Depression 3 Flashcards
Catastrophizing
You expect disaster, you filter the decisions through “what if?”. What bad thing can happen? What if it happens to you?
Personalization
- You think that everything people do or say is some kind of reaction to you
- Constantly compare yourself to others (thinner, smarter, more popular, etch)
Polarized thinking
Black and white thinking - you are either with or against me
(ex. If you are less than perfect you are a failure, if I don’t get all A’s, I’m a failure)
Shoulds: cognitive distortion
- List of Ironclad rules
- Angry with people who break them and feel guilty for violating them
Overgeneralization
Coming to a conclusion based on a single incidence or piece of evidence
(ex: I failed that test, I am a failure as a student. OR I got rejected, I will never reach out again)
Cognitive distortion: mental filtering
We pick out a negative detail and focus on that thought & filter out all the positive aspects of that situation
Cognitive distortion: blaming others
You hold of the people responsible for your pain and misfortune
Cognitive distortion: Heaven’s reward fallacy
- Expect all your self-sacrifice to pay off as if there were some one’s keeping score
- You become bitter or sad when the reward doesn’t come
Cognitive distortion: inappropriate expectations of others
- You think other people will change if you are convincing her pleasing enough
- You need other people to change because your own happiness is dependent on them
Cognitive distortion: ignoring the positives
You reject anything positive that does not support your thought (ex: “ that doesn’t count because…”)
Cognitive distortions: minimization
You undervalue your own positive qualities
