Abstract
To assess the psychometric properties of the Dispositional Hope Scale for Chilean children and adolescents (NNA, for its acronym in Spanish). The study was conducted on 331 NNA, aged 10 to 20 years, from different educational centers in the country. Reliability was tested with Cronbach's alpha coefficient. In addition, one-factor vs two-factor models were compared using the Maximum Likelihood (MLR), while validity was analyzed in relation to other variables, specifically depressive symptoms. The scale showed a Cronbach's alpha coefficient of 0.89 and an adequate fit to the two-factor model, keeping the original structure proposed by Snyder et al. It is negatively related to depressive symptomatology. The NNA Hope Scale shows appropriate psychometric properties for its use on Chilean NNA population.
