Development of the Serenity Scale.

Serenity is a sustained inner peace. Nurses can use knowledge about serenity to help clients cope with harsh circumstances. The Serenity Scale is a 40-item self-report, summated scale that evaluates clients' serenity status. Critical attributes, identified by serenity experts, served as the theoretical framework. Sixty-five items were given to 542 male and female subjects age 20 to 95 (73% Caucasians and 27% minority) from varying income and educational levels yielding an alpha of .93. Forty items (SS.V2) were extracted for further analysis. The alpha coefficient was .92 with item-to-total correlations ranging from .25 to .67. Item means ranged from 2.6-3.7 (grand mean = 3.4). A principal components factor analysis with varimax rotation revealed nine factors explaining 58.2% of the variance. Limitations are that SS.V2 has not been tested with an independent sample and subjects with low educational levels had difficulty with some items.
