ABSTRACT

To validate the modified System for Observing Fitness Instruction Time to measure teacher practices related to physical activity promotion (SOFIT+) in physical education (PE) amongst 5–6-year-old-children. Participants (n = 162, 53% female, 6.0 ± 0.3 yrs) were recruited from 9 schools. Video-recordings of 45 PE lessons from 9 teachers/coaches were coded using a modified SOFIT+. Accelerometers measured children’s moderate-to-vigorous physical activity (MVPA). Validity was assessed via multinomial regression measuring the relationship of both SOFIT+ index score and individual teaching practices with children’s MVPA. Inter-rater reliability was examined. A 1 unit increase in the SOFIT+ index was associated with increased likelihood to engage in 10–19 sec, 20–29 sec and 30–40 sec of MVPA, compared to 0–10 sec. Most of the observed teaching practices were significantly related to children’s MVPA. Inter-rater percentage of agreement ranged between 88.8% and 99.7%. SOFIT+ is a valid and reliable assessment of teaching practices related to MVPA promotion in PE amongst 5–6-year-old-children.

摘要

验证修改后的健身指导时间观察系统，以衡量教师在 5-6 岁儿童体育教育 (PE) 中促进体育活动 (SOFIT+) 的实践。参与者 ( n= 162, 53% 女性, 6.0 ± 0.3 岁) 从 9 所学校招募。来自 9 位教师/教练的 45 节体育课的录像使用修改后的 SOFIT+ 编码。加速度计测量儿童的中度到剧烈的体力活动 (MVPA)。有效性是通过多项回归评估 SOFIT+ 指数分数和个人教学实践与儿童 MVPA 的关系。检查了评价者间的可靠性。与 0-10 秒相比，SOFIT+ 指数增加 1 个单位与参与 10-19 秒、20-29 秒和 30-40 秒 MVPA 的可能性增加有关。大多数观察到的教学实践与儿童的MVPA显着相关。评估者间的一致性百分比介于 88.8% 和 99.7% 之间。
