Content Validity of Collective Efficacy Questionnaire for Natural Disasters Based on Aceh Local Wisdom

Abstract

Disaster preparedness is one of the efforts to reduce the impact of disasters. This preparedness is very important for people who directly feel the disaster and the impact of the disaster itself. Preparedness behavior in this community can be influenced by collective efficacy, namely the ability of community members to work together and take action in dealing with disasters. For this reason, it is necessary to develop an instrument that can measure collective efficacy in the context of disaster. This research focuses on developing instruments that can measure the collective efficacy of communities in the context of natural disasters based on local wisdom adapted to the local culture of Aceh. Collective efficacy instruments were developed, and content validity was tested. This article describes the procedure for calculating content validity coefficients. The purpose of this study was to conduct content validity of collective efficacy questionnaire for natural disasters based on Aceh local wisdom. Content validity refers to the extent to which the instrument covers the content that is supposed to be measured. Content validity was assessed using a five-point Likert scale and then analyzed using Aiken‟s V formula to obtain the content validity coefficient. Item analysis was carried out by 7 experts in the fields of psychometrics, social science, disaster science, and measurement who assessed content representation based on construction, relevance, and clarity. As a result, of the 47 items that were validated, 7 items did not meet the valid requirements because the content validity coefficient was below 0.75.
