SCQIn each Wave of the TILDA study, once the participants have finished the face-to-face interview, the interviewer leaves the participant a short questionnaire, which should take about 15 minutes to complete. Participants can fill out the questionnaire in their own time and have the interviewer come back and collect it, or it can be posted back to us in the stamped addressed envelope it comes with.


The self-completion questionnaire includes questions about the following aspects of participants’ lives:

  • Quality of life
  • Personality and values
  • Social activities and hobbies
  • Quality of relationships
  • Attitudes towards ageing
  • Accommodation and local area
