大学生处于从青少年末期向成年早期的过渡阶段，其父母的家庭教养行为也将发生相应的变化。以往大量研究发现，父母控制尤其是心理控制会对亲子关系造成不良影响，但在大学生群体中进行，并且侧重于亲子亲密感的研究仍然较少。本研究采用问卷法与访谈法相结合的形式，探究父母控制及其变化对大学生感受到的亲子亲密感的影响。

研究一以324名大一到大四学生为研究对象，其中男生175人(54.0%)，女生149人(46.0%)，独生子女173人(53.4%)，非独生子女151人(46.6%)，采用问卷法，探究父母控制水平与亲子亲密感的相关性，以及父母权威认同和双元孝道的调节作用。结果表明，父母双方的心理控制、行为控制均能显著负向预测亲子亲密感，父母权威认同仅在母亲心理控制和母子亲密感之间具有显著的负向调节作用，权威型孝道在父母双方的心理控制、行为控制和亲子亲密感之间均具有显著的负向调节作用，相互型孝道在父母双方的心理控制、行为控制和亲子亲密感之间均不存在调节作用。

研究二在研究一的基础上，以7名18-25岁大学生为研究对象，其中男生3人，女生4人，独生子女5人，非独生子女2人，通过半结构化访谈形式探究父母控制在子女进入大学前后的变化对亲子亲密感的影响，以及子女对这一变化的具体看法。结果显示父母控制情况在子女进入大学后一般会减少或发生变化，但亲子亲密感的变化方向仍受更多其他因素影响。

College students are in the transition stage from late adolescence to early adulthood, and their parents' rearing patterns will also change accordingly. However, research conducted specifically among college students and focusing on parent-child closeness is still scarce. This study uses the combination of questionnaire and interview method to explore the impact of parental control and its changes on the perceived parent-child closeness among college students.

In study 1, 324 freshmen to seniors were selected as subjects, including 175 male(54.0%), 149 female(46.0%), 173 only children (53.4%) and 151 non-only children (46.6%). Questionnaire method was used to investigate the correlation between parental control and parent-child closeness, as well as the moderating roles of parental authority identification and dual filial piety. Results showed that both psychological control and behavioral control could significantly negatively predict parent-child closeness. Parental authority identification only had a significant negative moderating effect between mother's psychological control and mother-child closeness. Authoritative filial piety had a significant negative moderating effect between psychological control, behavioral control, and parent-child closeness for both parents. However, reciprocal filial piety did not exert any moderating effect.

Based on study 1, Study 2 employed semi-structured interviews with seven college students aged 18-25, including three males and four females, with five only children and two non-only children. The interviews aimed to explore the impact of changes in parental control before and after children enter university on parent-child closeness, as well as the specific views of the children on these changes. The results indicated that parental control typically decreases or changes after children enter university, but the direction of change in parent-child closeness is influenced by various other factors.
