About
As CBT was developed for persons from North America and European background it needs to be adapted for persons from non-Western cultures. This mixed methods study proposes a culturally adapted Cognitive Behavioural Therapy (CA-CBT) model for Canadians of South Asian origin. Beginning with a participatory/qualitative research approach, common themes amongst individuals with depression and/or anxiety, caregivers, healthcare professionals, and community leaders, will divulge basic elements needed to develop a culturally adapted model of cognitive behavioural therapy. The information from the adapted model will be taught to participating therapists who will deliver the therapy in a randomized control trial design, with feasibility testing of the intervention using a quantitative approach. Immediate guidelines will then be developed for use by therapists working with South Asian clients.

Background and Significance:
Canadians of South Asian (SA) origin, defined as individuals with ancestral ties to India, Pakistan, Bangladesh, Sri Lanka, Bhutan, Afghanistan, Maldives and Nepal, comprise the largest racialized group in Canada, amounting to 1.6 million individuals or 5% of the Canadian population and 32% of the Canadian Asian population. This makes them the largest visible minority group in Canada, comprising 25.6% of the visible minority population, followed by East Asian and African-Caribbean Canadians, respectively. The SA Canadians are disproportionately affected by high rates of anxiety and mood disorders, placing those immigrating to Canada at age 17 or younger at a significantly higher risk for this condition compared to immigrants from elsewhere who immigrated at the same age.
The SA Canadians are disproportionately impacted by the social determinants of health, including unemployment, low income, language barriers, low education, low literacy and migration stress. These factors can negatively impact mental health and decrease access to care, thereby increasing mental health inequities. Compared to other ethnocultural groups, SA Canadians with a major depressive episode reported the highest proportion of unmet mental health care needs (48%) and the highest percentage of perceived barriers to the availability of mental health care(33%). Canadians who had a major depressive episode and identified as SA were 85% less likely to seek treatment than Canadians who had experienced the same illness but identified as white. The lower use of mental health services by SA Canadians highlights the inequities in access to appropriate care for these populations.
The Mental Health Commission of Canada (MHCC) recommends improving Canadian mental health care to serve diverse populations with equitable, timely access to appropriate, effective, and evidence-based treatments that attend to unique sociocultural needs (Mental Health Commission of Canada, 2014). The MHCC Case for Diversity report further highlights the necessity for culturally and linguistically relevant services particularly for immigrant, refugee, ethnocultural and racialized populations, such as SA Canadians. In light of the new $5B targeted federal transfer to "improve access to mental health and addiction services and to structured psychotherapy" (Government of Canada, 2016) there is an opportunity to complement efforts to expand the access that adequately address the mental health needs of diverse Canadian populations.
Cognitive Behavioural Therapy in its current form is not suitable for persons from the non-western cultural background. Culturally-adapted Cognitive Behavioural Therapy (Ca_CBT) is an evidence-based practice. CaCBT is more effective than standard CBT and can reduce dropouts from therapy compared with standard CBT. Thus CaCBT can increase access to mental health services and improve outcomes for immigrant, refugee, ethnocultural and racialized populations. Adapting CBT for growing SA populations in Canada will ensure equitable access to effective, culturally-appropriate interventions. Accordingly, this study proposes to develop and evaluate Ca_CBT for depression and anxiety among SA populations in Canada.
Study Objectives:
The primary objective of the study is to develop culturally adapted CBT for South Asian persons with depression and anxiety. Secondary objectives include; (a) testing CaCBT against standard CBT for efficacy and cost-effectiveness, and (b) to test whether training in culturally adapted CBT can improve therapist's cultural competence.
Methods:
This mixed methods study will be conducted in three phases:
Phase 1: Cultural Adaptation of CBT Cultural adaptation of CBT for SA populations in Canada experiencing depression and anxiety using stakeholder consultations and qualitative methodology
Phase 2: Pilot Feasibility Testing of Ca_CBT Pilot test the newly developed Ca_CBT for feasibility, acceptability and effectiveness via quantitative methodology and a randomized controlled trial
Phase 3: Implementation & Evaluation of Ca_CBT Trained therapists working with SA populations to use Ca_CBT with their clients. Evaluate therapist competence in using Ca_CBT as well as client satisfaction with the newly developed therapy.
