Description: The inventory measures achievement motivation considering its various components such as preference for difficult tasks, confidence in success, goal setting, competitiveness, persistence and others, thus enabling a profile diagnosis. It contains 170 items in total, constituting 17 scales. Scores can be also expressed in three factor scales: Self-Confidence, Ambition, and Self-Control.

Reliability: High internal consistency of the general score, satisfactory consistency indices in most of the scales. Test-retest reliability also examined.

Validity: Assessed using correlations with Achieving Tendency Test (MACH) scores and other psychological variables such as e. g. personality traits measured with the NEO-FFI, stress-coping styles, hope for success, also by comparing scores in several job groups, and of students from various departments.

Norms: The inventory has separate norms for men and women, developed for four groups:  high school students aged 15-19, students and professionally active adults aged 18-35, and 36-70. The normalization samples included over 5 thousand people.

Application: The tool can be applied in job counseling and selection, during decisions involving eployee allocation, development prognosis, career advancement as well as in research.

Description: Short version includes 30 items and the administration time is 3 minutes.  Examination is carried out in the way analogous to the full version. Points for answers are given in accordance with the key printed on a separate sheet.

Reliability: Reliability of the Polish version understood in terms of internal consistency proved satisfactory – the Cronbach alpha was .87 (whereas in the original German version it was .94).

Validity: Convergent validity of the LMI-K was tested using the correlation of its scores (N = 33) with those on the Mehrabian Achievement Tendency Scale (1994) which measures similar theoretical construct. The correlation found out was high (r =.80) and similar to the one for the general score in the LMI full version.

Norms: Separate T norms were developped for students aged 15-19, college and university students aged 18-28, professionally active persons aged 18-35 and 36-70, and (also separately) for males and females.

Applicability: Achievement motivation matters whenever the person is required to make his/her own independent decisions, to lead other people, plan, predict, as well as in time and human ressources management. The LMI-K is a fast and low-cost (in terms of both money and work spent) way to assess achievement motivation. This is important especially when the purpose of the examination is to select persons with high index of the general achievement motivation.
