Single Wave Study

General Information

In December 2011, the Immigrant panel was presented the questionnaire regarding volunteering with the aim of gaining insight into the effect of thinking about volunteering on the willingness to engage in all kinds of situations.    

Respondents were randomly assigned to one of three conditions.
In condition 1 respondents were asked to think about a situation in which they had helped another person.
In condition 2 respondents were asked to remember a situation in which they had thought or talked about volunteers and their various reasons to do voluntary work.
In condition 3 respondents were asked to remember one of their typical days.  

Respondents described these situations and were asked a few questions about the described situation.  

At the end of the questionnaire respondents were presented with all sorts of statements about (helping) behavior. They were asked to indicate to what extent they would be willing to engage in that behavior.
