The Difficulties in Emotion Regulation Scale (DERS) is a widely used measure of emotion dysregulation. However, limited research has examined its factor structure and measurement invariance in cross-national samples. The present study tested competing measurement models and the measurement invariance of the DERS in university student samples from…

In Germany, there are no self-report questionnaires assessing emotion awareness in youth under the age of 16 years or simultaneously with emotion suppression. The "Emotion Expression Scale for Children" (EESC) measuring lack of emotion awareness and reluctance to express emotions in 10- to 15-year-olds can fill this gap. Goal of this…

This study sought to validate the Short Grit Scale (Grit-S), an instrument that measures perseverance and passion for long-term goals, among Chinese high school students. Confirmatory factor analyses revealed that the scale retains the two-factor structure of the original scale. The scale demonstrated satisfactory internal consistency and…

Using a sample of 348 middle school students, we gathered evidence regarding the internal consistency of scores, as well as the internal factor structure and convergent validity evidence for inferences from a self-report questionnaire called the Self-Regulation Strategy Inventory-Self Report. Confirmatory factor analysis revealed that the fit…

Among young adults and clinical populations, perceived inability to control internal and external events is associated with anxiety. At present, it is unclear what role perceived anxiety control plays in anxiety among older adults. The Anxiety Control Questionnaire (ACQ) was developed to assess one's perceived ability to cope with anxiety-related…

This dissertation consists of four chapters. Chapter 1 provides an introduction to the self-determination literature documenting the importance of promoting the self-determination of transition and secondary age students with disabilities, as well as a summary of research examining the self-determination of students with disabilities across…

Romantic relationships among young adults are rich with ambiguity and without a clear, universal progression emphasizing the need for active decision making. Lack of active decision making in romantic relationships can lead to increases in constraints (e.g. pregnancy, shared living space or finances) that promote the continuation of relationships…

The "Decision-Making Questionnaire" (DMQ) was developed and validated in order to examine the factors that affect decision making. The investigation was carried out with two samples, one of 170 participants and the other of 425 of both sexes. Each sample was divided into three age ranges: young students (18-25 years), adults (26-60…

The Regulatory Emotional Self-Efficacy (RESE) scale was developed to assess perceived self-efficacy in managing negative (NEG) and in expressing positive (POS) affect (G. V. Caprara & M. Gerbino, 2001). In this study of young adults, the factorial structure of the RESE scale was found to be similar in Italy, the United States, and Bolivia: In…
