Individual differences in response to stress

Observation of newborns and infants reveals individual differences in reactivity to stress. A measurement system based on threshold, dampening, and reactivation is described to assess these individual differences in the newborn period and thereafter. The three features are independent and, therefore, represent different aspects of reactivity. There is some evidence for stability of individual differences in reactivity between birth and 2 months of age. This stability is more apparent for infants who were highly reactive as newborns. The role of dispositional factors of reactivity, their stability, and the effects of the environment are discussed.

Communication deficits in childhood schizotypal personality disorder

This study examined the similarities and differences in the communication deficits of 13 schizotypal and 12 schizophrenic children matched by age and IQ. Like schizophrenic children, schizotypal children underutilize some discourse devices necessary for coherent speech and overutilize others. Schizotypal children, however, appear to display a more restricted range of discourse deficits than schizophrenic children. In addition, their discourse deficits do not appear to be associated with clinical measures of loose associations. The clinical implications and the potential use of discourse measures to differentiate schizophrenic and schizotypal children are discussed.

Relationships between parental ratings of infant temperament, risk status, and delivery method

One hundred forty parents rated the temperament of their infants between the ages of 4 and 8 months. Analyses of the data examined the relationships between temperament and infant risk status (high or low), delivery method (vaginal or cesarean section), and the combined effects of infant risk status and delivery method. Although high-risk and low-risk infants were similar on the easy-difficult profile ratings of the revised infant temperament questionnaire, high-risk infants were rated more adaptable and more positive in mood than were the low-risk infants. Low-risk infants delivered by cesarean section were rated less optimally on three of the temperament factor scores, including withdrawal, mood, and adaptability. Interpretations of these findings are discussed and suggestions are offered for nurse practitioners and their provision of pediatric care to infants and their families.

The challenge of transferring responsibility for diabetes management from parent to child

To emancipate from their parents, children and adolescents with diabetes eventually must assume responsibility for self-care. The challenge that parents and health care professionals face is deciding when and how to transfer this responsibility from parent to child. Inappropriate transfer of self-care responsibility can precipitate poor metabolic control and strain parent-child relationships. By planning the gradual transfer of this responsibility based on children's cognitive abilities, maturity level, demonstrated self-care skills, and family environment factors, health care providers can minimize these problems.

Temperament and the psychobiology of childhood stress

This paper provides a conceptual overview of recent research on the developmental psychobiology of childhood stress. We propose that the construct of temperament can be regarded as an organizing principle in children's responses to environmental adversity, and we review three physiologic "windows" through which such responses can be usefully examined. It is concluded that individual differences between children in their psychobiologic reactivity to stressors may constitute an important and novel point of departure for future studies of stress and childhood morbidity.

Interviews with children who experienced major life stress: family and child attributes that predict resilient outcomes

Demographically comparable groups of children exposed to major life-stress, with stress resilient (SR) and stress affected (SA) outcomes at ages 10 to 12, were interviewed to assess perceptions of their caregiving environments, peer relationships, and themselves. SR children compared with SA children reported more: (1) positive relationships with primary caregivers, (2) stable family environments, (3) inductive and consistent family discipline practices, and (4) positive expectations for their futures. SR girls viewed their mothers as more nurturing than did SA girls. Perceptions of fathers, quality of peer relationships, and global self-concept did not differentiate the groups. A discriminant function analysis identified four variables that correctly classified 74% of the subjects as SR or SA. Findings support the view that caregiver-child relationships play a key role in moderating children's developmental outcomes under conditions of high stress.

Intervention program for obese school children

The purpose of this study was to implement and evaluate a program for obese school children. A pretest-posttest design was utilized. Data was collected related to weight status, skinfold measurements, self-esteem, and nutritional knowledge. A convenience sample of 26 children, in the fourth to sixth grades, completed this 9-week program. The results indicate that self-esteem increased significantly (p less than .001) between the pretest and posttest interval. Weight status and nutritional knowledge showed no improvement. Exercise was difficult to assess on self-report, therefore no conclusions were were drawn in relation to this variable. Future research will be directed toward refining this intervention program.

Body image of children and adolescents and its measurement: an overview

The lack of a universally accepted definition of body image has impeded our understanding of body image disturbances in children and adolescents. This paper examines the evolution of body image as a multidimensional construct and the difficulties associated with the use of human figure drawing to measure body image. Directions for future research are considered.

The perception of identity by 6 1/2-month-old infants

In Study 1, sixteen 6 1/2-month-olds were habituated to a Reversible stimulus (an upright face that could be perceived as an entirely different upright face when it was rotated 180 degrees) and to a Nonreversible stimulus (a face that could be perceived as upright in only one orientation). Following habituation for each type of stimulus, test trials paired the habituated face with a novel stimulus (an inversion of the same face). For both Reversible and Nonreversible stimuli, the physical difference between the old and new test stimuli was the same (a 180 degrees rotation); however, infants devoted more visual attention to the 180 degrees rotation only when it was a Reversible face, suggesting that the identity change was detected. Experiment 2 ruled out the explanation that infants might have failed to dishabituate to the inversion of the Nonreversible stimulus because they could not remember it. Results are interpreted as evidence that 6 1/2-month-old infants are not limited to face recognition based on similarity in pattern arrangement alone, but are capable of processing faces at a representational level.

Intermodal perception of happy and angry expressive behaviors by seven-month-old infants

2 studies were conducted to examine the roles of facial motion and temporal correspondences in the intermodal perception of happy and angry expressive events. 7-month-old infants saw 2 video facial expressions and heard a single vocal expression characteristic of one of the facial expressions. Infants saw either a normally lighted face (fully illuminated condition) or a moving dot display of a face (point light condition). In Study 1, one woman expressed the affects vocally, another woman expressed the affects facially, and what they said also differed. Infants in the point light condition showed a reliable preference for the affectively concordant displays, while infants in the fully illuminated condition showed no preference for the affectively concordant display. In a second study, the visual and vocal displays were produced by a single individual on one occasion and were presented to infants 5 sec out of synchrony. Infants in both conditions looked longer at the affectively concordant displays. The results of the 2 studies indicate that infants can discriminate happy and angry affective expressions on the basis of motion information, and that the temporal correspondences unifying these affective events may be affect-specific rhythms.

Children's venipuncture pain: influence of technical factors

Several aspects of venipuncture technique were evaluated to assess their relationship to reported pain. Subjects were 514 children aged 5-17 who had venipuncture performed by a technician in a hospital outpatient laboratory. A research assistant timed the duration of venipuncture and then obtained visual analogue pain scores from the children following venipuncture. Blood volume obtained from venipuncture was also measured. The technician who performed the procedure, amount of blood drawn, and time required to complete the venipuncture did not contribute to the prediction of children's pain. Age and anxiety, which were treated as covariates, were significant predictors of pain. The distribution of pain experienced by children was positively skewed and about one-third of children were above the mean pain score. From the results of this study, venipuncture pain can be recommended for the study of issues in children's pain. Further, the findings recommend the development and utilization of interventions to reduce children's venipuncture pain.

Causes of child abuse and neglect

This paper is a study of child abuse and neglect from the perspective of the child. Generally, the mistreatment of children was associated with "poor care" from parents, attributed mainly to immaturity, marital problems, alcohol abuse, unemployment, drug abuse and lack of money. Differences in attribution are noted between males and females, and some differences are noted by the age of the child. When factors other than the causes given by the children were taken into account, mistreatment was significantly related to family break-up, as well as long-term disinterest and lack of affection from the parents. When the children were asked for their "worst experience in life," the most common responses were "abuse" "family break-up," and for the juvenile offenders "getting charged with a crime."

Perceptions of acquired immune deficiency syndrome by children and their parents

Assessed perceptions of acquired immune deficiency syndrome in school-aged children and their parents. Using a hierarchical regression analysis, parent attitudes toward AIDS were found to be significant predictors of a child's attitudes toward persons with AIDS, but were not significant predictors of a child's knowledge of AIDS. The child's own knowledge level served as a significant predictor of the child's attitudes and vice versa.

Parental perception of the effect of venepuncture in preschool children in non-therapeutic research

Non-therapeutic research in children is said to be justified in part if the risk involved is no more than minimal, but there is little information on the risk of venepuncture to make that judgement. This prospective study was carried out to assess the effect of venepuncture on 425 healthy children aged between 3.6 and 6.6 years old who participated in a non-therapeutic research project. A parental questionnaire was sent out 1 month after the blood was taken. Three hundred and ninety-one parents (92%) returned the questionnaires. Parental responses indicated the risk of complications was of the order considered to be minimal. A large majority of parents (78%) felt this experience would be helpful for the child if blood had to be taken again and a significant proportion (40%) felt the child would be more confident when going to see a doctor or dentist afterwards. Venepuncture in preschool children causes minimal harm and might even have some positive effects.

Children's knowledge of internal anatomy: conceptual orientation and review of research

Children's understanding of health and illness is influenced by their knowledge of internal anatomy and physiological functioning. This article provides a comprehensive review of studies of children's knowledge of internal anatomy, one component of internal body image. Consistencies, controversies, and methodological issues that emerge across the studies are discussed. A conceptual framework for the development of children's internal body image is presented. The framework posits relationships between cognitive development, health status, knowledge of internal body image, and understanding of physiological functioning. Future studies are needed to test and refine the conceptual framework and to develop interventions to facilitate children's internal body image.
