"Data Trends" reports present summaries of research on mental health services for children and adolescents and their families. The article summarized in this "Data Trends" sought answers to several questions of central importance in understanding why maintaining employment is so challenging to these youth, and in designing transition programs and employment interventions that address those challenges. The questions are: (1) To what extent does the job performance of youth with EBD match the expectations of their worksite supervisors? (2) Do ratings of these youths' performance on key work behaviors differ between supervisors and youth themselves? (3) Do ratings of the importance of these same work behaviors differ between youth with EBD and their supervisors/employers? and (4) How satisfied are youth with EBD with certain aspects of their employment situation? The findings that many youth with EBD may not be meeting the expectations of their immediate supervisors, and that their perceptions of their on-the-job performance are generally higher than those of the supervisors charged with evaluating their work, can help to explain some of the frustrations, barriers to advancement, and high turnover experienced by these youth. Youth employment outcomes may improve from direct instruction on how to identify and maintain acceptable work performance standards, as well as provision of secondary school programs that cultivate the skills most important to job success. Also, it is important to recognize that desired work behaviors vary among job sites; a means of identifying which skills (for an individual youth within a given employment setting) need to be targeted for intervention is necessary. A questionnaire like the one used in this study may serve this purpose. Finally, the study highlights the need for effective, but non-stigmatizing, support and training in employment settings.
