16PF & Related Constructed using factor analysis –Different factors for adults and children 16 Primary Scales 5 Second Order Factors One of most used and researched instruments A great deal of validity data
Administration & Scoring 1 hour supervised 6th grade reading level Caution on using “b” 4 published keys (2 can be hand made) Calculation of Secondary Factors (No TV, movies, etc.) This does not seem so bad.

Response Style Scales Impression Management: 95 percentile call Fake Good; 5th percentile call fake bad Infrequency: 95 percentile call invalid –Hand scoring you must make your own key Acquiescence: 95 percentile invalid “true response set”; 5 percentile call invalid “false response set” –Hand scoring you must make your own key
