The effects of exposure to televised thin and average size models on body dissatisfaction and actual food intake were examined. Normal weight female students (N=104) were exposed to a 30-min movie clip featuring beautiful girls. Half of them viewed the movie clip in normal screen size (4:3) and the other half viewed the same movie clip in broad screen size (16:9), in which the body size of the actresses was slightly stretched breadthways. Actual food intake while watching and body dissatisfaction afterwards was examined. Additionally, restrained eating was assessed as a possible moderating variable. Two interaction effects were found between screen size and restrained eating on body dissatisfaction and actual food intake. Restrained eaters tended to feel worse and eat less in the average size condition compared to the thin model condition, whereas unrestrained eaters felt worse and ate less in the thin model condition compared to the average size condition. So, body size of televised images affected body dissatisfaction and food intake, differentially for restrained and unrestrained eaters. The screen sizes used correspond with widely used screen sizes nowadays enhancing the practical relevance of the study, since screen size might affect body dissatisfaction and food intake in daily life as well.
研究了观看电视中身材瘦和身材中等的模特对身体不满和实际食物摄入量的影响。正常体重的女学生(N = 104)观看了一段30分钟的电影片段,内容是漂亮女孩。其中一半学生以正常屏幕尺寸(4:3)观看该电影片段,另一半学生以宽屏尺寸(16:9)观看相同的电影片段,在宽屏尺寸下女演员的身材在横向略有拉长。研究了观看时的实际食物摄入量以及之后的身体不满情况。此外,将节食作为一个可能的调节变量进行了评估。在屏幕尺寸和节食对身体不满和实际食物摄入量方面发现了两个交互作用。与瘦模特条件相比,节食者在中等身材条件下往往感觉更糟且吃得更少,而与中等身材条件相比,非节食者在瘦模特条件下感觉更糟且吃得更少。因此,电视图像中的身材对身体不满和食物摄入量有影响,对节食者和非节食者的影响有所不同。所使用的屏幕尺寸与当今广泛使用的屏幕尺寸相对应,增强了该研究的实际相关性,因为屏幕尺寸在日常生活中可能也会影响身体不满和食物摄入量。
