The second study is part of a more complex research, from which we retrieved only the aspects concerning the
OCB and its correlates. The participants were 56 employees (33 female, 23 male) from the public (55.3%) and
private sectors (44.7%). The two institutions from the public sector are a public school and a foster care centre.
From an educational level perspective, 26.8% of the participants are secondary education graduates, whereas 73.2%
are higher-education graduates. Our hypothesis stated that the OCB is associated with work satisfaction, and that
there are differences between the employees of the private and public sectors as far as their availability to undertake
extra activities is concerned. We also assumed that women display OCB more often than men.
Various instruments were used, out of which relevant for the present article are the Organisational Citizenship
Behaviour Questionnaire (OCBQ, Tătaru & Tătaru, 2003), described in the first study, and the Job Satisfaction
Questionnaire (adapted after Zamfir, 1980), comprising 16 items with answers displayed on a Likert scale, and
having a good internal consistency of Cronbach coefficient alpha .88.
