Methods | RCT. | |
Participants | 24 participants with dementia as assessed by DSM‐IV recruited from care homes in North Wales, UK. Mean age: 86 years. |
|
Interventions | Intervention: individual life review/life story book (participants were involved in the creation). Control: life story book given to participants as a gift 12 weeks into the intervention (just after post‐treatment assessment). |
|
Outcomes | Quality of life: QoL‐AD. Cognitive: AMI‐E. Mood‐related outcomes: GDS. Carer: QCPR. |
|
Length and frequency of intervention | 1 hour per week for 12 weeks. Mean of 12 sessions (range 11‐16). | |
Time points measured | Baseline (T0), 12 weeks' postbaseline (T2) and 6 weeks later (T3). (T3 data not included in this review*). |
|
Number of participants who did not complete study | 1/24 (4.17%). | |
Notes | *Data from T3 not included in the current review as participants in the control condition were given life story books and used them between T2 and T3. Once they received their books, the control condition was no longer treatment as usual or passive. | |
Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | Participants were allocated using a sequential individual‐based randomisation, which randomised participants into parallel groups using a dynamic stratification algorithm. The randomisation process was carried out by an accredited clinical trials unit. |
Allocation concealment (selection bias) | Low risk | Randomisation process was undertaken by an accredited trials unit. |
Blinding of outcome assessment (detection bias) All outcomes | Low risk | Outcome measures carried out by 2 assessors blinded to treatment allocation with no other involvement in the process of the research. |
Incomplete outcome data (attrition bias) All outcomes | Low risk | 1 participant died part way through the trial, their data were excluded. |
Selective reporting (reporting bias) | Low risk | All outcomes listed in the methods section were reported and there was no evidence of selective outcome reporting. |
Other bias | Low risk | n/a. |
Availability of training and supervision Objective outcome measures | Low risk | Therapist was a clinical psychologist trained in reminiscence work. Weekly supervision was provided with consultant clinical psychologist. |
Availability of manual or protocol for intervention All outcomes | Low risk | Life review intervention was based on Haight's Life Review model and Life Review Experiencing Form (Haight 1992). |
