Validation evidence is provided for scales that measure five aspects of aff
ective well-being in relation to the work context: anxiety-comfort, depress
ion-pleasure. bored-enthusiastic, tiredness-vigour and angry-placid. Confir
matory factor analysis is used to test four alternative structures for the
items in the scales in two samples (n = 871,n = 1915). Analyses in both sam
ples support one structure. The final scales have acceptable internal relia
bility The unique explanatory power of each scale is suggested by partial c
orrelations with theoretically related variables. Confirmatory factor analy
sis indicates that the five factor solution has a better fit with the data
than other first order solutions with fewer factors. Second order factor an
alysis shows that two superordinate factors, corresponding to negative and
positive affect, can account for the relationships amongst the five first o
rder factors.
