Construct Validity
Construct validity concerns how well a set of indicators represent or reflect a concept that is not directly measurable. ''Construct validation'' is the accumulation of evidence to support the interpretation of what a measure reflects.Polit DF Beck CT (2012). Nursing Research: Generating and Assessing Evidence for Nursing Practice, 9th ed. Philadelphia, USA: Wolters Klower Health, Lippincott Williams & Wilkins Modern validity theory defines construct validity as the overarching concern of validity research, subsuming all other types of validity evidence such as content validity and criterion validity. Construct validity is the appropriateness of inferences made on the basis of observations or measurements (often test scores), specifically whether a test can reasonably be considered to reflect the intended construct. Constructs are abstractions that are deliberately created by researchers in order to conceptualize the latent variable, which is correlated with scores on a given me ...

Test Validity
Test validity is the extent to which a test (such as a chemical test, chemical, physical test, physical, or test (assessment), scholastic test) accuracy and precision, accurately measures what it is supposed to measurement, measure. In the fields of psychological testing and test (assessment), educational testing, "validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests". Although classical models divided the concept into various "validities" (such as content validity, criterion validity, and construct validity), the currently dominant view is that validity is a single unitary construct. Validity is generally considered the most important issue in psychological and educational testing because it concerns the meaning placed on test results. Though many textbooks present validity as a static construct, various models of validity have evolved since the first published recommendations for constructing psy ...

Future Orientation
In psychology and related fields, future orientation is broadly defined as the extent to which an individual thinks about the future, anticipates future consequences, and plans ahead before acting. Across development, future orientation is particularly important during periods of major changes, for example during the transition from adolescence to adulthood, when youth must make choices about social groups, academic paths, as well as risky behaviors like drug and alcohol use, and sexual activity. Several models have been developed to describe the various factors that combine to impact future orientation. Perspectives on future orientation There are several different ways that future orientation has been observed and measured in research. The most prominent constructs include possible selves, optimism, time perspective, delay discounting. While different in definition, all of these constructs are thought to tap into and impact how people think and plan for the future. Despite the m ...

Self-concept
In the psychology of self, one's self-concept (also called self-construction, self-identity, self-perspective or self-structure) is a collection of beliefs about oneself. Generally, self-concept embodies the answer to the question ''"Who am I?".'' The self-concept is distinguishable from self-awareness, which is the extent to which self-knowledge (psychology), self-knowledge is defined, consistent, and currently applicable to one's Attitude (psychology), attitudes and dispositions. Self-concept also differs from self-esteem: self-concept is a cognitive or descriptive component of one's self (e.g. "I am a fast runner"), while self-esteem is evaluative and opinionated (e.g. "I feel good about being a fast runner"). Self-concept is made up of one's self-schemas, and interacts with self-esteem, self-knowledge, and the social self to form the self as a whole. It includes the past, present, and future selves, where future selves (or possible selves) represent individuals' ideas of w ...

Self-esteem
Self-esteem is confidence in one's own worth, abilities, or morals. Self-esteem encompasses beliefs about oneself (for example, "I am loved", "I am worthy") as well as emotional states, such as triumph, despair, pride, and shame. Smith and Mackie define it by saying "The self-concept is what we think about the self; self-esteem, is the positive or negative evaluations of the self, as in how we feel about it (see self)." The construct of self-esteem has been shown to be a desirable one in psychology, as it is associated with a variety of positive outcomes, such as academic achievement, relationship satisfaction, happiness, and lower rates of criminal behavior. The benefits of high self-esteem are thought to include improved mental and physical health, and less anti-social behavior while drawbacks of low self-esteem have been found to be anxiety, loneliness, and increased vulnerability to substance abuse. Self-esteem can apply to a specific attribute or globally. Psychologists usu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locus Of Control
Locus of control is the degree to which people believe that they, as opposed to external forces (beyond their influence), have control over the outcome of events in their lives. The concept was developed by Julian B. Rotter in 1954, and has since become an aspect of personality psychology. A person's " locus" (plural "loci", Latin for "place" or "location") is conceptualized as internal (a belief that one can control one's own life) or external (a belief that life is controlled by outside factors which the person can not influence, or that chance or fate controls their lives). Individuals with a strong internal locus of control believe events in their life are primarily a result of their own actions: for example, when receiving an exam result, people with an internal locus of control tend to praise or blame themselves and their abilities. People with a strong external locus of control tend to praise or blame external factors such as the teacher or the difficulty of the exam.Car ...

Psychological Assessment
Psychological evaluation is a method to assess an individual's behavior, personality, cognitive abilities, and several other domains. A common reason for a psychological evaluation is to identify psychological factors that may be inhibiting ''a person's ability to think, behave, or regulate emotion functionally or constructively.'' It is the mental equivalent of physical examination. Other psychological evaluations seek to better understand the individual's unique characteristics or personality to predict things like workplace performance or customer relationship management. History Modern ''psychological evaluation'' has been around for roughly 200 years, with roots that stem as far back as 2200 B.C.Gregory, R. J. (2010). Psychological testing: history, principles, and applications. (7th ed., pp. 1-29 inclusive). Boston, MA: Allyn & Bacon. It started in China, and many psychologists throughout Europe worked to develop methods of testing into the 1900s. The first tests focused o ...

Self-determination Theory
Self-determination theory (SDT) is a macro theory of human motivation and personality regarding individuals' innate tendencies toward growth and innate psychological needs. It pertains to the motivation behind individuals' choices in the absence of external influences and distractions. SDT focuses on the degree to which human behavior is self-motivated and self-determined. In the 1970s, research on SDT evolved from studies comparing intrinsic motivation, intrinsic and intrinsic motivation, extrinsic motives and a growing understanding of the dominant role that intrinsic motivation plays in individual behavior.e.g. Lepper, M. K., Greene, D., & Nisbett, R. (1973). ''Undermining children's intrinsic interest with extrinsic reward: A test of the "overjustification" hypothesis''. ''Journal of Personality and Social Psychology'', ''28'', 129–137. It was not until the mid-1980s, when Edward L. Deci and Richard Ryan (professor), Richard Ryan wrote a book entitled ''Intrinsic Motiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychological Testing
Psychological testing refers to the administration of psychological tests. Psychological tests are administered or scored by trained evaluators. A person's responses are evaluated according to carefully prescribed guidelines. Scores are thought to reflect individual or group differences in the construct the test purports to measure. The science behind psychological testing is psychometrics.Nunnally, J.C., & Bernstein, I.H. (1994). ''Psychometric theory''. New York: McGraw-Hill. Psychological tests According to Anastasi and Urbina, psychological tests involve observations made on a "carefully chosen ''sample'' mphasis authorsof an individual's behavior." A psychological test is often designed to measure unobserved constructs, also known as latent variables. Psychological tests can include a series of tasks, problems to solve, and characteristics (e.g., behaviors, symptoms) the presence of which the respondent affirms/denies to varying degrees. Psychological tests can include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
