Notes. a1, a2, a3 = regression coefficients of social media use predicting state existential isolation, emotional loneliness, and social loneliness, respectively. b1, b2, b3 = regression coefficients of state existential isolation, emotional loneliness, and social loneliness predicting meaning in life, respectively. C1 = state existential isolation minus emotional loneliness (a1b1a2b2); C2 = state existential isolation minus social loneliness (a1b1a3b3); C3 = emotional loneliness minus social loneliness (a2b2a3b3).

Boot LLCI = bootstrapping lower limit confidence interval; Boot ULCI = bootstrapping upper limit confidence interval; SE = standard error; C# = contrast.
