Introduction & Theoretical Background
Learning theories propose that depression is the result of losing touch with sources of positive reinforcement: falling into habits of inactivity (or the wrong kinds of activity) lead to a lowering of mood. Once people feel depressed they may lack motivation, become less active, experience less positive reinforcement, and the cycle repeats or exacerbates. A behavioral approach to overcoming the vicious cycle of depression is to increase one’s level of activity even in the absence of feelings of motivation. This approach is called behavioral activation (BA) and there is strong evidence that it is an effective treatment for depression (Ekers et al, 2014), with equivalent effect sizes to treatments such as cognitive therapy (Jacobson et al, 1996). Modern approaches to BA include Martell, Addis & Jacobson’s package Depression in context: Strategies for guided action (2001), and Lejuez, Hopko & Hopko’s package Brief Behavioral Activation Treatment For Depression (BATD: 2001).
