Advancing the high-quality development of family physician-contracted service is an inevitable trend of deepening the reform of medicine and healthcare system under the new situation. How to strengthen the construction of family physician team and improve the quality and efficiency of contracted service has become an urgent problem to be solved.

To investigate the current state of team interaction among family physician team members and to explore its impact on job performance.

From October to December 2021, a questionnaire survey was conducted among family physician team members from primary healthcare institutions in Qianjiang, Hubei and Changsha, Hunan by combining convenience sampling and cluster sampling. The questionnaires covered basic information, team interaction, and job performance of family physician team members. Scores for each dimension of team interaction were analyzed, and hierarchical linear regression was used to examine its impact on job performance.

A total of 593 questionnaires were distributed and collected, with 580 valid responses (97.81%). There were significant differences in the scores of leadership effectiveness, task interaction, task monitoring, team support, and job performance among family physician team members of different genders (P<0.05). Significant differences in leadership effectiveness, task interaction, and task monitoring were noted across age groups (P<0.05). Significant differences in leadership effectiveness and task monitoring were also observed among members with different educational backgrounds (P<0.05). Task monitoring (β=0.201, P<0.001), cohesion (β=0.255, P<0.001), and interpersonal trust (β=0.236, P<0.001) all had significant positive effects on job performance.

Family physician team members reported relatively high overall scores for team interaction. Three dimensions of interaction—task monitoring, cohesion, and interpersonal trust—were found to positively impact job performance. Therefore, it is recommended to optimize the structure of family physician teams, enhance effective interaction and emotional support, and strengthen the management of team interaction.

调查家庭医生团队成员互动行为现状，探究其对工作绩效的影响。

于2021年10—12月，结合便利抽样法和整群随机抽样法，对湖北省潜江市和湖南省长沙县基层医疗卫生机构中参与家庭医生签约服务的团队成员进行问卷调查，问卷内容包括家庭医生团队成员基本情况、互动行为及工作绩效量表。分析家庭医生团队成员互动行为各维度得分情况，采用层次线性回归验证其对工作绩效的影响。

共发放并回收问卷593份，有效问卷580份（97.81%）。不同性别的家庭医生团队成员的领导效能、任务互动、任务监测、团队支持和工作绩效得分比较，差异有统计学意义（P<0.05）。不同年龄的家庭医生团队成员领导效能、任务互动和任务监测得分比较，差异有统计学意义（P<0.05）。不同文化程度的家庭医生团队成员领导效能和任务监测得分比较，差异有统计学意义（P<0.05）。家庭医生团队成员互动行为的任务监测（β=0.201，P<0.001）、凝聚力（β=0.255，P<0.001）和人际信任（β=0.236，P<0.001）3个维度对工作绩效的正向作用显著。

家庭医生团队成员的互动行为整体得分较高，其中任务监测、凝聚力和人际信任3个维度互动行为对工作绩效有积极影响。因此，建议优化家庭医生团队结构，着力提升有效互动和情感支持水平，并加强家庭医生团队成员互动行为管理。
