Determine the indicator's value by using the methodology summarized below. If you need more detailed guidance or practical examples on any of the following points, you can find it in WFP’s manual on using CSI (see at the bottom of this site).
1) Identify the most frequent coping strategies that local people use when they do not have enough food and do not have enough money to buy food. While you can take advantage of a list of the most common strategies included in WFP's guidance (see below) or those identified by the national Food Security Cluster (if available), you will need to adjust the list to make it more context-specific, so that only strategies that are used locally during food insecure times are included in the assessment. There is no point in asking people about strategies they do not use or strategies that are common even in food secure periods, such as collecting wild food in the river.
2) Identify how "severe" each of these individual coping strategies is considered to be. Such information needs to be collected from community-level focus group discussions, providing a "weight" for the perceived severity of each strategy (1 - low, 2 - medium, 3 - severe).
3) Conduct individual interviews with a representative sample of the target group members to assess how frequently people had to use these strategies in the assessed recall period (e.g. twice in the past 7 days). During the interview, the data collectors ask the following question about each of the selected coping strategies: “In the past 7 days, if there have been times when you did not have enough food or money to buy food, how often has your household had to [specify the coping strategy]”.
4) During the data analysis, for each coping strategy, multiply the assigned "weight" with its frequency, receiving the "score" per each strategy. For example, if a coping strategy with a weight of “2” was used three times in the past 7 days, the score of this strategy is 6 (2 x 3 = 6). Read in more detail about calculating the scores in WFP’s guidance attached below.
5) By adding up the scores of all assessed strategies you will receive the total Coping Strategy Index score of the surveyed household. A high score means an extensive use of negative coping strategies and hence increased food insecurity.
6) The scores are usually divided into three categories: low CSI score (0-50), medium (51-100) and high (over 100). However, these thresholds often need to be modified based on the context and the number of coping strategies you assess (e.g. to 0-40; 41-80; and over 80). Once you set the thresholds, count the number of households with a score in the highest CSI category.
7) To determinate the indicator’s value, divide the number of households in the highest CSI category by the total number of surveyed households. Multiply the result by 100 to convert it to a percentage.
