Behavioral activation (BA) treatments for depression require patients to increase overt behavior to bring them in contact with reinforcing environmental contingencies. This meta-analysis sought to identify all randomized controlled studies of BA, determine the effect of this approach, and examine the differential effectiveness of variants. Thirty-four studies with 2,055 participants reporting symptoms of depression were included.The pooled effect size indicating the difference between BA and control conditions at posttest was 0.78. For participants who satisfied the criteria for major depressive disorder, the overall effect size of 0.74 remained large and significant. No differences in effectiveness between BA and cognitive therapy were found. BA may be considered a well-established and advantageous alternative to other treatments of depression.

The capacity for a parent to self-regulate their own performance is argued to be a fundamental process underpinning the maintenance of positive, nurturing, non-abusive parenting practices that promote good developmental and health outcomes in children. Deficits in self-regulatory capacity, which have their origins in early childhood, are common in many psychological disorders, and strengthening self-regulation skills is widely recognised as an important goal in many psychological therapies and is a fundamental goal in preventive interventions. Attainment of enhanced self-regulation skills enables individuals to gain a greater sense of personal control and mastery over their life. This paper illustrates how the self-regulatory principles can be applied to parenting and family-based interventions at the level of the child, parent, practitioner and organisation. The Triple P-Positive Parenting Program, which uses a self-regulatory model of intervention, is used as an example to illustrate the robustness and versatility of the self-regulation approach to all phases of the parent consultation process.
