Self-Reported Parenting Stress and Cortisol Awakening Response Following Mindfulness-Based Stress Reduction Intervention for Parents of Children With Developmental Delays: A Pilot Study

Abstract

Background:

Many parents of children with developmental delays (DDs) experience high levels of parental stress, and young children with DDs are likely to exhibit clinical levels of behavioral problems. The reciprocal relationship between the two issues makes these families vulnerable to stress-related health risks. To address this, the current study aims to investigate the effectiveness of mindfulness-based stress reduction (MBSR) at reducing parent stress, as measured by both psychological self-report and a physiological biomarker.

Method:

A pretest–posttest design with a 6-month follow-up assessment was used to establish effectiveness with analyses of within-subject effects. Parents (N = 47) of children (2.5–5 years of age) with DDs participated in a standard 8-week MBSR intervention. Measures included the Parenting Daily Hassles, a self-report measure of perceived frequency and intensity of parenting stress, and salivary samples for measurement of the cortisol awakening response (CAR), a biological marker of stress response.

Results:

Both self-reported parenting stress and CAR decreased following MBSR for parents of children with DDs. The greatest difference in means over time was between baseline and follow-up, where changes in effect size were even stronger for biological markers than for self-report measures.

Conclusion:

The MBSR intervention reduced both perceived and physiologic stress. Health-care professionals caring for these families might consider encouraging parents to participate in MBSR as both treatment and prevention of parenting stress.
