Most questionnaires of scales focus on negative aspects of the quality of life or deficits of well-being. This small 5 item scale was developed by Ed Diener, one of the leading psychologists with special interest in subjective wellbeing. Here is his SWLS Scale (which is public domain and a great and very interesting tool!)

Below are five statements that you may agree or disgree with. Using the 1 - 7 scale below, indicate your agreement with each item by placing the appropriate number on the line preceding that item. Please be open and honest in your response.

Scale: 7 - Strongly agree 6 - Agree 5 - Slightly agree 4 - Neither agree nor disagree 3 - Slightly disagree 2 - Disagree 1 - Strongly disagree
		In most ways my life is close to my ideal.
		The conditions of my life are excellent.
		I am satisfied with my life.
		In most ways my life is close to my ideal
		If I could live my life over, I would change almost nothing.
	Interpretation of the result: 35 - 31 Extremely satisfied 26 - 30 Satisfied 21 - 25 Sligthly satisfied 20 Neutral 15 - 19 Slightly dissatisfied 10 - 14 Dissatisfied 5 - 9 Extremely dissatisfied
