Quantitative analysis of the EEG (q-EEG) in patients with obsessive compulsive disorder (OCD) showed a decreased beta and an increased theta power at frontotemporal regions. The patients who had higher scores in doubting test (Maudsley Obsessive Compulsive Questionnaire) and more severely ill patients shared similar q-EEG features. The relative theta powers were significantly increased and alpha powers were significantly decreased in these patients, particularly in the frontotemporal region. It was suggested that the q-EEG may be useful in investigating the OCD patients with heterogeneous characteristics.

ÖZET Amaç: Bu çalışmada DSM-5 Bozuklukları için Yapılandırılmış Klinik Görüşme-Klinisyen Versiyonunun (SCID-5/CV) Türkçeye uyarlanması ve güvenilirliği araştırılmıştır.Yöntem: Araştırma iki üniversite hastanesinde ayaktan ya da yatarak tedavi alan 185 hastayla yürütülmüştür. SCID-5/ CV(KlinisyenVersiyonu)'nin özellikleri ve kullanımı konusunda eğitim toplantıları yapılması sonrasında, bir psikiyatrist görüşmeci iken diğeri gözlemci; diğer psikiyatrist görüşmeci iken diğeri gözlemci olacak şekilde uygulanmıştır. Görüşmeciler arası güvenilirlik araştırılmış ve Cohen kappa katsayısı hesaplanarak istatistiksel değerlendirme yapılmıştır. Bulgular:Hastaların yaş ortalaması 37,2±13,5'ti ve %55,7'si kadındı, %38,9'unun eğitim durumu yükseköğretim, %23,8'inin lise, %33'ünün ilköğretim, %1,6'sı okuryazar ve %2,7'si okuryazar değildi. Kappa katsayısının, şizofreni (κ=0,93), bipolar bozukluk (κ=0,96), major depresif bozukluk (κ=0,89), distimik bozukluk (κ=0,82), alkol kullanım bozukluğu (κ=0,96), panik bozukluğu (κ=0,84), agorafobi (κ=0,85), toplumsal kaygı bozukluğu (κ=0,95), yaygın anksiyete bozukluğu (κ=0,89), obsesif kompulsif bozukluk (κ=0,87), travma sonrası stres bozukluğu (κ=0,89), erişkin dikkat eksikliği ve hiperaktivite bozukluğu (κ=1,00), özgül fobi (κ=0,82) için mükemmel uyumu yansıttığı bulunmuş; bedensel belirti bozukluğu (κ=0,65) ve uyum bozukluğu (κ=0,78) için çok iyi uyumu yansıttığı bulunmuştur.Sonuç: Geçmiş SCID versiyonlarına benzer şekilde kappa katsayısı oldukça yüksek bulunmuştur ve hepsi istatistiksel olarak anlamlıdır. SCID-5/CV'nin Türkçe versiyonu hem günlük klinik pratikte hem de klinik çalışmalarda güvenilir bir şekilde kullanılabilir.Objective: In this study, we aimed to adapt the Structured Clinical Interview for DSM-5-ClinicianVersion into Turkish and to demonstrate its reliability. Method:A total of 185 patients, both inpatient and outpatient, from two different university hospitals were included. Training sessions on the features and use of SCID-5/CV were held before the data collection. During the study, in order to test the diagnostic agreement and accuracy, two psychiatrists remained present at the evaluation of each participant; alternatively being interviewer and the observer. Cohen's kappa coefficient for inter-rater reliability was calculated for every diagnostic category. Results:The patient group had a mean age of 37.2 (±13.5) years and 55.7% were female. The education status was as follows: 2.7% were illiterate, 1.7% literate with no primary education, 33% had primary education, 23.8% had secondary education and 38.9% had higher education. The calculated kappa value showed excellent agreement for schizophrenia (κ=0.93), bipolar disorder (κ=0.96), major depressive disorder (κ=0.89), dysthymic disorder (κ=0.82), alcohol use disorder (κ=0.96), panic disorder (κ=0.84), agoraphobia (κ=0.85), social anxiety disorder (κ=0.95), generalized anxiety disorder (κ=0.89), obsessive compulsive disorder (κ=0.87), posttraumatic stress disorder (κ=0.89), adult attention deficit and hyperactivity di...

A significant proportion of cancer patients experience psychiatric morbidity. Potential predictors of psychiatric morbidity include patient disease-related factors and factors relating to the patient's environment. The aim of this study was to investigate the prevalence of psychiatric morbidity and the relationship between the clinical or personal factors, especially psychiatric morbidity, and awareness of cancer diagnosis among a group of Turkish cancer patients. A total of 117 cancer patients were assessed using the Structured Clinical Interview for DSM-IV (SCID), the Hospital and Anxiety Depression Scale (HADS) and the General Health Questionnaire (GHQ). Of these patients, 30% had a psychiatric diagnosis. Adjustment disorders comprised most of the psychiatric diagnoses. Awareness of the diagnosis of cancer, history of previous psychiatric disorders, pain and stress factors were correlated with psychiatric morbidity. Of the 117 patients, 64 (54.7%) were unaware of the diagnosis of cancer. Most of the patients (67.9%) who were considered to be aware of the cancer diagnosis stated that they had guessed their illness from the treatment process or drug adverse effects. Psychiatric morbidity was significantly higher in the patients who knew that they had a cancer diagnosis (P=0.03). These findings suggest that the awareness of cancer diagnosis is related to the presence of psychiatric morbidity. In particular, the understanding of the diagnosis indirectly may be stressful to the patient because it arouses suspicion about the cancer and treatment, and consequently can lead to psychiatric disturbance. In Turkey honest disclosure of the true diagnosis is still not common for cancer patients and it seems to be essential to improve this situation.

This study aimed to investigate the clinical features of obsessive-compulsive disorder (OCD) and the possible association between obsessive-compulsive symptoms and culture-related characteristics in a sample of Turkish patients with OCD. We studied 141 patients with OCD (according to DSM-IV criteria) consecutively admitted to our outpatient clinic during the period from February 1998 to December 2003. We used the Turkish version of the Structured Clinical Interview for DSM-IV (SCID) to interview all patients, and the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) to assess obsessive-compulsive symptoms and severity. The onset of OCD symptoms was earlier in males. Major depression was the most common comorbid disorder (30.5%). The most commonly occurring obsessions were contamination (56.7%), aggression (48.9%), and somatic (24.1%), followed by religious (19.9%), symmetry (18.4%), and sexual imagery (15.6%). Symmetry and sexual obsessions, and checking compulsions and rituals, tended to be more common in male patients. Dirt and contamination obsessions and washing compulsions were slightly more common in females. The vast majority of patients with religious obsessions (83%) and half of the patients with sexual obsessions had compulsions that included religious practices. Also, patients with sexual and religious obsessions had delayed seeking professional help.
