Application of the Extended Technology Acceptance Model in predicting pharmacists' intention to use personal digital assistants

Objective: To evaluate pharmacists' behavioral intention to use personal digital assistants (PDAs) in their profession, by means of the Extended Technology Acceptance Model (ETAM). Design: Prospective cross-sectional study. Setting: Hospital and community pharmacies in Houston, TX, in 2004. Participants: Convenience sample of 295 practicing pharmacists. Intervention: A prevalidated survey containing 30 items, evaluated on a 5-point Likert scale (1, strongly disagree, to 5, strongly agree), which measured the ETAM variables. Main outcome measures: Predictors of intention to use PDA for pharmacists owning the device. Results: Among the surveyed population, 49% of pharmacists owned PDAs. Overall, the ETAM constructs showed fairly good reliability. Stepwise regression analysis showed that the ETAM explained 69% of the variance in intention to use PDAs for pharmacists owning the device. Result demonstrability (beta = 0.53), subjective norm (beta = 0.25), and voluntariness (beta = -0.10) were significant (P < 0.05) predictors of pharmacists' intention to use PDAs. Conclusion: ETAM proved useful in predicting pharmacists' behavior in using PDAs. With improvements in technology, PDAs be an effective tool for pharmacists in providing better patient care.
