It was a revolutionary concept measuring the whole of human personality using structure discovered through factor analysis. It was First published in 1949, the 16PF Questionnaire has had four major revisions, in 1956, 1962, 1968, and the fifth edition in 1993. The latest edition contains 185 multiple-choice items, with a three point answer format. Item content is non-threatening, asking about daily behavior, interests, and opinions. The short ability scale items (Factor B) are grouped together at the end of the questionnaire with separate instructions.
A subject’s raw score for each of the 16 primary factors is obtained through a weighted procedure where particular responses count as “1” or “2” summative toward the final raw score. These weighted or unweighted sums are then compared to the desired normative score tables in the tabular supplement where a particular sten score is identified based on the magnitudinal range of the response and the individual normative demographics of the respondent. This sten score is entered on the profile form and subsequently depicted graphically for ease of interpretation.
|Reliability and Validity||
For the 16PF primary scales, test–retest reliabilities average 0.80 over a two-week interval (ranging from 0.69 to 0.87), and 0.70 over a two-month interval (ranging from 0.56 to 0.79). Internal consistency estimates for the 16PF primary scales on a diverse sample of 4,660, range from 0.66 to 0.86, with a mean of 0.75 (Conn and Rieke, 1994).
The norms were constructed for high-school juniors and seniors, college students, and a general nation-wide population of age and income levels commensurate with the then current U.S. Bureau of Census figures.
The 16PF Questionnaire can be used in a wide range of settings, including industrial/organizational, counseling and clinical, basic research, educational, and medical settings.
