“…The 16 tools assessed properties such as internal consistency (15 tools) [28–31, 33–35, 37–44], content validity (10 tools) [28–31, 33, 34, 37–39, 42], construct validity (hypothesis testing) (7 tools) [30, 31, 34, 38, 40, 41, 43], reliability (8 tools) [28, 30, 31, 33, 35, 39, 42, 43], structural validity/factor analysis (6 tools) [34, 37, 40–42, 44], criterion validity (2 tools) [30, 38], responsiveness (sensitivity to change) (3 tools) [28, 31, 38] and cultural validity (1 tool) [32]. The methodological quality of included studies ranged mostly from “poor” to “good” ( n = 11) except that 5 studies addressing content validity [30, 31, 33, 38, 39], and 1 study [39] addressing internal consistency and structural validity demonstrated “excellent” quality.…”
