^aThe usage time per day for social media was converted to a monthly rate as follows: Do not use was 0 h; 0–2 h was 30 h, 2–4 h was 90 h, 4-6 h was 150 h, 6–8 h was 210 h, 8–10 h was 270 h, 10–12 h was 330 h, and 12 h or more was 360 h

^bThe “number” of topics is a count of the dummy variable of 11 types of common posting content (including “others”). This was determined using a series of yes-or-no questions, counting “yes” as “1” and “no” as “0”

^cFor calculating the frequency of participants’ social media posts, we considered the following responses and their respective scores: never or seldom = 0 day/month; once per month = 1 day/month; once a week = 5 days/month; several times a week = 15 days/month; and almost every day = 30 days/month
