Childhood stress affects physical and mental health, making its proper assessment crucial. While several stress questionnaires for youth are available, their psychometric quality is questionable.

Peer victimization is critical to study in early and middle childhood as it is associated with adjustment and behavioral problems in adolescence. Because much victimization occurs outside of the purview of adults, self-report measures are important assessments of this construct; however, there is limited evidence for the psychometric properties of…

Little is known about whether a widely used mindfulness measure in adults--the Five Facet Mindfulness Questionnaire (FFMQ)--is also reliable and valid in adolescents. The current study evaluated the psychometric properties of a 20-item short-form FFMQ in a sample of 599 high school students (M[subscript age] = 16.3 years; 49% female) living in the…

The purpose of the present study was to examine the factorial and convergent validity of the German translation of the Exercise Identity Scale (EIS; Anderson & Cychosz, 1994). We introduce a bifactor model as a possible alternative to the previously discussed one- and two-factor models. Using an online study with 530 participants, our results…

The scale was administered to 638 students in…

There has been a growing need felt by practitioners, researchers, and evaluators to obtain a common measure of science engagement that can be used in different out-of-school time (OST) science learning settings. We report on the development and validation of a novel 10-item self-report instrument designed to measure, communicate, and ultimately…

The nutrition environment in schools can influence the risk for childhood overweight and obesity, which in turn can have life-long implications for risk of chronic disease.
