Girls' anxiety levels were assessed using the self-report Multidimensional Anxiety Scale for Children (MASC; March et al., 1997). The MASC consists of 39 items assessing four subscales: physical symptoms (α = .80), social anxiety (α = .86), separation anxiety (α = .77), and harm avoidance (α = .69). The MASC has been found in previous studies to have acceptable validity and reliability (March et al., 1997).
