Purpose – The purpose of this paper is to develop and validate a measure of job insecurity climate by: first, testing whether job insecurity climate and individual job insecurity are two separate constructs; and second, investigating the relative importance of individual job insecurity and job insecurity climate in predicting work-related and health-related outcomes. Design/methodology/approach – Data were collected by questionnaires in a simple stratified random sample of 1,380 white-collar workers in Sweden. The response rate was 56 percent. Findings – Confirmatory factor analyses showed that job insecurity climate was distinct from individual job insecurity. Four separate ridge regression analyses showed that qualitative job insecurity climate was a significant predictor of demands, work-family conflict, psychological distress, and poor self-rated health and that quantitative job insecurity climate predicted demands and work-family conflict. Research limitations/implications – The study is based on self-reports, which may involve common method bias. The cross-sectional study design limits the possibility to make causal inferences regarding the relationship between job insecurity climate and outcomes. Practical implications – Future studies may consider measuring job insecurity climate in line with a referent-shift model. Work environment surveys in organizations that include measures of individual job insecurity and job insecurity climate can provide practitioners with a fuller picture of the psychosocial work environment. Originality/value – The present study adds to previous research by introducing a new approach to measuring and conceptualizing job insecurity climate.
