The moderated mediation role of metacognitions and ways of coping in the relationship between psychological resilience and anxiety

Bu araştırmanın amaçlarından biri kaygı, psikolojik dayanıklılık, başa çıkma yolları ve patolojik üstbilişler arasındaki ilişkileri incelemektir. Araştırmanın ikinci amacı ise psikolojik dayanıklılık ve kaygı arasındaki ilişkide patolojik üstbilişlerin ve başa çıkma yollarının durumsal aracılık rollerini değerlendirmektir. Çalışma kapsamında 18-65 yaşları arasında 292’si kadın (%65.6), 153’ü erkek (%34.4) toplam 445 kişiden veri toplanmıştır. Katılımcılara, Demografik Bilgi Formu, Durumluk-Sürekli Kaygı Envanteri, Yetişkinler için Psikolojik Dayanıklılık Ölçeği, Başa Çıkma Yolları Envanteri ve ÜstBiliş Ölçeği-30 uygulanmıştır. Kaygı, psikolojik dayanıklılık, başa çıkma yolları ve patolojik üstbilişler arasındaki ilişkileri değerlendirmek için korelasyon analizi, değişkenlerin kaygıyı yordama güçlerini görmek için hiyerarşik regresyon analizi ve patolojik üstbilişler ile başa çıkma yollarının durumsal aracılık rollerini değerlendirmek için durumsal aracılık analizi yapılmıştır. Korelasyon analizine göre patolojik üstbilişler ve başa çıkma yolları arasında istatistiksel açıdan anlamlı bir ilişki bulunmamıştır. Diğer ilişkilere ait korelasyon katsayılarının .10 ile .61 arasında değiştiği görülmektedir. Regresyon analizine göre psikolojik dayanıklılık, patolojik üstbilişler ve başa çıkma yolları değişkenleri kaygıya ait varyansın %58’ini açıklamaktadır. Son olarak patolojik üstbilişlerin, psikolojik dayanıklılık ve kaygı arasındaki ilişkiye aracılık ettiği ve bu aracılık ilişkisinde duygusal başa çıkmanın düzenleyici rolünün olduğu görülmektedir. Mevcut çalışmanın sonuçlarına bir bütün olarak bakıldığında psikolojik dayanıklılığın, üstbilişsel süreçlerin ve başa çıkma yollarının kaygının önemli açıklayıcıları oldukları ve özellikle terapötik müdahalelerde söz konusu değişkenlerin çalışılmasının önemli olabileceği söylenebilir.One of the purposes of this study was to examine the relationships between anxiety, psychological resilience, ways of coping, and pathological metacognition. The second purpose was to evaluate the moderated mediating role of pathological metacognition and ways of coping in the relationship between psychological resilience and anxiety. Within the scope of the study, data was collected from 445 individuals of whom 292 (65.6%) were females and 153 (34.4%) were males. The participants completed Demographic Information Form, the State-Trait Anxiety Inventory, the Resilience Scale for Adults, the Ways of Coping Inventory and the Metacognitions Questionnaire-30. Correlation analyses were conducted to evaluate the relationships between anxiety, psychological resilience, ways of coping, and pathological metacognitions; hierarchical regression analyses were conducted to see the predictive power of the variables on anxiety and moderated mediation analyses were conducted to evaluate the moderated mediator roles of pathological metacognitions and ways of coping. According to the correlation analyses, there was no statistically significant relationship between pathological metacognitions and ways of coping. Correlation coefficients related to other relationships ranged between .10 and .61. According to the regression results psychological resilience, pathological metacognitions, and ways of coping explained 58% of the variance of anxiety. Finally, the findings indicated that pathological metacognitions had a mediating role in the relationship between psychological resilience and anxiety, and that emotional coping moderated this mediation. Taking all the findings of the current study together, it can be argued that psychological resilience, pathological metacognitions, and ways of coping are important factors in explaining anxiety and that working on these variables especially in a therapeutical context can be beneficial

Deaths from Motorcycle Accidents: An Autopsy Study from Turkey

Motorcyclists and pillion passengers in road traffic accidents have an increased risk of morbidity and mortality because of lack of adequate safety systems. The purpose of this study was to analyze the injuries sustained by motorcycle riders and pillion passengers in fatal motorcycle accidents. A total of 56 cases autopsied in the Istanbul Morgue Department of the Council of Forensic Medicine were included in this study. The majority of the cases were young males. Fifty (89.3%) cases were riders and six (10.7%) were pillion passengers. The vast majority (78.6%) of the cases died at the scene or on the same day in hospital. Most of the cases had multiple traumas, and the most common trauma was head trauma (n = 45). The most common injury was intracranial hemorrhage (n = 40). Fifteen (26.8%) cases tested positive for drug and/or alcohol intake. These autopsy findings can be helpful for medicolegal examinations to diagnose possible injuries and also for the automotive industry to improve better protective safety devices for motorcycle riders

Üniversite Öğrencilerinde Sosyal Kaygı Belirtilerini Azaltmaya Yönelik Birleştirilmiş Bilişsel Yanlılık Değişimleme Çalışması: Deneysel Bir Araştırma

The study was conducted with the participation of 84 university students who display symptoms of social anxiety. The participants were randomly assigned into two groups; cognitive bias manipulation group (D) and placebo-control group (DP). The participants in group D took part in an attentional and interpretational bias manipulation study that was conducted through a computer in eight sessions, being twice a week. On the other hand, the participants in group DP attended a similar study with the one that group D attended, where no manipulation is carried out. The levels of social anxiety, anxiety, depression, nonfunctional thinking, attentional and interpretational bias of the participants were evaluated. The result of analysis reveals that social anxiety level, which is the basic measure of this study, significantly decreased in the D group compared with the DP group; however, this effect was not preserved in the follow up measurements. The findings are discussed.Araştırma sosyal kaygı belirtileri olan 84 üniversite öğrencisi ile yürütülmüştür. Katılımcılar bilişsel yanlılık değişmeleme grubu (D) ile plasebo kontrol grubu (DP) olmak üzere seçkisiz olarak iki gruba ayrılmışlardır. D grubundaki katılımcılar haftada iki gün olmak üzere sekiz seanslık bilgisayar başında gerçekleştirilen bir dikkat ve yorumlama yanlılığı değişimleme çalışmasına katılmıştır. DP grubundaki katılımcılar da değişimlemenin olmadığı bir çalışmaya katılmışlardır. Katılmcıların sosyal kaygı, kaygı, depresyon, işlevsel olmayan düşünce, dikkat ve yorumlama yanlılık düzeyleri değerlendirilmiştir. Analiz sonuçlarına bakıldığında çalışmanın ana ölçümü olan sosyal kaygı belirti düzeyi, D grubunda DP grubuna kıyasla son test ölçümünde anlamlı düzeyde azalma göstermiş, ancak bu etki takip ölçümlerinde korunmamıştır.

Skin Cancer-Related Health Behavior Interventions in the Context of the Health Belief Model

The incidence of skin cancer is increasing around the world every year. Although there are many reasons for the occurrence of skin cancer, UV radiation caused by sunlight is seen as the most important factor. Therefore, reducing exposure to UV radiation should be a top priority for skin cancer prevention. In addition, different demographic features also affect the amount of UV exposure. These include age, gender and professional groups. On the other hand, people can be exposed to UV radiation voluntarily. Sunbathing or using tanning devices can be shown as examples for this. For these reasons, interventions to reduce exposure to UV radiation should focus on demographic features and the desire to tan. At the same time, it is emphasized in the literature that theory-based and systematic interventions are more effective than others. In this context, we think that the Health Belief Model, which is an effective psychosocial model for health behaviors, will be useful in developing sun protection behaviors. In this review, interventions based on the Health Belief Model in the context of tanning behavior, age, gender, and outdoor activities for the prevention of skin cancer and the improvement of sun protection behaviors have been discussed

An Investigation of Transition Flow in Porous Media by Event Driven Molecular Dynamics Simulation

Aim of this study is to investigate the properties of mono-atomic gas flow through the porous medium by using Event-Driven Molecular Dynamics (EDMD) simulation in the transition regime. The molecules and the solid particles forming the porous structure were modelled as hard spheres hence molecule trajectories, collision partners, interaction times and post-collision velocities were calculated deterministically. The porous medium is formed of spherical particles suspended in the middle of the channel and these particles are distributed into the channel in a regular cubic array. Collisions of gas molecules with porous medium were provided by means of the specular reflection boundary condition. A negative pressure boundary condition was applied to the inlet and outlet of the porous media to ensure gas flow. Porosity, solid sphere diameter and Knudsen number (Kn) were initially input to the simulation for different Cases. Thus, the effects of these parameters on mass flow rate, dynamic viscosity, tortuosity and permeability were calculated by EDMD simulation. The results were compared with the literature and were found to be consistent

THE EFFECT OF MASSAGE ON SOME RECOVERY PARAMETERS

The aim of this study was investigate the effect of total classic body massage on some recovery and circulation parameters. Fourteen non-athlete physically active male university students voluntarily participated in the study. Participants randomly divided into two group Massage Group (MG) and Control Group (KG). All participants were informed about the purpose of the study, food consumption and not join the exercise before the test. 30 second Wingate Test protocol was used as exhaustive exercise. Heart Rate (KAH), systolic (SKB) and diastolic (DKB) blood pressures and blood lactate measured immediately after and 15 min recovery after exhaustive exercise. During 15 min recovery, total classic body massage was applied to MG group. Passive recovery was applied to KG group. The Shapiro Wilk Test of normality was used to determine if the data were normally distributed. Pair Sample T-Test was used for data’s were normally distributed, Wilcoxon Signed Ranks Test was used for data’s were not normally distributed. All analyses were set at p.05). Both groups blood lactate levels were significantly decreased (MG; t = 4.47, p = .004; KG; t = -2.36, p = .018). Blood lactate levels were determined as -51.60% and -24.63% on MG group and KG group respectively. Consequently, the total classic body massage thought to be effective on lactate removal level in short period of recovery
