The aim of the present study was to develop and provide evidence for the validity of a new measure of adolescent students' psychological need satisfaction at school, using a sample of Chinese students. We conducted four studies with four independent samples (total n = 1872). The first study aimed to develop items for the new instrument and to ascertain its factorial structure using exploratory factor analysis procedures. The second study aimed to examine the instrument's factorial structure using confirmatory factor analysis procedures as well as to assess its internal consistency reliability, convergent and divergent validity. The third study aimed to assess its measurement invariance across gender and age. The fourth study aimed to test its test–retest reliability over time and predictive validity. These preliminary results showed that the new instrument has promising psychometric properties. The potential contributions of the new instrument for future research and educational practices were discussed.

This study investigated the potential mediating roles of resilience and social support in the relationship between stress and life satisfaction. A total of 426 individuals, who have substance use disorder, from the Shifosi and Dalianshan rehabilitation facilities in China participated in the study. They were tested using the Perceived Stress Scale, Multidimensional Scale of Perceived Social Support, Connor–Davidson Resilience Scale, and Satisfaction with Life Scale. Results showed that the serial multiple mediation of social support and resilience in the relationship between stress and life satisfaction was significant. Furthermore, the findings corroborate the important roles of perceived social support and resilience in alleviating stress. Finally, we discussed ways to enhance the life satisfaction for individuals who have substance use disorder and analyzed the limitations of this study.
