  1. a Prevalence ratios in bold style are statistically significant on 95% confidence level.
  2. b Answers only from those reporting intrusive thoughts (positive or negative) are indicated.
  3. c Waking up with discomfort or anxiety at least once a week or more frequently in the last month. Depressive mood is the highest four (2–6) on a scale of six. Low to moderate self-assessed quality of life is the lowest four (0–4) on a scale of six. All measures are within the time frame “during the past month”.
