Development and Evaluation of Adherence Questionnaires for Gestalt Psychotherapy, Relational Transactional Analysis, and Integrative Psychotherapy: A preliminary investigation

This research involves the preliminary development and description of adherence questionnaires in Gestalt Psychotherapy, Relational Transactional Analysis and Integrative Psychotherapy, and the first evaluation of their validity and reliability. The analysis was conducted with 450 questionnaires used between 2011 and 2013, at a research clinic. It suggested that the adherence questionnaires for each of the approaches have a good level of internal consistency (α< 0.7) and construct validity. Factor analysis results suggested that the key construct examined by these measures was the practitioner’s ability to work within their therapeutic framework. This would be expected in a questionnaire on adherence (factors account for over 55% variation in scores), The “test-retest” reliability was not calculated due to difficulties in training the assessors, who were also the therapists’ clinical supervisors, and this test would be needed for further research into the consistency of the measures over time. Further testing and a refinement of the questionnaires would also be needed for different therapeutic environments and with different groups of therapists.

The project was completed in 2014.
