Current approaches to somatic symptom perception conceptualize somatic symptoms partly as somato-visceral or body illusions evoked by an interaction between bottom-up (sensory) and top-down (expectations, attention) processes. Similar processes of multisensory integration are assumed to contribute to the rubber hand illusion (RHI). Findings concerning the strength and direction of associations between these two phenomena, symptom perception and the RHI, are equivocal. Individuals of a non-clinical sample (N = 63; 56% females; M = 20.4; SD = 1.6) completed the Patient Health Questionnaire Somatic Symptom Scale (PHQ-15) and participated in an experiment that evoked the RHI. In repeated measures analyses of variance with the PHQ-15 score as covariate, no significant interaction effects between the PHQ-15 score and indicators of the RHI, i.e., proprioceptive drift (F(1,61) < 0.001 p = 0.993, partial η < 0.001; BF = 0.307), felt body ownership(F(1,59) = 0.043, p = 0.836, partial η = 0,001; BF = 0.501), and felt body disownership (F(1,59) = 0.148, p = 0.702, partial η = 0.002; BF = 1.972) were found. Overall, frequentist and Bayesian analysis indicated that the support for a possible association between the PHQ-15 and indicators of the RHI remains inconclusive, i.e., neither the null nor the alternative hypotheses were sufficiently supported. At least in this non-clinical sample, the association between somatic symptom distress and the strength of the RHI appears so weak (perhaps non-existing), that both phenomena (somatic symptom distress and the RHI) appear distinct and largely unrelated.
当前，躯体症状感知的研究方法部分地将躯体症状理解为躯体-内脏或身体错觉，这些错觉是由自下而上（感觉）和自上而下（期望、注意力）过程的相互作用引起的。类似的多感觉整合过程被认为有助于产生橡胶手错觉（RHI）。关于这两种现象（症状感知和 RHI）之间关联的强度和方向的研究结果尚无定论。一项非临床样本（N=63；56%为女性；M=20.4；SD=1.6）的研究中，个体完成了患者健康问卷躯体症状量表（PHQ-15）并参与了一个可以诱发 RHI 的实验。在以 PHQ-15 得分为协变量的重复测量方差分析中，PHQ-15 得分与 RHI 指标之间没有显著的交互作用，即本体感觉漂移（F(1,61) < 0.001，p=0.993，部分 η < 0.001；BF=0.307）、感觉身体所有权（F(1,59)=0.043，p=0.836，部分 η=0.001；BF=0.501）和感觉身体失所有权（F(1,59)=0.148，p=0.702，部分 η=0.002；BF=1.972）。总体而言，经典和贝叶斯分析表明，PHQ-15 和 RHI 指标之间可能存在关联的证据仍不明确，即，无论零假设还是备择假设都没有得到充分支持。至少在这个非临床样本中，躯体症状困扰与 RHI 强度之间的关联似乎很弱（可能不存在），这两种现象（躯体症状困扰和 RHI）似乎是不同的，且在很大程度上没有关联。
