The current focus on community integration of individuals with psychiatric problems is attracting an increasing interest in the psychological literature, as it is regarded as a favorable factor in the recovery and for the well-being of these individuals. The Community Integration Scale of Adults with Psychiatric Disorders (CIS-APP-34) is a self-report scale developed to assess community integration in several dimensions. The main goal of the current study is to explore the psychometric properties of CIS-APP-34 in a sample of 411 participants with and without a psychiatric illness, with ages between 19 and 91 years old, living in the Azores Islands, Portugal. A confirmatory factor analysis was carried out to confirm the latent structure of the scale, and a five-factor model has presented good fit indices. Further analysis showed that the CIS-APP-34 is a measure with good reliability, validity and discriminant ability.
