Correlates of body image dissatisfaction among overweight women seeking weight loss.

Predictors of body image dissatisfaction (BID) among obese people are poorly understood. In 79 obese women seeking weight reduction, associations with BID of self-esteem, youth teasing, adult teasing, and internalization of sociocultural appearance standards (ISAS) were studied. Analyses revealed that only self-esteem, adult teasing, and ISAS predicted BID. Results highlight the importance of adulthood self-esteem and interpersonal--cultural context--rather than childhood experiences--in predicting adulthood BID.

The effects of outcome expectations and satisfaction on weight loss and maintenance: Correlational and experimental analyses-a randomized trial.

This study examines the hypothesis that highly favorable outcome expectations promote weight loss and hinder weight maintenance. To investigate the effects of outcome expectations and satisfaction with treatment outcomes on weight loss, 349 adults were randomly assigned to 1 of 2 weight loss programs that emphasize either (a) an "optimistic" message, focusing exclusively on the positive aspects of weight loss, or (b) a "balanced" message, giving equal time to positive and negative aspects of weight loss. Participants changed their weight loss cognitions in response to the intervention, but there was no significant difference between the intervention treatment groups in short-term or long-term (18-month) weight loss. Independent of treatment message, positive outcome expectations and satisfaction were both associated with weight loss. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The relationship between self-efficacy, attributions, and weight loss in a weight rehabilitation program.

Assessed the relationship between self-efficacy, attributions, and weight loss in the context of a weight rehabilitation program. Pretreatment, posttreatment, and followup assessments of self-efficacy, weight loss, and success–failure attributions were obtained from 38 volunteer overweight women (aged 21–65 yrs) participating in the program. Self-efficacy was significantly enhanced as a result of treatment, although it was not significantly related to weight loss during treatment. However, changes in efficacy expectations during follow-up did coincide with weight change during those intervals. In addition, efficacy expectations alone at treatment termination were found to be a significant predictor of weight loss following a 6-wk and 6-mo follow-up. Success–failure attributions contributed significantly to the prediction of efficacy expectations during treatment and during the 6-wk follow-up. Weight loss during treatment was not a significant determinant of treatment-induced self-efficacy enhancement. Results are interpreted in light of the reciprocal interaction between actual behavior change and cognitive factors in the context of a rehabilitation program.

Planning to lose weight: Randomized controlled trial of an implementation intention prompt to enhance weight reduction among overweight and obese women.

Objective: The trial investigates the effects of augmenting an established weight-reduction intervention with implementation intention prompts. Design: Fifty-five overweight or obese women (ages 18 to 76 years; body mass index from 25.28 to 48.33) enrolled in a commercial weight reduction program were randomly assigned to either an implementation intention prompt or a control condition. Data were collected twice, with a time gap of 2 months. Main Outcome Measures: The primary outcome was participants' change in weight and body mass index from preintervention to follow-up. Results: Repeated measures analysis of variance revealed a significant Time = Condition interaction: On average, implementation intention prompt participants lost 4.2 kg (95% confidence interval = 3.19, 5.07), whereas control participants lost 2.1 kg (95% confidence interval = 1.11, 3.09). The change in frequency of planning mediated the effects of the intervention on weight and body mass index change. Conclusion: Among obese or overweight women participating in a commercial weight loss program, those who learn to form implementation intentions can achieve greater weight reduction. Planning facilitation is a key mechanism explaining enhanced weight loss generated by implementation intention formation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Social-cognitive determinants of physical activity: The influence of social support, self-efficacy, outcome expectations, and self-regulation among participants in a church-based health promotion study.

A social-cognitive model of physical activity was tested, using structural equation analysis of data from 999 adults (21% African American; 66% female; 38% inactive) recruited from 14 southwestern Virginia churches participating in the baseline phase of a health promotion study. Within the model, age, race, social support, self-efficacy, and self-regulation contributed to participants' physical activity levels, but outcome expectations did not. Of the social-cognitive variables, self-regulation exerted the strongest effect on physical activity. Independent of self-regulation, self-efficacy had little effect. Social support influenced physical activity as a direct precursor to self-efficacy and self-regulation. The model provided a good fit to the data and explained 46% of the variance in physical activity among the diverse group of adults. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The moderating effects of performance ambiguity on the relationship between self-efficacy and performance.

Recent research (e.g., Vancouver & Kendall, 2006; Vancouver, Thompson, Tischner, & Putka, 2002; Vancouver, Thompson, & Williams, 2001) has challenged the conventional view of self-efficacy as a positive influence on performance, finding a negative within-person relationship between self-efficacy and performance. In the current study, performance ambiguity is examined as a potential boundary condition for this negative self-efficacy effect. As hypothesized, self-efficacy was negatively related to subsequent performance under conditions of high ambiguity but was positively related to performance when performance ambiguity was low. Additionally, the study evaluates key mediating processes underlying the relationship between self-efficacy and performance, finding support for the role of performance perceptions and effort allocation. The results of this study help to establish the scope of the phenomenon and suggest potential means of inhibiting the negative self-efficacy effects.

Specifying the determinants of the initiation and maintenance of behavior change: An examination of self-efficacy, satisfaction, and smoking cessation.

Using data from smokers (N = 591) who enrolled in an 8-week smoking cessation program and were then followed for 15 months, the authors tested the thesis that self-efficacy guides the decision to initiate smoking cessation but that satisfaction with the outcomes afforded by quitting guides the decision to maintain cessation. Measures of self-efficacy and satisfaction assessed at the end of the program, 2 months, and 9 months were used to predict quit status at 2, 9, and 15 months, respectively. At each point, participants were categorized as either initiators or maintainers on the basis of their pattern of cessation behavior. Across time, self-efficacy predicted future quit status for initiators, whereas satisfaction generally predicted future quit status for maintainers. Implications for models of behavior change and behavioral interventions are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Dynamic effects of self-efficacy on smoking lapses and relapse among adolescents.

Objective: The present study examined whether dynamic day-to-day variations in self-efficacy predicted success in quit attempts among daily smoking adolescents. Design: A sample of 149 adolescents recorded their smoking and self-efficacy three times per day during 1 week prior to and 3 weeks after a quit attempt. Main Outcome Measures: The first lapse, second lapse, and relapse after at least 24 hours of abstinence from smoking were the main outcome measures. Results: Self-efficacy was relatively high and moderately variable prior to the first lapse, but decreased and became more variable thereafter. Lower self-efficacy as measured at the lapse assessment significantly increased the risk that a second lapse and relapse would occur. Individual differences in baseline self-efficacy did not predict any of the treatment outcomes. The time-varying analyses, however, showed that lower self-efficacy on a given day predicted the first lapse, the second lapse, and relapse on the succeeding day. Daily concomitant smoking (any smoking on the preceding day) was not significantly related to relapse. Conclusion: The present results emphasize the importance of self-efficacy among adolescents in cessation and highlight the need for dynamic formulations and assessments of adolescents' self-efficacy and relapse.

The relationship among self-concept, self-efficacy, and performance in mathematics during secondary school.

The relationship among self-concept, self-efficacy, and performance in mathematics was examined among 416 high school students. Participants completed a questionnaire assessing mathematics self-concept and mathematics self-efficacy. Performance was assessed using end-of-term exam results in mathematics. Confirmatory factor analyses supported the existence of two self-concept components--a competency component and an affective component. Self-efficacy items and the competency items of self-concept also loaded on a single factor. Social comparison information was equally influential in the formation of each construct. Self-efficacy beliefs, however, were identified as most highly related with performance in mathematics and percentages. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Childhood abuse and current health problems among older adults: The mediating role of self-efficacy.

Objectives: Child abuse has negative consequences on health functioning and the self-concept. Prior studies have garnered support for these relationships in younger adults; yet few studies have looked at the effects of abuse on health in older adults and the psychosocial variables, specifically self-efficacy, that may influence the abuse-health relationship. Methods: Data obtained from the Physical Health and Disability Study were used to explore the impact of child abuse on current medical problems among older adults who were screened on physical disability status (N = 1396, Mean age = 67, SD = 10.2). The study was conducted in South Florida and used a multiethnic sample that is representative of the general population in this area. Results: Child abuse was associated with the number of current medical problems and disability. Child abuse was also related to lower self-efficacy, and self-efficacy explained the relationship between abuse and the number of health problems. Conclusions: There are far-reaching effects of child abuse on older adults' health and self-concept. Health care providers and gerontologists need to be aware that child abuse is a lifelong risk factor for increased disability and specific health problems, especially among the elderly. Future research should examine treatments designed to increase self-efficacy, especially among those who experienced child abuse, and observe any positive effects on health functioning.

Discriminating among educational majors and career aspirations in Taiwanese undergraduates: The contribution of personality and self-efficacy.

The purpose of this study was to determine whether the Big Five personality factors, measured by the NEO Personality Inventory Five-Factor Inventory (Costa & McCrae, 1992), and vocational confidence across Holland's hexagon, measured by the Skills Confidence Inventory (SCI; Betz, Borgen, & Harmon, 2005), were useful in discriminating among educational majors and career aspirations for 312 Taiwanese university students. The Big Five and confidence, in combination, significantly differentiated among 4 college majors and 7 career aspirations in a Taiwanese university sample. Big Five Agreeableness and SCI Realistic, Investigative, and Conventional confidence emerged as most salient in the discrimination. Differences by sex, major, and career aspiration were mostly consistent with social cognitive career theory, Holland's theory, and prior U.S. research.

Body image and strategies to lose weight and increase muscle among boys and girls.

This study examined factors that influence body image and strategies to either lose weight or increase muscle among children. Participants were 237 boys and 270 girls. Body mass index (BMI), body dissatisfaction, cognitions and behaviors to both lose weight and increase muscles, as well as self-esteem and positive and negative affect, were evaluated. Self-esteem was associated with body satisfaction, positive affect predicted strategies to lose weight and increase muscles, and negative affect predicted body dissatisfaction and cognitions to lose weight and increase muscles. Boys were more likely to focus on changing muscles. Respondents with higher BMIs were more focused on losing weight but not muscle. The discussion focuses on health risk behaviors related to eating and exercise among children. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of depressive symptoms on health behavior practices among older adults with vision loss.

Objective: The authors examined the interface between visual impairment and depressive symptoms on health behaviors, self-care, and social participation among adults ages 65 and older. Method: The authors analyzed data from the 1997–2004 National Health Interview Survey on visual impairment and depressive symptoms for 49,278 adults ages 65 and older, comparing visually impaired adults (n = 8,787) with and without depressive symptoms with a reference group of adults with neither condition (n = 3,136) for outcome measures: physical health, health behaviors, and difficulties with self-care and social participation. Results: Adults with visual impairment and severe depressive symptoms were more likely than adults with neither condition to smoke (14.9%, adjusted odds ratio [AOR] = 1.6), be obese (28.2%, AOR = 1.9), be physically inactive (80.5%, AOR = 3.0), have fair–poor health (76.0%, AOR = 26.5), and have difficulties with self-care (27.9%, AOR = 11.8) and social participation (52.1%, AOR = 10.9). Discussion and Conclusions: Older visually impaired adults with depressive symptoms are vulnerable to health decline and further disablement without timely interventions that target smoking cessation, healthy eating, and increased physical activity.

Long-term relationship between weight and aerobic-fitness change in children.

The relationship between changes in relative weight and fitness was assessed 5 years after children began treatment for obesity. Multivariate regression analysis showed that two factors were independently related to fitness change: (a) maintenance of weight loss from the end of 6 months of treatment to the 5-year follow-up and (b) initial fitness level. Children who showed the largest long-term changes in relative weight and the lowest initial fitness showed the largest improvements in fitness. Short-term weight loss was not related to long-term fitness change. These results show that weight loss and fitness are related over 5 years.

Attitude, social influence, and self-efficacy among Chinese participants of chronic disease self-management program: A latent growth curve modeling study.

Objectives: This study aimed to examine temporal relationships among psychological parameters (readiness to change, changes in self-efficacy [SE], social norm [SN], attitude [AT]) and two self-management behaviors: cognitive symptom management (CSM) and tangible help-seeking (TH) by constructing latent growth change models. Method: This was a longitudinal study of 60 Chinese participants with various chronic diseases who completed a 6-week chronic disease self-management program. Psychological and behavioral variables were assessed at the beginning of the 1st, 4th, and 6th week of the program. Results: Latent growth change curve analysis revealed that, in the early stages of engagement in CSM, SE was a key determinant of behavior. During the 6-week period, changes in SE were influenced directly by both SN and AT. When engaging in TH, SE influenced the behavior with direct and indirect effect from AT and SN. Readiness for change, on the other hand, appeared to be more associated with psychological rather than behavioral changes. This study revealed different underlying change mechanisms for two types of self-management behaviors. Conclusion: The findings shed light on program modifications that could further strengthen the therapeutic effects of the program. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Maintaining large weight losses: The role of behavioral and psychological factors.

Few studies have examined predictors of weight regain after significant weight losses. This prospective study examined behavioral and psychological predictors of weight regain in 261 successful weight losers who completed an 18-month trial of weight regain prevention that compared a control condition with self-regulation interventions delivered face-to-face or via the Internet. Linear mixed effect models were used to examine behavioral and psychological predictors of weight regain, both as main effects and as interactions with treatment group. Decreases in physical activity were related to weight regain across all 3 groups, and increased frequency of self-weighing was equally protective in the 2 intervention groups but not in the control group. Increases in depressive symptoms, disinhibition, and hunger were also related to weight regain in all groups. Although the impact of changes in restraint was greatest in the Internet group and weakest in the face-to-face group, the latter was the only group with increases in restraint over time and consequent decreases in magnitude of weight regain. Future programs should focus on maintaining physical activity, dietary restraints, and frequent self-weighing and should include stronger components to modify psychological parameters.

When self-efficacy negatively relates to motivation and performance in a learning context.

Recent reviews of the training literature have advocated directly manipulating self-efficacy in an attempt to improve the motivation of trainees. However, self-regulation theories conceive of motivation as a function of various goal processes, and assert that the effect of self-efficacy should depend on the process involved. Training contexts may evoke planning processes in which self-efficacy might negatively relate to motivation. Yet the typical between-persons studies in the current literature may obscure the effect. To examine this issue, 63 undergraduate students completed a series of questionnaires measuring self-efficacy and motivation before 5 class exams. Self-efficacy was negatively related to motivation and exam performance at the within-person level of analysis, despite a significant positive relation with performance at the between-persons level.

The mediating role of coping: A cross-sectional analysis of the relationship between coping self-efficacy and coping effectiveness among athletes.

This study examines the relationship among global coping self-efficacy, coping, and coping effectiveness within athletes. We hypothesized that there would be a positive association between coping self-efficacy and coping effectiveness, which would be mediated by coping. It was also predicted that coping strategies within the task-oriented coping dimension would be positively associated with coping effectiveness, whereas strategies from the disengagement- and distraction-oriented coping dimensions would be negatively associated with coping effectiveness. Participants were 353 athletes between the ages of 18 and 29 years, who completed a measure of coping self-efficacy the night before they competed, in addition to a measure of the athletes' use of coping strategies and their perceived coping effectiveness, which was completed immediately after the competitive event. Results revealed that higher global coping self-efficacy scores were significantly (r = .33, p     

A comparison of weight control and weight control plus body image therapy for obese men and women.

Participants were 65 obese men and women who were randomly assigned to either weight control or weight control plus cognitive–behavioral body image therapy. Both conditions showed clinically significant improvements in body image at posttreatment and 1-year follow-up. Adding body image therapy to weight control did not result in greater psychological improvements and did not result in better maintenance of body image change when participants regained weight after treatment. Weight loss and maintenance were equivalent between groups. Adding body image therapy did not improve or detract from weight loss. Although body image therapy has been shown to be effective in obese persons, it appears that a well-rounded cognitive–behavioral weight control program is effective as well.

Motivations for weight loss and behavior change strategies associated with natural recovery from obesity.

Untreated adults (n?=?21) with lengthy weight problem histories who had maintained stable weight loss for a mean of 4.5 years were interviewed and completed questionnaires about their motivations for and behavioral strategies used during weight loss. Currently obese, untreated adults (n?=?20) served as controls. Successful natural recovery was associated with behavior changes like those emphasized in behavioral weight management programs (e.g., healthier food choices, eating more slowly, regular exercise). Motivations for weight loss were largely negative and reflected appearance and psychosocial concerns. Demographic, weight history, and health variables generally did not distinguish the groups. Obesity treatment was widely available but was viewed negatively. These findings reveal natural processes involved in sustained weight loss, highlight the potential importance of separating influences on behavior change from influences on help-seeking, and suggest ways that obesity treatments could be improved to increase their appeal.
