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

Another important area of the measurement to understand is validity. Whiston (2013) argues that validity addresses “what an instrument measures and how well it does that task” (pg. 58). Whiston (2013) explains that historically, validity has been separated into three distinct types: content-related validity, criterion-related validity, and construct validity. The first, content-related validity, addressed the degree to which the results of the test adequately represented the specific behavior. In order for a measurement to be valid, it must be appropriate for its intended use (Whiston, 2013). This form of validity is evident in the VMQ, because the data is comparable to other instruments that measure both motivational and values factors (Values and Motives Questionnaire, n.d). Next, criterion-related validity focuses mainly on the degree to which the measurement predicted the specific criterion (Whiston, 2013). The correlations within the VMQ appear to be average and independent of one another (Values and Motives Questionnaire, n.d). Finally, construct validity is concerned with the degree to which the test measures the intended behavior or construct. This entails that the instrument is appropriate for the test taker (Whiston, 2013). The Values and Motives Questionnaire accurately measures motivating factors and values among individuals. It appears the test provides the validity for both
