“…Similarly, people diagnosed with schizophrenia were found to be more likely to admit beliefs in the paranormal and to report having had paranormal experiences such as telepathy, mind control or out-of-body experiences (Peters, Joseph, Day, & Garety, 2004;Preti et al, 2007). Similarly to paranormal beliefs, PLEs are also widely reported in the general population (Merckelbach & van de Ven, 2001; van Os, Linscott, Myin-Germeys, Delespaul, & Krabbendam, 2009).…”

“…Each item is rated as present (yes) or absent (no); for each item endorsed participants are required to rate the degree of distress, preoccupation and conviction associated on a five-point Likert scale Preti et al, 2007). As the number of item endorsed influences the three sub-scales scores we have devised a weighted score for distress, preoccupation and conviction (Cella, Sisti, Rocchi, & Preti, 2010).…”

“…The doubting form of the queries was thought appropriate to explore feelings and beliefs concerning experiences that are not necessarily within the dimension of psychopathology. The Italian version of the PDI (Preti et al, 2002) proved able to discriminate patients diagnosed with psychosis from controls devoid of mental disorders with a sensitivity ϭ 0.74 and a specificity ϭ 0.79 (AUC ϭ 0.815) (Preti et al, 2007).…”

Despite evidence that the reporting of delusion-like or hallucinatory experiences are predictive of the future development of a mental disorder in the spectrum of psychosis, the exact nature of such a kind of unusual subjective experience in the general population is still disputed. We investigated the multidimensionality of these experiences with the Peters et al. Delusions Inventory (PDI) and a modified Italian version of the Launay-Slade Hallucination Scale (LSHS-R) in 250 subjects of both genders drawn from the normal population, using the General Health Questionnaire (GHQ) as a measure of psychic distress of a clinically relevant nature. We found that GHQ scores are positively related to both the PDI and the LSHS-R scores, but the GHQ did not act as a mediator in the links between the 2 psychosis-proneness measures. Conversely, the LSHS-R scores fully mediated the links between GHQ and PDI scores. It can be argued that hallucination proneness and psychosis proneness do not overlap in the nonclinical population but can both cause distress separately.

“…Currently, research on the discriminative properties of the PDI (i.e., thresholds drawing on the combination of sensitivity and specificity) is scarce. To date, only one study has reported that the best PDI threshold in discriminating between cases and noncases was 8 (sensitivity, 74%; specificity, 79%) [32].…”
