At least two prior studies have indicated that school absenteeism
might be a significant problem for patients with
JPFS. Reid, Lang, & McGrath (1997) found that adolescents
with JPFS missed an average of 22.6 (SD¼16.63)
days of school in an academic year and Kashikar-Zuck,
Vaught, Goldschneider, Graham, & Miller (2002) found
that adolescents with JPFS reported missing 5.23 days
(SD¼7.76; range¼0-–30) in the last 30 days of school.
