Utilization and Content Validity of the Swedish Version of the Volitional Questionnaire (VQ-S)

Abstract

The aim of this study was to examine the utility and content validity of the Swedish version of the Volitional Questionnaire (VQ-S). The participants in this study were thirteen occupational therapists selected because they worked with clients for whom the VQ-S is appropriate (in this case, adults with intellectual impairments) and because they had knowledge of the Model of Human Occupation. These participants completed a demographic questionnaire at the beginning of the study. Each therapist then used the VQ-S a total of six times and after each time they completed a questionnaire concerning the utility and content validity of the instrument. After having administered the instrument six times they completed a third questionnaire that assessed their perceptions of the VQ-S based on their total experience. Data from these questionnaires and the six assessment forms with the actual client ratings were analyzed using both quantitative and qualitative procedures. The findings indicate that the VQ-S has clinical relevance and potential for implementation with adults with intellectual impairments. They also support the content validity of the VQ-S.
