In the match-mismatch design no effect of stage-matching the info

In the match-mismatch design no effect of stage-matching the information was found, although receiving any type of information had more effect in contemplators when compared to precontemplators.

This is in line with some earlier match-mismatch studies on smoking cessation (Dijkstra et al. 1998; Quinlan and McCaul 2000) and fruit intake (de Vet et al. 2007). These studies also failed to support the superiority of stage-matching compared to stage-mismatching, although these interventions had significantly more effect in contemplators than in precontemplators. Two other studies strongly support the idea that individuals in contemplation, Selleckchem Caspase Inhibitor VI preparation, action or maintenance stages buy GSK1210151A benefit more from any type of information than people in precontemplation stages (Dijkstra et al. 2006; Schüz et al. 2007). Since this study indicates that receiving information may influence OPs in different ways, one of the implications for practice can be to identify these groups of OPs and develop different approaches to stimulate reporting. Developing a successful approach of OPs who have little or no intention to ACP-196 chemical structure report warrants further research. Qualitative research to thoroughly assess their (lack of) motivation to report ODs, may shed light on potential barriers and enhancing factors, both on an individual and organisational level. Based

on these results, an intervention and implementation strategy may be developed. In this study, we found no significant differences between the OPs in the group of actioners that received personalized feedback when compared to OPs receiving standardized feedback. In a recent study in Sweden on reporting adverse drug reactions, the number of physicians reporting more than once in the 3-month period was significantly larger after extensive feedback, which included data from Leukotriene-A4 hydrolase scientific research, than after the usual feedback (Wallerstedt et al. 2007). Recent findings from the Dutch Pharmacovigilance Centre Lareb also underpin the influence of this type of feedback: individual feedback on the reported adverse

drug reaction with information from several sources including scientific literature was considered an important stimulus to report adverse drug reactions (Cornelissen et al. 2008). More research is needed to explore whether providing reporting OPs with personalized feedback can be a successful approach to maintain reporting behaviour.
