N = 335 clinicians (n = 154 working in outpatient mental health, n = 181 working in assertive community treatment). Models estimated using robust maximum likelihood estimation; S-B Scaled χ² Δ, Satorra-Bentler Scaled Chi-Square Difference test
CFI Comparative fit index, EBCSS Evidence-based Clinical Supervision Strategies scale, RMSEA Root mean square error of approximation, SRMR Standardized root mean square residual
^aThe intercept for Item 2 (“supervision included feedback about practice based on data about the people I serve”) was allowed to vary freely across groups; all other intercepts and factor loadings constrained equal
