Environmental Influences of OCD
The environment in which you live plays an influential role on the development of OCD. Common environmental influences of OCD include upbringing, family and other significant relationships and stress and traumatic external events. Having a family history of OCD may increase the likelihood that you will also suffer from this disorder.
Upbringing may play a significant role in the development of OCD, according to BBC Health. For example, when you were a child, if your parents consistently judged your actions as either all good or all bad, you may have an overdeveloped, internalized sense of right and wrong. If you did something you knew was wrong and you were harshly punished for it, you may have developed obsessions or compulsions to avoid the thought that you were "wrong" or "bad." You may have developed obsessive thought patterns such as, "I mustn't be bad, I must always be good," and developed behaviors to support these thoughts.
Stress is another of the key environmental influences of OCD. If you react strongly to stressful events, you may have an increased likelihood of developing OCD. Traumatic events such as the death of a loved one or frightening events in the news can also cause an increase in OCD behaviors and thoughts in an attempt to keep your worries at bay. For example, if you have an unrealistic, unfounded worry that your house is going to go on fire if you leave the house, and you see a story on the news that someone's house burned down, you may focus on obsessive behaviors such as constantly checking the stove to make sure you turned it off.
