Development of a self-report measure of GPS uses and its relationship with environmental knowledge and self-efficacy and pleasure in exploring.

The widely utilized Global Positioning System (GPS) plays a crucial role in everyday navigation. The literature has predominantly focused on GPS use for reaching destinations rather than exploring its various strategic applications and relations with individual factors. The current paper is intended to develop a GPS Uses Scale assessing a variety of GPS uses for wayfinding and other GPS uses (Study 1). We also examine whether GPS uses are related to gender, age, self-efficacy and pleasure in exploring, dependence on GPS devices, and environment knowledge (Study 2). In Study 1, 365 participants completed the new GPS Uses Scale and the McGill GPS questionnaire, for assessing validity. Results from the confirmatory factor analysis confirmed a structure as five-level factors, good reliability, and validity. In Study 2, 200 participants completed the GPS Uses Scale, self-efficacy and pleasure in exploring scale, GPS dependence scale, and a sketch map task after learning a virtual city from a video. Results from the linear model showed that those who use GPS for strategic purposes reported higher self-efficacy and pleasure in exploring as well as dependence on GPS. Moreover, those who use GPS for orientation purposes reported higher dependency on GPS and had higher scores on the map task (environment knowledge). Men were less likely to use GPS for orientation. The present paper outlines the importance of assessing the various uses of GPS, suggesting self-efficacy and dependence on GPS, and contributes to its strategic use.
