The relationship between sensory processing, childhood rituals and obsessive-compulsive symptoms

Area of Science:

• Psychology
• Neuroscience
• Occupational Therapy

Background:

• Research suggests a connection between sensory hypersensitivity and ritualistic behaviors in Obsessive-Compulsive Disorder (OCD).
• Occupational therapy studies highlight potential links between sensory processing and OCD-related symptoms.

Purpose of the Study:

• To investigate the relationship between sensory hypersensitivity and ritualistic behaviors.
• To explore the potential role of sensory hypersensitivity as a pathway to adult OCD.

Main Methods:

• Study 1: Parents of 4-6-year-old children completed questionnaires on routines, sensory processing, and anxiety.
• Study 2: Adults (N=314) completed assessments of sensory hypersensitivity (current and recalled childhood) and OCD symptoms.

Main Results:

• Childhood sensory hypersensitivity strongly correlated with ritualism, independent of anxiety.
• Adults' current and recalled oral/tactile hypersensitivity were significantly associated with OCD symptoms.

Conclusions:

• A significant relationship exists between sensory sensitivity, childhood ritualism, and adult OCD.
• Childhood oral and tactile hypersensitivity may represent a developmental pathway to adult OCD.
