BUZ, José  and  PRIETO ADANEZ, Gerardo. Analysis of the De Jong Gierveld Loneliness Scale Using the Rasch Model. Univ. Psychol. [online]. 2013, vol.12, n.3, pp.971-981. ISSN 1657-9267.

This study examines the psychometric properties of the Spanish adaptation of the De Jong Gierveld Loneliness Scale by means of the Rasch model. Participants were 614 Spanish community-dwelling older adults (60-96 years). Convergent/divergent validity was examined by correlating the scale with both the PANAS scale and a satisfaction with life scale. Results showed that our data fit the model and that average item reliability were high (0.99), but average person reliability was low (0.69). Factorial analysis confirmed a unidimensional structure. Some items had a significant DIF for sex and living arrangements. The scale demonstrated moderate convergent/discriminant validity. These results should be taken into account for a revision of the instrument.
