Development of knowledge test to measure the knowledge level of farmers on scientific pig farming practices

The present study was undertaken to develop and standardize a reliable and valid knowledge test to assess the knowledge level of pig farmers regarding scientific pig farming practices in Kerala. A total of 97 knowledge items were initially prepared and then subjected to expert evaluation for relevancy rating and 55 items were selected for item analysis. The analysis was conducted with 30 non-sample pig farmers across five districts of Kerala. Items that had a difficulty index (25 to 75 per cent), discrimination index (0.30 to 0.70) and point bi-serial correlation values significant at the 5 per cent level were selected for the final knowledge test. Out of 55 items, 18 items were finally selected. The reliability of the test was established using Cronbach’s alpha coefficient, which was 0.826, indicating a good level of internal consistency. This test can be effectively used to measure the existing knowledge level of pig farmers and identify knowledge gaps. It will be highly useful for extension functionaries, policymakers and administrators in formulating skill oriented and need-based training programmes as well as implementing effective extension strategies for improving the livelihoods of farmers.
