Exploring Reliability and Validity Essay

The Values and Motives Questionnaire, also known as the Values and Motives Products on hand, is designed to analyze a person’s motivation regarding his ideals and activities. In order to assure a comprehensive comprehension of values, the VMQ examine three distinct areas, which includes: interpersonal, intrinsic, and extrinsic. Interpersonal values, according to the VMQ refer to one’s relationships with others. Intrinsic values include one’s personal beliefs and attitudes. Finally, extrinsic ideals are one’s motivating factors at the place of work. Each of these three areas include twelve topics addressed throughout the test. As the VMQ can be utilized for a variety of reasons, it is typically employed in the workplace as a guidance instrument. When exploring the Values and Motives Set of questions, it is important to know its dependability and quality. This conventional paper will addresses the measurement’s reliability and validity, including its rapport, strengths, and weaknesses. Sort of Reliability and Validity Relating to Whiston (2013), “reliability refers to the consistency of such measurements when the assessment procedure is repeated over a population of individuals or groups” (pg. 40). In its most basic form, trustworthiness refers investigates the dependability of the results. It also procedures the standard mistake of way of measuring (SEM) within the instrument. The SEM is actually a hypothesis of what the results would be in the event that someone required the test over and over again. Whiston (2013) continues to explain the many types of reliability, which include: test-retest, various or seite an seite forms, and internal persistence measures. The designers and authors from the Values and Motives Set of questions explain that the measurement utilized internal consistency reliability together with the sample (Values and Motives Questionnaire, n. d). Inner consistency of reliability simply means that the test out is broken into different sections. The results are than correlated. This form of reliability assess the measurement internally to determine its dependability (Whiston, 2013). Another important area of the measurement to know is quality. Whiston (2013) argues that validity details “what an instrument measures and just how well it can that task” (pg. 58). Whiston (2013) explains that historically, validity has been segregated into 3 distinct types: content-related quality, criterion-related validity, and develop validity. The first, content-related validity, resolved the degree that the benefits of the test out adequately displayed the specific patterns. In order for a measurement being valid, it should be appropriate for the intended make use of (Whiston, 2013). This form of validity is evident in the VMQ, because the data is comparable to various other instruments that measure equally motivational and values factors (Values and Motives Set of questions, n. d). Next, criterion-related validity focuses mainly around the degree where the dimension predicted the precise criterion (Whiston, 2013). The correlations within the VMQ is very much average and independent of one another (Values and Purposes Questionnaire, in. d). Finally, construct validity is concerned while using degree that the test measures the meant behavior or construct. This entails the instrument is suitable for test taker (Whiston, 2013). The Values and Motives Set of questions accurately procedures motivating elements and beliefs among individuals. It appears the test provides the quality for both content and construct but not for criterion-related validity (Values and Motives Questionnaire, and. d). Areas of Strength and Concern The Values and Motives Set of questions gave us internal uniformity reliability and SEM. The internal consistency of the measurement employed the coefficient alpha. The coefficients were all over. five, but they every single had numerous ranges. For the reason that scale got such various ranges, you could wonder if this can indicate a problem with problems? The VMQ shows an overall internal stability and a minimal level of SEARCH ENGINE OPTIMIZATION. The internal persistence does go beyond the requirements to get a reliable tool. According to authors with the VMQ (n. d), “…the scales estimated or go over acceptable degrees of internal consistency” (pg. 16). However , it is important to note which the scores of this kind of test are generally not normally allocated, which affects the standard deviations of the ratings. While the change of the results is acceptable, the test benefits did not offer an extremely substantial correlation. The VMQ also demonstrated the quality scales having lower correlations (Values and Motives Set of questions, n. d). One some weakness of the dependability to consider is that the evaluation was simply compared to different tests that examined values. It did not compare values to those of other countries/cultures. Specific civilizations and/or family members systems have certain values that are instilled in them throughout the years. It would be beneficial to use this instrument when compared to different market backgrounds. In doing this, one will be able to gain regarding how these differences can affect the benefits and ensure every persons happen to be adequately showed. Sample Size and Characteristics of Population The Ideals and Reasons Questionnaire researched a specific populace. It consisted of 159 MBA and mindset students (Values and Motives Questionnaire, d. d). While research does need to start someplace, this limited population will not likely produce benefits that signify the population overall. Using this certain population may lead to skewed effects, specifically inside the areas of achievements considering the total population that was studied were all continuing all their education. Clearly, not everyone in the standard population has received the chance to follow a college degree, let alone and MBA. This high level of feat would certainly alter the effects. It is important to note that the test size was relatively small , and well over 1 / 3rd of the little sample was psychology students. These factors need to be considered when evaluating the outcomes of the Values and Purposes Questionnaire. Personal Opinion General, I found the Values and Motives Customer survey to be very interesting. Assessing one’s subjective feelings and value systems can be not very easily empirically proven. However , the idea of the test appears beneficial. Yet , I do imagine the designers of the VMQ would gain more insight if they were to evaluate the leads to various cultures’ values. Making use of the results from varying cultures may have totally different effects than a select few of 159 college students. I actually do believe further research is necessary to provide more concrete information on the subject areas of the VMQ. Although the device proved to be equally reliable and valid, it truly is pertinent that further study be conducted to find higher correlations.
