Exploring the Association between Attachment Style, Psychological Well-Being, and Relationship Status in Young Adults and Adults-A Cross-Sectional Study.

Background: This study aimed to analyze the associations of adult attachment styles with psychological well-being in relation to age groups (young adults vs adults) and relationship status (singleness vs close relationships). Method : The study sample consisted of 393 Italian young adults and adults, aged 18 to 62 years, with stable close relationships ( n = 219) or identified in this study as singles ( n = 174). The Psychological Well-being Scale was used to analyze psychological well-being, and the Attachment Style Questionnaire was chosen to evaluate adult attachment dimensions. Results: Individuals with stable close relationships reported higher levels of psychological well-being than singles. Furthermore, compared to people with stable close relationships, singles had an attachment style associated with discomfort with closeness, relationships as secondary, and avoidance. Finally, in single people, psychological well-being was moderately and positively predicted by attachment style characterized by confidence but strongly and negatively by attachment characterized by the need for approval. Regarding individuals with stable relationships, psychological well-being was strongly and negatively predicted by attachment style characterized by the need for approval. Conclusions: In adult attachment styles, close relationships can be viewed as a protective factor for long-term emotional stability and psychological well-being.
