Data Collection Event

SydneyMAS - Wave 5

Participants were assessed over the phone only. The medical history interview included questions about depression and anxiety, subjective cognitive decline, self-ratings of activities of daily living (e.g., feeding oneself) instrumental activities of daily living (e.g., driving), and current medications. Also, each participant's informant completed a phone interview and additional questionnaires as part of the caregiver component of the study. The questionnaires were related to quality of life, disability, psychological distress, and the participants’ medical history. An abbreviated neuropsychological l battery test was administered to assess various cognitive domains essential for the diagnosis of dementia and predementia syndromes. The test covered attention/processing speed, memory, language, and executive function.
