Aspect was form of exposure, and within-group element, pre- to post-exposure. The dependent variables PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21300754 have been appearance comparison (AC) and physique image dissatisfaction transform (BID-change) calculated by subtractingCohen and Blaszczynski Journal of Eating Issues (2015) 3:Page 3 ofpre-exposure from post-exposure BID. Covariates had been baseline thin-ideal internalisation, self-esteem and BMI.distractors. Only participants who selected the correct two pictures were incorporated in the analyses.Measures DemographicsMaterialsExperimental stimuli Facebook stimuliFacebook stimuli consisted of ten slides depicting five mock profile-pages. The profiles were developed to reflect the realistic expertise of viewing actual Facebook profiles. There were two slides per profile: thin-ideal profile-pictures (depicting thin females, comparable to these in the traditional media pictures), status’, peer comments, `tagged’ images and adverts in the side-bar, and; a `zoomed-in’ profile or tagged image inclusive of friends’ comments as displayed when clicking around the picture. The presentation of Facebook stimuli within this way was CFMTI web intended to simulate a additional realistic expertise of Facebook, and to reflect the interactive nature of SNSs in comparison to conventional media photos. Stimuli had been chosen based on the ratings of a convenience sample of ten independent female university students. As a way to ensure that the images have been reflective of both appealing and thin images, raters viewed a series of 20 Facebook photos and indicated the extent to which these had been attractive and reflecting a thin-ideal making use of a 5-point Likert scale ranging from 1 (not at all) to five (to an extreme extent). Ten photos receiving the highest scores (M = 4.1, SD = 1.12) had been chosen for use. To boost the external validity from the study, peer comments had been derived from those located on real Facebook profile-pages, and participants had been capable to access stimuli from house computers in lieu of a laboratory internet site. The photos and comments connected for the beach, exercising, glamour andor diet program. (Note. all Facebook names had been fabricated and photographs were obtained by way of public access to Facebook).Conventional media stimuliParticipants self reported age, weight, height, best weight and raceethnicity. Self-reported height and weight have been applied to calculate BMI (weight in kilograms divided by the square on the height in metres).Facebook useParticipants self reported the extent and type of their Facebook use such as number of years spent applying, hours each day, occasions per day and days per week. Extent of Facebook use scores had been calculated by hours per access x access each day x days accessed per week.Form of Facebook useParticipants were asked how typically they engaged in several Facebook activities for example looking at profiles of other folks and reading comments posted by others on a 5-point Likert scale ranging from 1 (by no means) to five (often). This metric was applied to test the external validity in the stimuli by comparing the extent of similarity among actual Facebook use with experimental stimuli. For this study, the scale showed good reliability (Cronbach’s alpha = .828).Thin-ideal internalisationConventional print media stimuli consisted of ten thin-ideal industrial photos of modelscelebrities with themes matched to these inside the Facebook profiles (i.e., beach, exercising, glamour andor diet plan). The photos consisted of magazine covers or advertisements found in popular magazines and presented in their original format. Exactly the same sel.
