Relationships Between Smoking Status and Psychological Distress, Optimism, and Health Environment Perceptions at Time of Diagnosis of Actual or Suspected Lung Cancer.

The study included only 52 patients from two Midwestern sites, and the sample was mostly White and male, so results may not apply to more diverse groups. The small number of never smokers reduced the chance of detecting real differences. It was a one-time survey, so it cannot show whether smoking status caused distress, distress caused smoking, or both were affected by diagnosis. Smoking status was self-reported without biochemical testing, so some current smokers may have been misclassified. The study did not measure anxiety sensitivity, a possible marker of emotional vulnerability in smokers. Many differences were trends only, and most were not statistically significant. At the time of the survey, 44% had only suspicious findings rather than a confirmed cancer diagnosis, so the group mixed suspected and confirmed cases.

Do not conclude that quitting smoking lowers distress or that distress causes continued smoking. This was a one-time survey of 52 patients, and most differences between smoking groups were not statistically significant.
