The purpose of this study was to adapt the self-hate scale (SHS; Turnell et al., 2018) into Turkish in a community sample, and test the validity and reliability of the measure. The study was conducted with 234 individuals. After the translation procedures, the language equivalence was examined, and a significant positive relationship was found between the Turkish and English forms. Findings of the reliability and validity analyses indicated that the Turkish SHS confirmed seven items in one factor with good factor loadings. Good fit values and reliability coefficients were determined with the SHS-Turkish Form. Self-hate was positively correlated with self-disgust, behavior-based self-disgust, physical appearance-based self-disgust, depression, anxiety, and interpersonal sensitivity. Self-hate also indicated a negative correlation with self-compassion. Simple linear regression analyses results showed that self-hate predicted depression, anxiety, and interpersonal sensitivity scores. T...

Grup danismanligi bireysel danismanliktan daha kolay uygulanabilir ve sonuclarinin gozlenebilir olmasi dolayisiyla bircok problemin cozumu uzerinde etkili bir yontemdir. Arastirmanin amaci, bilissel ve bilissel-davranisci grup danismanligi metotlari kullanilarak 9. sinif ogrencilerinin sosyal kaygi duzeylerini azaltmaktir. Arastirma grubu yuksek kaygi yasayan ogrenciler arasindan gonullu olarak secilmis olan 10 ogrenciden olusmaktadir. Bu ogrencilerle 10 oturumluk bir psiko-egitim programi calismasi yapilmistir. Arastirmada olcek olarak Capa Ergenler icin Sosyal Kaygi Olcegi (CESFO) kullanilmistir. Veri analizinde bagimsiz gruplar icin Wilcoxon testi kullanilmistir. Uygulanan grup calismasinin ergenlerin sosyal fobisinin azalmasi uzerinde etkili oldugu gorulmustur. Calisma bulgularindan hareketle ergenlerin sosyal fobisinin azaltilmasinda iletisim becerileri grup rehberligi programinin yararli oldugu sonucuna varilmistir.

Introduction: In this study, it is aimed to assess the validity and reliability of Reinforcement Sensitivity Questionnaire (RSQ) which was developed on the basis of revised Reinforcement Sensitivity Theory (rRST) in Turkish community sample. Methods: The sample of study was consisted of 528 participants, 314 (59.5%) female and 214 (40.5%) male, in the range of 18-69 years. Data was collected by using online data collection tools via snowball method. Within the scope of the reliability study, test-retest application, split-half method and internal consistency analysis; within the scope of the validity study, explanatory factor analysis and confirmatory factor analysis were performed. For criterion-related validity Behavioral Inhibition System / Behavioral Activation System Scale (BIS/BAS), Eysenck Personality Questionnaire Revised-Abbreviated Form (EPQR-A) and State-Trait Anxiety Inventory (STAI-II) were applied. Results: At the result of reliability analysis, the Cronbach Alpha inte...

Objective: The aim of this study is to investigate the change in psychological symptoms that occur after the COVID-19 epidemic in terms of psychological resilience and posttraumatic growth. In addition, it was aimed to determine the mediating role of PS in the relationship between before COVID-19 psychological symptoms of individuals and their subsequent psychological symptoms. Method: It was applied psychological symptoms, psychological resilience, and posttraumatic growth scales to the participants, who consisted of 1245 people, 1212 female (81.3%), and 233 (18.7%) male, between the ages of 18-74 as online. Results: When the differences between the groups formed according to the change in symptom scores before and after COVID-19 were examined, it was found that the resilience score was significantly higher in favor of the group with no change, and the posttraumatic growth score in favor of the group with the positive change that compared to the other change groups. In the relation...

Objective: This study aims to test psychometric properties of The Personality Belief Questionnaire-Short Turkish Form (PBQ-STF) in the community sample and to determine the validity and reliability of the Borderline Personality Disorder subscale, which was not included in the previous Turkish adaptation studies. Method: PBQ-STF was administered to a sample of 650 participants (in the age range of 18-66 years, 362 women (55.7%) and 288 men (44.3%)). Test-retest reliability was applied on a group of 30 person from sample with interval four weeks. For testing convergent validity, Beck Depression Inventory (n=108), State-Trait Anxiety Inventory (n=100) and Dysfunctional Attitude Scale (n=108) were also employed. Results: Cronbachs alpha values varied between .70-.84. Test-retest reliabilities were .77-.90. PBQ-SFs all subscales were correlated each other positively. In the exploratory factor analysis (EFA), PBQ-STF subscales revealed two factors explained 70,89% of the total variance. In the confirmatory factor analysis (CFA), it was seen adaptive statistical values of scale were at acceptable/agreeable level. Conclusion: According to the results obtained from the analyzes made, it was determined that PBQ-STF has strong psychometric evidence and is a reliable and valid scale that can be used in evaluating personality beliefs.
