The role of self-regulation strategies and self-efficacy perceptions in successful weight loss maintenance

Abstract

The purpose of this study was to identify the self-regulatory strategies which people use to lose, maintain, or manage their weight, and to assess their self-efficacy perceptions to implement these strategies. Thirty-three (N = 33) undergraduate college students were divided into three groups based on their past weight loss experience and confirmed by their current Body Mass Index: (a) overweight participants who tried but failed to lose weight, (b) participants who used to be overweight but lost significant weight and kept it off for at least six months, and (c) participants with an optimal weight. All participants were interviewed using a structured questionnaire. Data were analyzed using a one-way ANOVA and correlation analyses. Participants who used self-regulatory strategies such as goal-setting, self-monitoring, self-evaluation, environmental structuring, time management, social assistance and information seeking were better able to maintain or lose weight. Overweight participants reported significantly less strategy use than participants who had lost weight or who had a healthy weight. In addition, overweight participants had lower self-efficacy perceptions about implementing strategies than did healthy weight participants or participants who had successfully lost weight. Finally, a path analysis revealed that participants who reported high self-efficacy perceptions and applied their strategies persistently in the face of difficulties were more likely to successfully manage their weight.     

Explanations of interindividual – intergroup discontinuity: A review of the evidence

The authors review and evaluate various explanations for the tendency of intergroup relations to be more competitive, or less cooperative, than interindividual relations (the discontinuity effect). They distinguish between two general perspectives, each comprising a set of explanations for the discontinuity effect. The fear and greed perspective assumes that intergroup relations are characterised by greater fear and greed than are interindividual relations. The group decision-making perspective assumes a crucial role for group discussion in facilitating rational comprehension of mixed-motive situations. In general, explanations from the fear and greed perspective were found to be more consistent with the empirical record than explanations from the group decision-making perspective. The authors propose that a complete understanding of the discontinuity effect is yet to be achieved.     

Another view of “we”: Majority and minority group perspectives on a common ingroup identity

Drawing on the evidence of the role of social categorisation and identity in the development and maintenance of intergroup biases, research on the Common Ingroup Identity Model (Gaertner & Dovidio, 2000 Gaertner, S. L. and Dovidio, J. F. 2000. Reducing intergroup bias: The Common Ingroup Identity Model, Philadelphia, PA: The Psychology Press.  [Google Scholar]) has investigated how modifying the ways that the self and others are categorised can reduce prejudice and discrimination. In this article, we review more recent research that extends our initial formulation of the model by considering more fully alternative forms of recategorisation (a dual identity as well as a one-group representation), the different preferences of majority and minority groups for these different forms of recategorised representations, and the potential implications of these different preferences on the content of intergroup interaction and on the possibilities for social change towards equality.     

Superordinate identities and intergroup conflict: The ingroup projection model

This chapter summarises results from a research programme on the psychological basis of tolerance and discrimination in intergroup relations, with particular consideration of the role of superordinate identities. According to the ingroup projection model, a relevant superordinate group provides dimensions and norms for comparisons between ingroup and outgroup. Groups gain positive value or status when they are considered prototypical for the (positively valued) superordinate group. Group members tend to generalise (project) distinct ingroup characteristics onto the superordinate category, implying the relative prototypicality of their ingroup. To the extent that outgroup difference is regarded as a deviation from the ethnocentrically construed prototype it is evaluated negatively. Our research studied consequences and determinants of ingroup projection, as well as moderators of its implications. The findings contribute to a deeper understanding of the processes involved in intergroup discrimination and indicate new pathways for the reduction of prejudice, towards mutual intergroup appreciation and tolerance.     

A social neuroscience approach to self and social categorisation: A new look at an old issue

We take a social neuroscience approach to self and social categorisation in which the current self-categorisation(s) is constructed from relatively stable identity representations stored in memory (such as the significance of one's social identity) through iterative and interactive perceptual and evaluative processing. This approach describes these processes across multiple levels of analysis, linking the effects of self-categorisation and social identity on perception and evaluation to brain function. We review several studies showing that self-categorisation with an arbitrary group can override the effects of more visually salient, cross-cutting social categories on social perception and evaluation. The top-down influence of self-categorisation represents a powerful antecedent-focused strategy for suppressing racial bias without many of the limitations of a more response-focused strategy. Finally we discuss the implications of this approach for our understanding of social perception and evaluation and the neural substrates of these processes.     

Rejecting Sectarianism: Palestinian Christians' Role in Muslim–Christian Relations

The study of Muslim–Christian relations often focuses on Islamic theology and Muslim behavior while overlooking the role that Christians play in shaping interreligious encounters. This article examines a series of historical examples from various periods of Palestinian history that highlight Arab Christians' insistence that they were Palestinian Arabs first and were fully engaged in the nationalist movement. Palestinian Christians' approach to local politics, even in the face of interreligious conflict, allowed them to maintain far better relations with Muslims than Arab Christians in some neighboring Arab countries. By way of comparison, the article highlights the Druze's acceptance of a unique communal relationship to the Zionist leadership and later, to the state of Israel. The article concludes that, while modern Islamism presents a challenge to minority Christian groups, historical examples suggest that Christians' actions have a profound impact on the nature of Christian–Muslim relations.     

Intrinsic Causation in Humean Supervenience

The paper investigates whether causation is extrinsic in Humean Supervenience (HS) in the sense that being caused by is an intrinsic relation between token causes and effects. The underlying goal is to test whether causality is extrinsic for Humeans and intrinsic for anti‐Humeans in this sense. I argue that causation is typically extrinsic in HS, but it is intrinsic to event pairs that collectively exhaust almost the whole of history. 1     

The Relational Genesis of Community: Self–Other Dialogue

Of late, there is increasing interest in the dialogical foundations of the self and community. Indeed, dialogical theory points to the embeddedness of community in self–other relations. This article proposes a dialogical approach to community that draws upon four key themes of discourse: the sociality of the self, the realm of interindividual relations, the constructive role of social representations, and the emergent properties of collective action. The ‘between’ constitutes a valuable concept for theorizing fundamental processes of relational existence and responsive meaning‐making, including the co‐constitution of community. In the process of coming into dialogic relation with one another, individuals construct meanings, experiences, and actions that profoundly shape both selfhood and community. Thus conceived, community is founded on dialogic interaction and intersubjective representation, thereby becoming the conscious object of reflection and action. The intention here is to theorize the relational genesis and continued transformation of community through self–other dialogue. Copyright © 2014 John Wiley & Sons, Ltd.
