Abstract:Motivational Interviewing (MI) is known to be a well-proven behavior change technique in face-to-face treatments. The Motivational Interviewing Skill Code (MISC) is an instrument to measure the treatment integrity of counselors applying MI in face-to-face treatments. MI is also applied in web-based treatments, but an instrument to measure treatment integrity does not exist for web-based treatments. The aim of this study is to validate the MISC and to make it more feasible for asynchronous communication in web-based interventions. After it was concluded that the MISC is feasible as it is, the MISC was applied to nine cases. It is expected that the MI-consistency measure can predict treatment outcome. This analysis is being conducted in three different ways. To gain insight in the relevant major differences for applying the MISC in web-based interventions an analysis based on the MISC-summary scores is applied. There is a significant strong negative correlation (r = -.84, n = 9, p = <.01) between the Percentage MI-Consistent Responses and the treatment outcome. This result is found to be consistent after comparing three different treatment outcomes with the MI-consistency. Although the counselors are compared with counselors applying MI in face-to-face, the counselors from these nine cases score as a beginner according to the MISC-summary scores. From this perspective the MISC is not a valid instrument for predicting treatment outcome, nor is it feasible in its current state. It is recommended to make methodological improvements to modify the MISC into a more feasible and valid measure instrument for measuring treatment integrity in web-based interventions.
