Note: E = extraversion, N = neuroticism, L = loneliness, L(e) = emotional loneliness, L(s) = social loneliness. Results are based on N_T1 = 346 and N_T2 = 283 observations in Sample 1 and N_T1 = 237 and N_T2 = 129 observations in Sample 2. For reasons of comparability across samples, we transformed all variables of Sample 1 via POMS prior to the analysis. Internal consistencies are provided as Cronbach’s alpha (α). Bivariate correlations in bold font were significant at p < 0.05. Underlined intercorrelations represent retest reliabilities (r_T1,T2).
