Results indicated that the match effect on weekly symptomatic/functional impairment reduction was more pronounced for therapists who treated a higher proportion of patients with primary substance misuse or violence ( γ 101 = − 0.09, SE = 0.04, p = 0.022), though this interactive effect was only a nonsignificant trend for posttreatment symptomatic/functional impairment level ( γ 011 = − 1.20, SE = 0.60, p = 0.052).
