Something must happen before first breath.

BACKGROUND: Definition and concept of the 'beginning of human life' are weakened by co-existing contrasting hypotheses based on humanistic or religious beliefs rather than scientific foundations. This plethora of conceptually distant views have important common concerns in different fields of science and shape, in turn, several societal aspects including laws related, for instance, to inheritance eligibility or abortion, end-of-life care and euthanasia, and reproductive technology. Also, they are fundamental to evaluate opportunity for resuscitation vs. palliative care in extremely preterm infants. In this article, we address one of the most common tenets in medicine: the acceptance that human life starts with first breath, even though several events are well-documented to take place before its occurrence. MAIN TEXT: Several studies show how pivotal physiological events take place before first breath. Evidence of a number of neurological events occurring before first breath opens the way to the primacy of the Central Nervous System, given its immediate extra-uterine activation at birth. This activation eventually sets specific physiological conditions that allow the complex sequence of events determining the muscle activity associated with the influx of air in the lung and the settling of a continuous and successful extra-uterine respiration. We would like to invite the scientific community to endorse a clear-cut position against the paradigm of 'first breath' as the beginning of life. Herein, we also assume how, a still undefined, yet possibly specific quid in the external environment triggers further physiological response in newborns. Better understanding of the critical events that occur at the beginning of human life is likely to cause great concern and expectations in scientists, researchers and physicians working in the domain of brain, and its physiology, and mental health. CONCLUSIONS: The comparison between beliefs and evidence-based observations generates confusion, misperceptions and false expectations in society, hence, in the scientific and medical community. Different and more solid alternatives about the carachterization of the 'beginning of human life' are indeed available and require to be explored and defined.

Attenuated psychotic and basic symptom characteristics in adolescents with ultra-high risk criteria for psychosis, other non-psychotic psychiatric disorders and early-onset psychosis.

While attenuated psychotic symptoms (APS) and basic symptoms (BS) are the main current predictors of psychosis in adults, studies in adolescents are scarce. Thus, we (1) described the prevalence and severity of positive, negative, disorganization, general, and basic symptoms in adolescent patients at ultra-high risk for psychosis (UHR), with other non-psychotic psychiatric disorders (PC) and with early-onset psychosis (EOP); and (2) investigated BS criteria in relation to UHR criteria. Sixty-nine 12-18-year-old adolescents (15.3 ± 1.7 years, female = 58.0 %, UHR = 22, PC = 27, EOP = 20) were assessed with the structured interview for prodromal syndromes (SIPS) and the schizophrenia proneness instrument-child and youth version (SPI-CY). Despite similar current and past 12-month global functioning, both UHR and EOP had significantly higher SIPS total and subscale scores compared to PC, with moderate-large effect sizes. Expectedly, UHR had significantly lower SIPS positive symptom scores than EOP, but similar SIPS negative, disorganized, and general symptom scores. Compared to PC, both EOP and UHR had more severe basic thought and perception disturbances, and significantly more often met cognitive disturbances criteria (EOP = 50.0 %, UHR = 40.9 %, PC = 14.8 %). Compared to UHR, both EOP and PC significantly less often met cognitive-perceptive BS criteria (EOP = 35.0 %, UHR = 68.2 %, PC = 25.9 %). BS were significantly more prevalent in both EOP and UHR than PC, and UHR were similar to EOP in symptom domains. Given the uncertain outcome of adolescents at clinical high-risk of psychosis, future research is needed to determine whether the combined assessment of early subjective disturbances with observable APS can improve the accuracy of psychosis prediction.

Determinants of exclusive breastfeeding cessation: identifying an "at risk population" for special support.

UNLABELLED: A study was conducted with 542 women, who gave birth in the hospital G.B. Grassi in Rome, to investigate risk factors for exclusive breastfeeding. Clinical data was collected from clinical records at delivery. Information on psycho-socio-demographic characteristics was obtained by standardized questionnaires at delivery. Data on breastfeeding practice and the use of pacifier were collected at delivery and for 24 weeks' postpartum. The outcome of the study was exclusive breastfeeding for at least 4 months (yes/no). In the multivariate analysis, planned caesarean (OR 2.40, 95 % CI 1.06-5.43) and women with two or more psychological distress conditions (past episodes of depression, insomnia, perceive birth as a traumatic event) versus none were at a greater odds of stopping exclusive breastfeeding before 4 months (OR 3.42, 95 % CI 1.15-10.2). The use of pacifiers within the first 2 weeks postpartum (OR 2.38, 95 % CI 1.35-4.20) but not after 2 weeks (OR 0.86, 95 % CI 0.43-1.72) versus no use was also associated with an increased odds. A protective effect was found for antenatal classes (OR 0.57, 95 % CI 0.35-0.95). CONCLUSION: This study suggests that the type of delivery, antenatal classes, psychological distress conditions and the use of pacifiers in the first 2 weeks of a baby's life are independent factors associated with exclusive breastfeeding.

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.

[Challenges in the early detection of psychosis in children and adolescents]. / Le sfide per una corretta individuazione precoce delle psicosi nei bambini e negli adolescenti.

The early detection and treatment of persons at-risk for psychosis is currently regarded a promising strategy in fighting the devastating consequences of psychotic disorders. The two current at-risk approaches, i.e., the "ultra high risk" and the "basic symptom" criteria, were mainly developed on adult samples. Initial evidence suggests, however, that they cannot simply be applied to children and adolescents. For ultra high risk criteria, there is indication of some attenuated psychotic symptoms being potentially non-specific in adolescents and of brief limited intermittent symptoms being difficult to clinically classify in children when observable behavioral correlates are missing. For basic symptoms, too, only preliminary indication of their usefulness in children and adolescents exists. Since developmental peculiarities in the assessment of basic symptoms should be considered, a child and youth version of the Schizophrenia Proneness Instrument (SPI-CY) was developed. In conclusion, research on the clinical-prognostic validity of the at-risk criteria and their potential adoption to the special needs of children and adolescents is needed. If a Prodromal Risk Syndrome for Psychosis or Attenuated Psychotic Symptoms Syndrome will be included into DSM-V, it has to be highlighted that its suitability for children and adolescents is only insufficiently known.

[Drop-out risk factors in mood disorder: a clinical study]. / Valutazione del rischio di drop-out in una popolazione di pazienti affetti da disturbo dell'umore.

INTRODUCTION: The aims of this study are (i) to assess the drop-out rate in an outpatient sample with mood disorder diagnosis in a psychotherapy unit; (ii) to focus clinical and sociodemographic variables related with drop-out; (iii) to delineate a psychopathological profile of the dropping-out patient through the SCL-90-R and OPD scores. METHOD: The sample of this study includes 90 depressive patients, which came to our service for a psychotherapy. The outcome is classified as drop-out and non drop-out. Each patient is submitted to the multidimensional scale SCL-90-R in the course of the first interview. At the end of the first visit each patient has been evaluated through the first and the fourth OPD axis. A descriptive analysis of all the data collected was made and the principal links between clinical and sociodemographic variables and dropout, between SCL-90-R score and drop-out, and between OPD scores and drop-out were detected. RESULTS: About 42% of the patients were drop-out, of which 89% by the third session. The variables associated with drop-out are: pathological score in the paranoic and interpersonal sensibility scale of SCL-90-R, low compliance scores, low integration of defences, self perception, object's perception and link. DISCUSSION: The drop-out rate in depressive patients turned out to be frequent. The patient's resources in terms of relationship, self-perception and object's perception are strongly related to the drop-out risk. These results are suggestive for the idea that the evaluation of drop-out risk in psychiatric patients must considerate the subjective aspects of the patient besides the clinical features.

[Characteristics in a sample of criminal mental hospital (Castiglione delle Stiviere) inmates discharged in the Lazio region]. / Uno studio sulle caratteristiche di un campione di pazienti internati presso l'Ospedale Psichiatrico Giudiziario di Castiglione delle Stiviere e dimessi nella regione Lazio.

UNLABELLED: AIM. The aim of this study was: (i) To identify socio-demographic and clinical data in a sample of inmates in the Criminal Mental Hospital (CMH) at Castiglione delle Stiviere; (ii) to assess the presence of characteristics which could foresee the commission of a crime of psychiatric interest; (iii) to assess the frequency of crime repetition. MATERIALS AND METHODS: This study was carried out on a sample of 38 patients. A descriptive analysis of the sample was carried out and the associations among several variables were analyzed. RESULTS: The sample is characterized by a high frequency of schizophrenia diagnosis (73.0%), the presence of hospitalization before the commission of the crime (68.4%) and the absence of criminal precedents (71.1%). For men the age of the commission of the crime is equal to 33.72 +/- 10.6 years and for women to 45.18 +/- 11.4 years (p = 0.011). The time between the onset and the commission of the crime is longer in patients who have received therapy (treatment) than in those ones with no treatment (p = 0.012). About 12% of the sample committed new crimes. CONCLUSIONS: The results showed previous criminal acts are not predictive for the commission of new crimes of psychiatric interest. However many patients had previous contacts with community facilities before their first admission to hospital and the treatment extended the interval between the onset of the disease and the commission of the crime. The relapse rate after the discharge was very low if compared with samples coming from other services that offered more custodial rather than rehabilitative facilities.

Interpersonal sensitivity, bullying victimization and paranoid ideation among help-seeking adolescents and young adults.

AIM: The effects of a negative interpersonal experience, such as bullying victimization in childhood and adolescence, can be strong and long lasting. Bullying victimization is associated with paranoid ideation and suspiciousness. Few studies have focused on personality traits of victims of bullying. The aim of this study is to investigate whether a particular personality trait called interpersonal sensitivity may be related to suspiciousness in those who experienced bullying victimization. METHODS: The study sample consisted of 147 help-seeking adolescents (mean age 17 years) selected after a screening phase (Prodromal Questionnaire) and evaluated with the Structured Interview for Psychosis-risk Syndromes (SIPS). All participants were specifically asked if they had experienced either psychological bullying or physical bullying, and they completed the Interpersonal Sensitivity Measure (IPSM). RESULTS: Of the whole sample, 30 (20%) participants had experienced psychological bullying or physical bullying at least once in their life. Performing a multiple regression, bullying victimization was found to be an independent predictor of subtle paranoid ideation and suspiciousness. Interpersonal sensitivity was also found to be an independent predictor of subtle paranoid ideation; in particular, two IPSM subscales, fragile inner-self and separation anxiety, showed a significant correlation with subtle paranoid ideation. CONCLUSIONS: Our results confirmed that bullying victimization is a negative interpersonal experience associated with paranoid ideation and suspiciousness. However, being overly sensitive and having negative beliefs about the self as fragile and vulnerable to threat also lead to a tendency to attribute experiences as externally caused and, in turn, facilitate the formation and maintenance of paranoid ideation.

Suicide risk and exposure to mobbing.

The aim of this study was to study suicide risk in subjects exposed to mobbing, that is, systematic psychological harassment in the workplace. Such psychological harassment, unique to the workplace, threatens both the emotional well-being and professional ability of its victims. The items of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) that assess suicide risk were studied in 102 individuals who were exposed to mobbing. The results indicated that individuals exposed to mobbing had clear differences on the MMPI-2 from normative samples. In addition, those who appeared to be at risk for suicide differed in their scores from those not at risk. Implications for psychopathology and suicide preventions are discussed.

Developmental vulnerability to psychosis: Selective aggregation of basic self-disturbance in early onset schizophrenia.

Trait-like anomalies of subjective experience (aka, Basic Self-disturbance or Self-disorder, SD) have been empirically identified as schizophrenia-specific markers of vulnerability in several clinical and genetic high-risk populations. However, such specificity is still to be tested in developmental years, where emerging psychopathology is less crystallized and diagnostic boundaries more blurred. Thus, the current study explores the distribution of SD in adolescent help-seekers (age range 14 to 18) and tests the specificity of SD with respect to the severity of their diagnostic staging (Early Onset schizophrenia-spectrum psychosis [EOP], ultra high-risk [UHR] and clinical help-seeking controls [CHSC]). For this purpose, 96 help-seeking adolescents consecutively referred to specialized Child and Adolescent Units for diagnostic evaluation, underwent a comprehensive psychopathological examination including the specific interview for SD (i.e. the Examination of Anomalous Self-Experience, EASE). One-way ANOVA was used to test the diagnostic distribution of SD (EASE score), whereas multinomial logistic regression was used to test the effect of SD on the diagnostic outcome. SD frequency (both in terms of EASE total score and domain sub-scores) was decreasing progressively from EOP to CHSC, with intermediate levels in UHR. The EASE total score increased the risk of belonging to the more severe diagnostic stages (i.e, UHR and EOP vs CHSC as reference class) and allowed the correct reclassification of the 75% of the sample. The results confirm the schizophrenia-spectrum specificity of SD in adolescence, highlighting their potential value for early differential diagnosis and risk stratification.

Youth mental health services in Italy: An achievable dream?

AIM: "Liberiamo il futuro" (LIF) project was designed to assess psychological problems of adolescents and young adults and to identify individuals at high-risk for developing a psychosis through a collaboration between a University team, Child and Adolescent Mental Health Services and Adult Mental Health Services. This paper presents the baseline demographic and clinical characteristics of the cohort, particularly the nature and severity of psychopathology. METHOD: All help-seeking young people aged 12-35 years residing in the health district involved in LIF were invited to participate in the study and completed a battery of self- report and interviewer-administered measures of psychopathology and functioning at baseline. RESULTS: A total of 338 adolescents and young people (mean age 17.42) participated in the study. The majority of the sample (n = 107, 35%) had an anxiety disorder, followed by mood disorders (n = 62, 21%). Only 35 (12%) participants had no psychiatric diagnosis. After a screening phase, 166 (52%) individuals were assessed to detect the presence of an Ultra High Risk (UHR) state. Of these, 38.60% (n = 64) met UHR criteria. Overall, the majority of the sample resulted moderately functionally impaired at baseline. CONCLUSIONS: LIF project showed that psychological problems, associated with impaired psychosocial functioning, are very common among help-seeking young people. The help-seeking behaviour of young people is in contrast with the barriers presented by the Italian community mental health system that is modelled around adults' requirements. A need of a strong, stigma-free, young oriented system of care for young people up to the mid-20s emerged.

Secondary school teachers and mental health competence: Italy-United Kingdom comparison.

AIM: The aim of this study was to evaluate the differences between teachers' knowledge about early psychosis among three different Italian cities and a UK sample. METHODS: The sample consisted of 556 secondary school teachers from three different cities in Italy (Milan, Rome and Lamezia Terme) and London (UK). The research was based on the Knowledge and Experience of Social Emotional Difficulties Among Young People Questionnaire. The Italian version of the questionnaire was used in Italy. RESULTS: Overall, 67.6% of English teachers, 58.5% of Milan's teachers, 41.8% of Rome's teachers and 33.3% of Lamezia Terme's teachers were able to recognize psychotic symptoms from a case vignette. Logistic regression analysis showed that 'city' was the only independent variable significantly related to the correct/wrong answer about diagnosis. CONCLUSIONS: We found statistically significant differences between the three Italian samples and the UK sample regarding teachers' knowledge about first signs of psychosis. English teachers showed a better knowledge than Italian teachers in general. Teachers from Milan, where a specific early detection program was established in 2000, seemed to be more familiar with early signs of psychosis than teachers in the other two Italian towns.

The Italian version of the 92-item Prodromal Questionnaire: Concurrent validity with the SIPS and factor analysis in a sample of 258 outpatients aged 11-36years.

BACKGROUND: Current early screeners for psychosis-risk states have still to prove ability in identifying at-risk individuals. Among screeners, the 92-item Prodromal Questionnaire (PQ-92) is often used. We aimed to assess the validity of its Italian translation in a large Italian adolescent and young adult help-seeking sample. METHODS: We included all individuals aged 12-36years seeking help at psychiatric mental health services in a large semirural Roman area (534,600 population) who accepted to participate. Participants completed the Italian version of the PQ-92 and were subsequently assessed with the Structured Interview of Prodromal/Psychosis-Risk Syndromes (SIPS). We examined diagnostic accuracy (sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios) and content, concurrent, and convergent validity between PQ-92 and SIPS using Cronbach's alpha, Cohen's kappa, and Spearman's rho, respectively. We tested the validity of adopted cut-offs through Receiver Operating Characteristic (ROC) curves plotted against SIPS diagnoses and the instrument's factor-structure through Principal Component Analysis. RESULTS: PQ-92 showed high internal consistency, acceptable diagnostic accuracy and concurrent validity, and excellent convergent validity. ROC analyses pointed to scores of 18 on the Positive subscale and 36 on the total PQ-92 as best cut-offs. The Scree-test identified a four-factor solution as fitting best. CONCLUSIONS: Psychometric properties of Italian PQ-92 were satisfactory. Optimal cut-offs were confirmed at ≥18 on the positive subscale, but at ≥36 on the total scale was able to identify more SIPS-positive cases.

Impairment in Social Functioning differentiates youth meeting Ultra-High Risk for psychosis criteria from other mental health help-seekers: A validation of the Italian version of the Global Functioning: Social and Global Functioning: Role scales.

Social and occupational impairments are present in the schizophrenia prodrome, and poor social functioning predicts transition to psychosis in Ultra-High Risk (UHR) individuals. We aimed to: 1) validate the Italian version of the Global Functioning: Social (GF: S) and Global Functioning: Role (GF: S) scales; 2) evaluate their association with UHR criteria. Participants were 12-21-years-old (age, mean=15.2, standard deviation=2.1, male/female ratio=117/120) nonpsychotic help-seekers, meeting (N=39) or not (N=198) UHR criteria. Inter-rater reliability was excellent for both scales, which also showed good to excellent concurrent validity, as measured by correlation with Global Assessment of Functioning (GAF) scores. Furthermore, GF:S and GF: R were able to discriminate between UHRs and non-UHRs, with UHRs having lower current scores. After adjusting for current GAF scores, only current GF:S scores independently differentiated UHR from non-UHR (OR=1.33, 95%CI: 1.02-1.75, p=0.033). Finally, UHR participants showed a steeper decrease from highest GF:S and GF: R scores in the past year to their respective current scores, but not from highest past year GAF scores to current scores. GF:S/GS: R scores were not affected by age or sex. GF:S/GF: R are useful functional level and outcome measures, having the advantage over the GAF to not confound functioning with symptom severity. Additionally, the GF:S may be helpful in identifying UHR individuals.

Self-Disorders and Clinical High Risk for Psychosis: An Empirical Study in Help-Seeking Youth Attending Community Mental Health Facilities.

Anomalous subjective experiences involving an alteration of the basic sense of self (ie, Self-disorder [SD]) are emerging as a core marker of schizophrenia spectrum disorders with potential impact on current early detection strategies as well. In this study, we wished to field-test the prevalence of SD in a clinical sample of adolescent/young adult help-seekers at putative risk for psychosis attending standard community mental health facilities in Italy. Participants (n = 47), aged between 14 and 25, underwent extensive psychopathological evaluations with current semi-structured tools to assess Clinical High Risk (CHR) state (ie, Structured Interview for Prodromal Syndromes/Scale of Prodromal Symptoms [SIPS/SOPS], Schizophrenia Proneness Instrument-Adult/Child and Youth [SPI-A/CY]). SD aggregated in CHR subjects as compared to the non-CHR and revealed substantial association with sub-psychotic symptoms (SIPS), subjective experience of cognitive and cognitive-perceptual vulnerability (basic symptoms) and functional level (Global Assessment of functioning). Moreover, a combination of the 2 approaches (ie, CHR plus SD) enabled further "closing-in" on a subgroup of CHR with lower global functioning. The results confirm SD's relevance for the early profiling of youths at potential high risk for psychosis.

Self-reported attenuated psychotic-like experiences in help-seeking adolescents and their association with age, functioning and psychopathology.

OBJECTIVE: Self-rated attenuated psychotic-like experiences (APLEs) are increasingly used to screen for ultra-high-risk (UHR) across all ages. However, self-rated psychotic-like experiences (PLEs), in particular perception-related ones, were more frequent in children and adolescents, in which they possessed less clinical significance. We therefore explored the prevalence of different factors of APLEs in help-seeking adolescents, and their relationship with age, functioning and psychopathology. METHOD: As a part of the "Liberiamo il Futuro" project, help-seeking adolescents (N=171; 11-18 years, 53% male) were screened with the 92-item Prodromal Questionnaire (PQ-92). A factor analysis was performed on the PQ-92 positive items (i.e., APLEs) to identify different APLE-factors. These were assessed for their association with age, functioning and psychopathology using regression analyses. RESULTS: APLEs were very common in help-seeking adolescents, and formed four factors: "Conceptual Disorganization and Suspiciousness", "Perceptual Abnormalities", "Bizarre Experiences", and "Magical Ideation". Associations with age and functioning but not psychopathology were found for "Perceptual Abnormalities" that was significantly more severe in 11-12-year-olds, while "Conceptual Disorganization and Suspiciousness" was significantly related to psychopathology. CONCLUSION: In line with findings on PLEs, prevalence and clinical significance of APLEs, especially perception-related ones, might depend on age and thus neurodevelopmental stage, and may fall within the normal spectrum of experience during childhood. This should be considered when screening for UHR status in younger age groups.

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.
