Validation of the PACER-PT: a measure of health-relevant perceptions of gentrification-related neighbourhood change

PACER-PT, a Portuguese adaptation of the PACER scale, identifies a three-factor structure for gentrification-related neighbourhood change in Lisbon and Porto, explaining 47.5% of variance.

• Why it matters: Health impacts of gentrification-related neighbourhood transformation are increasingly recognized, but validated tools to measure residents’ perceptions in Portugal are scarce.
• What they did: A cross-sectional online survey of 255 adults living in the Lisbon and Porto Metropolitan Areas for at least 5 years was used to translate PACER into PACER-PT and test psychometrics with EFA, Cronbach’s alpha, and convergent/criterion validity.
• The result: PACER-PT showed acceptable internal consistency (Cronbach’s alpha=0.70-0.78) and significant associations with amount and pace of change, self-rated health, and quality of life, supporting its use in Portugal.
