This scale assesses how personal and private a person considers a particular device, and how uncomfortable they would feel with someone else using it. Song and Sela (2023) used it in a pilot study to establish that smartphones are perceived as more intimate than other devices, a distinction central to their broader research on device use and self-perception.
Response format not explicitly stated; possibly not at all (1) to very much so (7)

Reliability varied by device: α = .86 for a smartphone, .79 for a PC, and .86 for a tablet (Song and Sela 2023, Web Appendix A), based on a pilot sample of 100 MTurk participants. The PC administration fell just under the conventional .80 threshold, while the smartphone and tablet administrations both exceeded it. Validity was not separately discussed. Response anchors were not explicitly reported but may resemble the not at all (1) to very much so (7) format used in a related measure.
