OBJECTIVE: Blended care (BC), the integration of Internet-based interventions into psychotherapy (PT), is thought of as a promising approach to enhance PT's effectiveness and efficiency. This randomized controlled trial aimed to investigate the effectiveness as well as the implementation and usage of BC with transdiagnostic online modules compared to PT in routine care in Germany. Routine outpatient PT is delivered by licensed psychotherapists across different therapeutic orientations (cognitive behavioral therapy, psychodynamic, systemic), with variable treatment lengths and procedures.
METHOD: Psychotherapists in routine outpatient care recruited 1,159 patients who were randomized to BC or PT. The primary outcome was self-reported mental distress (the composite of anxiety and depression); secondary outcomes included self-reported satisfaction with life, level of functioning, eating pathology, and drug and alcohol use, as well as therapist-rated severity and changes. Outcomes were measured at baseline, 6 weeks, 12 weeks, 6 months, and 12 months. We examined whether BC and PT groups changed differently over time using linear mixed models. We also investigated differences in sessions and terminations and report usage metrics of the BC platform.
RESULTS: Contrary to our hypotheses, we did not find differences between BC and PT in outcomes, including anxiety, depression, satisfaction with life, level of functioning, eating pathology, alcohol and drug use, therapist-rated severity, and satisfaction with treatment at 6 months postrandomization (all p > .05). BC and PT did not differ in the number of sessions or terminations. Regarding usage of the BC platform, 534 patients (91.6%) received at least one online chapter, with M = 7.26 (SD = 7.01) of a total of 39 online chapters assigned on average, and patients logged in M = 19.73 (SD = 24.66) times and spent M = 367.14 (SD = 338.27) minutes on the platform.
CONCLUSIONS: In this real-world application of BC, therapists had considerable flexibility in implementing BC and integrating Internet-based interventions with sessions. Our findings suggest that the benefits observed in more structured BC setups may not fully translate to a flexible and transdiagnostic BC setup in routine care, potentially due to variations in implementation and adherence.
