Association between 'Psychological Capital' and 'Safety Climate' among Norwegian air traffic controllers

'Psychological Capital' and 'Safety Climate'

Bergheim et al (20131) carried out research to ascertain the association between air traffic controllers' psychological resources (efficacy, optimism, hope and resilience) and perceived commitment to safety (by colleagues and by managers) in their organizations. The psychological resources measures were grouped into a construct called 'Psychological Capital', and the perceived safety commitments were grouped into a construct called 'Safety Climate'.

Illustration 1 summarizes the relevant results. At bivariate levels, there was a moderate positive correlation between 'Psychological Capital' and 'Safety climate' (r = 0.52). A subsequent regression analysis on 'Safety climate' as criterion, using 'Psychological Capital', gender and age as predictors, resulted in a similar multiple correlation coefficient (R = 0.56), with 'Psychological Capital' having a large positive correlation (β = 0.80) and gender a small correlation in favor of females (β = -0.31).
