title: Reliability and validity of a treatment adherence measure for child psychiatric rehabilitation.
abstract: OBJECTIVE
  Treatment adherence, defined as the degree to which practitioners implemented prescribed program principles and activities and avoided proscribed activities, has been an area of growing interest in mental health services for children with severe emotional and behavioral disorders. This study evaluated the reliability and validity of a treatment adherence measure for child psychiatric rehabilitation (CPSR).
  
  
  METHODS
  Parents of children receiving CPSR (n = 79) or psychotherapy (n = 27) completed the Children's Psychosocial Rehabilitation Treatment Adherence Measure (CTAM) and a measure of 2-week session impact. Psychiatric rehabilitation (PSR) supervisors identified PSR practitioners with reputations for high or low adherence to the model. The CTAM's discriminant validity was assessed by using known-groups procedures and predictive validity by examining its relationship to 2-week session impact.
  
  
  RESULTS
  The CTAM demonstrated excellent internal consistency (α = .92), discriminant validity (p = .002, d = .72; p = .021, d = .59), and predictive validity (B = 2.24, SE = .31, p < .001), accounting for 28% of the child-level variance in 2-week session impact.
  
  
  CONCLUSIONS
  Findings suggest the CTAM is a reliable and valid measure of treatment adherence for CPSR programs with a skill-teaching focus. Providers and agencies should take steps to enhance treatment adherence because it may be an important predictor of children's short-term response to CPSR.
