Psychiatric disorders are often associated with disturbed sleep. Poor sleep can attenuate emotional control, including the regulation of aggression, and thus, may increase the risk of impulsive, aggressive acts. This cross-sectional study aimed to investigate the potential contribution of sleep problems to subjective and objective aggressiveness and impulsivity in a forensic psychiatric population. Questionnaires on sleep quality (Pittsburgh Sleep Quality Index), chronic severe insomnia (Sleep Diagnosis List), aggressiveness (Aggression Questionnaire) and impulsivity (Barratt Impulsiveness Scale-11) were completed by 96 forensic psychiatric inpatients, admitted to two forensic facilities in the Netherlands. To obtain more objective measurements of aggression and impulsivity, observational scores on a professional instrument to assess the risk of future aggression (Historical Clinical Future-30) and reported aggressive incidents were collected from files. Results showed that a worse sleep quality and higher insomnia scores were significantly associated with self-reported aggression and impulsivity, clinician-rated hostility and involvement in aggressive incidents within the facility. Whether a participant was professionally judged as impulsive could not be predicted by sleep quality or the insomnia score. To a large extent the results of this study support the hypothesis that poor sleep is related to impulsive, aggressive behavior in forensic psychiatric patients. It is worthwhile to examine the protective effect of treatment of sleep difficulties on aggressive reactivity in (forensic) psychiatric populations.
This research output has an Altmetric Attention Score of 12. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 November 2023.
All research outputs
#3,778,485
of 32,282,066 outputs
Outputs from Physiology & Behavior
#980
of 5,740 outputs
Outputs of similar age
#30,167
of 250,123 outputs
Outputs of similar age from Physiology & Behavior
#6
of 20 outputs
Altmetric has tracked 32,282,066 research outputs across all sources so far. Compared to these this one has done well and is in the 88th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 5,740 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 15.4. This one has done well, scoring higher than 82% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 250,123 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 87% of its contemporaries.
We're also able to compare this research output to 20 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 70% of its contemporaries.
