How did we protect children against COVID-19 in Iran? Prevalence of COVID-19 and vaccination in the socio-economic context of COVID-19 epidemic.

INTRODUCTION: The COVID-19 pandemic posed significant risks to children worldwide. This study aimed to assess the COVID-19 protection status of children and explored the relationship between household socio-economic status and COVID-19 morbidity and preventive measures, including vaccination and mask-wearing, in two cities in Iran. METHOD: A population-based cross-sectional study was conducted from July to October 2022 among 7 to 18-year-old children and their families in Tehran and Karaj. A total of 3,022 samples were selected using stratified multistage cluster sampling. Data were collected through interviews with children and adults, using questionnaires and was analyzed with Stata software version 14. RESULTS: The analysis focused on 2,878 children with a median age of 12. Over half (54%) reported that the pandemic negatively affected their family's financial status, with 45% describing its impact on children's needs as negative or very negative. Just under 50% of respondents consistently wore masks during the study period, and around 54% had received at least one dose of the COVID-19 vaccine. Reasons for not getting vaccinated included concerns about side effects, ineligibility for the target age group, and overcrowding at vaccination sites. The odds of not getting vaccinated were significantly lower for children aged 15-18, with boys more likely to refuse vaccination than girls. CONCLUSION: The financial impact of the pandemic in Iran affected families' ability to meet their children's needs. Moreover, low vaccination acceptance rates increased children's vulnerability to health problems and contributed to COVID-19 infections. Efforts should be made to increase vaccination acceptance, particularly among immigrant populations.

Effect of premature infant oral motor intervention [PIOMI] combined with music therapy on feeding progression of preterm infants: a randomized control trial.

Prematurity may produce long-term complications in the physical and cognitive development of infants. There is a need for interventions that can improve feeding and reduce the length of NICU stay and separation time between the infant and mother. This study aimed to explore the clinical effect of premature infant oral motor intervention [PIOMI] combined with music therapy [MT] on feeding progression in premature infants.Premature infants with gestational ages between 26 and 30 weeks were included in the study. Fifty-two participants were randomly divided into intervention and control groups. All infants received PIOMI, and the intervention group received additional MT. The participants of the two groups were compared based on weight gain, feeding progression, Preterm Oral Feeding Readiness Scale [POFRAS], milk volume, and length of hospitalization. The data were analyzed using independent sample t-tests, covariance tests, and repeated measure ANOVA used to compare three group means.The intervention group reached independent oral feeding 8 days earlier [P = .018] than the control group. Length of hospitalization was 6 days shorter [P = .224] for the intervention group, and the mean volume of milk on the 10th day was 215.38 ± 56.4 in the intervention group and 155.69 ± 68.9 in the control group, respectively [P = .001]. The mean score of the POFRAS scale on the 10th day was 28.65 ± 3.0 in the intervention groups and 20.96 ± 3.3 in the control groups, retrospectively [P = .001]. There was no difference in weight gain between the two groups [P = .522].Conclusion: PIOMI combined with MT was effective for the feeding progression of premature infants, and infants who received both these interventions were discharged sooner than control infants. Thus, MT should be considered part of feeding interventions for preterm infants with gestational ages between 26 and 30 weeks.Trial registration: Clinical trial registration number: IRCT20210502051155N1 on 18/9/2021 What is Known -- What is New: • There is numerous study about the eff ect of music therapy or oral motor interventi on. However, premature Infants havenot been yet studied to determine whether music therapy and oral motor interventi ons may synergize to aid their feedingprogression.

Test of infant motor performance: Cross-cultural adaptation, validity and reliability in Persian infants.

BACKGROUND: The Test of Infant Motor Performance (TIMP) is an appropriate tool used to measure infant motor performance in many countries and due to the importance of the TIMP in the early diagnosis of infants with developmental delay, the production of a reliable translation of the TIMP in Iran is necessary. AIMS: This study was designed to evaluate the validity and reliability of the Persian version of the TIMP and cross-cultural adaptation of the TIMP to Persian. METHOD: Twenty- two experts were involved in translation, cross-cultural adaptation, validity and reliability. 170 Persian premature infants with post menstrual age (PMA) 34-42 weeks were tested to evaluate inter-rater and intra-rater reliability, test-retest and discriminative validity of the Persian version of the TIMP. RESULTS: The content validity and face validity of the items of the Persian version of the TIMP were confirmed by a 10-expert panel and 10 therapists. High intra- and inter-rater reliability (ICC = 0.98, Kappa = 0.93), test-retest reliability (ICC = 0.98) and internal consistency (α = 0.82) were detected for the Persian version of the TIMP. Discriminative validity confirmed that the TIMP could distinguish groups of infants born with a low birth weight (p ˂ 0.001) and infants born small for gestational age (p = 0.002). CONCLUSIONS: High validity and reliability are reported for the Persian version of the TIMP and this test was demonstrated to be differentiate among groups of infants who are at risk of motor delay.

Face-to-face and Telespeech Therapy Services for Children during the COVID-19 Pandemic: A Scoping Review.

Objectives: There has been increased interest in using telepractice in clinical services during COVID-19. Using telepractice is little known in speech and language therapy. However, the parents and speech therapists were satisfied with this method. Therefore, this scoping review aims to compare tele speech therapy and face-to-face speech therapy during the COVID-19 pandemic and determine the efficacy of available telepractices in speech therapy. Materials & Methods: This scoping review was according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR) guideline. The authors systematically searched Web of Science, PubMed, and Scopus databases with specific eligibility criteria. The eligibility criteria were studies published from 1 January 2020 to 10 May 2023 from a peer-reviewed journal and written in English. In addition, the articles were about speech therapy in children during COVID-19. Results: Fifteen articles were included in this scoping review. Results showed that approximately all speech therapists used tele practice during the pandemic. Parents and students are satisfied with this method but have problems with it. On the other hand, some parents and SLPs preferred tele practice accompanied by face-to-face intervention. Furthermore, few studies determined the efficacy of tele practice with clear structural methods in specific populations. Conclusion: Although tele speech therapy is acceptable for providing speech and language therapy services to children with swallowing and communication disorder, speech-language therapists should increase their information and technology to achieve successful results. Moreover, parents must play an essential role in telepractice services to facilitate effective communication between clinicians and families.

Validity and reliability of the Persian version of greenspan social-emotional growth chart.

Background: The estimated prevalence of mental health disorders in children and adolescents is between 10% and 20%. Furthermore, a quarter of very premature infants exhibit socioemotional delays in infancy and childhood. The objective of this study was to determine the validity and reliability of Greenspan social-emotional growth chart (GSEGC) in Persian children aged 1-42 months. Materials and Methods: After translation procedures, the face validity, content validity, construct validity, test-retest reliability, and internal consistency of the GSEGC questionnaire were evaluated. The quality of translating items was obtained using the suggestions of the research group. The face validity of the GSEGC was performed by interviewing with 10 mothers in the target group. To evaluate content validity quantitatively, content validity ratio (CVR) and content validity index (CVI) were used after reviewing the face and content validity and pilot study, 264 parents of children aged 1-42 months completed the GSEGC questionnaire to assess the construct validity and internal consistency. In order to determine the test-retest reliability, after 2 weeks, 18 parents completed the questionnaire again. Results: Eleven questions were changed according to the interviews (questions 1-6, 9-11, and 15-16). The lowest CVR was related to items 30 and 20 (0.636), and other items had an acceptable CVR. The lowest CVI value was related to item 1 of clarity and simplicity (0.818), and other items had an acceptable CVI. Intra-class correlation coefficient was 0.988 for all items of questionnaire. Furthermore, Cronbach's alpha coefficient was 0.952 for all items. In factor analysis, two factors were extracted from the items in questionnaire. Conclusion: The Persian version of GSEGC questionnaire has acceptable face, content and, constructs validity, test-retest reliability and high internal consistency in the target population. Therefore, the Persian version of the GSEGC can be used as a tool to assess 1-42 months sensory processing and socio-emotional development.

A Comparison Study of the Tehran Norms to the Reference Norms on Children Performance of the Bayley III.

Objectives: The Bayley Scales of Infant and Toddler Development (3rd ed.; Bayley III) are widely used to assess cognitive, language, and motor development of children aged 1-42 months. It is unclear whether or not the reference norms of the Bayley III are acceptable for use in other populations or lead to over- or underestimating the developmental status of target children. This study aimed to compare the Tehran norms to the reference norms. Materials & Methods: We used Bayley III norms to assess cognitive, language, and motor development of 1,674 healthy children from health care centers in Tehran. Differences between the scaled scores were calculated based on the Tehran and reference norms. A one-sample multivariate analysis of variance (MANOVA) was used to control the mean difference scores over all subtests. When MANOVA showed significant differences between the scaled scores based on the Tehran and reference norms, we used univariate analysis to see which subtest and age group led to these significant differences. Finally, the proportions of children with low scores (scaled scores <7 or -1 SD and <4 or -2 SD) based on 2 norms were compared using the McNemar test to determine the over- or underestimation of developmental delay. Results: The scaled scores based on the Tehran norms varied across values based on the reference norms in all subtests. The mean differences were significant in all 5 subtests (p < .05) with large effect sizes for receptive and expressive communication, fine and gross motor subtests of .20, .23, .14, and .25, respectively, as well as with a small effect size for the cognition subtest of .02. Large effect sizes for all age groups were found for cognition, expressive communication, and fine motor subtests. More children scored below 1 and 2 SD using the Tehran norms. Using the reference norms resulted in underestimation of developmental delay regarding cognitive, receptive and expressive communication, and fine and gross motor skills. Conclusion: Population-specific norms should be used to identify children with low scores for referral and intervention. The Tehran norms differed from the reference norms for all subtests, and these differences were clinically significant.

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

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 (b = -0.111), experience of father's care (b = -1.112), conflict with mother (b = 0.309), conflict with father (b = 0.135), and exposure to domestic violence (b = 0.217), as well as age (b = 0.93) and gender (b = 0.139), had direct effect on adolescent mental health (all P < 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.

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.

Effects of Developmental Care on Neurodevelopment of Preterm Infants.

OBJECTIVES: The aim of this study protocol is to systematically review the literature to examine the effects of developmental care on preterm infants' neurodevelopment in the neonatal intensive care unit (NICU). MATERIALS & METHODS: Studies will be retrieved through searching the following databases: Web of Science, PubMed, EMBASE (Ovid), Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL (EBSCO), and Scopus. Randomized controlled trials will be included with randomization at either individual or cluster level. The primary outcome will be to evaluate the effect of developmental care on the mental and motor development of NICU neonates. The secondary outcome will be neonatal weight gain and length of stay during NICU hospitalization. The assessment tool for the development should be the Bayley Scales of Infant and Toddler Development, in any of the first, second and third editions. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) will be employed to identify relevant articles and report the screening process. The agreement between two experts in developmental neonatology will be reached in selecting all studies. Afterward, data will be extracted and compared by two reviewers. Any discrepancies in the extracted data will be discussed to reach a consensus. The extracted data will be imported to Review Manager 5.3 by one reviewer. Finally, the risk of bias for all selected studies will be independently evaluated by two reviewers using the Cochrane Collaboration's tool. A meta-analysis will be performed to assess the possible quantitative impact of developmental interventions on the desired primary and secondary objectives. A random effect will be used if the I-square statistics is equal or more than 75%; otherwise, a fixed effect will be applied. Publication bias will be assessed using Egger's test and illustration with the funnel plot. The Standardized Mean Difference (SMD) with 95% confidence interval will be estimated through Metan command in STATA 14. The method provided in the Cochrane handbook will be used in this statistical analysis. The significance level will be 0.05.

Do NICU developmental care improve cognitive and motor outcomes for preterm infants? A systematic review and meta-analysis.

BACKGROUND: The aim of this study was to review the effects of developmental care in neonatal intensive care unit (NICU) setting on mental and motor development of preterm infants. METHOD: We searched PubMed, EMBASE, CINAHL, Scopus, Web of Science and Cochrane library until October 8th 2017, and included randomized controlled trials that assessed effects of developmental care in NICU on mental and motor development of preterm infants at 12 and 24 months of age, using the Bayley scale of infant development in this systematic review. In addition, data were pooled by random effects model and Standardized Mean Difference (SMD) with 95% confidence intervals (CI), calculated for meta-analysis. RESULTS: Twenty one studies were eligible to be included in this systematic review; however, only thirteen studies had data suitable for meta-analysis. According to statistical analysis, developmental care in NICU improved mental developmental index (MDI) (standardized mean difference [SMD] 0.55, 95% confidence interval [CI] 0.23-0.87; p < 0.05), and psychomotor developmental index (PDI) (SMD 0.33, [CI] 95% CI 0.08-0.57; p < 0.05) of BSID at 12 months of age and PDI at 24 months of age (SMD 0.15, 95% CI -0.02-0.32; p < 0.1) of preterm infants. However, the benefit was not detected at 24 months of age on MDI (SMD 0.15, 95% CI -0.05-0.35; p = 0.15). CONCLUSION: Current evidence suggests that developmental care in only NICU setting could have significant effect on mental and motor development of preterm infants, especially at 12 months of age. However, because of clinical heterogeneity, more studies are needed to evaluate the effects of developmental NICU care in the development of preterm infants.

The Psychometric Properties of the Persian Version of Childhood Experience of Care and Abuse Questionnaire (CECA).

BACKGROUND: The present study aimed to determine the psychometric properties of the Persian version of the Childhood Experience of Care and Abuse Questionnaire (CECA.Q), a tool based on a retrospective interview with the child. MATERIALS AND METHODS: To this aim, 251 adolescents from four regions of Tehran megacity completed the questionnaire. The reliability of the questionnaire was examined, along with the face and content validity. In addition, the construct validity was evaluated by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). RESULTS: EFA and CFA supported a 4-factor solution including mother's role scale items, father's role scale items, maternal behavior scale items, and paternal behavior scale items. The total variance extracted in EFA ranged from 33.9 to 60.7. The internal consistency for mother's role, father's role, maternal behavior, and paternal behavior was 0.61, 0.65, 0.86, and 0.9 respectively. Thus, the questionnaire had a suitable fit, as well as reasonable reliability and validity. CONCLUSION: The Persian version of the CECA.Q had adequate reliability and validity as a self-report measurement for childhood experience of care and abuse.

Prevalence and determinant factors of anemia in children aged 6-12 months after starting an iron supplement in the east of Iran.

OBJECTIVE: Anemia in infants is a common problem, with regular iron supplementation the suggested policy for prevention and control of anemia. The aim of this study was to determine the prevalence and the determining factors of anemia as well as the benefits of regular iron supplementation in 6- to 12-month-old children. DESIGN/SETTING/SUBJECTS: In this cross-sectional study, 897 children aged from 6 to 12 months cared for at the Tabas Health Centers, affiliated with Birjand University of Medical Sciences, South Khorasan, Iran, were enrolled in the study. Demographic and anthropometric data as well as the level of hemoglobin were collected through interviews and laboratory tests, respectively. Data analysis was performed using SPSS-22 and stata-13. Chi2, polychromic PCA, and logistic regression were used. The statistical significance level was 0.05. RESULT: The prevalence of anemia, according to the WHO criterion for hemoglobin, was 36.8% (95% CI, 33.6-40.0). Its prevalence showed a decreasing trend as age and duration of iron supplement increased. Each 1-month increase in infant age was associated with a decreased risk of anemia [OR=0.88 (95% CI, 0.80-0.98)]. Anemia was not significantly different between genders. Individuals in the highest category for parity (≥3) were at a 2.3-fold greater risk of anemia compared with the lowest category [OR=2.35 (95% CI, 1.43-3.84)]. In contrast, individuals in the highest category for maternal age (>35 years) had a 62% lower risk of anemia compared with the reference category (<25 years) [OR=0.38 (95% CI, 0.20-0.72)]. CONCLUSION: Implementation of an iron supplementation plan in Iran has decreased anemia among 6- to 12-month-old children.

The effects of premature infant oral motor intervention (PIOMI) on oral feeding of preterm infants: A randomized clinical trial.

OBJECTIVE: Given the increase in the birth and survival rate of the premature infants, a need for supportive health care services becomes more evident. The goal of the present study was to examine the effectiveness of the Premature Infant Oral Motor Intervention (PIOMI) in the feeding progression and early intervention. This study was a double-blind randomized clinical trial. METHODS: This clinical trial included premature infants in the neonatal intensive care units (NICUs) of two hospitals in Tehran, who were randomly assigned into intervention and control group, each containing 15 infants. The PIOMI was administered to the intervention group in the course of 10 days. The infants in the control group received routine nursing services. Repeated measures ANOVA (RMA) were analyzed. The postmenstrual age and weight of the participants were examined at the time points of accomplishing one, four, and eight oral feedings a day and at the time of hospital discharge. RESULTS: The intervention group reached the first oral feeding (with a mean of 7.2 days) and eight oral feeding (with a mean of 13.47 days) earlier than the control group. The length of hospital stay in intervention group was significantly shorter (P = 0.03). RMA wasn't statistically significant between groups for weight (F: 0.76, P: 0.39, ŋ: 0.03); but within-subjects test showed that change of the weight over time and for interaction of time and group was significant (F: 74.437, P < 0.001, ŋ: 0.727). The effect size of infants' age in the measurement times was 91%. CONCLUSION: the results revealed that PIOMI is a fruitful method for premature infants. We suggest that PIOMI can be integrated in feeding rehabilitation programs of the premature infants born with gestational age of as young as 26-29 weeks, and applied at 29 weeks postmenstrual age (PMA). THE CLINICAL TRIAL REGISTRATION NUMBER: IRCT20180410039260N1.

The Effect of Non-Nutritive Sucking and Maternal Milk Odor on the Independent Oral Feeding in Preterm Infants.

OBJECTIVES: Given the positive effects of stimulation with breast milk odor and non-nutritive sucking (NNS) on preterm feeding skills, we examined the effect of NNS and milk odor, on the time of achieving independent oral feeding in preterm infants. MATERIALS & METHODS: This study was conducted at two Neonatal Intensive Care Units of Tehran, Iran in 2016. Overall, 32 neonates with gestational ages of 28-32 wk were enrolled in two groups; NNS with and without olfactory stimuli (breast milk odor). The simulations were performed in both groups during the first five minutes of gavage, three times per day, and over ten consecutive days. Weight gain, time of achieving oral feeding and chronological age at discharge were as measures of the effectiveness of the interventions. The results of the interventions were analyzed and compared using SPSS.18. RESULTS: NNS with breast milk odor resulted to a lower post-menstrual age at the first oral feeding, independent oral feeding and discharge from the hospital, but had no effects on their daily weight gain and weight at the time of discharge. CONCLUSION: These results show the effectiveness of combining milk odor and NNS as two important stimuli in achieving oral feeding and earlier discharge from the hospital.

Are the Norms of Bayley Screening Test Appropriate for Persian Language Children?

OBJECTIVE: We aimed to assess the distribution of the Bayley screening test by age, and compare developmental risk category distributions between Persian language children and reference norms. MATERIALS & METHODS: A representative sample of 417 children, 1 to 42-months-old, by consecutive sampling from health -care centers were enrolled, during 2014 to 2015 in Tehran, Iran. The cognitive, language and motor development of children were evaluated using Bayley screening test. For determining cut-off point for the subtest scores, two cut-offs were determined for each age group, that classified children to the at risk, emerging, and competent categories. We estimated the agreement of the risk categories between the two samples using weighted kappa statistics. RESULTS: About 70%-80% of all tests operated to the participating children were classified as normal by both norms. Weighted kappa coefficients for the five subtests ranged from 0.56 to 0.89 suggesting moderate agreement between two classification norms. Expressive and receptive communication had the lowest kappa scores (0.56 and 0.59, respectively), and classification of gross motor revealed the highest level of agreement (0.89). CONCLUSION: Developmental disabilities are common disorders that impose important functional limitations on the affected children. Identifying infants at risk for developmental disorders by screening is a main step to minimize complications. Dependence on reference-based norms for the Bayley screening test in Persian language children results in misclassification of risk category.

A Psychometric Study of the Bayley Scales of Infant and Toddler Development in Persian Language Children.

OBJECTIVE: Bayley Scales of infant & toddler development is a well-known diagnostic developmental assessment tool for children aged 1-42 months. Our aim was investigating the validity & reliability of this scale in Persian speaking children. MATERIALS & METHODS: The method was descriptive-analytic. Translation- back translation and cultural adaptation was done. Content & face validity of translated scale was determined by experts' opinions. Overall, 403 children aged 1 to 42 months were recruited from health centers of Tehran, during years of 2013-2014 for developmental assessment in cognitive, communicative (receptive & expressive) and motor (fine & gross) domains. Reliability of scale was calculated through three methods; internal consistency using Cronbach's alpha coefficient, test-retest and interrater methods. Construct validity was calculated using factor analysis and comparison of the mean scores methods. RESULTS: Cultural and linguistic changes were made in items of all domains especially on communication subscale. Content and face validity of the test were approved by experts' opinions. Cronbach's alpha coefficient was above 0.74 in all domains. Pearson correlation coefficient in various domains, were ≥ 0.982 in test retest method, and ≥0.993 in inter-rater method. Construct validity of the test was approved by factor analysis. Moreover, the mean scores for the different age groups were compared and statistically significant differences were observed between mean scores of different age groups, that confirms validity of the test. CONCLUSION: The Bayley Scales of Infant and Toddler Development is a valid and reliable tool for child developmental assessment in Persian language children.

Effect of Orthotic Gait Training with Isocentric Reciprocating Gait Orthosis on Walking in Children with Myelomeningocele.

Background: Mechanical orthoses are used to assist in standing and walking after neurological injury in children with myelomeningocele (MMC). Objectives: To evaluate the influence of orthotic gait training with an isocentric reciprocating gait orthosis (IRGO) on the kinematics and temporal-spatial parameters of walking in children with MMC. Methods: Five children with MMC were fitted with an IRGO. They walked at their own comfortable cadence using the orthosis. The hip joint angle, spatial temporal parameters, and compensatory motions were measured and analyzed. Results: Significant increases in walking speed and step length were demonstrated following orthotic gait training during walking with the IRGO. The sagittal plane hip range of motion was also significantly increased; however, the vertical and horizontal compensatory motions were significantly decreased. Conclusion: This study evaluated the influence of gait training with an IRGO on the kinematics and temporal spatial parameters in MMC children. The findings showed that orthotic gait training improved hip joint range of motion, increased walking speed and step length, and decreased lateral and vertical compensatory motions during level-ground walking trials.

Scale Development and Psychometrics for Parents' Satisfaction with Developmental Care in Neonatal Intensive Care Unit.

OBJECTIVE: Developmental care comprises a wide range of medical and nursing interventions used in the neonatal intensive care unit (NICU) to mitigate and reduce stressors affecting preterm or ill neonates. Because patient satisfaction survey is a valuable quality improvement tool, we aimed to develop and test the psychometric properties of a tool for measuring parent satisfaction of developmental care in the NICU. MATERIALS &METHODS: In this psychometric methodological study, the item pool and initial questionnaire were designed based on a comprehensive literature review and exploring NICU parent satisfaction questionnaires. The validity of the designed questionnaire was determined using face, content (qualitative and quantitative), and construct validity. Exploratory factor analysis was performed using responses from 400 parents of infants hospitalized in the NICUs of 34 hospitals in 2015 in Tehran, Iran. The reliability of the questionnaire was identified using Cronbach's alpha and stability measures. RESULTS: The initial questionnaire was designed with 72 items in five domains. After testing the face validity, 3 items were omitted. The results of validity testing were acceptable. The exploratory factor analysis was performed on 69 items, and 5 factors (care and treatment with 20 items, information with 15 items, hospital facilities with 9 items, parental education with 7 items, and parental participation with 8 items) were extracted. The reliability was supported by high internal consistency (α = 0.92). CONCLUSION: This questionnaire could be valid and reliable tool for measuring parents' satisfaction.

Prevalence of Sleep Disorders Among Children 4 - 6 Years Old in Tehran Province, Iran.

BACKGROUND: Sleep patterns may change over a person's lifetime; however, the quantity and quality of sleep always depend on individual factors such as age, sex, and psychological and environmental factors. In children, sleep is as important as development. Quantitative sleep problems related to sleep onset and qualitative sleep disorders such as frequent awakenings may lead to insufficient sleep. OBJECTIVES: This study aimed to assess the prevalence of sleep disorders among children 4 - 6 years old attending the health centers of Shahid Beheshti University of Medical Sciences, Tehran, Iran, in 2013. PATIENTS AND METHODS: This was a cross-sectional study on 400 children selected using a multistage sampling method. Data were collected by interviews. The questionnaire included two sections: a demographic section with questions about the demographic characteristics of the children and parents and a children's sleep habit questionnaire (CSHQ). Data were analyzed by SPSS 16 and different statistical tests were used (P < 0.05). RESULTS: The mean age of the children was 64.27 ± 9.3 months. The prevalence of sleep disorders was 36.25%. Sleep disorders were significantly associated with age, height, body mass index, residence of children, father's occupation, mother's diseases, father's drug abuse, and parents' marital status (P < 0.05). CONCLUSIONS: Sleep disorders in children threaten growth and development, and are dangerous for their health. Sleep disorders should be considered in the differential diagnosis of children's learning and behavioral problems.

Development and psychometric testing of a scale for the assessment of the quality of developmental care in neonatal intensive care units in Iran.

INTRODUCTION: Developmental care provided to infants hospitalized at neonatal intensive care units (NICU) help weaken environmental stressors and reduce infant morbidity rates. Assessments are the first step to improving the quality of any type of care. Therefore, this study was conducted to design and assess the psychometric features of a scale designed for measuring quality of developmental care in the NICU in Iran. METHODS: This study was conducted from December 2014 through September 2015 in Tehran, Iran. The present mixed-methods sequential exploratory (quantitative-qualitative) study used the Delphi method to design an initial questionnaire through a review of the literature and by using the input of experts. The validity of the questionnaire was ensured by assessing then validity of its content (qualitative-quantitative), face (qualitative-quantitative), and construct (exploratory factor analysis with 500 NICU personnel from 34 hospitals in Tehran), and its reliability was ensured by assessing its internal consistency (using Cronbach's alpha) and by assessing its stability through the test-retest method. RESULTS: The qualitative stage of the study resulted in a 93-item questionnaire with eight domains. After performing the content and face analyses, a factor analysis was performed on 90 items of the questionnaire, yielding a 76-item questionnaire with five domains, including "sleep, pain and stress management," "routine care," "the family," "management," and "sensory care," which explained 62.5% of the variance. The reliability of the questionnaire was confirmed with a Cronbach's alpha of 0.9 and its stability was confirmed by an Intraclass Correlation Coefficient (ICC) of 0.93. CONCLUSION: The questionnaire developed for the assessment of developmental care in the NICU covered all of the dimensions of this type of care, and it is a valid and reliable tool for assessing and improving developmental care in the NICU.
