This study aimed to develop a valid social contact survey instrument and to verify its feasibility for use among Korean adults.
The Delphi technique was used to develop an instrument to assess social contacts, which was then applied in a cross-sectional pilot study. A panel of 15 medical professionals reviewed the feasibility and validity of each item. The minimum content validity ratio was 0.49. Thirty participants used the developed measure to record contacts during a 24-hour period.
After a systematic review, the survey instrument (parts I and II) was developed. Part I assessed social contact patterns over a 24-hour period, and part II assessed perceptions of contacts in daily life and preventive behaviors (hand hygiene and coughing etiquette). High validity and feasibility were found. In the pilot study, the 30 participants had a combined total of 198 contacts (mean, 6.6 daily contacts per person). The participants’ age (p=0.012), occupation (p<0.001), household size (p<0.001), education (p<0.001), personal income (p=0.003), and household income (p<0.001) were significantly associated with the number of contacts. Contacts at home, of long duration, and of daily frequency were relatively likely to be physical. Assortative mixing was observed between individuals in their 20s and 50s. Contact type differed by location, duration, and frequency (p<0.001).
The developed social contact survey instrument demonstrated high validity and feasibility, suggesting that it is viable for implementation.
Korean summary
본 연구에서는 감염접촉전파에 대한 인식과 사회적접촉을 측정 도구를 델파이 방법으로 개발하여 국내최초로 한국 성인의 사회적접촉을 측정하였다. 참여자 30명은 24시간 동안 총 198명을 접촉하였으며(6.6명/일/인), 접촉자수는 연령 (p=0.012), 직업(p<0.001), 가구수 (p<0.001), 교육수준 (p<0.001), 개인소득 (p=0.003), 가구소득 (p<0.001)에 따라 차이가 있었다. 동질성 혼합(assortative mixing)은 20대와 50대에서 보였으며, 접촉유형은 접촉장소, 접촉기간, 접촉빈도에 따라 유의하였다(p<0.001). 향후 국내 사회적 접촉 양상과 특성에 관한 전국적인 후속연구를 제언한다.
