title: The Helping Alliance Questionnaire: psychometric properties in patients with substance dependence.
abstract: Psychometric properties of the Helping Alliance Questionnaire (HAQ) are analyzed in a population of 340 substance-dependent patients of an addiction clinic in the Netherlands. Factor analysis yields a two-factor structure: Cooperation and Helpfulness. The scales show fair correlations with three out of seven scales from the Barrett-Lennard Relationship Inventory. Length of Stay in Detox is predicted by scores on the Helpfulness scale and noncompliance by scores on the Cooperation scale. Besides this, intermediate outcome measures are correlated with HAQ scores. The HAQ seems to be a "quick scan" instrument to give a quick and global impression of the patients' perception of the quality of the working alliance with the therapist.
