Vulnerability to physical inactivity: content validation of markers for adults

Abstract

Objective: To validate the content of markers of vulnerability to physical inactivity in adults. Methods: This is a methodological study, based on psychometrics, which aims to develop constitutive and operational definitions of markers of vulnerability to physical inactivity in adults and content validation by experts. Data were analyzed by calculating Content Validity Index (CVI) and binomial test. Results: Thirteen judges, health professionals, researchers with publications on the subject, from seven Brazilian states (Ceará, Pernambuco, Piauí, Bahia, Amazonas, Santa Catarina and Rio de Janeiro), participated in the validation. A total of 40 markers were validated, with 40 constitutive definitions and 133 operational definitions. These were grouped into two interrelated dimensions (subject and social) and 12 subdimensions (physical situation, psycho-emotional situation, behavior, functional literacy, interpersonal relationships, sociodemographic profile, environment, policies, institutional context, culture, fundamental rights). All had excellent CVI (≥ 0.78). Conclusion: The proposed markers presented adequate parameters of validity and can be used to operationalize the measurement of vulnerability to physical inactivity phenomenon in the construction of instruments and strategies for patient care and coping with physical inactivity.
