Q: 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.

Q: The influence of America is increasing in my country. Spanish people drink Coca Cola, wear blue jeans, watch Hollywood movies, listen to American music, and eat fast food, and they do these things every day. I think that American movies are a good way to spread American culture because people are often influenced by what they see in the movies. Most of the programs and documentaries we watch on TV are from America, and most of the movies we go to see are made in Hollywood. In the last few years, the government has tried to protect the Spanish movies. Now, in our cinemas, at least twenty percent of the movies which are shown must be from Spain or from other countries in Europe. American culture is a part of Spanish life now. It's certain that many things from America are as much a part of people's lives as Spanish things. For example, Coca Cola is as familiar to everybody as any typical Spanish product. I've known about Coca Cola for my whole life. However, it's different with Western fast food. For example, I don't think McDonald's is as successful in Spain as it is in other countries. In my opinion, one of the reasons may be the lifestyle of the Spanish people. The Spanish people normally eat at home. On the other hand, maybe McDonald's hamburgers will eventually replace the famous Spanish tapas. It's true that in every city in Spain you can find a McDonald's, and it is more popular among the Spanish children than among the adults. In any case, it's obvious that American culture is becoming more and more a part of our lives every day.

A:
What plays an important part in the spreading of American culture in Spain?
