Exploring Reliability and Validity Essay

The value and Motives Questionnaire, also known as the value and Motives Inventory, is designed to examine a persons motivation in relation to his value and activities. In show to vouch a comprehensive pinch of set, the VMQ assess three unvarnished argonas, including interpersonal, intrinsic, and extrinsic. social values, according to the VMQ refer to nonp beils relationships with otherwises. Intrinsic values gestate 1s personal beliefs and attitudes. Finally, extrinsic values are ones incite factors at the study. Each of these three areas contain twelve topics addressed during the stress. plot the VMQ bunghole be utilise for a regeneration of reasons, it is typically used in the workplace as a guidance tool. When exploring the set and Motives Questionnaire, it is classical to run across its dependableness and hardihood. This composition will address the cadences reliability and validity, including its coefficients, strengths, and weaknesses.Type of Reliabil ity and hardihoodAccording to Whiston (2013), reliability refers to the soundbox of such measurements when the rendering procedure is repeated on a people of individuals or aggroups (pg. 40). In its simplest form, reliability refers examines the bona fideness of the scores. It also measures the warning error of measurement (SEM) within the official document. The SEM is a hypothesis of what the scores would be if soulfulness took the assay to a greater extent than once. Whiston (2013) continues on to justify the various types of reliability, including test-retest, alternate or line of latitude forms, and internecine eubstance measures. The designers and authors of the determine and Motives Questionnaire formulate that the measurement used internal consistency reliability with the experiment (Values and Motives Questionnaire, n.d). Internal consistency of reliability simply means that the test is divided into different sections. The scores are than correlated. This form of reliability assess the measurement internally to determine its reliability (Whiston, 2013). other important area of the measurement to understand is validity. Whiston (2013) argues that validity addresses what an instrument measures and how come up it does that tax (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 ground level to which the results of the test adequately represented the specific behavior. In order for a measurement to be valid, it must be grant for its intend 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 c riterion (Whiston, 2013).The correlations within the VMQ appear to be average and separate of one a nonher (Values and Motives Questionnaire, n.d). Finally, construct validity is concerned with the degree to which the test measures the mean behavior or construct. This entails that the instrument is appropriate for the test taker (Whiston, 2013). The Values and Motives Questionnaire accurately measures cause factors and values among individuals. It appears the test provides the validity for both content and construct but non for criterion-related validity (Values and Motives Questionnaire, n.d).Areas of Strength and ConcernThe Values and Motives Questionnaire gave us internal consistency reliability and SEM. The internal consistency of this measurement used the coefficient alpha. The coefficients were all over .5, but they severally had various ranges. Because the scale had such variable ranges, one could wonder if this could indicate a problem with errors? The VMQ shows an ove rall internal dependability and a low level of SEM. The internal consistency does surpass the requirements for a sure instrument. According to authors of the VMQ (n.d), the scales approximate or happen 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 alsodemonstrated the validity scales having lower correlations (Values and Motives Questionnaire, n.d). i weakness of the reliability to consider is that the test was only analysed 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 dependable to use this instrument in comparison to different demographi c backgrounds. In doing this, one will be able to watch insight into how these differences can affect the results and ensure all persons are adequately represented. try Size and Nature of PopulationThe Values and Motives Questionnaire studied a specific nation. It consisted of 159 MBA and psychology students (Values and Motives Questionnaire, n.d). While research does need to down somewhere, this limited population will not produce results that represent the population as a whole. victimization this specific population may lead to skewed results, specifically in the areas of achievement considering the total population that was studied were all continuing their education. Clearly, not everyone in the general population has had the endangerment to pursue a college degree, let simply and MBA. This high level of achievement would sure as shooting skew the results. It is important to note that the sample size was relatively weensy and well over one third of the small sample was psychology students. These variables need to be taken into consideration when assessing the results of the Values and Motives Questionnaire. face-to-face OpinionOverall, I found the Values and Motives Questionnaire to be very interesting. Assessing ones subjective feelings and value systems is not well empirically proven. However, the idea of the test seems beneficial. However, I do believe the designers of the VMQ would gain more insight if they were to compare the results to various cultures values. Using the results from varying cultures will have alone different results than a small group of 159 college students. I do believe besides research is needed to provide more concrete information on the topics of the VMQ. Although the instrument proved to be both reliable and valid, it is pertinent that further research be conducted to find higher correlations.ReferencesValues and power questionnaire The technical manual.
