Internet-delivered psychotherapy for depression in adults.

PURPOSE OF REVIEW

The rapidly growing number of published research papers attests to the increasing interest in Internet-delivered psychotherapy (iPT). The present article reviews the current status of iPT for the treatment of adults with symptoms of depression.

RECENT FINDINGS

Randomized controlled trials have confirmed the efficacy of guided iPT in treating people with diagnosed or elevated symptoms of depression with equivalent results obtained by programs based on cognitive behavioural or problem solving models. With guidance, effect sizes are comparable to those obtained in face-to-face psychotherapy and low-intensity interventions are as effective as those with higher levels of therapist contact. On current evidence, entirely self-guided programs appear to have fewer benefits, but deliver tangible benefits to completers.

SUMMARY

Recent studies indicate the utility of iPT. Large-scale trials are needed to evaluate optimal strategies for disseminating iPT. Future studies should independently replicate findings and efforts are required to educate patients and health professionals about iPT.
