Exploring Reliability and Validity- Values and Motives Questionnaire Exploring Reliability and Validity- Values and Motives Questionnaire The Values and Motives Questionnaire, also known as the Values and Motives Inventory, is designed to examine a person’s motivation in relation to his values and activities. In order to ensure a comprehensive understanding of values, the VMQ assess three distinct areas, including: interpersonal, intrinsic, and extrinsic. Interpersonal values, according to the VMQ refer to one’s relationships with others. Intrinsic values contain one’s personal beliefs and attitudes. Finally, extrinsic values are one’s motivating factors at the workplace. Each of these three areas contain twelve topics…show more content…
The internal consistency of this measurement used the coefficient alpha. The coefficients were all over .5, but they each had various ranges. Because the scale had such varying ranges, one could wonder if this could indicate a problem with errors? The VMQ shows an overall internal dependability and a low level of SEM. The internal consistency does surpass the requirements for a reliable instrument. According to authors of the VMQ (n.d), “…the scales approximate or exceed acceptable levels of internal consistency” (pg. 16). However, it is important to note that the scores of this test are not normally distributed, which impacts the standard deviations of the scores. While the deviation of the scores is acceptable, the test results did not have an extremely high correlation. The VMQ also demonstrated the validity scales having lower correlations (Values and Motives Questionnaire, n.d). One weakness of the reliability to consider is that the test was only compared to other tests that examined values. It did not compare values to those of other countries/cultures. Specific cultures and/or family systems have specific values that are instilled in them throughout the years. It would be beneficial to use this instrument in comparison to different demographic backgrounds. In doing this, one will be able to gain insight into how these differences can affect the results
