IPIP-NEO Personality Inventory, 120-item Version

This on-line personality inventory is not optimized for tablets or phones. A device with a full-sized screen is not necessary, but recommended.

When you finish the inventory and your narrative report is displayed, YOU are responsible for saving the report before you leave that Web page, using the instructions at the top of the report. Individual reports are NOT saved by the system, so if you close the report Web page, you will not be able to return to your report.

Purpose and Limitations of the IPIP-NEO On-Line Personality Inventory

The primary purpose of this on-line inventory is to educate the public about the five major personality domains, alternatively called the Five-Factor Model (FFM) or Big 5 (B5) model of personality..
More specifically, the report explains the likely consequences of one's standing on five broad personality domains.
These broad domains cover normal differences in personality that should be obvious to people who know you well.
Secondarily, this inventory estimates your standing on the 5 broad domains and 30 subdomains of personality.
The inventory does not reveal hidden, secret information about you nor does it assess serious psychological disorders.
The report is designed to be objective, not pleasing or flattering.
Measurement error, misunderstandings, carelessness, too many missing responses, and mischievous responding can invalidate the report.
If knowledgeable acquaintances disagree with the test results, they are most likely correct and the test results are wrong.
On rare occasions, responding to all of the items will fail to produce a report. In such cases a problem with your Internet connection or with the server for this site is probably at fault. If a crash occurs, results are not saved and you must start the inventory from the beginning. Your best bet for completing the inventory is to simply wait an hour or two and try again. You may want to use a different machine and/or Internet connection. If you experience any technical difficulties (items fail to appear on the screen, test does not advance to next page, Web browser freezes, no narrative report is displayed, etc.) you may send an email describing the problem to me at j5j@psu.edu, although it is unlikely that I can provide help beyond the suggestions in this paragraph.

Acknowledgment that You Understand the Purpose and Limitations of the Test Results

Before you can access the test, you must endorse the statement below by clicking the checkbox.

I understand that the primary purpose of this site is to educate the public about the five major domains of personality, and only secondarily, to estimate the respondent's standing within the five factor model. I understand that the program that generates the report is designed to produce estimates that are as accurate as possible, but that measurement error or improper responding can produce inaccurate results. If I think I have answered the items honestly and carefully but my results are inaccurate or not as pleasing as I would like them to be, I will have knowledgeable acquaintances evaluate the validity of the report before contacting Dr. Johnson. If I choose to critique the test or narrative report after receiving feedback from knowledgeable acquaintances, I will do so in a courteous and civil manner.

I also understand that responding to all items on this inventory is time consuming and that technical difficulties may prevent the results from being displayed. I am responding to this inventory with the full knowledge of the risk that I might not receive results. I accept full responsibility and risk for the time I invest in responding to this inventory.

The IPIP-NEO is not equivalent to the commercial inventory on which it is based, the NEO PI-R™, authored by Paul T. Costa, Jr. and Robert R. McCrae. The genuine NEO PI-R™ (240 items) is considered by many psychologists to be the best inventory for measuring traits within the Five Factor Model (FFM) of personality. The NEO PI-R™ is copyrighted by Psychological Assessment Resources (PAR) in Florida, and can only be ordered by professionals and used by permission. You can contact PAR at: 1-800-331-TEST, or http://www.parinc.com.
The development and validation of the IPIP-NEO is described in the following publication:

The scoring and narrative report routines for these items were created by Dr. John A. Johnson, Professor Emeritus of Psychology, Penn State University.
Any programmer who wishes to examine the Perl CGI scripts underlying this inventory, or anyone with further questions may contact John A. Johnson at j5j@psu.edu.
