Using photographic interpretation to evaluate the safety of home environments

In the US there were 400,000 home fires resulting in 2755 deaths, 12,450 injuries, and $6.9B lost. The purpose of this study was to evaluate the content-validity of photographs taken in the home for use as an educational instrument to teach about “safe” and “unsafe” fire safety practice for adults and older adults. A total of 73 home fire safety experts were provided 27 photographs to evaluate home fire safety practice. Initially, a Krippendorff's alpha was calculated for the first 24 questions to evaluate inter-rater reliability, and differences in demographics were evaluated. Unique codes and themes for the last three questions were identified and inter-rater reliability examined. A majority of respondents were female (n = 43, 60.6%), college educated (n = 61, 83.6%), nurses (n = 25, 33.8%), or worked for a fire department (n = 21, 29.6%). Their mean age was 45.5 years and they had 11.05 years of experience. The first 24 questions had high inter-rater reliability (Krippendorff α = 0.831). No significant differences existed between the strata of the demographic variables (all p-values > 0.05). Similarly, based on the codes and themes identified, the last three questions had moderate-to-good inter-rater reliability (Krippendorff α = 0.764). Providing photographs as a ‘seek-and-find’ or ‘What's wrong with this picture?’ tools and simplified visual images is an excellent way to aid recognition of unsafe home fire safety environments. Education through non-traditional visual methods increases the possibility of change for diverse low-literacy populations.
