OBJECTIVES
The aim of the current study is to develop a valid and reliable instrument with psychometric qualities to measure effect of social media usage on eating behaviour in university students.
DESIGN
A thirty-eight-item draft scale developed by the researchers. After content validity, twenty-two items are remained and was used to collect the data. In the analysis of the data, confirmatory factor analyses were performed to test construct validity. For the reliability of the scale, Cronbach alpha coefficient was calculated for the whole of the scale.
SETTING
The participants attended from various departments of different universities in Ankara.
PARTICIPANTS
The scale was administered to the study group consisting of 247 university students.
RESULTS
Four items that had total correlation value less than 0·40 were removed from scale. The reliability coefficient of the whole eighteen-item scale was found to be 0·928.
CONCLUSIONS
It has been shown that the scale developed as a result of the validity and reliability analyses performed for the scale is a valid and reliable measurement tool and can be used in studies.
目的
本研究旨在开发一种具有心理测量学特性的有效且可靠的工具，以衡量社交媒体使用对大学生饮食行为的影响。
设计
由研究人员制定的 38 项草案量表。经过内容有效性验证后，保留了 22 项，并用于收集数据。在数据分析中，进行了验证性因子分析以检验结构有效性。为了评估量表的可靠性，计算了整个量表的克朗巴赫α系数。
设置
参与者来自安卡拉不同大学的不同系。
参与者
该量表施用于由 247 名大学生组成的研究组。
结果
从量表中删除了总相关值小于 0.40 的四项。整个 18 项量表的可靠性系数为 0.928。
结论
经过对量表进行的有效性和可靠性分析，结果表明所开发的量表是一种有效且可靠的测量工具，可用于研究。
