This study aimed at evaluating usability, functionality and initial effects of a computerized psychoeducational intervention directed at Obsessive-Compulsive Disorder (OCD), through a usability trial with users. Twenty-one users ranging from 19 to 55 years old took part in the study. Measures were Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), subjective scales to assess OCD symptoms intensity, mood and anxiety, usability questions, and the system log. Participants took an average of eight days to complete the intervention, and the average time of software usage was 2 hours and 14 minutes. Only one quiz question showed less than 70% correct answers. Mean level of satisfaction was 8.33 for the first module, 8.71 for the second and 9.00 for the third. There was a decrease in Y-BOCS obsessive scores, and a statistically significant difference was found on the scale of OCD symptoms intensity, between modules 1 and 2, and 1 and 3. The software reached a good level of satisfaction among users and shows potential in reduction of perceived symptoms. It is argued that, as a template, the program can contribute both practically and theoretically for novel applications in the interface of psychotherapy and technology.
