Background: Most of the individuals concerned by colorectal cancer screening recognize the importance of screening participation. However, the screening rates for this cancer remain low in most countries, including France. Based on the action control framework, the present study aimed to (i) explore the distribution of intentions-behavior profiles toward colorectal cancer screening and (ii) to determine to what extent the profiles could be differentiated on theory of planned behavior (TPB) (i.e., attitudes, subjective norms, perceived behavioral control [PBC]) and self-regulation variables (i.e., action planning, coping planning).
Method: A total of 149 participants from the general French population (M = 60 years, SD = 7.04) completed a questionnaire measuring TPB and self-regulation variables. Subsequent screening behavior was determined from medical records. Participants were notably categorized as non-intenders, unsuccessful intenders, or successful intenders. Data were analyzed using discriminant function analysis and analyses of covariance.
Results: Main findings revealed that 71% of the intenders were unsuccessful intenders. TPB and self-regulation variables were significantly correlated with the discriminant function (rs ≥ .40). Successful and unsuccessful intenders reported significantly higher levels of subjective norms, PBC, and coping planning than non-intenders (ps < .01). Successful intenders reported a significantly higher level of coping planning than unsuccessful intenders (p < .01).
Conclusions: Further research appears necessary to empirically test to what extent interventions targeting subjective norms, PBC, and coping planning could enhance the proportion of successful intenders toward colorectal cancer screening.
