A Norwegian translation of the Plutchik questionnaire for psychological defense

The reliability and validity of the Norwegian translation of Plutchik's Life Style Index (LSI) have been tested in a material of 704 individuals, 471 men and 233 women. The results showed low internal consistency for most of the subscales (Alpha ranging from 0.43 to 0.68). Several of the scales were also significantly correlated. Factor analyses showed that some of them loaded on common factors, indicating low specificity of the scales. Further, the validity of the test was not confirmed.
