In the context of COVID-19, people face conditions of great stress and are susceptible to negative emotions such as worry, fear, and doubt. Therefore, the focus of epidemic prevention should be on mental health as well as physical health. It is important to pay attention to people's mental health while mitigating and controlling the epidemic. As an intervention to improve mental health, exercise behavior has attracted increasing attention from scholars due to its convenience and low cost. Therefore, the goal of this paper was to investigate the differences between characteristics related to linguistic expression and mental health indicators among different groups of Weibo users by constructing a Weibo exercise behavior user lexicon to explore the influence of exercise behavior on mental health. This study developed a user dictionary of exercise behavior, classified Sina Weibo users' exercise behavior, and established relevant systems to uncover the expressive characteristics of psychological vocabulary and behavioral vocabulary to explore the differences in expressive features related to psychological and behavioral vocabulary and mental health indicators among users who engage in different forms of exercise behavior during the period of COVID-19. As a result of an analysis of variance (ANOVA) conducted during the COVID-19 epidemic, (1) based on the constructed user lexicon of motion behavior in Weibo, the classification program exhibited good performance; (2) there were significant differences in the expressions of some lexical features among users who exhibited different motor behaviors; and (3) both nonphysical exercise and physical exercise behavior had positive relationships with some mental health indicators, but the mechanism associated with nonphysical exercise requires further exploration. This study provides a scientific online evaluation methodology and support for research concerning exercise and mental health during the COVID-19 epidemic.

Prisoners’ employment has received widespread attention from society. In this study, based on career construction theory and social cognitive career theory, 300 male prisoners were selected as the research sample, and questionnaires were used for data collection. The results show that in the relationships between extroversion, openness, neuroticism, and perception of career barriers, and prisoners’ career adaptability plays a mediating role. When extroversion, openness, and neuroticism are predictor variables, the socioeconomic status of prisoners plays a moderating role in the predictive effect of career adaptability on the perception of career barriers. Specifically, compared with individuals with low and medium socioeconomic statuses, the negative effect of career adaptability on the perception of career barriers was stronger at high socioeconomic status levels.
