Whether there is a difference in perceived social support (PSS) and related factors among college students from one- and multiple-child families was unclear.
We conducted a population-based, cross-sectional study between October 2017 and February 2018, randomly selected college students with siblings (n=5875; aged 19.41±1.99 years) and their counterparts without siblings (n=5175; aged 19.88±2.38 years), and then conducted an online questionnaire survey via a multi-stage cluster random sampling method. We applied the multidimensional scale of perceived social support (MSPSS) to evaluate PSS among college students. The multivariable logistic regression models were used to predict factors associated with low perceived social support in two student groups.
Our study found that there was a statistical difference of PSS between the sibling groups. Sex, single-parent family, irregular daily routine, prevalence of diseases or injuries and psychological distress were significantly associated with low PSS in both college students with and without siblings. Compared with single-child college students, single-parent family structure was associated with a higher odds ratio for low PSS in college students with siblings (ratio of odds ratio: 0.71, 95% confidential interval: 0.53-0.97).
Our study was a cross-sectional study design, and all participants in current study were from Wuhan city, Hubei Province. Hence, the sample is not representative of other regions in China.
Although a statistical difference of PSS between the sibling groups was found in our study, single-parent family structure was more strongly associated with low PSS in multiple-child students compared with single-child students.
独生子女家庭和多子女家庭的大学生感知社会支持（PSS）及其相关因素是否存在差异尚不清楚。
我们于 2017 年 10 月至 2018 年 2 月期间开展了一项基于人群的横断面研究，随机选取了有兄弟姐妹的大学生（n=5875；年龄 19.41±1.99 岁）和无兄弟姐妹的大学生（n=5175；年龄 19.88±2.38 岁），然后采用多阶段整群随机抽样方法进行在线问卷调查。我们采用多维感知社会支持量表（MSPSS）评估大学生的 PSS。多变量逻辑回归模型用于预测两组学生中与低感知社会支持相关的因素。
研究发现，有兄弟姐妹的大学生群体之间的 PSS 存在统计学差异。性别、单亲家庭、不规则的日常生活、疾病或伤害的发生率以及心理困扰与有兄弟姐妹和无兄弟姐妹的大学生的低 PSS 均显著相关。与独生子女大学生相比，单亲家庭结构与有兄弟姐妹的大学生低 PSS 的比值比相关（比值比：0.71，95%置信区间：0.53-0.97）。
本研究为横断面研究设计，且当前研究的所有参与者均来自湖北省武汉市，因此样本不能代表中国其他地区。
尽管本研究发现有兄弟姐妹的大学生群体之间的 PSS 存在统计学差异，但与独生子女大学生相比，单亲家庭结构与多子女学生的低 PSS 更密切相关。
