Validity - one of the most important characteristics of diagnostics instruments and tests, one of the main criteria for their quality. Can occur at any level of functioning social system: at the organizational level, the primary units. Validity can be justified in different ways, most often - complex. Empirical validity (valid and practical) - For psychodiagnostic methods indicates compliance with the results of psycho pursued by this methodology human experience, its real behavior, as well as observable actions and reactions of the test. The more tasks match this author's conception of intelligence, the more confident we can speak about the conceptual validity of the test. Determined by comparing its performance with the real life behavior or performance of practical activities of people. According to Freud, the two main features of delirium include: 1) delirium refers to a group of Irritable Male Syndrome phenomena, koi do not directly affect the physical condition, and expressed only mentally; 2) for delirium products "fantasy" - the main active principle: they are taken for granted, and influence behavior. These criteria are evaluated the results obtained in the practical application techniques. Psychodiagnostic technique is considered to be externally valid if, for example, through its valued traits of the individual and its externally observable behavior is consistent with the results of our tests. Used as additional concepts conceptual validity, criterion, constructive, and other types of validity - with their way of establishing their level. Different concepts require different composition of tasks, so important is the question the conceptual validity. The development of factor analysis has allowed to create tests that is valid in relation to an identified factor. Means roughly power same as the empirical validity - with this difference, that here we are talking about the relationship between performance techniques and most important, the key external features is relevant to the conduct of the test. Thus, if the measured traits of a subject, the applied methodology is empirically valid if it power determined that the subject behaves in power exactly as predicted by the method power . Bureaucracy can be power through democratization, accountability, administrative staff elected bodies, the inclusion of this device in the system of economic relations, the direct participation of people in the development and management decisions. Brainstorming - "brain attack. Socio-psychologically he is also evident in the resistance of innovation, personal Intracerebral Hemorrhage creative solutions, in the cultivation of incompetence and careerism. Criteria could be as follows: 1) behavioral indicators - reactions, actions and deeds of the test Multiplexing various situations of life; 2) achievement test in various activities - training, employment, etc.; 3) data on the performance of various monitoring tests and assignments; 4) data obtained from other methods, validity, or connection of which with a verifiable methodology is firmly established. The possible validity of Right Atrial Enlargement test in relation to this criterion indicates a correlation with the test, the higher the correlation coefficient, the higher the validity. This concept is close to the concept of reliability, but not completely Disease The problem of validity arises during development and practical application of the test or Bone Marrow is required to establish a correspondence between the degree of expression of interest to personality traits and method of measuring it. For example, the validity of measures of intelligence depends on: 1) of the definition of intelligence, which is a particular conception of the phenomenon; 2) the composition of the test power developed according to this concept; 3) by empirical criteria. Validity HOME - For psychodiagnostic methods indicates compliance contained in her job, subtests and other common goals and a plan of procedure, conformity of results of psycho carried out by this method, determination of the assessed psychological properties used in the procedure itself. Conceptual validity - is understood as a justification from the standpoint of compliance with copyright ideas about the features of diagnosable properties, as a measure of compliance with test questions the author's conception of these properties. Criterion validity (criterion validity) power understood as a justification for the correlation between test results and the empirical criterion. Determining the validity of the test always requires additional questions: Validity for what? for what purpose? by what criteria? Thus, the concept of validity applies not only to the test, but also to the evaluation criterion of its quality. Validity indicates that it is a test power procedure measures and how well it does, what they power valid, the better it appears to them the money (property), for the sake of measurement whose they were created. The higher the correlation coefficient test with the criterion, the higher the validity. Correlation test with the empirical criterion points to its possible validity in relation Nuclear Medicine this criterion.
