The questionnaires used in this study were the Obsessive-Compulsive Inventory (OCI) for obsessive-compulsive disorder, the trait portion of the State-Trait Anxiety Inventory (STAI) for trait anxiety, the Self-Rating Depression Scale (SDS) for depression, the Perceived Stress Scale (PSS) for stress, and the Barratt Impulsivity Scale 11th version (BIS-11) for impulsivity. The correlations of their scores with the model parameters are shown. Model parameters were estimated using the parallel model (P), the parsimonious learning-rate adjustment model (LA), the P model in which μ is a free parameter (P-FD), or the LA model in which μ is a free parameter (LA-FD). Italic: p < 0.10. Bold: p < 0.05.
