Considering the fact that emerging adults during the university period present themselves as a group especially vulnerable to cases of anxiety, a study was conducted with the objective of evaluating possible associations between affections experienced by subjects in their family environment and anxious symptoms, based on the theoretical foundation of the Bioecological Model of Human Development. From this perspective, affective aspects relating to the family microsystem of 240 university students between 18 and 25 years of age (MD = 21; AI = 4) were prioritized, with 120 coming from public institutions and 120 coming from private institutions. All subjects were assessed using the Scale of Emotions Experienced in a Family Environment (BEAF), as well as the Generalized Anxiety Disorder scale (GAD-7). Correlational analyzes and tests between contrasting groups were performed. The results indicate significant correlations between the quality of family affection perceived by the participants and the incidence of anxiety symptoms. The higher the score regarding negative affects perceived within the family environment, the higher the total anxiety score reported by the subjects, configuring a positive correlation of moderate magnitude (Spearman correlation =0,472 (level 0,01 two ends); Spearman correlation<0,001). Female participants reported a greater perception of negative affectivity in the family environment, also presenting more symptoms of anxiety. Subjects belonging to socioeconomically disadvantaged families also demonstrated a greater perception of negative affects in the family environment. The findings of this work reaffirm the relationship between affectivity and mental health and alert to the need for greater care with family affective relationships. It is expected that mental health promotion policies will be developed in the future considering the association of such factors, in order to prevent some symptomatic manifestations in this population.
