title: A factor analytic and psychometric examination of pathology of separation-individuation.
abstract: Two studies are described that attempt to determine if standard-scale-reduction techniques could yield a construct-valid diagnostic screen of pathology of separation-individuation for use in nonclinical university settings. In Study 1 (N = 210), a measure of pathology of separation-individuation (PATHSEP) was reduced successfully to a single, internally consistent factor, accounting for 36% of the variance. In Study 2 (N = 304), these items also coalesced around a single factor, accounting for 35% of the variance. Study 2 also showed that PATHSEP is correlated moderately and positively with indices of insecure attachment, with the Center for Epidemiological Studies-Depression Scale, and with indices of psychiatric symptomatology (Hopkins Symptom Checklist). PATHSEP also was associated with a poorer profile of adjustment to college. Males reported more pathology of separation-individuation than did females. Evidence supports the construct validity of a shortened version of PATHSEP. Directions for future research are noted.
