Inclusion and exclusion criteria used in the systematic review. The criteria were based on the PICO framework: Patient problem –dementia; Intervention –Creative Visual art; Comparison/Control –participants with no dementia, formal or informal carers, family members; Outcome measures - cognitive function, biological and psychological symptoms of dementia, Wellbeing and Quality of life. We made the difference between pilot and feasibility studies according to Whitehead et al (2014) definition [16]: ‘feasibility’ should be used as an overarching term for preliminary studies and the term ‘pilot’ refers to a specific type of study which resembles the intended trial in aspects such as having a control group and randomization; studies labelled ‘pilot’ should have different aims and objectives to main trials and should also include an intention for future work [16]
