青少年时期的自我伤害表明了严重的情感和心理痛苦。虽然关于自伤病因的数据有限，但目前的理论认为，在自伤青少年中观察到的情绪不稳定是个体生物学能力和环境风险之间复杂相互作用的结果。例如，多巴胺能功能的缺陷，加上某些家庭互动模式，可能会导致情绪不稳定和自我伤害的风险。作者探讨了典型（n = 21）和自伤（n = 20）青少年外周5-羟色胺水平和母子互动模式之间的关系。研究结果显示，较高水平的消极影响和较低水平的积极影响和家庭的凝聚力的自我伤害的参与者。外周5-羟色胺也与二分体内积极情感的表达相关。此外，青少年的5-羟色胺水平与消极情绪和冲突的二人组相互作用，解释了64%的自伤方差。这些发现强调了在理解和治疗自伤青少年时考虑生物和环境风险因素的重要性。
Self-inflicted injury in adolescence indicates significant emotional and psychological suffering. Although data on the etiology of self-injury are limited, current theories suggest that the emotional lability observed among self-injuring adolescents results from complex interactions between individual biological vulner-abilities and environmental risk. For example, deficiencies in serotonergic functioning, in conjunction with certain family interaction patterns, may contribute to the development of emotional lability and risk for self-injury. The authors explored the relation between peripheral serotonin levels and mother-child interaction patterns among typical (n = 21) and self-injuring (n = 20) adolescents. Findings revealed higher levels of negative affect and lower levels of both positive affect and cohesiveness among families of self-injuring participants. Peripheral serotonin was also correlated with the expression of positive affect within dyads. Furthermore, adolescents' serotonin levels interacted with negativity and conflict within dyads to explain 64% of the variance in self-injury. These findings underscore the importance of considering both biological and environmental risk factors in understanding and treating self-injuring adolescents.
