This article describes the development and validation of the Attitudes toward Sustainable Development scale, a quantitative 20-item scale that measures Italian university students' attitudes toward sustainable development. A total of 484 undergraduate students completed the questionnaire. The validity and reliability of the scale was statistically tested by computing the KMO and Bartlett tests and via an exploratory factor analysis, descriptive statistics, Cronbach's alpha, a confirmatory factor analysis and a multi-group invariance testing. The results of the principal components factor analysis show that the scale consists of the following four dimensions, with five items in each: environment, economy, society and education. The overall structure and measurement of the scale are confirmed by the confirmatory factor analysis and by the multi-group invariance testing. Internal reliability, which was found using Cronbach's alpha, varies between .660 and .854. The results show that the instrument meets the validity and reliability criteria. To demonstrate its utility, the scale was applied to detect differences in sustainable development attitudes among students pursuing degrees in psychology and in agriculture. Relevant differences were detected for the dimensions of environment and society. The Attitudes toward Sustainable Development scale could be useful for understanding the ways in which students think about sustainability issues and could be used to investigate the relationship between sustainability attitudes and other variables.

Music performance anxiety (MPA), a condition common among musicians, consists of an anxious state characterized by cognitive, psychological, and physiological arousal. Musicians often establish strategies for coping with MPA. The aim of the current study is to analyze the correlation between MPA factors and coping strategies, and to determine the relevance of coping strategies and other variables, such as gender, experience, and weekly hours of individual music practice, in predicting MPA. Data on MPA and coping strategies were collected using two questionnaires: the Performance Anxiety Inventory (PAI) and the Coping Orientation to Problems Experienced-New Italian Version (COPE-NVI). The participants were 171 musicians divided into the following two groups: 97 advanced music conservatory students and 74 professional musicians. The results indicate that coping strategies based on demand of social support and avoidance strategies have a positive correlation with MPA. Advanced students reported higher levels of MPA than professional musicians. In addition, regression analysis provides evidence that variance in MPA can be explained in part by experience (professional musicians versus advanced students), hours of individual practice per week and coping strategies based on social support and avoidance strategies. The findings underscore the importance of understanding processes involved in MPA and the need to learn adaptive strategies for coping with stressful events.
