Family physician-contracted service is an important way to change the mode of primary health care, and it is also the key and breakthrough to realize tiered diagnosis and treatment. How to strengthen the construction of family physician team and thus improve job satisfaction has become an urgent problem.

To explore the relationship between the network structural characteristics within family physician team and job satisfaction at the team level, and to provide a reference for strengthening the construction of family physician team.

From October 2021 to December 2023, we combined convenience sampling and cluster sampling to conduct field research on family physician teams in Qianjiang, Hubei, Changsha, Hunan and Nanyang, Henan. The Family Physician Team Members' Basic Information Questionnaire, the Family Physician Team Interaction Network Questionnaire and the Family Physician Team Job Satisfaction Scale were used to collect data. We used hierarchical linear regression analysis to verify the impact of the network density and centralization within family physician team on job satisfaction.

The transition processes of family physician team showed obvious network structure characteristics of low density (0.29±0.11) and high centralization (0.88±0.19). The average job satisfaction score of family physician team was (20.30±2.42), which was moderately high. The results of the hierarchical linear regression analysis showed that the centralization of transition processes positively affected job satisfaction (β=0.576, t=7.091, P<0.001) ; the density of transition processes positively affected job satisfaction (β=0.228, t=2.478, P<0.05) ; the density of action processes positively affected job satisfaction (β=0.324, t=2.624, P<0.05) ; the density of interpersonal processes positively affected job satisfaction (β=0.368, t=3.549, P<0.001) .

There is room for optimizing the network structural characteristics within family physician team in Central China. The network density and centralization of family physician teams have positive effects on job satisfaction. It is recommended to improve the internal collaboration mechanism and optimize the centralized network structure within family physician team.

家庭医生签约服务是转变基层医疗卫生服务模式的重要途径，也是实现分级诊疗的关键和突破口。如何加强家庭医生团队建设，进而提高工作满意度成为亟待解决的问题。

从团队层面探究家庭医生团队内部互动网络结构特征与工作满意度的关系，为加强家庭医生团队建设提供参考。

于2021年10月—2023年12月采用便利抽样法和整群随机抽样法对湖北省潜江市、湖南省长沙县和河南省南阳市的家庭医生团队开展实地调研，使用家庭医生团队成员基本情况调查表、家庭医生团队内部互动网络调查表和家庭医生团队工作满意度量表收集数据，并采用层次线性回归分析验证家庭医生团队内部互动网络密度和网络中心势对工作满意度的影响。

家庭医生团队转化过程呈现出明显的低密度（0.29±0.11）、高中心势（0.88±0.19）的网络结构特征；家庭医生团队工作满意度平均得分为（20.30±2.42）分，呈中等偏上水平；层次线性回归分析结果显示，转化过程网络中心势正向影响工作满意度（β=0.576，t=7.091，P<0.001）；转化过程网络密度正向影响工作满意度（β=0.228，t=2.478，P<0.05）；执行过程网络密度正向影响工作满意度（β=0.324，t=2.624，P<0.05）；人际过程网络密度正向影响工作满意度（β=0.368，t=3.549，P<0.001）。

华中地区家庭医生团队内部互动存在优化空间，家庭医生团队内部互动网络密度和网络中心势对工作满意度具有积极作用。建议完善家庭医生团队内部协作机制、优化集权网络结构。
