The Profile of Mood States (POMS) is an instrument composed of six mood scales that were developed using clinical populations.
This study examines the replicability of the POMS factor structure in lead-smelter workers and its association with demographic variables and lead exposure.
Four hundred sixty-seven current and retired smelter workers completed the POMS, and a factor analysis was performed on the individual items.
Two multiple regressions in the currently employed workers (n=340) with a mean age of 40 years (range, 20-63 years) were used to compare the relationship of the resulting POMS factors with demographic characteristics and two measures of occupational lead exposure : current blood lead level (mean, 28 mug/dL ; range, 4-62 mug/dL) and working-lifetime integrated blood lead level (mean, 711 mug-yr/dL ; range, 1-1537 mug-yr/dL).
Factor analysis produced one factor, labeled « general distress », that was composed mainly of items from five of the six POMS subscales (anger, confusion, depression, fatigue, and tension) and a second factor labeled « psychological adjustment ».
Demographic variables, including education, age, and alcohol use, were significantly related to the « general distress » factor score.
After the effects of the demographic variables were accounted for, the « general distress » factor was significantly related to integrated blood lead level but not current blood lead level. (...)
