Assessing frontal lobe behavioral syndromes with the Frontal Lobe Personality Scale

Reliability and construct validity are reported for the Frontal Lobe Person ality Scale (FLOPS), a brief neurobehavior rating scale. The FLOPS Family f orm was completed by family members of 24 frontal lobe brain-damaged patien ts, 15 non-frontal lobe brain-damaged patients, and 48 healthy controls. In trascale reliability was demonstrated (internal consistency .96; split half .93). Validity studies of frontal lobe patients post-lesion compared to th eir pre-lesion status, to healthy controls, and of frontal lobe patients pr e-and post-lesion compared to non-frontal lobe patients pre- and post-lesio n, indicated that frontal lobe patients post-lesion showed significantly mo re "frontal" behavior than (a) pre-lesion frontal lobe patients, (b) health y controls, and (c) post-lesion non-frontal lobe patients. The FLOPS appear s to be useful for quantifying frontal lobe behavior in clinical and resear ch settings.
