Anger Expression
Title:   Anger Expression (AX) Scale
Primary Reference:

. Spielberger CD et al: The experience and expression of anger: Construction and validation of an
anger expression scale.  In MA Chesney, RH Rosenman (Eds.), Anger and Hostility in Cardiovascular
and Behavioral Disorders.  Hemisphere: Cambridge, 1985.
Type of Measure:  Used without modification.
Role in Center Model:  Chronic/Stable Burdens and Resources:  Personal Attributes
Purpose:  To assess tendencies to express anger openly (Anger-out) and to suppress anger or keep
it in (Anger-in).  Anger suppression is thought to have deleterious effects on mental and physical
functioning, and has been linked to CHD, cancer, and infectious disease.
Description:  Subjects rate how often they behave in certain ways when they are “angry or furious”
using a 4-point rating scale.  No time frame or referent period is used.
Scaling:  1 = Almost Never, 2 = Sometimes, 3 = Often, 4 = Almost Always
# items:   16 (8 Anger-out and 8 Anger-in)
Sample items:  “I lose my temper” “I say nasty things” (Anger-out)
“I keep things in” “I boil inside, but I don’t show it” (Anger-in)
Original Psychometric Data:  high school students (n=1,114)
Reliability:  Anger-in: males, alpha = .84; females = .81
Anger-out: males = .73; females = .75
(Anger-in & Anger-out are uncorrelated/independent dimensions.)
Validity:     Related to other measure of “suppressed hostility” (Harburg et al.) in
expected ways.
Correlates with state and trait anger and anxiety in expected ways;
uncorrelated with state/trait curiosity.
Higher Anger-in related to higher blood pressure; higher anger-out related to
somewhat lower BP.

Big Five Personality Factors
Title:  Goldberg’s Adjective Scale 
Primary Reference
Goldberg LR: The development of markers for the big-five factor structure.
Psychol Assess 4:26-42, 1992.
Type of Measure:  Modified from original.  To reduce respondent burden, a 25-item version rather than the original 100-item scale was employed.  The five highest loading items from each factor were used.  In addition, modifications of the scaling technique were also adopted (see below).
Role in Center Model:  Chronic/Stable Burdens and Resources:  Personal Attributes
Purpose:  To assess standing along five major dimensions of personality: (1) extraversion,
(2) agreeableness, (3) conscientiousness, (4) neuroticism, and (5) openness.  There is a growing
consensus that these five traits provide the fundamental underpinnings of human personality.
Several of these traits have been shown to have health consequences or to be related to underlying
physiological responses.
Description:  Subjects are instructed to rate how accurately various single-word traits describe
themselves.  There are specific instructions to “describe yourself as you see yourself at the present
time, not as you wish to be in the future.  Describe yourself as you are GENERALLY or TYPICALLY,
as compared with other persons you know of the same sex and roughly the same age.”
Scaling: Original: 1 = extremely inaccurate, 2 = very inaccurate, 3 = quite inaccurate,
4 = slightly inaccurate, 5 = neither inaccurate nor accurate, 6 = slightly accurate,
7 = quite accurate, 8 = very accurate, 9 = extremely accurate
Modified:  0 = Not at all accurate, 1 = A little accurate, 2 = Moderately accurate,
3 = Quite a bit accurate, 5 = Extremely accurate
# items:  25 (5 for each of the five dimensions).
Sample items:  “bashful” (reversed), “talkative” (extraversion)
“pleasant” “unkind” (reversed) (agreeableness)
“organized” “careless” (reversed) (conscientiousness)
“irritable” “nervous” (neuroticism)
“innovative” “unimaginative” (reversed) (openness)
Original Psychometric Data:  college students (n = 320)
Reliability:  extraversion, alpha = .90; agreeableness = .84; conscientiousness = .88;
neuroticism = .83; openness = .82
Validity:  High correlations with scales based on larger numbers of items.
High to moderate correlations (.46 to .69) with McCrae & Costa’s NEO
Personality Inventory.

Hostility 
Title:   The Cook-Medley Hostility Scale (Ho)
Primary Reference:
Cook WW, Medley DM: Proposed hostility and pharisaic-virtue scales for the MMPI.
J Appl Psychol 38:414-418, 1954. 
Type of Measure:  Modified from original. The modified 20-item version of the scale consists of
three sub-scales which were found to be better predictors of health outcomes than the whole 50-item
scale. These subscales are: Cynicism, Hostile Affect and Aggressive Responding (Barefoot, Dodge,
Peterson, Dahlstrom, & Williams, 1989).
Role in Center Model:  Chronic/Stable Burdens and Resources:  Personal Attributes
Purpose:  To assess people’s cynical, mistrustful and aggressive attitudes toward others.
Hostility has been linked to all-cause mortality, CHD, and a number of cardiovascular risk factors. 
Description:  Subjects indicate by using “True/False” options whether each of the 20 statements
describes them correctly. No time frame or referent period is used.
Scaling:  1 = True, 2 = False
# items:   20 (6 Cynicism, 5 Hostile Affect, and 9 Aggressive Responding)
Sample items:  “I would certainly enjoy beating a crook at his or her own game”
(Aggressive Responding) “People often disappoint me” (Hostile Affect)
“I think most people would lie to get ahead” (Cynicism)
Original Psychometric Data:  graduate students (n=200)
Reliability:  Whole sample, alpha = .84
Validity:  Correlates with Minnesota Teacher Attitude Inventory (MTAI) (Cook & Medley, 1954)
Correlates with trait anger and relevant hostility subscales of Buss and Durkee
Hostility Inventory in expected ways (Smith & Frohm, 1985);
Correlates negatively with Rotter Trust Scale, Social Desirability, and Hardiness
(Smith & Frohm, 1985).

Mastery
Title:   The Mastery Scale 
Primary Reference:
Pearlin LI, Schooler C: The structure of coping. J Health Soc Behav 19:2-21, 1978.
Type of Measure:  Used without modification.
Role in Center Model:  Chronic/Stable Burdens and Resources:  Personal Attributes
Purpose:  To assesses the extent to which the individuals generally feel as though they manifest
personal mastery over important life outcomes. Mastery has been linked to depressive symptoms.
Description:  Subjects are asked to rate how much they agree or disagree with self-descriptive
sentences. No time frame or referent period is used.
Scaling:  1 = Strongly Disagree, 2 =  Disagree, 3 = Agree, 4 = Strongly Agree
# items:   7
Sample items:  “There is really no way I can solve some of the problems I have”
(reversed) “What happens to me in the future mostly depends on me”
“I can do just about anything I really set my mind to do”
Original Psychometric Data:  people from the Census-defined urbanized area of Chicago
ages 18-65 (n=2300)
Reliability:  Whole sample, alpha = not reported 
Validity:    Plays important role in coping with stress.
Correlates with optimism in expected direction, but predicts levels of depressive
symptoms independent of optimism (Marshall & Lang, 1990).

anxiety,self-mastery, and self-esteem): A re-evaluation of the Life Orientation Test.
J Pers Soc Psychol 67:1063-1078, 1994.
Type of Measure:  Used without modification.
Role in Center Model:  Chronic/Stable Burdens and Resources:  Personal Attributes
Purpose:  To measure dispositional optimism. Dispositional optimism is considered beneficial for
psychological and physical well-being. It is related to faster recovery after coronary artery bypass
surgery (Scheier, et al. 1989) and lower rates of re-hospitalization following angioplasty
(Helgeson & Fritz, 1999).
Description:  Respondents indicate the extent to which they agree with statements describing
optimism about life. No time frame or referent period is used.
Scaling:  0 = Strongly Disagree, 1 = Disagree, 2 = Neutral, 3 = Agree, 
4 = Strongly Agree
# items:   10 (6 scale items + 4 filler items)
Sample items:  “If something can go wrong for me, it will” (reversed)
“In uncertain times, I usually expect the best”
“I am always optimistic about my future” 
Original Psychometric Data:  undergraduate students (n=2055)
Reliability:  Whole sample, alpha = .78 
Test-Retest Reliability (28 months) = .79
Validity:    Correlates with related constructs like self-mastery;

Self-Esteem
Title:   Rosenberg Self-Esteem Scale
Primary Reference:
Rosenberg, M. (1965). Society and adolescent self-image. Princeton, NJ: Princeton University Press.
Type of Measure:  Modified from original. Four items were chosen out of the original ten items
 (Krause, 1995). 
Role in Center Model:  Chronic/Stable Burdens and Resources:  Personal Attributes
Purpose:  To measure self-esteem. Self-esteem, in conjunction with mastery and optimism,
predicted low rates of re-hospitalization following angioplasty (Helgeson & Fritz, 1999).
Description:  Respondents indicate the extent to which they agree with sentences describing
attitudes about themselves. No time frame or referent period is used.
Scaling:  1 = Strongly Disagree, 2 = Disagree, 3 = Agree, 4 = Strongly Agree
# items:   4
Sample items:  “I feel that I have a number of good qualities” “I take a positive 
attitude toward myself” 
Original Psychometric Data:  undergraduate students (n=1103) (Krause, 1995).
Reliability:  Whole sample, alpha = .89. It has demonstrated internal consistency
and high test-retest reliability in numerous studies.
Validity:    One of the most widely used instruments to measure self-esteem,
it consistently demonstrates a unidimensional nature.

Primary Reference:
Katz JN, Chang LC, Sangha O, Fossel AH, Bates DW: Can comorbidity be measured by
questionnaire rather than medical record review? Medical Care 34:73-84, 1996.
Type of Measure:  Modified from original. A number of health problems not included in the original
questionnaire were added. Questions related to illness severity were excluded in order to create a
simple count of health problems.
Role in Center Model:  Chronic/Stable Burdens and Resources:  Personal Attributes
Purpose:  To assess the number of health problems experienced by the participant.
Description:  Respondents indicate by Yes/No whether they have had a particular health problem.
Scaling:  N/A
# items:   23
Sample items:  “Have you ever had a heart attack?” “Have you ever had a stroke?”
“Do you have diabetes?”
Original Psychometric Data:  patients over 50 years old (N=170) 
Reliability:  Test/Retest reliability (24 hours) intraclass correlation coeff. =.91
Validity:    Correlated strongly with Charlson comorbidity index
(Spearman correlation coeff. =.63).
Correlated positively with health care utilization among patients.
