Second, severe homesickness is associated with significant distress and impairment. There is evidence that homesick persons are present with non-traumatic physical ailments significantly more than their non-homesick peers. Homesick boys and girls complain about somatic problems and exhibit more internalising and externalising behaviours problems than their non-homesick peers. First-year college students are three times more likely to drop out of school than their non-homesick peers. Other data have pointed to concentration and academic problems in homesick students. And maladjustment to separation from home has been documented in hospitalized young people and is generally associated with slower recovery. See Thurber & Walton (2012) for a review.
