How do high-quality sibling relationships characterized by closeness influence individuals' well-being across the adult life span?

• A. They are associated with lower levels of well-being.
• B. They have no measurable effect on well-being.
• C. They are associated with higher levels of well-being.
• D. They only affect well-being in childhood.

Answer: (C)

Positive, high-quality sibling relationships provide ongoing social support and a sense of belonging that lasts across adulthood. When siblings are close, they offer emotional support during life transitions, help with practical needs, and reinforce resources for coping with stress. This kind of supportive network is linked to greater life satisfaction, lower levels of depression and anxiety, and overall higher well-being as people age. The impact persists across the adult life span, contributing to resilience and a stable sense of identity and connectedness. So, close, well‑connected sibling ties are associated with higher levels of well-being. If relationships are strained or distant, the effect can be the opposite, but the positive, long-term association is what the question emphasizes.
