The Sense of Coherence (SOC) Scale purports to measure a disposition which engenders, sustains, and enhances health. However, reports of high negative correlations (average about À0.7) with negative aectivity (NA) measures raise doubt as to whether it does not only measure the absence of neuroticism. These relationships could also be interpreted as validation of the scale, if the low end of NA is conceived as emotional stability. In samples of nursing students, managerial and administrative personnel and life insurance consultants, the SOC scale related negatively to NA scales, and positively to positive aectivity scales, but more strongly to NA. An emotional stability scale correlated positively with the SOC scale, supporting the alternative interpretation. Stepwise multiple-regression analyses con®rmed the bivariate ®ndings but also indicated that from 25 to 47 per cent of SOC variability remained unexplained after the trait scales' predictions. The SOC appears to be a highly complex construct which partakes in a mixture of personality domains, and is taxonomically above the trait level.
