Description of intervention(s) / exposure
In this randomised controlled trial, four memory rehabilitation programmes will be compared namely 1) self-awareness training plus compensatory training, 2) self-awareness training plus remedial training, 3) placebo plus compensatory training, and 4) placebo plus remedial training. A pretest/post-test/follow-up independent-groups design will be used to compare the relative effectiveness of compensatory versus remedial rehabilitation and self-awareness training. Participants will be randomly assigned to the 4 programmes giving 25 participants in each group. Participants will have a 4-week pre-intervention period, then participate in an individual rehabilitation programme for 8 weeks (2 weeks self-awareness training or placebo plus 6 weeks compensatory or remedial training). This will enable the effects of the two components (i.e. remedial versus compensatory training and self-awareness training versus placebo) to be evaluated separately.

Outcomes
Primary outcome [1] 1297 0
To provide a comprehensive assessment of prospective memory three types of evaluation using a) psychometric testing
Timepoint [1] 1297 0
Following the 4-week baseline period, participants will be assessed on all measures by a researcher who is blind to group membership. Participants will then commence one of the 8-week standardised individual rehabilitation programmes. All programmes will be administered by the same trained researcher according to standardised, written week-by-week procedures. Post-intervention assessment using all measures will occur at the end of the programme and at a follow-up appointment arranged 6 months later.
Primary outcome [2] 1298 0
To provide a comprehensive assessment of prospective memory three types of evaluation using b) self-report and relative's report of prospective memory function
Timepoint [2] 1298 0
Following the 4-week baseline period, participants will be assessed on all measures by a researcher who is blind to group membership. Participants will then commence one of the 8-week standardised individual rehabilitation programmes. All programmes will be administered by the same trained researcher according to standardised, written week-by-week procedures. Post-intervention assessment using all measures will occur at the end of the programme and at a follow-up appointment arranged 6 months later.
Primary outcome [3] 1299 0
To provide a comprehensive assessment of prospective memory three types of evaluation using c) assessment of diary use (number and quality of diary entries)
Timepoint [3] 1299 0
Following the 4-week baseline period, participants will be assessed on all measures by a researcher who is blind to group membership. Participants will then commence one of the 8-week standardised individual rehabilitation programmes. All programmes will be administered by the same trained researcher according to standardised, written week-by-week procedures. Post-intervention assessment using all measures will occur at the end of the programme and at a follow-up appointment arranged 6 months later.
Secondary outcome [1] 2325 0
The effect of participation in each of the four prospective memory rehabilitation programmes on community integration will also be assessed using a psychosocial reintegration scale.
Timepoint [1] 2325 0
At pre-assessment, post-assessment and 6-month follow-up assessment by a researcher blind to group membership.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
One-sided numbered cards were randomly selected with sequence concealed until interventions were assigned.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Restricted randomisation was used with blocking method. Participants were randomly allocated to one of four intervention groups through selection of one-sided numbered cards such that no group will have n + 1 participants until all other groups have n.
Masking / blinding
Blinded (masking used)
