This study presents a shortened version of the De Jong Gierveld Loneliness Scale, which originally consists of 11 items, to measure overall, emotional, and social loneliness. The 6-item scale was empirically tested on data from two surveys (N = 9,448) using confirmatory factor analysis, which confirmed the specification of two latent factors: emotional and social loneliness. The psychometric properties of the 6-item scale, including reliability and validity, were optimal. The scale demonstrated strong congruence with the original 11-item scale and its subscales, showing high correlations in both test datasets. The shortened scale was also found to be reliable and valid for different age groups, ranging from 18 to 99 years. The study concludes that the 6-item De Jong Gierveld Loneliness Scale is a reliable and valid measurement instrument for overall, emotional, and social loneliness, suitable for large-scale surveys.This study presents a shortened version of the De Jong Gierveld Loneliness Scale, which originally consists of 11 items, to measure overall, emotional, and social loneliness.
