Profiles of intolerance of uncertainty, separation anxiety, and negative affectivity in emerging adulthood: A person-centered approach

Background: Although Intolerance of uncertainty (IU), separation anxiety, and negative affectivity seem theoretically interrelated, no empirical study has considered them jointly so far. However, deepening this topic is clinically relevant, especially during the delicate phase of emerging adulthood. This study aimed to pinpoint psychological profiles based on IU, separation anxiety symptoms, and negative affectivity in a group of Italian non-clinical emerging adults. Such profiles were then compared in terms of key psychological and psychosocial characteristics.Methods: 868 young adults (73 % women) aged 18-26 years entered the study. They completed a sociodemographic survey and self-report tools assessing IU, separation anxiety symptomatology, and personality traits. Subgroups exhibiting distinctive patterns of IU, separation anxiety symptoms, and negative affectivity were identified using latent profile analysis. To deepen disparities in psychological and psychosocial features by profile, analyses of variance and chi-square tests were performed.Results: Three profiles were detected, respectively with high, low, and moderate levels of the variables considered. In each profile, IU, separation anxiety symptoms, and negative affectivity had a consistent trend. The High-level profile had the greatest proportion of women and people who had not spent infancy with both parents. Limitations: The sample included mainly women and university students, and data were collected using self report questionnaires only.Conclusions: IU, separation anxiety symptoms, and negative affectivity can co-occur, highlighting the importance of transdiagnostic interventions. Preventive efforts should be directed to emerging adult women and those who did not spend infancy with both parents, as they may be particularly vulnerable to internalizing distress.
