社会性奖赏问卷在大学生群体中的修订及应用

目的:在中国大学生群体中进行翻译并修订社会性奖赏问卷(Social Reward Questionnaire,SRQ),据此考察中国大学生的社会性奖赏水平。方法:采用方便取样法和滚雪球抽样法调查8275名大学生,以此来检验SRQ的问卷结构,并以大五人格简式版(Chinese Big Five Personality Inventory brief version,CBF-PI-B)的开放性、外向性、神经质维度以及奖励与惩罚敏感性问卷(The Sensitivity to Punishment and Sensitivity to Reward Questionnaire,SPSRQ)作为效标进行效度检验。结果:经分析后,中文版SRQ保留了原问卷的钦佩性、负性社交效价、被动性、社交性、性关系的五因素结构,共21条目,每个维度3~7个条目,累积方差解释率65.66%,各个因子的因子载荷为0.62~0.86。CFA结果为RMSEA=0.047,CFI=0.94,TLI=0.93,SRMR=0.047。SRQ总分及分维度的内部一致性信度为0.70~0.88、分半信度为0.71~0.89、重测信度(ICC)为0.75~0.94,问卷在不同性别学生之间具有完全的测量等值性(ΔCFI<0.01,ΔRMSEA<0.01)。结论:修订后的SRQ中文版具有较好的信度和效度,是测量中国大学生群体社会性奖赏的合适工具。

Case-finding for mental distress in primary health care: An evaluation of the performance of a five-item screening instrument

Background: There is an increased interest in developing better and more accurate methods to recognize and manage mental health problems in primary care settings. Abbreviated screening instruments for mental distress are useful tools for research and clinical practice. The present study seeks to investigate whether only a few questionnaire items from the Self-Reporting- Questionnaire-10 (SRQ-10) can be a robust method in the screening for Mental Distress in Primary Health care. Methods: We compared the screening accuracy of a short, five-item (SRQ-5) version of the SRQ-10 with that of the SRQ-20, General Health Questionnaire 12 (GHQ-12) using the DSM-IV axis as a gold standard and analyzed its performance in different diagnostic entities. We also assessed the correlation, sensitivity and specificity between the 4 instruments. All the instruments were administered to 400 primary health care attendees. Results: The estimated prevalence of mental distress was 13.6% in the study sample (Depression 11%, anxiety disorders 1.8%). The SRQ-5 was highly correlated to SRQ-10 (0.923, p < 0.001), SRQ-20 (0.764, p < 0.001) and only moderately correlated to GHQ-12 (0.417, p < 0.001). The SRQ-5 had high properties for identifying mental distress. The AUC for overall mental distress was 0.925 while that for depression and anxiety were 0.915 and 0.849 respectively. Conclusion: This validation showed that in moving from SRQ with 10 or 20 items to one with merely 5 items, we do not seem to lose the screening prowess of the instrument. The SRQ-5 represents a simplified and less time-consuming screening instrument with strong performance characteristics. We therefore recommend it for inclusion into existing patient assessment protocols, thus enhancing case finding at primary health care level.

中文学生版同胞关系问卷的效度和信度

目的:修订同胞关系问卷学生版并进行效度和信度检验。方法:选取吉林省五所中小学四年级到初二的二胎家庭学生703人,用中文学生版同胞关系问卷、长处与困难问卷(SDQ)、父母教养方式问卷(EMBU)进行测试,间隔11周后对其中213人进行重测。结果:问卷共36个条目分为温暖/亲密、冲突和争宠3个因子,累积方差贡献率为51.0%;验证性因子分析表明数据拟合良好(x^(2)/df=1.89,CFI=0.93,TLI=0.93,IFI=0.94,RMSEA=0.05);温暖/亲密、冲突、争宠得分均与效标正相关(r=0.37、0.32、0.41,均P<0.001)。3个因子的Cronbach a系数为0.95、0.87和0.84,重测信度为0.62,0.64和0.45。结论:中文学生版同胞关系问卷信效度良好,可作为我国文化背景下的学生同胞关系质量的测量工具。

Mental Distress among Medical Students in Khartoum, Sudan 2022

Background: Young adults in Sudan face numerous challenges that make it difficult for them to maintain their mental health. Due to the academic workload and performance expectations, medical students suffer from a high prevalence of mental distress. Objectives: to estimate the prevalence of mental distress among medical students and determine the associated factors. Methods: a cross-sectional survey was conducted among medical students in Khartoum, Sudan, using an electronic questionnaire. Mental distress was screened in the period from June 19 to July 30, 2022, using the self-reporting questionnaire (SRQ-20). Descriptive statistics in the form of frequencies and percentages were used to display data. Odds ratios (ORs) with a 95% confidence interval were estimated using univariate and multivariate logistic regression analysis to determine associations between mental distress and related factors. Results: A total of 432 valid responses were received with a mean age of 20.37. The Overall prevalence of mental distress (SRQ-20 > 8) in medical students was 241 (55.8%). The prevalence was significantly associated with gender (P-Value > 0.001), type of university (P-Value = 0.001), academic level of education (P-Value = 0.026), and family history of mental illness (P-value = 0.001). Conclusion: More than half of the medical students who were screened for mental distress had mental distress. Higher odds are associated with being a female student, attending a private university, studying at a higher academic level, and having a family history of mental illness. This study recommends a review of the academic processes and implementing institutional preventive strategies that target at-risk groups.

汶川地震灾民89例住院期间心理评估和干预

目的评估汶川地震灾民89例在住院期间的心理状况，探讨心理干预方法。方法对49例患者采用SRQ干预者评定，39例陪人SRQ自评。SRQ〉=8分为评定阳性。每例患者和评定阳性的陪人每周复评一次。对评定阴性的灾民采用心理健康教育，评定阳性的重点干预。帮助居丧者顺利度过悲哀期，帮助他们建立思考积极的应对方式，给予强有力的社会支持系统，辅以药物治疗。结果患者组SRQ阳性21例，陪人组SRQ阳性16例。患者和陪人SRQ无统计学差异。第二次SRQ评定较第一次低，差异具有统计学意义。第四次SRQ评定与第三次相比，差异不具有统计学意义。出现频率排前三位的精神症状均是易受惊吓，睡眠差，以及感觉不安、紧张或担忧。结论地震后患者和陪人都有一定比例的SRQ阳性率，对患者和陪人要同时予以关注。积极心理干预可以帮助灾民度过困难时期，心理状况迅速恢复到正常范围。

47名地震灾区患者情感反应状况分析

目的探讨灾区患者灾后转入他地诊治时的情感反应,为及时发现处理情绪问题提供依据。方法采用正性负性情绪量表及灾后心理健康自评问卷对47名地震灾区患者进行调查,并进行统计分析。结果以SRQ界值为界划分为两组,不同组别患者SRQ得分与负性情绪相关显著;不同组别患者正性情绪差异边缘显著(P=0.086),负性情绪差异有统计学意义(P<0.001)。结论地震灾区患者的情感痛苦水平与其情绪状态密切相关,应积极开展心理干预,降低受灾人群特别是受伤人群的心理损害。
