Co-occurrence of developmental delays among preschool children with attention-deficit–hyperactivity disorder

The aim of this study was to provide a comprehensive profile of the sensory, motor, language, and intellectual functioning of a non-referred community sample of 49 preschool children with attention-deficit-hyperactivity disorder (ADHD; 39 males, 10 females; mean age 4y 7mo [SD 7mo]; range 3y 10mo-6y) and 48 typically developing children (38 males, 10 females; mean age 4y 8mo [SD 6mo]; range 3y 11mo-6y) matched by age, sex, and maternal education who underwent a broad battery of neurodevelopmental tests. The results showed that the scores of the ADHD group were significantly lower than the comparison group on all measures. In addition, 23 (47%) of the children with ADHD had clinically significant co-occurring deficits in two or more areas. Logistic regression indicated that the only significant predictors of group classification were scores of verbal intelligence and motor and sensory functioning, accounting for 44.1% of the variance. These findings suggest that preschool children with ADHD have multiple developmental deficits over and above the core symptoms of ADHD and emphasize the importance of evaluating the sensorimotor functioning of preschool children with ADHD symptoms.

RELATION OF VISUAL PERCEPTION AND VISUAL-MOTOR INTEGRATION FOR CLUMSY CHILDREN '

The purpose of this study was to examine the relationship between visual perception and visual-motor integration in 30 normal children compared to 30 clumsy children. Difficulty in visual perception, as assessed by the Test of Visual-Perceptual Skills, accounts for about half the variance in the clumsy childrens performance in visual-motor integration, as assessed by the Developmental Test of Visual Motor Integration. In contrast, the correlation between scores on these tests for normal control children was low and not significant. These results suggest that visual perception and visual-motor integration may be separate functions in normally developing children. When considering clumsy children, however, these functions cannot be considered as two independent skills.

Development and psychometric properties of the Sensory Responsiveness Questionnaire (SRQ)

Purpose. Individuals with Sensory Modulation Disorder (SMD) are characterized by an inability to normally grade the degree, intensity and nature of their responses to sensory input and are limited in their ability to fully participate in daily life activities, and attain optimal quality of life. Most existing diagnostic tools are intended for paediatric populations. A questionnaire that assesses the intensity of the affective-emotive responsiveness of adults to stimuli in all sensory modalities and the frequency of such responses for diagnosing adults with disorders in sensory modulation is necessary. This article describes the development and assessment of the psychometric properties of a novel instrument, the Sensory Responsiveness Questionnaire (SRQ), for this purpose (see Appendix). Method. The SRQ evolved through three developmental phases (Pilot, Version-I, and the most recent Version-II). Each phase comprised several studies conducted to further refine the instrument and to examine its psychometric properties with adults with Sensory Modulation Disorder versus SMD-free individuals (n=39 for the pilot version, n=399 for Version-I, and n=48 for Version-II). Results. The scales of Version-II indicated high test-retest reliability, moderate criterion validity and strong significant construct validity. Conclusion. There is strong indication that the SRQ can be used to diagnose adults with SMD.

Differential diagnosis of sensory modulation disorder (SMD) and attention deficit hyperactivity disorder (ADHD): participation, sensation, and attention

Differential diagnosis between sensory modulation disorder (SMD) and attention deficit hyperactivity disorder (ADHD) is often challenging, since these disorders occur at a high rate of co-morbidity and share several clinical characteristics. Preliminary studies providing evidence that these are distinct disorders have focused solely on body functions, using sophisticated laboratory measurements. Moreover, no studies have compared participation profiles of these populations. This study is the first to compare the profiles of these populations regarding both “body functions” (attention and sensation) and “participation,” using measures applicable for clinical use. The study included 19 children with ADHD without SMD and 19 with SMD without ADHD (diagnosed by both pediatric neurologists and occupational therapists), aged 6–9, and matched by age and gender. All children underwent a broad battery of evaluations: the Evaluation of Sensory Processing, Fabric Prickliness Test (FPT) and Von Frey Test to evaluate sensory processing, and Test of Everyday Attention to evaluate attention components. The Participation in Childhood Occupations Questionnaire was used to evaluate participation. Results support significant group differences in all sensory components, including pain intensity to suprathreshold stimuli and pain “after sensation,” as well as in tactile, vestibular, taste, and olfactory processing. No differences were found in attention components and participation. This study has both theoretical and clinical importance, inter alia, providing further evidence of two distinct disorders as well as indications of specific clinical instruments that might enable clinicians to implement differential diagnoses. In addition, results accord with other previous statements, which indicate that the clinical diagnosis of children with disabilities may not be a major factor in determining their participation profile.

Perceptuomotor Functioning in Preschool Children with Symptoms of Attention Deficit Hyperactivity Disorder

Given limited research on perceptual-motor functioning of preschool children with symptoms of ADHD, the purpose of this study was to compare the fine motor, gross motor, visuomotor, and oral-motor functioning of 49 4- to 6-yr.-old children with symptoms of Attention Deficit Hyperactivity Disorder and 48 typically developing children. Analysis showed scores of the ADHD group were significantly lower than those of the control group on all perceptuomotor measures. In addition, scores on all measures yielded significant correlations with scores on the Hyperactive-Inattentive scale of the Preschool Behavior Questionnaire. Regression analyses indicated that the scores of gross motor and visuomotor functioning were significant predictors of group classification (with and without ADHD). These findings extend the well documented findings of perceptuomotor deficits among school-age children with ADHD into the preschool period and emphasize the importance of early assessment and treatment of these deficits in young children with symptoms of ADHD

The Participation in Childhood Occupations Questionnaire (PICO-Q): A Pilot Study

There is a need, among practitioners and researchers, for a feasible, user-friendly assessment tool that evaluates overall participation and guides intervention. This paper describes the process of construction and development of the Participation in Childhood Occupations Questionnaire (PICO-Q) and the establishment of its primary psychometric properties. The 22-item instrument measures the level, enjoyment, and frequency of performance for childrens participation in daily occupations in a variety of environments. The questionnaire was completed by the mothers of 41 children between the ages of 6 and 10 years (24 children with and 17 children without sensory modulation disorder). Cronbachs alpha varied from. 86 to. 89, indicating internal consistency of items. Test–retest reliability varied from. 69 to. 86, indicating that the instrument provides a stable measurement over time. The PICO-Q was found to differentiate between children with and without participation restrictions. The PICO-Q shows initial reliability and validity and has both research and clinical application potential.

The Influence of Environmental Factors on the Development of Ultra‐Orthodox Preschool Boys in Israel

The study objectives were: (a) to compare the prevalence of children at risk and/or with developmental delay (at risk/delayed) among the Ultra-Orthodox community with the prevalence reported in the literature and (b) to compare the performance of Ultra-Orthodox children in kindergarten versus that of children in preschool. To this end, motor, visual-motor integration and cognitive performance of 203 Ultra-Orthodox boys from low socio-economic status were assessed. We found a higher percentage of children who were at risk/delayed in gross motor and motor-cognitive skills as compared with the percentage reported in the literature. However, as opposed to expected, the results did not show that there was a higher percent of at-risk/delayed children among the kindergarten group as compared with those among the preschool group. Our findings are consistent with the research literature suggesting that childrens cultural background and economic constraints can affect their motor and cognitive development. Thus, occupational therapists and other health professionals should be more culturally competent and more aware of the specific values and practices of families of children with whom they work, which can impact their development. However, in this study, it is difficult to distinguish between the influence of the cultural factors and the influence of socio-economic factors. Therefore, it is recommended to repeat this study among children from either low socio-economic status or other cultural backgrounds.
