Meta-analysis using linear mixed models

Psychologists often use special computer programs to perform meta-analysis. Until recently, this had been necessary because standard statistical packages did not provide procedures for such analysis. This paper introduces linear mixed models as a framework for meta-analysis in psychological research, using a popular general purpose statisticalpackage, SAS. The approach is illustrated with three examples, usingsas peoc mixed.

Parenting Self-Efficacy and Social Support in Japan and the United States

To understand the conditions that give rise to parenting self-efficacy in Japan and the United States, the authors have investigated its relation to the perceptions of support available to mothers of children in the final year of preschool (N = 235; n = 121 in United States, n = 114 in Japan). Hierarchical regression analysis indicates that in both countries, women who experience higher parenting self-efficacy report more positive childhood memories of parental support and greater satisfaction with husband’s and friends’ support. Mothers in the United States are significantly more self-efficacious than are mothers in Japan, even after controlling for the effects of the support predictors. A follow-up mediational analysis reveals that Japanese women’s lower levels of parenting self-efficacy are partially attributable to their low satisfaction with husband’s support.

The Effects of Marital Support, Social Network Support, and Parenting Stress on Parenting: Self-Efficacy among Mothers of Young Children in Japan.

This study investigated whether Japanese women’s perceived marital and social support affect their parenting self-efficacy directly or indirectly through their levels of parenting stress. Participants were 98 mothers of children in the second grade living in Sapporo or Osaka, Japan. Data collected through surveys were submitted to a structural equation modeling. Results showed that marital support, mothers-in-law support, and friend support each lowered women’s parenting stress, and the low stress in turn increased women’s parenting self-efficacy; however, the indirect effects of mothers-in-law support and friends support on parenting self-efficacy only approached statistical significance. The support from the women’s own mothers directly affected women’s parenting self-efficacy while the criticism from own mothers dampened women’s parenting self-efficacy indirectly by increasing their levels of stress. This study suggests that the criticism targeted to women from family and friends are detrimental to their psychological well-being, which in turn affects their parenting self-efficacy.

Explaining Local Variability in Child Care Quality: State Funding and Regulation in California.

The uneven availability of child-care centers for different kinds of families has been detailed in recent years. Much less is known about the distribution of center quality across communities. Nor do we understand the role that local contexts or state policies may play in shaping quality levels. This paper describes several quality indicators, based on reports of 170 center directors situated in three California counties. We found that most centers in lower-income and working-class communities displayed at least moderate levels of quality along structural measures, such as class size, the ratio of children per staff member, and staff education levels. About one in six failed to meet recommended quality standards. Some quality indicators were lower for centers located in communities with lower supply of center enrollment slots per capita, possibly due to excess family demand for center-based care. Center quality was not consistently influenced by community conditions such as poverty levels, ethnic composition, or maternal employment rates. Quality was higher among centers receiving stronger flows of public subsidies. We discuss the success of state agencies in advancing quality among centers and remaining policy challenges.

Parenting Self-Efficacy and Parental Involvement: Mediators or Moderators Between Socioeconomic Status and Children’s Academic Competence in Japan and Korea?

We examined the causes of a growing achievement gap associated with socioeconomic status (SES) in Korea and Japan, testing whether parenting self-efficacy (PSE) and parental involvement (PI) mediated or moderated the association of SES to children’s school-related competence (SRC). Three hundred and seventy-two Korean and 309 Japanese mothers of first- and second-grade children completed a parenting survey. Japanese mothers’ education and PSE were directly associated with SRC. PSE moderated the association of education to SRC, with higher PSE of college-educated mothers positively associated with SRC. In the Korean sample, household income was associated with SRC directly as well as indirectly through PSE.
