Abstract

Use of social support as a concept of nursing research in Korea began about 1980. The multidimensional characteristic of the concept posed problems in operationalization and measurement, but many researchers used it in their research.
The objectives of this study were to examine the reliability of Korean translation of the NSSQ and PRQ, compare the construct and concurrent validity of the two instruments and discuss their use with Korean populations and to illustrate norms of social support in Korea. The subjects for the study were 312 nursing students and 294 nurses in their 20´ s of which 81 % were unmarried. The instruments were translated Korean versions of the NSSQ and PRQ.
The data analysis and results are as follows:
Reliability was examined by internal consistency using Cronbach´ s alpha. The alpha score for total support on the NSSQ was .94, and on the PRQ, .83
Construct validity was examined using Factor Analysis. For the NSSQ all six items loaded on one factor which accounted for 90.8% of the variance. On the PRQ five factors explained 55.4% of the variance, which increased when the items of "nurturing" was deleted.
Concurrent validity was examined using Pearson Correlation Coefficients. Correlation between NSSQ total functional support and PRQ Part I was low, but correlations between PRQ Part II and NSSQ total functional support and total social support were significant (r=.30, r=.17).
Levels of social support showed that on the NSSQ, total functional support had an average of 285.6, total social support, 108.09, and on the PRQ, the total support was 127.71. The order of subscores on the NSSQ was, for unmarried women, affirmation affection, aid and for married
women, aid, affection, affirmation. The order for sources of support was family, church members, and health professionals. On the PRQ, support was from parents, then, for married women, their husband, and then, for both friends and neighbors over siblings.
