A test of the phase model of psychotherapy change

Can J Psychiatry. 2002 Oct;47(8):759-66. doi: 10.1177/070674370204700807.

Abstract

Objective: A comparative trial of 2 forms (interpretive and supportive) of short-term, time-limited individual (STI) therapy provided data that were used to test the propositions of the Howard and others phase model of psychotherapy change.

Method: Patients completed the Integra Outpatient Tracking Assessment Form on 5 occasions during the 20-session treatments. The measure assesses 3 dimensions: subjective well-being, current symptoms, and current life dysfunction. Howard and others regard these as dimensions that represent successive phases in the therapy change process (that is, well-being improves first, followed by resolution of symptoms, and finally by change in long-standing life dysfunction). We conducted a test of their model, using their approach to data analysis.

Results: The comparative trial data provided no support for the phase model.

Conclusions: Possible explanations for the absence of confirmatory findings are considered.
