Article Associations Between Career Decision-Making Difficulties, Maladaptive Limitedness Schemas, Sleep Quality, and Circadian Preferences Among Turkish College Students(Kure Iletisim Grubu A.S., 2016) Boysan, M.; Kagan, M.The present study investigated the relations among decision-making difficulties, maladaptive limitedness schemas, sleep quality, and circadian preferences in a sample of 311 Turkish college students. As expected, the associations between career decision-making difficulties, as measured by the Career Decision-Making Difficulties Questionnaire (CDDQ), and poor sleep quality were significant, but the connections were small. Pearson correlations of poor sleep quality with career decision-making difficulties, including Lack of Information and Difficulties related to Inconsistent Information sub-scales, and CDDQ total scores, ranged from 0.19 to 0.20. On the other hand, in the multiple regression analyses we found that dysfunctional thinking, as measured by the Limitedness Schemas Questionnaire (LSQ), significantly contributed to all three sub-scales and total scores of the CDDQ. Implications of these findings are discussed.Article Associations Between Circadian Preferences, Sleep Quality, Dissociation, Post-Traumatic Cognitions, and Post-Traumatic Stress Disorder (Ptsd) Among Incarcerated Offenders(Kure Iletisim Grubu A.S., 2019) Acar, O.F.; Ogulmus, S.; Boysan, M.The aim of this study was to explore whether DSM-5 posttraumatic stress disorder (PTSD) dissociative subtype could be differentiated from non-dissociative PTSD caseness in sleep disturbances, circadian preferences, and posttraumatic cognitions. We also investigated associations of dissociation, sleep quality, insomnia, circadian preferences, and traumarelated negative cognitions with DSM-5 PTSD caseness among prisoners. Data from 399 volunteers (mean age: 34.54±9.93 years) were collected. Using the symptoms clusters measured by the PTSD Checklist for DSM-5 (PCL-5) and Dissociative Experiences Scale (DES), the participants were classified into four subgroups: no dissociation or PTSD, pure dissociative, pure PTSD, and dissociative PTSD. Differences in scale scores across four groups were evaluated using one-way analysis of variance. Logistic regression analysis was utilized to determine predictors of DSM-5 PTSD caseness. Participants with dissociative PTSD reported significantly greater posttraumatic stress reactions in terms of PTSD and dissociative symptomatology, greater number of prior trauma exposure, greater scores on posttraumatic negative cognitions, and a tendency to have eveningness diurnal preferences in comparison to those prisoners classified into other three subgroups (no dissociation or PTSD, pure dissociative, and pure PTSD). However, sleep disturbances in terms of insomnia and poor sleep quality were found to be pronounced among prisoners with PTSD irrespective of levels of dissociation. Dissociative symptomatology, insomnia and poor sleep quality significantly contributed to probable PTSD caseness. Dissociation and sleep disturbances appear to be hallmark for PTSD among prisoners. © 2019 Kure Iletisim Grubu A.S..

The first aim of the study was to investigate psychometric properties of the Turkish version of the Chen Internet Addiction Scale (CIAS). Second, we explored the relations between Internet Addiction, Attachment Style Emotion Regulation, Depression and Anxiety among college students. A total of 754 college students participated in the study. The CIAS, Young Internet Addiction Test (YIAT), Experiences in Close Relationship-Revised (ECR-R), Difficulties in Emotional Regulation Scale (DERS), Center for Epidemiological Studies Depression Scale (CES-D), Beck Anxiety Inventory (BAI), and WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) were administered in the study. The CIAS was subjected to confirmatory factor analysis. The associations between Internet addiction, attachment styles, difficulty in emotion regulation, anxiety and depression were evaluated using one-way analysis of variance and logistic regression analysis. The signal detection analysis showed that a cut value of 64 for the CIAS, with diagnostic accuracy of 97.1% and a cut value of 40 for the YIAT, with diagnostic accuracy of 86.9% were evaluated to be best diagnostic cutoff points. Considering univariate relationships between variables of interest, fearful and preoccupied attachment were significantly associated with pathological Internet use. Logistic regression analyses demonstrated that being male, difficulties in emotional regulation, anxiety and depression statistically significantly contributed to the risk for development of Internet addiction. Internet addiction as indexed by the CIAS cutoff is a highly debilitating mental disorder. © 2019 Kure Iletisim Grubu A.S.

The paper explored the efficiency of the eye movement desensitization and reprocessing (EMDR) therapy in SSD. The current investigation is a clinical trial investigating the effectiveness of eye movement desensitization (EMDR) therapy in the treatment of 31 first-diagnosed SSD patients in comparison to age, education and marital status matched 31-first-diagnosed SSD patients who received duloxetine over a 6-week course of treatment. Somatization subscale of the Symptom Checklist-Revised 90 (SCL-90), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Short Form Health Survey (SF-36) were administered to the participants. EMDR group showed enhanced improvement relative to baseline after 6 weeks of treatment compared to duloxetine group. We concluded that EMDR appears to be a highly promising therapy and should be considered among the first-line interventions in the treatment of SSD.Article The Cyberchondria Severity Scale (Css): Validity and Reliability Study of the Turkish Version(Kure Iletisim Grubu A.S., 2018) Selvi, Y.; Turan, S.G.; Sayin, A.A.; Boysan, M.; Kandeger, A.Objective: Even though the internet is a valuable resource for medical information, it has the potential to increase anxiety, fear or obsessive-compulsive behaviours, particularly among individuals more prone to health related anxiety. Researchers have found that health anxiety, hypochondria, and online health searches are associated with increased anxious symptomatology. The aim of this study is to investigate the psychometric properties of the Turkish version of the Cyberchondria Severity Scale, a measure of online health anxiety. Method: Three hundred thirty-seven university students with an age range of 16-55 were included in the study. The Cyberchondria Severity Scale (CSS), Internet Addiction Test (IAT), Anxiety Sensitivity Inventory-3 (ASI-3), and Health Anxiety Inventory (HAI) were administered to participants. Results: Confirmatory factor analysis revealed that five-factor solution best fit to the data. The overall and subscales of the CSS had excellent internal consistency (Cronbach α = 0.91, for the overall measure, and Cronbach α values ranged from 0.78 to 0.87), with an exception of 'mistruct of medical professional' subscale (Cronbach α = 0.64). The total and subscales of the CSS had generally good convergent validity. Conclusion: The CSS is a newly developed screening tool to assess online health anxiety, and present study demonstrated that the Turkish version of the scale had promising psychometric properties. © 2017 Springer Verlag.

In the face of broad and multifaceted nature of the fact, this work is relatively concise in coverage. Research has indicated significant changes from birth to early-childhood in sleep characteristics in terms of sleep patterns and sleep duration. Children show significant variation in their sleep characteristics as a function of environmental conditions and internal factors such emotional states or physical conditions. The qualitative and quantitative changes in sleep patterns during the early-childhood appear to be occurring in consonant with developmental features and implicated in cognitive, behavioral and emotional development of child. Even though the number of studies in children and adolescents is scarce, the associations between trouble sleep and emotional dysregulation have consistently reported that persist from childhood into early- to mid-adolescence. This review addresses three topics with regards to the importance of sleep in the childhood: i) characteristics of sleep and alteration in these characteristics from infancy to early childhood including development of more complex structures resemble adult sleep and consolidation of sleep wake cycle accompanied by quantitative changes in daytime naps and nighttime sleep; ii) associations between sleep and developmental domains, particularly cognitive and emotional development; and iii) importance of healthy sleep habits and sleep hygiene. The empirical evidence and theoretical considerations within the literature are refined and discussed herein.Article Dissociative Experiences, Childhood Trauma and Alexithymia Among Mothers of Children With Autism Spectrum Disorder(Istanbul Universitesi, 2017) Işık, M.; Yıldırım, A.; Boysan, M.; Murat, D.Objective: Previous studies have consistently pointed out that parents of children with autism spectrum disorder (ASD) had worse mental health relative to parents of normally developing children. In this study, it was aimed to investigate differences in dissociative experiences, childhood trauma and alexithymia between mothers of children with and without ASD. Methods: Thirty-one mothers whose children had a principal diagnosis of ASD and thirty mothers whose had any current psychiatric diagnosis or a history of psychiatric disorder included in the study. The Dissociative Experiences Scale (DES), Toronto Alexithymia Scale (TAS-20), Childhood Trauma Scale (CTQ-28) and Somatoform Dissociation Scale (SDQ) were used as data collection tools. Results: In our study, mothers of children with ASD had more severe dissociative symptomatology, greater depersonalization / derealization, more frequent childhood sexual abuse and physical neglect compared to mothers in control group. However, there was no significant difference in alexithymia levels between two groups. Discussion: The results of our study showed that dissociative symptomatology and childhood traumas should be considered among mothers of children with ASD. © 2018, Istanbul Universitesi.

O.Article Hierarchical Factor Structure of the Turkish Version of the Posttraumatic Growth Inventory in a Normal Population(Gulhane Military Medical Academy, 2012) Kaǧan, M.; Güleç, M.; Boysan, M.; Çavuş, H.AIM: Negative consequences of traumatic experiences, such as depression, anxiety, or dissociative symptoms, etc. have been reported by many researchers. However, it is proposed that stressful events not only lead to poor psychological outcomes but also may trigger positive changes. Several instruments gauging posttraumatic benefits have been developed to examine the effects of factors that may promote positive psychological outcomes in the aftermath of stressful events. The Posttraumatic Growth Inventory (PTGI) is one of the prominent instruments that assess posttraumatic positive changes. In this study we aimed to assess psychometric properties of the Turkish version of the PTGI. METHOD: This study differed to an extent from previous studies concerning the features of the PTGI. We used a dispositional form of the instrument in a sample recruited from high school and university students. Our data were collected from 723 volunteers. 367 subjects were males (50.76%) and 356 subjects were females (49.24%). Also we did not specify any selection criteria in recruiting subjects owing to their adverse life experiences with a presumption that stressful life events are not uncommon in normal population. We administered to participants a dispositional form of the Posttraumatic Growth Inventory and the Personal View Survey-III. Item statistics for the measure were computed. We performed an explanatory factor analysis by using principal components with promax rotation and a confirmatory factor analysis by using structural equation modeling. Since the factor inter-correlations were higher than.40 we computed Schmid-Leiman transformation to obtain second-order general factor loadings. Inner consistencies and 15-day test-retest intracorrelations were calculated. RESULTS: Item discrimination indexes ranged from.28 to.72. Promax rotated principal components analysis pointed out a three-factor structure. It was found in model testing with structural equation modeling that three-factor structure was valid for the Turkish version of the PTGI. After computing second-order factor loadings, we detected that general factor accounted for 64 percentage of the total variance. Three subscales of the measure were the Changes in Self-Perception, Changes in Philosophy of Life, and Changes in Relationship. Internal consistency for the Changes in Self-Perception subscale was 0.88, for the Changes in Philosophy of Life subscale was 0.78, for the Changes in Relationship was 0.77, and for the overall items was 0.92. 15-day test-retest intra-correlation for the composite scores was 0.83 and intra-correlations for the subscale scores ranged from 0.70 to 0.85. CONCLUSION: Turkish version of the measure revealed a three-factor first-order structure. However, it seems that the concept of posttraumatic benefits measured by the PTGI has a tendency to represent a unidimensional psychological construct in Turkish sample. Since the three-factor structure was validated, three-subscales may also be used to make an extensive assessment instead of composite scores. The PTGI is a valid and reliable measure to be used in research purposes among Turkish individuals.Conference Object The Influence of Shift Work on Cognitive Functions and Oxidative Stress(Cambridge Univ Press, 2013) Ozdemir, P. G.; Selvi, Y.; Ozkol, H.; Aydin, A.; Tuluce, Y.; Boysan, M.; Besiroglu, L.Article An Investigation Into the Interactions Between Positive and Negative Aspects of Personality, Perfectionism, Coping, and Locus of Control: a Latent Profile Analysis(Kure Iletisim Grubu A.S., 2016) Boysan, M.; Kiral, E.Our main aim was to investigate whether a taxonomic or a continuum model best fit to the associations between positive and negative aspects of trait psychological constructs. Using a factor analytic approach, we found that positive aspects of personality, perfectionism, coping, and locus of control were discernible from negative aspects of these constructs. Adhering to latent profile analysis procedure, we found four latent homogenous subsets among which individuals differentiated in their levels of positive traits. These four latent homogenous groups were labeled as 'Extremely low positive traits with high agreeableness', 'Low positive traits', 'High positive traits with high agreeableness', and 'High positive traits'. Latent class analyses demonstrated that participants who reported greater scores on positive traits were classified into two groups based on agreeableness scores (latent class 3 vs latent class 4). However, these two high positive traits groups did not significantly differentiate in other positive or negative traits. At the other extreme, those who scored extremely low on positive traits were also distinguishable from 'Low positive traits' group (latent class 2) dependent on high agreeableness scores (latent class 1) and at higher risk in terms of lowest positive traits among these four latent homogenous groups. It was appeared that agreeableness operates counterproductively among low positive individuals. It is concluded that multidimensional trait constructs seem to have two aspects including positive and negative facets rather than operating along a continuum or being simple opposites.Article The Mediating Role of Pathological Worry in Associations Between Dissociative Experiences and Sleep Quality Among Health Staff(Kure Iletisim Grubu A.S., 2018) Yıldırım, A.; Boysan, M.; Yılmaz, O.There has been a growing interest in determining the antecedents of the significant associations between dissociative symptomatology and sleep. The aim of this study was to investigate the mediation effect of a tendency to elicit uncontrollable and excessive worry on the relationship between dissociation and poor sleep quality among non-shift working health staff. Eighty-five participants with a mean age of 31.19 ±7.14 (ranging from 18 to 54) involved within the study. The Penn State Worry Questionnaire (PSWQ), Dissociative Experiences Scale (DES), Pittsburgh Sleep Quality Index (PSQI) and a demographic questionnaire were administered. Mediation regression models were utilized to evaluate direct and indirect associations between worry, dissociation and sleep quality after controlling for age, gender, marital status, education, prior psychiatric disorders, familial loading and time spent watching TV series in a week. Regression models indicated that direct dose-response relationship between dissociative symptomatology and sleep quality was not statistically significant. However, indirect effects of dissociative symptoms though pathological worry were substantial. More specifically, we found that the DES total, absorption/ imaginative involvement and dissociative amnesia had significant indirect effects on poor sleep quality via excessive worry as measured by the PSWQ. We concluded that dissociative symptoms are indirectly associated with sleep through negative repetitive thoughts such as pathological worry. Therefore, new generation therapeutic approaches particularly mindfulness therapy should be considered in the first-line treatments of sleep disturbance.Article A Psychometric Investigation of the Turkish Version of the Children's Response Style Scale (Crss) Using Structural Mediational Analysis Approach(Kure Iletisim Grubu A.S., 2017) Sonkur, A.; Boysan, M.; Kadak, M.T.The study investigated the psychometric properties of the Turkish version of the Children's Response Style Scale (CRSS). Participants were 1358 students, aged 13-19, and about half of the sample consisted of girls (N= 640, 47.13%). Confrmatory factor analysis was conducted and the original two-factor structure of the CRSS was replicated among the Turkish sample. It was demonstrated that sub-scales of the Turkish version have good internal reliability, testretest reliability and convergent validity. Rumination, meta-cognitions, pathological worry, and thought suppression were found to be signifcant antecedents of depressive symptomatology in adolescents. Consistent with the conceptualization of the response styles theory, distraction was preventive from depressive symptoms. A structural equation model specifed based on an integration of the response styles theory (Nolen-Hoeksema, 1991) and the SelfRegulatory Executive Function (S-REF) model of emotional disorders (Wells, 2000; Wells &Matthews, 1996) detected that signifcant linkages between depression and metacognitions were mediated by thought suppression, rumination and worry among adolescents. Gender differences on measures of cognitive vulnerability factors were substantial that girls revealed a greater tendency to meta-cognitive vulnerability, thought suppression, rumination and pathological worry, while boys scored higher on distraction. Gender differences in depressive symptomatology fell short of signifcance when controlling for cognitive vulnerability factors. Age was not a signifcant antecedent of cognitive vulnerability factors and depressive symptoms. The results are discussed in light of theoretical and empirical evidence in the literature.Article The Psychometric Properties of the Clark-Beck Obsessive-Compulsive Inventory in a Turkish Population(2007) Beşiroǧlu, L.; Aǧargün, M.Y.; Boysan, M.; Güleç, M.; Eryonucu, B.Objective: We examined the psychometric properties of the Clark-Beck Obsessions and Compulsions Inventory eveloped to assess the frequency and severity of obsessive compulsive symptoms. Methods: The sample consisted of 52 OCD patients, 32 non-OCD patients with other anxiety disorders, 36 nonobsessional depressed patients, 75 healthy adults, and 278 undergraduate students. We investigated internal consistency, test-retest reliability, concurrent and discriminant validity of the instrument. Results: Cronbach's α coefficients for the CBOCI Obsessions, Compulsions and Total scale were found as 0.86, 0.83 and 0.91 in all samples respectively. The CBOCI obsessions (r=0.81, p<0.001), compulsions (r=0.85, p<0.001) and total score (r=0.85, p<0.001) showed a significant level of temporal stability. OCD patients scored significantly higher on CBOCI obsessions, compulsions and total scale than non-obsessional anxious, depressed patients, healthy control subjects. Obsession, compulsion and total scores of both OCD and nonclinical sample were significantly correlated with other scales assessing obsessive compulsive symptoms. Discussion: The Turkish version of the CBOCI has appropriate reliability and validity for assessing the frequency and severity of obsessive-compulsive symptoms.Conference Object Psychometric Properties of the Turkish Version of Sleep Hygiene Index in Clinical and Non-Clinical Samples(Cambridge Univ Press, 2015) Ozdemir, P. Guzel; Boysan, M.; Selvi, Y.; Yildirim, A.; Yilmaz, E.Article Relationships Between Somatosensory Amplification, Health Anxiety and Low Back Pain Among Pregnant Women(Yuzuncu Yil Universitesi Tip Fakultesi, 2019) Yıldırım, A.; Boysan, M.; Karaman, E.; Çetin, O.; Şahin, H.G.Introduction: A great proportion of pregnant women experience low back pain during pregnancy. The aim of this study was to uncover potential psychological mechanisms underlying pregnancy-related back pain. Method: Fifty two women with low back pain and forty seven women without low back pain were volunteered to participate in the study. A battery set containing the Health Anxiety Inventory (HAI), Hospital Anxiety and Depression Scale (HADS), Somatosensory Amplification Scale (SSAS), and Visual Analog Scale (VAS) was completed by all participants. Group comparisons were conducted using logistic regression analysis. Relationships of psychological symptoms with pain as measured by the VAS were assessed using regression analysis. Results: Regression models showed that somatosensory amplification satisfactorily explained the group difference between pregnant women with and without low back pain. A tendency to anomalous somatic sensation was associated with the individual differences on scores of the VAS. Conclusion: We concluded that pregnant women high in somatosensory amplification were at greater risk of development of low back pain during pregnancy. © 2019, Yuzuncu Yil Universitesi Tip Fakultesi.

Sixty-three healthy subjects (45 males and 18 females) were included in the present study. Of these participants, 41 were grouped in right-side sleeping position and 22 subjects were in left-side sleeping position. The subjects were interviewed in terms of dream recall frequency, vividness, bizarreness, nightmare frequency, and dream emotions suggested by Hartmann et al. PSQI was also administered to the subjects. The rate of nightmare sufferers was significantly higher in left-side sleepers (40.9%) than in right-side sleepers (14.6%). Relief-safety was more common among right-side sleepers than the others. Global PSQI score were significantly lower in right-side sleepers than left-side sleepers. These findings suggest that dreaming and sleep quality may be affected by body posture.Conference Object Socio-Demographic and Clinical Risk Factors on the Non-Recovery of the Major Depressive Disorder: a 52-Week Follow-Up Study(Cambridge Univ Press, 2012) Gulec, M.; Selvi, Y.; Boysan, M.; Aydin, A.; Besiroglu, L.; Agargun, M.
