Background: Value-based care (VBC) entails improving the quality and value of healthcare for patients by focusing on costs, quality of healthcare services, and quality of life, holistically. The theory of planned behaviour (TPB) is a psychological model outlining individuals’ intentions and behaviours towards VBC to understand how individuals engage in a specific behaviour. Thus, we developed a questionnaire based on VBC and TPB to collect data from sixth-year medical students and postgraduate trainees to identify and compare factors affecting the intention and application of the VBC principle in patient care between these two groups.
Methods: Cross-sectional study (December 2022January 2023) data were collected and analysed using descriptive statistics for personal factors; Spearman rank correlation statistics explored the relationship based on TPB between the score of attitudes towards behaviour, subjective norms, perception of behavioural control, intention to perform behaviour, and application of principles; and a multiple regression analysis was conducted to examine the predictive factors among variables.
Results: This study involved 90 participants, 51 (56.67%) postgraduate trainees and 39 (43.33%) undergraduate students. Spearman rank correlation found relationships between each part of TPB, showing a significant difference in behaviour scores between the two groups. In the multiple regression analysis, attitude and perception scores were positive predictors of intention scores, while postgraduate status, perception scores, and perception of family socio-economic status were significant, positive predictors of behaviour scores. A subgroup analysis revealed that perception scores were positive predictors of both intention and behaviour scores for both groups. Furthermore, being a sixth-year student with a family member suffering from a chronic illness was positively associated with higher behaviour scores (β= 6.28, p-value 0.003). In the postgraduate group, attitude scores and perception of family socio-economic status were correlated with intention scores (β= 0.36, p-value 0.018) and behaviour scores (β=4.14, p-value 0.002).
Conclusions: TPB is a suitable theoretical basis for examining factors influencing the adoption of VBC. Additionally, the perception of behavioural control significantly affects the intention to perform behaviour related to the application of principles in patient care among sixth-year medical students and postgraduate trainees.
