Criterion-related validity of the cultural web when assessing safety culture

The overall safety culture was shared and stable. Cronbach's Alpha (0.845) indicated reliability. Criterion-related validity between the organisation's Total Recordable Incident Rates (TRIR) for the cultural web topics (r = 0.488, p < 0.01) and specific safety culture topics (r = 0.417, p < 0.01) was found. Multiple regressions against specific incident records returned adjusted R2 criterion-related validity coefficients between 0.06 and 0.45. Both perspectives confirmed the criterion-related validity of the cultural web tool, albeit stronger relationships tended to be obtained from the safety culture topics. The study results reinforce the conclusion that the tool is a reliable and valid method that can help companies reduce organisational and occupational incidents and improve their safety culture.
