Job satisfaction: a meta-analysis of stabilities

JOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 5 2001
Christian Dormann
Evidence suggesting that job satisfaction is caused by individual dispositions is reviewed, and stability coefficients for job satisfaction in previous studies are analysed with a meta-analytic procedure. Previous longitudinal studies analysing job changer samples imply an upper limit estimate of 0.51 for direct dispositional influences on job satisfaction. A study of job changers considering the stability of working conditions suggests that this estimate has to be considerably corrected downwards. At present, it is concluded that it is more likely that dispositions indirectly affect job satisfaction via selection and self-selection processes. Implications for job satisfaction as a tool for organizational assessment are discussed. Copyright 2001 John Wiley & Sons, Ltd. [source]


A meta-analysis of serotonin metabolite 5-HIAA and antisocial behavior

AGGRESSIVE BEHAVIOR, Issue 4 2002
Todd M. Moore
Abstract During the past 25 years, researchers have examined the relationship between neurochemical variables and antisocial behavior in human adults, but none has been studied more intensely than the serotonin metabolite 5-hydroxyindoleacetic acid (5-HIAA). The goal of the current study was to employ meta-analytic procedures to quantitatively evaluate selected evidence on the relationship between 5-HIAA and antisocial behavior. It was expected that antisocial groups would show reduced cerebrospinal fluid 5-HIAA compared with non,antisocial groups. This study also aimed to assess moderators that could influence the relationship between 5-HIAA and antisociality. An electronic search and strict inclusion criteria identified 20 reports used in this meta-analysis. Results showed a significant overall mean effect size (ES = ,.45, P < .05) in the direction of lowered 5-HIAA in antisocial vs. non,antisocial groups. A significant moderating effect for age indicated that groups comprised of antisocial individuals younger than 30 years exhibited larger negative effect sizes (ES = ,1.37, P < .05) than groups with older subjects (ES = ,.31, P < .05). There were no moderating effects for gender, target of violence, history of suicide, and alcoholism. Age effects may help explain age-related declines in crime. The fact that effects did not differ based on other moderating variables supports models of reduced serotonin in antisocial individuals, regardless of type of crime or psychiatric problems. Aggr.

Relationships between psychological climate perceptions and work outcomes: a meta-analytic review

JOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 4 2003
Christopher 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.

Predictors of parent training efficacy for child externalizing behavior problems , a meta-analytic review

THE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 1 2006
Sandra 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.
