Smartphone ownership and use continues to proliferate, allowing people to easily access online communication, entertainment, and information. Importantly, individuals can perceive that they overuse their smartphone and/or the social media applications (apps) they access on their devices. Much of the research on smartphone overuse has focused on youth and emerging adults, with little research focusing on individuals in the established adulthood stage of life. This study examines smartphone use among established adults who perceive that they overuse their smartphone and/or social media. As part of a larger study, we conducted in-depth interviews with 21 individuals (30–45 years old) who self-identified as smartphone and/or social media overusers. Data were collected through a pre-survey, 1-hour interview, and smartphone use screenshots. Audio-recorded interviews were transcribed and then coded using NVivo software. Participants’ average age was 35.9 years (SD = 4.1). The majority of the sample were female (67%), White (76%), and had a master’s degree or higher (76%). Participants spent an average of 215 min on their smartphone daily, primarily using social media, video conferencing, and texting apps. Issues with smartphone use occurred when there was an unclear separation between work and personal use. Participants felt pressure to always respond quickly to work emails. An effort was made to limit smartphone use for work and during family time to be present for their family. Established adults strive to balance smartphone use for personal and work purposes. Creating boundaries for how and when established adults use their smartphone may help them find this balance.

智能手机的拥有和使用继续激增，使人们能够轻松访问在线通信、娱乐和信息。重要的是，个人可以感觉到他们过度使用智能手机和/或他们在设备上访问的社交媒体应用程序。大部分关于智能手机过度使用的研究都集中在年轻人和新兴成年人身上，很少有研究关注处于成熟的成年生活阶段的个人。这项研究调查了认为自己过度使用智能手机和/或社交媒体的成熟成年人的智能手机使用情况。作为一项更大规模研究的一部分，我们对 21 名自认为是智能手机和/或社交媒体过度用户的个人（30-45 岁）进行了深入访谈。数据是通过预调查、1 小时访谈和智能手机使用屏幕截图收集的。录音采访被转录，然后使用 NVivo 软件进行编码。参与者的平均年龄为 35.9 岁 (SD = 4.1)。大多数样本是女性 (67%)、白人 (76%)，并且拥有硕士或更高学位 (76%)。参与者平均每天在智能手机上花费 215 分钟，主要使用社交媒体、视频会议和短信应用程序。当工作和个人使用之间的界限不明确时，就会出现智能手机使用问题。参与者感到总是快速回复工作电子邮件的压力。努力限制智能手机在工作和家庭时间的使用，以陪伴家人。成熟的成年人努力平衡智能手机的个人用途和工作用途。为成熟的成年人使用智能手机的方式和时间设定界限可能有助于他们找到这种平衡。
