Psychosocial safety climate and supportive leadership as vital enhancers of personal hope and resilience during the COVID-19 pandemic.

This study aimed to investigate the effects of supportive leadership and psychosocial safety climate on personal hope and resilience among nurses during the pandemic. Conservation of resource theory was employed to explain the effects of psychosocial safety climate and supportive leadership on nurses' hope and resilience. A cross-sectional design was employed to collect data. Six-hundred and twenty-three nurses across 68 hospitals who were in direct contact with COVID-19 patients during the fifth wave of the pandemic in Iran were recruited. Hierarchical Linear Modelling (HLM) and Structural Equation Modelling using Amos were used to analyze the data. Results revealed that both psychosocial safety climate and supportive leadership improved personal resilience through personal hope. Findings showed that the positive relationship between supportive leadership and personal hope was stronger when the hospital-level psychosocial safety climate was high. To improve personal hope and resilience among nurses during critical times, hospital management must ensure consistent supportive leadership and establish policies, practices and procedures that support nurses' psychosocial health and safety at the hospital level.
