Factor analysts was used to evaluate the short form of Yalom's Curativ
e Factors Scale with data from 372 participants in the 1986 American G
roup Psychotherapy Association Institute Groups. With the data randoml
y assigned to three subgroups, results showed 10 scale items loading o
n three factors across all three subgroups. When the data was organize
d into two self-selected subgroups corresponding to the two Institute
group categories, factor analyses showed the first factor to be consis
tent with the previous analyses, but other factors showed differences
interpreted to be characteristic of the two groups' modalities. The st
udy suggests a framework for understanding the concept of therapeutic
factors and how they work together.
