title: Process Evaluation of an Early-Intervention Program for Mood and Anxiety Disorders Among Older Adolescents and Young Adults.
abstract: OBJECTIVE
  Research to determine the best approach for providing early intervention for mood and anxiety disorders is imperative. The authors describe a process evaluation of an early-intervention program for transition-age youths with mood or anxiety disorders.
  
  
  METHODS
  Causal and logic models for pathways to care for the program, as well as descriptive data from 548 participating youths, are presented. Follow-up measures of functional improvement are reported.
  
  
  RESULTS
  Diagnostic characterization, symptom severity, and functional impairment of participants indicated that the model selected an appropriate catchment population without creating excessive overinclusion. Self-referred youths reported greater anxiety and substance use. Acceptance by the program was predictive of greater follow-through with treatment. Several variables, including frequent lifetime marijuana use, predicted loss to follow-up. At follow-up, youths were significantly functionally improved.
  
  
  CONCLUSIONS
  This process evaluation indicated that the model provided appropriate early intervention for youths with mood or anxiety disorders without causing excessive overinclusion.
