Prediction of relationship quality by social isolation and its matching in college couples / 中华行为医学与脑科学杂志

ABSTRACT

Objective To explore the relationship between social isolation ( SI) and relationship quality(RQ) of college couples at individual and matching level. Methods The SI and average RQ of 187 college couples were surveyed,and a quadratic polynomial regression with response surface analysis was used to conduct the cross-sectional study. Results The scores of SI were ( 1.81± 0.89) in males and ( 1.71 ± 0.80) in females,while the score of average RQ was ( 5.34 ± 0.89).SI had a negative linear correlation (maler＝－0.21,P＜0.01; femaler＝－0.17,P＜0.05) and a U-shaped correlation (maleβ＝0.163,P＜0.01;femaleβ＝0.186,P＜0.01) with RQ.When SI of the two partners was similar,their matching predicted RQ negatively (β＝－0.62,P＜0.01) and had a U-shaped correlation (β＝0.25,P＜0.01) with RQ,but when they were not,their matching only had a U-shaped correlation (β＝0.45,P＜0.01) with RQ.Conclusion Individ-uals in a relationship or couples may have higher RQ when SI is high.When the couple’s SI is quite differ-ent,the bigger the difference,the higher RQ might be.
