Associations across self-efficacy, social support, and multiple measures of physical activity (PA) have not been thoroughly explored in hospital employees.
Validated surveys assessed psychosocial factors; the IPAQ-long assessed PA, and mixed-effects analyses examined relations between psychosocial variables and PA in 920 employees from 6 Texas hospitals.
At P <.05, self-efficacy was significantly associated with light (β = 1.67), moderate (β = 1.63), and vigorous (β = 2.78) leisure PA; with domestic PA (β = 1.64); and with moderate commute PA (β = 0.03). At P < .05, family social-support was significantly associated with light (β = 0.94), moderate (β = 0.63), and vigorous (β = .74) leisure PA; with moderate (β = 0.46) and vigorous (β = 1.24) occupation PA; with light (β = 0.58) and moderate (β = 0.20) commute PA; and with domestic PA (β = 1.18). At P < .05, social support from friends was significantly associated with light (β = 0.74), moderate (β = 0.58), and vigorous (β = .91) leisure PA; with moderate commute (β = 0.21); and with domestic PA (β = 0.82).
Interventions must emphasize self-efficacy-building strategies and the role of family support to meaningfully impact PA behaviors in this unique population.
自我效能感、社会支持与多种体力活动（PA）测量指标之间的关联在医院员工中尚未得到充分探讨。
使用经过验证的调查评估心理社会因素；使用 IPAQ-long 评估 PA，并在来自德克萨斯州 6 家医院的 920 名员工中使用混合效应分析检查心理社会变量与 PA 之间的关系。
P<.05 时，自我效能感与轻（β=1.67）、中（β=1.63）和剧烈（β=2.78）休闲 PA；与家务 PA（β=1.64）；以及与中强度通勤 PA（β=0.03）显著相关。P<.05 时，家庭社会支持与轻（β=0.94）、中（β=0.63）和剧烈（β=0.74）休闲 PA；与中（β=0.46）和剧烈（β=1.24）职业 PA；与轻（β=0.58）和中（β=0.20）通勤 PA；以及家务 PA（β=1.18）显著相关。P<.05 时，来自朋友的社会支持与轻（β=0.74）、中（β=0.58）和剧烈（β=0.91）休闲 PA；与中强度通勤（β=0.21）；以及家务 PA（β=0.82）显著相关。
干预措施必须强调自我效能建设策略和家庭支持的作用，以对这一独特人群的 PA 行为产生有意义的影响。
