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

Participants were 652 adolescents (age range:
11-20 years old, Mage
=14.55 years, SD = 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.
