A fourteen-year study of American Legionnaires who served in the Vietnam War found that which factor was linked to a lower likelihood of posttraumatic stress disorder?
AA shorter tour of duty in the combat zone
BGreater perceived social support at home
CBeing older than thirty at the time of combat
DHaving no previous exposure to firearms
Answer & Solution
Correct answer: B. Greater perceived social support at home
1. Social support means the comfort, advice and assistance received from relatives, friends and neighbours.
2. Those who perceived less support when they came home were more likely to develop the disorder than those who perceived more.
3. Those who became involved in their community were also less likely to develop it and more likely to remit.
4. Age, tour length and prior firearm exposure were not the factors this study followed.
