The cost of resilience: How allostatic load may jeopardize health through repeated demands for (successful) adaptation

Maternal alcohol dependence symptoms, maternal insensitivity to children's distress, and young children's blunted emotional reactivity

Maternal insensitivity to children's emotional distress (e.g., expressions of sadness or fearfulness) is one mechanism through which maternal alcohol dependence may increase children's risk for psychopathology. Although emotion dysregulation is consistently associated with psychopathology, it remains unclear how or why alcohol dependence's effects on caregiving responses to children's distress may impact children's emotion regulation over time, particularly in ways that may engender risks for psychopathology. This study examined longitudinal associations between lifetime maternal alcohol dependence symptoms, mothers' insensitivity to children's emotional distress cues, and children's emotional reactivity among 201 mother-child dyads (Mchild age = 2.14 years; 56% Black; 11% Latino). Structural equation modeling analyses revealed a significant mediational pathway such that maternal alcohol dependence predicted increases in mothers' insensitivity to children's emotional distress across a one-year period (β = .16, p = .013), which subsequently predicted decreases in children's emotional reactivity one year later (β = -.29, p = .009). Results suggest that mothers with alcohol dependence symptoms may struggle to sensitively respond to children's emotional distress, which may prompt children to suppress or hide their emotions as an adaptive, protective strategy. The potential developmental benefits and consequences of early, protective expressive suppression strategies are discussed via developmental psychopathology frameworks.

Cardiovascular risk and allostatic load in PTSD: The role of cumulative trauma and resilience in affected and trauma-exposed adults

BACKGROUND

The pathophysiology of posttraumatic stress disorder (PTSD) involves dysregulation of stress-sensitive biological systems due to repeated trauma exposure, predisposing individuals to the development of cardiovascular disease (CVD). Allostatic load (AL), an indicator of maladaptive stress responses, could shed light on the underlying biological mechanisms. We determined whether CVD risk and AL were associated with trauma load and resilience in women with PTSD and trauma-exposed controls (TEC).

METHODS

Adults with PTSD N = 114 and TEC N = 95 were administered the Clinician Administered Posttraumatic Stress Disorder Scale for DSM-5, to assess for current PTSD diagnosis and severity, the Life Events Checklist for DSM-5 for lifetime exposure to potentially traumatic events (cumulative trauma) and the Connor-Davidson Resilience Scale. An AL score was calculated as a sum of dichotomous variables from four physiological systems (neuroendocrine, metabolic, cardiovascular, and inflammatory). CVD risk was assessed with the South African Framingham risk score.

RESULTS

In patients with PTSD, cumulative trauma was associated with higher AL (p = 0.04) and CVD risk (p = 0.02). In TEC, AL was inversely associated with resilience (p = 0.04). There was a significant interaction between cumulative trauma and resilience on AL (p = 0.009) in PTSD cases, with a stronger association between cumulative trauma and AL in those with higher resilience.

CONCLUSIONS

Resilience may have differential detrimental and protective effects on AL in individuals with PTSD and TEC. Cumulative trauma exposure may, independently, increase the likelihood of high AL and CVD risk in PTSD, with resilience moderating this effect. Remaining resilient while experiencing PTSD symptoms may impose a biological strain that could have long-term harmful effects.

From Deficit to Strength-Based Aboriginal Health Research-Moving toward Flourishing

Aboriginal Australians have a fundamental human right to opportunities that lead to healthy and flourishing lives. While the impact of trauma on Aboriginal Australians is well-documented, a pervasive deficit narrative that focuses on problems and pathology persists in research and policy discourse. This narrative risks further exacerbating Aboriginal disadvantage through a focus on 'fixing what is wrong' with Aboriginal Australians and the internalising of these narratives by Aboriginal Australians. While a growing body of research adopts strength-based models, limited research has sought to explore Aboriginal flourishing. This conceptual paper seeks to contribute to a burgeoning paradigm shift in Aboriginal research, seeking to understand what can be learned from Aboriginal people who flourish, how we best determine this, and in what contexts this can be impactful. Within, we argue the case for a new approach to exploring Aboriginal wellbeing that integrates salutogenic, positive psychology concepts with complex systems theory to understand and promote Aboriginal wellbeing and flourishing. While deeper work may be required to establish the parameters of a strength-based, culturally aligned Aboriginal conceptualisation of positive psychology, we suggest the integration of Aboriginal and Western methodologies offers a unique and potent means of shifting the dial on seemingly intractable problems.
