Curvilinear Effects of Extraversion on Socialization Outcomes Among Chinese College Students

Extraversion and low introversion more equivalent to high introversion in depression during COVID-19

OBJECTIVE

This study investigated whether forms of extraversion-introversion produced different depression-related outcomes before and during the COVID-19 pandemic.

METHOD

One-way MANCOVAs were conducted to investigate the relationship between extraversion-introversion and depressive symptoms. These data were sourced from the NLSY97, consisting of 4846 individuals born between 1980 and 1984.

RESULTS

During pre-pandemic periods, high introversion increased the risk of depressive symptoms. During the pandemic, the risk for depressive symptoms was more equivalent, or less predominately high-introvert-based, among extraverted/low introverted and high introverted subjects.

CONCLUSIONS

Extraversion/low introversion was linked with increased depression, relative to high introversion, during the pandemic. The findings raise significant questions about how individuals with distinct personality traits may experience changes in their psychological well-being during challenging public health events.

Moderated serial mediation effects of adaptation problems, academic stress, and interpersonal relationships on the sleep quality of early-year university students

Purpose

Due to heightened anxiety levels, sleep disorders become more prevalent among university students. This study, centered on adaptive capacity in early-year university students, aimed to explore the underlying mechanisms through which anxiety affects sleep quality.

Methods

Between February 2023 and June 2023, a cohort of first- and second-year university students (mean age 18.8 years) from Hunan Province, China, took part in an online survey. Anxiety was assessed using the Self-rating Anxiety Scale; adaptation problems, academic stress, and interpersonal relationships were assessed using the Adolescent Self-Rating Life Events Checklist; and sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). A moderated serial mediation model, based on Hayes' Model 92, was used to assess the hypothesized model.

Results

The survey resulted in 3,490 valid responses. Among respondents, 24% exhibited anxiety symptoms and 30.4% showed abnormal sleep patterns (i.e., PSQI score ≥ 8). The most significant path identified based on indirect effects was anxiety (β = 0.109), adaptation problems (β = 0.183), academic stress (β = 0.081), and sleep quality (all p-values < 0.001). Furthermore, interpersonal relationships moderated the effects of adaptation problems (β = -0.015, p < 0.001), academic stress (β = -0.012, p < 0.001), and anxiety (β = 0.003, p = 0.002) on sleep quality.

Conclusion

Elevated anxiety and sleep disorders are common among university students. Adaptive capacity may play a crucial role in sleep disorders among early-year university students. Interventions such as fostering strong interpersonal relationships in campus environments, may prove beneficial in improving academic performance and sleep quality.

Are social support, loneliness, and social connection differentially associated with happiness across levels of introversion-extraversion?

This study examines whether extraversion moderates the association between subjective happiness and measures of social connectedness using data from Canadian residents, aged 16+, recruited online during the third wave of the COVID-19 pandemic (21 April 2021-1 June 2021). To accomplish this aim we tested the moderating effect of extraversion scores on the association between Subjective Happiness scores and several social health measures: Perceived Social Support, Loneliness, social network size, and time with friends. Among 949 participants, results show that lower social loneliness (p < .001) and higher social support from friends (p = .001) and from family (p = .007) was more strongly correlated with subjective happiness for people with low extraversion compared to those with high extroversion. Anti-loneliness interventions should consider the need to promote social connections among individuals across the introversion-extraversion continuum.
