Abstract
Research about subjective well-being has had an increase during the last decades. Therefore, it is of great interest to have validated measurement instruments in the contexts of use, in order to increase the quality of this. The most used instrument to measure life satisfaction is the “Satisfaction with Life Scale” (SWLS). Thus, the purpose of the present study has been to analyze the psychometric properties of this scale for its use in Angolan young adults. 1,332 people formed the sample, with ages varying from 18 to 30 years, coming from different northern, center and southern Angolan localities. The factorial validation analyzes confirm that the five (5) items that make up the scale conform a unifactorial structure. Internal consistency indexes, as well as nomological validity, again indicate that SWLS is a valid and reliable scale for assessing satisfaction with life. Finally, the item response theory analyzes provide valuable information on the reliability of the measure and on the highly discriminatory nature of the items that compose it. Finally, the theory analysis of the item response provide valuable information on the reliability of the measure and on the discriminatory nature of the items that compose it.
