The assessment of well-being is crucial for measuring the effects of psychosocial interventions in people with intellectual disabilities. The aim of this study was to adapt and validate a measure of integrative well-being, the Pemberton Happiness Index (PHI) to use it specifically for this population. Methods. The Pemberton Happiness Index was first tailored to individuals with intellectual disabilities (PHI-Intellectual Disabilities). Then a sample of 130 adults with mild-moderate intellectual disabilities completed this adapted version alongside other well-being and affective measures. Results. The psychometric properties of this new PHI-Intellectual Disabilities were shown to be very good (i.e., internal consistency, convergent and incremental validity). Conclusion. The study provides initial evidence of the reliability and validity of a brief measure of well-being that can be used for both applied and research purposes specifically for adults with mild-moderate intellectual disabilities.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article1931-5872https://doi.org/10.1080/19315864.2022.2098431open accessPsychological well-beingQuality of lifeIntellectual disabilitiesMeasurementPsicología (Psicología)6105 Evaluación y Diagnostico en Psicología
