Brief Summary

The effect of emotional induction of sadness (vs. joy) on the mental representation of the body image through the virtual reality

Detailed Description

The general objective of this study is to analyze the impact of emotional induction (sadness vs. joy) on the two dimensions (perceptive and affective) of body image with the help of virtual reality. Thus, it is hypothesized that a negative emotional induction may partially explain the change in body image measures.

Primary Outcome Measures

Name	Time	Method
Change in the Body image estimation	Baseline; inmediately after procedure	Software Cognitive (developed at the lab) measuring real and ideal body size estimation based on Glendhill et al. (2017) and using Virtual Reality. The results will be reflected as Body Mass Index change (estimation of the own body size and the ideal body size in BMI).; In the present study, a total of 31 female avatars with different BMI were developed.; The VR evaluation program allowed for tasks to be performed to estimate the body size (for one's own body and for the ideal body). The body size estimation tasks consisted of two phases. In the first phase, 8 avatars with a different BMI ranging from 14.5 to 28.5 were presented randomly. Ten repetitions were performed for each avatar. In the second phase, 5 avatars were shown with a BMI greater and less in 2 units to the cut-off point estimated in the first phase of the estimation task. Five repetitions were performed for each avatar.
Change in the Body image dissatisfaction state	Baseline; inmediately after procedure	Body Image States Scale (BISS; Cash, Fleming, Alindogan, Steadman y Whitehead, 2002).; This is a 6-item self-report questionnaire that measures the individuals' evaluation and affect about their physical appearance (e.g., body image appraisal and satisfaction, as well as emotional experiences) at a particular moment in time: (1) satisfaction with one's overall physical appearance, (2) satisfaction with one's body size and shape, (3) satisfaction with one's weight; (4) feelings of physical attractiveness; (5) current feelings about one's looks relative to how one usually feels; and (6) evaluation of one's appearance relative to how the average person looks. Items are rated on a 9-point bipolar Likert scale. The measure is the composite mean of the items, and higher scores reflect a more favorable body image satisfaction state. The BISS was acceptably internally consistent in the original validation. A Spanish version was translated by the authors of the study.

Secondary Outcome Measures

Name	Time	Method
Change in the Positive and negative affect	Baseline; inmediately after procedure	(PANAS; Watson, Clark, and Tellegen, 1988; Spanish adaptation by López-Gómez, Hervás y Vázquez, 2015).The instrument consists of two scales: positive affection scale (PA) and negative affection scale (NA), each consisting of 10 items. The items are scored using a five-point Likert scale (1 = not at all or very slightly to 5 = very much) in the specified time period (in this study: "right now"). The total score corresponding to the presence of a specific affection, between 10 and 50, is obtained with the sum of the scores of each of the items on the scale. In the Spanish adaptation of the instrument, by López-Gómez, Hervás and Vázquez (2015), the Cronbach alpha coefficient was .92 for the PA and .88 for the AN. While the item-total correlations of the AP factor oscillate between .67 and .74, while those of the AN factor oscillate between .52 and .69.
