Psychometric Properties of the Brazilian Version of the Revised Illness Perception Questionnaire for Healthy Women (IPQ-RH)

The Common Sense Model refers to the association between disease perception and health behaviors. This study aimed to analyze the psychometric properties of the Revised Illness Perception Questionnaire for Healthy People - (IPQ-RH) in healthy women about breast cancer. A total of 321 women participated, with a mean age of 55.72 years old (SD = 10.75), users of Basic Health Units. Confirmatory factor analyzes (CFAs) were carried out and the McDonald’s Omega and Cronbach’s alpha coefficients were calculated. The results of the CFAs confirmed the structure of seven factors for the IPQ-RH (CFI = .92; TLI = .91; RMSEA = .03; SRMR = .06) and of two factors for the subscale of causes of the disease (CFI = .97; TLI = .97; RMSEA = .00; SRMR = .05). The instrument’s reliability was, in general, satisfactory. The IPQ-RH has appropriate psychometric properties to investigate the illness perception in healthy women.
