Development of the Mobile Phone Attachment Scale.

Existing instruments that assess the individual's relationship with technology tend to focus on negative constructs and assume that a high use of technology reflects pathology. Since technology use can be beneficial, there is a need for a more balanced instrument. An initial survey to assess the individual's relationship with their mobile phone was developed, checked for face validity and the resulting survey was administered online to students at local colleges. 146 adults (mean age=25.5 years) completed surveys. Principal Component Analysis with varimax rotation produced a final 27-item scale with factor loadings from .50 to .81, representing 4 components: "Usefulness", "Anxious Attachment", "Addiction" and "24/7" (continuous use). This study produced an instrument to assess multiple aspects of the individuals' relationship to their mobile phone. Additional work is needed to validate this measure in other populations, with larger samples, and to assess its predictive ability in mHealth interventions delivered through mobile phones.
