The Potential Influence of Group Membership on Outcomes in Indicated Cognitive-Behavioral Adolescent Depression Prevention.

ABSTRACT: BACKGROUND:Adolescent depression prevention programs are typically delivered in groups in which adolescents share a common setting and interventionist, but the influence of the group is usually ignored or statistically controlled. We tested whether the primary outcomes of reductions in depressive symptoms and future onset of major depressive disorder (MDD) varied as a function of group membership. METHODS:Data were available from two randomized trials in which 220 adolescents received the Blues Program indicated prevention intervention in 36 separate groups; participants were assessed at baseline, post intervention, and at 6-, 12-, and 24-month follow-ups. RESULTS:Ten percent of participants had developed MDD 2 years post intervention. Group-level effects for MDD onset over follow-up were nonsignificant (accounted for <1% of variance; ICC = 0.004, ns). Group-level effects for depressive symptom change across the follow-up period were also nonsignificant (ICC = 0.001, ns) but group effects accounted for 16% of depressive symptom change immediately post intervention (ICC = 0.159, p < 0.05). Group-level clustering of posttest depressive symptoms was not associated with size of group or gender composition. CONCLUSIONS:Membership in specific adolescent cognitive-behavioral depression prevention groups may have an impact in terms of immediate symptom reduction but does not appear to have significant prevention effects in terms of long-term symptom change or MDD onset.

Project description:BackgroundTo reduce the large public health burden of the high prevalence of depression, preventive interventions targeted at people at risk are essential and can be cost-effective. Web-based interventions are able to provide this care, but there is no agreement on how to best develop these applications and often the technology is seen as a given. This seems to be one of the main reasons that web-based interventions do not reach their full potential. The current study describes the development of a web-based intervention for the indicated prevention of depression, employing the CeHRes (Center for eHealth Research and Disease Management) roadmap. The goals are to create a user-friendly application which fits the values of the stakeholders and to evaluate the process of development.MethodsThe employed methods are a literature scan and discussion in the contextual inquiry; interviews, rapid prototyping and a requirement session in the value specification stage; and user-based usability evaluation, expert-based usability inspection and a requirement session in the design stage.ResultsThe contextual inquiry indicated that there is a need for easily accessible interventions for the indicated prevention of depression and web-based interventions are seen as potentially meeting this need. The value specification stage yielded expected needs of potential participants, comments on the usefulness of the proposed features and comments on two proposed designs of the web-based intervention. The design stage yielded valuable comments on the system, content and service of the web-based intervention.ConclusionsOverall, we found that by developing the technology, we successfully (re)designed the system, content and service of the web-based intervention to match the values of stakeholders. This study has shown the importance of a structured development process of a web-based intervention for the indicated prevention of depression because: (1) it allows the development team to clarify the needs that have to be met for the intervention to be of use to the target audience; and (2) it yields feedback on the design of the application that is broader than color and buttons, but encompasses comments on the quality of the service that the application offers.
