[EX Q]: Context: Survivors of acute respiratory failure commonly experience long-term psychological sequelae and impaired quality of life. For researchers interested in general mental health, using multiple condition-specific instruments may be unnecessary and inefficient when using the Medical Outcomes Study Short Form (SF)-36, a recommended outcome measure, may suffice. However, relationships between the SF-36 scores and commonly used measures of psychological symptoms in acute survivors of respiratory failure are unknown. Our objective is to examine the relationship of the SF-36 mental health domain (MH) and mental health component summary (MCS) scores with symptoms of depression, anxiety, and post-traumatic stress disorder (PTSD) evaluated using validated psychological instruments. We conducted a cross-sectional analysis of 1,229 participants at 6- and 12-month follow-up assessment using data from five studies from the United States, the United Kingdom, and Australia. Symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS), Depression Anxiety Stress Scales, the Davidson Trauma Scale, Impact of Event Scale (IES), and IES-Revised (IES-R). At 6-month assessment there were moderate to strong correlations of the SF-36 MH scores with HADS depression and anxiety symptoms (r=-0.74 and -0.79) and with IES-R PTSD symptoms (r=-0.60) in the pooled analyses. Using the normalized population mean of 50 on the SF-36 MH domain score as a cut-off, positive predictive values were 16 and 55% for substantial depression; 20 and 68% for substantial anxiety (Depression Anxiety Stress Scales and HADS, respectively); and 40, 44, and 67% for substantial PTSD symptoms (IES-R, IES, and Davidson Trauma Scale, respectively). Negative predictive values were high. The area under the receiver operating characteristics curve of the SF-36 MH score was high for depression, anxiety, and PTSD symptoms (0.88, 0.91, and 0.84, respectively). All results were consistent for the MCS, across the individual studies, and for the 12-month assessment. For researchers interested in general mental health status, the SF-36 MH or MCS offers a strong measure of psychological symptoms prevalent among survivors of acute respiratory failure. For researchers interested in specific conditions, validated psychological instruments should be considered. 
 Question: Symptoms of which disorder are evaluated with the Davidson Trauma Scale?
[EX A]: ptsd

[EX Q]: Context: Sarah Williams (Jennifer Connelly) was a teenager with a large imagination and love for fantasy stories, so much so that she enacted her favorite storybook, the Labyrinth, whenever she could. She happened to have been pretending that she was the heroine in her story while wandering in the park near her house when the clock on the near by city hall building struck, informing her it was 7pm. She realized she was an hour late and needed to get home to watch her baby stepbrother, Toby (Toby Froud). After arguing with her stepmother about her tardiness and feeling ignored by her father, Sarah was left alone with her fussy infant brother. Angered that her stepmother had given her brother one of her favorite teddy bears, a tattered toy called Lancelot, Sarah shouted into the air for someone to take her away from 'this awful place.' To get Toby to stop crying, she told him the story of how the Goblin King was in love with the girl who was 'forced to stay at home with the baby' and that he had 'given her certain powers.' But Sarah in no way believed this story could be real.In anger that the child wouldn't stop crying, Sarah did call for the goblins to take her brother. They took Toby away and Jareth (David Bowie), the King of the Goblins, gave her an option; she could take her dreams or spend 13 hours in his kingdom, an ever-changing maze called the Labyrinth. If she was able to get to the castle at the center within the specified time, her brother would be spared from becoming a goblin. Sarah was resolved to save her brother and the king left her to do her task.She immediately met an ancient looking dwarf with a feisty attitude who showed her how to enter the Labyrinth. His name was Hoggle (voice Brian Henson) and he told her not to take anything for granted in that place; she didn't seem to find him very helpful and basically told him to leave. However, eventually she got herself stuck in an oubliette, and the one sent by the Goblin King to 'rescue' her was Hoggle.But Hoggle was beginning to like Sarah and against the orders he was given to send her back to the beginning of the Labyrinth, having her start all over again, and therefore be late, he made the choice to help her get to the center and reach her brother. This did not bode well with Jareth, who in umbrage at Sarah's haughty attitude took three hours of her time away and threatened to send Hoggle to the most horrible place known in the Labyrinth for his betrayal, a stinky land of slimy mud called the Bog of Eternal Stench. Then Jareth turned to Sarah and asked her how she was enjoying his Labyrinth. When she flippantly said it was a 'piece of cake,' the king sent a machine covered in spinning knives after her and Hoggle, then disappeared. They were able to escape, yet Hoggle got scared by the sound of a howling creature and said he was a friend to no one but himself, leaving Sarah to fend for herself.Sarah forced herself not to be afraid, remembering she had been told 'things aren't always what they seem in this place.' She found Ludo, a giant furry beast and a gentle creature despite his massive size, who became her friend when she saved him from being tortured by a bunch of goblins. But she became separated from Ludo too and found herself in a strange forest where she met the Firies, creatures that were able to dismember themselves and take off their heads. They tried to take off her head, which of course didn't work, but they didn't stop trying to mutilate her, so she threw their heads away. Hoggle came to her rescue, but she didn't know that the Goblin King had threatened that if she ever kissed him, he would immediately be sent to the Bog. As soon as her lips touched the dwarf's bald head in a kiss of gratitude for being rescued, the stones beneath them shook and they fell to the Bog. Thankfully they did
