5. 16PF & Related Constructed using factor analysis 16 Primary Scales
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

6. 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.

7. Stability of Primary Scales

Only 1 scale under .75 (B) at 2 weeks.

8. Stability of Secondary Scales

10. 16PF Uses Sten Scores Mean is 5.5 and the standard deviation is 2
Sten 3 is the 11 percentile & 8 the 89 percentile
Sten 2 is the 4 percentile and 9 the 96 percentile
1 is the 1 percentile and 10 the 99 percentile
I think I am Numbered out!

Extreme Scale for Broad Factors (1, 2, 3 and 8, 9, 10)
Extreme Scales Primary Factors (1, 2, 3 and 8, 9, 10)
