Directorial leadership	0.983	0.045	0.899, 1.075	1.006	0.005	0.995, 1.016

Note. Organizational climate, a subscale of readiness for change, was not included because it was correlated with staff attributes at 82%. We adjusted for program-level variables (private insurance, organizational cultural competence, public health services, and public funding) and client-level variables (gender, mental illness, homeless, Medi-Cal eligibility, referral type, race, and treatment type).
