The mainstream psychology has mostly focused on the negative factors that threaten human mental health. With the emergence of positive psychology approach, the human strengths have started to be studied and the number of studies on the issue of happiness and well-being has increased. The aim of this research is to reveal the level of prediction for psychological well-being by the variables of gratitude, hope, optimism and life satisfaction. Method: Research sample consisted of 510 students from various faculties and departments of four different universities. The study group consisted of 359 female (70.4%) and 151 male (29.6%) university students. The age range of participants varied between 17 and 30.

Facebook addiction is a growing issue that has increasingly attracted the attention of clinicians and researchers in a variety of countries and cultures. Relying on the Cognitive-Behavioral Model for Pathological Internet Use, and in a sample of Turkish undergraduates, we investigate whether mindfulness might account for how self-esteem and psychological problems (depression, anxiety, and stress) connect to Facebook addiction. A total of 298 college students completed measures of Facebook addiction, self-esteem, mindfulness and psychological problems, which we analyzed using path analysis, testing various models of how Facebook addiction might be predicted by these factors. We found that Facebook addiction was positively associated with psychological problems and negatively associated with self-esteem and mindfulness, with mindfulness fully accounting for the association between psychological problems, self-esteem and Facebook addiction. These results support the role of mindfulness in the prevention of Facebook addiction and the treatment of addicted individuals. This study also helps clarify previous research connecting mindfulness to Internet addiction, and extends those findings cross-culturally to a Turkish context.

The current study aims to investigate the relationship among problem solving, hope, and self-efficacy and to test a model for determining the role of self-efficacy in the relationship between problem solving and hope. It adopted convenience sampling and consisted of 494 undergraduate students (369 females; 125 males). The Hope Scale, General Self-Efficacy Scale and Problem Solving Inventory were applied in order to collect the data. Pearson correlation analysis and two-step Structural Equation Modelling were used for data analysis. Findings revealed that while a high level of positive correlation existed among problem solving, self-efficacy and hope, a moderate positive relationship was found between self-efficacy and hope. As a result of Structural Equation Modelling, self-efficacy was found to be significantly predicted by problem solving whereas hope was observed to be significantly predicted by problem-solving and self-efficacy. In addition, mediation analysis demonstrated that the relationship between problem solving and hope emerged through the development of self-efficacy. As a result, this paper exhibited that individuals with developing problem solving ability had also developing self-efficacy, which in turn leads to an increase in hope. Therefore, it may be effective to take into account the components that will improve individuals' problem solving skills and perceptions about themselves while conducting the studies to raise the hope level, which is an important concept of psychological health.

Bu araştırmanın amacı spor alanında öğrenim gören öğrencilerde spora bağlı olarak gözlenen tükenmişliğin incelenmesi amacıyla geliştirilen Spor Tükenmişliği Envanterini Türkçe’ye uyarlamaktır. Bu amaçla Sorkkila, Ryba, Aunola, Selänne ve Salmela-Aro (2017) tarafından geliştirilen 10 madde ve üç alt boyuttan oluşan Spor Tükenmişliği Envanteri Türkçe’ye uyarlanarak, geçerlik ve güvenirlik çalışması gerçekleştirilmiştir. Araştırma verileri beden eğitimi ve spor alanında öğrenim gören 250 (98 kadın %39.2, 152 erkek %60.8) üniversite öğrencisinden toplanmıştır. Envanterin yapı geçerliği DFA işlemi ile test edilmiş ve modelin geçerliği uyum indeksleri ile değerlendirilmiştir. Envanter için hesaplanan uyum iyiliği katsayıları ise χ2/Sd= 3.21; RMSEA= .094; GFI= .91; AGFI= .84; CFI= .95, IFI= .95; NFI= .92 ve NNFI= .92 olarak hesaplanmıştır. Ayrıca ölçme aracının uyum geçerliği ve ayırt edici geçerlik çalışmaları gerçekleştirilmiştir. Uyum geçerliği kapsamında Beck Depresyon Envanteri ile Spor Tükenmişliği Envanteri arasındaki ilişki hesaplanmıştır. Ayırt edici geçerlik çalışması kapsamında ise Rosenberg Özsaygı Ölçeği ile Spor Tükenmişliği Envanteri arasındaki ilişki incelenmiştir. Ayrıca envanterin güvenirlik düzeyinin belirlenmesi için Cronbach alfa iç tutarlılık katsayısı hesaplanmış, Cronbach alfa iç tutarlılık katsayısının ölçme aracının tümü için 0.81, Tükenme boyutu için 0.61, Duyarsızlaşma boyutu için 0.69 ve Yetersizlik boyutu için 0.61 olduğu görülmüştür. Spor Tükenmişliği Envanteri’nin spor alanında öğrenim gören üniversite öğrencilerinin spor tükenmişliği düzeylerini ölçmede geçerli ve güvenilir bir ölçme aracı olduğu söylenebilir. Araştırmadan elde edilen bulgular ilgili alanyazın ışığında tartışılarak uygulayıcılara, gelecekteki araştırmacılara ve ruh sağlığı alanına ilişkin öneriler sıralanmıştır.
