Individual Multimodal Therapy for Weight Loss: A Case Example

Individual multimodal therapy provides a comprehensive approach to the treatment of overeating. The multimodal treatment plan helps to target social and emotional issues related to eating disorders as well as the eating behaviors themselves. The authors present a case study highlighting a treatment model based on a multimodal conceptualization.     

Effects of Prior Juror Experience on Juror Behavior

A psychological assumption underlying the common and legally sanctioned use of jurors with previous jury experience is that such prior experience has little effect on a juror's behavior. The empirical evidence on this assumption is reviewed. Special attention is devoted to recent research that indicates two types of potential bias among experienced jurors. The theoretical and practical implications of this research are discussed.     

Weight Halo Effects: Individual Differences in Perceived Life Success as a Function of Women's Race and Weight

The question of whether or not life success halo effects occur for weight for Black and White women was examined in an experiment using a 2 (race of woman) × 2 (weight of woman) × 2 (sex of participant) design and measures of perceived life success, attractiveness, and personality. The thinner White woman was expected to receive higher life success, attractiveness, and personality ratings than the heavy White woman. However, the heavy Black woman was expected to receive higher ratings than the thinner Black woman. The results were consistent with expectations. These results are discussed in terms of prior research on beauty, weight, and stereotyping.     

Assessing Individual Differences: Effects of Responding to Prior Questionnaires on the Substantive and Psychometric Properties of Self-Esteem and Depression Assessments

It has become a common practice among psychological researchers to administer batteries of individual difference assessments to research participants, although little is known about whether the substantive and psychometric integrity of the questionnaires are maintained when they are administered after the subject has completed other instruments. The studies presented here consider these issues in relation to the assessment of self-esteem and depression. In the first study, college students responsed to a self-esteem inventory (a) by itself (control group), (b) after one prior questionnaire, (c) after three prior questionnaires, or (d) after five prior questionnaires. Results indicated that filling out one or more questionnaires before an assessment of self-esteem resulted in repots of lower self-esteem relative to the control condition. Additional analyses revealed that filling out three or five prior questionnaires created lower reliabilities of subscale scores and lower estimates of concurrent validity between self-esteem and depression. When the effect of prior questionnaires on the General Self-Esteem subscale was examined, the aforementioned results were replicated, and the prior questionnaire treatment created heterogeneous variances across the experimental groups. The second study was designed as a replication of the first study, using an assessment of depression as the target questionnaire. These results revealed that reports of depressive symptomatology increased as the number of prior questionnaires increased. Again, the prior or questionnaire treatment created heterogeneity of variance between the groups, but did not adversely affect its internal consistency.     

Selling Stereotypes: Weight Loss Infomercials,Sexism, and Weightism

Research suggests that television reflects the negative cultural stereotypes of women and heavyweight people. The purpose of this study was to analyze the extent to which paid programming reflects the gender role expectations that have been observed in other kinds of programming and, in particular, the gender representations and weight-stereotypic messages in weight loss infomercials. The results show that images of women outnumbered those of men 2:1, thin women appeared 3 times as frequently as heavyweight women, and the “scientific expert” was always a man. Weight loss infomercials contained more references to unrestricted than to restricted eating, promoted weight loss without exercise more than with exercise, and portrayed heavyweight people as unhappy and unattractive. The implications of the findings for weight-related prejudice and stigma are discussed.     

Framing Political Risks: Individual Differences and Loss Aversion in Personal and Political Situations

People are motivated to avoid losses. In the context of politics, studies consistently show that the threat of losses increases support for risky public policies more than the promise of gains. Here, we predict that this loss aversion is calibrated by individual differences related to one’s ability to accommodate resource loss, and we investigate how these individual differences moderate reactions to the threat of losses and the promise of gains. Results from large-N experiments consistently demonstrate that this moderation effect crucially depends on whether the resource loss relates to oneself or one’s group—whether the setting is personal or political. Consistent with classic assumptions, individuals with inferior abilities to cope with resource loss are more loss averse in personal settings. In political settings where group resources are threatened, effects reverse: Individuals with superior resources and a more central position within the group consistently respond more to the prospect of loss. As discussed, these findings have important implications for our understanding of why and for whom the threat of loss motivates risky personal and political choices. By consequence, the findings also shed novel light on the psychological underpinnings of recent risky political events.      

Levels of Analysis and Effects: Clarifying Group Influence and Climate by Separating Individual and Group Effects

This article addresses conceptual and methodological levels of analysis issues in research on work group and organizational settings. Using organizational climate data, it provides a detailed example of the use of a recent data analysis model (Kenny & La Voie, 1985) which separates individual and group effects. The reanalysis of an earlier study of organizational climate influences on three dependent variables (Giamartino & Wandersman, 1983) revealed that several important relationships between climate dimensions and the dependent variables were masked in the earlier study. Implications for potential misinterpretations within existing group and organizational research are drawn and suggestions for addressing theoretical and measurement problems involving climate research are offered.     

An Appraisal Account of Individual Differences in Emotional Experience

People can differ tremendously in the emotions they experience, both in general as well as in response to specific events, and such differences have large impact on their lives. Based on recent research on individual differences in appraisal and emotion, we propose a framework to understand the basis for individual differences in emotional experience. In this framework, individual differences in how people appraise their circumstances and in how these appraisals are related to emotional experience are seen as crucial in determining how people differ in both contextualized emotional experience and more stable emotional dispositions. We discuss parallels with other explanatory frameworks, implications for the nature of emotion traits, and directions for future research.     

Effects of High Doses of Naltrexone on Running and Responding for The Opportunity to Run in Rats: A Test of the Opiate Hypothesis

Previous research shows that low to moderate doses of opiate antagonists do not affect running whereas high doses decrease running. This decrease in running has been interpreted as a motivational effect; however, it may also be an effect of motoric impairment, malaise, or sedation. The purpose of the present study was to evaluate the effects of high doses of naltrexone on running and responding for the opportunity to run in rats. Seven male Wistar rats, trained to press levers for the opportunity to run for 30 s, were exposed to a series of tandem fixed-ratio 1 variable-interval (VI) schedules of reinforcement where the value of the VI schedule was varied. Four rats were exposed to a VI 60-, VI 30-, and VI 5-s schedule order and the remaining three were exposed to VI 5-, VI 30-, and VI 60-s schedule order. After 50 sessions, doses of 10, 20, or 40 mg/kg of naltrexone were administered prior to a session. Results showed that naltrexone significantly decreased rates of lever pressing and running and increased postreinforcement latency to respond. Within-session analyses showed that naltrexone significantly decreased responding and running during the first schedule of a session regardless of schedule value. The lack of interaction of the drug effect with the schedule of reinforcement is inconsistent with a motivational effect. Consequently, it was concluded that decreases in running caused by high doses of naltrexone are not motivational and should not be taken as evidence in support of the opiate hypothesis.

     

SEX-LINKED BIAS IN PROMOTION DECISIONS: The Role of Candidate's Career Relevance and Respondent's Prior Experience

To investigate the idea that information about relevant career experience has an effect on the degree of sex bias in promotion decisions, an analogue study was conducted in which sex of candidate and relevance of prior jobs were varied. The effect of respondent's experience of subordinacy to a female manager was also investigated. A within-subject design was used with two response formats, ranking and rating. As predicted, relevance of career experience was a primary consideration in the promotion decision. Respondents who had worked in the past under a female manager showed a profemale bias in choosing among candidates with relevant career experience. No sex-linked bias was identified in the treatment of the candidates with irrelevant prior experience. Additional results suggested that the ranking format was more sensitive to the effect of sex-linked bias than was the rating format.     

The Effects of Weight Loss Attempts, Exercise Initiation, and Dietary Practices on Health Related Quality of Life

This study (N = 98) randomly placed participants in either a higher protein or American Heart Association diet group with each group initiating an aerobic exercise program. Body composition (BC) was measured using four different methodologies (DEXA, BIA, skinfold, BMI) along with height and weight, while Health-Related Quality of Life (HRQOL) changes were measured using the Medical Outcomes Short Form 36 (SF-36). There were no significant time/diet interactions in HRQOL scores, body fat measures, and weight with the exception of Role-Physical scores (p = .006) with posttest scores higher in participants in Diet 1. Role-Physical scores changed significantly in participants in Diet 1 (p = .0001) and Diet 2 (p = .026) with higher posttest scores in each group. Social functioning had a significant main effect for time in both groups with pretest scores in both diet groups lower than their respective posttest scores (p = .015). HRQOL pretest scores were not significantly different between groups at baseline (p = .56). ANOVA revealed no significant differences in average calories between groups (p = .88). Analysis revealed no differences in exercise in minutes (p = .66) nor statistically significant changes in BC or weight (p = .65). Conclusions: Improvements in HRQOL were demonstrated in two subscales related to physiological and psychological functioning. These novel findings add to literature suggesting that HRQOL, at least concerning social functioning, work and other daily activities (Role-Physical) may improve by initiating an exercise and dietary program even when weight loss or BC improvements have been unsuccessful.     

The Impact of Case Characteristics and Prior Jury Experience on Jury Verdicts1

An archival analysis of records from 206 criminal cases was used to evaluate the impact of personal and situational factors on jury verdicts. In particular, we evaluated whether repeated jury service produced bias in jurors that was sufficient to affect jury decisions. A variety of case characteristics and indices of prior jury experience was examined for their relative impact on trial outcomes. Several of the case characteristics were related to verdicts, but the personal characteristics were not. Although more than half of the juries contained experienced jurors, juror experience had little influence on verdicts in either major or subsidiary analyses. However, there was a slight tendency for small juries with large proportions of experienced jurors to convict. This result is consistent with data from Kentucky; a meta-analysis across the two data sets indicates that it is a reliable finding. The results have implications for the determination of jury size. We suggest that future research examine the possibility that increasing jury size may reduce the influence of an individual's bias by providing a balance of other jurors with no or offsetting biases.     

Individual Versus Collective Responses to Membership in a Low-Status Group: The Effects of Stability and Individual Ability

Abstract

To test predictions of social identity theory (SIT; M. A. Hogg & D. Abrams, 1988; H. Tajfel & J. C. Turner, 1979) and the 5-stage model (FSM; D. M. Taylor & D. J. McKirnan, 1984) concerning reactions to membership in a low-status group, the authors led 112 pupils to believe that another (anonymous) class outperformed their class. In an overall permeable and legitimate intergroup context, the authors manipulated the stability of the low group status and the individual ability of the group members. Contrary to SIT and FSM, the pupils generally favored collective normative action. Individual mobility was preferred only by group members, especially boys, with high individual ability who thought that the low status of their group was stable. The results support FSM assumptions (a) that individual ability is a powerful determinant of intergroup behavior but (b) that one should consider its impact in combination with perceived stability.     

Considering Weight Loss Programs and Public Health Partnerships in American Evangelical Protestant Churches

The obesity epidemic is a critical public health threat facing the USA. With the advent of American Evangelical Protestant (AEP) weight loss guides and narratives, AEP churches could potentially aid public health agencies in combatting obesity, and some scholars have called for investment in partnerships between public health agencies and religious institutions. This paper examines the theological and social underpinnings of AEP weight loss programs and considers the potential benefits and risks of public health partnerships with AEP churches to combat obesity. While AEP churches may be successful at empowering people to lose weight, AEP weight loss also carries several risks. These risks include reinforcing gendered bodily norms, stigmatizing both overweight bodies and unhealthy behaviors deemed to be sinful (for example, overeating), and failing to acknowledge social factors that promote obesity. These risks must be assessed and minimized to create appropriate public health weight loss partnerships with AEP communities.
