Marital conflict and the quality of young children's peer play behavior: the mediating and moderating role of parent-child emotional reciprocity and attachment security.

Parent-child attachment security and dyadic measures of parent-child positive and negative emotional reciprocity were examined as possible mediators and moderators of the connection between marital conflict and children's peer play behavior. Eighty parents were observed in a laboratory play session with their 15- to 18-month-old child. Subsequently, at 36 months children were observed interacting with peers at their child care setting. Connections between marital conflict and children's positive peer interaction were mediated by mother-child attachment security, mother-child positive emotional reciprocity, and father-child negative emotional reciprocity. Connections between marital conflict and children's negative peer interaction were mediated by mother-child positive emotional reciprocity and father-child attachment security. Parent-child attachment security and negative emotional reciprocity emerged as important moderators of the connection between marital conflict and children's peer play behavior.

Coparenting, mother-infant interaction, and infant-parent attachment relationships in two-parent families.

Coparenting behavior and the quality of mothers' parenting behavior were examined in relation to parents' perceptions of their child's attachment in 60 two-parent families with 11- to 15-month-old infants (30 boys and 30 girls). Parent-child attachment was assessed using the Attachment Q-Sort. Competitive coparenting was associated with mothers' and fathers' perception of a less secure parent-child attachment relationship, whereas maternal responsiveness was associated with mothers' perception of a more secure mother-child attachment relationship. Families with mothers who were more restrictive and those with parents who were more competitive were less likely to have mothers and fathers with similar perceptions of the quality of parent-child attachment relationships. Findings support the proposal that different levels of family functioning affect the quality of parent-child relationships.

A pilot study to examine the effects of a mindfulness-based stress-reduction and relaxation program on levels of stress hormones, physical functioning, and submaximal exercise responses.

OBJECTIVE: Stress has been cited as a causal factor in heart disease. The objective of this study was to examine the effects of an 8-week mindfulness-based stress-reduction program on the resting levels of stress hormones, physical functioning, and submaximal exercise responses in women with heart disease. SUBJECTS: Random selection with the numbers 1 and 2 were used to assign 18 women (60 +/-6.3 years old) with documented histories of heart disease to a treatment group (n = 9) or a control group (n = 9). Speilberger's state anxiety scores for the treatment (M = 37.88; standard deviation (SD) = 10.91) and control group (M = 43.22; SD = 12.26) were not significantly different prior to the start of the study. However, their scores fell in the upper percentile rank for normal adults in their age category. INTERVENTION: The intervention was provided one night each week for 2 hours over a period of 8 weeks. The intervention included didactic, inductive, and experiential modes of learning regarding stress responses and mindfulness skill-development training. DESIGN: Pre-post test hormonal measurements and physical function were analyzed using a 2 (group) by 2 (time) analysis of variance (ANOVA) with repeated measures following the 8-week program. Submaximal exercise responses were also compared between the treatment group and the control group following the 8-week program. A 2 (group) by 3 (time) ANOVA with repeated measures was used to analyze the data. SETTINGS/LOCATION: Weekly meetings were held on a university medical school campus. Submaximal exercise responses were recorded while participants cycled on a stationary bike in an applied physiology laboratory following the 8-week program. RESULTS: There were no significant main effects or interaction for the resting levels of stress hormones or physical functioning. There were no significant interactions for the submaximal exercise responses, however, there were significant main effects between groups for ventilation [F(2,32) = 7.65, p < .01, f = 0.8], and between group [F(1,16) = 8.84, p < .01, f = 0.8] and time [F(2,32) = 10.42, p < .01, f = 0.9], for breathing frequency. CONCLUSION: While the 8-week stress reduction program for women with heart disease did not show significant interactions between groups for resting levels of stress hormones, physical functioning, or submaximal exercise responses, there was a significant difference in breathing patterns between the 2 groups during exercise following the mindfulness-based stress-reduction program. There was also a trend for change in the intervention group in the resting levels of cortisol and physical function scores that was not seen in the control group. Future studies could use the effect size generated from this pilot study to calculate the number of subjects needed for adequate power to detect significant differences between groups.

Mindfulness meditation, anxiety reduction, and heart disease: a pilot study.

Heart disease is the leading cause of death among Americans each year, yet the misperception still exists that cardiovascular disease is not a serious health problem for women. Evidence indicates that anxiety contributes to the development of heart disease. The primary purpose of this study was to assess the effectiveness of Kabat-Zinn's mindfulness-based stress reduction program to reduce anxiety in women with heart disease. Anxiety, emotional control, coping styles, and health locus of control were compared in a treatment and control group of women with heart disease. Post-intervention analyses provide initial support for beneficial effects of this program.
