Obsessive-Compulsive Disorder

At the OCD and Anxiety Treatment Center of Houston, treatment is available for all types of OCD.  These include fears of contamination, obsessions involving fear of harming, fear of inappropriate sexual behavior, and fears of violating religious or moral beliefs. Evidence based CBT treatments are used, primarily focusing on Exposure and Response Prevention (ERP) techniques, as well as Acceptance and Commitment Therapy (ACT) techniques as needed.

  • Excessive hand washing, cleaning
  • Avoiding touching things, (e.g., covering hands with sleeves to touch doorknobs)
  • Checking (e.g., checking stoves, light switches, or door locks; checking the road or car due to “hit and run” OCD)
  • Counting, repeating (e.g., having to repeat behavior 4 times or multiples of 4)
  • Ordering – arranging things, or having to create symmetrical a arrangements, having to do things that create even feelings on left and ride sides
  • Compulsive telling or confessing
  • Checking for reassurance with family members, doctors, or on websites

  • Relationship OCD: Fear that one is in the wrong relationship, in an otherwise good relationship, leading to checking for evidence to confirm one’s doubts
  • Aggressive thoughts: Thoughts of harming self or others, e.g., thoughts of stabbing loved one, when one has no desire to do so
  • Sexual thoughts: Fears of being gay, or fears of being straight, if one is gay; fears of molesting children, etc.
  • Scrupulosity, i.e., religious or moral obsessions: Fears of doing something bad or wrong, or fears of blaspheming God, or fears of being unfaithful, with compulsions to confess minor behavior (among Catholics), excessive praying, checking with clergy for reassurance, etc.
  • Indecisiveness: Fear of making the wrong decision, leading to reviewing all options, and avoiding making decisions
  • Sensorimotor OCD: Preoccupation with bodily sensations, e.g., blinking, breathing, heart rate
