The aim of this study was to evaluate the effectiveness of video modelling in teaching hotel house-keeping skills to adults with intellectual disabilities and to assess the acquisition of video-based non-target information. A multiple probe across behaviours design was used. 4 adults with intellectual disabilities participated in the study. Baseline, probe, intervention, maintenance and generalization sessions were conducted. Results indicated that video modelling was effective in teaching hotel house-keeping skills to adults with intellectual disabilities. Moreover, the acquired hotel house-keeping skills were maintained over time and generalized across settings and materials. The assessment of video based non-target skills data showed that participants acquired the non-target information with the range from 33% to 100%. In conclusion video modelling can be used effectively in teaching vocational skills to adults with intellectual disabilities.
