Abstract:  
This research is dedicated to the problem of examination of psychological determinants of longevity and aging, in the context of seeking correlation between the meaningful relationships in life of a person and the rate of biological and psychological aging. The article analyzes the current state of the problem including a summary of biological and socio-psychological factors classified as the determinants of aging. It is noted that in modern research dedicated to longevity and aging, the priority of biological sciences is fading away due to accumulation of important data on the social and psychological factors of aging. Based on correlation of various theories of aging, the authors substantiate the possibility of determining interpersonal relationship as an important resource of life expectancy. Emphasis is placed on the basic (child-parent, family) and meaningful relationships of a person (friends, colleagues, neighbors, likeminded people). The conducted empirical research allowed revealing a number of essential correlations of satisfaction in basic and meaningful relationships with the parameters of biological and psychological age, as well as rate of biological and psychological aging. Biological and psychological aging is more apparent for people who consider relationships with parents and friends an important value, while experience lots of dissatisfaction in relationships with siblings, neighbors and like-minded individuals. The article reveals the pattern of dependence between the quality of relationship with the father and psychological and physiological aging rate: father’s involvement in child’s life may contribute to longer preservation of physical and psychological forcefulness, preventing premature aging.
