“…The current findings are also consistent with previous studies among people with type 2 diabetes that have identified positive correlations with conscientiousness [5]. Positive relationships between conscientiousness and physical activity are also common in the general and obesity populations [14,15,17]. The tendency toward higher levels of self-discipline and dutifulness that conscientious people embody may be responsible for self-regulating behaviour such as physical activity [5,17,18].…”

“…For example, in this study, physical activity had the strongest positive correlation with extraversion, followed by openness and conscientiousness (both positive), among adults with type 2 diabetes. These findings are collectively consistent with those of large meta-analyses based on the general and obesity populations [14,15,17]. However, in previous type 2 diabetes studies in which the Big Five had been assessed, extraversion had not correlated with physical activity or other weight management indicators [5].…”

“…Within the obesity population and among people with cardiovascular disease, effective weight management is generally related to higher conscientiousness and lower neuroticism and, less consistently, with extraversion [12][13][14][15]. Yet, comparatively fewer studies have specifically examined the personality-weight management relationship in type 2 diabetes.…”

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 R2 = .31, R2 difference = .03, p = .03; openness: β = .16, p = .02, emotionality: β = .15, p = .04) and healthy diet (Adjusted R2 = .19, R2 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.
