DANISH. Ph.D. Fellow Peter Hartmann, in conjunction with the Individual Differences Research Unit from the Institute of Psychology at the University of Aarhus, has developed a personality inventory called the Danish International Personality Item Pool Questionnaire (D-IPIP-Q), based on the 300 item on-line IPIP-NEO inventory administered by John A.

The D-IPIP-Q also includes six additional items to measure Social Desirability and Carelessness response biases. The test reliably measures five personality factors and has been normed on 200 young adults. For further information, contact the author at:

ESTONIAN. René Mőttus, Helle Pullmann, Jüri Allik, Liina Haring, Kenn Konstabel, and Anu Realo from the University of Tartu in Estonia, translated the IPIP scales measuring constructs similar to the 30 facets of the NEO-PI-R into Estonian.

Therefore the revised adaptation includes some new Estonian items. Also, they reduced the number of items from 10 to 8 per facet scale. Mőttus and his colleagues compared the adapted scales with those of the Estonian version of the NEO-PI-R, which was administered in parallel with the IPIP scales. In addition, they investigated the external validity of the scales, as well as cross-observer agreement. For further information, contact:

POLISH. Prof. Maria Pachalska from the Institute of Psychology, University of Gdansk, Gdansk, Poland, President of the Polish Neuropsychological Society, has translated the IPIP 50-item Big-Five markers into Polish.

The Polish inventory is now available in both a first person version, to be completed by the patient, and a third-person version (for completion by significant others, due to obvious problems in comprehension in these populations). The discrepancies between these versions for the same patient is an area of particular interest. Research is also now underway to look for possible relations between IPIP items and measures derived from the Quality of Life after Brain Injury (QOLIBRI) pan-European project. Prof. Pachalska would like to collaborate with others interested in these aspects of personality research. For further information, contact her at:

THAI. Panida Yomaboot and Dr. Andrew J. Cooper have translated , back-translated, and factor-analyzed the 50 items representing the NEO domains into the Thai language. The work, which was conducted as a part of a PhD programme at Goldsmiths, University of London, has been published in the Journal of Somdet Chaopraya Institute of Psychiatry Vol.10, No.2, September 2016 (Thailand).

TURKISH. Prof. Oya Somer and her colleagues Mediha Korkmaz and Arkun Tatar in the Psychology Department at Ege University in Izmir, Turkey, have translated 924 IPIP items into Turkish. They have used these items to develop a new Turkish personality inventory, which includes 220 items, measuring 17 lower-level scales and five higher-level constructs. The standardization sample included 1,675 Turkish adults (805 male, 845 female) and 1,828 Turkish students (891 male, 937 female). The development of the scales was based on item factor analyses and internal-consistency procedures. Findings from reliability and validity analyses are available from Prof. Somer at:

URDU. The 10 IPIP items in the NEO Conscientiousness domain scale in the Big Five factor structure have been translated into Urdu by Qurat-ul-ain and Hina Noreen for their ​research on social dominance orientation, conscientiousness, and corruptive tendencies in government employees, under the supervision of Prof. Dr. Rukhsana Kausar (Director, Institute of Applied Psychology, University of the Punjab, Lahore, Pakistan).  T​he Urdu version of the scale is available from

URDU. Shagufta Perveen, in consultation with a panel of language experts, has translated, back-translated, and adapted the items included in the IPIP inventory measuring constructs similar to those in the NEO-PI-R into standard Urdu. Perveen is a doctoral candidate at Hazara University in Pakistan, under the mentorship of Dr. Syeda Farhana Kazmi. Both are interested in the assessment of the interactions between Madrassah education and personality dynamics in Pakistan. The contact address is:

VIETNAMESE. April Leininger, a psychological anthropologist, has created a Vietnamese-language personality inventory by translating and back-translating the IPIP items corresponding to the NEO-PI-R. She administered this measure to Vietnamese Americans along with a Vietnamese-language inventory of cultural values. The Vietnamese items can be obtained by contacting her at:

VIETNAMESE. Dr. Kate E. Walton, Associate Professor of Psychology at St. John's University in New York, has translated into Vietnamese (and back-translated) all of the IPIP items included in the 45 bipolar scales measuring the AB5C constructs. The objective of her research is to study normal and abnormal personality development longitudinally in a diverse sample of Vietnamese. Study participants include a combined sample of more than 500 people recruited at a university in Hanoi as well as a community sample recruited from a rural village outside of Hanoi. A subset of these participants was assessed at two time points. To learn more about this project, contact Dr. Walton at:

WELSH. Gareth Hagger-Johnson at the University of Edinburgh in Scotland and Soracha Cashman at the University of Wales in Bangor (Wales) have developed Welsh translations of the 100 items included in the IPIP Big-Five factor markers. The Welsh items can be obtained from:
