Prevalence of psychotic-like experiences in young adults with social anxiety disorder and correlation with affective dysregulation.

Social anxiety disorder (SAD) is associated with psychotic-like experiences (PLEs) and is a frequent diagnosis in the prodromal phases of psychosis. We investigated whether psychopathological factors could discriminate which subjects with SAD are more likely to develop PLEs. A sample of 128 young adults with SAD was split into two subsamples according to the presence of clinically relevant PLEs. Correlations between PLEs and other psychopathological markers were explored. The SAD with PLEs group showed higher level of anxiety, depression, and intolerance of uncertainty (IU) compared with the SAD without PLEs group. A limitation of this study is that the cross-sectional design precluded the analysis of causality. In our sample, the presence of PLEs is related to higher levels of depression, anxiety, and IU. The current findings are consistent with hypotheses suggesting that cognitive disturbances, together with social anxiety, may result in PLEs.

[Emerging mental disorders in a community sample of young adults in Italy: help-seeking in a Generalist Community Mental Health setting]. / Disagio mentale in un campione comunitario di giovani adulti: l'help-seeking in un modello generalista di salute mentale.

AIM: Delays in the admission to care of young adults with emerging mental disorders represent one of the current major concern in psychiatry. This delay, often experienced in clinical practice, has several determinants. One of these is "unexpressed help-seeking" that is influenced by cultural and historical backgrounds and by the characteristics of the disorder itself, but most of all by the way community mental health services are developed. The aims are to identify: level of stress and mental unease and main determinants of unexpressed help-seeking within a community sample of young adults in a national contest of generalist community mental health model. METHODS: the sample is made up of 3,446 university students. An explorative questionnaire together with SVS (Stress related Valuation Scale) for the assessment of subjective stress and GHQ-12 for the evaluation of mental health status were given. A descriptive analysis was carried out followed by correlations between unexpressed help-seeking variable and other variables. A logistic regression was carried out on the subsample with GHQ-12 ≥4 utilizing "non help-seeking" as a dependent variable. RESULTS: 46.8% of the sample had a GHQ-12 ≥4 score. The amount of unexpressed help-seeking is equal to 63.6% and ends up being significantly correlated to: male sex, nonresident student, high SVS score, absence of Youth Mental Health Services, distrust manifested in relation to existing Services. CONCLUSIONS: A modification of the Community Mental Health Services in the sense of setting up more appropriate contexts for young users, could lead to a reduction of unexpressed help-seeking.

[Subtypes of psychotic-like experiences in a community sample of young adults: socio-demographic correlates and substance use]. / Sottotipi di "psychotic-like experiences" in un campione comunitario di giovani adulti: correlati socio-demografici e uso di sostanze.

AIM: This study aimed to investigate if particular psychotic-like experiences (PLEs) subtypes were more likely to be associated with a series of socio-demographic variables, with alcohol abuse and with cannabis or illicit drug use. The idea is to further characterize different PLEs subtypes in order to discloud their individual nature. METHODS: A cross-sectional design was conducted on a sample of 997 university students aged between 19 and 26 years, which belonged to 4 faculties of 2 different universities. Alcohol abuse and cannabis or illicit drug use were assessed using a self-report questionnaire; PLEs were assessed using the Community Assessment of Psychic Experiences. Cases were randomized in order to obtain equipotent groups; then, an analysis of the probable dependence relations between PLEs subtypes and other variables was conducted using analysis of variance models. RESULTS: Persecutory ideas (PI) and bizarre experiences were more frequent within females and non-resident students, moreover PI were more frequent within younger subjects (<20 years). Magical thinking was significantly associated to a more frequent cannabis use in the last year (>1/month). CONCLUSIONS: These results confirm usefulness and validity of a "subtype approach" to PLEs. In fact PLEs subtypes may have, not only a different clinical presentation, but even different epidemiological and psychopathological ones.

Psychotic experience subtypes, poor mental health status and help-seeking behaviour in a community sample of young adults.

BACKGROUND: Different subtypes of psychotic experiences (PEs) have been identified in clinical and non-clinical samples. Researchers have considered these PEs to either be variations of personality or expressions of vulnerability to psychotic disorder. This study aimed to determine which particular subtypes of PEs were more likely to be associated with poor mental health status and help-seeking behaviour in a non-clinical sample of young adults. METHODS: The study was conducted on a community sample of 997 young adults. The prevalence of PEs and distress was measured using the community assessment of psychic experiences (CAPE), depressive and anxiety symptoms were measured using Beck depression inventory-II and Beck anxiety inventory, and general functioning was measured using the general health questionnaire-12. Factorial analysis of the CAPE positive dimension was conducted and correlations between factors and clinical variables were analysed. RESULTS: Four PE subtypes were identified: perceptual abnormalities, persecutory ideas (PI), bizarre experiences, and magical thinking. At least one high frequency PI was endorsed by 60.8% (n = 606) of the sample and proved to be significantly associated both with poor mental health status and help-seeking behaviour. CONCLUSION: PEs subtypes are differentially associated with various markers of poor mental health status. PI seem to have stronger psychopathological significance than other subtypes of PEs. Further longitudinal studies are required to extend these findings.
