Adaptation and Preliminary Testing of the Developmental Coordination Disorder Questionnaire (DCDQ) for Children in India

Aims: While Developmental Coordination Disorder (DCD) has gained worldwide attention, in India it is relatively unknown. The revised DCD Questionnaire (DCDQ′07) is one of the most utilized screening tools for DCD. The aim of this study was to translate the DCDQ′07 into the Hindi language (DCDQ-Hindi) and test its basic psychometric properties. Methods: The DCDQ′07 was translated following guidelines for cross cultural adaptation of instruments. Parents of 1100 children (5–15 years) completed the DCDQ-Hindi, of which 955 were considered for data analysis and 60 were retested randomly after 3 weeks for test–retest reliability. Results: The DCDQ-Hindi showed high internal consistency (α = .86) and moderate test–retest reliability (.73). Confirmatory factor analysis showed equivalence to the DCDQ′07. The% probable DCD using DCDQ′07 cutoff scores (≤57) ranged from 22% to 68%. Using more stringent cutoffs (≤36) it ranged from 5% to 9%. Significant difference was seen for gender (p < .05) in subset 1(gross-motor skills) total scores. Conclusions: The DCDQ-Hindi reveals promise for initial identification of Hindi speaking Indian children with DCD. Based on more stringent cut-off scores, the “probable prevalence” of children with risk of DCD in India appears to be around 6–7%. Research with larger sample and comparison with the MABC-2 or equivalent is needed.     

Cross-cultural adaptation,reliability and predictive validity of the Italian version of Developmental Coordination Disorder Questionnaire (DCDQ)

BackgroundDevelopmental coordination disorder (DCD) is a motor disorder of unclear etiology that severely interferes with a child's ability to perform daily motor tasks. As a useful alternative to a time-consuming motor test and specialist evaluation, parents or teachers can complete motor questionnaires. A tool used worldwide to screen motor performance in 4- to 14-year-old children is the Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07).AimsTo describe how we translated the Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07) and adapted it to the Italian population and to test its preliminary psychometric properties in Italian children.MethodsParents of a clinical group of 26 children (5–11 years old) with a diagnosis of DCD and 52 matched controls completed the DCDQ translated into Italian and adapted for cross-cultural purposes according to current guidelines. Twenty-four parents of typically developing children randomly selected completed the questionnaire twice to examine test–retest reliability.ResultsThe internal consistency value (Cronbach alpha) for the Italian DCDQ was 0.94. The Italian DCDQ achieved moderate-to-high test–retest reliability (ICC) for 14/15 items and a good diagnostic performance for identifying children with DCD (sensitivity 88% and specificity 96%).ConclusionsThe Italian DCDQ is a valid screening tool for assessing motor performance in 5- to 11-year-old children that merits research in a larger sample.     

Psychometric Properties of the Canadian Little Developmental Coordination Disorder Questionnaire for Preschool Children

ABSTRACT

Aims: Test the psychometric properties and cut-off scores for the Canadian Little Developmental Coordination Disorder Questionnaire (Little DCDQ), which screens for coordination difficulties in children aged 3 to 4 years. Methods: Parents of children with typical development (n = 108) and children at risk for motor problems (n = 245) completed the questionnaire. A subgroup (n = 119) of children was tested with the Movement Assessment Battery for Children-2 (MABC-2) and the Beery–Buktenica Developmental Test of visual-motor integration (VMI) to determine motor impairment (MI). Results: Test-retest reliability (r = 0.956, p < .001) and internal consistency (Cronbach's alpha = 0.94) were high. Construct validity was supported by a factor analysis and significant difference in scores of children who were typically developing and were at risk. Concurrent validity was evaluated for the children who received standardized motor testing, with significant difference between children with and without MI. Discriminant function analysis showed that all 15 items were able to distinguish the two groups. The questionnaire correlated well with the MABC-2 and VMI. Validity as a screening tool was assessed using logistic regression modeling (X²(5) = 25.87, p < .001) and receiver operating curves, establishing optimal cut-off values with adequate sensitivity. Conclusions: The Little DCDQ is a reliable, valid instrument for early identification of children with motor difficulties.     

European-French Cross-Cultural Adaptation of the Developmental Coordination Disorder Questionnaire and Pretest in French-Speaking Switzerland

ABSTRACT

The Developmental Coordination Disorder Questionnaire (DCDQ’07) is a Canadian-English instrument recommended for screening children aged 5 to 15 years who are at risk for developmental coordination disorder. While a Canadian-French version of the DCDQ’07 presently exists, a European-French version does not. Aims. To produce a cross-cultural adaptation of the DCDQ’07 for use in areas of Europe where French is spoken and to test its cultural relevance in French-speaking Switzerland. Methods. Cross-cultural adaptation was done using established guidelines. Cultural relevance was analyzed with cognitive interviews of thirteen parents of children aged 5.0 to 14.6 years (mean age: 8.5 years, SD = 3.4), using think-aloud and probing techniques. Results. Cultural and linguistic differences were noted between the European-French, the Canadian-French, and the original versions of the DCDQ’07. Despite correct translation and expert committee review, cognitive interviews revealed that certain items of the European-French version were unclear or misinterpreted and further modifications were needed. Conclusions. After rewording items as a result of the outcomes of the cognitive interview, the European-French version of the DCDQ’07 is culturally appropriate for use in French-speaking Switzerland. Further studies are necessary to determine its psychometric properties.     

Motor Planning and Gait Coordination Assessments for Children with Developmental Coordination Disorder

Aims: The purposes were to examine construct validity of the Motor Planning Maze Assessment (Maze) and three items from the Functional Gait Assessment (FGA) that were modified for children (pediatric modified FGA, pmFGA), by comparing performance of children with DCD and age matched peers with typical development (TD); the construct validity of total scores of the Dynamic Gait Index (DGI) and the FGA. Methods: Twenty pairs of children with DCD and TD, age from 5 to 12 years, participated in this study. Children in both groups were tested on the Maze, pmFGA, DGI, and FGA. Paired t-tests and agreement tables were used to compare the motor performances between two groups. Results: The DCD group showed higher summary scores in the Maze (p < 0.001) and demonstrated significantly fewer steps (p ≤ 0.001) while doing the pmFGA items than the TD group. However, the FGA quality scores demonstrated minimal differences between the two groups on all three items. Children with DCD showed significantly lower DGI and FGA total scores (p < 0.001) than the TD group. Conclusion: The Maze, DGI, and FGA tests are easily applied in clinical settings and can differentiate motor planning and gait coordination between children with DCD and with TD.     

Validation of the Revised Child Version of the Assessment of Computer Task Performance

Objective. The purpose of this study was to examine test-retest reliability, internal consistency, and construct validity of the revised child version of the Assessment of Computer Task Performance. The subjects were 155 children of 5 to 11 years of age who did not have any visual or motor impairment. Children 5 through 9 years of age were administered the revised test, which included some additional tasks. Children 10 and 11 years of age were administered selected tasks from the adult version. A subgroup of 52 children were administered the test for the second time to examine test-retest reliability. Intra-class correlations for the mean time to complete two trails indicated moderate to good test-retest reliability (0.66–0.91). The alpha coefficient for tasks administered to children 5 through 9 years of age (0.85) supports internal consistency. Removal of one task increased the alpha coefficient to 0.79 for tasks administered to children 10 and 11 years of age. Three factors explained 84% of the total variance in scores of children 5–9 years of age and 75% of the variance in scores of children 10 and 11 years of age. The mean time to complete keyboard tasks decreased with age and the mean time to mouse tasks decreased between 5 and 9 years. Conclusion. The results provide evidence of test-retest reliability, internal consistency, and construct validity of the revised Assessment of Computer task Performance.     

家庭环境与学龄前儿童发育性协调障碍的相关性

目的探讨家庭环境对学龄前儿童发育性协调障碍(DCD)的影响。方法按分层随机整群方法抽取4~6岁儿童1 727例,应用"儿童运动协调能力成套评估工具"对其进行DCD筛查;采用"城市学龄前儿童运动发育家庭环境量表"及自行设计的问卷评估儿童家庭环境状况。结果 117例儿童确诊为DCD。DCD组和正常对照组儿童在母亲文化程度、家庭结构的比较中差异有统计学意义。家庭环境因素中"让孩子管理自己的日常物品"和"包办孩子一切事务"两项得分在DCD组和正常对照组儿童之间差异有统计学意义。在控制儿童性别、年龄情况下,多因素logistic回归分析显示,"母亲文化程度""家庭结构""让孩子管理自己的日常物品"及"包办孩子一切事物"是影响儿童DCD发生的主要因素(均P0.05)。结论家庭环境对学龄前儿童DCD的发生存在影响,家长在养育孩子的过程中,不要包办孩子一切事务,应为儿童提供更多的管理自己日常生活的机会,以促进其早期运动协调能力的发展,预防DCD的发生。     

ITP-QoL Questionnaire for Children with Immune Thrombocytopenia: Italian Version validation's

Background: The ITP-QoL is a disease-specific questionnaire for the assessment of health-related quality of life (HRQoL) in children with immune thrombocytopenia (ITP) and their parents. The aim of this study was to test the psychometric characteristics of the ITP-QoL in the Italian pediatric population in terms of validity and reliability. Procedure: Children aged 8–16 years with acute or chronic ITP and their parents were recruited in Italy. Participants completed the ITP-QoL together with other patient-reported outcomes (PROs). Reliability was calculated using Cronbach's alpha. Convergent validity was determined by means of the Pearson correlation coefficients. Results: A total of 91 ITP patients, mean age of 12.11 ± 2.47 years, and their parents participated; 61.5% of the patients were female. Two patients had acute ITP and 30.2% had a moderate to severe status of ITP. Cutaneous symptoms were more frequent than mucosal symptoms. Due to item and scale analyses 20 items were deleted from the original ITP-QoL. Internal consistency of the ITP-QoL was found to be good with Cronbach's alpha exceeding α = 0.70 for all but one subscale. Concerning convergent validity “moderate” to “high” negative correlations were found between ITP-QoL and KINDL subscales. The ITP-QoL was able to discriminate between clinical subgroups such as number of days lost at school due to ITP and hospitalization. Conclusions: Our study was able to demonstrate that the Italian version of ITP-QoL (for children aged 8–16 years) is a valid and reliable instrument for the assessment of HRQoL in children with ITP.     

Calidad de vida relacionada con la salud informada por los padres en preescolares españoles: propiedades psicométricas del Kiddy-KINDL-R

IntroductionAlthough several tools have been developed to assess general HRQoL in children, parental reports are required to supplement this information, especially in very young children. The parents version of the Kiddy-KINDL-R was developed to assess HRQoL in children aged 3 to 7 years through the reports of their parents or legal guardians.ObjectiveThe aim of this study was to validate the parents version of the Kiddy-KINDL-R questionnaire and assess its psychometric properties in a sample of Spanish preschool-aged children.MethodCross-sectional study in 283 parents or legal guardians of children aged 3 to 6 years that completed the Kiddy-KINDL-R questionnaire and an additional scale to assess anxiety problems. We performed confirmatory factor analysis to assess whether the original Kiddy-KINDL-R version fit the Spanish data; we assessed internal consistency by means of the ordinal alpha and the discriminant validity by means of the Preschool Anxiety Scale.ResultsAlthough the original six-factor model showed a good fit, we propose a model consisting of 22 items and the same 6 factors for the Spanish version. The reliability was excellent, and the internal consistency values were adequate. Our results showed significant negative correlations between the Kiddy-KINDL-R and the external anxiety measure, which was evidence of discriminant validity.ConclusionWe demonstrated that the Spanish version of the Kiddy-KINDL-R had good psychometric properties and that this questionnaire is an adequate assessment tool that could be useful in clinical practice.     

The Paediatric Asthma Caregiver's Quality of Life Questionnaire in Swedish parents

With the Paediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ), parents grade impaired activities (5 items) and emotional concern (8 items) from 1 to 7 regarding how much their own quality of life (QoL) has been affected by the disease of their child during the last week. The questionnaire was translated into Swedish. To test the feasibility and validity of the Swedish version, 71 asthmatic children and their families were approached. Sixty-one families (86%) participated. The mean age of the children was 8.7 y. Parental grading of symptoms (Spearman's rho = 0.637, p < 0.001), the asthma-specific QoL of the child (rho = 0.359, p = 0.002) and gradings of asthma from medical records (mild asthma median score 6.69, moderate 6.27 and severe 5.12, p = 0.001) were all related to overall PACQLQ scores. The sex of the child, the presence of other diseases related to allergy, peak flow rate (PEFR) and socio-economic level did not affect the scores. Lower scores in the emotional domain were seen in parents of children on steroids (p = 0.049). The distribution of scores was heavily skewed towards the positive end of the scale, leading to limited power to discriminate among parents of children with mild asthma. The instrument had good internal consistency and was well accepted by the parents.     

Pediatric Functional Constipation Questionnaire-Parent Report (PedFCQuest-PR): development and validation

ObjectiveDeveloping and validating a disease-specific instrument in the Brazilian Portuguese language to assess the Health-Related Quality of Life of children with functional constipation, applied to parents/caregivers.MethodsThe process of developing the questionnaire was carried out in the following steps: items generation concerning functional constipation; elaboration of the preliminary questionnaire; assessment by health professionals; identifying problems or inconsistencies by the researchers; improvement of the questions; obtaining a final questionnaire named Pediatric Functional Constipation Questionnaire-Parent Form (PedFCQuest-PR) with 26 questions divided into four domains. Responses options use a Likert scale based on the events of the last four weeks. The process of validation was an observational, cross-sectional study in a sample of 87 parents/caregivers of children from 5 to 15 years of age diagnosed with Functional constipation according to the Rome IV Criteria. The questionnaire was applied simultaneously to the Pediatric Quality of Life Inventory 4.0 (PedsQL TM 4.0) as a control.ResultsThe questionnaire validation included 87 parents/caregivers. The children's median age was 8.2 years, with a long time of constipation symptoms associated with fecal incontinence in approximately two-thirds. Internal consistency reliability for the Total Scale Score of PedFCQuest-PR by Coefficient Alpha of Cronbach score was 0.86. Convergent and divergent validity of PedFCQuest-PR was demonstrated by correlating the domains of both questionnaires.ConclusionThis study provides evidence that PedFCQuest-PR is a reliable instrument. The results showed a high degree of internal consistency and validity of the instrument for future applications.

Identifying Developmental Coordination Disorder

Summary

In the absence of a gold standard to identify the presence of developmental coordination disorder in children, it is useful to examine the consistency of different tests used in physical and occupational therapy. This study examined three measures of motor skills to determine whether they consistently identified the same children. In total, 379 children participated in this study. The final matched samples consisted of 202 children ranging in age from 8 to 17 years: 101 met criteria for DCD and 101 children did not show any evidence of DCD. The results indicated that the overall agreement between the Bruininks Oseretsky Test of Motor Proficiency (BOT), the Movement Assessment Battery for Children (M-ABC) and the Developmental Coordination Disorder Questionnaire (DCDQ) was less than 80%. The difference in structure and style of administration between the BOT and the M-ABC appears to contribute to their tendency to identify different children. This studyemphasizes the need for therapists to use clinical reasoning to examine multiple sources of information about a child's abilities.     

The Parent Supervision Attributes Profile Questionnaire: a measure of supervision relevant to children''s risk of unintentional injury

OBJECTIVE: To further establish the psychometric properties of the Parent Supervision Attributes Profile Questionnaire (PSAPQ), a questionnaire measure of parent supervision that is relevant to understanding risk of unintentional injury among children 2 through 5 years of age. METHODS: To assess test-retest reliability, parents completed the PSAPQ twice, with a one month interval. Internal consistency estimates for the PSAPQ were also computed. Confirmatory factor analyses were applied to the data to assess the four factor structure of the instrument by assessing the convergent and divergent validity of the subscales and their respective items. RESULTS: Test-retest reliability and internal consistency scores were good, exceeding 0.70 for all subscales. Factor analyses confirmed the hypothesized model--namely that the 29 item questionnaire comprised four unique factors: protectiveness, supervision beliefs, risk tolerance, and fate influences on child safety. CONCLUSIONS: Previous tests comparing the PSAPQ with indices of actual supervision and children's injury history scores revealed good criterion validity. The present assessment of the PSAPQ revealed good reliability (test-retest reliability, internal consistency) and established the convergent and divergent validity of the four factors. Thus, the PSAPQ has proven to have strong psychometric properties, making it a unique and useful measure for researchers interested in studying links between supervision and young children's risks of unintentional injury.     

Measuring Outcomes of Family-Centered Intervention: Development of the Life Participation for Parents (LPP)

Raising a child with disabilities impacts the ability of parents to participate in life situations. This paper describes the development of a new instrument, Life Participation for Parents, to measure outcomes of pediatric therapy on parental participation. Items were reviewed by six occupational therapists with experience in pediatrics and instrument development. The number of items was reduced to 23. The resultant instrument was completed by 29 parents of children with disabilities. Their scores were reviewed by the nine occupational therapists working with the children. Parent and therapist respondents were interviewed regarding item content. Instrument responses were evaluated for internal consistency. The respondents confirmed the face and content validity of the construct, variability in responses, and readability of the items. Good internal consistency for items was demonstrated (Cronbach's alpha. 85). The preliminary results indicate that the Life Participation for Parents is a promising tool for evaluating parental issues and measuring parent outcomes in family-centered practice.     

Identifying developmental coordination disorder: consistency between tests

In the absence of a gold standard to identify the presence of developmental coordination disorder in children, it is useful to examine the consistency of different tests used in physical and occupational therapy. This study examined three measures of motor skills to determine whether they consistently identified the same children. In total, 379 children participated in this study. The final matched samples consisted of 202 children ranging in age from 8 to 17 years: 101 met criteria for DCD and 101 children did not show any evidence of DCD. The results indicated that the overall agreement between the Bruininks Oseretsky Test of Motor Proficiency (BOT), the Movement Assessment Battery for Children (M-ABC) and the Developmental Coordination Disorder Questionnaire (DCDQ) was less than 80%. The difference in structure and style of administration between the BOT and the M-ABC appears to contribute to their tendency to identify different children. This study emphasizes the need for therapists to use clinical reasoning to examine multiple sources of information about a child's abilities.     

Parent experiences of paediatric care (PEPC) questionnaire: reliability and validity following a national survey

AIM: To describe the development and evaluation of a parent completed questionnaire to measure parent experiences of inpatient paediatric care, the parent experiences of paediatric care (PEPC). METHODS: Literature review, parent interviews, pre-testing and a national survey of 6144 parents of children who were inpatients at one of the 20 paediatric departments within Norway in 2005. RESULTS: Three thousand three hundred and eight (53.8%) parents responded to the questionnaire. Low levels of missing data suggest that the PEPC is acceptable. The questionnaire includes six scales as supported by the results of factor analysis: nursing services (seven items), doctor services (five items), organisation (four items), information--examinations and tests (two items), information--discharge (three items) and hospital facilities (four items). Cronbach's alpha and test-retest correlations ranged from 0.7 to 0.9. Comparisons of scale scores with several variables including overall satisfaction with care and pain control, supported validity. CONCLUSION: The PEPC questionnaire includes important aspects of hospital care from the perspective of the parent. It has good evidence for internal consistency, test-retest reliability and validity and is recommended in surveys of parent experiences of paediatric inpatient care.     

Knowledge and food practices questionnaire: construction and validation

ObjectivesTo develop and validate an instrument about nutritional knowledge and feeding practices to be used in children aged 7–11 years, based on the latest Brazilian Food Guide.MethodsReview on the subject; instrument creation; content validity with two groups of judges: first, nutritionists and, after adjustments, a multidisciplinary group (content validity index [CVI]); FACE validity; reproducibility analysis (intraclass correlation coefficient [ICC], level of agreement, and kappa [k]); internal consistency analysis (Cronbach's alpha[α]) and construct validity (Kaiser–Meyer–Olkin and exploratory factorial analysis). The sample was calculated, considering at least ten subjects for each question of the questionnaire.ResultsThere was a final sample of 453 children (53.6% girls), with a mean age of 9.45 years (SD = 1.44). The content validity showed a CVI ≥ 0.80 for relevance in 62.3% of the items for nutritionists’ group and 100% of the items for the multidisciplinary group, clarity (49.4%, 91.8%), and pertinence (58.8%, 98.4%), respectively. The test-retest showed a level of agreement of 84.3% and k = 0.740 for the Knowledge dimension and ICC = 0.754 for the Food Practices dimension. The internal consistency showed α = 0.589 for the Knowledge dimension and α = 0.618 for the Food Practices dimension. For the construct validity, Kaiser–Meyer–Olkin was 0.724 and exploratory factorial analysis showed a variance of 47.01 with varimax rotation and defined five factors for the Practices Dimension.ConclusionThe Food Knowledge and Practices Questionnaire (Questionário de Conhecimento e Práticas Alimentares [QCPA]) instrument showed validity and reliability to assess nutritional knowledge and food practices in children aged 7–11 years.     

Knowledge to Practice in Developmental Coordination Disorder: Impact of an Evidence-Based Online Module on Physical Therapists’ Self-Reported Knowledge,Skills, and Practice

ABSTRACT

Aims: To evaluate the impact of an evidence-based online module on Developmental Coordination Disorder (DCD) on self-reported physical therapist (PT) knowledge, skills, and practice. Methods: Fifty PTs completed a questionnaire before and after the completion of the online module, with 41 PTs completing the same questionnaire 2 months later. The questionnaires included items rated using a 7-point Likert Scale and short open-ended questions. Results: There was a significant effect of Time for 17 out of 18 items on self-reported knowledge, and all 19 items for self-reported skills. Post-hoc analyses indicated that mean scores at Time 2 and Time 3 were higher than the mean scores at Time 1. Forty-six (92%) participants reported an increase in their confidence to provide evidence-based services. Forty-three (86%) participants indicated their intentions to modify their evaluative practices (e.g., involving children in goal setting) and their management of DCD (e.g., using the best practice principles, providing resources to families). At the 2-month follow-up, 19 (46%) participants had returned to the module to review information (e.g., video, resources) or to download handouts. Conclusions: The online DCD module appears to be an effective knowledge translation strategy to increase PTs’ self-reported knowledge and skills, and to support evidence-informed practice.     

Aquatic Physical Therapy for Children with Developmental Coordination Disorder: A Pilot Randomized Controlled Trial

ABSTRACT

Aquatic therapy is an intervention for children with Developmental Coordination Disorder (DCD) that has not been investigated formally. This was a pilot randomized controlled trial to investigate the feasibility and preliminary effectiveness of an aquatic therapy program to improve motor skills of children with DCD. Thirteen children (mean age 7 years 1 month; 10 males) with DCD were randomly allocated to receive either six sessions of aquatic therapy (once weekly session of 30 min for 6–8 weeks) or to a wait-list (control group). The intervention and measures were demonstrated to be feasible, but barriers, such as limited appointment times and accessibility, were encountered. Analysis of covariance indicated that at posttest, mean scores on the Movement Assessment Battery were higher for children who received aquatic therapy compared to those on the wait-list (p = .057). Similar trends were noted on the physical competence portion of the Pictorial Scale of Perceived Competence and Social Acceptance (p = .058). Participation levels, as measured by a parent questionnaire, showed improvement for both groups. Potential facilitators and barriers to implementation of an aquatic therapy for children with DCD are discussed.
