Comparison of outcomes between the intervention group (INT, n = 37) and control group (CTRL, n = 38) six weeks after treatment start, and within each group from baseline to six weeks.

TAS = Treatment alliance score, CSQ = Client satisfaction questionnaire, BASIS-32 = The behavior and symptom identification scale 32, PAM = Patient activation measure, MCS (SF-12) = Mental Component Score (Short form-12), PCS (SF-12) = Physical Component Score (Short form-12), ORS = Outcome rating scale, SRS = Session rating scale, PM = Patient motivation, PP = Patient participation.

A) The between-group mean differences for TAS, CSQ, SRS and PP have been calculated using two-tailed independent t-tests. The between-group estimated mean differences for BASIS-32, PAM, SF12, ORS, and PM have been calculated using analysis of covariance (ANCOVA), adjusted for baseline values.

B) The within group differences have been calculated using two-tailed paired t-test.

Decrease in score indicates improvement (less mental health symptoms) for BASIS-32. For the other outcomes, increased score indicates improvement.

* p-value ≤0.05.
