Evaluation of three interventions to promote workplace health and safety: evidence for the utility of implementation intentions

This article evaluates a motivational intervention based on the theory of planned behavior, a volitional intervention based on implementation intentions. and a combined motivational plus volitional intervention in promoting attendance at workplace health and safety training courses in the UK. Intervention manipulations were embedded in postal questionnaires completed by participants (N = 271). Subsequent attendance over a 3-month period was determined from course records. Findings showed that the volitional and combined interventions doubled the rate of attendance compared to the motivational and control conditions (rates were 39%. 32%. 12%, and 161, respectively). The effects of the volitional intervention were independent of the effects of previous attendance. demographic variables, employment characteristics. and variables from the theory of planned behavior.
