Text me when it becomes dangerous: Exploring the determinants of college students’ adoption of mobile-based text alerts short message service

Guided by Davis’ (1986) technology acceptance model (TAM) and Brehm’s (1989) reactance theory, this study sought to explore the determinants of college students’ adoption of mobile-based text alert short message service (SMS). The findings of the study supported the primary argument of the model that individuals’ adoption of text alert SMS for emergency preparedness and response should be largely determined by social psychological factors, such as attitude toward, subjective norm associated with, and perceived intrusiveness of the SMS. In addition, the findings demonstrated that subjective norm of and attitude toward the service prompted individuals’ actual adoption whereas intrusiveness of the service served as a distinctive barrier to the actual adoption behavior. Finally, the findings also showed that the probability of adopting the text alert SMS was not directly increased by perceived ease of use and perceived usefulness of the service, but was indirectly affected by the two antecedents through ones’ attitude toward the use of the SMS. Theoretical and practical implications of the findings are discussed.

• We explore the determinants of adoption of mobile-based text alert service.
• Subjective norm of and attitude toward the text service promote the adoption.
• Perceived intrusiveness served as a distinctive barrier to the adoption.
• Perceived ease of use and perceived usefulness indirectly influenced the adoption.
