abstract="Childhood adversities are associated with compromised behavioral health later in life. However, less attention has been paid to how time contributes to the damaging  effects of adversity exposure. In addition, the differential impact of childhood  maltreatment and household dysfunction has been understudied. The current study  tested (a) the sensitive period hypothesis regarding timing of childhood adversity  on externalizing behavior, (b) the accumulation hypothesis regarding the  associations between the duration of childhood adversity and externalizing behavior,  and (c) the domain-specific impact of childhood adversity on externalizing behavior. Data came from the Young Women and Child Development Study (N = 240). Childhood  adversity was measured at seven periods (age range: 5.5-16), which were used to test  the sensitive period hypothesis. Childhood adversity at each time period was summed  across seven time periods to test the accumulation measure representing the duration  of childhood adversity. Least angle and multiple regression analyses were conducted. <br><br>RESULTS supported the sensitive period hypothesis-the effect of childhood adversity  was the most prominent at age 11.5, whereas the accumulation of childhood adversity  time periods was not a significant predictor of later externalizing behavior. Probing childhood adversity by subdomains revealed maltreatment primarily accounted  for externalizing behavior (p <.05). <br><br>FINDINGS suggest intervention efforts for  children of teen mothers during early adolescence to prevent externalizing behavior  in later adolescence. Unpacking childhood adversity may illuminate key areas of  vulnerability to externalizing behavior.<p /> <p>Language: en</p>",
