A total of 172 individuals diagnosed with a schizophrenia spectrum disorder were followed for 36 months in 3 distinct models of community-based care. Functional outcome data gathered every 6 months were combined with service implementation data to test hypotheses concerning the impact of service characteristics on prospective client outcomes. The results using hierarchical linear modeling supported associations between the intensity, specificity, and longitudinality of services and improved client outcomes. Specifically, more intense services were associated with higher levels or rates of improvement on all indices of clinical and psychosocial functioning. The specificity results suggested that services needed to be targeted to specific areas of functioning in order for improvement to occur. The effect of longitudinality was contingent on the outcome domain examined.
