Two surveys 13 years apart (2002 and 2015) using identical questionnaires collected data on crew from a Norwegian ship owner. The survey used reliability tested scales and items from previous research measuring 12 different factors: 1) Satisfaction with safety activities, 2) Management control, 3) Fatalism, 4) Knowledge/competence, 5) Conflict between work and safety, 6) Reporting culture, 7) Communications, 8) Management attitude towards safety, 9) Positive management behaviour, 10) Job satisfaction, 11) Attitudes towards safety rules and 12) Learning culture were linked to four different dependent behavioural scales (outcome variables) used in previous research: 1) Positive management behaviour, 2) Precautionary behaviour, 3) Laissez-faire behaviour and 4) Laissez-faire behaviour under pressure. Significant positive changes between 2002 and 2015 appeared for factor 1, 2, 4, 5, 6, 7, 9, 10 and 12, a significant negative change were found for factor 3 and no significant change were found for factor 8 and 11.
