Adult attachment insecurity and responses to prolonged severe occupational stress in hospital workers during the COVID-19 pandemic

Background: The stress response includes appraisal of the threat and one's resources, coping (including interpersonal interactions), distress, and recovery. Relationships between patterns of adult attachment and stress response have received little study in the context of prolonged, severe occupational stress, limiting knowledge about how attachment patterns contribute to occupational burnout and recovery. Aim: This study aimed to assess the relationship of adult attachment to aspects of the stress response over time in hospital workers during a pandemic. Methods: This study included 538 hospital workers within a general and a rehabilitation hospital in Toronto, Canada between September 2020 and November 2021. Half, selected at random, completed validated measures of adult attachment, resilience, self-efficacy, coping, interpersonal problems, and various stress outcomes. Attachment insecurity severity was calculated as the vector addition of attachment anxiety and attachment avoidance. Correlations between these measures were determined at individual time-points and temporal patterns of adverse outcomes using repeated-measures ANOVA. Results: All correlations between measures of attachment and resilience or self-efficacy were significant and moderately strong (r =30-.48), while most correlations with coping strategies were weak (<.20). Attachment avoidance was more strongly correlated with interpersonal problems related to being cold, whereas attachment anxiety was more strongly correlated with problems related to being intrusive, overly-nurturant, exploitable and non-assertive. Attachment insecurity severity was moderately correlated with every dimension of interpersonal problems. A significant main effect of each attachment measure on each stress outcome was found (effects sizes: .18-.26). Attachment insecurity severity was significantly associated with outcome X time interactions for burnout, consistent with greater resilience for those with lower attachment insecurity. Conclusions: Severity of insecure attachment was correlated with each measure of self-appraisal, interpersonal problems, and all measured stress outcomes. Severity of attachment insecurity performed well as a summary attachment measure. Greater security is associated with patterns of recovery that indicate resilience.
