The loneliness experience of college freshmen is closely related to their physical and mental
health. Without giving attention and intervention to the strong loneliness experience, it is easy to cause
their adaptive ability to be impaired. Therefore, this study includes two parts: In study one, 1260 freshmen
from a college in Sichuan were tested with the family rearing style Scale, Loneliness Scale and Connor-
Davidson Resilience Scale, and the relationship model between the three variables was tested with the
collected data to verify the mediating effect of resilience on the relationship between family rearing style
and loneliness. In the second study, 8 times group counseling intervention programs were designed for
college freshmen’s loneliness, and 40 subjects with high loneliness were randomly selected and divided
into experimental group and control group. Based on the two parts of the study, the following results were
obtained: (1) there were pairwise significant correlations between family rearing style, loneliness and
psychological resilience; Resilience played a partial mediating role in the effect of family rearing style on
loneliness; (2) After the intervention, there was a significant difference in the sense of loneliness between
the experimental group and the control group, and the level of loneliness in the experimental group was
significantly lower than that in the control group. In conclusion, family rearing style not only directly
affects the loneliness of the subjects, but also indirectly affects the loneliness of the subjects through
psychological resilience, and group counseling is one of the effective ways to improve the adaptation level
and reduce the loneliness of college freshmen.
