The effects of physique-salient and physique non-salient exercise videos on women's body image, self-presentational concerns, and exercise motivation

This experiment examined the effects of exposure to physique-salient (PS) and physique non-salient (PNS) exercise videos and the moderating influence of perceived physique discrepancies, on body image, self-presentational concerns, and exercise motivation. Eighty inactive women (M age = 26) exercised to a 30 min instructional exercise video. In the PS condition, the video instructor wore revealing attire that emphasized her thin and toned physique. In the PNS condition, she wore attire that concealed her physique. Participants completed pre- and post-exercise measures of body image, social physique anxiety (SPA) and self-presentational efficacy (SPE) and a post-exercise measure of exercise motivation and perceived discrepancies with the instructor's body. No main or moderated effects emerged for video condition. However, greater perceived negative discrepancies were associated with poorer post-exercise body satisfaction and body evaluations, and higher state SPA. There were no effects on SPE or motivation. Results suggest that exercise videos that elicit perceived negative discrepancies can be detrimental to women's body images.     

Acute effects of exercise on women with pre-existing body image concerns: A test of potential mediators

The primary purpose of this study was to propose and test a mediation model of changes in physical self-efficacy, physical self-perceptions, and affect as mediators by which a single bout of exercise improves state body image. A secondary purpose was to identify how long improvements in state body image are sustained post-exercise. Sixty university-aged women (19.57 ± 1.37 y) with pre-existing body image concerns, and who exercised regularly, were randomized to perform 30 min of moderate-to-vigorous intensity exercise or quiet reading. State body image, physical self-efficacy, physical self-perceptions and affect were assessed. Mediational analyses revealed self-perceptions of body fatness (95% CI [0.03, 0.44], κ² = 0.13, ab_ps = 0.20) and strength (95% CI [0.15, 0.60], κ² = 0.23, ab_ps = 0.33) mediated improvements in state body image which were sustained at least 20 min post-exercise. These results contribute to the development of a model explaining the effects of exercise on body image and practical recommendations for the use of exercise to improve body image.     

The influence of social anxiety on the body checking behaviors of female college students

Social anxiety and eating pathology frequently co-occur. However, there is limited research examining the relationship between anxiety and body checking, aside from one study in which social physique anxiety partially mediated the relationship between body checking cognitions and body checking behavior (Haase, Mountford, & Waller, 2007). In an independent sample of 567 college women, we tested the fit of Haase and colleagues’ foundational model but did not find evidence of mediation. Thus we tested the fit of an expanded path model that included eating pathology and clinical impairment. In the best-fitting path model (CFI = .991; RMSEA = .083) eating pathology and social physique anxiety positively predicted body checking, and body checking positively predicted clinical impairment. Therefore, women who endorse social physique anxiety may be more likely to engage in body checking behaviors and experience impaired psychosocial functioning.     

The effects of leader gender on self-presentational concerns in exercise

The present study examined the impact of the exercise leader's gender on the self-presentational concerns of women in a live exercise class. Eighty-seven college-aged non- or infrequent exercisers participated in a group exercise class led by either a female or male instructor. Participants completed measures of Self-Presentational Efficacy (SPE), State Social Anxiety (SSA) and State Social Physique Anxiety (SPA-S) prior to and following completion of a group exercise class. A repeated measures Multivariate Analysis of Variance (MANOVA), with time as the within-subjects factor and leader gender as the between-subjects factor, was conducted. A significant main effect for time was found (F(3, 80) = 19.65, p < 0.001). Estimated marginal means indicated that all participants reported significantly higher SPE and lower SSA and SPA-S post-exercise. Completing an exercise class may override any self-presentational concerns that can arise from the exercise environment. Future studies should adopt ecologically valid research designs to gain a clearer picture of self-presentational concerns in exercise classes.     

Mediators of affective responses to acute exercise among women with high social physique anxiety

ObjectivesThis study represents ancillary analyses of data published by Raedeke, Focht, and Scales [2007. Social environmental factors and psychological responses to acute exercise for socially physique anxious females. Psychology of Sport and Exercise, 8, 463–487] and examines whether enjoyment or task self-efficacy mediated the relationship between exercise environment (health- or appearance-oriented class atmosphere) and affective responses/future intentions or had independent associations with those outcomes.Design/MethodsAs a context in which to examine mediational relationships, volunteer female college students (N = 99) with high social physique anxiety scores were randomly assigned to a health- or appearance-oriented condition. They completed affect and task self-efficacy measures pre- and post-exercise. Enjoyment and intentions were assessed post-exercise.Results/ConclusionsEnjoyment mediated the relationship of class atmosphere on overall feeling as well as revitalization and exhaustion and partially mediated the relationship of class orientation with engagement and future intentions. Although task self-efficacy was an independent predictor of affective responses and intentions, it did not significantly mediate the effect of the social environment on these outcomes.     

Social cognitive correlates of physical activity among single mothers with young children

ObjectivesSingle mothers experience negative health consequences that might be reduced through participation in physical activity, yet little is known about physical activity correlates among this population. This study examined social cognitive theory (SCT) correlates of physical activity among single mothers with young children.DesignCross-sectional.MethodSingle mothers (N = 94) with at least one child less than 5 years old completed SCT questionnaires, wore an accelerometer for one week, and then completed the Godin Leisure Time Exercise questionnaire. Physical activity scores were standardized and averaged to yield a composite physical activity score.ResultsRegression analysis indicated that self-efficacy was a direct predictor of composite physical activity; in the final model planning was the only statistically significant predictor of composite physical activity scores.ConclusionsPlanning and self-efficacy might be important factors to include when designing physical activity interventions for single mothers.     

The effects of a physical activity and nutrition intervention on body dissatisfaction, drive for thinness, and weight concerns in pre-adolescents

The primary aim was to examine the effects of a physical activity and nutrition intervention on Body Dissatisfaction, Drive for Thinness, and Weight Concerns in pre-adolescents. Eighty-four 10–12 years old were studied as part of a larger trial of a family-based physical activity and nutrition intervention. Forty-nine children participated in the 8-week intervention (35 in control group) and completed Body Dissatisfaction, Drive for Thinness, and Weight Concerns measures at baseline and post-test. Participants in both groups showed positive but non-significant changes in body image and Drive for Thinness following the trial, but there were no significant between group differences. This was the first study to examine the effects of a physical activity and nutrition intervention on body image and related variables in pre-adolescents. Body Dissatisfaction, Drive for Thinness, and Weight Concerns were not positively or negatively influenced by the intervention.     

Selfie-posting on social networking sites,body surveillance,and exercise for weight control among Chinese young women with low body mass index

Under the perspective of self-perception theory and objectification theory, this study aims to examine the association between selfie-posting on social networking sites (SNSs) and exercise for weight control among Chinese young women, as well as the mediating role of body surveillance. A sample of 467 Chinese female students with a BMI lower than 24 were recruited. Participants voluntarily completed questionnaires assessing their selfie-posting behavior on SNSs, body surveillance, and their weight control motivation for exercise. The results show that selfie-posting on SNSs is positively associated with exercise for weight control, and that body surveillance significantly mediates this association. The results suggest that interventions targeting selfie behaviors on SNSs may be an effective way to prevent unhealthy exercise motivations, such as exercise for weight control, among young women with a low BMI.     

The effects of a brief time perspective intervention for increasing physical activity among young adults

Past research has demonstrated that health behavior is correlated with time perspective: long-term thinkers are more likely than short-term thinkers to engage in health protective behaviors and less likely to engage in health damaging behaviors. To date, however, no research has experimentally demonstrated that time perspective is causally related to health behavior. We designed a brief (three 1/2-h weekly sessions) time perspective intervention to enhance long-term thinking about physical activity and examined its efficacy among two samples of young adults who signed up for fitness classes at a university recreational facility. Participants were assigned to one of three conditions: time perspective intervention, goal-setting control intervention, and no-treatment control. In Study 1, physical activity levels were assessed at preintervention, at postintervention (3 weeks later), and at 10-week follow-up (7 weeks after completion of the intervention). Controlling for preintervention physical activity levels, time perspective participants reported increased levels of physical activity relative to both other groups at postintervention, and relative to the no-treatment group at 10-week follow-up. This study provides the first experimental evidence that the effects of health behavior interventions may be enhanced by increasing participants’ long-term time perspective, and that time perspective is causally associated with health behavior. Study 2 replicated some of the effects of Study 1 using a larger sample, a six-month follow-up interval, and improved measurement of outcome. Together Studies 1 and 2 suggest that time perspective is an important ingredient in interventions designed to promote physical activity.     

The effects of exposure to feminist ideology on women's body image

Body image disturbance has become a common problem among women and there is a need to focus on creating empirically supported treatments. Psychoeducational interventions have reduced body image dissatisfaction, but their impact is limited because they do not offer women adaptive methods of interpreting the many appearance-related messages they receive. This study examined if exposure to a feminist perspective may provide alternative interpretations of cultural messages, thereby increasing body image satisfaction. Participants were randomly assigned to a feminist or psychoeducational intervention, or a control group. Exposure to the feminist condition resulted in increased self-identification as a feminist and greater appearance satisfaction, and changes in feminist identity were related to positive changes in body image. The findings indicate that exposure to feminist theories may serve as an effective intervention strategy.     

The effects of TV commercials using less thin models on young women's mood, body image and actual food intake

This study experimentally tested the effects of exposure to television commercials using less thin models on mood, body focused anxiety and food intake, as compared to the effects of commercials using thin models. In a naturalistic setting, 110 young women were exposed to a neutral movie, interrupted by two commercial breaks. The commercial breaks contained real commercials using either less thin (n = 32) or thin models (n = 39), or neutral commercials (n = 39). During watching television, participants could freely eat snack food. Further, their mood and body focused anxiety was assessed. ANOVAs revealed no effects on body focused anxiety, but women reported a more negative mood and ate less after exposure to commercials using less thin models than after exposure to commercials using thin models. These results imply that using less thin models in commercials explicitly referring to the thin ideal does not make women feel better.     

Body image concern among Australian adolescent girls: The role of body comparisons with models and peers

This study investigated the potential mediating roles of body comparisons with peers and models in the relationship between the internalization of thinness norms and body image concern. A total of 224 Western Australian girls aged 14–15 completed questionnaires assessing their endorsement of thinness norms, body image concerns, and frequency of body comparisons with peers and with models. Both targets of body comparisons were found to significantly mediate the relationship between the endorsement of thinness norms and body image concern, with body comparison with peers a stronger mediator than comparison with models. These findings show that body comparison with peers, in particular, plays a significant role in the experience of body image concerns among adolescent girls, and should be given a higher profile in programs designed to prevent or reduce body image concern.     

The effects of exposure to slender and muscular images on male body dissatisfaction

This research examined the effects of appearance-based comparisons to muscular and slender idealized male bodies and the contribution of internalization and social comparison to change in body dissatisfaction. Participants were 111 male undergraduates who completed measures of body dissatisfaction, internalization, and social comparison and viewed images of either muscular or slender men in advertisements or product-only advertisements. Results indicated that exposure to both muscular and slender images was associated with an increase in body dissatisfaction, with no significant differences in the change in body dissatisfaction between the two image conditions. Internalization and trait social comparison were each associated with an increase in body dissatisfaction; however, upward social comparison was only a significant predictor of a change in body dissatisfaction for the males who viewed muscular images. These results highlight the impact of slender models on young men's body dissatisfaction and support the examination of media literacy interventions with this population.     

The effects of physical activity timing and complexity on episodic memory: A randomized controlled trial

The role of two types of acute physical activity (PA) bouts were assessed on young adults’ free-recall and recognition memory in two experiments, which differed in the temporal relation of PA and word encoding. Before or following training on the Rey Auditory Verbal Learning Task, participants performed a simple two-step dance, a complex four-step dance, or remained seated. Hypotheses proposed that PA prior to encoding and complex PA would enhance PA’s mnemonic benefits. Memory assessed post-PA, 24 h, and 7 days after training indicated that timing and complexity of PA did not impact free-recall or recognition memory. Findings differ from a previous study showing complex PA benefited motor learning more than simple PA (Tomporowski & Pendleton, 2018). The inconsistency may be due to different working memory processes underlying consolidation and retrieval of procedural or episodic information. Theory-based explanations regarding memory storage and retrieval are proposed to elucidate this selective process.     

The effects of goal types on psychological outcomes in active and insufficiently active adults in a walking task: Further evidence for open goals

ObjectivesThis study aimed to extend recent work on the effects of goal types in physical activity (PA; Swann, Hooper et al., 2020) by comparing the effects of SMART, open, and do-your-best (DYB) goals on performance and psychological responses in active and insufficiently active adults in a walking task.Design4 (goal condition) x 3 (attempt) x 2 (group) mixed design.MethodsActive (n = 18) and insufficiently active (n = 18) participants completed baseline and two experimental attempts of a 6-minute walking test in four conditions: SMART goal; open goal; DYB goal; and control. A range of measures were taken during and following each attempt, and after each session. A series of mixed ANOVA’s were conducted for all measures assessed between groups.ResultsInsufficiently active participants achieved greater distances in the open condition compared to the SMART condition (p < .001), whereas active participants achieved greater distances in the SMART condition compared to the open condition (p < .001). Additionally, exploratory analyses revealed that insufficiently active participants reported greater pleasure and enjoyment (p < .05) in the open condition compared to active participants, who conversely reported more pleasure and enjoyment (p < .05) in the SMART condition than insufficiently active participants.ConclusionsFindings provide initial evidence that PA and psychological responses differ between active and insufficiently active individuals depending on goal type. This work has potential implications for goal setting strategies in PA promotion and raises further questions about current practices of setting SMART goals for insufficiently active participants.     

The impact of social relationships on initiation in adapted physical activity for individuals with acquired disabilities

Limited research has explored the factors that promote initiation of adapted physical activity (PA) for individuals with acquired disabilities. Thus, the current paper explores the role of social support in initiating PA among this population. Participants consisted of civilians (n = 15; age: 19–73 years) and military personnel (n = 18; age: 30–68 years) with acquired disabilities (e.g., spinal cord injuries, limb amputation). Two semi-structured interviews were conducted exploring perceptions and participation of adapted sport and PA. An inductive thematic analysis was performed to identify patterns relating to social support and PA initiation. Four social support networks were identified — family, peers, coaches, and community. Findings were presented using creative non-fiction. The results illustrate the complexity and critical value of social support in adapted PA, highlight the nuances that arise in the availability and expression of social, and provides the foundation for further exploration of the significance of social support for people with acquired disabilities.     

The impact of cognitive behavioral therapy on post event processing among those with social anxiety disorder

Individuals with social anxiety are prone to engage in post event processing (PEP), a post mortem review of a social interaction that focuses on negative elements. The extent that PEP is impacted by cognitive behavioral therapy (CBT) and the relation between PEP and change during treatment has yet to be evaluated in a controlled study. The current study used multilevel modeling to determine if PEP decreased as a result of treatment and if PEP limits treatment response for two types of cognitive behavioral treatments, a group-based cognitive behavioral intervention and individually based virtual reality exposure. These hypotheses were evaluated using 91 participants diagnosed with social anxiety disorder. The findings suggested that PEP decreased as a result of treatment, and that social anxiety symptoms for individuals reporting greater levels of PEP improved at a slower rate than those with lower levels of PEP. Further research is needed to understand why PEP attenuates response to treatment.     

The effects of "thin ideal" media on women's body image concerns and eating-related intentions: the beneficial role of an autonomous regulation of eating behaviors

The present study examines the protective role of an autonomous regulation of eating behaviors (AREB) on the relationship between trait body dissatisfaction and women's body image concerns and eating-related intentions in response to “thin ideal” media. Undergraduate women (n = 138) were randomly assigned to view a “thin ideal” video or a neutral video. As hypothesized, trait body dissatisfaction predicted more negative affect and size dissatisfaction following exposure to the “thin ideal” video among women who displayed less AREB. Conversely, trait body dissatisfaction predicted greater intentions to monitor food intake and limit unhealthy foods following exposure to the “thin ideal” video among women who displayed more AREB.     

The effects of secondary tasks that involve listening and speaking on young adult drivers with traits associated with autism spectrum disorders: A pilot study with driving simulation

A driver’s license is key to independence for many young adults, including those with autism spectrum disorders (ASDs). However, individuals with ASDs may face special challenges when learning to drive. If effective driver training is to be devised for this demographic, it is important to determine the nature of these challenges. Driving inherently requires multitasking (e.g. steering, speed maintenance, navigation, hazard detection) and drivers are routinely obligated to combine driving with the demands of listening and responding to others, as occurs during driving lessons. Given that individuals who display traits associated with ASDs may have special difficulties with secondary tasks and especially those that involve socialization, we examined the effects of secondary tasks that involve listening and responding to questions while driving. We compared performance when simply driving (the control condition), driving while listening (the audiobook condition), and driving while listening and speaking (the prompt: answer condition). The autism spectrum quotient (AQ:Baron-Cohen, Wheelwright, Skinner, Martin, & Clubley, 2001), a commonly used self-report questionnaire intended to measure traits associated with ASDs in research, was used to identify young drivers with more and fewer traits related to ASDs in a community sample, (None had a clinical diagnosis of ASD.) Consistent with studies of drivers clinically diagnosed with ASDs, we found that high AQ scorers reported greater mental and physical demand, effort, and frustration when driving, and showed more moment-to-moment variability in lane position and hazard reaction compared to low AQ scorers as measured in a driving simulator. Differences between the low and high scorers were typically largest when secondary tasks were imposed, but the predicted interaction between drive condition and AQ group only emerged in terms of steering variability.
