There is no instrument which collectively assesses the knowledge, attitude and perceived practice of asthma among community pharmacists. Therefore, this study aimed to validate the instrument which measured the knowledge, attitude and perceived practice of asthma among community pharmacists by producing empirical evidence of validity and reliability of the items using Rasch model (Bond & Fox software®) for dichotomous and polytomous data. This baseline study recruited 33 community pharmacists from Penang, Malaysia. The results showed that all PTMEA Corr were in positive values, where an item was able to distinguish between the ability of respondents. Based on the MNSQ infit and outfit range (0.60-1.40), out of 55 items, 2 items from the instrument were suggested to be removed. The findings indicated that the instrument fitted with Rasch measurement model and showed the acceptable reliability values of 0.88 and 0.83 and 0.79 for knowledge, attitude and perceived practice respectively.
目前尚无一种工具能综合评估社区药剂师对哮喘的知识、态度和认知行为。因此，本研究旨在通过使用Rasch模型（Bond & Fox软件®）对二分法和多分类数据的项目有效性和可靠性产生实证证据，来验证测量社区药剂师对哮喘的知识、态度和认知行为的工具。这项基线研究招募了来自马来西亚槟城的33名社区药剂师。结果显示，所有PTMEA相关系数均为正值，即一个项目能够区分受访者的能力。根据MNSQ拟合度和拟合优度范围（0.60 - 1.40），在55个项目中，建议从该工具中删除2个项目。研究结果表明，该工具符合Rasch测量模型，知识、态度和认知行为的可靠性值分别为0.88、0.83和0.79，均可接受。
