Measures of the Therapeutic Relationship in Severe Psychotic Illness: A Comparison of Two Scales

In: The international journal of social psychiatry, Band 52, Heft 3, S. 256-266

Abstract

Background: A durable therapeutic relationship is central to mental health practice. The Working Alliance Inventory (WAI) and the Helping Alliance Questionnaire (HAQ) are established instruments for measuring such a relationship. Aims: The project aimed to test the correlation between the two scales for patients with severe psychotic illness treated in an Assertive Community Treatment (ACT) team. Methods: Ninety-one patients of an ACT team and their key-workers were recruited to complete the measures. Results: Seventy-one patients (78%) completed the scales, and key-workers completed scales for every eligible patient. Both groups rated the relationship positively. There was a strong and significant correlation between the patient version of the WAI and the HAQ. There were significant but much weaker correlations between the patient-rated WAI and HAQ and the key-worker WAI. Conclusion: The patient version of the WAI and the HAQ seem to measure the patient's view of the relationship equivalently. The HAQ is simpler and easier to administer than the WAI.
