Clinically depressed and typically developing mother–infant dyads: Domain base rates and correspondences,relationship contingencies and attunement

Maternal depression is associated with adverse outcomes in infants. Unfavorable parenting practices likely constitute one pathway of risk transmission from mother to infant, but definitional and methodological variation in the extant literature precludes a comprehensive or conclusive understanding of potential underlying mechanisms. This study aimed to illuminate the role of maternal clinical depression in mother–infant interaction by turning a microanalytic lens on four substantive relationship issues: base rates, correspondences, contingencies, and attunement. Several maternal parenting practices (aggregated into social, didactic, and language domains) and several infant behaviors (aggregated into social, exploration, and non-distress vocalization domains) were microcoded to 0.10 s from naturalistic hour long interactions of clinically depressed mothers (n = 60) and matched non-depressed controls (n = 60) with their 5-month-olds. Clinically depressed mothers spontaneously engaged their infants less didactically, were less contingent to their infants in social, didactic, and language domains, and were less attuned with their infants than were non-depressed mothers. Infants of clinically depressed mothers vocalized non-distress less than infants of non-depressed mothers. These differences unveil key disadvantages in the everyday lived experiences of infants of clinically depressed mothers. The findings advance understanding of maternal depression and its effects and have implications for identifying infants at risk on account of their mothers’ clinical depression.     

Relationship between attendance at a parents anonymous adult program and children's behavior at the parents anonymous child care program

The purpose of this research was to determine the statistical relationship between the proportion of parent group meetings attended by parents who were involved in a Parents Anonymous Adult Program and the number of positive behavioral ratings received by children who attended the Parents Anonymous Child Care Program. The research hypothesis was that parents who attend a higher proportion of the parent group meetings are more likely to have children who receive positive behavioral ratings during the Child Care Program. A two-way analysis of covariance indicated the main effect of attendance was significant, p < .0009.

Needed services for foster parents of sexually abused children

Foster parents with little preparation and short notices must often deal with severe emotional and behavioral difficulties of sexually abused children. This article reports on a survey of the services provided to foster parents who care for sexually abused children in a large city in the Northeast United States. Agency directors, social workers and foster parents were asked to respond to mailed questionnaires. The results indicated that foster parents consistently reported that they received less extensive educational and support services than were reported by social workers and directors of foster care agencies. All groups recommend further expansion of training programs for foster parents of sexually abused children.This paper was presented at the Temple University Chapter, Phi Delta Kappa, Philadelphia, PA, April 5, 1990.Ms. Egan is a Research Assistant; Ms. Cossett and Ms. Auletta were studients from Smith College School for Social Work.
