“…14, [16][17][18]32,38,40]. Positive correlations between age and negative symptoms have also been reported [37,38], although Badcock and Dragovic [41] did not find any such associations. As with gender, therefore, the findings on the association between schizotypy and age are inconclusive.…”

“…Previous studies have shown that both, gender and age play an important role on the distribution of schizotypal characteristics in normal and clinical samples (e.g. [14,36,38]). Previous studies have also examined the factorial invariance of the SPQ across age and gender.…”

“…Fossati et al [14] examined the factorial invariance of the three-factor model and using EFA they found that the three-factor structure of the nine SPQ scales was highly invariant across high school and university students. Fonseca-Pedrero et al [38] examined the factorial invariance of the Schizotypal Personality Questionnaire-Brief [SPQ-B; 68] across gender and age. They found that SPQ-B exhibits factorial invariance across gender but not across different age groups.…”

“…With regard to gender, most studies have reported that males in the general population have increased negative and disorganization traits compared with females [14,[33][34][35][36], although one study reported that females have higher negative traits than males [37]. Studies examining gender differences in positive traits are also inconclusive, as there are reports of both females [14,34,38] and males [35] scoring higher in this dimension as well as studies finding no gender differences [36,37,39]. Regarding age, there are consistent findings indicating that there is a negative correlation between age and positive schizotypal traits in the general adult population [e.g.…”

“…These broadly correspond to the positive, disorganised and negative dimensions of schizophrenia (SZ) respectively (Compton et al, 2009;Fonseca-Pedrero et al, 2011;Nelson et al, 2013). The fully dimensional approach posits that schizotypal traits in the healthy population and SZ are fundamentally linked (Claridge and Beech, 1995;Nelson et al, 2013).…”

The fully dimensional approach to the relationship between schizotypal personality traits and schizophrenia describes schizotypy as a continuum throughout the general population ranging from low schizotypy (LoS) and psychological health to high schizotypy (HiS) and psychosisproneness. However, no biological markers have yet been discovered that reliably quantify an individual's degree of schizotypy and/or psychosis. This study aimed to evaluate quantitative electroencephalographic (qEEG) measures of power spectra as potential biomarkers of the proneness towards the development of psychosis in schizotypal individuals. The resting-state oscillatory brain dynamics under eyes-closed condition from 16 LoS and 16 HiS individuals were analysed for qEEG measures of background rhythm frequency, relative power in δ, θ, low-α, high-α, low-β, high-β and low-γ frequency bands, and the high-temporal crosscorrelation of power spectra between low-and high-frequency bands observed by averaging signals from whole-head EEG electrodes. HiS individuals at rest locked the thalamocortical loop in the low-α band at a lower-frequency oscillation and displayed an abnormally high level of neural synchronisation. In addition, the high-α band was found to be positively correlated with both the high-β and low-γ bands unlike LoS individuals, indicating widespread thalamocortical resonance in HiS individuals. The increase of regional alpha oscillations in HiS individuals suggests abnormal high-level attention, whereas the pattern of correlation between frequency bands resembles the thalamocortical dysrhythma phenomenon which underlies the symptomatology of a variety of neuropsychiatric disorders including schizophrenia. These qEEG biomarkers may aid clinicians in identifying HiS individuals with a high-risk of developing psychosis.

Sex differences and gender‐invariance of mother‐reported childhood problem behavior

Prevalence and severity of childhood behavioral problems differ between boys and girls, and in psychiatry, testing for gender differences is common practice. Population-based studies show that many psychopathology scales are (partially) Measurement Invariance (MI) with respect to gender, i.e. are unbiased. It is, however, unclear whether these studies generalize towards clinical samples. In a psychiatric outpatient sample, we tested whether the Child Behavior Checklist 6-18 (CBCL) is unbiased with respect to gender. We compared mean scores across gender of all syndrome scales of the CBCL in 3271 patients (63.3% boys) aged 6-18. Second, we tested for MI on both the syndrome scale and the item-level using a stepwise modeling procedure. Six of the eight CBCL syndrome scales included one or more gender-biased items (12.6% of all items), resulting in slight over- or under-estimation of the absolute gender difference in mean scores. Two scales, Somatic Complaints and Rule-breaking Behavior, contained no biased items. The CBCL is a valid instrument to measure gender differences in problem behavior in children and adolescents from a clinical sample; while various gender-biased items were identified, the resulting bias was generally clinically irrelevant, and sufficient items per subscale remained after exclusion of biased items.
