Figure 2. Model-Estimated Match Effects on Change in Severity of General Impairment During Treatment Among 218 Mental Health Care Patients.

Patients in the matched group experienced significantly greater reductions in general impairment compared with patients in the case assignment as usual (CAU) condition across 17 weeks (16 weeks of treatment and 1 baseline week). In terms of overall impairment severity, a score of 0 represents the mean level of impairment shown by non–treatment-seeking individuals in the community. Therefore, a score of 1 represents an impairment level that is 1 SD higher than the community mean and a score of −1 represents impairment that is 1 SD lower than the community mean.
