Construct validity of the 31-item Likert scale was supported by an overall Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy (MSA) value of 0.853 (range 0.766 to 0.902), along with a highly significant Bartlett’s Test of Sphericity (P < 0.0001), indicating that the data were suitable for factor analysis ( Table 3 ).
