ABSTRACT
Background:
Blended care psychotherapy, which combines the strengths of therapist-led and Internet interventions can be clinically effective and efficient but has been rarely evaluated outside of controlled research settings.
Objective:
This study evaluated the effectiveness of a blended care intervention (video-based CBT and Internet intervention) under real world conditions.
Methods:
This is a retrospective analysis of 385 participants with clinical range depression and/or anxiety at baseline (measured using the PHQ-9 and GAD-7) who enrolled in blended care psychotherapy treatment. Levels of depression and anxiety symptoms were tracked over the course of treatment and rates of reliable clinical change and clinically significant improvement were analyzed.
Results:
Approximately 73% (n = 283) of all 385 participants demonstrated reliable improvement and 83% (n=319) recovered on either the PHQ-9 or GAD-7 measures. Large effect sizes were observed on both symptoms of depression (Cohen’s d = 1.08) and of anxiety (Cohen’s d = 1.33).
Conclusions:
Video CBT blended care interventions can be effective and efficient in treating symptoms of depression and anxiety in real world conditions. Future research should investigate the differential and interactive contribution of the therapist-led and digital components of care to patient outcomes to optimize care.
