UNASSIGNED: Marital infidelity is a highly distressing experience for those involved. Understanding the psychological factors related to infidelity can help develop targeted interventions. The primary aim of this study was to assess the association between attachment styles and marital infidelity.
UNASSIGNED: Seventeen studies were included, sourced from electronic databases including PubMed, Scopus, Web of Science, and PsycInfo, with no time limitations, up to April 2023. The search employed terms like \"attachment AND marital infidelity.\" Study quality was evaluated using the Risk of Bias Assessment Tool from RevMan version 5.3.
UNASSIGNED: The meta-analysis involved a total of 13,666 participants, ranging from 208 to 4047 individuals. Findings showed that higher levels of anxiety and avoidance in attachment were significantly associated with increased marital infidelity (r = 0.18, 95 % CI = 0.14-0.22, p < 0.0001). Conversely, weaker attachment insecurity was linked to reduced rates of marital infidelity. Additionally, both dismissive and fearful attachment styles correlated with marital infidelity, with respective weighted effect sizes of r = 0.07, p < 0.001 (95 % CI = 0.04-0.10) and r = 0.19, p < 0.001 (95 % CI = 0.10-0.29). No association was found between preoccupied attachment and infidelity.
UNASSIGNED: Individuals with insecure attachment styles, specifically those with high levels of anxiety or avoidance, are more likely to engage in marital infidelity. Attachment styles should be a focus in couples therapy, especially for treatment related to infidelity. Assessing and addressing these underlying attachment issues can better guide therapists in their work with couples facing infidelity.

According to attachment theory, children\'s early experiences with their primary caregivers, in terms of protection and security, are the basis for socioemotional development and for the establishment of close relationships throughout their lives. During adolescence, friends and peers become a primary developmental environment, and thereby establishing quality bonds with peers will foster good psychological adjustment. The aim of the present study was to review the evidence on the relation of parental attachment to the quality of peer relationships during adolescence. A systematic review was conducted according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search was performed in the PsycInfo, Scopus, and Web of Science (WOS) databases. Inclusion criteria were studies published since 2001, in English, that are academic publications in scientific journals, that explore adolescence, and that analyze the relationship between attachment styles and adolescent peer interactions. The search resulted in 1438 studies, of which 19 studies met the criteria and were included in the review. The results highlighted that secure attachment predicts and promotes the creation of affective relationships with peers and friends based on communication, support, intimacy, trust, and quality. In addition, some variables, such as gender differences or family characteristics, were found to be involved in attachment and provide a better understanding.
