The study describes the development and validation of an instrument for measuring residential satisfaction in public housing: the ‘Residential Satisfaction Questionnaire for Public Housing’ (RSQPH). In the first phase, cognitive interviews were conducted to analyse the response process and comprehensibility of the preliminary version of the questionnaire. In the second phase, a pilot study was conducted on public housing residents within Costa Rica’s metropolitan area to gather initial evidence for nomological validity and internal consistency. In the final phase, the instrument was applied to 450 residents of 15 public housing developments, and further psychometric analyses were performed. The Exploratory Factor Analysis suggested a one-dimensional structure of the items, supported by a Confirmatory Factor Analysis that showed an adequate fit of the one-factor model to the data. The psychometric results showed that the instrument has adequate internal consistency, construct and nomological validity, indicating adequate psychometric properties to measure the construct.
