Introduction
Apart from the many normal personality traits, some traits are unpleasant for others. There are three overlapping types of dark personality traits known as the dark triad.
The triad (i.e., group of three) consists of machivellianism, psychopathy, and narcissism.
-
Key aspects of machivellianism
-
Manipulativeness
-
Callous affect
-
Strategic-calculating orientation
-
-
Key aspects of psychopathy
-
Deficits in affect (i.e., callousness)
-
Deficits in self-control (i.e., impulsivity)
-
-
Key aspects of narcissism
-
never-ending quest for ego-reinforcement
-
grandiosity

Professor Paulhus is well know for his research on this topic and he is the senior author on the article that describes the short dark triad scale described on this PsyToolkit webpage.

If you want to know more, I highly recommend to watch the above video and read the paper in the references.
One of the problems, in general, with personality scales is that they can be quite long, which makes them less practical. A key feature of this SD3 is that it is neither too short nor too long (read the paper to learn more about this).
Scores
For this dark triad, you might be particularly interested in what is within the normal range. Scales can range from 1 to 5. Based on Professor Paulus' website, the following normal ranges are given for each of the three traits:
| Trait | Mean | Standard Deviation | Score above this is outside the normal range |
|---|---|---|---|
Machiavellianism |
3.1 |
0.76 |
> 3.86 |
Narcissism |
2.8 |
0.88 |
> 3.68 |
Psychopath |
2.4 |
1.0 |
> 3.40 |
| The scores above are subclinical, that means they are not indicative of personality disorders! |

Legal stuff
It seems that the the SD3 can be used for research, but you need to acknowledge the authors and their research paper when writing about it (References).

This is a simple scale question with some reverse coded items.
