Abstract

Objective:

The aim of this work was to examine the relationship between strangulation-related alterations in consciousness (AIC) and cognitive and psychological outcomes in women who have experienced intimate partner violence (IPV).

Setting:

Participants were recruited from a variety of settings, including women's shelters and support programs.

Participants:

A total of 99 women were enrolled in the study. After applying exclusion criteria for factors that could mask or confound the effects of strangulation, 52 women remained for analyses.

Design:

Cross-sectional, retrospective.

Main Measures:

We used several cognitive measures to assess learning, long-term and working memory, visuomotor speed, cognitive flexibility, and nonverbal cognitive fluency as well as several psychological measures to assess posttraumatic stress symptomatology, general distress, worry, anhedonic depression, and anxious arousal. We also used the Brain Injury Severity Assessment interview to examine the association between strangulation-related AICs and these measures of cognitive and psychological functioning.

Results:

Women who had experienced strangulation-related AICs performed more poorly on a test of long-term memory (P < .03) and had higher levels of depression (P < .03) and posttraumatic stress symptomatology (P < .02) than women who had not experienced strangulation-related AIC. When controlling for potential confounding variables, including number of IPV-related traumatic brain injuries, women who had experienced strangulation also performed more poorly on a measure of working memory.

Conclusion:

This is the first report to assess strangulation in this manner and demonstrate links to cognitive and psychological functioning. These preliminary data contribute to our knowledge of strangulation and its effects on women who have experienced IPV.

Relationship Formation

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Traumatic Memory

Traumatic Memory

Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

Dissociative Disorders

Dissociative Disorders

Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.
Dissociative Fugue
A hallmark feature of dissociative disorders is the dissociative fugue...
