Validity in a psychological assessment context
According to Foxcroft & Roodt (2013) Validity of a measurement refers to whether the test measures what it is supposed to measure and how effective it does so. “A psychological measure is valid for a specific purpose” (Foxcroft & Roodt, 2013).

Validity is a processes characterised by the interaction of both the sample and the purpose of the instrument. High validity is a result of a good valid interaction amongst the correct sample group and if the applicable instrument was used Foxcroft & Roodt, 2013). Low validity means that an aspect of the assessment is invalid or it can also be an indication that the whole assessment is invalid. As mentioned earlier in ‘Reliability in a psychological assessment context’ the three aspects of a measurement process that should be concise. These three aspects or questions are answered by the use of types of validity.

There are three types of validity and each address a different aspect of validity (Foxcroft & Roodt,

Construct identification procedures this refers to the degree to which it measures the theoretical construct that it is intended to measure. (Foxcroft & Roodt, 2013). Criterion-prediction procedures involve the calculation and accuracy of predictor and criterion. (Foxcroft & Roodt, 2013). Validity explores the magnitude to which a measurement’s instrument produces valuable results and the extent to which meaningful conclusions can be established (South African Journal for Industrial Psychology, 2015)
6. Validity of Occupational interest profile.
Criterion-related validity regarding of OIP was examined and the self-reported system and interest area, regarding current and ideal perceptions were calculated to be accurate in its assessment of respondents. Numerous measurements were made to determine whether assessment is valid and the researchers were satisfied with their findings (Rounds, Mazzeo, Smith, Hubert, Lewis & Rivkin,

    Reliability can be explained as the consistency of scores over time. Assessments are usually reliable when you get the same results regardless of when the assessment is taken or who does the scoring. On the other hand, Validity indicates how well an assessment actually measures what it is supposed to measure. Every assessment requires students to complete some task or activity and the validity of the task should reflect some knowledge or performance, and be consistent with current educational theory and practice. The quality of the assessment should be reliable because you would think that teachers thought carefully about the assessment before giving it to their students.…

    Reliability refers to the consistency, such as questionnaires or scales to assess how fearful a person is about something. Reliability of questionnaires or scales can be measured in terms of whether the test items are consistent, which is called test-retest reliability. Another way of assessing reliability is whether two independent assessors give similar scores, which is called inter-rater reliability. Test re-test refers to how consistent results are when the specific interview/questionnaire is repeated.…

    Alternate-form reliability is the degree of relatedness of different forms of the same test (Rosnow & Rosenthal, 2008), for example a human service researcher gave his or her client the same assessment that describes their characteristics but some of the wording and questions are different the results should be the same, if not the assessment needs to be redone. The second reliability is, Internal-consistency reliability: The overall degree of relatedness of all items in a test or all raters in a judgment study (also called reliability of components), (Rosnow &…

    Validity is the extent to which the research provides a true picture of the social reality of those being studied. So in Nayak’s study the validity is based on whether he provided a full picture of the lives of the ‘Charvers’ and ‘Real Geordies’. Naka’s study is high in validity as the students who were interviewed would be comfortable in opening up as they are in an environment that they are used to. Also the observation that took place provides strong validity as the working class males would act natural. Although there is the downfall that some of the participants may try to show off which will weaken the validity of the…

    Standardization is defined as the process by which test constructors ensure that testing procedures, instructions, and scoring are identical, or as nearly identical as possible, on every testing occasion. Standardizing a test is a very important process of administering the test to a representative sample of future test-takers in order to establish a basis for meaningful comparisons of scores. With that being said, reliability is the consistence or repeatability of a measure instrument. To establish reliability, researchers compare the consistency of test-takers’ scores on two halves of the test, alternate forms of the test, or retests on the same test. There are two types of reliability. Inter-Rater Reliability and Test-retest. Test-retest reliability is when the tester test the same people at different times but the participants should get the same results that he or she received on the previous test. The next reliability is Inter-rater and that is when multiple people are giving assessments of some kind or are the subjects of some test, then similar people should lead to the same resulting scores. It can be used to calibrate people, for example those being used as observers in an experiment. On the other hand, validity is the accuracy which a measuring instrument assesses the attribute that is designed to measure correlated with measures of school performance. In other words, validity refers to how well a test measures what it is purported to…

    Developing a measure of a psychological construct is a difficult and extremely time-consuming process if it is to be done correctly. Construct validity is an overarching type of validity, and includes face, content, criterion-related, predictive and concurrent validity and convergent and discriminant validity. Convergent validity is demonstrated by the extent to which the measure correlates with other measures designed to assess similar constructs. Discriminant validity refers to the degree to which the scale does not correlate with other measures designed to assess dissimilar constructs. Basically, by providing evidence of all these variations of construct validity (content, criterion-related, convergent and discriminant), you are establishing that your scale measures what it was intended to measure. Face validity refers to whether a measure appears “valid on the face.” In other words, it means that just by…

    The first measure to be examined is face validity which evaluates the extent that a measure appears to be valid to the group that the instrument is administered. One example, would be using a depression scale, “we would expect it to contain items about sadness, suicidal thoughts, grief, crying spells, and lack of energy. However, if the scale included items that asked about our hair color, favorite flavor of ice cream, and feelings regarding cats, it would not make sense on the face of it” (Krysik & Finn, 2013, p.262). As a result, the scale for depression would not be taken seriously as a measure of depression and the negative feelings could affect the way we answer the questions. In contrast, construct validity measures the way other variables are related within a system. “Basically, construct validity implies that the developers of standardized instruments form hypothesis…

    For most people tests occur throughout one 's life. People are administered tests for school, work, and other reasons. Testing can be for various reasons and there are different categories of testing. The major categories of tests are mental ability tests, achievement tests, personality tests, interests and attitudes, and neuropsychological tests. In order to ensure accuracy with testing, it is important to question, compare, and contrast reliability and validity of tests. Reliability deals with the stability of scores and measured traits and validity questions the purpose of the tests and what it measures (Hogan, 2007). Tests are also categorized by how they are given and by how much time one has to complete a test. The reason tests exist is because of the different needs people have, such as scientific reasons, medical reasons, or administrative reasons. Testing individuals can provide much-needed answers for production, progress, and even for life saving reasons.…
