Key Descriptions

  • 240-item measure
  • 5-point Likert Scale ranging from “strongly disagree, disagree, neutral, agree, and strongly agree.”
  • Measures the 5 Factor Domains of neuroticism, extraversion, openness, conscientiousness, and agreeableness.
  • Measures 30 underlying facets of the 5 Factor Model of personality.
  • Provides minimum and maximum scoring for normative behavior.
  • Subscale measured through the conversion of scores into a t-test, with a mean of 50, and a standard deviation of 10.
  • Note that results may not be interpretable if more than 40 items are missing (Costa & McCrae, 1976).

  • Neuroticism

  • Extraversion
    • T1 (entry) SEM = 1.61
    • T2 (3-month follow-up) SEM = 1.91
    • T3 (6-month follow-up) SEM = 1.71
  • Openness
    • T1 (entry) SEM = 1.44
    • T2 (3-month follow-up) SEM = 1.45
    • T3 (6-month follow-up) SEM = 1.97
  • Agreeableness
    • T1 (entry) SEM = 2.10
    • T2 (3-month follow-up) SEM = 1.73
    • T3 (6-month follow-up) SEM = 1.80
  • Conscientiousness
    • T1 (entry) SEM = 1.68
    • T2 (3-month follow-up) SEM = 1.57 
    • T3 (6-month follow-up) SEM = 1.56

Cut-Off Scores

Vocational Rehabilitation Population: (Holland, Holland, Dollinger, & MacDonald, 1995; n = 85)

  • Neuroticism – Min 33, Max 83, mean 56.48, SD 11.49

  • Openness – Min 29, Max 68, mean 46.63, SD 8.22 o
  • Agreeableness – Min 15, Max 72, mean 44.86, SD 10.96 
  • Conscientiousness – Min 27, Max 67, mean 45.50, SD 8.9
  • Scores below the minimum and/or above the maximum were considered abnormal

 

Outpatient, Drug Rehabilitation: (Ciarrocchi & Piedmont, 1999; n = 99)

  • On all scales (as recommended by Costa and McCrae in assessment manual)
    • Minimum scores lower than 45
    • Maximum scores higher than 55
    • Scores below the minimum and/or above the maximum were considered abnormal

Normative Data

Normative Report of United States Population: (as reported in Allen, Murray, Rawlings, & Trinder, 2003; n = 1539)

  • Neuroticism – mean 19.1, standard deviation 7.7 
  • Extraversion – mean 27.7, standard deviation 5.9 
  • Openness – mean 27.0, standard deviation 5.8 
  • Agreeableness – mean 32.8, standard deviation 5.0 
  • Conscientiousness – mean 34.6, standard deviation 5.9

Test/Retest Reliability

Study Among Longitudinal Study of Aging: (Costa, McCrae, Trull, Useda, 1995; predictive reliability consistent across scoring at 3-month and 6-month follow-up; p < .01, p < .001)

  • Neuroticism Excellent (ICC = .88, .89, .79) 
  • Extraversion Excellent (ICC = .80, .80, .79) 
  • Openness Excellent (ICC = .86, .85, .84) 
  • Agreeableness Excellent (ICC = .83, .78, .76) 
  • Conscientiousness Excellent (ICC = .89, .86, .84)

 

Outpatient, Drug Rehabilitation: (Ciarrocchi and Piedmont, 1999; p < .001)

  • Neuroticism Adequate (ICC = .52)
  • Extraversion Adequate (ICC = .73) 
  • Openness Excellent (ICC = .79) 
  • Agreeableness Excellent (ICC = .77) 
  • Conscientiousness Adequate (ICC = .66)

 

Reported in Test Manual: (Costa and McCrae, 1992) 

  • Notable long-term stability, suggesting high retest reliability

Internal Consistency

Reported in Test Manual: (Costa and McCrae, 1992) 

  • Neuroticism Excellent (ICC = 0.92 Self-Report; ICC=0.93 Observer Rating)
  • Extraversion Excellent (ICC = 0.89 Self-Report; ICC=0.90 Observer Rating)
  • Openness Excellent (ICC = 0.87 Self-Report; ICC=0.89 Observer Rating)
  • Agreeableness Excellent (ICC = 0.86 Self-Report; ICC= 0.95 Observer Rating)
  • Conscientiousness Excellent (ICC = 0.90 Self-Report; ICC=0.92 Observer Rating)

 

Study Among Longitudinal Study of Aging: (Terracciano, et al., 2005)

  • Neuroticism Excellent (ICC = 0.91)
  • Extraversion Excellent (ICC = 0.87)
  • Openness Excellent (ICC = 0.87) 
  • Agreeableness Excellent (ICC = 0.88) 
  • Conscientiousness Excellent (ICC = 0.92)

 

Personality in Younger and Older Adults: (Van den Broeck, et al., 2012)

  • Neuroticism Excellent (ICC = 0.92 (younger adults); ICC = 0.91 (older adults))
  • Extraversion Excellent (ICC = 0.87 (younger adults); ICC = 0.84 (older adults))
  • Openness Excellent (ICC = 0.87 (younger adults); ICC = 0.85 (older adults))
  • Agreeableness Excellent (ICC = 0.87 (younger adults); ICC = 0.88 (older adults)) 
  • Conscientiousness Excellent (ICC = 0.90 (younger adults); ICC = 0.89 (older adults))

Criterion Validity (Predictive/Concurrent)

Predictive validity: 

 

NEO-PI-R for police officers: (Chibnall, Detrick, and Leubbert, 2004)

  • Higher openness and lower extraversion were predictive of better academic performance within the police academy o 
  • Neuroticism was predictive of Firearms performance o 
  • Higher scores of neuroticism was predictive of lower rates of absenteeism
  • Combined lower scores of conscientiousness and openness and higher Extraversion was predictive of better physical activity performance

 

NEO-PI and Emotional Exhaustion and Burnout among college students: (Burns and Periard, 2013)

  • Agreeableness accounted for 6.2% of the variance for emotional exhaustion
  • Conscientiousness accounted for 12.1% of the variance for emotional exhaustion

Construct Validity

Reported in Test Manual: (Costa and McCrae, 1992) 

  • Convergent: Correlation between alternate measures of similar tests and NEO-PI-R facet scales 
  • Discriminant: contrasts the correlates of different facets of the NEO-PI-R, looking primarily at facets that fall under the same domain

Content Validity

Addressed through selecting six distinct facets from personality literature that fall within each main domain (e.g. neuroticism), then measuring each facet with non- redundant items (Costa and McCrae, 1992)

Face Validity

The use of self-report (True-False) items is typical of vocational interest and personality test
