Measures of motivation.

Area of Science:

• Psychology
• Educational Psychology

Background:

• The Orientation and Motivation Inventory (OMI) is a key tool for assessing adolescent psychological constructs.
• Previous research has established OMI's utility, but further validation across diverse student populations is beneficial.

Purpose of the Study:

• To test four new scales alongside replicating earlier findings for the OMI.
• To analyze motivational dimensions in a high school student sample.
• To identify and confirm underlying motivational factors in adolescent boys and girls.

Main Methods:

• Administered new scales and OMI to 159 boys and 166 girls across four high school grades.
• Utilized principal component analysis on 24 scale halves to identify factors.
• Employed varimax rotation for factor analysis of scale scores.

Main Results:

• Identified 11 factors for boys and 10 for girls from scale halves.
• Confirmed 10 of 12 postulated dimensions in the varimax solution for both sexes.
• Disclosed five similar second-order dimensions for boys and girls.

Conclusions:

• The study confirmed the structural validity of the OMI dimensions in a high school sample.
• Identified motivational dimensions include Status Seeking, Belief in own Potency, Seeking and Helping People, Theoretical Interests, and Risk-Taking preference.
• Findings support the OMI's applicability for understanding adolescent motivation across genders.
