Very little is known about the cognitive functioning of people with body-focused repetitive behaviours and the few existing studies provide mixed findings. The aim of this study was to investigate the interplay between attentional control, negative affectivity, and focused skin picking. We hypothesized that the control of attention is associated with focused style of skin picking and that this relationship is moderated by negative affectivity. The final sample consisted of 273 non-clinical subjects (79% women) aged 18 to 54 years; study variables were assessed using questionnaires. Moderation analysis was conducted, followed by a simple slope analysis, and the Johnson-Neyman technique was used to probe the interaction effect. We found that at the low level of negative affectivity, the relationship between attentional control and focused skin picking is negative, but not at the higher levels of this trait. Interestingly, when negative affectivity reaches very high intensity, the association between attentional control and skin picking becomes positive. This relationship seems to be quite complex and may depend on the way that cognitive abilities are used by the individual, as well as on the stage of cognitive processing that they are applied to. Further studies using behavioural measures of attention are needed to better understand this issue.
人们对具有身体关注重复行为的人的认知功能知之甚少，少数现有研究提供了混合的结果。本研究旨在调查注意力控制、消极情感和专注性皮肤搔抓之间的相互作用。我们假设注意力控制与专注性皮肤搔抓方式有关，这种关系受到消极情感的调节。最终样本包括 273 名非临床受试者（79%为女性），年龄在 18 至 54 岁之间；使用问卷评估研究变量。进行了调节分析，随后进行了简单斜率分析，并使用 Johnson-Neyman 技术探测交互作用。我们发现，在消极情感水平较低的情况下，注意力控制和专注性皮肤搔抓之间的关系是负相关的，但在该特质的较高水平上则不是。有趣的是，当消极情感达到非常高的强度时，注意力控制和皮肤搔抓之间的关联变为正相关。这种关系似乎相当复杂，可能取决于个体使用认知能力的方式，以及它们应用于认知加工的阶段。需要使用注意力的行为测量进一步研究来更好地理解这个问题。
