Reliability and validity of the translated psychotherapy expectancy inventory

Matching treatment to therapy expectations is important. It increases treatment benefit and prevents dropout. No treatment expectation inventory existed in Hebrew, therefore a translation from English, of the Psychotherapy Expectancy Inventory-Revised, developed by Berzins, was undertaken. The questionnaire was given to 268 students twice, to 21 therapists and 107 parents of children referred to a child and adolescent clinic once. The translated questionnaire has high test-retest reliability, high internal consistency and significant criterion related validity-contrasted groups on advice, audience and relationship. Factor analysis yielded the four original scales, with the exception of two questions, which were moved to different scales.
