TOPICS is a collation of validated instruments measuring physiological, psychological and social health and wellbeing. Longitudinal research projects submitted at least one wave of follow-up data, typically 12 months after baseline data collection. However, please note that the time duration between baseline and follow-up may vary between individual studies. A data dictionary and syntax for additional derived variables are available (see section codebooks and spss syntax). Participants refer to older persons who completed the questionnaire; caregivers refer to participants who were providing informal care for an older person.
