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.Conference Object Relationship of Difficulties in Emotion Regulation With Attention Deficit/Hyperactivity Disorder Among Young Adults(Cambridge Univ Press, 2019) Evren, C.; Evren, B.; Dalbudak, E.; Topcu, M.; Kutlu, N.Article Citation - WoS: 8Citation - Scopus: 8Dimensions of Agitation Based on the Cohen-Mansfield Agitation Inventory in Patients With Dementia(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; Kanat Biçer, Bilgen; PsikolojiObjective: 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.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: 11Citation - Scopus: 12Relationship of Internet Gaming Disorder Severity With Symptoms of Anxiety, Depression, Alexithymia, and Aggression Among University Students(Kare Publ, 2019) Evren, Cuneyt; Evren, Bilge; Dalbudak, Ercan; Topcu, Merve; Kutlu, NilayObjective: The aim of the present study was to evaluate the relationship of Internet gaming disorder severity with alexithymia and aggression among university students, while controlling for effects of anxiety and depressive symptoms. Method: The study was conducted with an online survey among 987 volunteer university students in Ankara. Participants were evaluated by administering the Toronto Alexithymia Scale (TAS-20), the Buss-Perry Aggression Questionnaire (BPAQ), the Internet Gaming Disorder Scale-Short-Form (IGDS9-SF), and the depression and anxiety subscales of the 90-Item Symptom Checklist-Revised (SCL-90-R). Results: Scores for the different scales mildly correlated with one other. In hierarchical linear regression analysis, both alexithymia (particularly the dimensions "difficulty identifying feelings" [DIF] and "externally-oriented thinking" [EOT]) and aggression (physical aggression) predicted the severity of Internet gaming disorder symptoms, together with severity of depressive symptoms. Conclusion: These findings suggest that among university students, the severity of alexithymia, particularly in its dimensions DDF and EOT, is related with the severity of Internet gaming disorder, together with aggression, particularly physical aggression, and depression.
