Only one study demonstrated test–retest reliability (r = 0·95). Three studies internal consistency, with Cronbach α ranging 0·85 0·90. Fifteen showed sensitivity change scores, significant differences baseline end study. Twenty-six correlated other objective subjective instruments demonstrate construct (convergent) validity. Seventeen validated translations have been used different countries (including two multinational studies). Nine assessed effectiveness five topical drugs probiotic supplement.
