Moral responsibility was measured using a scale developed by Hart [22]. Three dimensions of moral responsibility were included (see Table 1 for the themes). The mean was used as total score on moral responsibility. The Cronbach alpha for this scale was 0.60.
Data analysis
To investigate the current status of the implementation of HP interventions (aim 1), percentages were given of the currently implemented HP themes and actions. Chi2-test were used to analyze if these results differed by the characteristics of the workshop.
To investigate which characteristics of the workshop and individual factors of the respondent were related to the implementation of environmental HP (aim 2) and to being supportive towards implementing HP in the future (aim 3), univariate logistic regressions were used. A multivariate logistic regression was performed with all significant factors from the univariate analyses.
SPSS 21 was used to analyze the data. P-values lower than 0.05 were considered to be statistically significant.
