Rasch Model Analysis of Indonesian Spiritual Well-Being

The existing measurement of spiritual well-being are mostly based on a western perspective.Consequently, its not sufficient to describe the spiritual well-being of easterners, including Indonesia.Considering this fact, this study aims to develop a scale of spiritual well-being based on the perspective of Indonesians.In order to obtain psychometric properties that meet the requirements, validity and reliability tests are conducted based on the Rasch model.Data were collected online through a monkey survey application which contains a scale of Indonesia's spiritual well being containing 35 items.This scale was sent to schools, universities and companies.The collected data (N = 350) were processed to determine the validity and reliability of the scale.The results showed that the scale validity requirements can be met through the unidimensionality test, as well as the infit and outfit score of MNSQ which show that in general the scale of Indonesia's spiritual well being meets the requirements.Based on the item fit test, there were 4 items that must be discarded so that the number of items remaining is 31.Reliability requirements were also met through the Cronbach alpha score, item and person reliability score.However, the Rasch model of the Indonesian Spiritual well being showed that the rating scale still requires further study related to the ambiguity of ratings on this scale
