Among the various psychotherapy treatments available, Cognitive Behavioural Therapy (CBT) is recommended as a first-line treatment for depression, and behavioural activation alone is recommended as a second-line therapy (National Institute for Health and Clinical Excellence [NICE], 2018). CBT is an integrative treatment that incorporates many therapeutic techniques, including the core techniques of cognitive restructuring and behaviour activation (Beck & Beck, 2011; Friedberg & Brelsford, 2011; O’Donohue & Fisher, 2012). Research appears to demonstrate conflicting results regarding the importance of both types of interventions in the treatment of depression (Cuijpers et al., 2007; Ekers et al., 2008; Mazzucchelli et al., 2009). Given this, and given the extensive literature base on CBT and more specifically on cognitive interventions and behavior activation interventions, a next step would be to review the available literature. This manuscript-based thesis includes three studies related to therapist technique within CBT. The overarching purpose of this research endeavor is to better understand therapist technique in CBT through exploring and summarizing information on therapist techniques and through examining how these techniques impact symptomology in major depression. Kanter and colleagues (2010) conducted a review on behavioural activation techniques and unearthed a comprehensive typology and definition for each individual type, and summarized information regarding the optimal application of each technique. With regards to more cognitively focused interventions, there are extensive studies, and clinical resources on these therapeutic strategies as well; however, a comprehensive review similar to the one conducted by Kanter and colleagues does not appear to be readily available. The first two manuscripts address this gap and include a scoping review on cognitive interventions; given the vast literature, the cognitive restructuring CBT FOR MAJOR DEPRESSION: THERAPIST TECHNIQUE 8 review was separated into two manuscripts. Manuscript one examines cognitive techniques aimed at automatic thoughts, while manuscript two examines cognitive techniques that targeted core beliefs. In manuscript one, three overarching types of cognitive intervention were identified including: (1) identifying techniques, (2) exploring techniques, and (3) challenging or modifying techniques. Clinical recommendations related to the suggested effective delivery for these cognitive interventions were also extracted and summarized. In manuscript two, core belief techniques were identified and described including: (1) identifying techniques and (2) modifying techniques. This manuscript also identified recommendations across records that pertained to the delivery of the intervention in a clinical setting. In both manuscripts, clinical and research implications are suggested. In manuscript three, the aim was to conduct a systematic review of the studies that dismantled CBT into its components or techniques. The review compared cognitive interventions and behaviour activation interventions to comparators including combined cognitive-behavioural interventions, third wave interventions and controls. Given that meta-analyses and systematic reviews have been conducted, the review narrowed in on randomized control trials of interventions delivered individually and in a group context, for adults diagnosed with major depression and also explored the interventions impact on level of depression. Results indicated cognitive and behavioural interventions did not significantly differ, and highlighted the need for future studies that dismantle interventions
