Development, reliability, and validity of the Sensory Adventure Measure.

INTRODUCTION: Sensory modulation refers to a condition in which an individual's behavioural responses to sensory stimuli do not correspond to the nature or intensity of the stimuli. Sensory modulation affects children's participation in everyday activities and their well-being. The most common assessments used are caregiver questionnaires. Our aim is twofold; first to develop a clinical evaluative measure, the Sensory Adventure Measure (SAM), for directly assessing sensory modulation in children via therapists and children's self-report, second, we aim to establish its reliability and validity. METHODS: The study sample comprised 87 children ranging in age from 4 to 6 years and 11 months old divided into two groups: study group included 63 children with mild developmental disabilities and the control group included 24 typically developed children. The SAM's internal consistency, test-retest reliability, and inter-rater reliability were examined. In addition, criterion validity was established using the total score of the Short Sensory Profile (SSP) and construct validity was established by known group differences. RESULTS: The SAM exhibited good internal consistency (α = 0.83, 0.85) and moderate to very good test-retest reliability (r = 0.96, 0.98, 0.75). Inter-rater reliability was strong (r = 0.80-0.83). Moderate correlation was found between the SAM Therapist Rating of Magnitude total score and the total score of the SSP and significant differences were found in the SAM scores between groups thus establishing validity. CONCLUSIONS: The SAM demonstrated good psychometric properties and can be used as a reliable and valid measure to assess sensory modulation among children aged 4 to 6 years. The SAM can be used by therapists to assess sensory modulation disorder based on observed responses to sensory stimuli and the child's self-report. The SAM contributes additional perspective to the evaluation process of sensory modulation disorder.

Pressure distributions on the chair seat and backrest correlate with handwriting outcomes of school children.

BACKGROUND: Postures while sitting are believed to have an important influence on the process of writing and quality of handwriting, but data in this field are sparse. OBJECTIVES: The current study was undertaken to investigate correlations between 'ordinary' children's handwriting skills and their posture and stability while sitting. METHODS: Twenty-nine children with typical development (age 9.2±0.8 years) underwent the Hebrew Handwriting Evaluation, while the pressure distributions on their seats and backrests were recorded using a pressure mapping system. RESULTS: There was an increase in the odds of erasing and overwriting letters in dictation tasks when body displacements of the buttocks increased [Odds Ratio (OR) = 1.01, 95% CI 1.000-1.02, p = 0.050]. Children who did not lean on the backrest were more likely to have legible handwriting in copying tasks (OR = 0.136, 95% CI 0.026-0.723, p = 0.019). CONCLUSIONS: The awareness and involvement of health practitioners in sitting postures of children at school might promote activities such as writing. Further investigation of movement patterns while writing and of the correlations of these patterns with handwriting outcomes is recommended. More research regarding adjustments at the school environment for children with developmental disorders is also warranted.

The profile of performance skills and emotional factors in the context of participation among young children with Developmental Coordination Disorder.

Participation is a person's involvement in daily activities in a variety of environments, roles and life situations. Children with Developmental Coordination Disorder (DCD) experience difficulties in gaining academic achievements or in their engagement in activity of daily living. Motor difficulties have a negative effect on the ability to participate, as well as on various affective components. Senses of coherence, effort and hope have not yet been assessed, within the context of participation, in children with DCD. The purpose of the present study is to look into the relations between participation and senses of coherence, effort and hope among children with DCD, in comparison to typically developed children. Fifty subjects aged 5-6 years participated in the study, 25 of whom are children diagnosed with DCD, the other 25 being typical children. The DCD diagnosis was established according to the DSM-IV criteria and the M-ABC test. All children completed the coherence questionnaire for children as well as the children's questionnaire on effort and hope. Parents completed the Children Participation Questionnaire (CPQ), and the Performance Skills Questionnaire (PSQ). Children with DCD had lower performance skills, lower sense of coherence, hope, and effort than their peers. They less enjoy their participation and their parents are less satisfied in comparison to control group. Significant correlations were found between sense of coherence and hope to participation. Process skills were found to be the main predictor for explaining child's participation. While treating children with DCD we have to consider also socio-psychological aspects that may be weakened.
