The present study examined the role of acculturation in
manifestation of depressive symptoms among 230 Korean American
older adults (Mage=69.8, SD=7.05) in Florida. Given the cultural
emphasis on modesty and self-effacement in the traditional Korean
society, we hypothesized that older Korean Americans who were
less acculturated to American culture, when compared to the more
acculturated ones, would be more likely to inhibit positive affects
in depressive symptom reports. Using two validated measures of
depressive symptoms, the short forms of the Geriatric Depression
Scale (GDS-SF) and the Center for Epidemiologic Studies-
Depression Scale (CES-D), different response patterns for low and
high acculturation groups were identified. First, there was low
comparability in the factor structures for both the GDS-SF and the
CES-D across low and high acculturation groups. A differential
item function analysis based on partial correlations indicated that
older adults in the low acculturation group inhibited endorsing
positive affect items; one item in the GDS-SF (#7 feel happy) and
two items in the CES-D (#5 felt hopeful and #8 was happy). The
finding suggests the substantial cultural influences in expressing
emotions, especially those related to positive affects. Implications
are discussed from a cultural perspective.
