National Health Interview Survey • Face-to-face household survey • Nationally representative sample of civilian, non-institutionalized US population • Sample yields data on approx. 100,000 persons per year
Timeline • 1957-96 Imbedded in questionnaire • 1997-99 Section on injury & poisoning • 2000-03 Combined inj & poi questions • 2004 “Unpacked” screen question
Changes from the 1995 Survey to the 1997 Survey • Placement, phrasing and number of questions • Recall period • Severity threshold
Data issues: 1997-1999 • Some questions not common to both injuries and poisonings • Injuries recorded as poisonings and poisonings recorded as injuries • High proportion in Other • No question on treatment location
Changes: 1997-99 to 2000 Survey • Combined injury and poisoning questions • Added a question about medical advice or treatment • Revised categories for several questions
Screener question:1997-99 and 2000-present 1997-99: DURING THE PAST THREE MONTHS, that is since {91 days before today date}, {were/was} {you/anyone in the family} injured seriously enough that {you/they} got medical advice or treatment? DURING THE PAST THREE … poisoned seriously enough that you …? 2000: DURING THE PAST THREE MONTHS, that is since {91 days before today date}, {were/was} {you/anyone in the family} injured or poisoned seriously enough that {you/they} got medical advice or treatment?
Fixed Question Wording 1997-99: How many different times in the PAST 3 MONTHS {were/was} {you/subject’s name} injured seriously enough to seek medical advice or treatment? 2000: How many different times in the PAST 3 MONTHS did {you/subject’s name} seek medical advice because {you/subject’s name} were injured or poisoned?
Finding Solutions to the Other Problems • Analyzed data • Held a teleconference with the interviewers in the field • Sent the injury and poisoning section through the Questionnaire Design Research Lab
Unpacking the question 2000-03: DURING THE PAST THREE MONTHS, that is since {91 days before today date}, {were/was} {you/anyone in the family} injured or poisonedseriously enough that {you/they} got medical advice or treatment? • Three questions in one: • Were you injured? • Were you poisoned? • Did you seek medical advice?
