The Assessment of Obsessive-Compulsive Symptoms
(Turkiye Sinir ve Ruh Sagligi dernegi, 2005) Besiroglu, L; Agargün, MY; Boysan, M; Eryonucu, B; Gülec, M; Selvi, Y
Objective: We examined the reliability and validity of the 60-and 41-item versions of the Padua Inventory (PI and PI-R) which were developed to assess the frequency and severity of obsessive-compulsive symptoms, in a Turkish population. Method: The sample consisted of 43 OCD patients, 30 non-OCD patients with other anxiety disorders, 30 nonobsessional depressed patients, 76 healthy adults, and 181 undergraduate students. We investigated internal consistency, test-retest reliability, and factor structure, concurrent and discriminant validity. Results: Psychometric analyses showed that both the original PI and PI-R had a high internal consistency and test-retest reliability. While principal factor analysis of the 41 items revealed six factors that are consistent with the PI-R, the factor structure of the original scale was not confirmed. All the subcales and total scores for both instruments were significantly correlated with the Yale-Brown scores except for the impulses subscale. There were significant differences between OCD patients and nonclinical samples in all total and subscale scores for both instruments. OCD patients scored significantly higher on the total, contamination/washing and checking subscales for both instruments than nonobsessional anxious, and depressed patients. While OCD patients scored significantly higher on the PI-R rumination scale than nonobsessional anxious patients, their PI impaired control subscale score was not different from that of the other clinical groups. Conclusions: The Turkish version of the PI has appropriate reliability and validity for assessing the frequency and severity of obsessive-compulsive symptoms.

Clinical Importance of Nightmare Disorder in Patients With Dissociative Disorders
(Wiley, 2003) Agargun, MY; Kara, H; Özer, ÖA; Selvi, Y; Kiran, Ü; Özer, B
In the present study the prevalence of nightmare disorder (ND) was examined in patients with dissociative disorders (DD), and comparison was made between those with ND and those without nightmares in terms of clinical characteristics. The 30 patients with DD (5 male and 25 female) were recruited over 12 months in the Yuzuncu Yil University Research Hospital Department of Psychiatry. The subjects were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (4th edn) criteria for ND. The Dissociative Experiences Scale, Beck Depression Inventory, and a semistructured interview schedule for childhood traumatic events were administered to the subjects. A 57% prevalence of ND was found among patients with DD. Among patients with DD, those with ND had a higher rate of self-mutilative behavior, a history of suicide attempt in the last year, and comorbidity with borderline personality disorder than those without ND. Nightmares or dreams should be considered in the therapy of DD patients.
Nightmares and Dissociative Experiences
(Wiley, 2003) Agargun, MY; Kara, H; Özer, ÖA; Selvi, Y; Kiran, Ü; Kiran, S
In order to examine the co-occurrence of nightmares with dissociative experiences in the adolescent population and to demonstrate the impact of childhood traumatic events in this association, 292 undergraduate students were interviewed for childhood traumatic events. The Van Dream Anxiety Scale (VDAS) and Dissociative Experiences Scale (DES) were also administered to the subjects. For nightmares a 7.5% prevalence of 'often' and a 58.2% prevalence of 'sometimes' was found for college students. Nightmare prevalence was higher in women than in men. The rate of childhood traumatic experiences was higher in nightmare sufferers than in those who did not have nightmares. The subjects who had undergone physical and sexual abuse had higher VDAS global scores and item scores. When the DES scores of the subjects with nightmares were compared with that of those who had never reported nightmares, the subjects with nightmares had significantly higher scores on DES. The DES scores were also negatively correlated with duration of nightmares in subjects who had childhood traumatic experiences. These findings suggest that the subjects with childhood traumatic events failed to psychologically integrate their traumatic experiences and used dissociation as a coping strategy.
The Prevalence of Parasomnias in Preadolescent School-Aged Children: a Turkish Sample
(Oxford Univ Press inc, 2004) Agargun, MY; Cilli, AS; Sener, S; Bilici, M; Ozer, OA; Selvi, Y; Karacan, E
Study Objectives: To survey the prevalence of parasomnias in a population of children aged 7 to 11 years and to determine whether parasomnias are associated with medical and neurobehavioral properties. Design: Parents and children completed a pediatric sleep questionnaire that contains 27 items developed by the authors to assess parasomnias in children. Parents and children were also interviewed about the children's medical and sociofamilial history, schooling, psychological difficulties, medication intake, and the history of psychomotor and psychosocial development. Setting: NA Participants: 971 preadolescent school-aged children from 4 locations in Turkey participated in the study. Results: We found a 14.4% prevalence of parasomnia in preadolescent school-aged children. Almost every sixth child had about at least 1 parasomnia. When we examined parasomnias separately, bruxism, nocturnal enuresis, and night terrors were the most common parasomnias among both girls and boys. The prevalence of parasomnias was higher in the 9- and 10-year-old age groups than in the other age groups. Girls and boys did not differ. Children with parasomnias had higher rates of past physical illness, delays in toilet raining, behavior disturbances, adjustment problems, and learning difficulties. Conclusions: These results suggest that the prevalence of parasomnias was high in the 9- and 10-year-old age groups. Parasomnias are associated with a history of physical illness and neurobehavioral abnormalities.
Serum Lipid Levels in Patients With Dissociative Disorder
(Amer Psychiatric Publishing, inc, 2004) Agargun, MY; Özer, OA; Kara, F; Sekeroglu, R; Selvi, Y; Eryonucu, B
Objective: There may be an association between a low serum cholesterol level and dissociative disorders. Method: The subjects of the study were 16 patients with dissociative disorder and 16 normal comparison subjects (two men and 14 women in each group). Total cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein, and very low density lipoprotein levels were compared. Results: Patients with dissociative disorders had lower serum triglyceride, total cholesterol, low-density lipoprotein, and very low density lipoprotein levels than normal comparison subjects. Conclusions: Low serum lipid concentrations may be related to a high incidence of self-injurious behaviors and borderline features in patients with dissociative disorders.
Serum Lipid Levels, Suicidality, and Panic Disorder
(W B Saunders Co, 2004) Özer, ÖA; Kutanis, R; Agargun, MY; Besiroglu, L; Bal, AC; Selvi, Y; Kara, H
Although the effects of serum total cholesterol and other lipids have been implicated as a predictor of suicidal behavior in major depression, the role of cholesterol level on suicide risk for panic disorder patients is not considered as a biological marker in the literature. In this study, we examined the relationship of suicidality with serum cholesterol concentration in panic disorder. The subjects of the study were 10 suicidal panic disorder patients, 19 nonsuicidal panic disorder patients, and 15 normal control subjects. The suicidal patients with panic disorder had lower serum total cholesterol and low-density lipoprotein (LDL) levels than normal control subjects. These findings suggest that there may be an association between suicidality and low serum cholesterol levels in panic disorder. We also discuss the possible role of serotonin in the brain in the relationship of suicidal behavior or ideation with low cholesterol concentration in panic disorder patients, and 15 normal control subjects. Thesuicidal patients with panic disorder had lower serum total cholesterol and low-density lipoprotein (LDL) levels than normal control subjects. These findings suggest that there may be an association between suicidality and low serum cholesterol levels in panic disorder. We also discuss the possible role of serotonin in the brain in the relationship of suicidal behavior or ideation with low cholesterol concentration in panic disorder. (C) 2004 Elsevier Inc.

Sleep-Related Violence and Low Serum Cholesterol
(Blackwell Publishing Asia, 2002) Agargun, MY; Sekeroglu, MR; Kara, H; Özer, ÖA; Tombul, T; Kiran, Ü; Selvi, Y
To examine whether there is a relationship between serum cholesterol level and sleep-related violence, we evaluated 15 patients with violent behavior during sleep (VBS) and 15 normal control subjects. The patient and control groups were matched for sex, age, and weight. There were 13 women and two men in each group. The patients with VBS had lower serum total cholesterol, triglyceride, and low-density lipoprotein levels than the healthy subjects. Low cholesterol may effect serotonergic neuronal activity and some types of 5-HT receptors, then may be related to violent behavior during sleep.
