Study on the adoption intention of the cognitive impairment screening mini program based on TAM and TPB models

Le résumé fourni par la source

With growing attention to cognitive impairment screening, digital screening tools have become an important approach for early detection and intervention. However, considerable uncertainty remains regarding users' acceptance of such mini programs, particularly among middle-aged and older adults. Based on the Technology Acceptance Model (TAM) and the Theory of Planned Behavior (TPB), this study developed an extended model to investigate the key factors influencing users' intention to adopt a cognitive impairment screening mini program. The extended model incorporated perceived usefulness (PU), perceived ease of use (PEOU), attitude (ATT), trust (TRU), subjective norm (SN), perceived behavioral control (PBC), and perceived privacy risk(PVR), and was empirically tested using structural equation model (SEM). The analysis of 610 valid questionnaires showed that PU was significantly and positively associated with ATT, while PEOU significantly and positively predicted PU. Both TRU and ATT were significantly and positively associated with users' behavioral intention (BI). In addition, SN and PBC had significant indirect effects on BI through ATT and TRU. PVR was significantly and negatively associated with both TRU and ATT, and also had a negative indirect effect on BI. These findings offer practical implications for the design, privacy management, and promotion of digital health tools, particularly the cognitive impairment screening mini programs.
