Validation of the knowledge, attitude and perceived practice of asthma instrument among community pharmacists using Rasch analysis

Abstract

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.

Validation and Reliability of Healthcare Workers’ Knowledge, Attitude, and Practice Instrument for Uncomplicated Malaria by Rasch Measurement Model

“…It is a model for the design and evaluation of relationships between the latent trait of interest, and the observed variables (items) in addition to determine how the test instrument as a whole relates to the latent trait (Wirth and Edwards, 2007;Thompson, 2009). The use of Rasch method has been considered a better option for such analysis since it takes both persons and items' attributes into account, and it is also convenient for this kind of studies (Rasch, 1980;Zamalia et al, 2013;Janssen et al, 2014;Akram et al, 2015;Müller et al, 2015). The patterns of individuals' responses to items (consistent or idiosyncratic) are indicated by person fit index value.…”

Knowledge, Attitudes and Perceived Practice Towards Asthma Among Pharmacy Students in Southern Nigeria

“…Few published studies have explored pharmacists' perceived roles in asthma management and counselling. Research in this area has primarily focused on structured community pharmacy based asthma programmes [15,16]. Overall, less than half of the students had good perception of the roles of pharmacists in counselling asthma patients.…”

“…Patient counselling requires the pharmacist to allot sufficient time, accordingly. Factors such as large numbers of patients per pharmacist or the patient's eagerness for fast discharge constitute the major challenges that pharmacists face [15].…”

“…Also, pharmacists should avoid the use of medical jargons but as much as possible strive to be understood by the patient [17]. Most of the students agreed that financial incentives have a low impact on the ability of pharmacist to provide specific asthma counselling or services since pharmacist's consultation fee is not common in this part of the world [15]. The respondents believed that patients' perception that they are already well taken care of by the doctor has a considerable to high impact on the ability of pharmacists to provide specific asthma counselling.…”

Validation of Malaysian Versions of Perceived Diabetes Self-Management Scale (PDSMS), Medication Understanding and Use Self- Efficacy Scale (MUSE) and 8-Morisky Medication Adherence Scale (MMAS-8) Using Partial Credit Rasch Model

“…The Rasch-Model has been increasingly used in health field and explores the performance of each item [19]. In general, to develop or translate an instrument, we should examine if a set of items in the instrument measure the target construct consistently (validity and reliability).…”
