evaluated and included as independent variables. The charac-
teristics used as independent variables consisted of the 13
vulnerability scales of the Index of Vulnerability, total
vulnerability, three clusters of vulnerability scales, three
structural indices of social support, and socioeconomic
status. The matrix of intercorrelations of psychosocial
variables is included as Table 52, Appendix G. Also, the
disease variable co-morbidity was included in this part of
the analysis and related findings are reported in this sec-
tion. The dependent variable was the survival quotient, a
value which reflected longer or shorter than expected
survival.
Descriptive study
Descriptive statistics for the 13 scales of the Index
of Vulnerability are presented in Table 19. The ratings on
these scales for the 30 individuals in the sample reflected
greatest variation among the individuals in terms of turmoil,
frustration, and depression, and least differences in terms
of hopelessness and denial. The scales with the highest mean
values were powerlessness, anxiety, and exhaustion. Those
with the lowest mean values were worthlessness and repudia-
tion of key others. Values of total vulnerability, which was
the sum of the 13 items, ranged from 16.5 to 38.5 with a mean
of 27.07 and a standard deviation of 5.96.
