Sh. Adams et Op. John, A HOSTILITY SCALE FOR THE CALIFORNIA PSYCHOLOGICAL INVENTORY - MMPI, OBSERVER Q-SORT, AND BIG-5 CORRELATES, Journal of personality assessment, 69(2), 1997, pp. 408-424
Using two samples, we developed and validated a hostility scale that c
an be scored from the California Psychological Inventory (CPI) and ser
ves as an alternate for the Cook-Medley Hostility Scale (He; Cook & Me
dley, 1954). The CPI Hostility (H) scale consists of 33 items that are
either duplicates or close equivalents of specific Ho items, and the
two scales correlate at least.90 in samples differing in sex. The H an
d Ho scales show a similar pattern of correlations with conceptually r
elevant MMPI scales and with observer-rated personality attributes tap
ping Barefoot, Peterson, et al.'s (1991) five hostility categories of
Hostile Affect, Cynicism, Aggressive Responding, Social Avoidance, and
Hostile Attributions. These findings provide evidence for the equival
ence of the two hostility scales, as well as external validation for t
hose personality characteristics that are purported to underlie the co
nstruct of hostility as tapped by both the original Ho scale and the n
ew CPI H scale.
