Social support and child maltreatment: a review of the evidence.

Parents who maltreat their children have long been thought to lack support from informal and social networks. Recent writers have taken the position that this relationship is a proven, causal one, with social isolation seen as a necessary antecedent condition for the occurrence of child abuse. Concurrently, initial enthusiasm for social support as a powerful explanatory variable in other areas of psychological and health research is giving way to cautious reevaluation of the evidence. The present review was undertaken to bring into sharper focus what is now known regarding the relationship between child maltreatment and parental isolation from informal helping networks. Existing research is fraught with both conceptual and methodological problems. There is, at present, little research evidence that lack of social support plays a significant role in the etiology of physical abuse. Stronger evidence exists that neglectful parents are socially isolated, but the data are consistent with the hypothesis that this is one manifestation of the character problems of these parents. Future research must give closer attention to clearly defining social support and using reliable and valid instruments to measure it, while exploring multivariate models of child maltreatment.

Neglected and abused children of mentally retarded parents.

Sixty-four neglected and abused children with a mentally retarded parent seen from one to seven years earlier, were followed to determine placement outcomes. At the time of follow-up, 11 of 64 children remained with their low functioning parents. Six children had been relinquished voluntarily for adoption and courts had terminated parental rights for 34, resulting in a total of 40 who had been adopted. Nine children were in foster care at the time of the study; two had been awarded to their nonretarded parent following divorce; and two had died. All families had received public financial assistance and medical care and used an average of 10 other services per family. Because of their cognitive limitations, most of these retarded parents were unable to benefit sufficiently from community services to enable them to care for their children. These findings point up the need for a mechanism whereby the retarded adult's right to parent and the child's right to nurturance and protection may both be preserved. Until this dilemma can be resolved, decisions to terminate parental rights in such cases should be made more quickly.

Developmental abilities of children exposed to polybrominated biphenyls (PBB).

To investigate whether ingestion of polybrominated biphenyls has an adverse effect on the neuropsychological development of young children exposed in utero and in infancy, five tests of the McCarthy Scales of Children's Abilities were administered to a group of 19 PBB-exposed Michigan children. When the data for the exposed group were analyzed according to body burden of PBB as determined by fat biopsy, correlations ranging from -.5228 to -.3004 were found between the natural logarithms of the children's fat PBB values and their standardized scores on the developmental scales. Four of the five correlations were significant at p less than .05. Multivariate analysis of covariance confirmed the existence of a significant main effect for fat PBB level, with parental education held constant. Children with higher body burdens of PBB (greater than .100 ppm) scored significantly lower than exposed children with lower body burdens on the same four tests, and on a composite score representing overall performance. These results suggest the existence of an inverse relationship between body levels of PBB and some developmental abilities in young children.

The effect of polybrominated biphenyl on infants and young children.

The effects of PBB on 33 children born between September 1, 1973, and December 31, 1975, were evaluated in September, 1977. These children, born to families who lived on quarantined farms, were compared to 20 children who were not exposed to PBB. The birthdate interval was selected to obtain children who were exposed in utero or in early infancy or both, the two time periods when damage to developing tissues and organ systems should have been maximal. The results of these studies failed to identify any effects on physical growth, physical examination, or neurologic assessment, although the parents indicated by historical review that the exposed children had had more illnesses, especially respiratory, than had the control children. There were some indications of an inverse relationship between PBB fast level and performance on selected developmental tests.
