Introducing Positive Psychology – A Practical Guide

First of all, measure your life satisfaction. You can use Diener and colleagues’ Satisfaction with Life Scale.
Then measure how you feel. To do this you can use the Positive and Negative Affect Scale (PANAS) which we look at in Chapter 11, or the Scale of Positive and Negative Experience (SPANE). See the Resources section for details of these assessment tools.
How did you fare? Were you surprised by the outcome? If the results weren’t as high as you’d like, how might you increase your life satisfaction and your positive mood, or decrease your negative mood? Write some notes in your well-being journal.
