摘要

Our study aimed to develop a standardized set of images designed to provoke symptoms relevant to different types of obsessive–compulsive disorder (OCD), alongside a matched neutral stimuli set. We validated a collection of symptom-related stimuli in OCD, categorized into four types (“Aggression”, “Checking,” “Contamination,” and “Symmetry”), and created a neutral set by pixelating randomly selected images from each type in 32 neurotypical volunteers and 25 individuals with OCD. To ensure robustness, we analyzed the physical characteristics of both the symptom-related stimuli in OCD and neutral images. The resulting OCD-triggering image set (OCD-TIS) provides a validated resource for researchers studying OCD, offering a tool to investigate symptom provocation and associated physiological responses. This work contributes to the growing body of research aimed at understanding the mechanisms underlying OCD and developing targeted interventions.
