The 16\u2010item Prodromal Questionnaire (PQ\u201016) is a screening tool for evaluating those at risk of developing a psychotic disorder. The study aimed to evaluate the psychometric properties of the Latvian version of the PQ\u201016 in a sample of help\u2010seeking adolescents referred for diagnostic assessment and look for possible associated socio\u2010demographic and health\u2010related factors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cross\u2010sectional study included patients admitted for evaluation between November 2022 and February 2023 in Riga's Children's Clinical University Hospital Child Psychiatry clinic. The data were collected during outpatient consultations by mental health professionals. We used the Latvian translation of PQ\u201016 and the socio\u2010demographic and health\u2010related factors questionnaire. Data were analysed with IBM SPSS 28; the scale's diagnostic accuracy and internal validity were examined.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The study involved 107 adolescents aged 12% to 17%, 80.5% female, with a mean age of 14.98 (CI 14.70\u201315.26). Socio\u2010demographic data and health\u2010related variables did not significantly differ between the sexes (<jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05). The Latvian PQ\u201016 demonstrated excellent internal reliability with a Cronbach's alpha of 0.890. All 16 items were found to be valid with <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001. A significant number of participants (73.8%) scored above the current cut\u2010off of \u2265\u20096 with a mean of 9.17 (95% CI 8.41\u20139.93). Certain socio\u2010demographic factors, such as female gender (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), fair school performance (<jats:italic>p<\/jats:italic>\u2009=\u20090.048) and recent changes in school performance (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), demonstrated a significant association with higher scores. Additionally, there were found significant associations between positive screening and health\u2010related factors such as obstetric complications (<jats:italic>p<\/jats:italic>\u2009=\u20090.044), smoking (<jats:italic>p<\/jats:italic>\u2009=\u20090.002), alcohol consumption (<jats:italic>p<\/jats:italic>\u2009=\u20090.021), history of bullying in school (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) and emotional abuse at home (<jats:italic>p<\/jats:italic>\u2009=\u20090.011).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Latvian translation of PQ\u201016 showed high internal reliability and validity levels. Positive PQ\u201016 screening was associated with female gender, worsened school performance, obstetric complications, substance abuse and experienced emotional violence. The average score of 9.17 positive answers and 73.8% of participants screening positive for attenuated psychotic symptoms is significantly higher than in recent studies under similar
