BACKGROUND
The role of working alliance is largely unknown for internet-based interventions (IBI), an effective alternative for traditional psychotherapy.
OBJECTIVE
This study examined the conceptual invariance, trajectory, and outcome associations of working alliance in internet-based interventions incorporating or excluding clinician support via text or video.
METHODS
One hundred and forty-three adults with subclinical anxiety, stress, and/or depression symptoms were randomized to one of three treatment conditions for 7 weeks. All participants received access to MyCompass, an internet-delivered Cognitive Behavioral Therapy program. Participants in Condition 1 did not receive clinician support. Participants in Condition 2 and 3 received supplemental asynchronous clinician support via text or video respectively. Working alliance was measured weekly. Symptom outcomes were assessed at baseline, post-treatment, and 1-month follow-up.
RESULTS
We found scalar invariance of working alliance, indicating that working alliance was conceptually invariant across three conditions. Working alliance decreased significantly over time only in the text support group. Stronger baseline level and Faster increases in alliance predicted better outcomes at both post-treatment and follow-up only in the video support group.
CONCLUSIONS
Working alliance is methodologically comparable with or without clinician support and is generally established at initial sessions of IBI. Better alliance contributed to better outcomes only when clinician support is available via videos.
