Development of knowledge test to measure the knowledge level of farmers on interventions of the NICRA project for climate change adaptation

Abstract

The study focused on climate change adaptation under the Technology Demonstration Component (TDC) of the NICRA project and attempted to construct a knowledge test to measure the knowledge level of farmers. Items about climate-smart interventions under the NICRA project were collected from relevant literature and through consultation with scientists. The study was conducted in the Kathua district of Jammu region for item analysis. Item analysis provided a difficulty index and item discrimination index. One mark for each correct and zero mark for each wrong answer was assigned. Finally, the reliability of the test using split half method was found to be highly reliable. Content validly was assessed by CVR (Content validity Ratio), CVI (Content Validity Index), and Kappa statistic. The item content validity index (I-CVI) ranged from 0.63 to 1.0, the I-CVI value above 0.78 was considered fit for the instrument. The instrument was assessed with high content validity. A total of 18 statements were finally retained which contains 4 multiple choice response, 3 alternate response, 3 identifications from photographs, and 8 open response items.
