J Family Med Prim Care 2020 Jul 30;9(7):3565-3573. Epub 2020 Jul 30.

Department of Physical Therapy, Rehabilitation Faculty, Iran University of Medical Sciences, Tehran, Iran.

Background: To cross-cultural adaptation, test-retest reliability, construct validity of the Persian version of avoidance endurance questionnaire (AEQ) in Iranian subjects with chronic nonspecific neck pain (CNSNP).

Objective: The AEQ differentiates endurance responses [ER; positive mood scale (PMS), thought suppression scale (TSS), pain persistence behavior scale (PPS), humor/distraction scale (HDS), and behavioral endurance scale (BES) from fear-avoidance responses (FARs; anxiety/depression scale (ADS), catastrophizing scale (CTS), helplessness/hopelessness scale (HHS), avoidance of social activities scale (ASAS), and avoidance of physical activities scale (APAS)].

Methods: One hundred and thirty persons with CNSNP took part in this psychometric study. The translation process was done by Beaton guideline. Test-retest reliability and internal consistency were presented by intraclass coefficient (ICC) and Cronbach's alpha, respectively. The construct validity was measured by the correlation between AEQ subscales and the Short-form health survey (SF-12), visual analog scale (VAS), fear-avoidance beliefs questionnaire (FABQ), pain catastrophizing scale (PCS), Tampa scale for kinesiophobia (TSK), and neck disability index (NDI).

Results: The Cronbach's alpha of all FAR and ER subscales was more than 0.7, and ICCs of all FAR subscales were more than 0.8 and ICCs of ER subscales were reported between 0.59 and 0.86. The correlation between FAR subscales and TKS, FABQ, FABQ.PA, FABQ.W, NDI, PCS, and VAS were the limit between -0.239 and 0.199, and the association between ER subscales and the abovementioned questionnaires was the limit between 0.179 and 0.644.

Conclusions: The Persian version of AEQ showed acceptable reliability (test-retest, internal consistency) for FAR and ER, and also the construct validity was acceptable. The Persian version of AEQ had acceptable psychometric properties, thus it is a good instrument to identify fear avoidance and ERs of the pain.

Underlying pathway of factors leading to mental health in Iranian young adolescents: A structural equation modeling.

J Res Med Sci 2020 24;25:75. Epub 2020 Aug 24.

Pediatric Neurorehabilitation Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.

Background: The present study aimed to provide a field-tested model of constituting factors affecting mental health in young Iranian adolescents.

Materials And Methods: In this cross-sectional study, a conceptual model was proposed based on an extensive literature review. A total of 254 young adolescents aged 11-14 years were recruited from north, south, east, and west regions of Tehran megacity by a random cluster sampling procedure, of whom 244 adolescents participated. The adolescents and their mothers altogether completed eight questionnaires pertaining to the proposed conceptual model: (1) Strengths and Difficulties Questionnaire (SDQ), (2) Childhood Experience of Care and Abuse Questionnaire, (3) Child Exposure to Domestic Violence Scale, (4) Drug Abuse Screening Test-10, (5) Baumrind Parenting Style Questionnaire, (6) Conflict Behavior Questionnaire, (7) General Health Questionnaire-28, and (8) Garmaroodi Socioeconomic Status Questionnaire. The statistical analysis was performed using structural equation modeling.

Results: This study demonstrated that parent mental health ( = -0.111), experience of father's care ( = -1.112), conflict with mother ( = 0.309), conflict with father ( = 0.135), and exposure to domestic violence ( = 0.217), as well as age ( = 0.93) and gender ( = 0.139), had direct effect on adolescent mental health (all < 0.05). Further, the results showed that exposure to domestic violence and conflict with mother had the greatest direct impact on adolescent mental health among all other family-related factors, followed by conflict with father and parent mental health. Conflict with mother and conflict with father also affected adolescent mental health indirectly through experience of domestic violence and had a mediating effect for the influence of several other factors on adolescent mental health, thus playing an important role in the pathway leading to young adolescent mental health status in the Iranian population.

Conclusion: Overall, the final model proved to be fit and the factors constituting the final model were able to predict 88% of the variations in the mental health of Iranian adolescents. This model can guide clinical psychologists, psychiatrists, and other mental health workers in a more realistic and effective prevention or treatment planning for their young clients. Moreover, it may help in arriving at a comprehensive preventive policymaking for mental health policymakers.

The Psychometric Properties of the Drug Abuse Screening Test.

Addict Health 2020 Jan;12(1):25-33

Pediatric Neurorehabilitation Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.

Background: Substance abuse is a critical problem in most countries, especially in developing ones. Early detection is the pre-requisite of early control, for which reliable and valid tools are required. In the present study, we aimed at measuring the psychometric properties of the 10-item Drug Abuse Screening Test (DAST-10) in Iranian individuals.

Methods: After translation and back-translation of the questionnaire, 244 adults were recruited from Tehran Megacity, Iran, and completed the questionnaires. Participants were recruited by a multistage randomized cluster sampling method. Reliability was determined by Cronbach's alpha. Also, construct validity was evaluated using confirmatory factor analysis (CFA) and exploratory factor analysis (EFA).

Findings: The internal consistency using Cronbach's alpha coefficients for the total score of the Persian version of DAST-10 was 0.93. EFA evoked only one factor for DAST-10. The CFA for 1-factor models for DAST-10 indicated an acceptable fit for the proposed models.

Conclusion: The results prove desirable reliability and validity of the Persian version of the DAST which can be utilized as a screening instrument for drug abuse among Iranian adults.

Translation, cross-cultural adaptation and factor analysis of the Persian version of ankle instability instrument.

Med J Islam Repub Iran 2018 1;32:79. Epub 2018 Sep 1.

Department of Orthopedic Surgery, Iran University of Medical Sciences, Tehran, Iran.

Ankle Instability Instrument (AII) is a questionnaire for determination of ankle stability status. The aim of this study is to cross-culturally translate and investigate the reliability and validity of AII in a sample of Persian-speaking Iranians, suffering from ankle sprain. One hundred twenty persons with a history of ankle sprain were recruited in the study. All participants completed the Persian version of Ankle Instability Instrument, Cumberland Ankle Instability Tool (CAIT), Foot and Ankle Ability Measure (FAAM) and Foot and Ankle Outcome Score (FAOS) at the baseline. Out of them, 60 randomly selected subjects completed the questionnaires once more, one week later. Face validity, Test-retest reliability, internal consistency, standard error of measurement, minimal metric detectable change, spearman's correlation coefficient and confirmatory factor analysis of AII measured. We used Lisrel v 8.80 software with significant level of p<0.05. Persian version of AII is clear and unambiguous and its qualitative face validity was confirmed in the pilot study on the 20 subjects with a lateral ankle sprain. The interclass correlation coefficient, Cronbach's alpha, standard error of measurement and minimal metric detectable change were 0.93, 0.87, 0.81 and 2.25 (95% confidence interval, 0.85-0.96). The Spearman correlations coefficients between AII, and CAIT, FAAM and FAOS measures were 0.91, 0.71 and 0.69 respectively. The original three factor structure of AII was replicated based on the confirmatory factor analysis. Which showed an adequate fit of the model to the data and goodness-of-various fit indices. The Ankle Instability Instrument Persian Version (AII-PV) is a reliable and valid measure for assessing the ankle stability status.

Mastery Motivation in Children with Cerebral Palsy (CP) Based on Parental Report: Validity and Reliability of Dimensions of Mastery Questionnaire in Persian.

Mater Sociomed 2018 Jun;30(2):108-112

Pediatric Neurorehabilitation Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.

Introduction: The present study aimed to investigate validity and reliability of Persian Dimensions of Mastery Questionnaire (DMQ18) in children with cerebral palsy.

Material And Methods: The original version was carried out through back translation into Persian, and then the construct validity was assessed by confirmatory factor analysis; and reliability was evaluated through Cronbach's alpha (n=230). Intra-class correlation coefficient (ICC) was used for test retest reliability (n=32).

Results: 230 parents (155 (67.4%) mothers and 75 (32.6%) fathers) of children and adolescents with CP with an average age of 126.99±24.59 months participated in the present research. Non-questions excluded from the confirmatory factor analysis, and thus all questions remained. Internal consistency reliability and total score were acceptable in all domains (higher than 0.70) except for negative reactions, sadness/shame (Cronbach's alpha of 0.414). Intra-class correlation coefficient of all domains and total score were significant (p<0.001).

Conclusion: DMQ18 (parental report) was valid and reliable for children with cerebral palsy. It also provided valuable information about different aspects of motivation in CP children according to their parents' opinion, and thus it can be used in clinical interventions.

To cross-culturally translate the Identification of Functional Ankle Instability (IdFAI) questionnaire into Persian and to assess its psychometric properties and factor structure. The Persian version of IdFAI questionnaire was prepared after a forward-backward translation and cultural adaptation process. One hundred and twenty patients with a history of lateral ankle sprain completed the Persian version of this questionnaire and the Cumberland Ankle Instability Tool (CAIT), Foot and Ankle Ability Measure, Foot and Ankle Outcome Score, Fear Avoidance Belief questionnaire and the Tampa Scale of Kinesiophobia in the first test session. Afterwards, 60 randomly selected patients completed the questionnaires in the second session. Psychometric testing which included test-retest reliability, internal consistency, standard error of measurement (SEM) and minimal metric detectable change (MMDC), weighted kappa coefficient and construct validity were performed using Spearman's correlation coefficient and confirmatory factor analysis of the three-factor structure of the IdFAI. The interclass correlation coefficient, Cronbach's alpha, SEM and MMDC were 0.91, 0.95, 2.43, and 6.73 (95% confidence interval, 0.86-0.95) for the IdFAI, respectively. The repeatability of all the questions after one week was rated good to excellent (kappa = 0.60-0.93,  < 0.001). The IdFAI total score had strong correlation with CAIT measure, but had moderate correlation with other questionnaires. The results of factor analysis showed an adequate fit of the model to the data and goodness-of-various fit indices. The Persian version of IdFAI is a reliable and valid tool to identify patients with functional ankle instability which have a history of ankle sprain. Its original three-factor structure was replicated in this study. Implications for Rehabilitation The Persian version of the Identification of Functional Ankle Instability (IdFAI) questionnaire is a reliable and valid instrument in order to identify Iranian patients with functional ankle instability in both clinical practice and research. The Persian IdFAI questionnaire may be considered as a standardized clinical instrument that can be used to classify degree of ankle instability in Iranian Persian-speaking people with a history of lateral ankle sprain. People with a history of ankle sprain can be assessed using IdFAI questionnaire before and after rehabilitative interventions in an attempt to determine any change in their degree of ankle instability over time.

Reliability and Validity of the European Child Environment Questionnaire (ECEQ) in Children and Adolescents with Cerebral Palsy: Persian Version.

Children (Basel) 2018 Apr 9;5(4). Epub 2018 Apr 9.

Pediatric Neurorehabilitation Research Center, University of Social Welfare and Rehabilitation Sciences, 1985713834 Tehran, Iran.

The aim of this study was to assess the reliability and validity of the Persian version of the European Child Environment Questionnaire (ECEQ) in the Iranian context. In total, 332 parents (20.2% fathers and 79.8% mothers) of children and adolescents with cerebral palsy (CP) with an average age of 12.33 years (min 7.08 to max 18.08) from three provinces in Iran participated in the study. The original version of the questionnaire was translated and back-translated. Confirmatory construct validity was assessed by factor analysis and reliability was evaluated by Cronbach's alpha ( = 332) and after two weeks' test-retest reliability ( = 51) using an intraclass correlation coefficient (ICC). Eleven questions were dropped as they did not fit well into domains in the Persian version ( > 0.05). Cronbach's alpha and intraclass correlation coefficient in all domains and overall were acceptable (higher than 0.70) and significant ( > 0.05). The Persian version of the ECEQ is suitable for assessing the needs and availability of environmental factors and is reliable and valid for children with CP, as reported by their parents.

Comparing Levels of Mastery Motivation in Children with Cerebral Palsy (CP) and Typically Developing Children.

Med Arch 2018 Feb;72(1):41-45

Department of Physiotherapy, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.

Introduction: The present study aimed to compare motivation in school-age children with CP and typically developing children.

Material And Methods: 229 parents of children with cerebral palsy and 212 parents of typically developing children participated in the present cross sectional study and completed demographic and DMQ18 forms. The rest of information was measured by an occupational therapist. Average age was equal to 127.12±24.56 months for children with cerebral palsy (CP) and 128.08±15.90 for typically developing children. Independent t-test used to compare two groups; and Pearson correlation coefficient by SPSS software applied to study correlation with other factors.

Results: There were differences between DMQ subscales of CP and typically developing groups in terms of all subscales (<0.05). The lowest motivation scores of subscales obtained in gross motor persistence (2.4870±.81047) and cognitive-oriented persistence (2.8529±.84223) in children with CP. Motivation was correlated with Gross Motor function Classification System (r= -0.831, P<0.001), Manual ability classification system (r=-0.782, P<0.001) and cognitive impairment (r=-0.161, P<0.05).

Conclusion: Children with CP had lower mastery motivation than typically developing children. Rehabilitation efforts should take to enhance motivation, so that children felt empowered to do tasks or practices.

Intratester and intertester reliability of the movement system impairment-based classification for patients with knee pain.

Man Ther 2016 Dec 5;26:117-124. Epub 2016 Aug 5.

Department of Physical Therapy, School of Rehabilitation Sciences, Iran University of Medical Sciences, Tehran, Iran.

Background: The methods to standardize the test items used for classification of patients with knee pain based on the movement system impairment (MSI) approach have been established. To our knowledge, no study has concentrated on establishing reliability for proposed classification for knee pain problems.

Objective: The aim of the study was to assess intra- and intertester reliability of the knee MSI classification in patients with knee pain.

Design: A cross-sectional methodological study.

Setting: Rasul Akram Hospital.

Participants: Ninety-six subjects with knee pain aged 18-65 years.

Methods: In order to examine intertester reliability, all three testers assessed the symptoms, signs and the MSI diagnosis of subjects with knee pain simultaneously. In order to assess intratester reliability, the procedure was exactly repeated after a one-week intersession period. Kappa values and percentages of agreement were calculated to analyze the reliability level.

Results: The kappa values for intra- and intertester reliability of the symptom items ranged from 0.83 to 1.00 and 0.00 to 0.83, respectively. For the sign items, the kappa values ranged from 0.18 to 1.00 and 0.00 to 0.82, respectively. Finally, the kappa values of intra- and intertester reliability for patients' classification judgments ranged from 0.66 to 0.71, and 0.48 to 0.58, respectively.

Conclusion: The results of the present study indicate that intertester reliability for the symptoms, signs and classification judgments of patients with knee pain based on the MSI approach seemed generally acceptable. However, for intratester reliability, lower levels of the system were observed, probably due to different pain levels or pain behavior between test and retest sessions.

Validation of the movement system impairment-based classification in patients with knee pain.

Man Ther 2016 Sep 2;25:19-26. Epub 2016 Jun 2.

Department of Physical Therapy, School of Rehabilitation Sciences, Iran University of Medical Sciences, Tehran, Iran.

Background: Categorizing patients with knee pain problems based on pathoanatomical sources has not proved to be the most effective method for directing physical therapy interventions. Movement system impairment (MSI) classification system may be an alternative in the assessment, diagnosis, and management of patients with knee pain. No previous study has been conducted to validate the proposed system in these patients.

Objective: To assess construct validity of the MSI classification system in patients with knee pain.

Design: A cross-sectional methodological study.

Setting: Rasul Akram Hospital.

Participants: One hundred eighty subjects with knee pain aged 18-65 years.

Methods: The MSI classification recognizes seven categories of knee pain problems based on the findings from the symptoms and signs assessment. Three physical therapists examined subjects with knee pain. A principal component analysis (PCA) was used to derive proposed categories. Eigenvalues and a scree plot were also used to determine the factor retention.

Results: Four factors related to three proposed categories were extracted from the PCA. Two factors were related to tibiofemoral rotation (TFR) category. The other two factors were related to proposed categories patellar lateral glide (PLG) and tibiofemoral hypomobility (TFHypo).

Conclusion: The results provided evidence for the construct validity of three (TFR, PLG, and TFHypo) of the seven categories proposed by MSI classification. In addition TFR was subcategorized into two groups which were named as tibial lateral rotation (TLR) and femoral adduction/medial rotation (FAdd/MR) in the present study.

Reliability of center of pressure measures of postural stability in healthy older adults: effects of postural task difficulty and cognitive load.

Gait Posture 2011 Apr 31;33(4):651-5. Epub 2011 Mar 31.

Department of Physical Therapy, Faculty of Rehabilitation Sciences, Tehran University of Medical Sciences, Tehran, Iran.

Postural instability is a major risk factor of falling in the elderly. It is well documented that postural control may decline while performing a concurrent cognitive task and this effect increases with age. Despite the extensive use of dual tasking in balance assessment protocols, a lack of sufficient reliability information is evident. This study determines the reliability of the postural stability measures in older adults, assessed under single and dual-task conditions and different levels of postural difficulty. Sixteen older adults completed quiet stance postural measurements at three levels of difficulty (rigid surface-eyes open, rigid surface-eyes closed, and foam surface-eyes closed), with or without performing a concurrent backward counting task, in two sessions 1 week apart. Force plate data was used to calculate center of pressure (COP) parameters including mean velocity, phase plane portrait, area (95% confidence ellipse), standard deviation (SD) of amplitude, and SD of velocity. Intraclass correlation coefficient (ICC), standard error of measurement (SEM), coefficient of variation (CV), and minimal metrically detectable change (MMDC) were calculated for each COP measure in all test conditions. Mean velocity, total phase plane, phase plane in ML direction, and SD of velocity in ML direction were the most reliable COP measures across all test conditions. ICC values were consistently higher in ML direction compared with AP direction. In general, velocity-related COP measures in ML direction showed to be highly reliable. Further research may explore the predictive and evaluative value of these COP parameters.
