Reliability and validity of the Roberts UCLA Loneliness Scale (RULS-8) with Dutch-speaking adolescents in Belgium

The internal consistency and construct validity of the RULS-8, a brief measure of loneliness for use with adolescents, was examined in three samples of Dutch-speaking adolescents in Belgium (for a total of N = 6,236). The measure showed high levels of internal consistency (ranging between .80 and .82), strong convergence with the original 20-item instrument (r = .92; Sample 1; N = 282), excellent fit with its hypothesized factor structure through confirmatory factor analysis (Sample 2; N = 1,144), measurement invariance across gender, and significant correlations in the expected direction with...
