This study developed and validated a new scale measuring effectance motivation, assessing its impact on self, objects, and people. The scale demonstrated good reliability and strong validity across multiple assessment methods.

Area of Science:

  • Psychology
  • Motivation Theory

Background:

  • Robert W. White's construct of effectance motivation is a key concept in understanding intrinsic drive.
  • Effectance motivation influences how individuals interact with and perceive their environment.

Purpose of the Study:

  • To develop a psychometrically sound scale to measure effectance motivation.
  • To assess the construct across three distinct dimensions: Effect on Self, Effect on Objects, and Effect on People.

Main Methods:

  • Scale development based on White's effectance motivation theory.
  • Reliability testing of the developed subscales.
  • Validity assessment using criterion groups, multitrait-multimethod matrix, and convergent/discriminant validity analyses.

Main Results:

  • The newly developed scale demonstrated good internal consistency for all three subscales.
  • Validity was supported through multiple rigorous methods, confirming the scale's accuracy.
  • The three dimensions of effectance (Self, Objects, People) were empirically supported.

Conclusions:

  • The developed scale is a reliable and valid instrument for measuring effectance motivation.
  • The findings support the multidimensional nature of effectance motivation as conceptualized.
  • This scale can be a valuable tool for research in motivation and related psychological fields.
