Jeff Szymanski, PhD (ocfoundation.org) Obsessions: Thoughts, images, or impulses that occur over and over again and feel out of the person’s control. The person does not want to have these ideas. He or she finds them disturbing and unwanted, and usually knows that they don’t make sense. They come with uncomfortable feelings, such as fear, disgust, doubt, or a feeling that things have to be done in a way that is “just right.” They take a lot of time and get in the way of important activities the person values. Compulsions: Repetitive behaviors or thoughts that a person engages in to neutralize, counteract, or make their obsessions go away. People with OCD realize this is only a temporary solution, but without a better way to cope, they rely on the compulsion as a temporary escape. Compulsions can also include avoiding situations that trigger obsessions. Compulsions are time consuming and get in the way of important activities the person values.

Jonathan Abramowitz, PhD (jabramowitz.com) Common obsessions include: fears of contamination/germs, causing harm (perhaps by hitting someone with a car that you don’t mean to), making mistakes (leaving the door unlocked), disasters (causing a fire), certain numbers (such as 13 and 666), unwanted violent thoughts (thought of harming a loved one), blasphemous thoughts (cursing God), sexual thought (what if I’m a child molester, gay, or want to have sex with my mother?), need for symmetry and exactness, and thoughts that something is terribly wrong with your body (what if I have cancer?). A general theme is that obsessions concern situations where there is some degree of uncertainty (what if “X” happens and I didn’t do enough to prevent it?) Compulsive rituals are all about trying to get reassurance and certainty. For example, washing to remove germs, praying to counter blasphemous or sacrilegious thoughts that could result in going to hell, checking for assurances that doors are locked or people are OK, putting things in order (arranging), repeating other behaviors to get rid of a thought (turning a light off and on until a bad thought goes away). Also common are mental rituals that take place purely in the person’s mind. Steven J. Brodsky, PsyD (OCDHotline.com) There are thousands of forms of OCD, as unique as each individual. They are not limited to the ones you see on TV with themes of checking, germaphobic cleaning, ordering, perfectionism, hoarding, and hypochondriasis, etc. They can also involve body dysmorphic disorder, scrupulosity, religious OCD, relationship OCD (ROCD) in which people wonder if they love their partner or vice versa, HOCD (homosexuality OCD) in which the sufferer doubts his or her sexual orientation. OCD can even take a nonsense form, with unanswerable metaphysical questions, a song that sticks in your mind, thinking about one’s swallowing or blinking, etc. Charles H. Elliott, PhD, and Laura L. Smith, PhD (psychology4people.com) Common obsessions include fears about contamination, worries about having left appliances on or doors unlocked, fear of acting in shameful or humiliating ways, discomfort about things being out of order, extreme concerns about superstitions such as unlucky numbers or colors, and excessive worries about keeping objects of all kinds. Common compulsions include excessive cleaning and hand washing; repeatedly checking doors, locks, appliances, and such; rituals designed to ward off contact with superstitious objects; using prayers or chants to prevent bad things from happening; arranging and rearranging objects; and hoarding huge numbers of ordinary objects. Kenneth Schwarz, PhD (DutchessPsychology.com) Some common obsessions have to do with becoming contaminated, being or becoming too aggressive, having persistent sexual thoughts, being susceptible to injury or disease. There is also religious scrupulosity, where a person has unwanted, blasphemous thoughts that she must work hard to keep under control, and out of her mind, so she doesn’t just blurt them out - which is what makes her so anxious. The common element in all these obsessions are persistent, unwanted thoughts that cause a person considerable anxiety. Common compulsions used to get rid of these obsessions come under the headings of checking, cleaning, decontamination rituals, counting, and putting or keeping things in a certain order. Charlotte M. Scott (custommovesolutions.com) Common obsessions and compulsions that many are familiar with include the fear of germs and sickness, constant hand washing, using bleach wipes to handle everyday objects that other people have touched, and an overwhelming compulsion to clean and possibly hoard. A person may be filled with anxiety walking across a soccer field and seeing orange peels, candy wrappers, or empty water bottles and desperately wants to rid the field of the trash and clutter, yet the stronger obsession of not touching the items because of germs and bacteria creates the need to control others to pick up the items. Many people with OCD become hoarders triggered by the death of a loved one and the feeling that they must keep everything to protect the memories. Barbara Tako (clutterclearingchoices.com) Someone with OCD might be afraid to throw anything away and have strong emotional attachments to many things they own. On the other end of the scale, someone with OCD might turn down a coffee date or other social activity to stick with their cleaning schedule. Allen H. Weg, EdD (stressandanxiety.com) The most common obsessions are worries that something is “contaminated” which results in excessive avoidance or excessive washing. Another common compulsion is checking behavior, which results when a person’s obsession makes him not feel sure about something (e.g., “Is it locked?” “Is it turned off?” “Did I leave that thing behind?”) Other obsessions may have to do with sexual identity (“Am I gay?”) which results in attempts to seek reassurance that one is not gay. Also, fear of loss of impulse control, or a sense that one will act out and do something “crazy,” resulting in obsessions such as “maybe I will grab a knife and kill someone before I realize what I am doing,” or " maybe I will just fling my body off of a high place and kill myself.” These obsessions result in people avoiding sharp objects or knives, or places of perceived danger, such as the kitchen, or high places. Besides Checkers, Hoarders, and Aggressive OCD, as depicted above, there is also ordering OCD, counting OCD, symmetry OCD, and hoarding OCD (though research has of late been demonstrating that this last form may be a different disorder altogether).
