Method
Overview
The present study involved two separate samples of college students.
The first sample of 200 students received the Career Decision-Making Self-
Efficacy Scale-Short Form (CDMSE-SF; Betz, Klein, & Taylor, 1996), the
Skills Confidence Inventory (SCI; Betz, Borgen, & Harmon, in press; Betz,
Harmon, & Borgen, 1996), and the measures of generalized self-efficacy and
global self-esteem. The second sample of 147 students was administered the
CDMSE-SF, the Occupational Self-Efficacy Scale (OSES; Betz & Hackett,
1981), the Mathematics Self-Efficacy Scale (Betz & Hackett, 1983), and
the measures of generalized self-efficacy and global self-esteem.
Measures
Career Decision-Making Self-Efficacy Scale-Short Form (CDMSE-SF)
The CDMSE measures an individual’s degree of belief that he or she can
successfully complete tasks necessary to making career decisions. The
original basis for scale construction was the five career choice competencies
postulated in Crites’s (1978b) model of career maturity and assessed in
the Career Maturity Inventory (Crites, 1978a). Therefore, the item content
includes behaviors pertinent to (a) accurate self-appraisal, (b) gathering
occupational information, (c) goal selection, (d) making plans to implement
the decision, and (e) problem solving. The original scale included 10 items
reflecting each competency area. The original scale and subscales were
highly reliable; values of internal consistency reliability ranged from .86 to
.89 for the subscales, and was .97 for the total score. The 6-week test-retest
reliability was .83 (Luzzo, 1993).
The 25-item short form was developed using the best 5 items from each
of the five subscales, based on criteria described in Betz, Klein, and Taylor
( 1996). The shorter scales had reliabilities ranging from .73 (Self-Appraisal)
to .83 (Goal Selection), with the 25-item total score having an alpha of .94.
Using Osipow’s (1987) Career Decision Scale and Holland, Daiger, and
Power’s (1980) Vocational Identity Scale as criteria, the short form is as valid
as the long form.
The SCI was normed in samples of 1,147 employed adults and 706 college
students. Values of coefficient alpha ranged from .84 to .87 in the student
sample and from .84 to .88 in the employed adult sample. Within this
range, the Enterprising scale had the lowest alpha (.84 in both samples), and
the Realistic scale had the highest alpha (.87 and .88, respectively). Validity
data are provided in the SCI manual (Betz, Borgen, & Harmon, in press).
Values of alpha herein were .88 (R), .85 (1), .87 (A), .89 (S), .86 (E), and .89
(C).
Occupational Self-Efficacy Scale (OSES)
The 20-item OSES was developed by Betz and Hackett (1981) to measure
students’ perceptions of self-efficacy with respect to 20 commonly known
occupations. The instrument was originally developed to test the postulate
that the underrepresentation of women in many nontraditional (i.e., male-
dominated) career fields was due, in part, to women’s low expectations of
career-related self-efficacy with respect to male-dominated career fields.
Accordingly, the concept of traditionality versus nontraditionality was used
both to select occupational titles for inclusion in the instrument and as a
basis for scoring the instrument.
Based on percentages of women and men in the occupation, 10
traditionally female-dominated (traditional) and 10 traditionally male-
dominated (nontraditional) occupations were selected. Social worker and
engineer are examples of traditional and nontraditional occupations,
respectively. For each occupation, participants are asked to indicate the
strength of their beliefs that they could successfully complete the educational
requirements for that occupation. Responses were obtained on a 5-point
confidence continuum, ranging from 1 (no confidence at all) to 5 (complete
confidence). Total scores for traditionally female and traditionally male
occupations were computed as the sum of the confidence ratings for the 10
occupations associated with each. Evidence for reliability and validity has
been reported by Zilber (1988) and Layton (1984). For example, Layton
reported statistically significant relationships between traditional self-
efficacy and range of traditional options (.19 and .18 in two samples of
college students) and between nontraditional self-efficacy and range of
nontraditional options (.33 and .44 in the two samples). Values of coefficient
alpha in the present study were .85 and .83 for the 10-item Traditional
and Nontraditional subscales, respectively.
Mathematics Self-Efficacy Scale
The College Courses subscale of the Mathematics Self-Efficacy Scale
consists of 16 math or math-related college courses (e.g., computer science,
economics, geometry); the student is asked to indicate his or her degree of
confidence in the ability to complete each course with a final grade of A or
B. Responses were obtained on a 5-point scale ranging from 1 (no confidence
at all) to 5 (complete confidence). Betz and Hackett (1983) reported a
coefficient alpha of .93, and subsequent research (Lent, Lopez, & Bieschke,
1993) has provided evidence for the validity of the scale. The value of
coefficient alpha in the present study was .91.
Evidence for the validity of the USRS was shown by significant and
moderately sized relationships to other measures of self-esteem and
psychological adjustment (Betz et al., 1995) and to perceptions of both level
and unconditionality of regard from persons significant in the participant’s
childhood and adolescent years (Harshbarger, 1991). The value of alpha
herein was .92.
Results
Table 1 provides means, standard deviations, and t tests of gender
comparisons of the major variables. As shown in Table 1, male students
reported significantly higher levels of unconditional self-regard and
significantly higher scores on SCI Realistic and Conventional confidence
scales, the total SCI score, the nontraditional OSES, and the Mathematics
Self-Efficacy Scale. Female students reported significantly higher scores on
the SCI Social confidence scale. No significant gender differences in career
decision-making self-efficacy, traditional occupational self-efficacy, or on
the Investigative, Artistic, or Enterprising confidence scales were found.
Table 2 shows the correlations among total scores on the measures of
general and specific self-efficacy and unconditional self-regard. Correlations
in the upper row are those for male students, and those in the lower row are

.50 with the former and .43 and .39 with the latter). The SCI total score and
the Mathematics Self-Efficacy Scale score are significantly related to
generalized self-efficacy in both men and women, but only the SCI total score
is significantly related to global self-esteem.
A significant gender difference in pattern occurs in the relationships of
occupational self-efficacy to generalized self-efficacy and global self-esteem,
in which correlations are higher among male students. Although only the
difference for nontraditional occupational self-efficacy with unconditional
self-regard is statistically significant (r .32 among male students, and .01 =

greater than that in female students (.09), as is the Artistic and generalized
self-efficacy correlation (.38 vs..04, p < .01). The other correlations between
RIASEC theme confidence and generalized self-efficacy also fit the pattern
of closer relationships in male versus female students, although none of these

differences (.45 vs..27 for Investigative, .37 vs..25 for Social, .39 vs..31 for
Enterprising, and .46 vs..28 for Conventional) are statistically significant.
Correlations between unconditional-self-regard and RIASEC self-efficacy
scores are smaller in magnitude, although many are statistically
significant-the values range from .08 (Conventional) to .26 (Realistic) in
male students and from .11 (Realistic) to .32 (Enterprising) in female
students. Those for Realistic, Social, and Enterprising are statistically
significant among male students, and those for Investigative, Artistic,
Social, and Conventional are statistically significant among female students.
Because of the strong relationships of the career self-efficacy measures
to generalized self-efficacy, especially among male students, regressions
designed to indicate the strongest predictors of generalized self-efficacy
were undertaken separately within Samples 1 and 2 and within the male
and female subgroups. Table 4 provides the results of these regression
analyses. The first set of results is from the 200 students who were
administered the CDMSE-SF and the SCI, and the second set is from the
sample of 147 students who were administered the CDMSE-SF, the OSES,
and the Mathematics Self-Efficacy Scale.
It is evident from the data shown in Table 4 that career decision-making
self-efficacy is the most consistent predictor of generalized self-efficacy. In
Sample 1, the CDMSE-SF and generalized self-efficacy had in common
35% and 59% of their variance in female and male students, respectively,
with the RIASEC self-efficacy scores making little significant independent
contributions. When occupational and math self-efficacy as well as the
CDMSE-SF were used as predictors in the smaller sample, predictive
utility was reduced. The CDMSE -SF and math self-efficacy were
significantly related to generalized self-efficacy in female students. The
CDMSE-SF was the only significant predictor of generalized self-efficacy
in male students.
Discussion
The present study was designed to evaluate the relationships of domain-
specific measures of career self-efficacy to measures of generalized self-
efficacy and global self-esteem. Correlational data, analyzed separately
within gender, indicated generally stronger relationships of career self-
efficacy measures to generalized self-efficacy than to global self-esteem.
For example, in men, all five domain-specific measures of self-efficacy were
significantly related to generalized self-efficacy, but only the CDMSE-SF,
SCI total score, and OSES-nontraditional were significantly related to
global self-esteem. Among women, the CDMSE-SF, SCI, and Mathematics
Self-Efficacy Scale were significantly related to generalized self-efficacy, but
only the former two were related to global self-esteem. This pattern of
findings is consistent with theoretical expectation, in that domain-specific
self-efficacy is postulated to generalize to some degree to a belief in one’s
competence to handle new situations and behavioral challenges (generalized
self-efficacy), but not necessarily to a more affectively focused measure of
global self-esteem. However, the lower, but still statistically significant,
