Feasibility and utility of PedsQL SF15 for children initially S. haematobium egg-positive or egg-negativea.

aCases were those children initially found to have S. haematobium eggs on urine filtration during parasitological surveys. Controls were children who had been egg-negative. N.B. The PedsQL SF15 was administered 3–16 months after completion of testing and treatment for infection.b% Floor/Ceiling = the percentage of scores at the extremes of the scaling range. Floor or ceiling effects in the range of 1–15% are acceptable while those >15% [in BOLD] are considered to provide less precise estimates.
