Assessment of auditory processing in children is performed via special tests with confirmed sensitivity. For any adapted or developed test, there should be evidences to demonstrate acceptable test-retest reliability. Recently, two dichotic listening and two recognition of speech-in-noise tests of auditory processing have been developed in Persian language. The present study aimed to assess test-retest reliability of these tests in normal children.

The present observational and analytic study was performed on 40 children, aged 6-12 years old, selected from two elementary schools in Tehran. Inclusion criteria were right-handedness, normal peripheral hearing sensitivity (

The mean score of FARDIN and PARWIN did not show a significant difference between tests and retest sessions. Dichotic listening tests scores showed a significant improvement in retest session. Intra-class correlations for tests of recognition of speech-in-noise and dichotic listening tests were 0.6-0.65 and 0.6-0.9, respectively. FARDIN and PPCW showed higher absolute reliability compared with PARWIN and PPCS tests, respectively.

Although children' performance for dichotic tests in retest session was slightly better, it seems that auditory processing tests used in the current study have adequate test-retest reliability in normal children.

Many people suffer from chronic nonspecific low back pain among other musculoskeletal disorders during their life time. There is a close relationship between low back pain and one’s physical activity type. Therefore, it is important to have a satisfactory measurement tool to identify and measure the type and rate of physical activity and give some information about type and rate of physical activity to patients and therapists. The aim of this research was to investigate the face validity and test-retest reliability of Persian translation of "Baeck physical activity questionnaire" in patients with chronic nonspecific low back pain.
Baeck Physical Activity Questionnaire was translated to Persian in accordance with the standards set by the International Quality of Life Assessment (IQOLA) translation protocol with the help of an expert panel. Face validity of the final translation was investigated by both qualitative and quantitative methods. Pearson’s correlation and ICC were used to measure the test retest reliability of the test.
Experts’ opinions were sought as to the wording and clarity of each statement in the instrument. In addition, the opinions of the target population (N=20) was asked as to the face validity of each item. A reliability of 0.85 calculated through ICC and 0.90 calculated through Pearson Correlation Coefficient confirmed the test-retest reliability of the instrument.
Persian translation of Baeck Physical Activity Questionnaire enjoys an acceptable face validity and test-retest reliability in patients with Low Back Pain.

Background and Cerebral palsy is a common disorder in children leading to their dysfunction in many aspects. Therefore, to provide appropriate treatment plan that could improve the function of these children, a valid assessment tool is needed. Pediatric Evaluation Disability Inventory (PEDI) is designed to evaluate the performance of children with disabilities in three dimensions: self-care, mobility, and social function. The purpose of this study was to evaluate the reliability of the Persian version of PEDI in children with cerebral palsy aged 3 to 9 years old. In this study, 75 participants were selected by convenience sampling. Information was collected using demographic questionnaire and Gross Motor Function Classification System (GMFCS). The parents were interviewed and PEDI was completed. After two weeks, in order to evaluate the reliability of the test-retest, 22 parents were re-interviewed. Internal consistency was examined by Cronbach's alpha, and the reliability of the test-retest was assessed by intra-class correlation coefficient (ICC). In examining the internal consistency, Cronbach's alpha was found to be high (0.94-0.98).The results of test-retest reliability of the functional skills and caregiver assistance scale were excellent (0.96-0.97). Also, the results of test-retest reliability in modification scale were excellent in self-care and social performance (0.99 and 1, respectively) and good in mobility dimension (0.66). This study proved the internal consistency and test-retest reliability of the Persian version of PEDI in evaluating the performance of Persian-speaking children with cerebral palsy. Therefore, PEDI could be applied in research and clinical settings for evaluation of children with cerebral palsy in Iran.

Aim and Upper extremity functional problems are the most common disorder which follow cerebral palsy arise. children have difficulty due to neuromuscular problems such as cerebral palsy، this children have less opportunity to receive information from environment and to understand the impact their function on environment and thus their experience decreases in activities. Hand function is the necessities of daily life in all people especially cerebral palsy. Due to amount of hand function disabilities and its importance in cerebral palsy chidren، we decided to examine the reliability of Jebsen-Taylor Hand Function test in cerebral palsy children. Methods & Materials: study is non-experimental and descriptive analysis. In this study، 33 children with diplegia cerebral palsy from 8-12 years old were selected from special school of Tehran through non-probability sampling and from both sexes. In this study، hand function was assessed with jebsen-taylor test by the simultaneous presence of two expert (inter-rater reliability). Then a week after initial assessment، one experimenter did a re-assessment (intra-rater reliability). This reliability was assessed by Using the intraclass correlation coefficients (ICC) The results of this study was showed high correlation in inter-rater (P=0/001 و ICC=0/998) and intra-rater reliability (P=0/001 و ICC=0/95). the results showed that inter-rater and intra-rater reliability was high in diplegia cerebral palsy. So this test is recommended as a reliable clinical tool to assess the hand function of these children.

Down syndrome is considered as one of the most important causes of disability. In children with Down syndrome, compliance with poor motor coordination has a considerable effect on different motor skills including dexterity. Purdue Pegboard test is one of the tools used in occupational therapy to assess fine motor skills of upper extremity. The purpose of this study was to determine the test-retest reliability and practice effects of the Purdue Pegboard in children with Down syndrome. Twenty-four children with Down syndrome aging 7-14 (mean:9/7±2/7) of both sexes were non-randomly selected from rehabilitation clinics and hospitals of Tehran. A demographic questionnaire was used for documenting participant s general data and the Purdue Pegboard test and a timer were used to determine the reliability. Each subtest was administered three times in a row. The time interval between test and retest was one week. The relative reliability in repeated measures was above 80% in different items of Purdue Pegboard test in single and mean of testes, thus it indicates an optimum reliability. The absolute reliability was lower than 10% of maximum obtained scores at each subtest in one and three trial of test that indicates acceptable errors of measurement. The results of the present study indicate that Purdue Pegboard test is enough reliable in one and three trials for evaluating a manual dexterity of children with Down syndrome.
