  • Avoiding Contact: Refraining from touching certain objects or surfaces perceived as dirty or contaminated.

  • Using Protective Measures: Wearing gloves or using other protective measures to avoid direct contact.

  • Excessive Use of Hand Sanitizers:

  • Dependency: Feeling compelled to use hand sanitizers as a means of feeling clean and safe.

  • Avoidance of Public Spaces:

  • Compulsive Scrubbing: Vigorously scrubbing the body to eliminate any perceived contaminants.


Characteristics of Hygiene-Related Compulsions:



  • Engaging in these hygiene rituals can be time-consuming, leading to disruptions in daily activities and routines.

  • Interference with Daily Life:

  • Compulsive hand washing and hygiene rituals can interfere with work, social activities, and relationships.

  • Physical Consequences:

  • Excessive hand washing and use of cleaning agents can lead to skin irritation, dryness, and even dermatological issues.

  • Temporary Relief:

  • While the compulsive behaviors provide temporary relief from anxiety, the distress typically returns, leading to a cycle of repetitive rituals.

Somatic checking compulsions in Obsessive-Compulsive Disorder (OCD) involve repetitive behaviors or mental rituals related to concerns about bodily sensations, health, or physical well-being. Individuals with somatic checking compulsions may be preoccupied with the fear of having a medical condition or experiencing harm to their body. Here are key aspects of somatic checking compulsions:

1. Obsessions:

a. Health Concerns:

  • Individuals with somatic checking compulsions often experience intrusive thoughts or fears about their health. These thoughts may involve worries about having a serious illness, experiencing physical harm, or developing symptoms.

b. Catastrophic Thinking:

  • Obsessions may include catastrophic thinking about the potential consequences of a perceived health issue. Individuals may fear the worst-case scenario, even when evidence suggests otherwise.

c. Hypervigilance:

  • Hypervigilance refers to excessive attention to bodily sensations or changes, with heightened sensitivity to any perceived abnormalities. Individuals may be hyperaware of minor discomforts or fluctuations in physical sensations.

2. Compulsive Behaviors:

a. Frequent Medical Checks:

  • Engaging in frequent medical check-ups, doctor visits, or health-related appointments to seek reassurance or confirmation of one's physical well-being.

b. Self-Examination:

  • Excessive self-examination or monitoring of the body, such as checking for lumps, bumps, or changes in appearance. This behavior is driven by the need to confirm the absence of a perceived health issue.

c. Online Health Research:

  • Compulsive searching for health information online to validate or invalidate concerns. Individuals may spend significant time seeking reassurance through medical websites, forums, or articles.

d. Temperature and Pulse Checks:

  • Frequent checks of body temperature, heart rate, or other physiological measures to ensure they fall within a perceived normal range. Individuals may monitor these parameters excessively to alleviate anxiety.

e. Avoidance of Triggers:

  • Avoidance of situations or activities perceived as potential health risks. Individuals may modify their behavior to reduce the likelihood of experiencing physical harm or triggering health-related anxiety.

3. Impact on Daily Life:

a. Interference with Daily Activities:

  • Somatic checking compulsions can interfere with daily activities, work, or social engagements as individuals dedicate significant time and energy to checking behaviors.

b. Anxiety and Distress:

  • The constant need for reassurance and checking behaviors can lead to heightened anxiety and distress. Individuals may struggle with persistent worries about their health despite repeated reassurance.

c. Health Anxiety:

  • Somatic checking compulsions contribute to health anxiety, where individuals are preoccupied with fears of having a serious illness or experiencing physical harm.


Treatment Approaches:

a. Exposure and Response Prevention (ERP):

  • ERP, a key component of cognitive-behavioural therapy (CBT) for OCD, involves exposing individuals to situations that trigger health-related obsessions and preventing engagement in compulsive checking behaviors. This helps individuals learn to tolerate uncertainty and reduce the need for reassurance.

b. Cognitive Restructuring:

  • Cognitive restructuring focuses on challenging and changing maladaptive thought patterns associated with health-related fears. This includes addressing cognitive distortions and developing a more balanced perspective on bodily sensations.

c. Mindfulness-Based Approaches:

  • Mindfulness techniques can help individuals observe bodily sensations without excessive anxiety, reducing the urge to engage in compulsive checking behaviours.

​Cognitive-Behavioural Therapy (CBT):

  • Exposure and Response Prevention (ERP) is a key component of CBT, involving gradual exposure to feared contaminants without engaging in the compulsive behaviours.

  • Mindfulness-Based Approaches:

  • Mindfulness techniques can help individuals become more aware of their thoughts and sensations without acting on compulsions.

  • Gradual Reduction of Rituals:

  • Working with a therapist to develop a step-by-step plan to gradually reduce the frequency and intensity of compulsive behaviours.
