Description of the Test:

The 16PF5 is the fifth version of the 16PF, a self-report questionnaire originally devised by Dr Raymond Cattell as part of his work to identify the primary components of personality. His research, which began in the 1940s, was based on the use of factor analysis to interpret data derived from questionnaire items (Q-data) and from behaviour ratings (L-data). The 16PF was designed to give a broad measure of personality that would be useful to practitioners in a wide range of settings: from selection, to counselling to clinical decision-making. The 16PF5 was constructed by IPAT in the USA, who also collected US normative data on a sample of 2500 persons. The American 16PF5 was Anglicised by ASE, changing 36 items. UK normative data have been collected by ASE on a sample of 1322 persons. The 16PF5 is designed for use with adults, defined as those of 16 years and above. Unlike previous versions there is now only one form of the questionnaire. The 16PF5 has 185 items, and measures 16 personality factors known as the primary factors. One of the 16 factors is Reasoning. Most items use a True/?/False format, but some offer choices between more elaborated answers. The B (Reasoning) factor uses conventional multiple-choice Reasoning test items, with three choices. These are grouped at the end of the question booklet, so they can be omitted if desired. The 16PF5 has a separate reuseable question book, and a self-scoring answer sheet with a carbon insert. The authors say that the 16PF5 continues to measure the same 16 primary personality factors as version 4. They are bipolar measures that are identified by an alphabetical system and a factor title, which reflects the high end of each scale. These are: A Warmth M Abstractedness B Reasoning N Privateness C Emotional Stability O Apprehension E Dominance Q1 Openness to Change F Liveliness Q2 Self-Reliance G Rule-Consciousness Q3 Perfectionism H Social Boldness Q4 Tension I Sensitivity IM Impression Management L Vigilance Second-order or global factors have been derived from factor analysis of the 16 primary factors. The global factor title describes the high end of a scale. The five global factors are: Extraversion, Anxiety, Tough-Mindedness, Independence and Self-Control. Two additional response style measures are available, an Infrequency Scale which indicates whether the candidate answered a relatively large number of items in a way different from most people and an Acquiescence scale which measures the tendency to answer ‘true’ to an item regardless of its content. Both of these scales as reported in the administrator’s manual were devised from use of the US edition with US samples.
