Comparing individually tailored to disorder-specific internet-based cognitive-behavioural therapy: benchmarking study.

Disorder-specific internet-based cognitive-behavioural therapy (ICBT) is effective for depression, panic disorder and social anxiety. In this benchmarking study, a new, individually tailored, ICBT programme (TAIL) showed effects on depression ( n = 284, d = 1.33) that were non-inferior to disorder-specific ICBT for depression in routine care ( n = 2358, d = 1.35). However, the hypotheses that TAIL for individuals with social anxiety or panic disorder is inferior to disorder-specific ICBT could not be rejected (social anxiety: TAIL d = 0.74 versus disorder-specific d = 0.81; panic: TAIL d = 1.11 versus disorder-specific d = 1.47). Our findings strengthen the empirical base for TAIL as an alternative to disorder-specific ICBT for depression.
