In this study, the
Organic Chemistry Anxiety Scale (O-CAS)
consisting of 24 items was developed, its
validity and reliability was analysed. All
the items are positively worded to indicate
increased anxiety. Factor analytic evidence
from a sample (n=340) of university
organic chemistry students indicated that
the O-CAS measured three constructs.
Additional analysis with a second sample
(n=297) showed that scores on these
anxiety constructs were internally consistent,
