Purpose: Patients with chronic kidney disease (CKD) are often offered a choice between hemodialysis (HD) and peritoneal dialysis (PD). This study explores the significant factors that affect dialysis modality selection. Based on the theory of planned behavior, we examine whether attitude, subjective norms, and perceived behavioral control predict behavioral intention in patients' dialysis modality choice. Methods: Fifty-seven patients (35 men and 22 women, ages 24-79) with CKD were recruited between July, 2013 to February, 2014. All participants completed 3 questionnaires: The Theory of Planned Behavior Questionnaire, The Kidney Disease Questionnaire, and The Hospital Anxiety and Depression Scale. Results: While controlling for the identified control variables for the outcome, the results of hierarchical regression showed that attitude and perceived behavior control predicted behavioral intention. Conclusions: Understanding CKD patients' attitude and perceived behavior control towards treatment choices is important in the dialysis decision-making process. Theoretical and practical implications are discussed. Reasons that subjective norms did not significantly contribute to behavioral intention were discussed for culture and clinical relevance.
