Construction and validation of the “Eight natural remedies” questionnaire - Adventist life style

Objectives: To construct and validate the Eight Natural Remedies Questionnaire, in adult and adolescent versions, to assess adherence to healthy habits that are considered to be constitutive of the Seventh-day Adventist lifestyle. It is a conceptual, descriptive, involving 20 judges who participated as experts in analyzing the construct. The domains are: nutrition, exercise, water, sunlight, temperance, air, rest and trust in God. Results: The meanings, dimensions and descriptors of the "lifestyle" construct with 25 items and eight domains were identified, as well as reliability measures of the construct analysis (Cronbach's alpha = 0.90) and the questionnaire pilot test for adults and adolescentes were Cronbach's alpha = 0.75 and 0.67 respectively. The percentage of agreement on the characteristics of the instrument was above 80% in the last applications, and the content validity index for the same characteristics were also above 0.8. Conclusion: The instrument presents evidence of validity regarding the content to be applied, especially to the population of participants of the Health Fairs, for both adults and adolescents. Measures of validity and reliability have attained adequate indexes and are considered to be a content-valid instrument, which corresponds to Ellen White's proposal for lifestyle advocated by Seventh-day Adventists to promote health.
