The iCBT programme comprised of 6 online modules, delivered over 4 weeks, with 3 face-to-face sessions provided by a clinician.The face-to-face sessions were conducted at week 1, 3 and 4. The objectives of the face-to-face sessions was for participants to discuss with the clinician about the application of the content of the modules and the active therapeutic interventions were all found in the online modules.

The delayed wait-list control did not receive any therapy interventions for 4 weeks from the pre-treatment assessment and from the fifth week onwards, they received the same intervention as the iCBT experimental group.

The iCBT programme comprised on 6 online modules. Module 1 provided an introduction to the symptoms of depression, its causes and information on CBT. Module 2 covered problem-solving strategies. Module 3 provided information on problematic thought patterns and beliefs in depression. Module 4 entailed identifying problematic thought patterns and using various techniques to counter problematic thoughts. Module 5 covered pleasurable activities scheduling to help increase activity levels.

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).

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).
