Sedentary behavior (SB) is an important public health concern. Adults working in desk-based occupations spend a considerable proportion of the workday sitting. More information is needed regarding the factors that contribute to occupational SB. The aim of this study was to assess the utility of social cognitive theory (SCT) to explain work-related SB using a quantitative, cross-sectional design by administering an online questionnaire. Participants included 381 full-time employees at a large, public university in the south-central United States. Hierarchical multiple linear regression was used to determine the relationship between SCT constructs and SB. Mean work-related SB was 5.95 (SD = 1.30) h/8 h workday. In model 1, 9.6% of the total variance in SB was accounted for by standing desk ownership and physical activity level ( = 0.001; R2 = 0.096). In model 2, SCT constructs led to a statistically significant R increase of 4.9% ( < 0.001), where standing desk ownership, physical activity, and self-efficacy explained 13.3% of the variance in work-related SB. Findings from this study suggest that self-efficacy may be an important factor in explaining variation in occupational SB. Public health researchers and practitioners should consider strategies to address self-efficacy when developing workplace interventions to target occupational SB.
久坐行为（SB）是一个重要的公共卫生关注点。从事基于办公桌的职业的成年人在工作日中有相当一部分时间是坐着的。需要更多关于导致职业 SB 的因素的信息。本研究旨在通过使用在线问卷进行定量、横断面设计，评估社会认知理论（SCT）在解释与工作相关的 SB 方面的效用。参与者包括美国中南部一所大型公立大学的 381 名全职员工。分层多元线性回归用于确定 SCT 结构与 SB 之间的关系。平均与工作相关的 SB 为 5.95（SD=1.30）h/8 h 工作日。在模型 1 中，站立式办公桌拥有率和身体活动水平解释了 SB 总方差的 9.6%（=0.001；R2=0.096）。在模型 2 中，SCT 结构导致统计学上显著的 R 增加 4.9%（<0.001），其中站立式办公桌拥有率、身体活动和自我效能感解释了与工作相关的 SB 变异的 13.3%。本研究的结果表明，自我效能感可能是解释职业 SB 变异的一个重要因素。公共卫生研究人员和从业者在制定针对职业 SB 的工作场所干预措施时，应考虑针对自我效能感的策略。
