The traditional statistical summation of Likert scale is based on the a priori assumption that all of the items are of equal difficulty and that the thresholds between steps are of equal distance or equal value. The Rasch Rating Scale Model (RSM) emphasize that not only each item have a difficulty estimate, but the rating scale has a series of thresholds to show the progression of the scale used compared to dichotomous data. In order to check the quality of the adapted items based on Malaysian Youth Challenges and also how functions the RSM in calibrating the adversities among youth. The research aimed to investigate the reliability and separation index of adapted items developed and calibrating the main adversities among youth. A set of items in online survey questionnaires with a four-point Likert scale were administered to 500 youth that categorized into early, mid and end youth from five different zones using convenience sampling technique. The data of the questionnaire were analysed using RSM. The items with -0.09 logit from the data set (second quartile or 50 percent), and above are considering as hard to endorse by youth. The findings revealed that all items have good reliability and separation index. The most dominant challenge for all age categories of youth is the economy and the least dominant is technology. The results exposed the potential of logit on the RSM is useful to help organize the adversities. The logit served to convert the ordinal to the interval type of data. The research was contributed to the applications of modern psychometric theory. This information is valuable to redesign the content of the self-development for youth self-development programs, especially to face adversities in their life.
