Background and aim: Relationships among people at work have previously been found to contribute to the perception of having a good work. The aim of the present paper was to develop scales measuring aspects of social support, trust, and community among dentists, and to evaluate psychometric properties of the scales. Material and methods: In 2008, a questionnaire was sent to 1835 general dental practitioners randomly selected from the dental associations in Sweden and Denmark. The response rate was 68% after two reminders. Principal Component Analysis was applied to 14 items and scales were established based on the resulting factors. Internal consistency was evaluated by Cronbach’s alpha. Differential Item Functioning (DIF) with respect to gender, nationality and employment sector was analysed using ordinal logistic regression methods. Construct validity was assessed in relation to selfrated health and a range of work satisfaction outcomes. Results: The percentage of missing values on the items was low (range 0.7%–3.8%). Two scales (range 0–100) were established to measure ‘Community with Trust’ (nine items, mean = 79.2 [SD = 13.4], Cronbach’s alpha = 0.89) and ‘Collegial Support’ (five items, mean = 70.4 [SD = 20.8], Cronbach’s alpha = 0.89). DIF of only minor importance was found which supported cultural equivalence. The two scales were weakly positively correlated with each other. ‘Community with Trust’ was in general more strongly correlated with work satisfaction variables than ‘Collegial Support’ was. Conclusions: Stability and internal consistency of the scales were considered as satisfactory. Content validity and construct validity were considered as good. Further validation in other populations is recommended.
