Schizoid Personality Disorder Checklist
This is a checklist to help one understand Schizoid Personality Disorder. One may use it to self-diagnose or as a worksheet to present to a doctor or therapist  or other medical professional and better communicate symptoms they are experiencing. All information is taken from the DSM-5.
Section I
Must check TWO or more of the following:
I have cognition problems and difficulty perceiving myself, other people, and events.
I have affectivity problems and difficulty controlling the range and intensity of my emotional responses.
I have problems with interpersonal functioning and being aware of my own actions and feelings.
I have difficulty controlling my impulses.
Section II
Must check FOUR or more of the following:
I donât enjoy close relationships at all, including being part of a family.
I prefer solitary activities which donât involve communicating with others.
I have little or no interest in having intimate experiences with another person. (OPâs note: The DSM actually says âsexualâ experiences, but I feel this excludes asexual people and attempts to pathologize asexuality, so I change the wording to âintimateâ to include closeness in any kind of relationship.)
I donât enjoy a lot of activities, and itâs difficult for me to be interested in anything.
I have no close friends or confidants other than maybe first-degree relatives.
I am pretty much indifferently to both praise and criticism from others.
I am emotionally cold and incredibly detached.
Section III
Must check ALL of the following:
My symptoms impair my personality and social functioning
My symptoms are consistent across a broad range of personal and social situations.
My symptoms have lasted a while and started in early adulthood or earlier.
My symptoms are not caused by medication, drug use, or another medical condition.
My symptoms are not better explained by schizophrenia, an episode caused by bipolar disorder, or autism spectrum disorder.
Section IV
Common symptoms ad behaviors (not required for diagnosis):
I am not a very expressive person at all.
I am the ultimate introvert, in that I do not like spending time with other people at all most of the time.
I feel I am less sensitive in my five senses as well.
My feelings are not easily hurt.
I have difficulty relating to others and understanding them.
I donât pick up well on social cues.
Iâm never sure how to react in social situations, and I find myself sticking to simple movements (such as smiling and nodding).
I rarely express my feelings to others.
I find social situations incredibly distressing.
I have difficulty expressing anger, even when someone is confronting me directly.
I have difficulty setting goals for myself, and I feel like I drift through life.
I can usually work very diligently on a task if I am left alone to my own devices and do not have to work on a team.
I experience psychotic episodes.
I am often depressed and/or anxious.
I am far more passive than assertive.
If you did not the minimum requirement for diagnosis, other disorders to look into include other disorders on the schizophrenia spectrum, anxiety disorders (especially Social Anxiety Disorder), Autism Spectrum Disorder, and depressive disorders. If you met the criteria for Sections I and III, you may want to look into other personality disorders.
