Recruitment began 8/7/17. 211 participants across all groups were recruited. Adult, non-student participants were recruited first. Remaining funds will be used to recruit students from PI's home university. Participants were paid $25-$50 for study completion depending on social media condition. More money was given to participants the longer they were off of social media. All participants were randomly assigned to experimental conditions *Final Participant Recruitment Details: All procedures were IRB approved at the authors’ university. The community sample was recruited using a variety of methods. Because one of the inclusion criteria of the present study was being a daily or almost daily user of social media (the other was being 18 years or older), recruitment was conducted through social media. Study researchers joined Facebook groups that reached large, diverse audiences across the United States (e.g., Seattle Garage Sale; What’s Going On In Jones County, NY), and posted the research call a single time on each Facebook group. Additionally, study researchers posted the calls on their own social networks to recruit peers. Fliers were hung locally in the same town as the university sponsoring this research, including in religious organizations, gyms, coffee shops, and street corners. Researchers also mailed fliers to six personal contacts who lived across the US to be hung around similar environments in other cities. To recruit students, a study call was posted online to the research participant pool associated with the department. The present study design took several steps to reduce the demand characteristic during participant recruitment. Specifically, the design attempted to reduce the likelihood the participants could figure out that the study was to measure the effects of abstinence from social media. All materials identified the project as the ‘Time Diary Study.’ The purpose of the study was “to explore how people spend their time each day.” Recruitment information notified potential participants that they may be asked to change their social media habits during the study, but participants were not aware that there were five experimental conditions that varied by time off of social media. Study procedures indicated that all participants who completed the study would receive at least $25 for study completion (for other amounts see below). Student participants earned course extra credit as well as cash. All recruitment material called for interested persons to call or email an address (timediarystudy@) created for the study. Overall, 458 people expressed interest in participating. After contacting the research team primarily by email and seldom by phone, interested participants were randomly assigned to one of seven groups. Initially, the study only included five groups, but during the first week of data collection two additional groups were created to increase sample size. The seven groups differed in the amount of abstinence from social media, which was defined for participants as Facebook, Twitter, Snapchat, and Instagram. The five initial groups (with cash incentives) were as follows: i) control (no change to social media usage) ($25); ii) 7 days social media abstention ($25); iii) 14 days social media abstention ($30); iv) 21 days social media abstention ($40); v) 28 days social media abstention ($50). Groups 6 and 7 represented 7 and 14 days social media abstention, respectively. Participants from those groups were recruited during the first week of data collection, and thus only completed diaries for 21 days of the study. All participants were expected to complete all 28 (or 21) daily diaries regardless of the experimental condition. After being randomly assigned to an experimental group, told the according incentive (e.g., $50 for 28 days of abstinence), and told the time away from social media (when applicable), 89 (19%) individuals declined participation, often stating a need to use social media for work. If a potential participant expressed further interest in the study after the experimental group assignment, he or she was emailed a consent form and a request for contact information, demographic information, and social media account identities on all social media they were active users of (see manipulation check procedures below). If potential participants emailed their demographic and social media information and consented to participate in the study, they were considered enrolled in the study. At this stage of recruitment, 158 contacts (33% of the interested participants) did not respond to an email asking them to affirm or decline participation. At this point, study coordinators made a phone call with every participant to clarify research procedures and/or to answer questions about the consent process. All participants were asked not to talk about the study for its duration. The study began with 211 participants who had consented and who had provided contact and social media account information. After the first week of the study, there was high attrition as measured by non-response to daily diary requests. A second wave of recruitment occurred during the first week of the study through an undergraduate participant pool, adding 21 participants.*
