摘要

Drive for muscularity (DM) is a form of body image disturbance that is particularly evident in males and may be influenced by the timing of pubertal onset. Indeed, pubertal maturation results in the development of characteristics perceived as masculine, such as body hair growth and deepening of the voice, as well as decreases in body fat and increases in muscle mass. These physical changes move males closer to attaining physical attributes associated with masculinity and the socially prescribed muscular body ideal. Males who mature later than peers may therefore be at a heightened risk for DM, given their delay in physical/masculine maturation. This study aimed to evaluate the potential long-term impact of later pubertal timing on DM by examining associations between pubertal timing and DM in 255 men (M-age = 20.99, SD = 4.14). The Retrospective-Pubertal Development Scale assessed perceived and objective reports of pubertal timing. The Drive for Muscularity Scale and the Eating Pathology Symptoms Inventory assessed behavioral and cognitive aspects of DM. Later pubertal timing was predictive of DM; however, significant effects were largely only present for behavioral aspects of muscle building and when objective reports of pubertal timing (e.g., age of onset), rather than perceived timing, were used. The findings suggest that later pubertal timing may exhibit some differential effects on various types (behavioral vs. cognitive) of DM symptoms, and objective indicators of pubertal timing may be more sensitive to detecting timing-DM associations, at least in adulthood.
