“…Evidence supporting the construct validity of the 5DPT was also obtained by correlating the 5DPT with the SSQ (Van Kampen, 2006b), the CEQ (Merckelbach et al, 2001), the TS (Thalbourne, 1998), the RTS (Lange et al, 2000), TS-related scales to measure reality changes (RealCh) and spiritual experiences (SpirEx), the LSHS (Launay & Slade, 1981), and the OLIFE-UE scale (Mason et al, 1995). Given the fact that the schizoid, schizotypal, or preschizophrenic personality has been reported to exhibit features that resemble high positions on 5DPT S, N, and A, and low positions on E (see, e.g., Bleuler, 1972;Ross et al, 2002;Slater, 1953), as well as the observation that the SSQ breaks down into the correlated factors Negative Schizotypy, Asocial Schizotypy, and Positive Schizotypy (Van Kampen, 2006b), it was reassuring to see that 5DPT S turned out to correlate rather substantially with SSQ Egocentrism and 98 VAN KAMPEN Hostility (two scales that measure Asocial Schizotypy); low 5DPT E with SSQ Active Isolation and Social Anxiety (both loading on Negative Schizotypy); 5DPT N with particularly SSQ Affective Flattening and Apathy (also loading on Negative Schizotypy); and 5DPT A, albeit not very high, with SSQ Living in a Fantasy World and Delusional Thinking (both loading on Positive Schizotypy).…”
