Bullying as a Group Process: Investigation of Participant Roles in Terms of Social Status and Gender
(Turkish Psychologists Assoc, 2015) Topcu, Aysun Ergul; Donmez, Ali; 173556
This study mainly aims to test the participant roles approach on Turkish sample suggesting that bullying is a group process. In this regard, students' ways of involving in bullying and the extent to which children are aware of their participant roles and whether these participant roles differentiate in terms of gender and social status was investigated. A total of 774 students (384 females and 390 males), from 6(th), 7(th) and 8(th) grades of 11 different primary schools in Ankara participated in the study. The results showed that 74% of all children involved in one of the participant roles as bully (11.5%), assistant-reinforcer (10.9%), defender (21.1%), outsider (20.9%) and victim (9.7%). The examinations of the relations between self-reported and peer-reported scores of participant roles revealed that children were aware of their roles in the bullying situations, however, they significantly underestimated their roles in bully and assistant-reinforcer scales while overestimated their roles in the defender and outsider scales. Boys are more actively involved in bullying process than girls; boys participated most frequently in the roles of bully, assistant-reinforcer and victim while girls participated most frequently in the defender and outsider roles. In terms of the findings related to social status, victims were the least accepted and most rejected group among their peers although they did not differentiate from bullies and assistant-reinforcer in this sense. Besides, the victims were

(Turkiye Sinir ve Ruh Sagligi dernegi, 2015) Altunoz, Umut; Baştuğ, Gülbahar; Ozel Kizil, Erguvan Tugba; Kirici, Sevinc; Bastug, Gulbahar; Bicer Kanat, Bilgen; Sakarya, Aysegul; Turan, Engin; 48292; Psikoloji
Objective: The aim of this study was to investigate the dimensions of agitation in dementia patients using the Turkish version of the Cohen-Mansfield Agitation Inventory (CMAI-T). Materials and Method: The study included 100 patients diagnosed as dementia, according to the DSM-IV-TR. The CMAI-T was administered to the patients' caregivers via face-to-face interviews. The Standardized Mini Mental State Examination (SMMSE) was used to assess cognitive functions. The severity of depression and the functional state of the patients were assessed using the Cornell Scale for Depression in Dementia (CSDD) and the Functional Activities Questionnaire (FAQ). Principal component analysis and varimax rotation were used to determine the factor structure of the CMAI-T. Results: Factor analysis of the CMAI-T indicated a 3-factor structure: physically aggressive agitation, verbal agitation, and physically non-aggressive agitation. In 92% of the patients there >= 1 was agitation behavior during the previous 2 weeks. The CMAI-T total and factor scores were negatively correlated with the SMMSE scores, and positively correlated with the CSDD and the FAQ scores. Conclusions: The CMAI-T yielded 3 factors (physically aggressive agitation, verbal agitation, and physically non-aggressive agitation), which indicated the scale had construct validity Agitation behaviors were associated with cognitive dysfunction, symptoms of depression and general level of functioning. Additional research is necessary to identify the predictors of these dimensions in different dementia samples, and to determine the efficacy of therapeutic interventions.
Hangi Lider, Kurumda Kalmayı Nasıl Sağlıyor? Çok Boyutlu İş Motivasyonunun Aracı Rolü
(2019) Metin, U. Baran; Göncü-köse, Aslı; 166202
Yöneticilerin liderlik tipleri çalışanların iş motivasyonlarını en fazla etkileyen faktörler arasında yer almaktadır ancak, Türkiye’de hem bu etkileri hem de liderlik stillerinin çalışan motivasyonları aracılığı ile işle ilgili diğer sonuçdeğişkenleri üzerindeki etkilerini inceleyen araştırmalar az sayıdadır. Bu çalışmanın amacı, yöneticilerin babacan vedönüşümcü liderlik stilleri ile çalışanların çok boyutlu iş motivasyonları arasındaki ilişkileri geçerliği ve güvenirliğitest edilmiş bir ölçek kullanarak Türkiye örnekleminde incelemek (Çalışma 1); ayrıca, liderlik tipleri ile işten ayrılmaniyetleri arasındaki ilişkilerde çok boyutlu iş motivasyonunun kısmi aracı rolünü test etmektir (Çalışma 2). Bu amaçla,Çalışma 1’de 456 çalışandan veri toplanmış ve Gagné ve arkadaşları (2014) tarafından Öz Belirleme Kuramı (Decive Ryan, 1985) temel alınarak geliştirilen Çok Boyutlu İş Motivasyonu Ölçeği’nin (ÇBİMÖ) Türkçeye adaptasyonçalışması gerçekleştirilmiştir. Çalışma 2’de 388 çalışandan veri toplanmış ve önerilen model yapısal eşitlik modellemesi yöntemiyle test edilmiştir. Çalışma 1’in bulguları, ÇBİMÖ’nün diğer ülkelerde yapılan çalışmaların gösterdiği faktöryapılarına uyumlu bir yapı gösterdiğini ve yordayıcı geçerliği olduğunu ortaya koymuştur. Çalışma 2’nin bulguları,genel olarak iki liderlik stilinin de motivasyon tipleriyle önerilen ilişkileri gösterdiğini ancak, iş motivasyonlarınınyalnızca dönüşümcü liderlik ile işten ayrılma niyetleri arasındaki ilişkide kısmi aracılık ettiğini göstermiştir. Bulgular,kuramsal ve uygulamaya yönelik çıkarımlar ile gelecekteki çalışmalara yönelik önerilerle birlikte tartışılmıştır.

Hangi Lider, Kurumda Kalmayı Nasıl Sağlıyor? Çok Boyutlu İş Motivasyonunun Aracı Rolü
(Turkish Psychologists Assoc, 2019) Goncu-Kose, Asli; Metin, U. Baran; 166202
Supervisors' leadership styles are among the most important variables that influence employees' work motivation. However, in Turkey, only a limited number of studies examined the effects of leadership styles on employee motivations and on distal work-related outcomes via their influences on these motivations. The present study aimed to examine the links of paternalistic and transformational leadership with employees' work motivations by using a valid and reliable work motivation measure and to test the mediating roles of motivations in the relationships between leadership styles and employees' turnover intentions. In Study 1, data were collected from 456 employees and the Multidimensional Work Motivation Scale (MWMS; Gagne et al., 2014), which was developed within the framework of Self-Determination Theory (Deci & Ryan, 1985), was adapted to Turkish. In Study 2, data were collected from 388 employees and the proposed model was tested using structural equation modeling. Study 1 revealed that the factor structure and the predictive validity results of the adapted MWMS were consistent with those of its versions in other languages. Study 2 showed that both leadership styles were associated with motivation dimensions in the proposed directions; however, motivations partially mediated only the link between transformational leadership and turnover intentions.

Investigation of the Psychometric Properties of the Turkish Form of Subjective Memory Complaints Questionnaire
(Gunes Kitabevi Ltd Sti, 2013) Ozel Kizil, Erguvan Tugba; Baştuğ, Gülbahar; Duman, Berker; Altintas, Ozge; Kirici, Sevinc; Bastug, Gulbahar; Baran, Zeynel; Altunoz, Umut; 48292; Psikoloji
Introduction: Amnestic type of mild cognitive impairment (MCI) is characterized by the presence of subjective memory complaints and impairment of memory tests. This study aims to investigate the validity and reliability of the Turkish Version of the Subjective Memory Complaints Questionnaire (SMCQ). Materials and Method: The study sample consisted of 45 MCI patients and 44 healthy elderly controls. The SMCQ is a 14-item, "yes-no" questionnaire which evaluates the severity of subjective memory complaints. The discriminant validity of SMCQ was evaluated by comparing the scores of the two groups. For concurrent validity, the correlations between SMCQ and two widely-used cognitive screening tests (MMSE and ADAS-Cog) were calculated. ROC analysis was performed to test the diagnostic validity. For reliability analysis, internal consistency was calculated. Results: SMCQ scores of the patients were higher than the controls. SMCQ scores of the subjects were positively correlated with ADAS-Cog and negatively correlated with MMSE scores. Cronbach's value was 0.83. ROC analysis yielded a sensitivity of 80% and a specificity of 66% (cut-off=4.5). Area under the curve was 0.843. Conclusion: SMCQ is a valid and reliable instrument that can be used for the assessment of SMC in elderly patients. However, community based studies should be carried out for suggesting SMCQ as a screening tool.

Misinterpretations of Intrusions, Obsessive Beliefs and Thought Control Strategies in Patients With Obsessive-Compulsive Disorder
(Cumhuriyet Univ Tip Fak Psikiyatri Anabilim Dali, 2013) Yorulmaz, Orcun; Baştuğ, Gülbahar; Bastug, Gulbahar; Tuzer, Verda; Goka, Erol; 48292; Psikoloji
Objective: Misinterpretations of intrusive experiences are suggested to play critical role in the development and maintenance of obsessive-compulsive disorder (OCD). Some faulty belief domains are also assumed to contribute to the immediate misappraisal of intrusions and thus, patients with OCD try to control their thoughts with various thought control strategies. This study aims to examine these cognitive concepts among Turkish patients with OCD and comparatively review the psychometric characteristics of three instruments in clinical samples. Methods: The sample of the study was constituted of patients with OCD and any other anxiety disorders and undergraduate university students as control group. An instrument set on immediate misinterpretations, beliefs, control strategies, responsibility attitudes, fusions of thoughts and actions, thought suppression, OCD symptoms, self-esteem and personality characteristics was administered to the sample. Results: Having acceptable reliability values, instrument tools of immediate interpretations, beliefs and thought control methods were found to be higher in OCD patients. These three factors were found to be significantly associated with other relevant cognitive correlates, while they were not related to some other factors such as psychoticism. Conclusion: These findings show that misinterpretations of intrusions, beliefs and control methods are also valid concepts in Turkish clinical samples that live in a different cultural context, and the self-report instruments of these cognitive factors were shown to display satisfactory psychometric properties.

Neuroticism and introversion mediates the relationship between probable ADHD and symptoms of Internet gaming disorder: results of an online survey
(Aves, 2019) Evren, Bilge; Evren, Cuneyt; Dalbudak, Ercan; Topcu, Merve; Kutlu, Nilay; 256656
OBJECTIVES: The aim of the present study was to evaluate relationship of probable attention deficit hyperactivity disorder (ADHD) with severity of the Internet gaming disorder (IGD), neuroticism and extraversion. METHODS: The study was conducted with online survey among 457 volunteered university students in Ankara and people who play games on the Internet and who are in the e-mail database of a company located in Istanbul that organizes e-sports tournaments. Participants were evaluated by applying the Adult ADHD Self-Report Scale (ASRS-v1.1), the 9-item Internet Gaming Disorder Scale (IGDS) and the Eysenck Personality Questionnaire Revised-Abbreviated Form (EPQR-A). RESULTS: Age was lower among those with the probable ADHD (n = 102, 22.3%) and those without (n = 355, 77.7%). Gender, educational status, and type of the participants did not differ between the groups. Severity of IGD symptoms and neuroticism were higher among those with the probable ADHD, whereas extraversion was lower. In logistic regression analysis, severity of IGD symptoms predicted the probable ADHD in the first Step, whereas when extraversion and neuroticism were included in the analysis as independent variables, low extraversion (introversion) and high neuroticism predicted the probable ADHD and severity of IGD symptoms was no longer a predictor. CONCLUSION: These findings suggest that the severity of IGD symptoms is related with the probable ADHD and low extraversion (introversion) and high neuroticism may have mediator effect on this relationship.

Psychometric validation of the Turkish gaming disorder test: A measure that evaluates disordered gaming according to the World Health Organization framework.
(Aves, 2020) Evren, Cuneyt; Pontes, Halley M.; Dalbudak, Ercan; Evren, Bilge; Topcu, Merve; Kutlu, Nilay; 256656
Background: Previous research on gaming disorder (GD) used psychometric tools, which evaluates according to the American Psychiatric Association (APA) diagnostic framework. The Gaming Disorder Test (GDT), a standardized measure to assess symptoms and prevalence of GD according to the World Health Organization (WHO) diagnostic framework. The main aim of the current study was to adapt the GDT to Turkish. Methods: In the present study participants were assessed with the GDT, the Internet Gaming Disorder Scale-Short-Form (IGDS9-SF), and the CAGE-Problematic Internet Use Questionnaire (CAGE-PIUQ). The factor structure of the scale was tested with Con.rmatory Factor Analysis (CFA), and reliability and validity analyses were conducted. Results: A sample of 932 Turkish gamers (58.3% male, mean age 23.64 years, SD=5.42) was recruited online. Confirmatory factor analyses demonstrated that the unidimensional factor structure of the GDT was satisfactory. The scale was also reliable (i.e., internally consistent with a Cronbach's alpha of 0.879) and showed adequate convergent and criterion-related validity, as indicated by statistically significant positive correlations between average time daily spent playing games (ATDSPG) during last year, IGDS9-SF and CAGE-PIUQ scores. By applying the International Classification of Diseases 11th edition (ICD-11) threshold for diagnosing GD (e.g., meeting all four criteria by answering them either with 'often' [4] or 'very often' [5]), it was found that the prevalence of GD is 1.9% (n = 18). Conclusions: Online gaming preference, ATDSPG and probable ADHD predicted the severity of disordered gaming. These findings support the Turkish version of the GDT as a valid and reliable tool for determining the extent of GD related problems among young adults and for the purposes of early GD diagnosis in clinical settings and similar research.

Relations Among Emotional Mood State Personality Dimensions and Social Desirability in Older Adults
(Gunes Kitabevi Ltd Sti, 2018) Kaynak, Hande; 101097
Introduction: Previous studies have shown that older adults report higher levels of positive affect (PA). Studies in the context of the five-factor model of personality have also noted the age-related changes in personality. However, the possible influence of personality on emotional state needs further investigation in older adulthood. This study examines relations among personality traits, social desirability, and positive/negative affectivity in conjunction with aging. Materials and Method: A total of 123 volunteers (62 young and 61 older adults) was participated in the study. A cross-design was used with consecutive sampling. All participants had higher education. Participants completed the Positive and Negative Affect Schedule as a measure of emotional state. Thereafter, they rated the degree to which each item described themselves on the Five-Factor Personality Inventory, which measures personality dimensions and social desirability. Results: Independent t-tests were conducted to compare young and older adults in terms of affectivity and personality. Findings revealed that older adults reported less negative affect (NA) compared with young adults. Older adults scored higher on agreeableness, conscientiousness, and social desirability, whereas young adults scored higher on extraversion and neuroticism. Based on correlational results, neuroticism was negatively correlated with extraversion, social desirability, and PA in older adults. Analyses of variance showed that conscientiousness, neuroticism, and social desirability impacted positive/negative affectivity. Conclusion: The results indicated that neuroticism proved to be the most important factor on emotional well-being. Older adults low on neuroticism experienced less NA. Furthermore, conscientiousness and social desirability had strong effects on PA indicating that the age-related differences found in affectivity might not only be attributable to age-related changes in personality, but also partly attributable to age-related increases in social desirability.

Response bias shift for positive words in older adults in a surprise recognition memory task: an incidental encoding study
(Gunes Kitabevi Ltd Sti, 2017) Kaynak, Hande; Gökçay, Didem; 101097
Giriş: Yaşlı bireylerin özellikle olumlu kelimeleri bellekte daha iyi tuttukları bilinmesine rağmen, duygunun iki boyutunun (olumluluk ve heyecan düzeyleri) tesadüfi kodlama yapılan tanıma belleği performansı üzerindeki etkisi hâlâ netlik kazanmamıştır. Araştırmanın amacı, tesadüfi kodlanan ve olumluluk (olumlu, olumsuz ve nötr) ve heyecan düzeyleri (yüksek ve düşük) değişimlenen kelimelerin tanıma belleği puanları (bellek doğruluğu ve tepki yanlılığı) üzerindeki etkisini, sürpriz bir eski/yeni tanıma belleği göreviyle incelemektir. Gereç ve Yöntem: Çalışmaya, 60 genç ve 53 yaşlı olmak üzere 113 gönüllü katılmıştır. İlk olarak, duygusal kelimeler bilgisayarda tek tek sunulmuş, tesadüfi kodlama yapması istenen katılımcılardan kelimelerin kaç sesli harften oluştuğunu belirtmesi istenmiştir. 30 dakikadan sonra, test aşamasına geçilmiş, çalışma aşamasına atıfta bulunarak daha önce gördükleri kelimeleri tanımaları yönünde yönerge sunulmuş, sürpriz bir eski/yeni tanıma göreviyle bellek performansı kaydedilmiştir. Bulgular: 2×3×2 son faktörde tekrar ölçümlü deney deseni kullanılmıştır. Bağımlı değişken, tanıma belleği puanları olup, Sinyal Belirleme Kuramı temel alınarak bellek doğruluğu ve tepki yanlılığı hesaplanmıştır. Varyans analizlerine göre, yaşlıların kelimelerin olumluluk düzeyi açısından bellek doğruluğu puanları değişmemekle birlikte, özellikle olumlu kelimelere karşı istatistiksel olarak anlamlı bir tepki yanlılığı gösterdikleri bulunmuştur. Sonuç: Yaşlılar olumsuz kelimelere nazaran olumlu kelimelere daha çok önem vermektedir. Kelimelerin çaba harcamadan, tesadüfi kodlandığı koşulda, yaşla birlikte ortaya çıkan bu farklılık, yaşlıların iyi olma hallerini korumak adına duygularını düzenlediklerini öne sürmektedir. Çalışmamız bellek performansı ölçümlerinde, yaşla ilişkili etkenlerin belirlenmesinin önemine dikkat çekmektedir

Sleep spindle-related electroencephalograph activity of young adults and its relation to cognitive functionsc
(Ege Univ, 2019) Yazihan, Naksidil Torun; Yetkin, Sinan; 276238
Objective: Sleep spindles are phasic bursts of thalamocortical activity, typically defined as 11-16 Hz (in sigma frequency band) with a duration of 0.5 and 2 seconds. Spindles are most prominent during N2 sleep and are a defining feature of this stage. The aim of the present study was to investigate the association between spindle characteristics and cognitive functions of young adults. Methods:The study sample consisted of 17 healthy male subjects aged between 19 and 28 years.The participants had no medical or psychological conditions and were not taking any medications that might affect their sleep pattern and neuropsychological measurements. Polysomnography recordings were conducted from 22:30 to 07:00 hour for two subsequent nights. The first night was for adaptation to the laboratory conditions and to rule out sleep apnea syndrome and periodic leg movements. The second night was used to analyze macro and micro parameters of sleep. A neuropsychological test battery comprising the Serial Digit Learning Test, Raven Standard Progressive Matrices, Verbal Fluency Test,Trail Making A-B, and the Auditory Verbal Learning Test were administered before the second-night sleep session. Sleep spindles in all non-rapid eye movement stage 2 sleep were scored visually from C3-A2 electroencephalogram derivation after polysomnographic analysis was completed. Each 30-sec epoch was analyzed with a high-pass band filtered at 0.3 Hz, and a low-pass band filtered at 35 Hz. Spindle characteristics such as duration, amplitude, mean and peak frequencies were analyzed using the fast Fourier transform algorithm. The association between the characteristics of sleep spindles and the neuropsychological test scores were analyzed using Spearman correlations. Results: Significant positive correlations were found between spindle density and both verbal auditory learning performance and verbal fluency, cognitive flexibility, and semantic organization performances. The serial digit learning test was correlated positively with mean duration, mean frequency, and peak frequency of sleep spindles. Finally, the mean duration, and mean frequency of spindles were positively correlated with verbal fluency, cognitive flexibility, and semantic organization. Conclusion: The associations between spindle features and memory, verbal fluency, and verbal learning abilities were consistent with previous research findings suggesting that sleep spindles might be related to cognitive abilities and the potential to learn. In other words, it might be an indicator of the current level of aptitude for learning.

The relationship among leadership style, sex of leader, and sex of evaluator in the evaluation of leadership behavior
(Turkish Psychologists Assoc, 2011) Ugurlu, Ozanser; Uğurlu, Ozanser; Hovardaoglu, Selim; Psikoloji
The purpose of the article was to investigate the relationships among leadership style, sex of leader, and sex of evaluator in the evaluation of leadership behavior in a student sample from Turkey. In order to reach the goal, leadership style and sex of leader were manipulated to prepare four vignettes as autocratic female leader, democrat female leader, autocratic male leader, and democrat male leader. The participants were 386 university students from Middle East Technical University (199 males and 187 females; M=21.74; SD=1.56). After reading one of the vignettes, the participants evaluated the leader by filling out the Evaluation of Leadership Behavior Scale. A 2 (sex of leader: female - male) X 2 (leadership style: autocratic - democrat) X 2 (sex of evaluator: female - male) ANOVA was performed on the evaluation of leadership behavior. Results demonstrated that there was a significant main effect of leadership style. As expected, participants evaluated democratic leader more positively than autocratic leader. In addition, there was a significant two-way interaction between leadership style and sex of evaluator, suggesting that male participants evaluated democratic leader less positively than female participants and that male participants evaluated autocratic leader more positively than female participants. Finally, there was a significant three-way interaction. Both male and female participants evaluated autocratic female leader more negatively than democratic female leader. Further, as compared to male participants, female participants evaluated both democratic male leader and democratic female leader more positively.
