Meta-analytic Review (meta-analytic + review)
Selected AbstractsInterparental Conflict and Parenting Behaviors: A Meta-Analytic ReviewFAMILY RELATIONS, Issue 1 2000Ambika Krishnakumar The purpose of this study is to examine the association between interparental conflict and parenting using meta-analytic review techniques. One-hundred and thirty-eight effect sizes from 39 studies are analyzed. The overall average weighted effect size is ,.62, indicating a moderate association and support for the spillover hypothesis. The parenting behaviors most impacted by interparental conflict are harsh discipline and parental acceptance. Several moderating effects for subject and method characteristics are significant. [source] Attitudes Toward Younger and Older Adults: An Updated Meta-Analytic ReviewJOURNAL OF SOCIAL ISSUES, Issue 2 2005Mary E. Kite This meta-analytic review of 232 effect sizes showed that, across five categories, attitudes were more negative toward older than younger adults. Perceived age differences were largest for age stereotypes and smallest for evaluations. As predicted by social role theory (Eagly, 1987), effect sizes were reduced when detailed information was provided about the person being rated. The double standard of aging emerged for evaluations and behavior/behavioral intentions, but was reversed for the competence category. Perceptions depended on respondent age also. Results demonstrated both the multi-dimensionality and the complexity of attitudes toward older adults (Hummert, 1999; Kite & Wagner, 2002). [source] Anger Treatment for Adults: A Meta-Analytic ReviewCLINICAL PSYCHOLOGY: SCIENCE AND PRACTICE, Issue 1 2003Raymond DiGiuseppe We included 50 between-group studies with control groups and 7 studies with only within-group data in a meta-analysis of adult anger treatments. Overall, we examined 92 treatment interventions that incorporated 1,841 subjects. Results showed that subjects who received treatment showed significant and moderate improvement compared to untreated subjects and a large amount of improvement when compared to pretest scores. In the group of controlled studies significant heterogeneity of variance and significant differences among effect sizes for different dependent variable categories were found. Anger interventions produced reductions in the affect of anger, reductions in aggressive behaviors, and increases in positive behaviors. An analysis of follow-up data suggested that treatment gains were maintained.

Mania associated with antidepressant treatment: comprehensive meta-analytic review. Objective:, To review available data pertaining to risk of mania,hypomania among bipolar (BPD) and major depressive disorder (MDD) patients with vs. without exposure to antidepressant drugs (ADs) and consider effects of mood stabilizers. Method:, Computerized searching yielded 73 reports (109 trials, 114 521 adult patients); 35 were suitable for random effects meta-analysis, and multivariate-regression modeling included all available trials to test for effects of trial design, AD type, and mood-stabilizer use. Results:, The overall risk of mania with/without ADs averaged 12.5%/7.5%. The AD-associated mania was more frequent in BPD than MDD patients, but increased more in MDD cases. Tricyclic antidepressants were riskier than serotonin-reuptake inhibitors (SRIs); data for other types of ADs were inconclusive. Mood stabilizers had minor effects probably confounded by their preferential use in mania-prone patients. Conclusion:, Use of ADs in adults with BPD or MDD was highly prevalent and moderately increased the risk of mania overall, with little protection by mood stabilizers. [source] Effects of Explanations on Applicant Reactions: A meta-analytic reviewINTERNATIONAL JOURNAL OF SELECTION AND ASSESSMENT, Issue 4 2009Donald M. Truxillo One cost effective way to improve applicant reactions is by giving explanations. Although a literature on this topic has accumulated, the effects of explanations on applicant reactions have not been examined meta-analytically, and several aspects of giving explanations to applicants are unclear. For example, do explanations affect applicant reactions, and which outcomes are most affected? Do findings from lab studies generalize to field settings? Under what conditions are explanations most effective? To answer these questions, we meta-analytically examined the effects of providing explanations on applicant reactions. Based on 26 distinct samples from experiments and quasi-experiments (N=3481), our results suggest that explanations do affect applicants' fairness perceptions, perceptions of the hiring organization, test-taking motivation, and performance on cognitive ability tests. The effects on fairness are larger in field contexts than in lab settings and when they are used with a personality test rather than a cognitive ability test. Test-taking motivation mediated the relationship between explanations and test performance. Our discussion focuses on when to provide explanations to applicants in employment settings and directions for future research. [source] The Convergent Validity between Self and Observer Ratings of Personality: A meta-analytic reviewINTERNATIONAL JOURNAL OF SELECTION AND ASSESSMENT, Issue 1 2007James J. Connolly The convergent validity between self and observer ratings of the Big Five dimensions of personality was examined by cumulating research findings across studies. The mean correlation corrected for coefficient , in self-ratings and inter-rater reliability in observer ratings was .46 for agreeableness (N=6359, k=53), .56 for conscientiousness (N=6754, k=58), .51 for emotional stability (N=8000, k=55), .62 for extraversion (N=7725, k=50), and .59 for openness to experience (N=5333, k=38). Results indicate that, although there is a high degree of construct overlap, both self and observer ratings have substantial unique variance. Moderator effects were analyzed. The duration of acquaintance (strangers vs close relatives) as well as observer type (peers at work vs relatives) were analyzed. Acquaintanceship had a large moderating effect whereas observer type did not moderate the level of convergence. [source] The impact of client treatment preferences on outcome: a meta-analysisJOURNAL OF CLINICAL PSYCHOLOGY, Issue 4 2009Joshua K. Swift Abstract An important part of evidence-based practice is to include client preferences in the treatment decision-making process. However, based on previous reviews of the literature there is some question as to whether including client preferences actually has an effect on treatment outcome. This meta-analytic review summarized data from over 2,300 clients across 26 studies comparing the treatment outcome differences between clients matched to a preferred treatment and clients not matched to a preferred treatment. The findings indicate a small significant effect (r=.15, CI.95: .09 to .21) in favor of clients who received a preferred treatment. The binomial effect size indicated that matched clients have a 58% chance of showing greater improvement, and further analysis indicate that they are about half as likely to drop-out of treatment when compared with clients not receiving a preferred treatment. Study design was seen to be a moderating variable in that partially randomized preference trials may underestimate the treatment preference effect. Implications for best practice standards are discussed. © 2009 Wiley Periodicals, Inc. J Clin Psychol 65:1,14, 2009. [source] Towards a multi-foci approach to workplace aggression: A meta-analytic review of outcomes from different perpetrators,JOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 1 2010M. Sandy Hershcovis Using meta-analysis, we compare three attitudinal outcomes (i.e., job satisfaction, affective commitment, and turnover intent), three behavioral outcomes (i.e., interpersonal deviance, organizational deviance, and work performance), and four health-related outcomes (i.e., general health, depression, emotional exhaustion, and physical well being) of workplace aggression from three different sources: Supervisors, co-workers, and outsiders. Results from 66 samples show that supervisor aggression has the strongest adverse effects across the attitudinal and behavioral outcomes. Co-worker aggression had stronger effects than outsider aggression on the attitudinal and behavioral outcomes, whereas there was no significant difference between supervisor, co-worker, and outsider aggression for the majority of the health-related outcomes. These results have implications for how workplace aggression is conceptualized and measured, and we propose new research questions that emphasize a multi-foci approach.

[source] Relationships between psychological climate perceptions and work outcomes: a meta-analytic reviewJOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 4 2003Christopher P. Parker In this study, meta-analytic procedures were used to examine the relationships between individual-level (psychological) climate perceptions and work outcomes such as employee attitudes, psychological well-being, motivation, and performance. Our review of the literature generated 121 independent samples in which climate perceptions were measured and analyzed at the individual level. These studies document considerable confusion regarding the constructs of psychological climate, organizational climate, and organizational culture and reveal a need for researchers to use terminology that is consistent with their level of measurement, theory, and analysis. Our meta-analytic findings indicate that psychological climate, operationalized as individuals' perceptions of their work environment, does have significant relationships with individuals' work attitudes, motivation, and performance. Structural equation modeling analyses of the meta-analytic correlation matrix indicated that the relationships of psychological climate with employee motivation and performance are fully mediated by employees' work attitudes. We also found that the James and James (1989) PCg model could be extended to predict the impact of work environment perceptions on employee attitudes, motivation, and performance. Despite the number of published individual-level climate studies that we found, there is a need for more research using standardized measures so as to enable analyses of the organizational and contextual factors that might moderate the effects of psychological climate perceptions. Finally, we argue for a molar theory of psychological climate that is rooted in the psychological processes by which individuals make meaning or their work experiences.

[source] A meta-analytic review of obesity prevention in the schools: 1997,2008PSYCHOLOGY IN THE SCHOOLS, Issue 8 2009Catherine Cook-Cottone A meta-analysis was conducted on school-based interventions to reduce obesity in children. Sixty-six (k = 66, N = 31,059) comparisons from 40 published studies from 1997 through 2008 were included in analyses. Results indicated a significant effect for school-based interventions with an overall weighted effect size of r = .05. Several moderating factors were examined to explain the heterogeneity in study outcomes. Interventions that were universal (k = 37, r = .07), conducted in elementary schools (k = 41, r = .06), implemented collaboratively (k = 19, r = .12), primarily included children of Asian ethnicity (k = 5, r = .30), encouraged nutritional change (k = 28, r = .13), and sought to reduce sedentary behaviors (k = 17, r = .15) were identified as more successful in reducing students' obesity-related outcomes. Factors that resulted in negative effects for school-based programs included interventions of short duration (k = 11, r = ,.04) and those that implemented system-wide changes in nutrition (k = 15, r = ,.03). The variability in study effect sizes is discussed, and recommendations are made for future school-based interventions targeting children. © 2009 Wiley Periodicals, Inc. [source] Research Review: The relationship between childhood violence exposure and juvenile antisocial behavior: a meta-analytic reviewTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 7 2009Helen W. Wilson Background:, The connection between childhood violence exposure and antisocial behavior in adolescence has received much attention and has important implications for understanding and preventing criminal behavior. However, there are a limited number of well-designed prospective studies that can suggest a causal relationship, and little is known about the magnitude of the relationship. Methods:, This meta-analysis provides a quantitative comparison of 18 studies (N = 18,245) assessing the relationship between childhood (before age 12) violence exposure and adolescent antisocial behavior. An overall effect size (Cohen's d) was calculated for each study, an average for the 18 studies, and averages for subsets of analyses within studies. Results:, Results indicated a small effect from prospective studies (d = .31) and a large effect from cross-sectional studies (d = .88). The effect for victimization (d = .61) was larger than for witnessing violence (d = .15). Conclusions:, Effect size varied across studies employing different methodologies, populations, and conceptualizations of violence exposure and antisocial behavior. These findings do not support a simple, direct link from early violence exposure to antisocial behavior but suggest that many factors influence this relationship. [source] Predictors of parent training efficacy for child externalizing behavior problems , a meta-analytic reviewTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 1 2006Sandra M. Reyno Background:, The differential effectiveness of parent training has led researchers to examine a variety of child, parent, and familial variables that may predict treatment response. Studies have identified a diverse set of child, parent psychological/behavioral and demographic variables that are associated with treatment outcome and dropout. Method:, The parent training literature was examined to isolate child, parent, and family variables that predict response to parent training for child externalizing behavior problems. A literature review was conducted spanning articles published from 1980 to 2004 of indicated prevention (children with symptoms) and treatment (children with diagnosis) studies. Meta-analyses were conducted to determine standardized effect sizes associated with the identified predictors. Results:, Many of the predictors of treatment response examined in this meta-analysis resulted in moderate standardized effect sizes when study results were subjected to meta-analytic procedures (i.e., low education/occupation, more severe child behavior problems pretreatment, maternal psychopathology). Only low family income resulted in a large standardized effect size. Predictors of drop-out resulted in standardized effect sizes in the small or insubstantial range. Conclusions:, Response to parent training is often influenced by variables not directly involving the child, with socioeconomic status and maternal mental health being particularly salient factors. [source] Hostile Attribution of Intent and Aggressive Behavior: A Meta-AnalysisCHILD DEVELOPMENT, Issue 3 2002Bram Orobio De Castro A meta-analytic review was conducted to explain divergent findings on the relation between children's aggressive behavior and hostile attribution of intent to peers. Forty-one studies with 6,017 participants were included in the analysis. Ten studies concerned representative samples from the general population, 24 studies compared nonaggressive to extremely aggressive nonreferred samples, and 7 studies compared nonreferred samples with children referred for aggressive behavior problems. A robust significant association between hostile attribution of intent and aggressive behavior was found. Effect sizes differed considerably between studies. Larger effects were associated with more severe aggressive behavior, rejection by peers as one of the selection criteria, inclusion of 8- to-12-year-old participants, and absence of control for intelligence. Video and picture presentation of stimuli were associated with smaller effect sizes than was audio presentation. Staging of actual social interactions was associated with the largest effects. The importance of understanding moderators of effect size for theory development is stressed. [source] Reaffirmation of Behavioral Approaches to Depression TreatmentCLINICAL PSYCHOLOGY: SCIENCE AND PRACTICE, Issue 4 2009Manuel Barrera Jr This meta-analytic review improved on the methods and scope of similar reviews but reached the same conclusion that behavioral activation (BA) therapies for adult depression are much more effective than control conditions and comparable with cognitive-behavioral interventions. Future research should strengthen our understanding of the mechanisms that account for the effectiveness of BA approaches and should provide more evidence on long-term maintenance. The resurgence of interest in BA was attributed to pioneering work of Lewinsohn and the components analysis research of Jacobson and colleagues, who demonstrated the effectiveness of behavioral elements of depression treatment relative to cognitive elements. [source] Is It Time for Clinicians to Routinely Track Patient Outcome?CLINICAL PSYCHOLOGY: SCIENCE AND PRACTICE, Issue 3 2003A Meta-Analysis Empirically supported psychotherapies, treatment guidelines, best practices, and treatment manuals are methods proposed to enhance treatment outcomes in routine practice. Patient-focused research systems provide a compatible and contrasting methodology. Such systems monitor and feed back information about a patient's progress during psychotherapy for the purpose of enhancing outcomes. A meta-analytic review of three large-scale studies is summarized and suggests that formally monitoring patient progress has a significant impact on clients who show a poor initial response to treatment. Implementation of this feedback system reduced deterioration by 4% to 8% and increased positive outcomes. Our interpretation of these results suggests that it may be time for clinicians routinely and formally to monitor patient treatment response. [source] | ||||||||||||||||||||||||||||
