Limited information is available concerning the specificity of the forms and functions of aggressive behavior exhibited by boys with fragile X syndrome (FXS). To investigate these relationships, we conducted indirect functional assessments of aggressive behavior exhibited by 41 adolescent boys with FXS and 59 age and symptom-matched controls with intellectual and developmental disability (IDD) and compared the data between groups. Results showed that boys with FXS were more likely to exhibit specific forms of aggressive behavior (i.e., scratching others and biting others) compared to controls, but the sources of reinforcement identified for aggression were similar across groups. Boys with FXS who were prescribed psychotropic medications were more likely to be older and to exhibit more forms of aggression. The implications for the treatment of aggressive behavior during this critical developmental period in FXS are discussed.

检查脆性 X 综合征男孩攻击行为的形式和功能的特异性。

关于患有脆性 X 综合征 (FXS) 的男孩表现出的攻击行为的形式和功能的特异性的信息有限。为了研究这些关系，我们对 41 名患有 FXS 的青春期男孩和 59 名年龄和症状匹配的智力和发育障碍 (IDD) 对照者表现出的攻击行为进行了间接功能评估，并比较了组间数据。结果表明，与对照组相比，患有 FXS 的男孩更有可能表现出特定形式的攻击行为（即抓挠他人和咬他人），但针对攻击性确定的强化来源在各组中是相似的。服用精神药物的 FXS 男孩更有可能变老并表现出更多形式的攻击性。
