The Impact of Perceived Effectiveness of Non-Pharmaceutical Interventions (NPIs) on Attitude Toward Usage, Behavioral Intentions, and Actual Usage

The purpose is to examine the impact of the perceived effectiveness of NPIs (e.g., hand hygiene, respiratory etiquette, face masks) on behavioral intentions, attitudes toward usage, and actual use against the backdrop of the Technology Acceptance Model (TAM). Responses were gathered with a survey instrument from Canadian respondents ( N = 278). PLS-SEM and exploratory factor analysis (EFA) were used as analytical methods. The hypotheses between the key constructs were accepted consistently with TAM. Also, the results show a positive relationship between perceived effectiveness and attitude toward the usage of NPIs. However, the perceived effectiveness did not significantly impact behavioral intentions and actual use of NPIs. A significant indirect relationship was discovered between perceived effectiveness via attitudes on behavioral intentions and the actual use of NPIs. The perceptions of the respondents who perceived the NPIs to be effective and those who did not were quite similar. The current research provides a framework for effectively promoting the relevant behaviors while utilizing the Technology Acceptance Model (TAM) framework. The critical role of attitude toward the use of NPIs is highlighted through the direct impact of perceived effectiveness and the indirect effect of perceived effectiveness on behavioral intentions and actual usage toward the use of NPIs.
