The Coopersmith Self-Esteem Inventory (CSEI) measures attitudes toward self in the context of pre-post evaluation, individual diagnosis, or classroom screening. From the CSEI Manual:
...self-image is the content of a person’s perceptions and opinions about [themselves]. The positive or negative attitudes and values by which a person views the self-image and the evaluations or judgments he or she makes about it form the person’s self-esteem.
The instrument consists of a brief self-report questionnaire and a school form for ages eight to fifteen years or adult form for ages sixteen and above. There is no time limit, but assessment typically takes fifteen minutes. It is hand scorable.
