COMPARISON OF ESTABLISHED AND INNOVATIVE WEIGHT-REDUCTION TREATMENT PROCEDURES1

A central component of a commonly used weight-loss procedure developed by Stuart (1967), which emphasizes situational engineering (SE), was compared to eating behavior control (EBC), a treatment employing reinforcement of changes in eating habits. A third treatment encouraged development of individuals' own applications of a model of self-control and attempted to provide effective feedback regarding progress toward weight-loss goals. This self-initiated treatment (SI) was designed to be less directive than many behavioral treatment packages and to be more realistic about the expectations of subjects and the actual eating habits of overweight and normalweight people. Following baseline, treatment lasted six weeks and followup lasted 16 weeks. While all treatments produced weight losses, EBC surpassed SE during treatment. SI losses during treatment did not differ from SE or EBC, but SI was the only group that lost weight throughout followup, indicating the possible utility of more subtle, less directive interventions than those that have often been associated with behavioral approaches. The results of SE question the applicability to clinical procedures of the external cue hypersensitivity theory of obesity (Schachter and Rodin, 1974), to which SE is closely related.     

Understanding the relationships between body esteem,risk for anorexia nervosa,and domain-dependent decision-making impulsivity in a college sample

Impulsivity has been suggested to interact with low body esteem to elevate risk for anorexia nervosa. Discounting tasks are unique tools for examining impulsivity. Female college students (N = 139) at varying levels of body esteem and risk for anorexia nervosa responded to discounting scenarios depicting opportunities to lose/gain weight and to worsen/improve complexion. Multiple regression analyses were used to examine the relationships between impulsivity and risk for anorexia nervosa and body esteem in four disorder-relevant decision-making contexts. Results indicated that lower decision-making impulsivity predicted lower body esteem levels when the outcome of the task was framed as an opportunity to lose weight. It is suggested that greater self-control regarding weight-loss in women with low body esteem may be problematic, placing them at higher risk for eating- and weight-related problems. Results reiterate the need for continued attention to fostering healthy body esteem and weight-control patterns in women on college campuses.     

GENDER DIFFERENCES IN INTERNAL BELIEFS ABOUT WEIGHT AND NEGATIVE ATTITUDES TOWARDS SELF AND OTHERS

Previous research has found that people with an internal weight locus of control (beliefs in self-control over weight) are more likely to join and stay in weight-loss programs and have higher self-esteem than those who have an external locus of control (e.g., belief that weight is due to luck, genes). There has been no research on how weight locus of control affects the self-esteem of people who are not average weight or not satisfied with their weight. The present study predicted that for people who are overweight, weight locus of control would be negatively related to self-esteem. The results confirmed this interaction between weight locus of control and weight on self-esteem for women, but not for men. The second prediction was that internal weight locus of control would have negative social consequences in terms of greater negative stereotyping of obese people, and this was also confirmed for women. Because weight loss is rarely permanent, it would seem important to change people's attitudes about the lack of control that they (and others) have over body weight.

Staff Practices and Social Skill Outcomes in a Sport-Based Youth Program

Staff are key contributors to quality sport-based youth programming. Specific practices leading to positive youth outcomes warrant further investigation. This study examined social skill outcomes resulting from participation in a sport-based youth program, LiFEsports. In addition, relationships among emotional and autonomy supportive staff practices and outcomes were examined. Results pointed to the value of sport-based youth programs for promoting self-control among youth from vulnerable backgrounds and indicated that youth-perceived emotional and autonomy supportive staff practices predicted improvements in perceived self-control but not perceived externalizing behaviors.     

A review of behavioral approaches to weight control

Forty case reports and experimental studies of behavioral approaches to weight control were reviewed. The treatments, categorized as: aversive conditioning, covert sensitization, coverant conditioning, therapist controlled reinforcement and self-control of eating, were evaluated in terms of their empirical support. It was suggested that self-control procedures may be the most promising treatment, particularly when used in conjunction with therapist controlled reinforcement. Methodological difficulties and implications for future research were discussed.     

Understanding supplement use: an application of temporal self-regulation theory

Vitamin and mineral supplement use is increasing worldwide. As evidence of the effects of these practices are equivocal at best, it is important to determine why individuals engage in vitamin and mineral supplement use through the application of a theoretical framework. The aim of this study was to employ temporal self-regulation theory (TST) to establish the determinants of supplement use. A cross-sectional design was used with a sample of 121 individuals who consume vitamins or minerals as dietary supplements. Hierarchical regression analyses were conducted to determine the influence of intention, habit, self-control, and the interaction between intention and habit and self-control on the frequency of supplement use. The model accounted for a significant proportion of variance in behaviour (R² = .44) with intention and habit significantly related to supplement use. Self-control moderated the relationship between intention and behaviour indicating that intention was not related to behaviour when self-control was low. The TST model offers a satisfactory account of supplement use and provides avenues for interventions aimed at increasing safe and beneficial supplement use and decreasing potentially harmful supplement use.     

Tomorrow is the start of the rest of their life — so who cares about health? Exploring constructions of weight-loss motivations and health using story completion

ABSTRACT

In Western societies, health is closely associated with body weight and weight loss, achieved through individual health behaviour. I examined such associations in constructions of weight-loss motivations and health in stories generated using the novel method of story completion. The story stem featured either a female or male protagonist deciding to lose weight; 148 women and 22 men (ages 18–24) provided stories in response. A social constructionist thematic analysis identified five themes: health as clothing size and means to an end; weight-loss activity as good for every woman; tomorrow is going to be the start of the rest of their life; tell me when I’m okay — it’s not about wellbeing; and weight loss as signifier of the “true self.” Considering the adverse social and psychological consequences reflected in the stories and the longstanding elusiveness of successful weight-loss methods, I support calls to review the dominant weight-focused approach to public health.     

Spouse involvement and a possible long-term follow-up trap in weight loss

The present study was conducted to determine if husband attendance at treatment sessions and participation in behavioral contracting would produce greater weight losses than two other levels of spouse involvement. The three treatment groups investigated did not significantly differ at post-treatment but by 1-yr follow-up female Ss who attended treatment sessions alone and contracted with the counselor (HA) lost significantly more weight than women who attended sessions with their husbands and also contracted with the counselor (HNC). The Ss who attended sessions with their husbands and contracted with them (HC) did not significantly differ from Ss in the other two conditions. The total amount lost by Ss in the HA, HNC and HC conditions by 1-yr follow-up was 16.4, 4.4 and 15.5 lb, respectively. The study was also conducted to collect preliminary data about procedures Ss used during long-term follow-up to ascertain if weight losses during follow-up could be attributed to the behavioral weight-loss techniques learned during the treatment program. At all follow-up periods, many Ss reported using behavioral weight-loss techniques but 4 of the 36 Ss (11.1%) at 1-yr follow-up, 15 of the 23 (65.2%) and 24 of the 25 (96.0%) who responded, respectively, at 3- and 4-yr follow-up had used other weight-loss programs or methods. A possible confound for follow-up data was identified and suggestions for future research were presented.     

Does cost–benefit analysis or self‐control predict involvement in bullying behavior by male prisoners?

The main aim of this study is to assess whether lack of self-control or the perceived costs and benefits of aggression provide the better predictors of bullying behavior and victimization, and direct aggression perpetration, in a sample of 122 male British prisoners. We also assessed whether bullying was associated with height and weight. Zero-order correlations showed that perceived benefits, self-control, and perceived costs were most closely associated with perpetration of bullying, and that lack of self-control was weakly associated with victimization. Height and weight were unrelated to bullying or victimization. In a standard regression analyses, perceived benefits was the strongest predictor of bullying perpetration, with lack of self-control contributing further; all three variables made a significant contribution when direct aggression was the criterion. Mediation analysis showed that a combined cost-benefit measure partially mediated the association between self-control and both bullying and direct aggression. The findings are discussed in relation to explanations of aggression based on impulse control or a cost-benefit analysis.

Experiencing Buddhist practices promotes nonbelievers’ preference for future rewards in intertemporal choices

Religious individuals often prefer future rewards more in intertemporal decision-making than nonreligious individuals, but the reasons behind this preference remain under-investigated. Focusing on decision-making in Buddhist culture, the current study aimed to examine three potential mechanisms: Buddhist practices, self-control and belief in future-oriented concepts. In five studies, we consistently found that nonbelievers’ preference ratings for Larger and Later (LL) options increased after visiting a temple (Study 1, n = 99) or participating in Buddha name chanting (Studies 2–5, n = 314). We also found in Studies 3 and 4 that this effect was mediated by the individual's level of self-control, but no evidence was found to support the mediation of belief in future-oriented concepts. These results contribute to the work attesting to the effect of religious practices on individuals (especially nonbelievers). They also provide a mechanism (self-control) for the positive correlation between individuals’ religiousness and preference for future rewards in intertemporal decision-making.     

Behavior change and individual differences in self-control

The use of self-control has become a major emphasis in recent behavioral treatment approaches. This has been especially true for the modification of appetitive disorders: high frequency behavior with immediate positive and delayed negative consequences, such as smoking and overeating. While the results have. for the most part. been promising, they have been marked by a high degree of intersubject variability: even the most generally effective programs have had only selective success (Mahoney, 1972). This variability might well be a function of fundamental interindividual differences in the ability to implement various self-control procedures. Kanfer (1971) has conceptualized self-control as a three component, closed loop process: self-monitoring followed by self-evaluation followed by self-reinforcement. The utilization of each component, the nature of their interaction and their implementation are all learned. Given the complexity of the process and idiosyncratic learning histories, individual differences are to be expected in each component of the self-control sequence. The effectiveness of any therapeutic program emphasizing self-control should, therefore, be a function of the ability and disposition of the patients to implement the self-control sequence or the specifie component required by the procedure. An individual having low facility to administer effective self-reinforcement might, for example, do poorly in a program that required self-reinforcement by containing little or no external supports. Someone who has not learned to accurately selfevaluate might contravene a program by administering self-reinforcement inappropriately.One way to test this contention would be to administer a self-control based treatment to individuals identified as differing in self-control ability: high self-controllers would be expected to do better. That method of attack might, however, be deferred. Lichtcnstein (1971) has suggested that before conducting extensive, elegantly designed treatment research, clinical evidence supporting the efficacy of the procedures be gathered. That approbation can be applied to the evaluation of the general hypothesis presented above, which has not yet had direct empirical support. An alternative, more conservative research strategy would be to precede a treatment study with an examination of individuals who had already changed their own behavior: a process that by definition requires the effective use of self-control. Were the hypothesis valid, differences in the general predisposition (or ability) to emit self-control responses should be observed between individuals who have modified their own behavior (e.g., quit smoking, lost weight) and those unable to do so. The purpose of the present study was to offer some preliminary data on this issue by comparing a group of people who had lost weight or quit smoking with a group that had failed at either. The component of self-control selected for study was self-reinforcement. It was predicted that individuals able to modify their own behavior would have a greater predisposition to use positive self-reinforcement than those unable to do so.

Behavioral techniques in the treatment of obesity: A comparative analysis

The relative efficacy of the major techniques typically used in behavioral treatment programs for weight reduction was investigated using obese adult volunteers. Study 1 compared the effects of self-monitoring, self-control procedures, monetary rewards, aversive imagery and relaxation training. These procedures resulted in significantly greater weight reduction than either a no treatment group or subjects who graphed and recorded daily weight. Self-monitoring of daily caloric intake was as effective as the other methods, both singly and combined, over a 4 week treatment period. Study 2 compared the long-term effects of self-monitoring vs the full complement of behavioral techniques used in Study 1. The full behavior management program was significantly more effective, both during the treatment period and at 3 and 12 week follow-ups, although self-monitoring again produced substantial weight loss.     

Target setting,self-reinforcement pattern and locus of control orientation as predictors of outcome in a behavioural weight-loss programme

High levels of unexplained variance have been reported in the outcome of weight-loss attempts by the obese using dietary and behavioural procedures to lose weight. The present study examined the effects of varying the short-term ‘target’ expectations of weight-loss and the degree of delay of self-reinforcement procedures. Contrary to expectation a significantly greater weight-loss was achieved under ‘unrealistic’ high target levels than under ‘realistic’ lower levels. Delay of self-reinforcement showed no differential effect. Hypothesized interactions between the experimental conditions and an external locus of control orientation were not found but there was a tentative indication that internally controlled individuals do significantly better under the ‘High’ than the ‘Low’ target expectations. The data suggest that more systematic attention should be paid to these cognitive-behavioural variables in planning weight-loss, programmes.     

A temperamental and development model for personality assessment: application to self-control in middle childhood

In personality theory and assessment, it is important to distinguish between dispositional and developmental constructs. This important but often neglected distinction is applied to general personality models, and, specifically, to psychological temperament dimensions and ego development. These conjoined domains are used as a framework to study impulsivity and self-control in a sample of middle-childhood boys. Impulsivity is conceptualized as a temperamental dimension and self-control as an ego-developmental dimension. A factor-analytic procedure was used to test the assumption of orthogonality between impulsivity and self-control. Results were consistent with the hypothesis and provide implications for the concept of ‘difficulty’ of temperament constellations and study of ego development in middle childhood.

Effects of preexisting and manipulated self-efficacy on weight loss in a self-control program

The present study was designed to investigate the effects of self-efficacy on weight loss utilizing self-control techniques. Subjects high and low in preexisting self-efficacy were randomly assigned to high or low manipulated self-efficacy groups in a 2 × 2 (preexisting self-efficacy × manipulated self-efficacy) factorial design. Preexisting self-efficacy was assessed using procedures employed byBandura and Adams (1977, Cognitive Therapy and Research, 1, 287–308). Selfefficacy was manipulated by having subjects attribute successful task performance to a previously unrecognized capacity for self-control. Subjects met in groups once a week for a total of 8 weeks and received a comprehensive weight control program within the context of self-control. Results indicated significant manipulated and preexisting × trials interactions with both the high manipulated and preexisting self-efficacy groups losing more weight over the 8 weeks than the low preexisting and manipulated groups. In addition, locus of control was predictive of weight loss, with internals tending to lose more weight than externals. Results are discussed in terms of Bandura's (1977, Psychological Review, 84, 191–215) theory of self-efficacy.
