S52 E-Poster Presentation / European Psychiatry 56S (2019) S3–S321Methods.– A retrospective study of 17 adolescent patients referredto the department of child and adolescent psychiatry at MongiSlim hospital in Tunis (Tunisia). The DSM-5 OCD criteria and theYale–Brown Obsessive Compulsive Scale were used.Results.– The mean age was 14 years old. The sex ratio was 0.5.A triggering factor was found in 53% of the cases. Contamina-tion was the most prevalent obsession, followed by death fear.Washing/cleaning was the most common compulsion followed bychecking and ordering rituals. Comorbidity was present in 64.7%of the patients, forty-seven percent of referred adolescents had adepressive disorder and 23.5% had an anxiety disorder. Seventypercent of the subjects had an important impact on their sociallife and school results, family conflicts, social withdrawal and poorschool performance were the most common consequences. Forty-one percent of the subjects had a pharmacological treatment anda cognitive behavioral therapy, forty-one percent had only psy-chotherapy and 18% had only pharmacotherapy.Conclusions.– Obsessive-compulsive disorder is a distressful dis-order that has a serious impact on adolescent’s quality of life.Depressive and anxiety disorders are very commonly associeted.Disclosure of interest.– The authors have not supplied a conflict ofinterest statement.E-Poster Presentation: Classification of mentaldisorders / Research Methodology - Part IE-PP0227Diagnostic instability in psychiatryB. Côrte-Real1*, P. Câmara Pestana1,2, T. Duarte1,2, A. BonitoFerreira1,21 Santa Maria’s University Hospital – Lisbon’s North Hospital Center,Psychiatry and Mental Health, Lisbon, Portugal; 2 Faculty ofMedicine- University of Lisbon, Psychiatry, Lisbon, Portugal* Corresponding author.Background and aims.– Diagnostic instability is a measure to whichpsychiatric diagnoses change over time in the same patient. Sincepsychiatric diagnostic categories are developed without biologicalmarkers, the diagnostic process is less reliable in psychiatry thanin other fields of medicine.The authors aim to study changes in psychiatric diagnoses and thefactors involved.Methods.– Nonsystematic review of the literature with the follow-ing search terms: “diagnostic instability”, “diagnostic accuracy”,“overdiagnosis”, “misdiagnosis” and “diagnostic error”.Results.– The overall mobility of diagnoses ranged from 27 to40%. For most studies, the diagnosis with greater instabilitywas schizoaffective disorder, with some authors even defend-ing its elimination from the diagnostic classification. On theother hand, the most stable diagnosis over time is schizophrenia(mean stability: 90%). The greatest diagnostic shifts move towardsschizophrenia with the existence of negative symptoms as the maincontributing factor. Bipolar disorder (BD) revealed the most vari-able results depending on the study. In some, underdiagnosis isthe issue, especially when the first episode is depressive or whenpsychotic symptoms are present. In fact, approximately 61,5% ofbipolar patients with psychotic symptoms received a first diagno-sis different from BD. BD may also be overdiagnosed, particularlyin the presence of personality and substance use disorders.Conclusions.– In the absence of biological markers, longitudinal val-idation through a long-term follow-up is necessary for accuratediagnostic ascertainment. It is believed that family or genetic stud-ies will become a more reliable tool in error detection as well.Disclosure of interest.– The authors have not supplied a conflict ofinterest statement.E-PP0228Gaming behavior in portugueseuniversity studentsA.R. Dores1,2*, A. Geraldo3, F. Barbosa21 School of Health- Polytechnic Institute of Porto, Human and SocialSciences, Porto, Portugal; 2 Faculty of Psychology and EducationalSciences of University of Porto, Laboratory of Neuropsychophysiology,Porto, Portugal; 3 School of Health- Polytechnic Institute of Porto-Faculty of Psychology and Educational Sciences of University of Porto,Human and Social Sciences- Laboratory of Neuropsychophysiology,Porto, Portugal* Corresponding author.Background and aims.– Gaming behaviors have been receivingincreased attention from the scientific community in recent years.This phenomenon has accompanied the easier access to betting andcasino-like games, and the establishment of online gaming as animportant recreational activity, particularly in western societies.Considering the impact that the potential addictive power of gamescan have in human health and well-being, it seems important tobetter know and understand this phenomena.We aimed to study gaming behaviors in Portuguese univer-sity students. Additionally, we explored the predictive power ofsociodemographic and academic variables (age, years of educa-tion, years of registration and number of withholdings) in gamingbehavior.Methods.– The study comprised 908 university students(Mage = 22.07, SD = 7.08), 525 females (57.8%). All participantsfilled online the Gaming Addiction Scale (Lemmens, Valkenburg,& Peter, 2009; Portuguese version of Baptista, Viegas, & Gradil,2010).Results.– These results are consistent with the literature, highlight-ing the increase in gaming behaviors among youths in the last years.Besides, it were found positive correlations among pathologicalgaming and some sociodemographic variables.Conclusions.– The above-mentioned results shed light on the ques-tion “Why do some individuals undergo this transition fromrecreational to addictive gambling/gaming behaviors?”, as it allowsto reflect on the influence of some moderating variables. In futurestudies, it seems important to explore the impact of the GamingDisorder in the quality of life of gamers.Disclosure of interest.– The authors have not supplied a conflict ofinterest statement.E-PP0230Clinical practice in coding usingICD-10 as a source of inspirations forthe implementation of ICD-11. Aqualitative analysisW. KosmowskiNicolaus Copernicus University, Department of Psychiatry, Bydgoszcz,PolandBackground and aims.– ICD-10 has been used in Poland since 1996.The aim of this study is to compare clinical descriptions, writtendiagnoses and ICD-10 codes used by professionals. Even a per-fect diagnostic system can be used in proper or improper way.The results may be beneficial for the preparation of doctors andstatisticians for the changes forced by ICD-11.Methods.– 500 medical histories, containing referrals to psychiatriccare or discharge summaries from both psychiatric and non-psychiatric wards, were randomly selected from the psychiatricoutpatient clinic records from years 2017–2018. All codes wereassigned by doctors.A competent psychiatrist compared codes with medical data.Results.– The types of errors were as follow. Different namesthan the official ICD-10 translation were used to diagnose certaindisorders. General codes were implemented to describe specific
