Common mental disorders are very prevalent and significantly impact the lives of many people in low-and middle-income countries, including South Africa. A nationally representative study revealed that 30% of South African adults had a DSM-IV disorder in their lifetime, including 16% with an anxiety disorder and 10% with a mood disorder [
1]. Depression and anxiety disorders can be chronic [
2], severely impair quality of life [
3], cause excess mortality [
4], and incur substantial societal costs [
5]. In South Africa, psychiatric disorders were ranked as the third most disabling condition, after HIV/AIDS and other infectious diseases [
6], while many HIV/AIDS sufferers had comorbid mental disorders [
7].
Despite this high prevalence of common mental disorders, many who suffer from these conditions do not receive treatment. In a recent survey, only a quarter of South Africans with a 12-month DSM-IV diagnosis of anxiety or depression had been treated in the preceding year [
8,
9]. This is unsurprising as there are many barriers to treatment, including the fact that resources are inadequate and unevenly distributed across the country [
9-
13]. Most services are located in the urban areas and are still characterized by patterns created by racial segregation and inequities during the apartheid system [
14,
15]. The integration of mental health care into primary care facilities has been said to lack behind due to primary care nurses' large workloads and lack in mental health training [
16].
The number of people with mental health problems receiving no treatment is 30-50% in high income countries and 76-80% in low-and middle income countries (LAMICs) [
17]. The World Health Organization (WHO) notes that this treatment gap is mainly due to a scarcity of human, mental health and financial resources which are also caused by policies in LAMIC. Many people who seek help are not treated with evidence-based interventions [
18]. Socio-economic status determines access to facilities, creating a huge inequity in access to mental health care in most low and middle-income countries [
19]. The WHO has called for increased investment in mental health research, particularly in LAMIC [
20] and the scaling up of services [
21]. Research can reinforce the commitment of policymakers and provide a concrete evidence-based programme to upscale care for mental disorders and to reduce the treatment gap for mental disorders in LAMIC.
Researchers are currently investigating the development of easily accessible, evidence-based, and cost-effective treatments. Self-help problem solving therapy (PST) could be one such approach. Guided-self help has had promising efficacy in anxiety disorders [
22-
24], unipolar depression [
24-
27], alcohol addiction [
28], sexual dysfunction [
29], weight loss [
29], and phobias [
30]. PST self-help can be guided face to face or by book, phone, interactive voice response, CD-ROM, television, video or the Internet. PST is a cognitive behavioural therapy (CBT) technique which is applicable in primary care [
31] and cost-effective in treating common mental health problems [
32-
37]. It assumes that depression and anxiety symptoms are often caused by practical everyday problems and aims to teach people better ways to cope with such problems by setting goals and minimizing feelings of incompetence and distress [
38]. PST can be sensitive to local needs, is efficacious for depression [
32-
37] and anxiety and emotional disorders [
39,
40], is well-established in developed world settings and requires fairly limited resources.
PST is thus a good candidate to narrow the treatment gap for mental disorders in South Africa. However, data on psychotherapies from high-income countries may not be generalisable to LAMICs [
41]. First, cultural factors can influence the conceptualization of common mental disorders by both patient and care providers. The attitudes of people in developed and developing countries often differ regarding the kind of help needed to resolve a disorder. Explanatory models in many low and middle-income countries may be less likely to acknowledge psychobiological factors in psychological distress. This may affect attitudes regarding the kind of help needed and the acceptability of mental health interventions. Second, the infrastructure of health systems across countries can diverge extensively. The applicability of treatment research from developed to LAMIC countries can be influenced by the scarcity of mental health manpower, the growth of the private medical sector, rising health costs, and changing health care financing systems [
41].
This pilot study aimed to adapt and test the feasibility and acceptability of low-cost PST in South African communities which have little or no access to mental health services. Our original implementation used a web-guided format of PST in different deprived communities around Cape Town. We found that the lack of access to a computer and the Internet and the lack of basic computer and Internet literacy among community members probably played a role in the poor take-up of our web-guided program, making it difficult to implement a web-guided intervention. When the recruitment of online PST users proved difficult we adapted the PST to a booklet format to see if this was more feasible and acceptable. Why online PST wasn't feasible and acceptable in South African communities is discussed in more detail in a previous paper [
42]. After deliberation with local community workers, we converted the online PST content to a booklet-plus-workshop PST version and evaluated its use. This paper presents the pilot results using the booklet and workshop version in deprived Cape Town communities.
