Is follow-up necessary in evaluating psychotherapy?
Examines the assumption that conclusions drawn at follow-up may differ from conclusions made at the end of therapy for neurotic patients. Follow-up research is quantitatively reviewed to evaluate empirically whether outcomes at posttreatment differed from outcomes at follow-up. Results demonstrate that information obtained at follow-up often added little to that obtained at the end of treatment. Findings highlight the general durability of gains achieved during psychotherapy, suggesting that costly follow-up procedures may be used more selectively.
