Warnings about this 300-Item Version of the IPIP-NEO

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.

Best estimates indicate that the 300-item version of the IPIP-NEO produces a report over 99% of the time.

However, network errors, either on your side or with the Penn State network, can prevent the program from proceeding normally.

Spending 30-40 minutes answering 300 questions but getting no feedback can leave you angry and frustrated, so make sure that you have a good network connection before you begin.

If you have problems getting results or prefer to invest less time taking the test, you can take the shorter version.

Although you are not required to answer all of the items, skipping items will lower your scores. In particular, missing responses may lower the 30 facet scores dramatically.

Although people have successfully completed the inventory on phones and tablets, this site is not optimized for smaller screens. It is recommended that you take the inventory with a laptop or desktop computer.

To access the test, you must indicate that you understand that taking the test does not guarantee receiving results.

You indicate this understanding by clicking the checkbox below.

Yes, I understand that responding to all items on this inventory is time consuming and that sometimes technical difficulties 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.

In the Unlikely Event that the Program Does Crash...
A problem with your Internet connection or with Penn State's network is probably at fault. If a crash occurs, results are not saved and you must start the inventory from the beginning. You may follow this link for information about service interruptions at Penn State.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 information on this page. Other persons who may have referred you to this site would prefer that you report technical difficulties to me rather than to them.
Purpose of this On-Line Inventory

The primary purpose of this on line inventory is to educate the public about the five factor 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, and mischievous responding can invalidate the report.

If knowledgeable acquaintances disagree with the test results, then the results are wrong.

Acknowledgment that You Understand the Limitations of the Test Results
Before you can access the test, you must endorse the statement below by clicking the checkbox.

Yes, I understand that the primary purpose of this site is to educate the public about the five factor model 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.
