“…Included studies employed different measures to determine performance changes including the Canadian Occupational Performance Measure (COPM) and the Goal Attainment Scale (GAS), the Performance Quality Rating Scale (PQRS), and the Activity Scale for Kids (ASK). The COPM was used in five of them (Cameron et al, 2017;Ghorbani et al, 2017;Jackman et al, 2018aJackman et al, , 2018bSousa et al, 2020); three studies used the GAS (Ghorbani et al, 2017;Jackman et al, 2018aJackman et al, , 2018b; four studies used the PQRS (Cameron et al, 2017;Gimeno et al, 2019Gimeno et al, , 2021Sousa et al, 2020); and one study used ASK (Cameron et al, 2017). A good inter-rater reliability and the construct/criterion validity of COPM have been described for children with CP (Verkerk et al, 2006).…”
