ABSTRACT: Introduction: Adult attachment is theorized to affect psychological adaptation to bereavement. Attachment anxiety and attachment avoidance relate positively to grief levels concurrently. Yet, controlled longitudinal studies do not find that these attachment dimensions predict changes in grief levels. Therefore, we aimed to test the hypotheses that stronger lingering attachment to the deceased and lower use of living others to fulfill attachment-related needs longitudinally predict increased grief levels. Methods: A sample of 356 bereaved adults (84% women) completed a baseline survey assessing sociodemographic and loss-related characteristics, attachment anxiety, attachment avoidance, lingering attachment, use of living others for attachment needs, and grief levels. Additionally, 188 participants completed a measure of grief levels at 2-month follow-up. Results: Zero-order correlation analyses showed that stronger attachment anxiety, attachment avoidance, and lingering attachment related to higher grief levels concurrently and longitudinally, whereas the use of living others for attachment needs only related negatively to grief levels concurrently. Multiple regression analyses demonstrated that attachment anxiety and lingering attachment predicted higher future grief levels, over and above baseline grief levels. Discussion: Findings support a role of attachment anxiety and lingering attachment in adaptation to loss. Developing therapeutic techniques to reduce lingering attachment to the deceased might improve grief therapies."},"dsDescriptionDate":{"typeName":"dsDescriptionDate","multiple":false,"typeClass":"primitive","value":"2025"}}]},{"typeName":"subject","multiple":true,"typeClass":"controlledVocabulary","value":["Social Sciences"]},{"typeName":"keyword","multiple":true,"typeClass":"compound","value":[{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Attachment style"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Attachment hierarchy"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Lingering attachment"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Grief"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Bereavement"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"Prolonged grief disorder"}}]},{"typeName":"publication","multiple":true,"typeClass":"compound","value":[{"publicationRelationType":{"typeName":"publicationRelationType","multiple":false,"typeClass":"controlledVocabulary","value":"IsCitedBy"},"publicationCitation":{"typeName":"publicationCitation","multiple":false,"typeClass":"primitive","value":"Eisma, M.
