| Summary: | AbstractDespite the increasing recognition of positive life skills interventions to enhance the psychological and physical well=being of individuals, there is an absence of a valid and reliable Arabic measure of Life Skills (LS) amongst youth. This study aims at validating an Arabic Life Skills Scale (A-LSS) to assess the effectiveness of life skills interventions. A randomly selected sample of 1200 university students in Lebanon participated in this study. The exploratory-to-confirmatory factor analyses strategy was followed to examine the factor structure of the LSS. For that purpose, the sample was divided into two subsamples. The exploratory factor analysis results showed a nine-factor solution, with a strong reliability for the total scale (McDonald’s omega ω = 0.95) and all subscales (ω ranging from .68 to .91). The confirmatory analysis results showed excellent fit indices (CFI = .98, TLI = .97, GFI = .95; RMSEA = .031 [90% CI .028–.034] and SRMR = .061), after correlating residuals of items 53 and 54. Measurement invariance across genders was verified at the configural, scalar and metric levels. The A-LSS showed high reliability and validity of LS among Lebanese university students. This scale can be used as a valid tool to measure effectiveness of life skills health promotion interventions.
