The present study addresses these limitations by investigating how insecure attachment to mothers, fathers, and peers is associated with psychological distress in early adolescence (grades 7\u20139), with particular attention to the mediating role of loneliness. This developmental period represents a critical window for intervention, as patterns of social\u2013emotional adjustment established during early adolescence often persist into adulthood. Our sample comprised 813 junior high school students who completed 3 well-validated self-report measures: the Relationships Structures Questionnaire assessing attachment patterns; the University of California, Los Angeles Loneliness Scale measuring subjective social isolation; and the Depression Anxiety Stress Scales-21 evaluating psychological distress. Using structural equation modeling, we tested three mediation models to examine both direct and indirect pathways from insecure attachment to psychological distress through loneliness. The results revealed several important patterns: First, we observed moderate positive correlations between anxious and avoidant attachment styles (\n                    <jats:italic>r<\/jats:italic>\n                    = .38\u2013.44), suggesting that these insecure attachment patterns frequently co-occur. Second, structural models demonstrated significant total effects of insecure attachment on psychological distress across most relationship figures, with the notable exception of avoidant peer attachment. Third, while both anxious and avoidant attachment positively predicted psychological distress, avoidant peer attachment exhibited a negative association with distress symptoms. Fourth, and most crucially, loneliness emerged as a significant mediator in all models, explaining substantial portions of the attachment\u2013distress relationship. Gender, attachment style, and loneliness together explained 36%\u201338% of the variance in distress. These findings have important theoretical and practical implications. Theoretically, they extend attachment research beyond its traditional focus on parental relationships by demonstrating the unique and combined influences of multiple attachment figures during early adolescence. Practically, the robust mediating role of loneliness suggests that interventions targeting both attachment security and social connection may be particularly effective for reducing adolescent distress. We recommend that family education programs incorporate attachment-informed parenting strategies while school counseling interventions address peer relationships and loneliness directly.\n                  <\/jats:p>","DOI":"10.1891\/jcp-2025-0001","type":"journal-article","created":{"date-parts":[[2025,6,25]],"date-time":"2025-06-25T18:40:16Z","timestamp":1750876816000},"page":"7-23","source":"Crossref","is-referenced-by-count":2,"title":["Insecure Attachment and Psychological Distress in Early Adolescence: Loneliness as a Mediator"],"prefix":"10.1891","volume":"40","author":[{"given":"Chih-Ling","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pei-Chen","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"793","published-online":{"date-parts":[[2025,6,25]]},"reference":[{"key":"2026022514450979000_40.1.7.1","doi-asserted-by":"publisher","DOI":"10.1016\/S0065-3454(08)60032-7"},{"key":"2026022514450979000_40.1.7.2","doi-asserted-by":"publisher","DOI":"10.1037\/0003-066X.44.4.709"},{"key":"2026022514450979000_40.1.7.3","doi-asserted-by":"crossref","unstructured":"Ainsworth, M.
