Objective: Although health and wellness behaviors are associated with positive body image, research is limited regarding the relationship between sleep and positive body image. We propose that negative affective states may link sleep and body image. Specifically, we examined whether better sleep may relate to positive body image through reductions…

This randomized controlled study examined the effects of creating open circle mandalas with divergent instruction type (distraction and reflection) and medium type (resistive and fluid) on state anxiety, mood, and mindfulness. The design followed a 2 (instruction type) x 2 (medium type) x 3 (time) mixed experimental design. Reflective writing…

Worry is an important mediator in the relation between stressors and health. This pilot study examined whether a smartphone-based in time worry-reduction training was feasible and improved physiological health (i.e. increased heart rate variability [HRV]). A total of 26 high-worriers were randomised to an experimental or active-control condition…

Peer review enhances student knowledge acquisition and the ability to meaningfully apply that knowledge. Formative assessment is the source of much of the positive effect of the peer review process. This evaluation investigated the affective experiences of graduate students as they navigated the writing of their research proposals. The authors…

In science education, dissections of animals are an integral part of teaching, but they often evoke negative emotions. We aimed at reducing negative emotions (anxiety, negative affect [NA]) and increasing positive affect (PA) and self-efficacy by an experimental intervention using a predissection video to instruct students about fish dissection.…

The purpose of the present study was to examine the psychometric properties of the Chinese version of the Acceptance and Action Questionnaire-II (AAQ-II) across two samples of Chinese college students (n = 183 and n = 366) and a sample of elite Chinese athletes (n = 330). Exploratory and confirmatory factor analyses supported the existence of a…

The aim of this study was to validate a Spanish version of the Cognitive Emotion Regulation Questionnaire (CERQ-S), originally developed by Garnefski, Kraaij, and Spinhoven. To date, it is the only available instrument that permits a conceptually pure quantification of cognitive strategies of emotional regulation. A sample of 615 students (25…

Our work is based on two premises. The first is that affective factors (beliefs, attitudes, and emotions) influence teaching and learning mathematics, and problem solving in particular. The second is that initial teacher education is an important element in the process of improving overall educational practice. On this basis, our research group…
