Abstract
Association between resilience and neurocognitive performance
By Aliza P. Wingo
Background: Whether psychological resilience
correlates with neurocognitive
performance is largely unknown. Therefore, we assessed association
between
neurocognitive performance and resilience in individuals with a
history of
childhood abuse or trauma exposure.
Methods: In this cross-sectional study of 226 highly
traumatized civilians, we
assessed neurocognitive performance, history of childhood abuse and
other
trauma exposure, and current depressive and PTSD symptoms.
Resilience was
defined as having ≥ 1 trauma and no current depressive or
PTSD symptoms; non-
resilience as having ≥ 1 trauma and current moderate/severe
depressive or PTSD
symptoms.
Results: The nonresilient group had a higher percentage of
unemployment (p =
0.002) and previous suicide attempts (p <0.0001) than the
resilient group. Both
groups had comparable education and performance on verbal
reasoning,
nonverbal reasoning, and verbal memory. However, the resilient
group
performed better on nonverbal memory (p=0.016) with an effect size
of 0.35.
Additionally, more severe childhood abuse or other trauma exposure
was
significantly associated with non-resilience. Better nonverbal
memory was
significantly associated with resilience even after adjusting for
severity of
childhood abuse, other trauma exposure, sex, and race using
multiple logistic
regression (adjusted OR=3.21; p=0.01).
Conclusions: We examined resilience as absence of psychopathology
despite
trauma exposure in a highly traumatized, low socioeconomic, urban
population.
Resilience was significantly associated with better nonverbal
memory, a measure
of ability to code, store, and visually recognize concrete and
abstract pictorial
stimuli. Nonverbal memory may be a proxy for emotional learning,
which is
often dysregulated in stress-related psychopathology, and may
contribute to our
understanding of resilience.
