In order to determine the effect of organisational structures on the behaviour of legislative staff of the EP, data was collected with a survey. The collected data was then analysed with cross-tabulation and regression techniques. The hypotheses were tested while controlling for demographic characteristics (i.e. citizenship, age, education, gender, party membership, tenure) and working attitudes.

How was behaviour measured?

In order to measure behaviour, respondents were asked how frequently they perform a series of tasks. Given their answers, a scale measuring the behaviour of legislative staff was constructed with a principal component factor analysis. As a statistical technique, the principal component factor analysis identifies a limited number of items, which represent the core of a set of items. These items are then transformed into a scale. In this study, the core of the activities consisted of seven tasks: offering political or voting advice, contributing to policy ideas, preparing amendments and reports, participating in the negotiations with political groups, coordinating MEPs’ positions and preparing of voting lists. The scale was named legislative assistance.
