of the parents of the participants are married and living together, almost 10% of the parents are divorced or in the middle of the divorce process, and 3.0% of the participants has lost one or both parents. Also in this sample, 96.7% of the participants had higher education, of which 78.9% did university studies. The educational level was high compared to that of the Flemish population due to the specific characteristics of the sample (students).
As a religiosity measure, all participants completed the revised 33-item Post-Critical Belief Scale (Duriez et al., 2000; Hutsebaut, 1996). The PCB provides measures of Orthodoxy (e.g., "Mary was a virgin, even if this is not compatible with modern thinking"), External Critique (e.g., "Religious faith is a sign of weakness"), Relativism (e.g., "Secular and religious conceptions of the world give valuable answers to important questions about life"), and Second Naivité (e.g., "The historical accuracy of the stories from the Bible is irrelevant for my belief in God "). The 33 items are rated on a 7-point Likert scale (1= completely opposed, 7= completely in agreement). Of these items, 8 try to capture Orthodoxy (O1, O2, O3, O4, O5, O6, O7 and O8), 9 items External Critique (E1, E2, E3, E4, E7, E8, E9, E10 and E11), 8 items Relativism (R1, R2, R3, R4, R5, R6, R10 and R11) and another 8 items Second Naivité (S1, S2, S3, S5, S6, S7, S8 and S9).
The internal consistency (Cronbach‘s Alpha) of these four quadrants is for Orthodoxy, External Critique, Relativism and Second Naivité respectively .72 (M=2.02, SD = .81) .78 (M = 3.67, SD = .94), .61 (M = 5.10, SD = .76) and .76 (M = 4.28, SD = 1.09). However, Fontaine et al. (2003) have shown that the PCB also provides measures of the two basic religiosity dimensions Wulff (1991, 1997) identified (see above). In this way, the effects
