媒介使用对医学生职业期望的影响——基于媒介参与行为的中介效应分析

The impact of media usage on the career expectations of medical students:an analysis of mediation effect based on media participation behavior

目的了解医学生专业学习相关的媒介使用情况、媒介参与行为、职业期望,探讨媒介参与行为在媒介使用与职业期望间的中介作用,提出促进医学职业认同与职业准备的媒介赋能教育策略。方法借鉴信度效度俱佳的量表,设计符合本研究的调查问卷,对人口统计学特征和媒介使用、媒介参与行为、职业期望进行测量,自变量、中介变量、因变量均采用5刻度Likert量表。按照便利抽样和滚雪球抽样,通过在线填写问卷对全国范围内的医学生展开调查。结果1040名受访者与专业学习相关的媒体使用为(2.844±0.830)分,媒介参与行为为(2.760±0.699)分,职业期望为(2.666±0.767)分。医学生媒介使用与媒介参与行为(r=0.217,P<0.01)、职业期望(r=0.122,P<0.01),媒介参与行为与职业期望(r=0.523,P<0.01)均呈显著正相关;媒介参与行为作为中介变量,在媒体使用影响职业期望中作用显著,中介效应占比为26.32%。结论应借鉴参与式信息生产逻辑、具身认知的新方式、职业生涯周期规律,以媒介赋能医学生的综合素养体系,升级混合教学模式,完善医学人文教育链条,达到提升医学生职业期望的目的。

Objective:To investigate the media usage situation,media participation behavior,and career expectations related to medical students’professional learning,and explore the mediating effect of media participation behavior between media usage and career expectations,this paper proposed strategies for empowering education through media of promoting medical career identity and career preparation.Methods:Drawing on some scales with excellent reliability and validity,a questionnaire that is suitable for this study was designed to measure demographic characteristics,media usage,media participation behavior,and career expectations.The independent,mediating,and dependent variables were all measured using a 5-scaled Likert scale.According to convenience sampling and snowball sampling,medical students nationwide were surveyed through questionnaires filled in online.Results:For 1,040 respondents,the scores of media usage related to professional studies,media participation behavior,and career expectations were(2.844±0.830),(2.760±0.699)and(2.666±0.767),respectively.There were significant positive correlations among medical students between media usage and media participation behaviors(r=0.217,P<0.01),career expectations(r=0.122,P<0.01),as well as media participation behaviors and career expectations(r=0.523,P<0.01).Media participation behaviors,as a mediating variable,played a significant effect in the impact of media usage and career expectations among medical students,with a mediating effect accounting for 26.32%.Conclusions:The logic of participatory information production,new ways of embodied cognition,and the rules of the career life cycle should be drawn upon to empower the comprehensive quality of medical students through media,upgrade the blended teaching mode,improve the medical humanities education chain,and achieve the goal of enhancing the career expectations of medical students.
