TL;DR

In a cross-sectional survey of 270 Australian adults with type 2 diabetes, all six HEXACO personality domains showed significant bivariate correlations with at least one weight management indicator, but personality explained only small additional variance in physical activity and healthy diet beyond demographic, clinical, and psychosocial covariates, and no additional variance in BMI.

This cross-sectional study recruited 270 Australian adults with type 2 diabetes via the national diabetes registry. Participants completed an online survey measuring HEXACO-PI-R personality domains, weight management indicators (physical activity via IPAQ-SF, healthy diet via UKDDQ, and BMI), general well-being (WHO-5), general self-efficacy (GSE), diabetes distress (DDS), and diabetes self-efficacy (DMSES). The findings suggest personality may have unique but small value in understanding weight management in type 2 diabetes.

ABSTRACT

The objective of this study was to examine the associations between personality, general and diabetes-specific well-being and self-efficacy, and weight management indicators, among adults with type 2 diabetes. In addition, to examine whether personality provides incremental explanation of variance in weight management indicators. Australian adults with type 2 diabetes (N = 270; 56% women; age: 61±12 years) were recruited via the national diabetes registry. An online survey included measures of: personality (HEXACO-PI-R), weight management indicators (physical activity, healthy diet, body mass index [BMI]), general well-being (WHO-5), general self-efficacy (GSE), diabetes distress (DDS) and diabetes self-efficacy (DMSES). Analyses included bivariate correlations and linear regression, adjusted for demographic, clinical, and psychological variables. All six personality domains showed significant correlation with at least one weight management indicator: physical activity with extraversion ( r = .28), conscientiousness ( r = .18) and openness ( r = .19); healthy diet with honesty-humility ( r = .19), extraversion ( r = .24), and agreeableness ( r = .14); and BMI with emotionality ( r = .20) and extraversion ( r = -.20). The strongest associations with general and diabetes-specific well-being and self-efficacy were apparent for extraversion, emotionality and conscientiousness (range: r = -.47-.66). Beyond covariates, personality domains explained additional variance for physical activity (Adjusted R 2 = .31, R 2 difference = .03, p = .03; openness: β = .16, p = .02, emotionality: β = .15, p = .04) and healthy diet (Adjusted R 2 = .19, R 2 difference = .03, p = .02; honesty-humility: β = .20, p = .002, extraversion: β = .19, p = .04) but not BMI. This study shows that personality is associated with weight management indicators and psychological factors among adults with type 2 diabetes. Further research is needed, including objective measurement of weight management indictors, to examine how personality influences the experience of type 2 diabetes.
