Body Image and Sexual Dissatisfaction: Differences Among Heterosexual, Bisexual, and Lesbian Women.

Gender-based differences in body image dissatisfaction are not conclusive. Women's body experiences and their impact on sexual satisfaction may advance knowledge on how heterosexual, bisexual, and lesbian women internalize heterosexist values. In this study, we quantitatively examined the degree of body image and sexual dissatisfaction experienced by heterosexual, bisexual, and lesbian women, to determine whether body dissatisfaction can predict sexual dissatisfaction. Three hundred and fifty-four women completed an online survey measuring body and sexual dissatisfaction. No sexual orientation-based differences were observed in body or sexual dissatisfaction; however, body concerns were found to have less influence on sexual dissatisfaction in lesbian women compared to heterosexual and bisexual women. Standards of beauty remain constant among all women, yet removing themselves from the male gaze may be interpreted as a protective factor which shields women from expressing concern about their appearance during sexual activity.

Body Mass Index and Nationality (Argentine vs. Spanish) Moderate the Relationship Between Internalization of the Thin Ideal and Body Dissatisfaction: A Conditional Mediation Model.

It is believed that Women's exposure to Western sociocultural pressures to attain a "thin-ideal" results in the internalization of a desire to be thin that consequently leads to body dissatisfaction (BD). It is also well documented that body mass index (BMI; kg/m2) correlates with BD. We tested for the first time a conditional mediation model where thin-ideal Awareness predicted BD through Internalization of the thin ideal and the path from Internalization to BD was hypothesized to be moderated by BMI and Nationality (Argentine vs. Spanish). The model was tested with a sample of 499 young women (age = 18 to 29) from Argentina (n = 290) and Spain (n = 209). Awareness and internalization were measured with the SATAQ-4 (Schaefer et al., 2015) and BD was measured with the BSQ (Cooper et al., 1987). The model was analyzed using PROCESS v3.1 (Hayes, 2018). As hypothesized, thin-ideal awareness predicted BD through internalization and the path from internalization to BD was moderated by BMI and nationality. Specifically, internalization predicted BD at all level of BMI and in both samples, but the relationship between internalization and BD increased with BMI and was also stronger among Spaniards than Argentines. We argue that the findings are congruent with theories that predict that economic development and modernization contribute to normative female BD through internalization of the thin ideal and that upward social comparisons or cognitive discrepancy between self-perceived body image and the sociocultural thin ideal interacts synergistically with thin-ideal internalization to increase BD.

Body dissatisfaction and mirror exposure: evidence for a dissociation between self-report and physiological responses in highly body-dissatisfied women.

BACKGROUND: Weight and shape concerns are widespread in the general population. Mirror exposure has been used to reduce body dissatisfaction but little is known about the mechanisms which underlie this therapeutic technique. The present study examined emotional, cognitive, and psychophysiological responses, in women with high and low levels of body dissatisfaction, exposed to their own bodies in a mirror. METHOD: Forty-two university-attending women (21 high body-dissatisfied (HBD) and 21 low body-dissatisfied (LBD)), were confronted with their own body during four 5-min trials in which participants were instructed to focus their attention on different parts of their body under standardized conditions. Emotional and cognitive measures were taken after each exposure trial. Heart rate (HR) and skin conductance (SC) were recorded continuously. RESULTS: HBD women experienced more negative emotions and cognitions following body exposure compared to LBD women but, conversely, showed a reduced physiological reaction in terms of HR and SC. In both groups greater physiological responses were observed looking at the thighs, buttocks, and abdomen. Extent of negative emotions and cognitions were positively associated with HR and/or SC in LBD women but no associations were observed in HBD women. CONCLUSION: The dissociation between self-report and psychophysiological measures in HBD women supports the existence of a passive-behavioral inhibited coping style in HBD women and suggests deficiencies in the generation of physiological correlates of emotion related to body dissatisfaction.

Testing the efficacy of pure versus guided mirror exposure in women with bulimia nervosa: A combination of neuroendocrine and psychological indices.

BACKGROUND AND OBJECTIVES: Body exposure improves body image problems in women with eating disorders. However it has almost always been combined with other interventions. Thus, the efficacy of body exposure alone (i.e., pure exposure) remains largely unclear. We aimed to compare the efficacy of two body exposure techniques through psychological and neuroendocrine indices recorded within and between successive sessions. METHOD: Twenty-nine women with high body dissatisfaction and diagnosis of bulimia nervosa were randomly assigned to one of two treatment groups: Pure Exposure (n = 14) or Guided Exposure (n = 15). Participants received 6 exposure sessions. After each session, changes in thoughts (positive/negative) and body satisfaction were assessed. Also, we assessed the body discomfort experienced by participants within and between sessions. Finally, the changes in salivary cortisol levels within and between the initial and final treatment sessions were measured. RESULTS: Both groups showed a reduction in negative thoughts and a progressive increase in positive thoughts throughout the treatment. However, the increase in body satisfaction and the reduction in subjective discomfort within the sessions were greater in the pure exposure group. The cortisol levels during the initial and final treatment sessions decreased in both groups. LIMITATIONS: Methodological limitations are reported. CONCLUSIONS: These results suggest that pure and guided exposures are effective interventions for improving thoughts and neuroendocrine responses, although pure exposure increased more body satisfaction feelings in bulimic women. Subjective discomfort also showed different patterns of change within and along sessions for each treatment. Reasons for these results are discussed.

Impact of fasting on food craving, mood and consumption in bulimia nervosa and healthy women participants.

Researchers have found that dietary restraint increases food cravings and may contribute to loss of control over eating. Negative mood states often precede food cravings and binge eating. In the present study, we tested the influence of a prolonged food deprivation period over emotional states and food cravings. Twenty-one bulimia nervosa participants and 20 healthy women participants were asked to refrain from any eating for 20 hours and reported, at baseline, after 6 hours and at the end of the fasting period, their mood and craving states. Food consumption was also measured. Fasting increased food cravings in both groups but increased negative mood in healthy women only. Bulimia nervosa participants reported improved mood following food deprivation. Whereas Bulimia nervosa and healthy women participants ate moderate and similar amounts of food following the 20-hour fasting period, food cravings were significantly associated with the number of calories ingested. These findings are congruent with self-regulation theories that predict that prolonged fasting may reduce negative emotions in women with bulimia nervosa.

Pure versus guided mirror exposure to reduce body dissatisfaction: a preliminary study with university women.

While effectiveness of mirror exposure to reduce body dissatisfaction has been demonstrated, the exposure was almost always combined with other interventions. The aim of the study was to evaluate the effectiveness of a pure mirror exposure intervention compared with a guided mirror exposure (participants are guided to describe their body shape in a non-evaluative manner) and an imagery exposure intervention (participants are guided to describe their body through mental representation). Thirty-one women with high body dissatisfaction received five sessions of treatment under one of the three conditions. All interventions reduced body dissatisfaction, but only the mirror exposures successfully reduced the frequency of negative thoughts and feelings of ugliness. Pure mirror exposure was more effective than guided exposure for reducing body discomfort within and between sessions. Pure mirror exposure, based on the traditional extinction paradigm, led to strong emotional activation followed by a fast decrease in emotional reactivity.

Experimental effects of chocolate deprivation on cravings, mood, and consumption in high and low chocolate-cravers.

This study examined how deprivation of chocolate affects state-level chocolate cravings, mood, and chocolate consumption in high and low trait-level chocolate-cravers. After identifying high and low chocolate cravers (N=58), half of the participants were instructed not to eat any chocolate for 2weeks. This created four experimental groups: deprived high-cravers (n=14), deprived low-cravers (n=14), non-deprived high-cravers (n=15), and non-deprived low-cravers (n=15). Following 2-week deprivation, state-level food cravings, mood, and chocolate intake were measured in a laboratory setting and compared across groups. Analyses revealed that anxiety increased over time for high-cravers (both deprived and non-deprived); state-level chocolate- and food-craving increased over time for both deprived groups and non-deprived high-cravers; non-deprived high-cravers ate the most chocolate; and, high-cravers were more joyful and guilty than low-cravers after eating chocolate in the laboratory. Theoretically, these results suggest that chocolate consumption may be better explained by trait-level of chocolate craving than by deprivation and highlighted significant differences in mood, state-level cravings, and chocolate intake between cravers and non-cravers following deprivation.
