The multi-purposed instrument, 16PF or 16 Personality Factors, is used as a career evaluation tool, for couples counseling and personality assessment. 16 PF is used by psychologists and counselors to provide job occupations that best fit the individuals’ characteristics. Also, 16PF can identify such problems as anxiety, behavioral adjustment, academic, emotional, and social.
When taking the test, the participant must answer 185 multiple-choice items along with 26 multiple-choice items for the Couples Counseling Report. Approximately 35-50 minutes is necessary for completion. The 16PF Fifth Edition is the current version of the test.

Reliability and Validity
Moderate to good reliability rating have been reported for the 16PF. Based on a sample of 10,261 individuals, Internal consistency reliabilities are on average 0.76 for the primary scales and a range of 0.68 to 0.87 for all 16 scales. The test-reliabilities over a 2 week period showed scores of 0.69-0.87 for all scales and a 2-month interval showed scores ranging from 0.56-0.79. This data can be found and supported in the 16PF Fifth Edition Technical Manual by Conn & Rieke, 1994.
Studies conducted have supported construct validity (Chernysheno, Stark, & Chan, 2001; Conn &Rieke, 1994; Catell & Krug, 1986; Gerbing & Tuley, 1991; Hofer, Horn, & Eber, 1997). Translation into several languages – Italian, French, Japanese, German – are available for the 16PF. The test’s applied validity to counseling, career development, personality assessment and clinical problems has been supported (Kelly, 1999; Krug & Johns, 1990; Schuerger & Watterson, 1998). The 16PF is an established instrument receiving thousands of publications and qualified recommendations.
