Editorial The Bright and Dark Sides of Work Life" Tpd Work and Organizational Psychology Special Issue(Turkish Psychologists Assoc, 2019) Sumer, H. Canan; Goncu-Kose, Asli; Toker, Yonca; Ok, A. Basak; Gokalp, Aysu; Mete, Ipek; Demircioglu, Zeynep IsilArticle Citation - WoS: 6Investigation 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; PsikolojiIntroduction: 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.Article Citation - WoS: 3The 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; PsikolojiThe 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.Article Citation - WoS: 3The Mediator Effects of Positive and Negative Affectivity on the Relationship Between Optimism-Pessimism and Satisfaction With Life(Hacettepe Univ, 2013) Ugurlu, Ozanser; Uğurlu, Ozanser; PsikolojiThis study examined the mediation effects of positive and negative affectivity on the relationship between optimism/pessimism and satisfaction with life among university students. Participants were 95 female and 151 male undergraduate students (N = 246). Participants ranged in age from 18 to 26 with a mean of 21.09 (SD = 2.34). Participants completed Life Orientation Scale (LOT), Positive and Negative Affect Schedule (PANAS), and Life Satisfaction Scale. Results of correlational analyses demonstrated that the association between optimism and pessimism was -.40. Optimism was significantly associated with PA (r = .40), NA (r = -.26), and satisfaction with life (r = .36). Similarly, pessimism was significantly correlated with PA (r = -.26), NA (r = .39), and satisfaction with life (r = -.30). Finally, optimism had statistically significant direct and indirect links (by means of positive affectivity) with satisfaction with life, whereas pessimism only had statistically significant direct link with life satisfaction.Article Citation - WoS: 1Citation - Scopus: 3Bullying as a Group Process: Investigation of Participant Roles in Terms of Social Status and Gender(Turkish Psychologists Assoc, 2015) Topcu, Aysun Ergul; Donmez, AliThis 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 wereArticle Citation - WoS: 2The Mediator Role of Positive and Negative Affect in the Relationship Between Sleep Quality, Depressive Symptoms and Anxiety in Young Adults(Galenos Publ House, 2022) Yazihan, Naksidil; Tuna, Ezgi; Fidantek, HulyaObjective: It is known that individuals with poor sleep quality show significantly more depression and anxiety symptoms. It is important to investigate possible factors that may make individuals more vulnerable to develop depression and anxiety. For this purpose, the possible mediator roles of positive affect (PA) and negative affect (NA) in the relationship between sleep quality and depression- anxiety symptoms in young adults were tested by using multiple mediation analysis. Materials and Methods: The sample of the study consisted of 387 volunteer participants aged between 18 and 35 years (mean=22.83, standard deviation=3.20). Data consisting of Pittsburgh sleep quality index, positive and negative emotion scale, and brief symptom inventory were collected through an online computer-assisted protocol. Results: Significant positive correlations were found between low sleep quality scores and both depressive and anxiety symptoms. According to the two mediator variable models, low sleep quality influenced depressive symptoms indirectly through PA and NA, and anxiety through only NA. Alternative models of the results showed that depressive symptoms influenced sleep quality partially through PA and NA, while anxiety mediated this relationship only through PA. Conclusion: Alternative models tested to understand the direction of the relationship between depressive-anxiety symptoms and sleep quality. Although the results were significant, the explained variance was found to be less explanatory than the first and second models. The results of the study supported the idea that sleep quality, PA and NA should be targeted while developing prevention and intervention programs for depression and anxiety.Article Citation - WoS: 2Citation - Scopus: 3The Mediating Role of Cognitive Flexibility in the Relationship Between Metacognition and Psychological Health: a Study in a Non-Clinical Sample(Kare Publ, 2021) Aydin, Oyku; Kaynak, HandeObjective: Metacognition is a concept that refers to the awareness and control of individuals' cognitive processes. In this regard, metacognitive processes may promote cognitive flexibility. The present study investigates the impact of metacognitions on adults' psychological health and the mediating role of cognitive flexibility through bootstrap analysis. Method: The sample comprised of 212 university students. All volunteers had no history of psychiatric/neurological disorders and no use of medication affecting the central nervous system for the last six months. Participants were required to complete the Metacognitions Questionnaire-30, the General Health Questionnaire- 12, and the Cognitive Flexibility Inventory via an online survey. Results: According to the correlation analyses, cognitive flexibility was found to be negatively correlated with dysfunctional metacognition (r=-0.227, p<0.01) and poor psychological health (r=-0.397, p<0.01); dysfunctional metacognition was positively correlated with poor psychological health (r=0.399, p<0.01). We conducted mediation analyses via the bootstrapping method using a 95% confidence interval and 5000 bootstrap samples. The results showed that cognitive flexibility had a significant partial mediating role in the relationship between metacognition and psychological health [R-2=0.26, F(2, 209)=36.38, p<0.001]. Conclusion: The findings highlighted the importance of cognitive flexibility as an underlying mechanism through the relationship between metacognition and psychological health in a non-clinical sample. The results suggested the need to take "cognitive health" into account while attempting to promote "psychological health."Article Mediating Roles of Impulsivity and Risk-Taking in the Links of the Dark Triad With Flirting and Dating Via Social Media(Istanbul Univ, Fac Letters, dept Psychology, 2022) Demircioglu, Zeynep Isil; Goncu-Kose, AsliWith the acceleration of communication and access to information, individuals have begun to date via social networking sites. Although online dating has spread among university students recently, studies on this topic are very limited. The present study aimed to investigate the effects of the Dark Triad personality traits (i.e., Machiavellianism, psychopathy, and narcissism) on using Social Networking Sites (SNS) to find partners and face-to-face meeting/dating after flirting via the internet (i.e., face-to-face dating with a partner met via SNS). Furthermore, it was also aimed to identify the mediating roles of risk-taking and impulsivity in the relationships mentioned above. Data were collected from 358 University students (223 females and 135 males) who volunteered to complete the survey packages. The data was analyzed using Structural Equation Modeling (SEM). The age of the participants ranged between 18 and 49 (M = 22.67, SD = 2.83). The results revealed that narcissism was linked to using SNS to find partners, and impulsivity fully mediated the relationships of Machiavellianism with using SNS to find partners. In addition, the links of psychopathy with using SNS to find partners were partially mediated by impulsivity, with risk-taking fully mediating the effects of psychopathy and narcissism on face-to-face dating with a partner met via SNS. The present research revealed that impulsivity and risk-taking were the common attitudes underlying the links of psychopathy and narcissism with dating someone met via SNS. For individuals who score high on Machiavellianism, a low level of impulsivity is a protective factor; whereas a high level of impulsivity is a triggering factor that leads those with high psychopathy scores to search for partners via SNS. Contrary to expectations, narcissism was not directly associated with face-to-face dating a partner who was met via SNS. This finding may be related to the unidimensional measurement of narcissism, since grandiose narcissism is more likely to be positively associated with this risky and confident behavior, whereas vulnerable narcissism is less likely to have such an association.Article Hangi Lider, Kurumda Kalmayı Nasıl Sağlıyor? Çok Boyutlu İş Motivasyonunun Aracı Rolü(2019) Metin, U. Baran; Göncü-köse, AslıYöneticilerin 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.Article Citation - WoS: 1Citation - Scopus: 1Direct and Indirect Relationships Between Cognitive Flexibility and Covid-19 Related Psychological Distress: the Mediating Role of Maladaptive Cognitive Emotion Regulation Strategies(Klinik Psikiyatri dergisi, 2022) Sayinta, Senanur; Kocak, Hatice Nur; Kaynak, HandeObjective: The effects of the COVID-19 pandemic are remarkable on individuals' mental health. During the COVID-19 pandemic, there is an increase in mental health problems and psychological distress in uninfected healthy people. The present study aimed to examine the mediator role of maladaptive cognitive emotion regula-tion strategies in the relationship between cognitive fle-xibility and COVID-19 related psychological distress experienced during the current pandemic. Method: The sample consisted of 351 young adults (86% female and 14% male) who were not infected with COVID-19 aged between 18 to 25 years old. Participants completed the self-report questionnaires, including the Cognitive Flexibility Inventory, Cognitive Emotion Regulation Questionnaire, and COVID-19 Related Psychological Distress Scale. Mediation analysis estimated total, indi-rect, and direct effects between cognitive flexibility and COVID-19 related psychological distress. Results: The correlation analyses showed that cognitive flexibility -control dimension was negatively associated with both COVID-19 related psychological distress and maladaptive cognitive emotion regulation strategies. Also, maladap-tive cognitive emotion regulation strategies and COVID-19 related psychological distress was found to be posi-tively correlated. In the study sample, the results of the bootstrap mediation indicated that maladaptive cogni-tive emotion regulation strategies, including self-blame, acceptance, rumination, catastrophizing, and blaming others, fully mediated the relationship between cogni-tive flexibility -control and COVID-19 related psycholog-ical distress. Discussion: Our findings would help psy-chological interventions designed for COVID-19 unin-fected healthy people who have lower-level cognitive flexibility -control dimension by highlighting the promi-nence that the fewer people use maladaptive cognitive emotion regulation strategies, the less they feel COVID-19 related psychological distress.
