Perceived stress and professional quality of life in nursing staff: how important is psychological flexibility?

Abstract

Objectives: Nurses are at high risk of chronic stress. Tailored, evidence-based stress-management interventions may minimise absenteeism and staff turnover, whilst at the same time promoting good quality patient care. Current literature for nurse-focused stress-management interventions is varied in quality, with little focus on data-driven intervention development. This study explores how process measures related to Acceptance and Commitment Training (ACT) are associated with perceived stress and professional quality of life in nurses, in order to guide intervention development.

Design: A cross-sectional, online psychometric survey was implemented using LimeSurvey software. Methods: One-hundred and forty-two nurses were recruited from various specialties across four English National Health Service (NHS) Trusts. Questionnaires assessed demographic and work-related sample characteristics, ACT processes (mindfulness, acceptance, cognitive defusion, self-as-context, values and committed action), and four work-related wellbeing outcomes (perceived stress, burnout, compassion fatigue and compassion satisfaction). Correlation and regression models were used to analyse data.

Results: All six ACT processes negatively correlated with perceived stress, burnout and compassion fatigue, and positively correlated with compassion satisfaction (all p<.05). In regression models, these same processes explained significant variance for all outcomes (R2 range=.36-.61), above and beyond that explained by socio-demographic and work-related factors. Acceptance (β range: -.25 to -.55), mindfulness (β range: -.25 to -.39), and values-based processes (β range: -.21 to -.36) were frequent independent contributors to work-related wellbeing.

Conclusions: This study demonstrates that the ACT framework provides a promising platform from which to develop nurse-focused stress-management interventions. Interventions focusing on acceptance, mindfulness, and values-linked processes may be most effective.
