Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Patient Health Questionnaire-9 (PHQ9)	The PHQ-9 is a nine-item self-report measure of symptoms and severity of major depressive disorder, based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV; American Psychiatric Association, 2000) criteria for Major Depressive Disorder. Scores on each item range from 0 (not at all) to 3 (nearly every day). An overall cut-off score of 10 or greater has been found to be sensitive to a DSM-IV diagnosis of depression (Kroenke, Spitzer, Williams, amp; Löwe, 2010). The PHQ9 has an internal reliability of 0.86- 0.89, sensitivity of 88% and specificity of 88% for the clinical cut-off of 10. Test-retest reliability of 0.84, and moderately correlated(r=0.58) with the SF-20 mental health scale. (Kronke et al.,2001).	week 1, week 3, week 4 and 3-month follow-up
Secondary	Change in Generalised Anxiety Disorder-7 (GAD-7)	The GAD-7 is a seven-item self-report measure of symptoms and severity of Generalised Anxiety Disorder (GAD), based on the DSM-IV criteria for GAD. Scores for each item range from 0 (not at all) to 3 (nearly every day). An overall cut-off score of 10 or greater has been found to be sensitive to DSM-IV diagnoses of GAD, social phobia and panic disorders (Kroenke, Spitzer, Williams, Monahan, amp; Lo ¨we, 2007). The GAD-7 has an internal reliability of 0.92, test-retest reliability of 0.83, and criterion validity of 0.75 with SF-20 mental health scale (Spitzer et al., 2006) .The GAD-7 is increasingly adopted in empirical studies and in large scale dissemination studies as a general measure of shifts in anxiety symptoms (Clark et al., 2009).	week 1, week 3, week 4 and 3-month follow-up
Secondary	Change in Work and Social Adjustment Scale (WSAS)	The WSAS is a five-item self-report measure of the extent of impairment in work and social functioning. Scores ranged from 0 to 40. An overall score of above 20 appears to suggest moderately severe or worse psychopathology. Scores between 10 and 20 are associated with significant functional impairment but less severe clinical symptomatology. The WSAS has an internal reliability of 0.70-0.94, Test-retest reliability of 0.73. Convergent validity compared with clinical interviews and severity of depression is 0.76-0.86.	week 1, week 3, week 4 and 3-month follow-up
