Abstract
Introduction : During the pandemic, like influenza, ebola and MERS, people experience a temporary crisis. Preparing for infectious disease, taking the rapid measure and response system is important. But equally important thing is community reciprocity and trust. Community reciprocity and trust defined as community collective efficacy which is the shared belief in the ability of a group to address problems when it acts conjointly. Collective efficacy strongly influences collective action because it can help determine whether and how the capability of ones group might influence the behaviors of an individual. In community settings, collective efficacy is the belief held by community members is helpful for achieving infectious disease preparedness. So, proper scale and exact measurement in collective efficacy research can add depth in research, also, derives multi-dimensional results. Therefore, development of valid tool reliable in collective level is very necessary and significant. The purpose of this study was to measure group efficacy on infectious disease prevention, verify structural model, and suggest validity and reliability.

Methods : After development of questionnaire, reliability and validity was assessed. In this study, validity confirmed by content validity, construct validity and criterion validity. Also reliability identified by test-retest and Cronbachs α coefficient. A pilot study was conducted with a sample of 250 who live in Seoul and Chung-Nam, Korea.

Result : Test-retest reliability value was 0.71 to 0.95 for the domain of the collective efficacy about infectious disease preparedness. Content validity was assessed by inquiring advice of questionss suitability from the health care experts. After that, verified questionnaire was developed. Following the pilot survey, second validity and reliability assessment was conducted. Construct validity was assessed by exploratory factor analysis and confirmatory factor analysis. The result of exploratory factor analysis showed 5 factors. The validity of the questionnaire was moderately verified by the confirmatory factor analysis (RMR=.41, RMSEA=.59, CFI=.91). Criterion validity was assessed by logistic regression. The association between collective efficacy level and infectious disease knowledge was not statistically significant but the association between collective efficacy level and infectious disease preventive behavior was statistically significant(The collective efficacy level 1, OR : 4.64, CI : 2.03-10.49 The collective efficacy level 2, OR : 3.45, CI : 1.60-7.44 The collective efficacy level 3, OR : 4.70 CI : 1.79-12.31). Lastly, internal consistency was determined with Cronbachs α. The internal consistency reliability ranged from 0.64 to 0.83.

Conclusion : This research could suggest a reliable tool that could measure infectious disease related collective efficacy. The questionnaire developed in this research was secured with reliability and validity, the researcher expects comprehension of collective efficacy level targeting the overall national people could be conducted, based on this, researches on evaluation of public health crisis confrontational ability could be progressed.
