The purpose of this study was to create a guide regarding assistance by the Re-work program for users with autistic traits, who were not diagnosed with autism spectrum disorder during childhood, but exhibited the triad of impaired social interaction, communication, and imagination. Input to create the guide was gathered from experienced Re-work program staff and child psychiatrists. The guide advises Re-work program staff to refrain from diagnosing the patients, and thus prevents excessive diagnosis of autism spectrum disorder or developmental disorder, and encourages the staff to carry out individual sessions to assist with the patients' self-understanding and self-awareness. A survey on the usefulness of this guide was carried out at 28 Re-work facilities, and 27 staff of 26 facilities replied. In the survey, the guide was assessed based on " understandability" " usefulness in identifying users who need assistance" " ease of providing assistance without discussion on diagnosis" " usefulness for staff" " usefulness for users with autistic traits" and " usefulness at the workplace" using a 4-point Likert scale. The averages of these items were 3.37, 3.31, 3.04, 3.22, 3.08, and 2.85, respectively. Understandability of the guide and its usefulness in identifying users who need assistance were highly rated, whereas its usefulness for users with autistic traits was considered questionable. Provision of assistance without discussion on diagnosis was considered difficult. Furthermore, a separate guide may be necessary for the workplace. The current diagnostic criteria for autism spectrum disorder are not applicable to the population who did not exhibit noticeable maladjustment in structured life during childhood, but exhibit substantial maladjustment when exposed to higher stress in adulthood. The difficulties that adults with autistic traits experience are not well known or understood by childhood autism specialists. Therefore, collaboration between autism specialists and staff who assist maladjusted adult patients, such as Re-work program staff, is necessary.
