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 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.Article Citation - WoS: 1Sürpriz Bir Eski/Yeni Tanıma Belleği Görevinde Yaşlı Yetişkinlerde Olumlu Kelimeler İçin Tepki Yanlılığı Değişimi: Bir Tesadüfi Kodlama Çalışması(Gunes Kitabevi Ltd Sti, 2017) Kaynak, Hande; Gökçay, DidemGiriş: 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 çekmektedirArticle Citation - WoS: 2Citation - Scopus: 1Relations Among Emotional Mood State Personality Dimensions and Social Desirability in Older Adults(Gunes Kitabevi Ltd Sti, 2018) Kaynak, HandeIntroduction: 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.
