Raw data from "Higher socioeconomic status predicts less adolescent depression".sav

Participants were 652 adolescents (age range: 11-20 years old, <i>M</i>_age =14.55 years, <i>SD</i> = 1.82; 338 boys (51.80%)) from two junior and two senior high schools in Wuhan, China. They completed questionnaires measuring family socioeconomic status (measured by the Family Affluence Scale), perceived social support (measured by the Multidimensional Scale of Perceived Social Support) , optimism (assessed by the Chinese version of the Life Orientation Test-Revised), and depression (measured by the Center for Epidemiologic Studies Depression Scale). Our research plan, questionnaires and the appropriate consent letters to students and their parents were submitted to the university’s Ethical Committee for Scientific Research, then examined by specialists and finally approved by the Ethical Committee. After obtaining the approval, we visited the selected school principals, handed out copies of questionnaires and consent letters, and asked for their cooperation. Then classroom teachers sent electronic consent letters to parents about the purpose of the research, the importance of the adolescents’ involvement and the voluntary nature of participation by the online Family-School Communication System and asked for parents’ support and permission. Students took home the printed consent letters that had to be signed by the students’ guardians. Classroom teachers also distributed printed consent forms to students and asked for their participation. Students with parental consent who also assented to participate were allowed to take part in the survey. A packet of self-report questionnaires was administered to students in groups of 40-50 at a time in those selected classes. Trained graduate students of psychology explained the requirements of the questionnaires using standard instructions that also stressed the anonymity of students’ identities in the survey. The average time students spent to complete the survey was approximately 15 minutes.<br>

本研究共纳入652名青少年被试，年龄范围为11至20岁，平均年龄（M_age）为14.55岁，标准差（SD）为1.82；其中男生338名，占总样本的51.80%，招募自中国武汉的两所初中与两所高中。所有被试均完成了一系列问卷测评，内容涵盖家庭经济地位（采用家庭富足量表Family Affluence Scale评估）、领悟社会支持（采用领悟社会支持多维度量表Multidimensional Scale of Perceived Social Support评估）、乐观倾向（采用修订版生活取向测验中文版本Chinese version of the Life Orientation Test-Revised评估）以及抑郁症状（采用流调中心用抑郁量表Center for Epidemiologic Studies Depression Scale评估）。本研究的研究方案、问卷及面向学生与家长的知情同意书均提交至本校科研伦理委员会，经专家审核后最终获得伦理委员会批准。获得伦理批准后，研究团队先后拜访合作学校校长，递交问卷与知情同意书副本并请求校方配合。随后，各班班主任通过线上家校沟通系统向家长发送电子知情同意书，说明研究目的、青少年参与的重要性以及参与的自愿性，并请求家长支持与许可。学生将纸质知情同意书带回家，需由监护人签字确认。班主任同时向学生分发纸质知情同意表并动员其参与。仅获得家长同意且自身自愿参与的学生方可纳入本调查。研究人员将成套自陈式问卷以40至50人为一组的形式发放至选定班级的学生手中。经过培训的心理学专业研究生按照统一指导语向学生说明问卷填写要求，并强调本次调查对学生身份的匿名性保障。所有被试完成整套问卷的平均时长约为15分钟。
