The predictive role of chronic stress and sensory processing sensitivity in risky decision function in patients with multiple sclerosis

The aim of this study is the prediction of the executive function of risky decision making, base on chronic stress and sensory processing sensitivity components in patients with multiple sclerosis. A sample of 200 patients (49 males and 151 females) of the Iranian MS Association completed the Chronic Stress Scale (CSS), the Sensory Processor Sensitivity Test, and the Iowa Gambling Test (IGT) Stepwise regression showed that the low sensory threshold predicts risky decision making in the first step. In the second and third steps, the low sensory threshold decreased with the introduction of chronic stress and the ease of stimulating the predictive power of the low sensory threshold. The predictive power of sensory thresholds, chronic stress, and ease of stimulation in predicting risky decisions increased. The results of this study showed that chronic stress and low sensory threshold dimensions, ease of stimulation and aesthetics, predict the role of risky decision making in MS patients.
