Ryff's Psychological Well being scale
Carol Ryff has conceptualized psychological well-being as consisting of 6 dimensions: autonomy, environmental mastery, personal growth, positive relations with others, purpose in life, self-acceptance. She has designed self-report scales to assess individual's well-being at a particular moment in time within each of these 6 dimensions. Three- to 12- item per scale validated versions exist of the measure for use in survey research or other data collection. Individuals respond to various statements and indicate on a 6-point Likert scale how true each statement is of them. Higher scores on each on scale indicate greater well-being on that dimension.
