Improving Causal Inferences in Meta-analyses of Longitudinal Studies: Spanking as an Illustration.

To evaluate and improve the validity of causal inferences from meta-analyses of longitudinal studies, two adjustments for Time-1 outcome scores and a temporally backwards test are demonstrated. Causal inferences would be supported by robust results across both adjustment methods, distinct from results run backwards. A systematic strategy for evaluating potential confounds is also introduced. The methods are illustrated by assessing the impact of spanking on subsequent externalizing problems (child age: 18 months to 11 years). Significant results indicated a small risk or a small benefit of spanking, depending on the adjustment method. These meta-analytic methods are applicable for research on alternatives to spanking and other developmental science topics. The underlying principles can also improve causal inferences in individual studies.

Associations between parenting style, physical discipline, and adjustment in adolescents' reports.

Recollections of physical discipline as absent, age-delimited (ages 2-11), or present into adolescence were associated with youths' evaluations of their mothers' and fathers' parenting styles and their own adjustment. Data were from the Portraits of American Life Study-Youth (PALS-Y) a diverse, national sample of 13- to 18-year-olds (N = 158). The modal experience of youth with authoritative parents was age-delimited spanking; the modal experience of youth with permissive parents was no spanking; the modal experience of youth with authoritarian or disengaged parents was physical discipline into adolescence. The age-delimited group reported the best adjustment (less maladjustment than the adolescent group; greater competence than both other groups). The positive association between fathers' age-delimited spanking and youths' academic rank persisted even after accounting for parenting styles. The eschewing of spanking should not be listed as a distinguishing characteristic of authoritative parenting, which was more often associated with age-delimited spanking than with zero-usage.

The insufficiency of the evidence used to categorically oppose spanking and its implications for families and psychological science: Comment on Gershoff et al. (2018).

Gershoff et al. (2018) recently summarized the scientific evidence against disciplinary spanking, using epidemiological and psychological criteria for causal validity. Unfortunately, the evidence they cited would make most actions to correct serious problems appear to be harmful, whether implemented by parents (e.g., timeout) or professionals. The reason is that the type of evidence that Gershoff et al. consider adequate is insufficient for establishing a causal connection between any disciplinary response to persistent defiance and problem behaviors in children, whether that response is spanking or an effective alternative to spanking. Before opposing a widespread practice such as spanking, researchers need to document stronger causal evidence against it and identify an alternative demonstrated to be more effective.

Differential impact of fathers' authoritarian parenting on early adolescent adjustment in conservative protestant versus other families.

The purpose of the study was to determine whether well-established associations between authoritarian parenting and adolescent adjustment pertain to conservative Protestant (CP) families. Structural equation modeling was used to test paths from biological fathers' authoritarian parenting to adolescent adjustment in 65 CP versus 170 comparison families in the Nonshared Environment and Adolescent Development Study (NEAD; D. Reiss et al., 1994). The hypothesis that adolescents in CP families would be less harmed by authoritarian parenting than would adolescents in control families was partially supported: Authoritarian parenting directly predicted greater externalizing and internalizing for adolescents in control families but not for adolescents in CP families. In contrast, parents' religious affiliation failed to moderate the negative associations between authoritarian parenting and positive adjustment. Understanding family processes specific to the CP subculture is important for helping these families raise competent children.

Stepchildren's perceptions of noncustodial mothers and noncustodial fathers: differences in socioemotional involvement and associations with adolescent adjustment problems.

Caucasian stepchildren (aged 10-18) in the Nonshared Environment and Adolescent Development (NEAD) project rated noncustodial (NC) parents' socioemotional involvement. Stepfamilies had been together at least 5 years. Adolescents with NC mothers (n = 56) reported more phone calls, mail, overnight visits, and social support than adolescents with NC fathers (n = 143). The association between perceived social support and adolescent adjustment was compared for NC mothers versus NC fathers by using structural equation modeling; the association was stronger for NC mothers. No effects for sex of child or interactions of sex of child/sex of NC parent were obtained. NC fathers might increase their influence in adolescents' lives by behaving more like NC mothers (more frequent phone calls, overnights, etc.).
