tailieunhanh - Health Information National Trends Survey (HINTS) 2007

The Background section is based on neither a systematic review nor comprehensive literature searches. Some of the Evidence in smaller type may now be out of date. Where possible, information included in the previous Manual based on on-going reviews has been replaced by more recent material. Evidence is graded A (derived from randomised controlled trials - RCTs), B (observational studies) and C (professional consensus). These are broad categories and the quality of evidence within each category varies widely. Thus it should not be assumed that RCT evidence (grade A) is always more reliable than evidence from observational studies (grade B) | Health Information V V Nsl III II 3 Health Information National Trends Survey HINTS 2007 FINAL REPORT Authors David Cantor PhD Kisha Coa MPH Susan Crystal-Mansour PhD Terisa Davis MPH Sarah Dipko MS Richard Sigman MS February 2009 Prepared for National Cancer Institute 6120 Executive Boulevard Bethesda MD 20892-7195 Prepared by Westat 1650 Research Boulevard Rockville MD 20850 Westat Table of Contents Chapter Page 1 Introduction. 1-1 Background. 1-1 Mode of HINTS 2007. 1-1 2 Pretesting Methods and Results. 2-1 Testing of Advance Materials. 2-1 Pilot Studies . 2-2 RDD Pilot Study. 2-3 Mail Pilot Study. 2-5 3 Instrument Development. 3-1 Questionnaire Development. 3-1 Working Groups. 3-1 Question Tracking System . 3-2 CATI Instrument Cognitive Testing. 3-3 Mail Questionnaire Development . 3-3 Mail Cognitive Testing Round 1. 3-4 Mail Cognitive Testing Round 2. 3-5 Mail Cognitive Testing Round 3. 3-5 Final Instruments. 3-6 4 RDD Study Design and Operations. 4-1 Sample Selection. 4-1 Size of RDD Sample. 4-1 Stratification by Mailable Status. 4-2 Subsampling of Screener Refusals. 4-2 HINTS 2007 Final Report i Westat Contents continued Chapter Page Summary of RDD Operations. 4-3 Staffing and Training. 4-3 Advance Materials . 4-4 Calling Protocol. 4-4 Findings From the CATI Operations. 4-6 Weekly Reports. 4-7 Administration Times. 4-8 Average Calls per Case. 4-9 Cooperation Rates and Refusal Conversion. 4-10 Results of Hispanic Surname Coding. 4-11 Data Retrieval. 4-12 Imputation . 4-14 Interview Data Processing. 4-14 5 Mail Study Design and Operations . 5-1 Sample Selection. 5-1 Sampling Frame for Address Sample. 5-1 Selection of Main-Survey Address Sample . 5-3 Mail Survey Operations. 5-4 Questionnaire Mailing Protocol . 5-4 Interactive Voice Response IVR Experiment . 5-5 .
