The comparison of the behavioral observation system and the brief psychiatric rating scale-expanded.
The construct validity of the Behavioral Observation System (BOS), an observational instrument used by line staff to rate psychopathological behaviors, was studied using comparisons with the Brief Psychiatric Rating Scale-Expanded version (BPRS-E). A sample of 100 inpatient participants was rated using the BPRS-E on the same day they were rated by line staff using the BOS. Pearson product-moment correlations were performed, supporting good convergence and divergence. Principle component analysis on the six BPRS-E scales and the four BOS scales resulted in a three-factor finding. This analysis was supportive of construct validity. Uses of the BOS in light of these findings were discussed.
