Background:
The transtheoretical model (TTM) has been widely used to promote healthy behaviors in different groups. However, a questionnaire has not yet been developed to evaluate the health behaviors that medical practitioners often consider in individuals with cancer or at a high risk of developing cancer.
Purpose:
The aim of this study was to construct and validate the Health Behavior and Stages of Change Questionnaire (HBSCQ), which is based on the TTM and health recommendations related to risk and factors that protect against cancer.
Methods:
Content validity was conducted in two phases (qualitative and quantitative). Item difficulty index, item discrimination index, and discrimination coefficient were obtained based on the classical test theory. Finally, Cronbach's alpha was used.
Results:
Measure of concordance showed scores considered adequate and excellent. The item discrimination index obtained a rating of "excellent" and suggested the preservation of all items. The discrimination coefficient scores are >0.74. The global internal consistency of the HBSCQ was 0.384. HBSCQ specification between groups of internal consistency for the sample of men was 0.712 and that for the sample of women was 0.378.
Conclusion/Implications For Practice:
The HBSCQ represents a proposal for a fast, simple, and innovative screening test, which aims to identify persons who may benefit from interventions to promote health behaviors delimited to the stage of change.
