As youth use mobile services for utilitarian and hedonic purposes, their evaluations of mobile service providers may relate to cognitive determinants of service quality, value, and switching costs as well as to affective enjoyment. The findings showed that cognitive determinants related significantly to loyalty, but enjoyment did not. A follow-up investigation suggested that enjoyment moderated relationships between these cognitive determinants and loyalty. Service quality and value related more to loyalty when enjoyment was low, implying that youth who used mobile services for utilitarian purposes were mainly concerned with the services’ quality and value. Conversely, switching costs related more to loyalty when enjoyment was high. Youth who enjoyed common mobile services with peers perceived barriers to switching because using different mobile service providers might distance youth from their peers. This study extends research on hedonic consumption, particularly with Australian youth and mobile services, and offers future research and managerial implications.
