Academic Motivation Scale-German Version (AMS-D)

Abstract

The Academic Motivation Scale—German Version (AMS-D; Möltner et al., 2024) was meticulously developed as a validated German translation of the original Academic Motivation Scale (AMS; Vallerand et al., 1989, 1992). This comprehensive, 28-item instrument is designed to assess study motivation based explicitly on the tenets of Self-Determination Theory (SDT). The scale comprises seven distinct factors representing the motivational continuum from intrinsic to amotivation. The rigorous translation process adhered to the internationally recognized TRAPD model, followed by extensive validation conducted with university students across Germany. Psychometric analysis, including Confirmatory Factor Analysis (CFA), confirmed the robust fit of the original seven-factor structure, and strong evidence for reliability and validity was established.

Purpose

The primary purpose of the AMS-D is to accurately and reliably evaluate the structure and level of academic motivation among German-speaking university students. By providing a multidimensional assessment, the scale enables researchers and educational professionals to categorize students’ motivational profiles according to the motivational continuum established within Self-Determination Theory (SDT).

The scale is intended for use in academic research, educational diagnostics, and intervention planning, allowing for targeted efforts to enhance autonomous motivation or address issues related to amotivation and highly controlled forms of extrinsic motivation in the higher education setting.

Construct

The AMS-D measures Academic Motivation, conceptualized as a continuum ranging from highly self-determined (intrinsic) to non-self-determined (amotivation). This conceptualization is rooted directly in Self-Determination Theory (SDT), which posits that the quality, rather than just the quantity, of motivation is crucial for optimal functioning and performance.

The scale operationalizes this construct through 28 items distributed across seven distinct subscales, covering the full spectrum of academic motivational regulation:

• Intrinsic Motivation Knowledge (IMK): Motivation derived from the pleasure of learning new things.
• Intrinsic Motivation Achievement (IMA): Motivation derived from the satisfaction of accomplishing difficult tasks.
• Intrinsic Motivation Stimulation (IMS): Motivation derived from the stimulating experiences associated with studying.
• Extrinsic Motivation Identified (EMID): Motivation based on valuing the academic goal personally.
• Extrinsic Motivation Introjected (EMIN): Motivation driven by internal pressures, such as guilt or ego enhancement.
• External Extrinsic Motivation (EME): Motivation controlled by external rewards or punishments (e.g., grades, money).
• Amotivation (AM): The absence of intention or motivation to act.

Validity

The validation study provided robust evidence across multiple facets of validity, supporting the structural integrity and predictive utility of the AMS-D in the German-speaking university population.

• Factorial Validity: Confirmatory factor analysis strongly supported the latent structure, confirming that the data adhered to the theoretically derived seven-factor model.
• Convergent Validity: The scale demonstrated expected positive correlations with related constructs, such as measures of work engagement and task orientation, indicating that the AMS-D successfully measures underlying motivational dynamics.
• Divergent Validity: The AMS-D showed appropriate differentiation from unrelated constructs, evidenced by weak positive associations between the controlled forms of motivation (EMIN and AM) and work avoidance.
• Criterion Validity: The factors successfully predicted relevant academic outcomes. Specifically, Study satisfaction correlated positively with the more autonomous factors (IMK, IMS, and EMID) and negatively with AM. Furthermore, cancellation intentions (intentions to drop out) were negatively predicted by autonomous motivation (IMK) and positively predicted by controlled motivation (EMIN) and Amotivation (AM).

Reliability

The AMS-D demonstrated strong internal consistency and acceptable temporal stability, confirming its reliability for both research and diagnostic applications.

• Internal Consistency: Measured using Cronbach’s alpha, the values for the seven subscales ranged from α = .72 to α = .89. These results indicate satisfactory to good homogeneity among the items within each factor.
• Test-Retest Reliability: The temporal stability of the measure was assessed via a one-week retest procedure, which yielded a correlation coefficient of r = .69. This figure suggests moderate to good consistency of scores over short periods.

Factor Analysis

A detailed Confirmatory Factor Analysis (CFA) was the primary method used to test the hypothesized seven-factor structure derived from Self-Determination Theory and the original AMS.

The seven-factor model provided a significantly superior fit to the data (χ² = 631.64, df = 329, p < .001) when compared against alternative, more parsimonious models (such as single- or three-factor structures). Key model fit indices confirmed the structural validity: CFI = .90, TLI = .88, RMSEA = .07, and SRMR = .07. These indices generally meet the acceptable threshold criteria for complex psychological measurement instruments.
