[Purpose/significance] Investigating the elements and mechanisms of digital detox behavior of mobile so⁃cial media users can help to enrich the information behavior model, provide theoretical and applied guidance for the indepth analysis of the digital detox behavior of mobile social media users, and ensure a healthy balance between the us⁃ers' normal life and the time they spend on digital devices. [Method/process] Based on the CAPS theoretical model framework, we analyze the elements of the digital detox behavior of mobile social media users from the four dimensions of "context-cognitive-emotional-behavioral", and we use the key event technology method to deeply excavate the in⁃trinsic mechanism of the behavior, and construct the mechanism-relationship model of the digital detox behavior of mo⁃bile social media users. model. [Result/conclusion] The mechanism of digital detox behavior of mobile social media us⁃
ers can be divided into four sub-mechanisms: situation-driven, cognitive connection, emotional regulation and behav⁃ioral response. The management strategies for digital detox behavior of mobile social media users include four aspects:seeking alternative activities and building real-life scenarios; taking the initiative instead of being passive and enhanc⁃ing self-awareness; establishing incentive mechanisms and strengthening positive emotions; using device functions torestrain behavioral habits.
