Researchers have suggested that the symptoms of posttraumatic stress disorder (PTSD) should be divided into the four dimensions of intrusions, avoidance, numbing or dysphoria, and hyperarousal. However, the clinical utility of a dysphoria/general distress symptom dimension is unclear, and measures of the overall structure of PTSD are limited by the small number of avoidance and prototypical hyperarousal symptoms in the Diagnostic and Statistical Manual of Mental Disorders (DSM). The Iowa Traumatic Response Inventory (ITRI) was created as a broader measure of symptoms related to PTSD. The factor analytic method of test construction was used to create the scales from a larger pool of items. The measure was validated in a clinical sample and in a student sample. Analysis of the ITRI symptom dimensions suggests traumatic intrusions and avoidance symptoms are highly associated and are specific to PTSD, whereas dysphoria, hyperarousal, and dissociation are not specific to PTSD. Overall, the ITRI was found to be a reliable and valid measure of PTSD symptoms that better captures the observed structure of the disorder.
This research output has an Altmetric Attention Score of 1. 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 25 February 2015.
All research outputs
#15,325,572
of 22,793,427 outputs
Outputs from Assessment
#507
of 810 outputs
Outputs of similar age
#133,113
of 227,738 outputs
Outputs of similar age from Assessment
#10
of 17 outputs
Altmetric has tracked 22,793,427 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 810 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.3. This one is in the 26th percentile – i.e., 26% of its peers scored the same or lower than it.
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 227,738 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 32nd percentile – i.e., 32% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 17 others from the same source and published within six weeks on either side of this one. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
