Effect of Thin vs. Plus-Size Models: A Comparison of Body Image Ideals by Gender
Unformatted Document Text:  Ideal Body Image, 24 the average woman. In terms of attractiveness, no significant differences were observed among women, although men found thin models to be more attractive than the plus-size models. Effects of Experimental Factor Actual Body Shape. The effect of model-type was evaluated using a 2 (Model Type: thin, plus-size) x 2 (pre, post) mixed design, where type of model was a between- subjects factor and the pre- and post-assessment of body shape was a within-subject factor. As in Experiment 1, self-esteem, physique anxiety, and body mass index were entered as covariates. Because the dependent variable here is actual body shape, the sample was reduced to only female participants. Summary of means is presented in Table 3. Main effects for model type, F (1, 120) = 4.53, p < .05, MSe = 0.92, physique anxiety, F (1, 120) = 11.74, p < .001, MSe = 0.92, and body mass index, F (1, 120) = 189.55, p < .05, MSe = 0.92, were significant. Also, the Pre-Post x Model, F (1, 120) = 6.54, p < .05, MSe = 0.26, interaction was significant. None of the other main effects or interactions were significant. Given the close ties among body mass, physique anxiety, and the dependent variable, body shape, the main effects for body mass and physique anxiety are not surprising. The main finding was the interaction between model-type and the shift in the pre- post evaluation, which supports H6. Among women in the thin models condition, the shift from pre (M = 3.5) to post (M = 3.6) was not significant. However, among women in the plus-models condition, there was a significant shift in actual body shape from the pre (M = 3.5) to the post (M = 3.8) evaluation, t (58) = 2.80, p < .01.

Actual Body Shape. The effect of model-type was evaluated using a 2 (Model
Type: thin, plus-size) x 2 (pre, post) mixed design, where type of model was a between-

189.55, p < .05, MSe = 0.92, were significant. Also, the Pre-Post x Model, F (1, 120) =
