Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The aim of these studies is to adapt the self-affirmation kindness questionnaire for use in a mobile application. Two studies will be conducted to test hypotheses that simplifying and shortening the original questionnaire in systematic ways will result in comparable effectiveness (compared to the original version) in promoting reduced defensive avoidance, less reactance, greater yielding, and higher intentions to quit smoking among a sample of smokers.
