Tactile/kinesthetic stimulation effects on preterm neonates.

Tactile/kinesthetic stimulation was given to 20 preterm neonates (mean gestational age, 31 weeks; mean birth weight, 1,280 g; mean time in neonatal intensive care unit, 20 days) during transitional ("grower") nursery care, and their growth, sleep-wake behavior, and Brazelton scale performance was compared with a group of 20 control neonates. The tactile/kinesthetic stimulation consisted of body stroking and passive movements of the limbs for three, 15-minute periods per day for a 10 days. The stimulated neonates averaged a 47% greater weight gain per day (mean 25 g v 17 g), were more active and alert during sleep/wake behavior observations, and showed more mature habituation, orientation, motor, and range of state behavior on the Brazelton scale than control infants. Finally, their hospital stay was 6 days shorter, yielding a cost savings of approximately $3,000 per infant. These data suggest that tactile/kinesthetic stimulation may be a cost effective way of facilitating growth and behavioral organization even in very small preterm neonates.

Hospitalization stress in children: sensitizer and repressor coping styles.

To examine the effects of individual sensitizer/repressor coping styles on responses to hospital procedures, 56 children (mean age = 6.5 years) were observed during hospitalization for minor surgery. Although the sensitizer children, as classified by their mothers, did not differ from the repressor children on baseline measures including hospital preparation, they were more talkative, expressive, and active during hospital play observations. During blood tests and preoperative injections, the sensitizers, compared with the repressors, were reported by their mothers to observe the procedures, to seek additional information about the procedures, and to show more protest behaviors. Finally, the sensitizer children required fewer hours of intensive care.

Type A behavior in preschool children.

Type A behaviors were observed in a group of 48 preschool children in different free-play and competitive situations. Interrater reliability was assessed on the Matthews Youth Test for Health (MYTH), and the children's and their parents' type A scores were compared. Scores on the MYTH were used to classify children as either type A or type B. Comparisons were made between type A and type B children's play in classroom and in laboratory situations. For the laboratory situations, 24 same-sex type A-type B dyads were formed, and the dyads were observed in free play, followed by car racing, by a tower-building contest, and by an interview. Type A children more frequently showed annoyed facial expressions, gross motor activity, interruptions during classroom free play, and gross motor activity and aggressive play with an inflatable Bobo doll during the laboratory free-play situation. Type A children more often won the car race and the tower-building contest, and they answered a greater number of questions and more frequently answered first during the interviews. These data are consistent with other findings on type A behavior in preschool children and suggest that the behavioral dimensions of type A (competitiveness and impatience-aggression) may emerge as early as the preschool years, particularly in competitive situations.
