An investigation of the factor structure of the Psychological Screening Inventory (PSI) was undertaken using a newly developed method of factor analysis to define an oblique simple structure. The two-fold objectives included interest in the factor structure of the PSI and interest in evaluating the utility of the marker variable method of factor analysis. Five factors were defined to yield a good oblique simple structure. The analysis was repeated using different sets of marker variables to verify that the same solution would result.
