Adolescent internet depression prevention: Preferences for intervention and predictors of intentions and adherence

Adolescents in primary care with sub-threshold depression (not reaching criteria for disorder) symptoms may be candidates for early intervention to prevent the onset of major depressive disorder. However, we know little about their attitudes toward such interventions or what may predict motivation or adherence for preventive interventions. We also describe preferences for different types of interventions and conduct exploratory analyses to identify predictors of motivation to prevent depression and subsequent adherence to an Internet-based intervention. Adolescents with sub-threshold depressed mood favored novel behavioral treatment approaches, such as Internet-based models for depression prevention. Adolescent beliefs about the intervention and perceived social norms predicted intention to participate in depression prevention. The most important significant predictors of adherence were beliefs about the intervention. Careful attention to the specific beliefs and attitudes of users toward intervention should be incorporated into intervention design as well as evolving public health strategies to prevent depressive disorders.
