The Chinese Version Of The Oq-45.2 Reliability And Validity Of Applications

With the rapid development of the field of counseling psychology, the quality of psychological counseling is becoming an important element of the psychology study. Some researchers have already used standardized scales to monitor outcome. Outcome Questionnaire (OQ-45.2) is developed by Professor Lambert M.J. from Brigham Young University of U.S.A., now it is one of the widely used outcome measure tools. Based on introducing the OQ-45.2 and partially revised, this study inspects the reliability and validity of the OQ-45.2, establishes the standard of the outcome evaluation and standardized implementation procedure, it also tastes the initial discussion for the symptom trend of the clients after counseling.The sample consists of 536 counseling center clients from Jiangsu and Zhejiang Provinces, 230 community members from Zhejiang Province and 1759 university students from Jiangsu, Zhejiang and Anhui Provinces. It is used to inspect the reliability and validity of the Chinese version OQ-45.2 and establish the standard of outcome evaluation and standardized implementation procedure. Furthermore, 41 clients of the sample who have integrated counseling record are used to study the symptom trend after counseling.The results as following:(1)The revised OQ-45.2 theory structure corresponds with the Three Factor Model proposed by Lambert, it has high reliability and good validity, and can be widely used to measure outcome in psychological counseling agencies.(2) According to the Clinical Significance concept proposed by Jacobson et al, the cutoff for the Chinese version of OQ-45.2 total scale and symptoms distress, interpersonal relationships, social role subscales are 61/62, 33/34, 14/15 ,14/15 respectively, RCI are 17,11,5,4, respectively. Compare the indices to the English version of OQ-45.2, the two cutoffs are similar but there's some difference between the two RCIs . Then evaluating criterion which classifies clients into recovered, improved, no changed as well as deteriorated, and standardized implementation procedure were developed. We also found that assisted with computer can effectively improve accuracy of outcome information.(3) Chinese version of OQ-45.2 studies the symptom trend after counseling for 41 clients who had 3 counseling sessions on average. It indicates that clients'symptom distress got improved before interpersonal relations and social role performance; this is corresponding with the three phase model by Howard.In conclusion, Chinese version OQ-45.2 has high reliability and good validity. The evaluating criterion and standardized implementation procedure it builds could help the outcome research and it's practical application.
