الملخص EN

The current study aimed to investigate the psychometric properties of the Revised Achievement Motivation Scale (AMS- R) in the Omani environment.

The study sample consisted of (486) students from A'Sharqiyah University, using the psychometric descriptive approach.

The results of the study indicated that the scale has good psychometric properties.

As the items on the scale had a high discriminatory ability that ranged between (0.

48-0.

62), and internal consistency reliability coefficients amounted to (0.

77-0.

84) for the two dimensions of the scale, and an overall reliability coefficient (0.

78).

The scale had an Acceptable Criterion- related Validity through its statistically significant relationship with self-efficacy.

The results of the exploratory factor analysis indicated two factors that explained the performance on the scale, namely : hope for success, and Fear of failure, as these two factors explained approximately (57%) of the variance of performance on the scale.

The results of the confirmatory factor analysis confirmed the stability of the factorial structure of the scale, after deleting item 2.

As well as the indicators of the Composite reliability of the two dimensions of the scale (0.

81-0.

84).

The indications of convergent and Discriminant validity were acceptable for the dimensions of the scale.

The study recommended the use of the scale by researchers because of its good psychometric properties.
