Assessing Continued Employability among People with Mental Illnesses: Development of a Scale in Japan

Continued employment enables people with mental illnesses to maintain and improve their mental health, and its mutual understanding between them and their workplaces can help provide specific support and improve the work environment. Hence, this study developed a Continued Employability Scale to provide people with mental illnesses solutions for achieving continued employment and examined the scale's reliability and validity. It is based on a conceptual analysis of the skills necessary for continued employment and comprises items related to continued employability and the consequences of continued employment. We performed conceptual analyses to prepare the item list, conducted the study using a questionnaire survey, and examined its content validity and reliability using factor analyses. The results showed that the developed scale, which can determine self-management, dedication to work, environmental adjustments, and expression of sincerity necessary for continued employment, was reliable and valid. This can be a potentially helpful tool for assessing the ability to continue working and help people with mental illnesses visualise their continued employability, clarify what is being assessed, and improve the self-management ability necessary for continued employment. Further, it can help people who support them at work and enable existing support and programs to function effectively.
