    Background Cell line immortalisation is a growing component of African genomics research and biobanking. However, little is known about the factors influencing consent to cell line creation and immortalisation in African research settings. We contribute to addressing this gap by exploring three questions in a sample of Xhosa participants recruited for a South African psychiatric genomics study: First, what proportion of participants consented to cell line storage? Second, what were predictors of this consent? Third, what questions were raised by participants during this consent process? Methods 760 Xhose people with schizophrenia and 760 controls were matched to sex, age, level of education and recruitment region. We used descriptive statistics to determine the proportion of participants who consented to cell line creation and immortalization. Logistic regression methods were used to examine the predictors of consent. Reflections from study recruiters were elicited and discussed to identify key questions raised by participants about consent. Results Approximately 40% of participants consented to cell line storage. The recruiter who sought consent was a strong predictor of participant’s consent. Participants recruited from the South African Eastern Cape (as opposed to the Western Cape), and older participants (aged between 40 and 59 years), were more likely to consent; both these groups were more likely to hold traditional Xhosa values. Neither illness (schizophrenia vs control) nor education (primary vs secondary school) were significant predictors of consent. Key questions raised by participants included two broad themes: clarification of what cell immortalisation means, and issues around individual and community benefit. Conclusions These findings provide guidance on the proportion of participants likely to consent to cell line immortalisation in genomics research in Africa, and reinforce the important and influential role that study recruiters play during seeking of this consent. Our results reinforce the cultural and contextual factors underpinning consent choices, particularly around sharing and reciprocity. Finally, these results provide support for the growing literature challenging the stigmatizing perception that people with severe mental illness are overly vulnerable as a target group for heath research and specifically genomics studies.

    Task sharing for the care of severe mental disorders in a low-income country (TaSCS): study protocol for a randomised, controlled, non-inferiority trial
    (BioMed Central, 2016-02-11) Hanlon, Charlotte; Alem, Atalay; Medhin, Girmay; Shibre, Teshome; Ejigu, Dawit A; Negussie, Hanna; Dewey, Michael; Wissow, Lawrence; Prince, Martin; Susser, Ezra; Lund, Crick; Fekadu, Abebaw
    Background: Task sharing mental health care through integration into primary health care (PHC) is advocated as a means of narrowing the treatment gap for mental disorders in low-income countries. However, the effectiveness, acceptability, feasibility and sustainability of this service model for people with a severe mental disorder (SMD) have not been evaluated in a low-income country. Methods/Design: A randomised, controlled, non-inferiority trial will be carried out in a predominantly rural area of Ethiopia. A sample of 324 people with SMD (diagnoses of schizophrenia, schizoaffective disorder, bipolar disorder or major depressive disorder) with an ongoing need for mental health care will be recruited from 1) participants in a population-based cohort study and 2) people attending a psychiatric nurse-led out-patient clinic. The intervention is a task-sharing model of locally delivered mental health care for people with SMD integrated into PHC delivered over 18 months. Participants in the active control arm will receive the established and effective model of specialist mental health care delivered by psychiatric nurses at an out-patient clinic within a centrally located general hospital. The hypothesis is that people with SMD who receive mental health care integrated into PHC will have a non-inferior clinical outcome, defined as a mean symptom score on the Brief Psychiatric Rating Scale, expanded version, of no more than six points higher, compared to participants who receive the psychiatric nurse-led service, after 12 months. The primary outcome is change in symptom severity. Secondary outcomes are functional status, relapse, service use costs, service satisfaction, drop-out and medication adherence, nutritional status, physical health care, quality of care, medication side effects, stigma, adverse events and cost-effectiveness. Sustainability and costeffectiveness will be further evaluated at 18 months. Randomisation will be stratified by health centre catchment area using random permuted blocks. The outcome assessors and investigators will be masked to allocation status. Discussion: Evidence about the effectiveness of task sharing mental health care for people with SMD in a rural, low-income African country will inform the World Health Organisation’s mental health Gap Action Programme to scale-up mental health care globally.

    Task sharing of a psychological intervention for maternal depression in Khayelitsha, South Africa: study protocol for a randomized controlled trial
    (BioMed Central, 2014-11-21) Lund, Crick; Schneider, Marguerite; Davies, Thandi; Nyatsanza, Memory; Honikman, Simone; Bhana, Arvin; Bass, Judith; Bolton, Paul; Dewey, Michael; Joska, John; Kagee, Ashraf; Myer, Landon; Petersen, Inge; Prince, Martin; Stein, Dan J; Thornicroft, Graham; Tomlinson, Mark; Alem, Atalay; Susser, Ezra
    Background: Maternal depression carries a major public health burden for mothers and their infants, yet there is a substantial treatment gap for this condition in low-resourced regions such as sub-Saharan Africa. To address this treatment gap, the strategy of “task sharing” has been proposed, involving the delivery of interventions by non-specialist health workers trained and supervised by specialists in routine healthcare delivery systems. Several psychological interventions have shown benefit in treating maternal depression, but few have been rigorously evaluated using a task sharing approach. The proposed trial will be the first randomised controlled trial (RCT) evaluating a task sharing model of delivering care for women with maternal depression in sub-Saharan Africa. The objective of this RCT is to determine the effectiveness and cost-effectiveness of a task sharing counseling intervention for maternal depression in South Africa. Methods/Design: The study is an individual-level two-arm RCT. A total of 420 depressed pregnant women will be recruited from two ante-natal clinics in a low-income township area of Cape Town, using the Edinburgh Postnatal Depression Scale to screen for depression; 210 women will be randomly allocated to each of the intervention and control arms. The intervention group will be given six sessions of basic counseling over a period of 3 to 4 months, provided by trained community health workers (CHW)s. The control group will receive three monthly phone calls from a CHW trained to conduct phone calls but not basic counseling. The primary outcome measure is the 17-Item Hamilton Depression Rating Scale (HDRS-17). The outcome measures will be applied at the baseline assessment, and at three follow-up points: 1 month before delivery, and 3 and 12 months after delivery. The primary analysis will be by intention-to-treat and secondary analyses will be on a per protocol population. The primary outcome measure will be analyzed using linear regression adjusting for baseline symptom severity measured using the HDRS-17. Discussion: The findings of this trial can provide policy makers with evidence regarding the effectiveness and cost-effectiveness of structured psychological interventions for maternal depression delivered by appropriately trained and supervised non-specialist CHWs in sub-Saharan Africa.

    The content of delusions in a sample of South African Xhosa people with schizophrenia
    (BioMed Central, 2017-01-24) Campbell, Megan M; Sibeko, Goodman; Mall, Sumaya; Baldinger, Adam; Nagdee, Mohamed; Susser, Ezra; Stein, Dan J
    Background: Although the relationship between cultural beliefs and schizophrenia has received some attention, relatively little work has emerged from African contexts. In this study we draw from a sample of South African Xhosa people with schizophrenia, exploring their cultural beliefs and explanations of illness. The purpose of the article is to examine the relationship between this cultural context and the content of delusions. Methods: A sample comprising 200 Xhosa people with schizophrenia participating in a South African schizophrenia genomics study were interviewed using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). Participant delusions were thematically analyzed for recurring themes. Results: The majority of participants (n = 125 72.5%) believed that others had bewitched them in order to bring about their mental illness, because they were in some way jealous of the participant. This explanation aligns well with the understanding of jealousy-induced witchcraft in Southern African communities and highlights the important role that culture plays in their content of delusions. Conclusions: Improved knowledge of these explanatory frameworks highlights the potential value of culturally sensitive assessment tools and stigma interventions in patient recovery. Furthermore such qualitative analyses contribute towards discussion about aspects of delusional thought that may be more universally stable, and those that may be more culturally variable.
