Attachment, skin deep? Relationships between adult attachment and skin barrier recovery

Enhancing the "Broaden and Build" Cycle of Attachment Security in Adulthood: From the Laboratory to Relational Contexts and Societal Systems

Attachment theory emphasizes both the importance of the availability of caring, supportive relationship partners, beginning in infancy, for developing a sense of safety and security, and the beneficial effects of this sense of security on psychosocial functioning and physical and mental health. In this article, we briefly review basic concepts of attachment theory, focusing on the core construct of attachment security and present evidence concerning the ways in which this sense can be enhanced in adulthood. Specifically, we review findings from laboratory experiments that have momentarily enhanced the sense of attachment security and examined its effects on emotion regulation, psychological functioning, and prosocial behavior. We then review empirical findings and ideas concerning security enhancement by actual relationship partners, non-human symbolic figures, and societal systems in a wide variety of life domains, such as marital relationships, psychotherapy, education, health and medicine, leadership and management, group interactions, religion, law, and government.

The impact of stress on epidermal barrier function: an evidence-based review

BACKGROUND

The epidermal barrier functions to limit skin infection and inflammation by inhibiting irritant and immunogen invasion. Abundant evidence suggests that psychological stress stemming from crowding, isolation, nicotine smoking, insomnia, mental arithmetic tasks, physical pain, real-life stressors (examinations and marital strain) and lack of positive personality traits may impart both acute and chronic epidermal dysfunction.

OBJECTIVES

To review the relationship between stress and epidermal barrier dysfunction.

METHODS

A review of the PubMed and Embase databases was conducted to identify all English-language case-control, cross-sectional and randomized control trials that have reported the effect of stress on epidermal barrier function. The authors' conclusions are based on the available evidence from 21 studies that met the inclusion and exclusion criteria.

RESULTS

Psychological stressors upregulate the hypothalamic-pituitary-adrenal axis to stimulate local and systemic stress hormone production. This ultimately leads to aberrant barrier dysfunction, characterized by decreased epidermal lipid and structural protein production, decreased stratum corneum hydration and increased transepidermal water loss.

CONCLUSIONS

This evidence-based review explores the adverse effects of psychological stressors on epidermal barrier function. Future investigations using more real-life stressors are needed to elucidate further their impact on skin physiology and identify practical stress-relieving therapies that minimize and restore epidermal barrier dysfunction, particularly in at-risk populations. What's already known about this topic? The literature reports the negative effect of stress on prolonged wound healing. Less is known about the relationship between stress and epidermal barrier dysfunction, a chronic, superficial wound involving the upper epidermal layers. What does this study add? Psychological stressors impact epidermal barrier function by activating the hypothalamic-pituitary-adrenal axis to stimulate local and systemic stress hormone production. Stress hormones negatively affect the epidermal barrier by decreasing epidermal lipids and structural proteins, decreasing stratum corneum hydration and increasing transepidermal water loss. Identification of such stressors can promote stress-avoidance and stress-reduction behaviours that protect epidermal barrier function and prevent certain dermatological conditions.

Adult attachment and physical health

This article examines how individual differences in adult attachment shape regulatory strategies and relationship behaviors, which in turn influence health-related responses, behaviors, and outcomes. We review links between attachment and physiological responses to stress (e.g., hypothalamic-pituitary-adrenal axis responses, cardiovascular responses, immune responses), health behavior (e.g., substance use, diet), and downstream health and disease outcomes. Recent evidence suggests that attachment insecurity (attachment anxiety and/or attachment avoidance) is associated with dysregulated physiological responses to stress, risky health behaviors, susceptibility to physical illness, and poorer disease outcomes. These associations depend, in part, on the relationship context, including the other partner's attachment style and behavior. We suggest that a dyadic approach considering both partners' attachment styles and behaviors will enhance interventions to promote health.

Attachment and Health-Related Physiological Stress Processes

People who are more securely attached to close partners show health benefits, but the mechanisms underlying this link are not well specified. We focus on physiological pathways that are potential mediators of the connection between attachment in childhood and adulthood and health and disease outcomes. Growing evidence indicates that attachment insecurity (vs. security) is associated with distinctive physiological responses to stress, including responses involving the HPA, SAM and immune systems, but these responses vary with type of stressor (e.g., social/nonsocial) and contextual factors (e.g., partner's attachment style). Taking this more nuanced perspective will be important for understanding the conditions under which attachment shapes health-related physiological processes as well as downstream health and disease consequences.

Personality, relationships, and health

This special issue of the Journal of Personality focuses on the importance of considering both personality and relationship forces when examining physical and psychological health. The nine articles presented in this issue employed a variety of research designs, theoretical rationales, health outcomes, and advanced statistical methodologies in order to better understand how both individual differences and social factors are relevant to our health. These articles embody several prominent themes: Conscientiousness is a robust predictor of health; traits beyond the Five-Factor Model should be considered in attempts to understand personality, relationships, and health; links among personality, relationships, and health begin early in life; and relationship transitions are consequential to health. It is hoped that these studies inspire personality researchers to consider the relationship context of health and relationship researchers to consider individual differences when attempting to understand health behaviors and outcomes.
