Fiability and construct validity of MUNSH test to measure happiness, in older Chilean population

The goal was to adapt and to conduct the preliminary validation of the Scale of Happiness of the Memorial University of Newfounland (MUNSH). Three hundred elderly of more than 65 years answered the MUNSH, the Life Satisfaction Scale of Diener (ESV), and the Abbreviated Geriatric Depression Scale of Yesavage (EGADY). The MUNSH reached a Cronbach's alpha consistency of 0.90, and correlated positively with the ESV (r = 0.623) and negatively with the EGADY (r = -0.746), demonstrating appropriate convergent validity. A factor analysis revealed a multifactorial structure for the MUNSH with a single factor explaining 35% of the variance. The data collected with the MUNSH are analyzed in terms of age and sex differences and separate normative scores are provided
