Abstract
Objective: To explore which cognitive behavioral therapy (CBT) self-help app usage predicted depression during a selective prevention trial.
Method: A recent controlled trial (ECoWeB-PREVENT) randomized young people aged 16-22, at increased risk for depression because of elevated worry/rumination, negative appraisals, and/or rejection sensitivity but without past or current history of major depression, to apps that provided self-monitoring, self-monitoring plus CBT self-help, or self-monitoring plus emotional competency self-help. Self-help included coping strategies for moment-by-moment use (Tools) and self-learning/planning exercises (Challenges). On the primary outcome (depression, Patient Health Questionnaire-9 [PHQ-9]) at 3-months follow-up (primary endpoint), only the CBT app outperformed self-monitoring. In this secondary analysis, only data from participants who used the CBT or self-monitoring apps at least once were analyzed to test what app use predicted change in depression from baseline to 3 months.
Results: Of the original 1,262 participants (79% female), 558 were included (CBT, baseline, n = 273, PHQ-9: M = 7.48, SD = 3.9; 3 months, N = 163, PHQ-9: M = 8.83, SD = 4.92; self-monitoring, baseline, n = 285, PHQ-9: M = 7.45, SD = 4.26; 3 months, N = 183, PHQ-9: M = 7.48, SD = 3.9). Neither total app use, self-monitoring, nor use of Tools predicted change in depression (all ps > .05). Frequency of use of Challenges predicted lower depression symptoms and caseness at 3 months (β = -0.28, 95% CI [-0.53, -0.03], p = .029). Specifically, the use of behavioral activation challenges mediated the effects of the CBT app on depression over 3 months (β = -0.59, 95% CI [-1.13, -0.05], p = .03).
Conclusions: Brief psychoeducation about behavioral activation principles in an app may protect young people from depression over 3 months, even when only used once. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
期刊介绍：
The Journal of Consulting and Clinical Psychology® (JCCP) publishes original contributions on the following topics: the development, validity, and use of techniques of diagnosis and treatment of disordered behaviorstudies of a variety of populations that have clinical interest, including but not limited to medical patients, ethnic minorities, persons with serious mental illness, and community samplesstudies that have a cross-cultural or demographic focus and are of interest for treating behavior disordersstudies of personality and of its assessment and development where these have a clear bearing on problems of clinical dysfunction and treatmentstudies of gender, ethnicity, or sexual orientation that have a clear bearing on diagnosis, assessment, and treatmentstudies of psychosocial aspects of health behaviors. Studies that focus on populations that fall anywhere within the lifespan are considered. JCCP welcomes submissions on treatment and prevention in all areas of clinical and clinical–health psychology and especially on topics that appeal to a broad clinical–scientist and practitioner audience. JCCP encourages the submission of theory–based interventions, studies that investigate mechanisms of change, and studies of the effectiveness of treatments in real-world settings. JCCP recommends that authors of clinical trials pre-register their studies with an appropriate clinical trial registry (e.g., ClinicalTrials.gov, ClinicalTrialsRegister.eu) though both registered and unregistered trials will continue to be considered at this time.
