Abstract Aim To support the achievement of life goals and social participation of persons with mental illness, based on the World Health Organization's International Classification of Functioning, Disability, and Health (ICF), we generated items, identified domains, and examined the content validity of the Comprehensive Assessment of Functioning for Mental Illness‐Subjective Version (CAMI‐S). The purpose was to assess patients' strengths and weaknesses by incorporating the patient and public involvement perspective. Methods Focus group interviews on the items to be included were conducted with Group A. A draft scale was constructed by extracting articles mentioning factors for social participation and recovery for each ICF component from PubMed. Group B participants rated themselves using the draft and highlighted items they considered inappropriate. Experts then rated the importance of the items through the Delphi method. Lastly, Group C participants evaluated whether the draft scale would help in understanding their strengths and weaknesses. Results The interviews revealed subjective experience items. The draft scale had 81 items (physical and mental functions, 10; activities, 23; participation, 24; environment, 12; individuals, six; and subjective experience, six). Through the Delphi method, the number of items was reduced to 34 in six domains. Most participants (N = 50) indicated that it helped them ascertain patients' strengths and weaknesses (mean = 2.11 ± .714). Completion time for the scale was 56 min, including the 60‐item face sheet (20–110 min). Conclusion The CAMI‐S helped participants ascertain patients' strengths and weaknesses. Its reliability and validity will be verified through a large‐scale survey in the future.
