Leisure-time sitting-time (LTST) is seen as a possible independent risk-factor for physical and mental health, but research on psychological determinants is sparse. Associations between sitting-time and the personality dimensions of neuroticism, extroversion, openness, agreeableness, and conscientiousness, and the role of general self-efficacy (GSE) were investigated.
A population-based, cross-sectional study was conducted at the Research Centre for Prevention and Health, Denmark, in 2006-08. Men and women (N = 3471) aged 18 to 69, were randomly sampled in the suburbs of Copenhagen. The NEO Five-Factor Inventory, the General Self-Efficacy-Scale, and the Physical Activity Scale 2 were used.
Negative associations were found between LTST and extroversion, conscientiousness, and openness, while neuroticism showed a positive association (R2 = .13). The associations with agreeableness became significantly positive, when GSE was included. All 5 associations were mediated by GSE, with mediation proportions between 23%-60%; but with modest effect sizes.
These cross-sectional results indicate that personality traits and GSE could be considered as associates of LTST; but future longitudinal data are necessary to make causal statements and rule out alternative models fitting data.
休闲时间久坐被视为身心健康的一个潜在独立风险因素，但关于其心理决定因素的研究还很匮乏。本研究旨在探讨久坐时间与神经质、外向性、开放性、宜人性和尽责性等人格维度之间的关系，并分析一般自我效能感（GSE）的作用。
该研究为基于人群的横断面研究，于 2006-2008 年在丹麦预防与健康研究中心进行。哥本哈根郊区随机抽取了 18 至 69 岁的男性和女性（N=3471）。采用 NEO 五因素人格量表、一般自我效能感量表和体力活动量表 2 进行评估。
久坐时间与外向性、尽责性和开放性呈负相关，而与神经质呈正相关（R2=0.13）。当纳入一般自我效能感后，宜人性与久坐时间的相关性变为显著正相关。所有 5 种相关性均通过一般自我效能感起中介作用，中介比例在 23%-60%之间，但效应量较小。
这些横断面研究结果表明，人格特质和一般自我效能感可以被视为久坐时间的相关因素；但需要进一步的纵向研究来做出因果关系的结论，并排除拟合数据的替代模型。
