摘要:
目的 探讨医学生手机依赖和焦虑症状的交互作用及其与不确定心理压力的关联，为减少医学生不确定心理压力及开展干预提供参考。 方法 采用分层整群随机抽样法，于2022年11—12月抽取徐州医科大学共2 085名医学生，采用智能手机成瘾量表简版(SAS-SV)、广泛性焦虑障碍量表(GAD-7)和不确定压力量表进行问卷调查。采用Logistic回归分析医学生手机依赖和焦虑症状对不确定心理压力的影响，并采用相乘和相加交互作用模型分析其交互作用。 结果 医学生不确定心理压力的检出率为26.2%。在调整性别、性取向等混杂因素后，Logistic回归分析结果显示，手机依赖和焦虑症状均与医学生不确定心理压力有关联[OR(95%CI)值分别为4.05(3.22~5.10)和9.80(6.84~14.03)，P值均 < 0.05]。交互作用分析结果显示，手机依赖和焦虑对不确定心理压力无相乘交互作用，但具有相加交互作用[OR(95%CI)=39.59(24.60~62.74)，RERI(95%CI)=26.68(8.07~45.28), AP(95%CI)=0.67(0.48~0.87), S(95%CI)=3.24 (1.73~6.08)，P值均 < 0.05]。 结论 医学生的手机依赖和焦虑症状与不确定心理压力相关且具有协同作用。降低医学生手机依赖程度同时缓解其焦虑情绪，对于减少不确定心理压力的发生可能具有积极作用。 Abstract:Objective To explore medical students' mobile phone dependence and anxiety symptoms, as well as the association between their interaction and uncertainty stress, so as to provide a reference for uncertainty stress prevention and intervention in medical students intervention. Methods From November to December 2022, a total of 2 085 medical students from a medical university were selected by using stratified cluster random sampling. A questionnaire survey was conducted by using the Smartphone Addiction Scale-Short Version(SAS-SV), Generalized Anxiety Disorder-7 (GAD-7), and Uncertainty Stress Scale. Logistic regression was used to analyze the influence of mobile phone dependence and anxiety symptoms on uncertainty stress in medical students, and multiplicative and additive interaction models were employed to analyze their interaction. Results The detection rate of uncertainty stress was 26.2%. After adjusting for gender, age and other confounders, Logistic regression analysis showed that both mobile phone dependence and anxiety symptoms were related to uncertainty stress in medical students [OR (95%CI)=4.05(3.22-5.10), 9.80(6.84-14.03), P < 0.05]. Interaction analysis revealed no multiplicative interaction between mobile phone dependence and anxiety on uncertainty stress; however, additive interactions were observed [OR(95%CI)=39.59(24.60-62.74), RERI (95%CI)=26.68(8.07-45.28), AP(95%CI)=0.67(0.48-0.87), S(95%CI)=3.24(1.73-6.34), P < 0.05]. Conclusions Mobile phone dependence and anxiety symptoms in medical students are related to uncertainty stress, and they have a synergistic effect. Reducing medical students' dependence on mobile phones and alleviating their anxiety will help reduce the occurrence of uncertainty stress. -
