Video technology. Use in nursing research

Video technology is becoming more popular as a research tool because it has unique features that capture accurately and comprehensively the nature of nursing phenomena. Video technology is used extensively in nursing as an educational tool or intervention, a means of monitoring quality assurance standards, and as tool to collect research data. Videotaping is useful because is provides continuous multi-media, multisensory information about the subject and its context. Credibility for video data is based on the question of to what extent do the data or results adequately represent true behavior. The three main issues in video research that impact the credibility of data are observer bias, participant reactivity to knowledge of being videotaped, and maintenance of consistent data quality. Not all threats to credibility can be overcome. The key is to acknowledge insurmountable problems, to consider their limitations in data analysis, and to evaluate and report their effects.
