The Strengthspotting Scale measures your ability, frequency, and motivation to identify other people’s strengths, helping others with the application of their strengths, and the emotional satisfaction of doing so. There are twenty questions, four for each of the five categories, that have to be rated on a scale from 1 (Strongly Disagree) to 7 (Strongly Agree).

• ability - to identify strengths in others
• emotional – satisfaction of identifying strengths in others
• frequency – of identifying strengths in others
• motivation – to identify strengths in others
• application – helping others to utilize their strengths
  

You can get a hold of The Strengthspotting Scale in The Strengths Book: Be Confident, Be Successful, and Enjoy Better Relationships by Realising the Best of You, where it is included as part of the book to be released on April 28th, 2010. For research purposes The Strengthspotting Scale is freely available (upon request, no link yet) but understandably not for commercial purposes since it is copyrighted.

The only official link for The Strengths Book is on the CAPPEU site (if I find a link to the PDF I’ll post it).

The VIA Survey of Character Strengths is a scientifically validated measurement designed to identify what your top signature strengths are. It was developed from and is based on the multi-year work of Chris Peterson and Marty Seligman. They have identified, with a team of professionals, 24 Virtues and Character Strengths that are found across cultures.

If you are interested to learn more about how it came about, you can find the culmination of their work in their book called Character Strengths and Virtues: A Handbook and Classification, which is sometimes referred to as the un-dsm manual or more accurately it provides a counter balance to the DSM.
