CBT emphasises the important role of thinking in how we feel and how we behave. CBT aims to identify and modify maladaptive thought processes and behaviours through cognitive restructuring and behavioural techniques to achieve change. There is considerable evidence supporting the use of CBT for the treatment of depressive, anxiety, and AOD use disorders [695–697] delivered in a variety of formats (e.g., in-person, multimedia, online) [696, 698]. Appendix BB describes a number of CBT techniques that may be used in the management and treatment of mental health and AOD use conditions, including cognitive restructuring, pleasure and mastery events scheduling, goal setting, and problem solving. A more detailed discussion of CBT may also be found in Baker and colleagues [699] and Graham [700]. A number of the interventions designed for specific co-occurring disorders, such as Seeking Safety (for PTSD and substance use [701, 702]) and Dual Focus Schema Therapy (for personality disorders and AOD use [703, 704]), are in part based on these CBT techniques Interventions for specific co-occurring conditions are discussed in more detail in Chapter B7.
