Background: web-based interventions for individuals with depressive disorders have been a recent focus of research and may be an effective adjunct to face-to-face psychotherapy or pharmacological treatment. objective: the aim of our study was to examine the early change patterns in web-based interventions to identify differential effects. methods: we applied piecewise growth mixture modeling (pgmm) to identify different latent classes of early change in individuals with mild-to-moderate depression (n=409) who underwent a cbt-based web intervention for depression. results: overall,three latent classes were identified (n=409): two early response classes (n=158,n=185) and one early deterioration class (n=66). latent classes differed in terms of outcome (p<.001) and adherence (p=.03) in regard to the number of modules (number of modules with a duration of at least 10 minutes) and the number of assessments (p<.001),but not in regard to the overall amount of time using the system. class membership significantly improved outcome prediction by 24.8% over patient intake characteristics (p<.001) and significantly added to the prediction of adherence (p=.04). conclusions: these findings suggest that in web-based interventions outcome and adherence can be predicted by patterns of early change,which can inform treatment decisions and potentially help optimize the allocation of scarce clinical resources.
