This scale measures how emotionally bonded a person feels to their cell phone, including wanting it nearby and using it often. Song and Sela (2023) used a four-item subset of a slightly longer prior scale to assess this in a study of smartphone use and self-perception.
Likert scale, points not specified in source (a 7-point format is assumed, consistent with other measures in the study)
