To determine the acceptability, internal consistency and test-retest reliability of self-efficacy, motivation and knowledge scales relating to pre-school children's nutrition, oral health and physical activity.
An online questionnaire was completed twice with an interval of 7-11d.
Online questionnaires were sent to participants via email from nursery managers. The parent questionnaire was also available on the parenting website www.netmums.com.ParticipantsEighty-two parents and sixty-nine nursery staff from Bristol, UK who had and worked with 2-4-year-olds, respectively.
Response rates were 86·3 and 86·0 % and missing data 15·9 and 14·5 % for the second administration of the parent and nursery staff questionnaires, respectively. Weighted κ coefficients for individual items mostly fell under the 'moderate' agreement category for the parental (75·0 %) and nursery staff (55·8 %) items. All self-efficacy and motivation scales had acceptable levels of internal consistency (Cronbach's α coefficients>0·7). The intraclass correlation coefficients for the self-efficacy, motivation and knowledge scales ranged between 0·48 and 0·82. Paired t tests found an increase between test and retest knowledge scores for the Nutrition Motivation (t=-2·91, df=81, P=0·00) and Knowledge (t=-3·22, df=81, P=0·00) scales in the parent questionnaire.
Our findings demonstrate that the items and scales show good acceptability, internal consistency and test-retest reliability.
确定与学龄前儿童营养、口腔健康和身体活动相关的自我效能感、动机和知识量表的可接受性、内部一致性和重测信度。
通过电子邮件向托儿所经理发送在线问卷，参与者两次完成在线问卷，两次间隔 7-11 天。
通过电子邮件向参与者发送在线问卷。家长问卷也可在育儿网站 www.netmums.com 上获取。
英国布里斯托尔的 82 名家长和 69 名托儿所工作人员，他们分别与 2-4 岁的儿童有过接触并一起工作过。
第二次家长和托儿所工作人员问卷的应答率分别为 86.3%和 86.0%，数据缺失率分别为 15.9%和 14.5%。对于家长（75.0%）和托儿所工作人员（55.8%）的项目，个别项目的加权κ系数大多属于“中度”一致性类别。所有自我效能感和动机量表的内部一致性水平均较高（Cronbach's α系数>0.7）。自我效能感、动机和知识量表的组内相关系数在 0.48 到 0.82 之间。配对 t 检验发现，家长问卷中营养动机量表（t=-2.91，df=81，P=0.00）和知识量表（t=-3.22，df=81，P=0.00）的测试和重测知识评分之间有增加。
我们的研究结果表明，这些项目和量表具有良好的可接受性、内部一致性和重测信度。
