The Relationship Between Sensory Processing and Attachment Patterns: A Scoping Review

Background. Clinicians and researchers have observed that sensory processing and attachment difficulties frequently co-occur; however, little is known about which sensory processing and attachment patterns are interrelated across populations. Purpose. To review evidence of empirical relationships between sensory processing and attachment patterns across the life span. Method. Using the Arksey and O'Malley framework, four databases were searched up to June 2021 for studies that investigated relationships between sensory processing and attachment patterns. Findings. Twenty-two studies met inclusion criteria: nine considered sensory and attachment patterns in children/adolescents and thirteen in adults. In children, sensory modulation was positively associated with attachment security. In adults, more extreme patterns of sensory modulation (e.g., higher sensory sensitivity) were generally associated with attachment insecurity. Implications. Findings indicate empirical relationships between sensory processing and attachment constructs in children and adults that warrant further investigation. Occupational therapists should consider both sensory processing and attachment patterns when planning interventions.
