The present study aims to determine the diagnostic validity of the fifth version of the Wechsler Children's Intelligence Scale in students with attention deficit disorder in Tehran cities. The method of the current research is methodological it is psychometric. The statistical population included all the students in first, second, and third grades of the cities of Tehran province in the academic year of 1401-1402, who were under educational-therapeutic intervention in counseling and psychology centers of these cities as students with attention deficit. The research sample group included 120 students with attention deficits in the study with a non-random sampling method. The Wechsler Intelligence Scale for Children-Fifth Edition (2015, WISC-V) was the research instrument. The data collected using descriptive statistics indices (central tendency indices and dispersion indices) scatter diagram method (Davis method) and confidence interval method were used to check the diagnostic validity. The research findings showed that all tests of "Working memory" and "processing speed" scales have diagnostic validity. Therefore, tests of " Working memory" and "processing speed" scales can distinguish students with attention deficit disorder from normal students.

This study was conducted with the aim of determining the diagnostic validity of the fifth edition of Wechsler's intelligence scales for children in the neuropsychological characteristics of students with learning disabilities in Tehran. The present study was subset of methodological studies. The number of 400 people with learning disabilities who were selected using a targeted and available sampling method and 400 normal people who were randomly selected from among all male and female students between the ages of 7 and 11 in Tehran in the academic year of 2018-2019. In line with the purpose of the research, the fifth edition of the Wechsler Children's Intelligence Scales (2014) was used. The collected data were analyzed using logistic regression analysis and SPSS software (Version 23).The study finally revealed that vocabulary and information tests (from verbal comprehension index), Block design with time point (from Visual-spatial index),arithmetic (from fluid reasoning scale), number span (direct), number span (reverse), picture span, letter-digit sequencing and letter-number sequencing (from working memory scale),and coding, cancellation (random), cancellation (structural), (from Processing speed index), had diagnostic validity.The fifth version of the Wechsler IQ Scales for children has diagnostic validity in the neuropsychological characteristics of students with learning disabilities and can distinguish students with learning disabilities from normal students.

The purpose of this research was to examine the diagnostic validity of Reynolds Intellectual Assessment Scale (2nd edition) in pre-school students with attention deficit-hyperactivity/impulsive disorders in Islamshahr City. The population included pre-school students of Islamshahr city who came to counseling centers. The sample consisted of 120 pre- school students with 60 students with attention deficit-hyperactivity/impulsive disorders who were selected through targeted sampling and 60 normative students who were selected by systematic random sampling. The research is a narrative study examining diagnostic validity as a psychometric attribute. In order to analyze the data, after descriptive analyses, through scatter plot (with emphasis on Davis) and confidence intervals, attention deficit-hyperactivity/impulsivity of the Reynolds Intellectual Assessment Scale (2nd edition) was examined. The findings indicated that the scale of "fluid intelligence" and "processing speed" are the most important diagnostic criterion for attention deficit-hyperactivity/impulsive; therefore, the second version of the Reynolds Intelligence Assessment Scale has a diagnostic validity and can predict students with attention deficit-hyperactivity/impulsive disorders.

The purpose of this study was to investigate Learning disability diagnostic validation by Woodcock-Johnson III Tests of Cognitive Abilities in Ahvaz city. Statistical Society this study includes all male and female students with learning disabilities from the first to fifth grade of elementary school in Ahvaz. In the academic year 2012-2013, from the state and non-governmental centers, the individual learning problems of the city received special educational-therapeutic services. The research sample consisted of 60 students with learning disabilities who were selected through purposeful sampling. For data collection was completed the fourth edition of the Wechsler Intelligence Scale and Scaled cognitive abilities, Woodcock-Johnson III version was used. The descriptive study design was of similar causal type. The information gathering method was fieldwork and individual and face-to-face method; Direction data analysis descriptive statistics methods such as frequency, percentage, mean, standard deviation were used. The results of the research showed that student intelligence unable to learn "active memory" and "total scale" Less than usual students there is also a significant difference between the similarities, vocabulary, understanding, information, Reasoning word, image Concepts, Number capacity, Number sequence -Character and symbolism. There are equal learning scores in learning disabilities and the factors of similarities, vocabulary, understanding, information,  reasoning word, Image concepts, number capacity,  number sequence - letter and symbolizing in diagnosis, students with learning disabilities have diagnostic validity.

This research   has been conducted with this goal to determine the diagnostic validity of the   new version of Tehran- Stanford- Binet for students with learning   disabilities. The statistical population consists all students with learning   disabilities who have been   referred   to Amol’s center of learning disabilities in the semester 1393- 1394. The   sample size contained 60 students who were selected by purposive sampling. To   collect data for this research the new version of Tehran-Stanford-Binet has   been used. In order to analyze the data and to determine the validity of   diagnostic instrument, diagram of the distribution and the confidence   interval method, and Composite has been used. The results showed that this   scale in the areas of knowledge, working memory and quantitative reasoning   has a little bit of a good diagnostic validity. Considering this fact that   subtests were low in students with learning disabilities, we can conclude   that these three indicators have the required predictive power, and with an   emphasis on the average of the constituent elements of nonverbal Domain of   Tehran-Stanford-Binet’s IQ test it was determined that among the factors,   verbal working memory with (5/08), has the lowest average.

The purpose of this Survey was to the diagnostic validity Scale version of the new intelligence Tehran - Stanford-Binet in students with learning disabilities in the Gilan. The research population included all boy and girl students with learning disabilities aged 6 to 13 years who have learning disorders centers in Gilan province, including the cities visited Roodsr, Langrood, … academic year 93- 1394, the sample consisted of 60 students with learning disabilities who were selected using purposive sampling. The research in the area of validity of the diagnostic validity studies with an emphasis on the methodology of psychometrics Statistical Data analysis in two separate and consecutive descriptive analysis (with emphasis on intelligence Sacle new versions of Tehran-Stanford - Binet) associated with the reliability of diagnostic analysis, scatter plot method (with emphasis on Davis), the confidence intervals and take advantage of the Composite of learning disability (IQ Scale Tehran-Stanford-Binet new version) was used. The findings indicate that the verbal and total IQ, verbal knowledge and knowledge of non-verbal, non-verbal working memory and verbal working memory, verbal and quantitative reasoning, quantitative reasoning, nonverbal learning disorders can be named as the most important criterion. Because of defects in these criteria in samples examined in this research there. StanfordBinet intelligence Scale new versions Tehran, so the diagnostic validity and can identify students with learning disabilities.

The main purpose is to identify diagnostic validity fourth edition and an Integrated version of the Wechsler Intelligence scales children (WISC-IV) with attention deficit disorder in children. Psychometric studies is the research within that subset is Methodology research methods. Population included all male and female students in elementary schools in Tehran in the academic year 1393-94, form the sample size was selected using purposive sampling method. Instruments measured in this study is the fourth edition and an additional version of the Wechsler Intelligence Scale for children who have good validity and reliability of an important loss. To determine the diagnostic validity of the scatter plot (by Davis), and axial combined (composit) confidence interval method is used. Using the plot of the fourth edition showed that significant differences in the tests complete (Integrated), the direct Digit span, Digit span reverse, total Digit span, Letter-number sequence, Arithmetic, Coding, symbol search, accidental Cancelling, structure Cancelling and the materials it was determined that significant differences in test version Block Design with time bound, Elitorn Mazes with time bound, Elitorn Mazes without time bound the visual Digit span of Direct, visual Digit span of reverse, the Letter sequence (Rythmic), the Letter sequence (NonRythmic), Letter-Number sequence , the Arithmetic process (part a), process Arithmetic (part b) and copy code between the scores of normal children and Hyperactivity - attention deficit there and these factors can be diagnosed Hyperactivity - attention deficit with normal children. Also, by using the method specified confidence interval fourth edition was also a significant difference between working memory (69/52), processing speed (68/45) and scale (79/87) and complementary version is a significant difference between the memory active (67/65), processing speed (66/84) with an average theoretical (population norm) in children Hyperactivity - attention deficit there, while axial combined (composit) with the Wechsler intelligence scale for children to recognize students Hyperactivity - attention deficit not have diagnostic validity.

This study evaluated the psychometric properties of the new version Tehran Intelligence LaboratoryStanford-Binet centers of learning disabled students learning disorders related to special education was discussed. Given the sample size of 523 patients from all centers of learning disabilities, to evaluated the validity using Cronbach alpha, test-retest and split-half, and the error of measurement -measurement was obtained. Also, in order to validate the diagnostic validity studies for three reading ability, and focus were used to calculate sensitivity coefficients were calculated in the interpretation of diagnostic validity. In addition, confirmatory factor analysis was used to examine the internal structure and psychometric findings survey indicated that the Factor validity of the instrument has been validated and this instrument as a Creditand valid and reliable tool for screening and diagnosis of learning disabilities.

Acquiring meaning in life is one of the effective factors in psychological problems and disorders. The purpose of this research was investigating discriminative and constructs validity of Meaning in Life Questionnaire. 296 students at university of Tarbiat Moallem in Azarbayjan، Iran took part in this study. Meaning in Life Questionnaire (MLQ) and General Health Questionnaire (GHQ) were used for data collection. Confirmatory factor analysis (CFA) was used to ensure construct validity، and a hierarchical discriminative function analysis was used for discriminative validity analysis. Confirmatory factor analysis resulted in a related two-factor model with acceptable fitness indices. The MLQ also showed a high ability in discriminating healthy individuals. Nevertheless، the instrument did not have an adequate accuracy in screening people at risk with regard to an initial grouping based on scores of GHQ. The findings also showed that females had a higher mean score in MLQ in comparison with male participants. The construct validity of MLQ is acceptable for a sample of Iranian students though its discriminative validity was much more accurate in diagnosing healthy individuals than people at risk

The purpose of this study was to investigate the diagnostic validity of MCMI-III (Millon,) Scales in an Iranian population. The diagnostic validity of MCMI-III Scales was examined among psychiatric patients. Using operating characteristics (prevalence, sensitivity and specificity) of MCMI-III Scales, the predictive powers (positive, negative and overall) of the Scales was calculated. The results showed very good diagnostic validity for all MCM-III scales. Findings suggest MCMI-III Scales were found having high PPPs, NPPs and OPPs. The PPPs ranged from. to, and The NPPs ranged from to also OPPs ranged from to for all scales. Thus MCMI-III is a valid inventory and it can be used for Diagnosis personality disorders and clinical syndromes.
