A pilot study to validate measures of the theory of reasoned action for organ donation behavior

Abstract

The present study aimed at taking the first attempt in validating the measures generated based on the theory of reasoned action (TRA). A total of 211 university students participated in the study, 95 were included in the exploratory factor analysis and 116 were included in the confirmatory factor analysis. The TRA measurements were established with adequate psychometric properties, internal consistency, and construct validity. Findings also suggested that attitude toward organ donation has both a cognitive and affective nature, while the subjective norm of the family seems to be important to students' views on organ donation.

COVID-19 anxiety scale (CAS): Development and psychometric properties

“…That is, the average of the participants should be equal to 3.0, with a standard deviation of 0.0. Otherwise, the item would be considered partially inappropriate (Wong & Chow, 2017).…”

A Validation Study of the Posthumous Organ Donation Reasoned Action Scale

“…Considering the perception items of organ donation were built upon the behavioral outcomes that were the foundation blocks of attitude according to the theory of reasoned action, hierarchical multiple regression analysis was also performed on the direct measure of attitude generated under the theory (Wong & Chow, 2018), with the perception dimensions entered into the model. There was no multicollinearity among the variables.…”

“…One note worth mentioning is that in completing the questionnaire, the participants were asked to think about their organ donation upon death in the present study that such instruction was seldom explicitly stated in the past research (Wong & Chow, 2018). Such expression is highly recommended that could stimulate the participants to answer the items in a deeper and more authentic manner with their imagery and feelings triggered, thereby enhancing the accuracy of the study.…”

“…Two hundred and twenty-one undergraduate or postgraduate students in Hong Kong participated (aged from 18 to 45 years). Data were collected during which the same students participated in a recent study (Wong & Chow, 2018). They were recruited in class, through invitation email messages within the network of the University of Hong Kong, or further forwarded by the recipients of the message.…”

“…From the exploratory study, 37 perception items were identified, with items such as ''posthumous organ donation can give hope to those waiting for an organ transplant'' and ''I feel that donating organs after death is inauspicious''. Among which, 17 items were behavioral outcomes that were examined and established as an indirect measure of attitude in a previous study (Wong & Chow, 2018). In that study, each behavioral outcome was measured by multiplying the corresponding beliefs strength and the outcome evaluation according to the theory of reasoned action, and the overall score was obtained by summing all the multiplicative terms.…”
