients with BD+S had higher overall impulsivity (assessed using both the UPPS-P Impulsive Behavior Scale and BIS-11) and premeditated aggression compared to patients with BD-S. There were no significant group differences on measures of fractional anisotropy (FA). In patients with BD+S, however, higher FA in the anterior (but not the posterior) brain regions correlated with greater overall impulsivity on the UPPS-P Impulsive Behavior Scale. There were no significant correlations between either anterior or posterior brain regions with clinical measures in patients with BD-S. LIMITATIONS: Cross-sectional study, sample size and possible contribution of psychotropic medications. CONCLUSION: Impulsivity and aggression may be risk factors for a suicide attempt in BD. White matter in the anterior limb of the internal capsule and anterior corona radiata may play a role in this phenomenology.

Effects of childhood trauma on adult moral decision-making: Clinical correlates and insights from bipolar disorder.

BACKGROUND: Childhood adversity has been shown to exert profound effects on basic psychological processes well into adulthood. Some of these processes, such as those related to reward and emotion, play critical roles in moral decision-making. As a population with high rates of childhood trauma as well as heterogenous clinical presentation, individuals with bipolar disorder (BD) constitute an enriched group in which to examine the correlates of trauma and other clinical variables with moral cognition. METHODS: 62 euthymic BD patients and 27 controls responded to moral dilemma scenarios and completed the Childhood Trauma Questionnaire. RESULTS: Results revealed a main effect of diagnosis on moral decision-making only when both personal force and an intention were required, indicating a more utilitarian style in BD patients relative to controls. Several interesting patterns also emerged regardless of diagnostic status. Higher ratings of physical neglect were significantly associated with higher ratings of acceptability (a utilitarian tendency) across dilemma types, and a similar pattern was observed at the trend level for experiences of emotional neglect. Significant main effects on moral decision-making were also observed for sex, illness duration, and history of psychotic features in the BD sample. LIMITATIONS: The present study is limited by the self-reported nature of the CTQ and by the small number of trials of moral dilemmas. In addition, practical and clinical implications of the moral dilemmas paradigm are limited due to its abstract nature. CONCLUSIONS: Our results indicate that certain clinical features as well as childhood maltreatment (in particular neglect) may significantly impact moral decision making in adult life. Surprisingly, childhood trauma was associated with a more utilitarian style, which is in the opposite direction from previous effects shown in PTSD. Although speculative, our results suggest that there may be a protective quality associated with utilitarian moral decision-making tendencies.
