Backpacking travel has become a global trend among young people. Despite the importance of personal development among the youth, research has rarely probed the construct of backpackers’ personal development (BPD). The purpose of this study was to develop a scale to measure backpackers’ personal development. The study developed 30 measurement items to construct a survey instrument. The instrument was then administered to collect data from a sample of 397 Chinese backpackers. Following a rigorous process of scale development, a five-dimension (Capability, Emotion, Worldview, Skill, and Self-consciousness) personal development model was identified. A refined scale consisting of 16 measurement items was finally derived meeting both reliability and validity requirements.
