    Improving adherence in mental health service users with severe mental illness in South Africa: a pilot randomized controlled trial of a treatment partner and text message intervention vs. treatment as usual
    (BioMed Central, 2017-11-09) Sibeko, Goodman; Sibeko, Goodman; Mall, Sumaya; Williams-Ashman, Peter; Thornicroft, Graham; Susser, Ezra S; Lund, Crick; Stein, Dan J; Milligan, Peter D
    Objectives: Medication non-adherence is a significant problem in treatment of severe mental disorders and is associated with poor clinical outcomes and increased demand on services. Task-shifting interventions incorporating mobile health may improve adherence in mental health service users in low- and middle-income countries. Seventy-seven participants were recruited from a psychiatric hospital in Cape Town, with 42 randomized to receive the intervention and 35 to treatment as usual. Intervention pairs underwent treatment-partner contracting and psychoeducation, and received monthly text message reminders of clinic appointments. Primary outcomes were intervention acceptability and feasibility. Secondary outcome for efficacy were adherence to clinic visit; relapse; quality of life; symptomatic relief and medication adherence. Results: Treatment partner and psychoeducation components were acceptable and feasible. The text message component was acceptable but not feasible in its current form. Efficacy outcomes favoured the intervention but did not reach statistical significance. A treatment-partner intervention is acceptable and feasible in a low- and middle-income setting. Work is needed to ensure that additional components of such interventions are tailored to the local context. Appropriately powered efficacy studies are needed.

    Piloting a mental health training programme for community health workers in South Africa: an exploration of changes in knowledge, confidence and attitudes
    (BioMed Central, 2018-06-14) Sibeko, Goodman; Milligan, Peter D; Roelofse, Marinda; Molefe, Lezel; Jonker, Deborah; Ipser, Jonathan; Lund, Crick; Stein, Dan J
    Background There is a shortage of trained mental health workers in spite of the significant contribution of psychiatric disorders to the global disease burden. Task shifting, through the delegation of health care tasks to less specialised health workers such as community health workers (CHWs), is a promising approach to address the human resource shortage. CHWs in the Western Cape province of South Africa provide comprehensive chronic support which includes that for mental illness, but have thus far not received standardized mental health training. It is unknown whether a structured mental health training programme would be acceptable and feasible, and result improved knowledge, confidence and attitudes amongst CHWs. Methods We developed and piloted a mental health training programme for CHWs, in line with the UNESCO guidelines; the WHO Mental Health Gap Action Programme and the South African National framework for CHW training. In our quasi-experimental (before-after) cohort intervention study we measured outcomes at the start and end of training included: 1) Mental health knowledge, measured through the use of case vignettes and the Mental Health Knowledge Schedule; 2) confidence, measured with the Mental Health Nurse Clinical Confidence Scale; and 3) attitudes, measured with the Community Attitudes towards the Mentally Ill Scale. Knowledge measures were repeated 3 months later. Acceptability data were obtained from daily evaluation questionnaires and a training evaluation questionnaire, while feasibility was measured by participant attendance at training sessions. Results Fifty-eight CHWs received the training, with most (n = 56, 97.0%) attending at least 7 of the 8 sessions. Most participants (n = 29, 63.04%) demonstrated significant improvement in knowledge, which was sustained at 3-months. There was significant improvement in confidence, along with changes in attitude, indicating improved benevolence, reduced social restrictiveness, and increased tolerance to rehabilitation of the mentally ill in the community but there was no change in authoritarian attitudes. The training was acceptable and feasible. Conclusions Mental health training was successful in improving knowledge, confidence and attitudes amongst trained CHWs. The training was acceptable and feasible. Further controlled studies are required to evaluate the impact of such training on patient health outcomes.

    Prevalence and correlates of anxiety disorders in psychotic illness
    (2017) Reid, Kirsten; Milligan, Peter D; Temmingh, Henk
    Background: Comorbid anxiety disorders in psychotic illness are reported in the international literature as highly prevalent and have a significant negative impact on patient outcomes. Local literature describing such comorbidity in the South African population is limited and clinically, anxiety symptoms are seldom recognised or treated in patients with psychotic disorders. More data on prevalence rates across psychotic disorder diagnoses, as well as sociodemographic correlates would aid recognition, diagnosis, and treatment, and potentially improve clinical outcomes in this population. Method: We performed a secondary analysis of an existing database which comprised data from participants of three previous studies. The sample was made up of patients from Valkenberg Hospital and healthcare facilities in its catchment area. All patients had a diagnosis of a psychotic disorder. Socio-demographic information was collected using a structured questionnaire. Clinical information and diagnosis was determined using the Structured Clinical Interview for DSM (SCID-I). Rates of comorbid anxiety disorders were compared across various sociodemographic categories. Results: The overall prevalence of any anxiety disorder in the entire sample (N=226) was 14.6% (n=33), 95% CI [10.27-19.89%]. The most common anxiety disorder comorbidities were, in descending order, panic disorder (n=12, 5.31%; 95% CI [2.77-9.09%]), PTSD (n=9, 3.98%; 95% CI [1.84-7.42%]), specific phobia (n=7, 3.10%; 95% CI [1.25-6.28%]), anxiety disorder not otherwise specified (n=7, 3.10%; 95% CI [1.25-6.28%]), social phobia (n=4, 1.77%; 95% CI [0.48%-4.47%]), generalised anxiety disorder (n=4, 1.77%; 95% CI [0.48-4.47%]), substance-induced anxiety disorder (n=4, 1.77%; 95% CI [0.48-4.47%]) and obsessive compulsive disorder (n=2, 0.88%; 95% CI [0.11-3.16%]). There was a significant association between diagnosis and the presence of post-traumatic stress disorder (PTSD), with the schizoaffective disorder group having a higher rate of PTSD (13.3% vs. 3.3% in schizophrenia, 3.2% in substance-induced mood/psychotic disorder and 0% in bipolar I disorder) (Fisher's exact test, p=0.039). In turn, there was a trend level association between diagnosis and the presence of panic disorder (PD), with schizoaffective disorder patients having higher rates of PD (16.6% vs. 4.1% in schizophrenia spectrum, 3.2% in substance-induced mood/psychotic disorder and 2.2% in bipolar I disorder) (Fisher's exact test, p=0.052). A significant association was found between level of education and the presence of PTSD, with higher rates of PTSD in patients with seven or less years of education (8.8%) compared to lower rates in those with 8-12 years of education (5.3%) and > 12years of education (0%) (Fisher's exact test, p=0.020). Conclusion: The overall prevalence of anxiety disorders in psychotic illness was lower than what has been described in previous literature. Prevalence rates of individual anxiety disorders were also lower than previously published literature. Possible reasons for this include use of the SCID which utilises a strict diagnostic hierarchy, that the majority of the sample were in-patients, no use of self-report questionnaires or other anxiety-specific diagnostic instruments, or possible geographical and/or ethnic differences in South African patients. The most frequent comorbid anxiety disorders in our study were panic disorder and PTSD. This is out of keeping with other literature which has mostly found obsessive compulsive disorder and social anxiety disorder to be the most common anxiety comorbidities in psychotic illness. Further research into comorbid anxiety in psychotic disorders is needed, particularly amongst South African populations.
