ÖZETAmaç: Bu çalışmada amaç Bipolar Prodrom Belirti Tarama Ölçeği Türkçe sürümünün güvenilirlik ve geçerliliğini ortaya koymaktır.Yöntem: Araştırma Celal Bayar Üniversitesi 1. sınıf öğrencileriyle yü-rütülen bipolar bozukluğun epidemiyolojisine dair bir çalışmanın denekleriyle yürütülmüştür. Buna göre bipolar bozukluk saptanan 30 ve sağlıklı kontrol grubu olarak 122 gönüllü çalışmanın örneklem grubunu oluşturmuştur. Birlikte geçerlilik amacıyla Hipomani Soru Listesi-32-Yenilenmiş Sürümü uygulanmıştır. İstatistiksel değerlendirmede iç tutarlılık katsayısı, madde-toplam puan bağıntı katsayıları, açıklayıcı faktör analizi, diğer ölçekle bağıntı ve ROC eğrisi hesaplanmıştır. SUMMARY Reliability and Validity Study of the Turkish Version of Bipolar Prodrome Symptom ScaleObjective: In this study, it is aimed to evaluate the reliability and validity of the Turkish version of Bipolar Prodrome Symptom Scale. Method:The study was carried out with subjects who participated the study on the epidemiology of bipolar disorder among the students in the 1st grade of Celal Bayar University. The sample consisted of 30 volunteers diagnosed as bipolar disorder and 122 healthy controls. For concurrent validity, Hypomania Checklist-32-Revised was used. In the statistical analysis, internal consistency coefficient, item-total score correlation coefficients, exploratory factor analysis, correlation with concurrent scale and ROC curve were calculated. Results:Translation into Turkish and back-translation into English of were performed and thus the semantic harmony of the scale was obtained. In the internal consistency, Cronbach alpha coefficient was between 0,969-0,979 and item-total score correlations were between 0,767-0,929 and 0,725-0,890. In factor analysis, for the severity subscale a one-factor solution representing 78,9% of the variance and for the frequency subscale one-factor solution representing 71,7% of the solution are obtained. Correlation of Bipolar Prodrome Symptom Scale with Hypomania Checklist-32-Revised was r=0,513 and 0,530. In the ROC analysis, area under the curve was 0,977 and 0,999. The scale discriminates well between the bipolar group and healthy control group.Conclusion: Bipolar Prodrome Symptom Scale developed for screening hypomania is reported to be reliable and valid in Turkish.

Objectives: Schizophrenia is a disorder with different clinical features. Schizophrenia may start insidiously and slow and go on for many years. But the negative symptoms and deficiency symptoms leading to social deterioration may come to the forefront. All these factors are taken into consideration, our aim in this study was to examine the demographic and clinical effects of symptoms on schizophrenic patients who have not yet been treated. Methods: Eighty patients who were admitted to the Ankara Numune Training and Research Hospital Psychiatry Outpatient Clinic, who did not have any previous antipsychotic medications and who did not use medications at the time of admission and who met the criteria for schizophrenia according to the DSM-5. Sociodemografic Data Form and the PANSS scale were used to assess the clinical status of the patients. Results: When the demographic characteristics of the participants were examined, 33 (41.2%) were female and 47 (58.8%) were male. The mean age of the patients was 31.08±9.37; mean education year was 8.76±3.53. When the patients participating in the study were evaluated in terms of gender, marital status, working status, smoking status, and family history, no statistical differences were found between the groups in terms of their PANSS scores (p>0.05). However, the PANSS Negative subscale scores (p<.001), general psychopathology scores (p=0.006), and total PANSS scores (p=0.003) were statistically significantly different between the three groups when the patients were untreated for 0-1 years, 1-5 years, and 5 years. Conclusions: In this study none of the sociodemographic factors we assessed had any effect on symptom severity. However, there are different results in the literature regarding gender, age, marital status and working status. Besides, it has been determined that the most important clinical manifestation in our study is the period without treatment. Further studies should identify demographic and clinical features that affect schizophrenic symptom changes.
