To this end, a questionnaire was structured with scales to evaluate family inclusion, loneliness, and perceived stress; the last two scales were previously validated. The sample (n = 347) consisted of young university adults aged 20 to 24 years and their grandparents aged 60 years. The conceptual emphasis of the Family Inclusion Scale generated was the identification of the affective component that facilitates, or does not facilitate, the perception that the focal subject feels positively involved in the family dynamics in which it develops. An Exploratory Factor Analysis was performed to determine the factor structure of the Family Inclusion Scale. This analysis showed that the referred scale consisted of a single factor with eight items. Following this, a preliminary Confirmatory Factor Analysis was conducted to assess the convergent and discriminant validity of the Family Inclusion Scale (FIS). The correlation matrix showed a positive correlation between the FIS and the low-stress perception scale and a negative correlation with the family alienation scale, which was extracted from the loneliness scale. Considering some variation between items, the measurement model showed adequate goodness-of-fit metrics. In conclusion, this work documents the Family Inclusion Scale as an easy and quick questionnaire to apply, which meets robust psychometric properties, supporting its use with samples of Mexican adults.
