In an online survey, 272 smart phone users reported on their recalled responses to loss\/separation from their mobile phone (not by choice), as well as their use of the mobile phone for self-expansion. Results show that self-expansion via mobile phone was associated with greater inclusion of the mobile phone in the self-concept and greater subjective well-being. Most respondents reported negative feelings, such as loneliness\/disconnection, anxiety, and boredom, when without their mobile phone, but others felt relieved to be out of touch with others. The use of the mobile phone for self-expansion was associated with more negative emotion and less positive emotion (relief) in response to loss\/separation from the phone. Interpretations of the findings are discussed.<\/jats:p>","DOI":"10.1177\/1461444815592665","type":"journal-article","created":{"date-parts":[[2015,7,1]],"date-time":"2015-07-01T22:11:06Z","timestamp":1435788666000},"page":"2452-2468","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":64,"title":["\u201cI miss my mobile phone!\u201d: Self-expansion via mobile phone and responses to phone loss"],"prefix":"10.1177","volume":"18","author":[{"given":"Cynthia A","family":"Hoffner","sequence":"first","affiliation":[{"name":"Georgia State University, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sangmi","family":"Lee","sequence":"additional","affiliation":[{"name":"Georgia State University, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Se Jung","family":"Park","sequence":"additional","affiliation":[{"name":"Georgia State University, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2016,7,9]]},"reference":[{"key":"bibr1-1461444815592665","unstructured":"Anderson TD (2013) Tweens and their in-betweens: giving voice to young people when exploring emerging information practices associated with smart devices.
