Achievement Motivation Inventory

Achievement Motivation inventory (AMI) (Schuler, Heinz; Thornton, George C. III; Frintrup, Andreas & Mueller-Hanson, Rose; 2002) is a psychological test to assess a broad construct of job-related achievement motivation. It is used within personnel selection, promotion, I/O-psychological research, personality research and other applications in a work context.

17 Dimensions

AMI is assessing 17 dimensions of work related achievement motivation. These dimensions are:

Test Format

There are 170 Items on a 7-point-Likert-Scale. A short version will not cover all 17 dimensions but only contains 30 Items that best represent the total score. The 170-Item version takes appx. 30 Minutes to work on for the candidate and appx. 5-7 Minutes scoring for the Supervisor. The test can be administrated in single and in group sessions and is available as a paper-pencil test and in a web-based format with automated scoring.



Psychometrics

Reliability Reliability (Cronbach’s α) for the total score is α = .96, and ranges from α = .66 to α = .83 for individual scales. Retest reliability is rtt = .94 for the total score (rtt = .71 to rtt = .89 for single scales).

Content Validity Content validity has been demonstrated by extensive research on all major aspects of achievement motivation. Expert ratings ensured that only relevant aspects are included. Additionally, confirmatory factor analysis shows a good fit of the model to theory.

Construct Validity Construct validity is shown by correlations with related personality scales, e.g., Big Five inventories (ranging up to r = .72). Criterion related validity is indicated by prediction of grade point averages in US colleges (r = .22 for the total score and up to r = .29 for single scales) and early academic achievements (ranging between r = .21 to r = .36 on different scales).


Scocial Validity / Acceptance Studies have shown that there is high social validity in regard to acceptance of the test by examinees.

Norms

Reported in the Manual (2002): N = 335 US students; N = 410 US working adults; N = 1,267 German students; N = 166 German working adults. Additional norms for the German original are also available.

Additional applications in Czech Republic and the US (Lanik, M., Thornton, G. C. III. & Hoskovcova, S. (2009) report extend norm bases for the US and Czech Republic. Meaningful Score Differences between subgroups of students and workers in the Manual´s US Sample are reported by (Woo, S. E., Gibbons, A. M. & Thornton, G. C. III. (2007). A Norm of N=362 undergraduate students from Indonesia has been reported by Siaputra, I. B. (2013).

Critics

Whilst the broad construct of the Achievement Motiovation Inventory contains 17 "independend" subscales with each ten (10) items, exploratory and confirmatory factor analysis only reside in three factors (Self-Assurance, Ambition and Self-Control; c.f. Woo, S. E., Gibbons, A. M. & Thornton, G. C. III. (2007)). Hence, for practical applications a more narrow construct definition with a limited amount of items and shorter duration in test-taking might be favorable.
