Parent reports are preferable for secondhand smoke (SHS) exposure due to less underreporting. However, child reports are also valid and collecting both parent and child data improves accuracy.
Area of Science:
- Environmental Health
- Pediatric Health
- Public Health
Background:
- Secondhand smoke (SHS) exposure is a significant health risk for children.
- Accurate assessment of SHS exposure is crucial for intervention effectiveness.
Purpose of the Study:
- To evaluate the validity of children's self-reported secondhand smoke (SHS) exposure.
- To identify factors influencing the accuracy of children's SHS exposure recall.
- To compare child-reported SHS exposure with parent-reported exposure.
Main Methods:
- Utilized a nonprobability sample of 380 families in Southern California.
- Employed timeline followback methodology for retrospective reporting of SHS exposure by parents and children (aged 8-13).
- Validated self-reports against child's urine cotinine levels.
Main Results:
- Child and parent reports showed comparable validity (r=0.53 vs. r=0.58).
- Parents reported significantly more SHS exposure than children (2.2 vs. 0.8 cigarettes/day).
- Combined parent and child reports improved prediction of cotinine levels compared to either report alone.
Conclusions:
- Parent reports are generally preferred due to reduced underreporting of SHS exposure.
- Child-reported SHS exposure demonstrates adequate validity and may be suitable for specific research contexts.
- Collecting both parent and child reports offers complementary data for a more comprehensive assessment of SHS exposure.
