To gain a deeper understanding of the factors influencing wisdom in old age, a study was conducted using the Experiences in Close Relationships Scale, Three-Dimensional Wisdom Scale, Zimbardo Time Perspective Inventory (Chinese version), and Perceived Social Support Scale. The survey included 349 elderly participants. The results indicated that: Attachment anxiety and attachment avoidance significantly negatively predict wisdom in old age. Present-fatalistic time perspective plays a significant moderating role in the impact of attachment anxiety and attachment avoidance on wisdom. Attachment anxiety significantly negatively predicts perceived social support, while perceived social support significantly positively predicts wisdom in old age. Perceived social support partially mediates the relationship between attachment anxiety and wisdom in old age. Present-fatalistic time perspective moderates the direct path (attachment anxiety → wisdom in old age) as well as both segments of the indirect path in the mediation model (attachment anxiety → perceived social support and perceived social support → wisdom in old age).This research enhances the understanding of the relationships between attachment, time perspective, perceived social support, and wisdom in old age. It can provide references for developing intervention measures targeting elderly individuals with different levels of attachment.
