The Relationship of Frailty with Psychopathology, Childhood Traumas and Insecure Attachment in Young Adults: A Cross-Sectional Investigation.

Objective: Reciprocal connections exist between mental health and physical health, and conditions of cellular senescence/advanced biological age have been observed in association with certain psychiatric diseases. However, the construct of frailty has only preliminarily been explored in young adults and in relation to psychopathology so far. In the present study we aimed at further elucidating the relationships linking psychopathological phenomena with physical diseases in a sample of young adults.

Methods: The sample was made of 527 Italian young adults (age range: 18-34). Participants were assessed on clinical/socio-demographic information as well as on the following measures: an ad hoc designed Frailty Index (FI), the Brief Symptroms Inventory (BSI), the Relationship Questionnaire (RQ), and the Childhood Trauma Questionnaire (CTQ).

Results: Individuals with clinically-relevant psychopathological symptoms (based on established BSI cut-off scores) showed significantly higher FI values than individuals without clinically-relevant psychopathological symptoms (p<0.001). Higher levels of childhood traumatic experiences and higher levels of insecure forms of attachment were significantly associated with higher FI scores. The severity of preoccupied attachment style was significantly independently associated with higher FI scores also when multiple confounding variables were controlled for.

Discussion: Our findings provide novel pieces of insight on the complex relationship of frailty, conceptualized as a measure of deficit accumulation and an indicator of functional status and biological age, with psychopathology, childhood traumas and insecure attachment, with potential implications for the clinical management of young individuals.
