A Videotape to Improve Parental Knowledge of Lead Poisoning
Section snippets
METHODS
This was a prospective clinical trial of the effects of a videotape on parental knowledge of lead poisoning. Parents were recruited from a large ambulatory pediatric clinic at a tertiary care hospital in urban Philadelphia. Parents whose children were 6 months to 6 years of age and were scheduled for well-child visits were eligible for the study. Parents had to be able to read English or Spanish and consent to study participation. Parents could only enroll one time in the study.
Our assessment
RESULTS
There were 510 eligible parents who presented during the study period whose children were between the ages of 6 months and 6 years during the 6-week enrollment period. A convenience sample of 157 parents was approached about participating in the study (31% of eligible parents). Eleven parents refused to participate in the study because they believed that the study would take too long (5), already knew enough about lead poisoning (3), were “too tired,” (1), were not interested (1), or could not
DISCUSSION
The Pennsylvania Department of Health lead poisoning prevention videotape improved parental knowledge, as measured on the sCLKT. We found a statistically significant improvement in test score in the group that watched the lead poisoning prevention videotape (+4.2 of 14 items). These improvements in test score were retained throughout the study period and were associated with an increase in self-reported behaviors, such as hand washing and house cleaning, that may help prevent lead poisoning.
