Meta‐Analysis: A Systematic Method for Synthesizing Counseling Research

The authors provide a template for counseling researchers who are interested in quantitatively aggregating research findings. Meta‐analytic studies can provide relevant information to the counseling field by systematically synthesizing studies performed by researchers from diverse fields. Methodologically sound meta‐analyses require careful planning, diligent literature searches, detailed coding of study information, and knowledge of meta‐analytic approaches to statistical analyses. The authors provide steps to guide counseling researchers in conducting meta‐analytic reviews.     

Children's meta‐perceptions and meta‐accuracy of acceptance and rejection by same‐sex and other‐sex peers

The goals of this study were to examine children's meta‐perceptions and meta‐accuracy of acceptance and rejection in the peer group, the degree to which these perceptions vary by perceiver sex and sex of the reference group, and the association between these perceptions and children's actual functioning in the peer group. Participants were 644 fourth‐grade children. Meta‐perceptions and meta‐accuracy were derived from sociometric nominations of actual and perceived acceptance and rejection. Children more accurately perceived how they were seen by same‐sex peers than how they were seen by other‐sex peers. They also perceived more rejection than acceptance from other‐sex peers. Meta‐accuracy for rejection was low regardless of the sex of the reference group. Sex of the reference group significantly moderated the association between meta‐perceptions and meta‐accuracy of acceptance and rejection and children's actual peer relationships. These findings indicate the importance of examining these relatively understudied social cognitions in research with children and the importance of taking the sex of the reference group into account in future peer relations studies using peer nomination methods.     

Cumulating Evidence about the Social Animal: Meta‐Analysis in Social‐Personality Psychology

Like most scientific fields, social‐personality psychology has experienced an explosion of research related to such central topics as aggression, attraction, gender, group processes, motivation, personality, and persuasion, to name a few. The proliferation of research can be a monster unless it is tamed with the scientific review strategy of meta‐analysis, literally analyses of past analyses that produce a quantitative and empirical history of research on a particular phenomenon. The purpose of this article is to outline the basic process and statistics of meta‐analysis, as they pertain to social‐personality psychology. Meta‐analysis involves: (i) defining the problem under review; (ii) gathering qualified reports and putting their findings and methods into a database, (iii) analyzing that database, and (iv) interpreting the results and reporting them. Use of meta‐analytic strategies has paralleled the knowledge explosion in social‐personality psychology, but must be used and consumed with careful discernment if the cumulated evidence about the social animal, Homo sapiens, is to have maximal value.

Less Adaptive or More Maladaptive? A Meta‐analytic Investigation of Procrastination and Coping

Despite the theoretical and empirical accounts of trait procrastination as reflecting avoidance of aversive tasks as a means of mood repair, research documenting its links to coping is scarce and inconsistent. There is also little if any research to date examining whether coping strategies might explain the procrastination–stress relationship. The current research aimed to address these issues by integrating current research on procrastination and coping with our own data into a first meta‐analysis of the associations of procrastination with adaptive and maladaptive coping and then testing the potential role of coping for understanding the procrastination–stress relationship. In Study 1, a literature search yielded five published papers and three theses, which were supplemented by seven unpublished data sets comprising 15 samples (N = 4357). Meta‐analyses revealed that procrastination was positively associated with maladaptive coping (average r = .31) and negatively associated with adaptive coping (average r = ?.24). In Study 2, a meta‐analysis of the indirect effects through coping across four samples revealed that the average indirect effects for maladaptive but not adaptive coping explained the link between procrastination and stress. These findings expand the nomological network of procrastination and highlight the role of maladaptive coping for understanding procrastinators' stress.

Status‐based expectancies for aggression,with regard to gender differences in aggression in social psychological research

Meta‐analyses of social psychological research have identified gender differences in aggression [Bettencourt and Miller, 1996; Eagly and Steffen, 1986], which have been understood to date in terms of social role theory [Eagly, 1987]. The present studies examined the hypothesis that women's lower status relative to men can account for these observed differences. Participants in Study 1 were presented low‐ and high‐status targets, with status unconfounded with gender, and reported their perceptions of these targets' aggression. Perceptions were for features addressed in the meta‐analyses. As expected, low‐ relative to high‐status individuals were generally perceived in a manner analogous to how women relative to men are portrayed in the meta‐analyses. Participants in Study 2 reported on their perceptions of women's and men's aggression; findings also generally conformed to those of the meta‐analyses. Findings are discussed in terms of a status account of gender. Aggr. Behav. 31:000–000, 2005. © 2005 Wiley‐Liss, Inc.     

In Sync and in Control: A Meta‐Analysis of Parent–Child Positive Behavioral Synchrony and Youth Self‐Regulation

A growing body of research has highlighted the connection between parent–child positive behavioral synchrony and youth self‐regulation; however, this association has yet to be the focus of a meta‐analytic review. Therefore, the present meta‐analysis aimed to estimate the magnitude of the relation between parent–child positive behavioral synchrony and youth self‐regulation and to identify moderator variables that can explain the variability in the degree of this association across the extant literature. A thorough literature search of two major databases, in addition to scanning the reference sections of relevant articles, yielded a total of 10 peer‐reviewed articles (24 effect sizes, 658 children) that were eligible for inclusion in the current meta‐analysis. Results from the overall mean effect size calculation using a random‐effects model indicated that parent–child positive behavioral synchrony was significantly, positively correlated with youth self‐regulation and the effect size was medium. Children's ages at the time of synchrony and self‐regulation measurements, as well as parent gender, served as significant moderator variables. Findings from the present meta‐analysis can help to refine existing theoretical models on the role of the parent–child relationship in youth adjustment. Prevention and intervention efforts may benefit from an increased emphasis on building parent–child positive behavioral synchrony to promote youth self‐regulation and thus children's overall well‐being.     

Meta‐Analysis of Anorexia Nervosa Counseling Outcome Studies From 1990 to 2015

This meta‐analysis of 92 anorexia nervosa counseling articles examined the effectiveness of counseling in reducing symptoms of anorexia nervosa at termination and the longest follow‐up assessments. Treatment‐as‐usual studies showed no effect to small effects at both posttest and follow‐up assessments, wait‐list studies showed small effects at posttest and medium effects at follow‐up, and single‐group uncontrolled studies showed medium to large effects at posttest and medium effects at follow‐up. Implications for research and practice are discussed.

Some recommended statistical analytic practices when reliability generalization studies are conducted

Precursors of the reliability generalization (RG) meta‐analytic approach have not established a single preferred analytic method. By means of five real RG examples, we examine how using different statistical methods to integrate coefficients alpha can influence results in RG studies. Specifically, we compare thirteen different statistical models for averaging reliability coefficients and searching for moderator variables that differ in terms of: (a) whether to transform or not the coefficients alpha, and (b) the statistical model assumed, distinguishing between ordinary least squares methods, the fixed‐effect (FE) model, the varying coefficient (VC) model, and several versions of the random‐effects (RE) model. The results obtained with the different methods exhibited important discrepancies, especially regarding moderator analyses. The main criterion for the model choice should be the extent to which the meta‐analyst intends to generalize the results. RE models are the most appropriate when the meta‐analyst aims to generalize to a hypothetical population of past or future studies, while FE and VC models are the most appropriate when the interest focuses on generalizing the results to a population of studies identical to those included in the meta‐analysis. Finally, some guidelines are proposed for selecting the statistical model when conducting an RG study.     

Are Perfectionism Dimensions Vulnerability Factors for Depressive Symptoms After Controlling for Neuroticism? A Meta‐analysis of 10 Longitudinal Studies

Extensive evidence suggests neuroticism is a higher‐order personality trait that overlaps substantially with perfectionism dimensions and depressive symptoms. Such evidence raises an important question: Which perfectionism dimensions are vulnerability factors for depressive symptoms after controlling for neuroticism? To address this, a meta‐analysis of research testing whether socially prescribed perfectionism, concern over mistakes, doubts about actions, personal standards, perfectionistic attitudes, self‐criticism and self‐oriented perfectionism predict change in depressive symptoms, after controlling for baseline depression and neuroticism, was conducted. A literature search yielded 10 relevant studies (N = 1,758). Meta‐analysis using random‐effects models revealed that all seven perfectionism dimensions had small positive relationships with follow‐up depressive symptoms beyond baseline depression and neuroticism. Perfectionism dimensions appear neither redundant with nor captured by neuroticism. Results lend credence and coherence to theoretical accounts and empirical studies suggesting perfectionism dimensions are part of the premorbid personality of people vulnerable to depressive symptoms.

On the Iatrogenic Risk of Assessing Suicidality: A Meta‐Analysis

Previous studies have failed to detect an iatrogenic effect of assessing suicidality. However, the perception that asking about suicide may induce suicidality persists. This meta‐analysis quantitatively synthesized research concerning the iatrogenic risks of assessing suicidality. This review included studies that explicitly evaluated the iatrogenic effects of assessing suicidality via prospective research methods. Thirteen articles were identified that met inclusion criteria. Evaluation of the pooled effect of assessing suicidality with regard to negative outcomes did not demonstrate significant iatrogenic effects. Our findings support the appropriateness of universal screening for suicidality, and should allay fears that assessing suicidality is harmful.     

Beliefs and environmental behavior: The moderating effect of emotional intelligence

Recent decades have seen a proliferation of studies aiming to explain how pro‐environmental behavior is shaped by attitudes, values and beliefs. In this study, we have included an aspect in our analysis that has been rarely touched upon until now, that is, the intelligent use of emotions as a possible component of pro‐environmental behavior. We applied the Trait Meta Mood Scale‐24 (TMMS‐24) and the New Environmental Paradigm scale to a sample of 184 male and female undergraduate students. We also carried out correlation and hierarchical regression analyses of blocks. The results show the interaction effects of the system of environmental beliefs and the dimensions of emotional intelligence on glass recycling attitudes, intentions and behavior. The results are discussed from the perspective of research on how the management of emotions guides thought and behavior.     

How do I see myself? A systematic review of identities in pro‐environmental behaviour research

Encouraging pro‐environmental behaviour (PEB) is an environmental and societal concern. Encouraging PEB focussing on how consumers see themselves (their identity) has blossomed. However, a theoretical assessment of this research is missing. Three main identity theories seem to best explain the research, specifically, and two‐fold, identity, and social identity theory (SIT), collectively known as the unified identity theory (UIT), and place identity theory (PIT). As these theories overlap more than differ in their understanding of identity, we argue that combining these theories is needed to avoid redundancies in identity theorizing, provide a universal approach to identity in terms of the processes and outcomes, and explain the PEB research most succinctly. Therefore, we understand identity similarly between the theories and offer a universal identity theory approach based on the theoretical definitions and assumptions. Finally, we demonstrate how the theory can be used to explain the research. Next, research was identified by conducting a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines, where 62 studies were relevant. Multiple identities relevant for a given PEB are assumed and evidenced: 99. Identities are assumed to be either individually‐, group‐, and/or place‐focused, drawing on the specific subsets of the universal theory: identity theory, social identity theory, and place identity theory, respectively. Identities are assumed to relate to behaviour, where identity increased PEB with medium effect sizes. Finally, to move the field forward, we provide a theoretical framework of how to test identities in relation to other psychological variables relevant for PEB research.     

The Discursive Performance of Change Process in Systemic and Constructionist Therapies: A Systematic Meta‐Synthesis Review of In‐Session Therapy Discourse

Despite the emphasis of systemic and constructionist approaches on discourse and interaction, to date there has been no comprehensive overview of how change process is performed within in‐session therapeutic dialogue. In this paper, we present a qualitative meta‐synthesis of 35 articles reporting systemic and constructionist therapy process data from naturally occurring therapeutic dialogue. The studies were selected following the screening against eligibility criteria of a total sample of 2,977 studies identified through a systematic search of PsycINFO and MEDLINE databases. Thematic analysis of the 35 studies’ findings identified four main themes depicting change process performance: (a) shifting to a relational perspective, (b) shifting to non‐pathologizing therapeutic dialogue, (c) moving‐forward dialogue, and (d) the dialogic interplay of power. Findings highlight the interactional and discursive matrix within which systemic and constructionist change process occurs. Findings illuminate the value of qualitative research studies sampling naturally occurring therapeutic discourse in bringing this matrix forth, particularly when utilizing discursive methodologies like conversation or discourse analysis.     

Statin Use,Ageing, and Cognition: A Review

Cholesterol performs a number of important roles in normal brain functioning, including the formation of myelin sheaths and communication between cells, and it has been theorised that statin use could disrupt these roles leading to deficits in cognition. Relevant research was identified via the La Trobe University library Summon^TM search tool, using search terms including “statin cognition,” “statins cognition,” “statin brain,” “cholesterol cognition,” “cholesterol brain,” and “statin adverse effects” in addition to examination of the reference lists of the retrieved research articles. Research was examined from the published literature across several different research modalities: systematic reviews and meta‐analyses, randomised control trials, cohort studies, and case reports. On the basis of the surveyed literature, it is not possible to indicate any consistent caution or limitation with regard to the use of statins and their effects upon cognitive functioning due to the contradictory and inconsistent results arising from this literature. In summary, it is not possible to conclusively determine whether there are either cognitive benefits or detriments associated with the use of the statins. The determination of the effect of these agents on neuropsychological functioning requires more methodologically controlled long‐term longitudinal follow‐up studies of these treatments due to the complex and multisystem effects of these agents.     

Does your mindfulness benefit others? A systematic review and meta‐analysis of the link between mindfulness and prosocial behaviour

Mindfulness‐based meditation practices have received substantial scientific attention in recent years. Mindfulness has been shown to bring many psychological benefits to the individual, but much less is known about whether these benefits extend to others. This meta‐analysis reviewed the link between mindfulness – as both a personality variable and an intervention – and prosocial behaviour. A literature search produced 31 eligible studies (N = 17,241) and 73 effect sizes. Meta‐analyses were conducted using mixed‐effects structural equation models to examine pooled effects and potential moderators of these effects. We found a positive pooled effect between mindfulness and prosocial behaviour for both correlational (d = .73 CI 95% [0.51 to 0.96]) and intervention studies (d = .51 CI 95% [0.37 to 0.66]). For the latter, medium‐sized effects were obtained across varying meditation types and intensities, and across gender and age categories. Preliminary evidence is presented regarding potential mediators of these effects. Although we found that mindfulness is positively related to prosociality, further research is needed to examine the mediators of this link and the contexts in which it is most pronounced.     

Partner's understanding of affective–cognitive meta‐bases predicts relationship quality

Knowledge that partners have about each other's attitudes are consequential for relationship quality. This article extends prior research and examines whether knowledge regarding a partner's meta‐attitudinal bases, or subjective perceptions of how one's attitudes are driven, can influence relationship quality. Given how meta‐bases are reflective of information‐processing goals, we hypothesized that partner understanding of meta‐attitudinal bases would positively predict relationship quality. Self and partner ratings of how relationally relevant attitudes were driven, as well as perceptions of relationship quality, were assessed. Results revealed that a partner's knowledge of one's meta‐bases positively predicts one's own reported relationship quality. Results remained significant when controlling for relationship duration and meta‐bases similarity. Implications of meta‐bases understanding for close relationship functioning are discussed.
