This study explores the conceptualization of mother–infant cortisol attunement both theoretically and empirically, and its association with mother–infant attachment disorganization. In a community sample (N = 256), disorganization and cortisol were assessed during the Strange Situation Procedure (SSP) at infant age 17 months. Salivary cortisol was collected at baseline, and 20 and 40 min after the SSP. We utilized three statistical approaches: correlated growth modeling (probing a simultaneous conceptualization of attunement), cross-lagged modeling (probing a lagged, reciprocal conceptualization of attunement), and a multilevel model difference score analysis (to examine the pattern of discrepancies in mother–infant cortisol values). Correlated growth modeling revealed that disorganized, relative to organized, dyads had significant magnitude of change over time, such that, among disorganized dyads, as mothers had greater declines in cortisol, infants had greater increases. The difference score analysis revealed that disorganized, relative to organized, dyads had a greater divergence between maternal and infant cortisol values, such that maternal values were lower than infant values. Disorganized attachment status was not significantly associated with attunement when conceptualized as reciprocal and lagged in the cross-lagged model. Findings suggest that mother–infant dyads in disorganized attachment relationships, who are by definition behaviorally misattuned, are also misattuned in their adrenocortical responses.

This study examined infant cortisol secretion as a moderator of the association between mother–infant attachment security at age 17 months and child behavior at age 5 years. A longitudinal community sample of 96 mother–child dyads participated in the strange situation procedure (SSP) at age 17 months. Cortisol was collected at baseline, and at 20 and 40 min post‐SSP. Maternal reports of child behavior were collected at age 5 years. Results revealed that the associations between nonsecure mother–infant attachment and higher total, internalizing, and externalizing behavior were stronger for infants with high cortisol secretion, relative to infants with low cortisol secretion. The model of interaction differed depending on the outcome, with diathesis‐stress explaining variance in total as well as internalizing behavior, and with differential susceptibility explaining variance in externalizing behavior. These findings augment our understanding of risk and resilience to the impact of the early rearing environment on later psychopathology.

Background: Mindfulness and acceptance interventions (MAIs) have been identified as potentially beneficial for parents of children and adolescents diagnosed with chronic medical conditions. Objective: The objective of this review was to provide a descriptive summary of the existing literature on MAIs delivered to parents of children and adolescents diagnosed with chronic medical conditions. Data sources: Electronic searches were conducted by a Library Information Specialist familiar with the field by using EMBASE, MEDLINE, PsycINFO, EBM Reviews Databases, and Cochrane Database of Systematic Reviews. Study eligibility, participants, and interventions: Peer-reviewed journal articles of MAIs delivered to parents of children and adolescents (birth to 18 years of age) diagnosed with a chronic medical condition were eligible for inclusion. Study appraisal and synthesis methods: A total of 18 studies involving 793 parents met inclusion criteria and thus were included in this review. The majority of studies were either pre/post design (n = 8) or randomized controlled trials (n = 6). Most interventions were delivered within a group (n = 6) or individually (n = 5). Nearly all studies (n = 14) reported statistically significant outcomes following the MAI intervention. Conclusions and implications of key findings: Descriptive information yielded from this review provides promising evidence that MAIs are being delivered to parents across the world and many researchers are using similar outcome measures when assessing the psychological flexibility, acceptance, and mindfulness skills following participation in MAIs among this population of parents.
