Abstract: The Subjective Happiness Scale (SHS) is one of the most commonly used measures of happiness. Many translations and validation studies have been carried out in different countries and languages. The aim of the current paper was to investigate the psychometric properties of the Italian translation of the SHS and to provide normative data. The SHS was administered with life satisfaction items, anxiety and depression scales to a community sample of 993 participants, aged 18–85 years, living in different parts of Italy. Age and gender distributions were stratified according to the population pyramid. Confirmatory Factor Analysis supported the unidimensionality of the SHS, with acceptable fit indexes (NNFI = .96; CFI = .99; RMSEA = .08; 95 % C.I. [.04–.12]). Multi-group analyses supported total invariance of the SHS measurement model for males and females, and partial invariance for younger (i.e., 18–44 years old) and older (i.e., 45–85 years old) participants. Significant correlations with satisfaction items, anxiety and depression provided evidence for concurrent validity. These findings showed that the Italian SHS translation is a reliable and valid tool, which adds to existing translations and validation studies in different countries and languages.
