Enjoyment and play during school lunchtime are correlated with children's physical activity. Despite this, there is an absence of studies reporting children's enjoyment of play during school lunchtime breaks. The purpose of this study was to examine the intraday and interday reliability of children's enjoyment of school lunchtime play.
Surveys used to assess children's enjoyment of lunchtime play were distributed to and completed by 197 children (112 males, 85 females), aged 8-12 years attending an elementary school in Victoria, Australia. Children completed the surveys during class before lunch (expected enjoyment) and after lunch (actual enjoyment) for 5 days. The intra- and interday enjoyment of school lunchtime play reliability were determined using a weighted kappa.
Intraday kappa values ranged from fair (0.31) to substantial (0.75) within each of the 5 days (median kappa = 0.41). In comparison, "expected" (0.09-0.40; median 0.30) and "actual" (0.05-0.46; median 0.28) interday enjoyment of lunchtime play displayed low reliability.
Children's enjoyment of lunchtime play appears to be more consistent within days than across days. The findings suggest that assessment of children's enjoyment of lunchtime play once on a single day would be representative of a particular day but not necessarily that particular school week.
学校午餐时间的乐趣和玩耍与儿童的身体活动相关。尽管如此，尚无研究报告儿童在学校午餐休息时间玩耍的乐趣。本研究的目的是检验儿童对学校午餐时间玩耍乐趣的日内和日间可靠性。
用于评估儿童午餐时间玩耍乐趣的调查问卷分发给澳大利亚维多利亚州一所小学的197名8至12岁儿童（112名男性，85名女性）并由他们完成。儿童在午餐前上课期间（预期乐趣）和午餐后（实际乐趣）连续5天完成调查问卷。使用加权kappa系数确定学校午餐时间玩耍乐趣的日内和日间可靠性。
在5天中的每一天，日内kappa值范围从一般（0.31）到较高（0.75）（kappa中位数 = 0.41）。相比之下，午餐时间玩耍的“预期”（0.09 - 0.40；中位数0.30）和“实际”（0.05 - 0.46；中位数0.28）日间乐趣显示出低可靠性。
儿童对午餐时间玩耍的乐趣在日内似乎比日间更具一致性。研究结果表明，在某一天对儿童午餐时间玩耍乐趣进行一次评估将代表特定的一天，但不一定代表特定的学校周。
