RIBEIRO, Maria Gabriela Costa et al. Disposition to Nostalgia Scale: Development and Psychometric Evidence. Aval. psicol. [online]. 2021, vol.20, n.1, pp. 1-10. ISSN 1677-0471.  http://dx.doi.org/10.15689/ap.2021.2001.15974.01.

This study aimed to develop the Disposition to Nostalgia Scale (DNS) and to investigate evidence for its factorial validity, convergent validity and internal consistency. The aim was to assemble 20 items that were in the literature or were designed with the purpose of describing nostalgic experiences. Participants were 208 undergraduate students (M_age = 22.8 years, SD = 6.13, ranging from 18 to 60), the majority male (50.7%), single (86.5%), and from the middle social class (54.1%). They answered the initial items of the DNS and two other measures that assess the same construct: The Nostalgia Inventory (NI) and the Southampton Nostalgia Scale (SNS), in addition to demographic questions. Factorial analysis (PAF) was performed, identifying a general factor that accounted for 42.3% of the total variance, presenting adequate reliability (α = .84). Corroborating evidence for its convergent validity, the DNS scores correlated positively with the two other nostalgia measures (NI and SNS). In conclusion, the DNS presents adequate psychometric properties and can be used to assess the disposition to nostalgia.
