A Retrospective Lifespan Study of the Closest Sibling Relationship

Summary

Thirty-five women and 12 men, with a mean age of 59, were interviewed about the quality of their closest sibling relationships during seven periods of their life cycles. Interview responses were analyzed according to a seven-category coding system. Results revealed multidimensional developmental changes, such as greater perceived differentiation between siblings early in life and the provision of support during critical life events, such as the death of a parent. The study supported the feasibility of the coding system and suggests avenues of future cross-sectional and/or longitudinal research.
