Excessive social media use can be problematic, with risks for individuals including compromised health and wellbeing and disruptions to work and personal relationships. Currently there is a lack of empirically supported treatments for reducing problematic social media use. Stinson and Dallery (2023) recently demonstrated the success of a behavioural intervention in reducing social media use with nine university students in Florida. I aimed to conduct an approximate replication of their intervention with university students in New Zealand. I initially administered a modified Internet Addiction Test to 148 participants. Of these, 38 qualified and three completed the behavioural intervention study. Social media use was tracked through the screen time function of each participant’s smartphone. Once a stable baseline was established, participants began an intervention phase. The intervention was contingency management with automated notifications and the selection of three alternative activities. Results of this intervention indicate success in the reduction of social media use for two of three participants. However, a lack of evidence to suggest any increase in the duration of time spent in chosen alternative activities replaced social media use. These results raise further questions regarding the effects of environmental changes on the strength of contingency management reinforcement for participants during this intervention. Identifying key variables in the reinforcement of contingency management that successfully reduces social media use for participants could be beneficial to many groups, particularly students who may use social media to escape academic demands.
