question:
Rates of remission were examined in two controlled 12-week studies of sertraline and placebo for post-traumatic stress disorder (PTSD). The performance of three scales was evaluated: the self-rated Davidson Trauma Scale (DTS), and two interviewer scales: the Clinician Administered PTSD Scale (CAPS) and Clinical Global Impressions (CGI). Sertraline proved significantly superior to placebo with respect to remission on all three ratings. Rates of remission were very similar for all scales, ranging from 23.1-26.3% for sertraline and 13.9-14.9% for placebo. Traditional thresholds for the CAPS and DTS were tested relative to the CGI and to each other. The CAPS and DTS thresholds of < 20 and < 18 were found to be valid.
answer:
Symptoms of which disorder are evaluated with the Davidson Trauma Scale?


question:
So that people in developed nations maintain a good lifestyle and people in developing nations have the ability to improve their lifestyles, natural resources must be conserved and protected (Figure 1.1). People are researching ways to find renewable alternatives to non-renewable resources. Here is a checklist of ways to conserve resources: Buy less stuff (use items as long as you can, and ask yourself if you really need something new). Reduce excess packaging (drink tap water instead of water from plastic bottles). Recycle materials such as metal cans, old cell phones, and plastic bottles. Purchase products made from recycled materials. Reduce pollution so that resources are maintained. Prevent soil erosion. Plant new trees to replace those that are cut down. Drive cars less, take public transportation, bicycle, or walk. Conserve energy at home (turn out lights when they are not needed). Click image to the left or use the URL below.
