AbstractThe literature shows that homesickness can have a negative impact on different areas of psychological functioning such as cognitive, emotional, behavioral, physical and social ones. The study, conducted on a sample of first-year university students, aimed to test a model hypothesizing that two distinct dimensions of homesickness, attachment to home and disliking university, could have both direct and indirect effects on their psychological distress and sleep difficulties. Two hundred and seventy-seven first-year students (70.4% Female) living away from home (mean age= 21.3, SD= 2.7) were included in the study and filled out questionnaires assessing homesickness, psychological distress and sleep difficulties. Structural Equation Model (SEM) analysis confirmed that the two homesickness dimensions worked differently since only the one relating to new place adjustment difficulties (i.e. disliking the university) resulted having both direct and indirect effects on students’ sleep difficulties. Although female students reported higher levels of psychological distress compared to males, the multi-group SEM analysis showed that the pattern of multivariate relationships linking the two dimensions of homesickness, psychological distress and sleep difficulties, was invariant across gender. The results of the present study suggest that university counselling and guidance services should quickly screen students experiencing homesickness and offer effective counselling programs focusing on enhancing their capacities to deal with the new academic environment.

Purpose: Private supplementary tutoring has been increasingly used by parents as part of wider strategies to assist their children’s education careers in China. With a theoretical lens of parentocracy, this article aimed to investigate the influential parental factors underlying the demand for private tutoring, focusing on parents’ socioeconomic resources and attitudes toward education. Design/Approach/Methods: This article drew upon data from the 2014 iteration of the China Family Panel Studies. Structural equation modeling (SEM) analysis was employed to explore the influences of parental factors. Findings: The SEM analysis confirmed that parental income, education, and aspirations on children’s education had both direct and indirect positive effects through the mediating factor of role construction on demand for tutoring. A multiple-group analysis was further conducted, and the difference in the patterns for urban and rural parents was explored. Parental occupation had no impact on demand for tutoring for rural parents but had both direct and indirect effects for urban parents. Both direct and indirect effects of household income on demand for tutoring were greater for urban parents than for rural parents. Originality/Value: This article examined the direct and indirect influences of parental factors on demand for private tutoring and explored the differences in patterns for urban and rural parents in a quantitative way. Findings have implications for education inequality.
