Although administrative bodies such as community health centers have implemented various awareness campaigns to promote community understanding of mental health and to reduce the stigma associated with mental illness and disorder, there have been few reports that have quantitatively analyzed the effects of these campaigns in Japan. Therefore, this study was conducted for the purpose of developing the evaluative “Mental Illness and Disorder Understanding Scale (MIDUS)” for awareness campaigns and assessing its reliability and validity. A survey was conducted on 1 004 community residents using a self‐administered questionnaire. An assessment of the reliability and validity of the scale was then conducted. The Cronbach a coefficient of the MIDUS was 0.78, thus indicating adequate reliability. Factor analysis of the MIDUS revealed three factors: “Treatability of illness”, “Efficacy of medication” and “Social recognition of illness”. In addition, a significant correlation was observed between the MIDUS and existing scales, and fixed criterion‐based validity was demonstrated. The MIDUS utilizes items worded in the form of affirmative expressions so as to avoid promoting new bias. It was confirmed to be both reliable and valid, thereby suggesting its usefulness as an evaluative scale of awareness campaigns.
