Abstract

Aim

This study aimed to investigate emotion regulation difficulties and executive functions of adolescent outpatients with skin picking disorder (SPD).

Method

Ninety six adolescents with SPD and ninety healthy controls were included in the study. All patients were diagnosed with SPD as per the diagnostic criteria of DSM-5. A battery of tests were implemented to evaluate emotional regulation strategies (i.e. acceptance,), as well as associations between those strategies and executive functions, and clinical variables (anxiety, depressive symptoms, impulsivity and illness characteristics).

Results

The SPD group had significantly higher scores in inhibition (t = 2.982, p = 0.030), emotional control (t = 2.461, p = 0.016), and planning-organization (t = 2.139, p = 0.038) Multiple linear regression model explained a considerable amount of variance of executive functions in the patient group (Adjusted R²=66.4%). In the patient group, age at illness-onset and the severity of inhibiton were significantly associated with the disruptions in emotional control functions (For age at illness-onset, β= −0.45, t=-3.0, p = 0.012 and for BRIEF Inhibition scores, β = 0.31, t = 2.8, p = 0.008).

Conclusion

The results of this study suggest that those with SPD have more emotion regulation problems and poorer executive function skills compared to those without SPD. Deficits in emotional control were associated with inhibition process and age-onset of the illness.

青少年皮肤采摘障碍的情绪调节和执行功能

摘要

目的

本研究旨在调查青少年门诊皮肤抠毛障碍（SPD）患者的情绪调节困难和执行功能。

方法

该研究包括 96 名患有 SPD 的青少年和 90 名健康对照者。所有患者均符合DSM-5诊断标准诊断为SPD。进行了一系列测试来评估情绪调节策略（即接受），以及这些策略与执行功能和临床变量（焦虑、抑郁症状、冲动和疾病特征）之间的关联。

结果

SPD 组在抑制（ t  = 2.982，p  = 0.030）、情绪控制（t  = 2.461，p  = 0.016）和计划组织（t  = 2.139，p  = 0.038）方面得分显着较高。患者组的执行功能存在相当大的差异（调整后的R ² =66.4%）。在患者组中，发病年龄和抑制的严重程度与情绪控制功能的破坏显着相关（对于发病年龄，β = -0.45，t = -3.0，p  = 0.012，对于短暂抑制，β = -0.45，t = -3.0，p = 0.012分数，β = 0.31，t  = 2.8，p  = 0.008）。

结论

这项研究的结果表明，与没有 SPD 的人相比，患有 SPD 的人有更多的情绪调节问题和更差的执行功能技能。情绪控制缺陷与抑制过程和发病年龄有关。
