The long‐term effect of social comparison on academic performance

The present study was part of a large‐scale cohort study among several thousand students in the Netherlands. The purpose of the study was to investigate the long‐term effects of comparison choice, i.e., comparison with a target performing better or worse than oneself, and academic comparative evaluation, i.e., the extent to which one thinks one's performance is better or worse than that of others, on scores on standardized tests for reading comprehension and mathematics. While controlling for earlier performance, the results showed that both comparison choice and academic comparative evaluation positively predicted test scores over a period of 2 years. Moreover, it was found that the positive effect of comparison choice only applied to students with a favorable comparative evaluation. Copyright © 2009 John Wiley & Sons, Ltd.     

Quitting smoking: The importance of non-smoker identity in predicting smoking behaviour and responses to a smoking ban

Objective: We examined how ‘smoker’ and ‘non-smoker’ self- and group-identities and socio-economic status (SES) may predict smoking behaviour and responses to antismoking measures (i.e. the Dutch smoking ban in hospitality venues). We validated a measure of responses to the smoking ban.

Design: Longitudinal online survey study with one-year follow-up (N = 623 at T1 in 2011; N = 188 at T2 in 2012) among daily smokers.

Main outcome measures: Intention to quit, quit attempts and ‘rejecting’, ‘victimizing’, ‘socially conscious smoking’ and ‘active quitting’ responses to the smoking ban.

Results: Non-smoker identities are more important than smoker identities in predicting intention to quit, quit attempts and responses to the smoking ban, even when controlling for other important predictors such as nicotine dependence. Smokers with stronger non-smoker identities had stronger intentions to quit, were more likely to attempt to quit between measurements, and showed less negative and more positive responses to the smoking ban. The association between non-smoker self-identity and intention to quit was stronger among smokers with lower than higher SES.

Conclusion: Antismoking measures might be more effective if they would focus also on the identity of smokers, and help smokers to increase identification with non-smoking and non-smokers.     

Self-efficacy expectations with regard to different tasks in smoking cessation

Abstract

Self-efficacy expectations are important psychological determinants of smoking cessation. The present study aimed at exploring different sorts of self-efficacy. The following self-efficacy scales were composed: Emotional self-efficacy, Social self-efficacy, Skill self-efficacy, Relapse self-efficacy and Try self-efficacy. In a sample of 752 smokers with low motivation to quit, two subsequent self-report measurements of self-efficacy were conducted. Firstly, we investigated to what extent potential sources of self-efficacy - quitting history and smoking behavior -were related to the types of self-efficacy. The explained variance in self-efficacy scores ranged from 4.4% to 23.1%, and in all five types of self-efficacy, smoking behaviour explained a higher percentage of self-efficacy than quitting history. The number of past quit attempts was only related to Relapse self-efficacy. Secondly, we investigated to what extent the different types of self-efficacy at T1 were predictive of quitting behavior measured at T2. The results showed that only Skill self-efficacy was predictive of quitting activity between Tl and T2. Point prevalence quitting at T2 was predicted by Skill self-efficacy and Relapse self-efficacy. The latter type of self-efficacy, however, was a negative predictor of quitting. The different types of self-efficacy can be mapped on two dimensions: The extent to which the means to accomplish a certain task are specified in the questionnaire item; and the phase of behavior change to which the self-efficacy tasks are relevant. Based on the findings from the predictive validity, it is concluded that the more clearly the means to accomplish the task are specified, the more valid the self-efficacy judgements are.     

Eye movement inductions influence health behaviour: the working memory account of persuasion

Abstract

Objective: Because the working memory (WM) has a limited capacity, the cognitive reactions towards persuasive information in the WM might be disturbed by taxing it by other means, in this study, by inducing voluntary eye movements (EMi). This is expected to influence persuasion.

Methods: Participants (N?=?127) listened to an auditory persuasive message on fruit and vegetable consumption, that was either framed positively or negatively. Half of them was asked to keep following a regularly moving dot on their screen with their eyes. At pretest, cognitive self-affirmation inclination (CSAI) was assessed as individual difference to test possible moderation effects.

Results: The EMi significantly lowered the quality of the mental images that participants reported to have of the persuasive outcomes. With regard to self-reported fruit and vegetable consumption after two weeks, EMi significantly lowered consumption when CSAI was high but it significantly increased consumption when CSAI was low.

Conclusions: The results verify our earlier findings that induced EM can influence persuasion. Although it remains unclear whether the effects of EMi were caused by disturbing mental images of persuasive outcomes or self-regulative reactions to these images, or both, the WM account may provide new theoretical as well as practical angles on persuasion.     

Age and Gender Differences in Mate Selection Criteria for Various Involvement Levels

The present study investigated mate preferences for five different levels of relationship involvement—marriage, serious relationship, falling in love, casual sex, and sexual fantasies–among individuals of 20, 30, 40, 50, and 60 years of age. Consistent with an evolutionary perspective, men preferred mates who were higher in physical attractiveness than themselves, whereas women preferred mates who were higher in income, education, self–confidence, intelligence, dominance, and social position than themselves. The lower the level of relationship involvement, the lower were the preferred levels of education, physical attractiveness, and, particularly for males, preferred intelligence in comparison to oneself. For sexual fantasies, men and women preferred mates who were higher in physical attractiveness than those they preferred for real partners. There were few age differences in mate preferences, although older individuals set higher standards for a potential mate’s education.     

Conditions for factor (in)determinacy in factor analysis

The subject of factor indeterminacy has a vast history in factor analysis (Guttman, 1955; Lederman, 1938; Wilson, 1928). It has lead to strong differences in opinion (Steiger, 1979). The current paper gives necessary and sufficient conditions for observability of factors in terms of the parameter matrices and a finite number of variables. Five conditions are given which rigorously define indeterminacy. It is shown that (un)observable factors are (in)determinate. Specifically, the indeterminacy proof by Guttman is extended to Heywood cases. The results are illustrated by two examples and implications for indeterminacy are discussed.     

Counselees’ Expressed Level of Understanding of the Risk Estimate and Surveillance Recommendation are Not Associated with Breast Cancer Surveillance Adherence

We studied counselees’ expressed understanding of the risk estimate and surveillance recommendation in the final consultation for breast cancer genetic counseling in relation with their risk perception, worry and cancer surveillance adherence 1 year post-counseling. Consecutive counselees were included from 2008 to 2010. Counselees with an indication for diagnostic DNA-testing for themselves or a breast cancer affected relative were requested to complete online questionnaires before and after counseling and one year after counseling (N?=?152–124). Self-reported surveillance was compared to surveillance recommendations. Consultations were videotaped. Counselees’ reactions to the risks and recommendations were coded. Statements about the risk perception and surveillance intentions of breast cancer unaffected counselees were transcribed. Associations with outcomes were explored. Almost all breast cancer unaffected counselees (>90 %) reacted to their risk estimate with an utterance indicating understanding and this reaction was not significantly associated with their post-visit risk perception alignment. Over one-third (38.6 %) overestimated their risk post-counseling. Few counselees (5.8 %) expressed surveillance intentions. One year after counseling, about three-quarters (74.0 %) of the breast cancer unaffected counselees had adhered to the surveillance recommendation. Almost one-quarter (23.3 %) had performed more mammograms/MRI scans than recommended, which was associated with prior mammography uptake (n?=?47; X ² ?=?5.2; p?=?.02). Counselees’ post-counseling overestimation of their risk, high levels of worry and high surveillance uptake were not reflected in their reactions to the counselor’s information during the final visit.     

Examining a model of dispositional mindfulness, body comparison, and body satisfaction

The present study examined the links between dispositional mindfulness, body comparison, and body satisfaction. It was expected that mindfulness would be associated with less body comparison and more body satisfaction. Two models were tested: one exploring body comparison as a mediator between mindfulness and body satisfaction and an alternative model exploring mindfulness as a mediator between body comparison and body satisfaction. In an online survey, 1287 Dutch women answered questions concerning dispositional mindfulness, body comparison, and body satisfaction. Results showed that body comparison was related negatively to both dispositional mindfulness and body satisfaction, whereas the two latter variables were related positively. Body comparison partially mediated the relation between mindfulness and body satisfaction. However, a stronger indirect effect was noted in the alternative model, where mindfulness partially mediated the link between body comparison and body satisfaction.     

The Importance of Ethical Appraisal in Social Science Research: Reviewing a Faculty of Humanities’ Research Ethics Committee

Research Ethics Committees (RECs) or Institutional Review Boards (IRBs) are rapidly becoming indispensable mechanisms in the overall workings of university institutions. In fact, the ethical dimension is an important aspect of research governance processes present in institutions of higher learning. However, it is often deemed that research in the social sciences do not require ethical appraisal or clearance, because of the alleged absence of harm in conducting such research. This is an erroneous and dangerous assumption given that research in social sciences poses various and complex dilemmas related to ethics. The article aims to gauge the importance of ethical appraisal at a particular institution of higher learning’s Faculty of Humanities. This is done by scrutinising its defunct REC, and the views that Heads of Departments of the Faculty have of ethics in research and the need for ethical appraisal by this REC. Finally, some suggestions are made to proceed to review and restructure the current REC with the ultimate objective to make it functional again. It was found that the development and discussion around ethics in research and ethical appraisal are part of a much needed thrust to sensitise the entire Faculty and the institution on the widespread beneficial repercussions of ethical awareness in research and beyond.     

Beyond the Class Norm: Bullying Behavior of Popular Adolescents and its Relation to Peer Acceptance and Rejection

This study examined to what extent bullying behavior of popular adolescents is responsible for whether bullying is more or less likely to be accepted or rejected by peers (popularity-norm effect) rather than the behavior of all peers (class norm). Specifically, the mean level of bullying by the whole class (class norm) was split into behavior of popular adolescents (popularity-norm) and behavior of non-popular adolescents (non-popularity-norm), and examined in its interaction with individual bullying on peer acceptance and peer rejection. The data stem from a peer-nominations subsample of TRAILS, a large population-based sample of adolescent boys and girls (N = 3312). The findings of multilevel regression analyses demonstrated that the negative impact of individual bullying on peer acceptance and the positive impact on peer rejection were particularly weakened by bullying by popular adolescents. These results place the class-norm effects found in previous person-group dissimilarity studies in a different light, suggesting that particularly bullying by popular adolescents is related to the social status attached to bullying.
