The impression gotten from reading the article is that the authors’ primary interest was to compare the two treatment methods in terms of durability and generalizability of the skills acquired during the treatment sessions. The treatment conditions and durations were comparable, except for the provider characteristics. Three certified occupational therapists provided the treatment for the "psychosocial group," whereas one occupational therapist (certification status not reported) and two paraprofessionals provided the treatment for the "skills training group." The information on the role of the occupational therapist in the latter group was lacking, as was the background information of the so-called "paraprofessionals." In order to compare the clinical skills of paraprofessionals and occupational therapists, many additional variables should be taken into consideration, such as educational background, hours of training, and job experience. These were not addressed in the article.
