Campo-Arias A, Herazo E, Caballero-Domínguez CC. Prodromal questionnaire (PQ-16) dimensionality among Colombian adolescent school students. Early Interv Psychiatry 2024. [PMID: 38738641 DOI: 10.1111/eip.13546] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 05/01/2024] [Accepted: 05/06/2024] [Indexed: 05/14/2024]
Abstract
AIMS The study aimed to determine the dimensionality of the Spanish version of the PQ-16 among Colombian adolescent school students. METHODS A validation study was designed with the participation of 334 Colombian adolescent students aged between 13 and 17 (M = 15.2, SD = 1.1); 171 (52.1%) were girls, and 163 (47.9%) were boys, 229 (68.6%) were ninth-grade students and 105 (31.4%) were tenth-grade students. Confirmatory factor analysis was performed, internal consistency was calculated with the Kuder-Richardson and McDonald's omega tests, and correlation with suicide ideation was computed with the Kendall correlation (r). RESULTS The confirmatory factor analysis showed that the PQ-16 adequately fit a unidimensional structure: RMSEA = 0.05 (90%CI 0.04-0.06), CFI = 0.91, TLI = 0.90, SRMR = 0.05, chi-squared = 193.18 (df = 102, p < 0.001) and normalized chi-squared = 1.89. This factor presented high internal consistency: Kuder-Richardson test and McDonald's omega of 0.83. The correlation between the PQ-16 and suicide ideation was r = 0.45 (p < 0.001). CONCLUSION The PQ-16 is a one-dimensional tool with high internal consistency and correlation with suicide ideation among schooled adolescents. Further research should explore the PQ-16 performance against a structured clinical interview.

The structure of the Prodromal Questionnaire-16 (PQ-16) in a non-help-seeking youth population: Exploratory and confirmatory factor analyses study. Schizophr Res 2023; 261:281-286. [PMID: 37871410 DOI: 10.1016/j.schres.2023.10.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 07/25/2023] [Accepted: 10/18/2023] [Indexed: 10/25/2023]
Abstract
AIMS The present study aimed to examine the structure of the Prodromal Questionnaire-16 (PQ-16) in a non-help-seeking youth population through exploratory and confirmatory factor analysis. Previous studies have not examined the structure of this self-report measure in this age group outside a clinical setting. METHODS Participants (n = 1165) aged 11-19 years were recruited to an epidemiological study of young people in Northern Ireland, and completed the PQ-16 alongside other measures. The dataset was split randomly in two for separate factor analyses. A polychoric correlation matrix was created and exploratory factor analysis was used to identify the optimal number of factors. In addition, based on previous studies, six models were tested through confirmatory factor analysis to determine best fit. A one-factor, 3 two-factor, a three-factor and a four-factor model were all tested. RESULTS The exploratory factor analysis indicated a two-factor structure of the PQ-16 in this population, which we have labelled 'general unusual experiences' and 'hallucinations'. Confirmatory analysis indicated that the two-factor model identified through the exploratory analysis was the best fit for the data. DISCUSSION The present study suggests that the structure of the PQ-16 may vary across age groups in non-clinical settings, and adds further support to the validity of the PQ-16 is a cost-effective, easy to administer self-report measure that is suitable for use in non-help-seeking populations as a screening tool for prodromal symptoms.

Abstract
AIM The present study aimed to investigate the prevalence rate of objective and subjective psychosis-like experiences (PLEs) in non-help-seeking college students and to explore their differential contributions to suicidal ideation. METHODS First-year college students were recruited and surveyed with the Chinese version of the 16-item Prodromal Questionnaire (CPQ-16), Childhood Trauma Questionnaire (CTQ-SF), Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder-7 (GAD-7) and Beck Scale for Suicide Ideation (BSI). The Structured Interview of Psychosis-Risk Syndromes (SIPS) was conducted in individuals with a CPQ-16 score of 9 or higher. RESULTS Data were available for 8367 students. Three hundred and seventy of them scored 9 or higher on the CPQ-16, suggesting potential PLEs (4.42%). Among them, 194 agreed to the SIPS screening. The PLEs were confirmed in 103 individuals who scored 1-5 on any positive symptom scales of the SIPS (objective PLEs, oPLEs). For the remaining 91 individuals, their PLEs were not confirmed by the SIPS and thus were categorized as individuals with subjective PLEs (sPLEs). In univariate logistic regression, oPLEs was associated with a two times risk of suicidal ideation compared to sPLEs (OR = 1.971, p = .029). In multivariate logistic regression when non-PLE status was set as a reference, oPLEs significantly predicted suicidal ideation (OR = 3.441, p = .011), while the sPLEs (OR = 2.277, p = .091) was no longer a significant predictor after controlling for PHQ-9, GAD-7 and CPQ-SF scores. CONCLUSIONS OPLEs and sPLEs have differential contributions to suicidal ideation. OPLEs seems to be associated with a higher risk of suicidal ideation and is independent of other psychopathology.

Front Psychiatry 2022; 13:839630. [PMID: 35573375 PMCID: PMC9096161 DOI: 10.3389/fpsyt.2022.839630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2021] [Accepted: 02/23/2022] [Indexed: 11/21/2022] Open
Abstract
OBJECTIVES Both bullying and psychosis-like experiences (PLEs) have gained much attention in recent years, but their interactions are not fully unraveled. The aim of the current study was to validate the Chinese version of Bullying Scale for Adults (C-BSA), and to investigate whether past bullying experiences independently predict the presence of PLEs in university students. METHODS The validity and reliability of the C-BSA were determined in two independent samples. A battery of psychological inventories was also administered to assess the presence of PLEs, maltreatment history in the family, and current depression and anxiety, including the 15-item positive subscale of the community assessment of psychic experiences (CAPE-p15), the Chinese version of the Childhood Trauma Questionnaire (CTQ), Self-Rating Depression Scale (SDS), and Self-Rating Anxiety Scale (SAS). RESULTS In the construction sample (N = 629), a Cronbach's α of 0.921 indicated a good internal consistency of C-BSA. The exploratory factor analysis (EFA) yielded a four-factor model and a three-factor model, and both were verified by using the confirmatory factorial analysis (CFA) in the validation sample (N = 629). The total scores of C-BSA were significantly correlated with that of CTQ, CAPE-p15, SDS, and SAS. Multivariate logistic regression revealed that bullying was associated with 2.0 or 3.7 times of risk for the presence of PLEs (numbers of bullying types < = 3 or > 3, respectively) after controlling for CTQ, SDS, and SAS scores. CONCLUSIONS C-BSA has shown good psychometric properties in college students. The contribution of past bullying experiences to the present PLEs seems to be independent of other childhood trauma, current depression, and anxiety.

Abstract
AIM Non-suicidal self-injury (NSSI) is common among adolescents, and several different factors can affect its prevalence. The present study examined the associated characteristics predicting NSSI among adolescents in South Korea. METHODS In total, 1674 high school students were recruited for a cross-sectional survey. They completed self-reported assessments, including the Deliberate Self-Harm Inventory (DSHI), the Center for Epidemiological Studies Depression Scale (CESD), the State-Trait Anxiety Inventory for Children (STAIC), and the Prodromal Questionnaire-16 (PQ-16), as well as their bullying experience. The NSSI group was defined as the sample group with at least one NSSI behaviour on the DSHI scale. A logistic regression analysis was performed using the NSSI group as the dependent variable. RESULTS The prevalence of NSSI was 28.3% (boys, 30.4%; girls, 24.4%) among adolescents. The most common type of NSSI behaviour among adolescents was interference with wound healing and sex differences in the method were examined. The CES-D, STAIC-trait, and PQ-16 scores were significantly higher and the RSES score was significantly lower in the NSSI group than those in the non-NSSI group. Participants' experience with bullying, such as being victims, bullies, bully-victims, and witness to bullying, were more likely to be in the NSSI group. In a logistic regression analysis, NSSI was significantly associated with male sex, low academic achievement, higher depression, psychotic-like experiences, being bullied, and witnessing bullying. CONCLUSION The results of this study suggest the need to identify and manage related psychologic factors in adolescents with NSSI, including psychotic-like symptoms.

Abstract
BACKGROUND Psychotic-like experiences (PLEs) might occur in the general population as low-risk individual differences or prodromal features, requiring quick detection and early intervention. The aims of this study were to conduct a mini-systematic review of the prognostic abilities of the Prodromal Questionnaire-Brief (PQ-B), describe the PLEs distribution for the first time in a Polish population, assess PQ-B reliability and propose an innovative scoring approach based on cluster analysis. METHODS Five hundred and twenty eight (334 female) adult volunteers underwent screening with the PQ-B, 49% also underwent the early psychosis screening test PRIME, to verify the tests' psychometric properties, to compare the prognostic accuracy of the PQ-B to the more restrictive PRIME, and to the detected types of possible diagnosis in the general population. RESULTS Almost 70% of respondents met the prognostic criteria of the PQ-B while only 30.6% met the PRIME criteria. Both tests proved reliable (α > .835) and valid (rho >.710; P < .001). A cluster analysis identified three different sub-groups detected with the PQ-B: healthy individuals without PLE; healthy with low-distressing PLEs; and possibly prodromal subjects reporting less frequent but more distressing PLEs and no worries about their own mental state. Also in systematic reviews, authors of different adaptations have observed that the PQ-B has too low specificity and postulated the need for higher cut-offs. CONCLUSION Study provides evidence of good reliability and sensitivity of the PQ-B in assessing PLEs among the general population, but emphasizes that straightforward quantitative scoring criteria are still unclear. A more qualitative approach might be useful for differentiating true prodromal subjects from clinically low-risk individual differences.

Abstract
AIM In many Asian countries, youth mental health services are not well-developed and access to treatment is generally delayed. Here, we present a community-based service model based on our experience with Mindlink, the first early-intervention centre of its kind in Korea. METHODS We describe the history of this mental health early-intervention service and the characteristics of users, as well as its intervention programmes and research directions. We also propose ways to further develop youth mental health services. RESULTS A community-based early-intervention service for youth was first introduced in 2012, when a special team was formed in a community mental health centre of Korea. As the numbers of young clients increased, a youth-friendly, early-intervention centre called Mindlink was opened in 2016. Mindlink targets those aged 15-30 years with mental illness less than 5 years in duration. Its goal is to detect mental illness in young people early and provide comprehensive multidisciplinary interventions. It provides intensive case management and group programmes including cognitive-behavioural therapy, family intervention, psychoeducation, behavioural activation and physical health promotion. The Korean government has officially announced that the Mindlink model is effective and is currently in the process of scaling it up on a national level. CONCLUSION An accessible, youth-friendly, stigma-free, community mental health centre such as Mindlink allows early detection and appropriate management of mental illness in young patients.

Abstract
INTRODUCTION The duration of untreated psychosis has been largely associated with poor outcomes in psychosis. Actual diagnostic tools may be used by very specialized teams and need sustained evaluation. We present a French version of a self-report questionnaire: the 16-item Prodromal Questionnaire (fPQ16). Our objective was to evaluate its predictive value for an ultra-high-risk state (UHR) or psychosis. The population enrolled was consulting in a young adults and adolescents center in Sainte-Anne hospital, Paris, France. METHODS PQ16 had first been translated into French and independently back translated and validated by the original authors. Between November 2016 and May 2018, every C'JAAD consulting patient was proposed to fill in the fPQ16. Each patient was next evaluated with the French version of the comprehensive assessment of at-risk mental state (CAARMS), which detects UHR or psychosis. Statistical analysis of fPQ16 concurrent validity was performed using ROC curves. fPQ16 acceptability was studied by four additional questions especially designed for that purpose. RESULTS One hundred participants were included. Mean age was 19.85years (SD 3.3 y). Fifty-eight percent of patients included were diagnosed with UHR (40%) or psychotic (18%) state after CAARMS evaluation. Mean score at fPQ16 was 5.7 (SD 3.8). Best cut-off score was 4 positive items, with excellent sensibility (91%) and correct specificity (60%). Positive predictive value of fPQ16 was 76%. Area under the curve was 0.85 (P<0.0001). fPQ16 showed good acceptability. DISCUSSION fPQ16 had good screening performances in our population. Cut-off score was lower than in previous studies, but performances were equal or better. As a well-accepted and short questionnaire, the fPQ16 could be a great screening tool in primary care. A version with 18-items, including two items focused on thought content and disorganization that are missing in PQ16, is under evaluation.

Abstract
South Korea was able to successfully control the spread of COVID-19 without nationwide lockdowns or drastic social distancing efforts, but pandemic-related psychological outcome of the general population remains unknown. Between March and June 2020, 400 South Korean residents participated in an online study of depression, anxiety, stress, psychosis-risk and loneliness, as well as indices of social network, physical health and demographics. Clinical levels of depression, anxiety or stress were reported by 45% of the respondents, and psychosis-risk was present in 12.8%; a drastic increase above the base rate reported by previous studies conducted in South Korea prior to the pandemic. Subjective feelings of loneliness, but not the size of the social network accounted for poor mental health. Women were especially at increased risk for mental health problems. Thus, despite effective mitigation of the pandemic, there was a striking deterioration of mental health. As the psychological burden of the continuing pandemic accrues, the probability of an impending mental health crisis is increasing, especially in countries with greater infection and death rates than South Korea. Comprehensive efforts to address the psychological aftermath of the pandemic are urgently needed.

[PMID: 33854448 PMCID: PMC8039125 DOI: 10.3389/fpsyt.2021.611069] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Accepted: 03/08/2021] [Indexed: 12/29/2022] Open
Abstract
Although self-disturbances (SD) are considered to be a core psychopathological feature of schizophrenia spectrum disorders, there is still insufficient empirical data on the mechanisms underlying these anomalous self-experiences. The aim of the present study was to test a hypothesized model in which cognitive biases and exposure to traumatic life events are related to the frequency of SD which, in turn, contribute to the frequency of psychotic-like experiences (PLEs). Our sample consisted of 193 Polish young adults from the general population (111 females; 18-35 years of age, M = 25.36, SD = 4.69) who experience frequent PLEs. Participants were interviewed for PLEs, SD and social functioning as well as completed self-reported questionnaires and behavioral tasks that measure cognitive biases (e.g., safety behaviors, attention to threat, external attribution, jumping to conclusion, source monitoring, overperceptualization). The model was tested using path analysis with structural equation modeling. All of the hypothesized relationships were statistically significant and our model fit the data well [χ2(23) = 31.201; p = 0.118; RMSEA = 0.043 (90% CI = 0.00-0.078), CFI = 0.985, SRMR = 0.041, TLI = 0.976]. The results revealed a significant indirect effect of traumatic life events on PLEs through SD and self-reported cognitive biases. However, performance-based cognitive biases measured with three behavioral tasks were unrelated to SD and PLEs. The frequency of SD explained a substantial part (43.1%) of the variance in PLEs. Further studies with longitudinal designs and clinical samples are required to verify the predictive value of the model.

Abstract
AIM The at-risk mental state (ARMS) allows clinicians to identify individuals who have an increased risk of developing psychosis. At present, most screening for psychosis-risk is carried out within help-seeking populations; however, screening within educational settings may allow clinicians to identify individuals at-risk earlier and to increase the rate of detection. This review aimed to examine screening for the ARMS in educational settings, with the key questions: what screening tools have been used in educational settings, can screening in educational settings detect individuals with ARMS, what threshold scores in screening tools indicate a positive screen in educational settings, are there comorbid mental health conditions associated with the ARMS in educational settings? METHODS Searches were carried out in PsycINFO, MEDLINE, EMBASE, Scopus and Web of Science and reference lists of included articles searched. Results were summarized using narrative synthesis. RESULTS Nine papers were included for narrative synthesis. A variety of screening tools have been used when screening for the ARMS in educational settings. The majority of studies have been conducted in schools. The prevalence of the ARMS reported in ranges from 1% to 8%. CONCLUSIONS The ARMS indicates the presence of distressing symptoms for which intervention may be beneficial. Screening programmes within educational settings may allow outreach for prodromal symptoms at an earlier stage than clinical settings currently provided for.

Abstract
In this study, entrepreneurship education was explored from the perspective of the combination of psychology and literary ethics, with the purpose of studying the entrepreneurial behavior of Chinese American college students and promoting the development of entrepreneurship education. Based on the analysis of self-efficacy, the correlations among entrepreneurial intention, entrepreneurship education, and entrepreneurial efficacy of the research samples were analyzed. First, through the questionnaire design, the research samples and the measurement scales of each research variable were determined, and the survey results and the reliability of the scale were analyzed and tested. Second, based on the variance analysis and regression analysis methods, a descriptive statistical analysis was performed on the correlations among entrepreneurship education, entrepreneurial intentions, and entrepreneurial efficacy among Chinese American college students. Finally, the idea of literary ethics was integrated into entrepreneurship education, entrepreneurial intentions, and entrepreneurial self-efficacy, and the correlation structure model was constructed. The intermediary role of entrepreneurial efficacy in entrepreneurship education and entrepreneurial intention was tested. In addition, the individual gender and family entrepreneurial behaviors were considered. The results show that the valid response rate of the questionnaire, is satisfactory at, 96.49%; the reliability and validity of the scales of the research variables are satisfactory; the Cronbach’s Alpha reliability coefficient values are all above 0.80; and the fitting results of the confirmatory factors are satisfactory. The regression analysis results show significant correlations among entrepreneurship education, entrepreneurial intentions, and entrepreneurial efficacy among Chinese American college students. Entrepreneurial efficacy has a partially intermediary role in the two dimensions of entrepreneurship education and entrepreneurial intention. Individual gender and family entrepreneurial behaviors have moderating effects, on the entrepreneurial efficacy levels of college entrepreneurs. From the perspectives of psychology and literary ethics, the above results have positive effects on the development of entrepreneurship education.

Abstract
OBJECTIVE To investigate the reliability and validity of the Korean version of the Community Assessment of Psychic Experiences-15 item positive scale (CAPE-15) in college students. METHODS This study had two stages: initial screening with self-report questionnaires including the CAPE-15, and semi-structured interviews to investigate the instrument's diagnostic validity. The initial screening involved 1,749 college students. The modified Korean version of Prodromal Questionnaire-16 item (mKPQ-16) was also administered. The criteria for ultra-high risk (UHR) of psychosis in the Comprehensive Assessment of At-Risk Mental States (CAARMS) were the gold standard for diagnosis. RESULTS Twelve of the interviewed subjects met the CAARMS criteria for UHR of psychosis. The area under the receiver operating characteristic curve was highest (0.936) for the CAPE-15 distress score (p<0.001). The use of 6 as the cutoff for the CAPE-15 distress score resulted in the best balance of sensitivity (91.7%) and specificity (85.2%), with a favorable positive predictive value of 32.4%. The coefficients of correlation between the CAPE-15 and mKPQ-16 were significant. CONCLUSION The Korean version of the CAPE-15 is a good instrument for screening for psychosis risk in collegiate settings. The validation of this scale could contribute to the early identification of psychosis in the Korean community.

Abstract
OBJECTIVE In this study, we examined the reliability and validity of the Korean version of the Prodromal Questionnaire-Brief (PQ-B), a self-report screening instrument for clinical high risk for psychosis (CHR). METHODS A total of 3,400 middle, high school and college students participated, and 261 subjects with a PQ-B total score ≥3 completed both the PQ-B and the Structured Interview for Prodromal Syndromes (SIPS). Receiver operating characteristic (ROC) curves were used to examine the psychometric properties of the PQ-B. RESULTS A cut-off of 7 for the PQ-B total score and a cut-off of 22 for the PQ-B distress score showed the best balance of sensitivity (72.2%, 77.8%) and specificity (71.4%, 75.0%). CONCLUSION The Korean version of the PQ-B showed good reliability and validity for predicting prodromal risk symptoms in the community population.

Abstract
Objectives: Psychotic-like experiences (PLEs) and problematic internet use (PIU) are common in adolescents. However, little is known about the association between PLEs and PIU among adolescents. The present study examined the associations between PLEs and PIU and negative life events among adolescents. Methods: In total, 1,678 adolescents attending high school were recruited for a cross-sectional survey. They completed self-reported assessments of PLEs using the Prodromal Questionnaire-16 (PQ-16) and measures of depression, anxiety, self-esteem, internet use, and negative life events using the Center for Epidemiological Studies Depression Scale (CES-D), the State-Trait Anxiety Inventory (STAI), the Rosenberg Self-Esteem Scale (RSES), the Korean Scale for Internet Addiction (K-scale), and the Lifetime Incidence of Traumatic Events for Children (LITE-C), including cybersexual harassment and school violence. Results: A total of 1,239 subjects (73.8%) scored at least 1 on the PQ-16. The mean total and distress PQ-16 scores were significantly higher in students who used mental health services. The total and distress prodromal questionnaire-16 (PQ-16) scores were positively correlated with the CES-D, STAI-S, STAI-T, LITE-C, and K-scale scores but negatively correlated with the RSES score. Hierarchical linear regression analysis revealed that PLEs were significantly associated with a high K-scale score and the incidence of negative life events, such as LITE-C, cybersexual harassment, and bully-victims. Conclusion: Our results demonstrate that PIU and negative life experiences were significantly associated with PLEs in adolescents. Assessment and therapeutic intervention with regard to internet use as a coping strategy for stress are needed to prevent the development of clinical psychotic symptoms.
