Design and reliability of pediatric HealthQuiz: preliminary report of a comprehensive, computerized, self-administered child health assessment.
The time available for pediatric ambulatory visits is rarely sufficient to permit a truly comprehensive health assessment. We hypothesized that a reliable, computerized, self-administered questionnaire could be designed to screen for a full range of pediatric health issues and provide a comprehensive health database for pediatric patients. An age- and gender-specific pediatric questionnaire of 478 questions was formatted to elicit only a "Yes," "No," or "Not Sure" response and structured in a branched, decision-tree format. The initial draft was reviewed for content by pediatric experts in Canada and the United States and revised in accordance with their suggestions. The questionnaire was divided into two modules, Medical Peds, covering biomedical issues and Prevent Peds, covering prevention, psychosocial, educational, and safety topics. Cognitive interviews were carried out with 132 parents in pediatric ambulatory care centers in Chicago and Halifax, with use of scripted and nonscripted probe questions, to ensure comprehensibility among patients with widely varying educational levels and health knowledge. Reliability was tested in 100 parents of children aged 1 month to 12 years, through use of five different test-retest sequences. Respondents' impressions were surveyed on completion of the procedure. Following content reviews, and cognitive and reliability testing, the total bank of questions was reduced to 375. As a result of the use of branching logic, individual parents answered an average of 111 Prevent Peds and 144 Medical Peds questions. Average time required to complete the entire questionnaire was 13 minutes for Prevent Peds and 19 minutes for Med Peds. Retesting within 36 hours showed an overall 97% concordance of response pairs in the Medical Peds and Prevent Peds questionnaires. There were no statistically significant differences in test-retest reliability between different sequence formats used, (e.g., HealthQuiz followed by personal interview, or HealthQuiz vs. HealthQuiz). A few questions that frequently elicited "Not Sure" responses were eliminated. As a result, the majority of questions elicited either a "Yes" or "No" response. Pediatric HealthQuiz identified a wide spectrum of child health problems that are often overlooked in routine health visits. Parents completing Pediatric HealthQuiz indicated a high degree of satisfaction with the procedure. Most reported that they believed the information would improve their child's health care.
