Plain English Summary
Background and study aims
Prospective memory (PM) is a form of memory which involved remembering to perform intended actions in the future, simply, remembering to remember. It is an important function and is necessary in order for people to be able to live independently and be self-sufficient. Examples of prospective memory include: remembering to take medicine at night before going to bed, or remembering to go to an appointment. PM can be divided into three types; time-based, event-based, and activity-based. Time-based PM involves remembering to perform an action at a specific time or after a period of time. Event-based PM involves remembering to perform an intention when a cue (reminder) appears. Activity-based PM involves remembering to perform an intention upon the completion of an activity. Maintaining PM is very important for the elderly to be able to live independently. Forgetting things that they need to remember can be upsetting for some older adults, leading to mental health problems such as anxiety and depression. The aim of this study is to find out whether a short program designed to help exercise PM functions can lead to improvements in PM and mood in older adults.
Who can participate?
Adults aged 60 and over who are educated to at least secondary education level
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group take part in a program designed to improve their prospective memory. This involves taking part in one two-hour session each week for a total of six weeks, where participants play a computerised board game designed to exercise their prospective memory as well as taking part in a memory strategy training. Those in the second group receive no extra training and continue as normal for the duration of the study. At the start of the study and then again after six and ten weeks, participants in both groups undergo a number of assessments to assess their prospective memory and mental wellbeing.
What are the possible benefits and risks of participating?
Participants may benefit from improvements to their prospective memory and mental wellbeing. There are no notable risks involved with participating in this study.

Participants will be randomly assigned to the intervention or control groups (1:1) in site-specific blocks that vary randomly in size to ensure adequate randomization, developed by http://www.randomization.net. The randomization sequence will be concealed from research staff.
Intervention group: Participants take part in a 12 hour intervention regarding exercising their prospective memory. This involves one two-hour session per week for six weeks, and involves a process-based intervention component (a computerized board game to exercise prospective memory - VIRTUAL WEEK board game) and a strategy-based intervention component (memory strategy training such as; intention implementation intentions).
Control group: Participants receive no additional treatment and continue as normal for the duration of the study.
Follow up takes place after six week, one month later (10 weeks) and three months later (14 weeks) and involves prospective memory, depression, anxiety and instrumental daily living activities assessments.
Primary outcome measure
Prospective memory (PM) functions are assessed at baseline, 6, 10 and 14 weeks using:
1. PM functions (time-, event-, and activity-based PM) are assessed using a computer-based test
2. PRMQ (a paper-pencil questionnaire) to be used as a subjective measure for PM functions
Secondary outcome measures
1. Instrumental daily living activities are measured using the Instrumental Activities of Daily Living Scale at baseline, 6, 10 and 14 weeks
2. Depression is measured using the Geriatric Depression Scale (GDS) at baseline, 6, 10 and 14 weeks
3. Anxiety is measured using the Geriatric Depression Scale (GDS) at baseline, 6, 10 and 14 weeks
