A self-management measurement: Validity of the Partners in Health Scale (PHS) instrument in Peruvian elderly population

The Partners and Health Scale Instrument has been validated in several countries, however, it has just been applied in Spanishspeaking countries to people with chronic conditions, allowing a self-management evaluation with wide clinical application and research. It is the first time it has been applied in elderly patients (60 or older) in Spanish-speaking countries. This study shows the instrument validity in this population - users of health services of the Ministry of Health in Lima-Peru. An intentional non-probabilistic sample of 152 subjects with Construction Validity was performed: 1) Factor Analysis and 2) Confirmatory with structural equations and Reliability: Cronbach’s Alpha presents construct validity in three factors with an explained variance of 0.597. From the results of the goodness of fit model measures obtained by AMOS 24.0 and FACTOR 10.10, it can be seen that 6 of the 7 measures obtained are acceptable. The reliability with the Cronbach Alpha coefficient was 0.845. Although the model may have high-quality goodness of fit, the possibility of another alternative model that meets a better fit cannot be rejected; the results allow us to conclude that this Instrument presents validity and reliability in the evaluation of self-management within three factors.
