“…In recent years, there has been a dramatic increase in the number of articles that stress the importance and urgency of systematic evaluation of mental health programs (e.g., Burgess, 1974;Rust, 1974;Windle, Bass, & Taube, 1974). In contrast, relatively few reports of completed evaluation projects have appeared in the literature (e.g., Mann, 1973;O'Neil et al, 1973;Tapp, Slaikeu, & Tulkin, 1973). Difficulties in implementing evaluation studies stem from the multiplicity and complexity of the goals and the services offered by mental health agencies.…”
