Voluntary visual imagery and non-suicidal self-injury in patients with emotionally unstable personality disorder
This study found that patients with Emotionally Unstable Personality Disorder who engage in non-suicidal self-injury exhibit significantly greater voluntary visual imagery vividness, which is specifically associated with the intrapersonal function of affect regulation rather than interpersonal motivations.

The Big Picture: A "Mental Movie" Study
Imagine your mind is a cinema. For some people, when they close their eyes and think of a beach, they see a black-and-white sketch. For others, they see a 4K, high-definition movie with sound and smell. This study looked at the "cinema quality" (visual imagery) inside the minds of people with Emotionally Unstable Personality Disorder (EUPD)—a condition where emotions can feel like a rollercoaster that's hard to control.
The researchers wanted to know: Does having a super-vivid mental movie make it more likely for someone to hurt themselves (without trying to die) to cope with those emotions?
The Cast and The Setup
- The Participants: The study looked at 40 adults diagnosed with EUPD. Most were women.
- The "Mental Movie" Test: They used a questionnaire called the VVIQ-2. Think of this as a test where you are asked to picture 32 different scenes (like a sunset or a birthday cake) and rate how clear the picture is in your head.
- Low Score: Your mental screen is foggy or blank (like a broken projector).
- High Score: Your mental screen is crystal clear (like a IMAX theater).
- The "Self-Harm" Test: They also asked about Non-Suicidal Self-Injury (NSSI). This is when someone hurts themselves (like cutting or hitting) to deal with emotional pain, not to end their life. They asked why they did it (e.g., to stop feeling numb, to punish themselves, or to calm down).
What They Found: The "High-Definition" Connection
The study discovered a strong link between having a very clear mental movie and the act of self-harm.
The Clearer the Movie, The More Likely the Harm:
People who reported hurting themselves had significantly higher scores on the mental imagery test than those who didn't.- Analogy: Imagine two people trying to handle a loud, chaotic noise. One person has a quiet room (low imagery), while the other has a room with giant speakers blasting the noise (high imagery). The study suggests that the person with the "loud speakers" in their head (vivid imagery) was more likely to try to "turn off the volume" by hurting themselves.
It's About Internal Feelings, Not Other People:
The vividness of the mental images was linked specifically to internal reasons for self-harm, such as regulating emotions or stopping a feeling of being disconnected from reality. It was not linked to doing it to get attention or influence others.- Analogy: If your mental movie is so intense and emotional that it feels overwhelming, you might hurt yourself just to "reset the system" and feel something real, rather than to show anyone else what's happening.
The "Super-Visual" Group:
About 7.5% of the patients had imagery so vivid it was classified as "probable hyperphantasia" (the extreme opposite of "aphantasia," where you can't see anything in your mind). Another 25% had "high" imagery. None of the patients had the "blank screen" (aphantasia) type.Synesthesia (The "Mixing Senses" Effect):
A few participants reported "synesthesia-like" experiences. This is when senses get mixed up, like seeing the color red when you hear a specific word. While a few people reported this, the study noted this finding is preliminary because the group was small.
What the Paper Does Not Say
It is important to stick to what the researchers actually found:
- It's a Snapshot, Not a Movie Script: The study shows a connection (correlation), but it doesn't prove that vivid images cause the self-harm. It's like seeing that people with umbrellas are often wet; the umbrella didn't cause the rain, but they are linked. We don't know if the vivid images cause the pain, or if the pain causes the images to get louder.
- No Control Group: The study only looked at people with EUPD. They didn't compare them to a group of healthy people to see if EUPD patients have more vivid images than everyone else.
- No Treatment Advice Yet: While the authors suggest this might be useful for future therapy, this specific paper does not test any new treatments or claim that changing how people visualize things will stop the self-harm.
The Takeaway
This research suggests that for some people with EUPD, their internal "mental movies" are incredibly vivid and intense. This high-definition experience seems to be tied to the urge to hurt oneself as a way to manage overwhelming internal emotions. The study highlights that how we "see" things in our minds might be a missing piece of the puzzle in understanding why some people struggle so much with emotional regulation.
