Problematic smartphone usage, associated with impaired daily functioning, has gained increased attention among researchers. However, extant research is focusing on adolescents and younger adults. This paper investigates smartphone usage among older adults, of which less is known. To do so, we conducted a cross-sectional survey of 154 smartphone users (60+ years) in Norway using structural equation modeling (PLS-SEM). We examined the contributing roles of loneliness, habit, social influence, emotional gain, fear of missing out, self-control, and problematic smartphone usage. We further investigated how older adults engage with their smartphones. Our findings suggest that older adults use smartphones for various social and non-social reasons and that social media and news reading are the most common use areas. Furthermore, we found a low prevalence of problematic smartphone usage among older adults. Whereas social influence and habit were strong predictors of smartphone usage among older adults, loneliness was not. Fear of missing out was not prevalent among older adults. As we expected, higher self-control was associated with lower problematic smartphone use. Finally, we discuss the contributions and implications of our findings.

与日常功能受损相关的智能手机使用问题，已引起研究人员的越来越多的关注。但是，现有的研究集中在青少年和年轻成年人上。本文调查了老年人中智能手机的使用情况，但鲜为人知。为此，我们使用结构方程模型（PLS-SEM）对挪威的154个智能手机用户（60岁以上）进行了横断面调查。我们研究了孤独感，习惯，社会影响力，情感收获，害怕失踪，自我控制和有问题的智能手机使用等方面的重要作用。我们进一步调查了老年人如何与智能手机互动。我们的研究结果表明，老年人出于各种社交和非社交原因使用智能手机，并且社交媒体和新闻阅读是最常见的使用领域。此外，我们发现老年人中有问题的智能手机使用率较低。社会影响力和习惯是老年人使用智能手机的重要指标，而孤独感却并非如此。对失踪的恐惧在老年人中并不普遍。正如我们预期的那样，较高的自我控制与较低的智能手机使用率相关联。最后，我们讨论了我们的发现的贡献和启示。
