In several recent reports, the Carey Infant Temperament Questionnaire has been criticized as a measure of infant temperament. Instead, the dimensions of temperament and the diagnostic categories (i.e., "easy" vs. "difficult" temperament) derived from maternal responses to the questionnaire items have been associated with maternal demographic and personality characteristics and with maternal child-rearing attitudes assessed before the birth of the infant. In this article, results of previous research are reconsidered in light of suggestions and criticisms offered by several temperament researchers. In two new studies the revision of the Infant Temperament Questionnaire (ITQ) was used to assess infant temperament, and personality and/or attitudinal data from the mother were obtained prenatally. Results were consistent across all studies. Prenatally assessed characteristics of the mother, especially anxiety, significantly distinguish mothers whose responses to the ITQ items result in diagnosis of temperamental difficulty for their infants from those whose infants are diagnosed as temperamentally easy during the first 8 months of life. The data suggest that both the original and revised Carey infant temperament scales fail discriminant validity tests and are therefore of only limited use in identifying temperamentally difficult infants.The notion that individual differences in temperament or behavioral style account for significant proportions of the variation in responsiveness to day-to-day life events has been commonplace for many years. Though the endogenous and/or experiential origins of temperament have never been clearly
Recent reports have suggested that day-care experience initiated prior to 12 months of age is associated with increased proportions of infants whose attachment to mother is classified as "insecure-avoidant." However, reviewers have questioned the generality of these findings, noting that samples in which associations between early day-care experience and avoidant attachment patterns have been reported come from high-risk populations, and/or that the infants' day-care settings may not have been of high quality. In the present study, effects of maternal absences on infant-mother attachment quality were assessed in a low-risk, middle-class sample (N = 110). In all instances, substitute care had been initiated at least 4 months prior to the infant's first birthday and was provided in the infant's home by a person unrelated to the baby. Infants were assessed using the Ainsworth Strange Situation when they were 12-13 months of age. Analyses indicated that a significantly greater proportion of infants whose mothers worked outside the home (N = 54) were assigned to the category "insecure-avoidant" as compared to infants whose mothers remained in the home (N = 56) throughout the first year of life. Analyses of demographic and psychological data available for the sample indicated that this relation is dependent upon maternal parity (primi- vs. multiparous mother). The association between attachment quality and work status was significant only for firstborn children of full-time working mothers. The results are interpreted as evidence that the repeated daily separations experienced by infants whose mothers are working full-time constitute a "risk" factor for the development of "insecure-avoidant" infant-mother attachments.
Psychosomatic research findings correlating psychologic stress with diabetic control fail as yet to provide valid conclusions. Investigators have presented many contradictory findings. The two major pathways by which stress could affect control, a) changes in compliance behavior, and b) a neurohumoral axis, have not been clearly distinguished from each other. The study of adolescent cohorts is associated with the problem of heterogeneity, limiting the application of results to other diabetic populations. Methods of determining diabetic control have been incomplete and the definition and measurement of stress have major inadequacies for the analysis of such a complex psychosomatic problem. Existing evidence is comprehensively reviewed and evaluated. The authors use a modified definition of stress to construct a stress scale specific to pregnant diabetics.
In summary reviews and empirical research, investigators have suggested that attachment classifications derived from the Ainsworth Strange Situation may reflect variations along dimensions of temperament as well as, or perhaps instead of, individual differences with respect to infant-mother attachments. In this study, relations between temperament dimensions from the Infant Temperament Questionnaire (Revised) and Strange Situation behaviors were evaluated. Relations between the behavioral style scores and the categories of attachment quality were also tested. The hypothesis that temperamental difficulty would be related to negative emotionality, as indexed by infant distress during separation (but not during the reunions), was tested and supported. Neither the behavioral style dimensions nor the temperamental diagnoses (e.g., "easy" vs. "difficult") were associated significantly with attachment classifications. The results are consistent with previous findings that temperament measures do not predict attachment security. Nevertheless, certain behaviors indexing negative emotionality that may be observed in the context of the Strange Situation are related to temperamental variability.
