Testing overall and moderator effects in random effects meta‐regression

Random effects meta‐regression is a technique to synthesize results of multiple studies. It allows for a test of an overall effect, as well as for tests of effects of study characteristics, that is, (discrete or continuous) moderator effects. We describe various procedures to test moderator effects: the z, t, likelihood ratio (LR), Bartlett‐corrected LR (BcLR), and resampling tests. We compare the Type I error of these tests, and conclude that the common z test, and to a lesser extent the LR test, do not perform well since they may yield Type I error rates appreciably larger than the chosen alpha. The error rate of the resampling test is accurate, closely followed by the BcLR test. The error rate of the t test is less accurate but arguably tolerable. With respect to statistical power, the BcLR and t tests slightly outperform the resampling test. Therefore, our recommendation is to use either the resampling or the BcLR test. If these statistics are unavailable, then the t test should be used since it is certainly superior to the z test.     

Hostile Sexism and Rape Proclivity Amongst Men

In the current study, we examined the influence of victim type and hostile sexism on men’s judgments about an acquaintance rape victim and their self-reported acquaintance rape proclivity. It was predicted that hostile sexism would predict self-reported rape proclivity, but that this relationship would be moderated by victim type. Specifically, it was predicted that participants would report greater proclivity in relation to a victim who appeared not to adhere to traditional gender stereotypes than to a victim who appeared to adhere to such stereotypes. Further, in line with D. Abrams, G. T. Viki, B. Masser, and G. Bohner (2003), it was predicted that the relationship between hostile sexism and rape proclivity would be mediated by perceptions of “token resistance” by the victim. Results partially supported the hypotheses. Hostile sexism was positively related to rape proclivity, but victim type was not found to moderate the relationship. In addition, perceptions of “token resistance” were found to mediate the hostile sexism and rape proclivity relationship. The results suggest that, at least in terms of rape proclivity, hostile sexists may not differentiate in their targets for sexual aggression.     

Intimate partner cohesion and military unit cohesion: Different types of interpersonal relationships each uniquely predict soldier well-being

Although research on military populations has found that measures of personal well-being are correlated with both intimate partner cohesion and military unit cohesion, it is not clear how these correlations should be interpreted. Based on Relationship Regulation Theory, it was expected that each type of interpersonal relationship would have independent effects, that each would uniquely predict outcomes, and that effects would remain significant after controlling for person-level traits and experiences, such as trait resilience and exposure to combat. A sample of 273 active-duty military personnel completed self-report measures of cohesion in two types of interpersonal relationships (intimate relationships and military unit relationships), two control variables (trait resilience and combat exposure), and three outcome variables (well-being, negative emotionality, and trauma-related stress). Results indicated that cohesion in the two types of relationships were minimally related to each other, but both correlated with outcome variables. Effects for each type of interpersonal relationship remained significant after controlling for the other type and controlling for trait resilience and combat exposure. The results suggest that the effects of interpersonal cohesion are best understood as reflecting experiences in specific types of relationships rather than general characteristics of people in those relationships.     

Can the REBT theory explain loneliness? Theoretical and clinical applications

Loneliness is a common psychological experience affecting a significant minority of the general population. Loneliness may in part be related to the existence of dysfunctional cognitive evaluations. To date, however, loneliness has yet to be explicitly assessed within a cognitive-behavioural theoretical framework. The current study sought to determine the association between negative cognitions, within the context of Rational Emotive Behaviour Therapy (REBT), and the experience of loneliness. A multinational sample of university students (n = 397) completed self-report assessments of rational and irrational beliefs, and loneliness. Structural equation modelling results found that the REBT model of psychopathology, and the REBT model of psychological health, provided satisfactory representations of loneliness, explaining 36% and 23% of variance in loneliness, respectively. Several dysfunctional (“Demandingness”, “Catastrophising” and “Self-Downing” beliefs) and functional (“Preferences” and “Self-Acceptance” beliefs) cognitions were directly and indirectly associated with loneliness. These results highlight that cognitions and loneliness are meaningfully related, and indicate that cognitive-behavioural models may be useful in understanding loneliness. More specifically, current results suggest that REBT may offer a viable psychotherapeutic approach to treating loneliness.     

Analysis of Emotions and Dysfunctional Attitudes in Depression

The current study was designed to examine the role of basic emotions and dysfunctional attitudes in depression. Moreover, six models related to the organization of emotions were examined through confirmatory factor analysis. Two hundred individuals with major depressive disorder were recruited from three clinical psychology centers. Participants completed a battery of questionnaires measuring basic emotions, dysfunctional attitudes, and depressive. Results demonstrated that the dysfunctional attitude of “need for approval” and the basic emotions of disgust and sadness could predict depressive scores positively and significantly. It was also shown that the dysfunctional attitudes could positively and significantly predict the two negative emotions of disgust and sadness. Thus, the findings supported an analysis in which the two basic emotions of sadness and disgust were elevated in individuals with depressive disorders. Confirmatory factor analysis supported the proposed basic emotions model and did not support alternative models, such as the positive affect and negative affect model.     

Bullying and victimisation in Scottish secondary schools: Same or separate entities?

Previous research has suggested that bullying is an increasingly severe problem in schools. Such research has approached the phenomenon from two different angles. Earlier research has treated bullying and victimisation as separate entities. However, current research suggests that bullies and victims engage in a special dynamic and interactive relationship, thereby providing the need for studying any similarities and differences between bullies and victims in relation to various factors. The present research has approached bullying and victimisation in both ways. First, we studied differences between bullies, victims, and those not involved in relation to various demographic, school, well‐being, and personality factors to identify factors that separate these three groups. In addition, we studied differences between those involved in bullying/victimisation (one group) and those never involved in relation to the same aforementioned factors to highlight aspects of the development of their special relationship (i.e., common factors). Prevalence rates and types of bullying/victimisation experienced/expressed in Scottish schools were also investigated. It was found that bullying and victimisation, when treated as separate entities, differed in relation to peer self‐esteem, with bullies reporting higher levels of peer self‐esteem than victims. When bullies and victims were treated as one group (involved), they were found to differ from the noninvolved group in relation to various factors, including school, well‐being, and personality factors. The involved group was found to be disadvantaged in relation to all measures used. However, overall results indicated that from all these factors the best predictors of overall involvement as bully, victim, or bully‐victim were Quality of School Life and school stress. The present results support the notion that bullying and victimisation could be treated, by future research, as both separate and/or interactive entities. This is so because bullying and victimisation were found to differ in relation to one personality factor, that is, peer self‐esteem. However, Quality of School Life and school stress, both school factors, were found to be associated with the phenomenon as a whole. Results are discussed in relation to future development of antibullying policy in Scottish schools.Aggr. Behav. 28:45–61, 2002. © 2002 Wiley‐Liss, Inc.     

On the transition from childhood amnesia to the recall of personal memories

When adults are asked to report and date personal memories of their pasts, they show childhood amnesia, that is, diminished recall of experiences over the childhood years. This way of demonstrating the phenomenon was supplemented in the present study with a more direct approach: Participants reported events of early childhood that they knew they had experienced (because of family stories, photographs, etc.) but did not actually remember. The resulting cumulative relative frequency distributions produced by the two methods were substantially different, with the median age of remembered events being 6.07 years and of known events, 3.20 years. We suggest that the mean of these two ages, 4.64 years, gives a good indication of when childhood amnesia is eclipsed by personal memories in adults' recall of their personal pasts.     

A consideration of knowledge and authority in the case seminar

This paper examines difficulties in the management of knowledge and authority evidenced in some case seminar settings. The author suggests that the traditional model for the case seminar has not kept pace with evolving ideas about authority and knowledge in the psychoanalytic situation. The tension between our current ways of conceptualizing knowledge and authority in psychoanalysis, and the often unwitting idealization and constriction of knowledge and authority in the case seminar format, are explored. Following a review of the literature on the case seminar, three recommendations for change are discussed: (1) differentiation of the goals of the seminar from those of supervision; (2) reconsideration of the way in which the 'failed case" is discussed; and (3) encouragement of the instructor to present clinical material.     

Risk preference and choice stochasticity during decisions for other people

In several contexts, such as finance and politics, people make choices that are relevant for others but irrelevant for oneself. Focusing on decision-making under risk, we compared monetary choices made for one’s own interest with choices made on behalf of an anonymous individual. Consistent with the previous literature, other-interest choices were characterized by an increased gambling propensity. We also investigated choice stochasticity, which captures how much decisions vary in similar conditions. An aspect related to choice stochasticity is how much decisions are tuned to the option values, and we found that this was higher during self-interest than during other-interest choices. This effect was observed only in individuals who reported a motivation to distribute rewards unequally, suggesting that it may (at least partially) depend on a motivation to make accurate decisions for others. Our results indicate that, during decision-making under risk, choices for other people are characterized by a decreased tuning to the values of the options, in addition to enhanced risk seeking.
