Which details about what happened at home would a stress measure leave out?
The study combines student-reported experiences at home with hair hormone measures. Its outcome measures cannot characterize any individual parent-child exchange.
Who was studied?
Two hundred and eighty-two junior high school students in China.
Age / stage: Early adolescence
Read with three questions
- What did the hair sample measure, and what had to be learned from student reports?
- Which parts of the interaction were directly observed and which were inferred or reported?
- Which details about what happened at home would a stress measure leave out?
Keep the limits in view
The study measures behaviors or experiences in a particular sample and setting. It cannot establish the effect of changing a response in an individual family.
