Distinguishing specific from nonspecific interventions in comparative outcome studies: reply to Collins and Thompson. Academic Article uri icon


  • Collins and Thompson (1988) challenged the utility of such labels as behavioral and insight-oriented in comparative therapy research and questioned the manner in which these theoretical approaches were operationalized in a recent study by Wills, Faitler, and Snyder (1987). We argue that such labels, while imperfect, identify the context in which theory-driven models of clinical intervention are tested. Psychotherapy research requires that specific and nonspecific components of treatment approaches be distinguished. The study by Wills et al. provides a model for verifying therapist fidelity in manual-guided treatment research.
