Factor and cluster analyses with the Rosenzweig Picture Frustration Study.
The Rosenzweig Picture Frustration (P-F) Study data of 104 psychiatric hospital patients, 56 males and 48 females, were subjected first to a Factor Analysis and then to a Cluster Analysis. In the former, five factors were extracted which showed some similarity to other Factor Analyses reported in the literature. The Cluster Analysis turned up one very large group (42% of the sample) characterized by depression and P-F profiles with elevated i and very low E scores. Seven other clusters are described in the article. The factors and clusters found are clinically meaningful and can provide assistance in interpreting P-F profiles. Recommendations for a revised P-F manual to enhance the usefulness of the test are made.
