Understanding and validating accelerometry as a measure of physical activity in children with intellectual disabilities

Background Physical activity in children with intellectual disabilities is a neglected area of study, which is most apparent in relation to physical activity measurement research. Although objective measures, specifically accelerometers, are widely used in research involving children with intellectual disabilities, existing research is based on measurement methods and data interpretation techniques generalised from typically developing children. However, due to physiological and biomechanical differences between these populations, questions have been raised in the existing literature on the validity of generalising data interpretation techniques from typically developing children to children with intellectual disabilities. Therefore, there is a need to conduct population-specific measurement research for children with intellectual disabilities and develop valid methods to interpret accelerometer data, which will increase our understanding of physical activity in this population. Methods Study 1: A systematic review was initially conducted to increase the knowledge base on how accelerometers were used within existing physical activity research involving children with intellectual disabilities and to identify important areas for future research. A systematic search strategy was used to identify relevant articles which used accelerometry-based monitors to quantify activity levels in ambulatory children with intellectual disabilities. Based on best practice guidelines, a novel form was developed to extract data based on 17 research components of accelerometer use. Accelerometer use in relation to best practice guidelines was calculated using percentage scores on a study-by-study and component-by-component basis. Study 2: To investigate the effect of data interpretation methods on the estimation of physical activity intensity in children with intellectual disabilities, a secondary data analysis was conducted. Nine existing sets of child-specific ActiGraph intensity cut points were applied to accelerometer data collected from 10 children with intellectual disabilities during an activity session. Four one-way repeated measures ANOVAs were used to examine differences in estimated time spent in sedentary, moderate, vigorous, and moderate to vigorous intensity activity. Post-hoc pairwise comparisons with Bonferroni adjustments were additionally used to identify where significant differences occurred. Study 3: The feasibility on a laboratory-based calibration protocol developed for typically developing children was investigated in children with intellectual disabilities. Specifically, the feasibility of activities, measurements, and recruitment was investigated. Five children with intellectual disabilities and five typically developing children participated in 14 treadmill-based and free-living activities. In addition, resting energy expenditure was measured and a treadmill-based graded exercise test was used to assess cardiorespiratory fitness. Breath-by-breath respiratory gas exchange and accelerometry were continually measured during all activities. Feasibility was assessed using observations, activity completion rates, and respiratory data. Study 4: Thirty-six children with intellectual disabilities participated in a semi-structured school-based physical activity session to calibrate accelerometry for the estimation of physical activity intensity. Participants wore a hip-mounted ActiGraph wGT3X+ accelerometer, with direct observation (SOFIT) used as the criterion measure. Receiver operating characteristic curve analyses were conducted to determine the optimal accelerometer cut points for sedentary, moderate, and vigorous intensity physical activity. Study 5: To cross-validate the calibrated cut points and compare classification accuracy with existing cut points developed in typically developing children, a sub-sample of 14 children with intellectual disabilities who participated in the school-based sessions, as described in Study 4, were included in this study. To examine the validity, classification agreement was investigated between the criterion measure of SOFIT and each set of cut points using sensitivity, specificity, total agreement, and Cohen’s kappa scores. Results Study 1: Ten full text articles were included in this review. The percentage of review criteria met ranged from 12%−47%. Various methods of accelerometer use were reported, with most use decisions not based on population-specific research. A lack of measurement research, specifically the calibration/validation of accelerometers for children with intellectual disabilities, is limiting the ability of researchers to make appropriate and valid accelerometer use decisions. Study 2: The choice of cut points had significant and clinically meaningful effects on the estimation of physical activity intensity and sedentary behaviour. For the 71-minute session, estimations for time spent in each intensity between cut points ranged from: sedentary = 9.50 (± 4.97) to 31.90 (± 6.77) minutes; moderate = 8.10 (± 4.07) to 40.40 (± 5.74) minutes; vigorous = 0.00 (± .00) to 17.40 (± 6.54) minutes; and moderate to vigorous = 8.80 (± 4.64) to 46.50 (± 6.02) minutes. Study 3: All typically developing participants and one participant with intellectual disabilities completed the protocol. No participant met the maximal criteria for the graded exercise test or attained a steady state during the resting measurements. Limitations were identified with the usability of respiratory gas exchange equipment and the validity of measurements. The school-based recruitment strategy was not effective, with a participation rate of 6%. Therefore, a laboratory-based calibration protocol was not feasible for children with intellectual disabilities. Study 4: The optimal vertical axis cut points (cpm) were ≤ 507 (sedentary), 1008−2300 (moderate), and ≥ 2301 (vigorous). Sensitivity scores ranged from 81−88%, specificity 81−85%, and AUC .87−.94. The optimal vector magnitude cut points (cpm) were ≤ 1863 (sedentary), ≥ 2610 (moderate) and ≥ 4215 (vigorous). Sensitivity scores ranged from 80−86%, specificity 77−82%, and AUC .86−.92. Therefore, the vertical axis cut points provide a higher level of accuracy in comparison to the vector magnitude cut points. Study 5: Substantial to excellent classification agreement was found for the calibrated cut points. The calibrated sedentary cut point (ĸ =.66) provided comparable classification agreement with existing cut points (ĸ =.55−.67). However, the existing moderate and vigorous cut points demonstrated low sensitivity (0.33−33.33% and 1.33−53.00%, respectively) and disproportionately high specificity (75.44−.98.12% and 94.61−100.00%, respectively), indicating that cut points developed in typically developing children are too high to accurately classify physical activity intensity in children with intellectual disabilities. Conclusions The studies reported in this thesis are the first to calibrate and validate accelerometry for the estimation of physical activity intensity in children with intellectual disabilities. In comparison with typically developing children, children with intellectual disabilities require lower cut points for the classification of moderate and vigorous intensity activity. Therefore, generalising existing cut points to children with intellectual disabilities will underestimate physical activity and introduce systematic measurement error, which could be a contributing factor to the low levels of physical activity reported for children with intellectual disabilities in previous research.

A Multidimensional Approach to Social Support: the Questionnaire on the Frequency of and Satisfaction with Social Support (QFSSS)

The Questionnaire on the Frequency of and Satisfaction with Social Support (QFSSS) was designed to assess the frequency of and the degree of satisfaction with perceived social support received from different sources in relation to three types of support: emotional, informational, and instrumental. This study tested the reliability of the questionnaire scores and its criterion and structural validity. The data were drawn from survey interviews of 2042 Spanish people. The results show high internal consistency (values of Cronbach's alpha ranged from .763 to .952). The correlational analysis showed significant positive associations between QFSSS scores and measures of subjective well-being and perceived social support, as well as significant negative associations with measures of loneliness (values of Pearson's r correlation ranged from .11 to .97). Confirmatory factor analysis using structural equation modelling verified an internal 4-factor structure that corresponds to the sources of support analysed: partner, family, friends, and community (values ranged from .93 to .95 for the Goodness of Fit Index (GFI); from .95 to .98 for the Comparative Fit Index (CFI); and from .10 to .07 for the Root Mean Square Error of Approximation (RMSEA)). These results confirm the validity of the QFSSS as a versatile tool which is suitable for the multidimensional assessment of social support.

Glasgow Psychosis Screening tool for use in adults with Intellectual Disabilities (GPS-ID): development and psychometric properties

Background: Prevalence of psychosis is known to be higher in adults with intellectual disabilities (ID) than in the general adult population. However, there have been no attempts to develop a psychosis screening tool specifically for the adult ID population. The present study describes the development and preliminary evaluation of a new measure, the Glasgow Psychosis Screening tool for use in Adults with Intellectual Disabilities (GPS-ID). Method: An item pool was generated following: 1) focus groups with adults with ID and psychosis, and their carers and/or workers; 2) expert input from clinicians. A draft scale was compiled and refined following expert feedback. The new scale, along with the Psychotic Symptom Rating Scales was administered to 20 adults with ID (10 with and 10 without psychosis) and their relative or carers. Results: The GPS-ID total score, self-report subscale and informant rating-subscale differentiated psychosis and non-psychosis groups. The tool had good internal consistency (Cronbach’s α=0.91), and a cut-off score ≥4 yielded high sensitivity (90%) and specificity (100%). The method of tool development supports face and content validity. Criterion validity was not supported. Conclusions: Preliminary investigation of the tool’s psychometric properties is positive, although further investigation is required. The tool is accessible to adults with mild to moderate ID and can be completed in 15-30 minutes. The GPS-ID is not a diagnostic tool, therefore any adult exceeding the cut-off score of ≥4 should receive further assessment.

Young people with learning disabilities who sexually harm others: the role of criminal justice within a multi-agency response

This paper outlines the key findings from a recent study of statutory service responses to young people with learning disabilities who show sexually inappropriate or abusive behaviours, with a particular focus on the involvement of criminal justice agencies. The study found that although inappropriate sexual behaviours were commonplace in special schools, and that serious acts of abuse including rape had sometimes occurred, education, welfare and criminal justice agencies struggled to work together effectively. In particular, staff often had difficulty in determining the point at which a sexually inappropriate behaviour warranted intervention. This problem was frequently compounded by a lack of appropriate therapeutic services. In many cases this meant that no intervention was made until the young person committed a sexual offence and the victim reported this to the police. As a consequence, young people with learning disabilities are being registered as sex offenders. The paper concludes by addressing some of the policy and practice implications of the study’s findings, particularly those which relate to criminal justice.

CHARACTERISTICS OF PRIVATE HIGH SCHOOLS FOR STUDENTS WITH EMOTIONAL DISABILITIES AND PERCEPTIONS OF THEIR PUBLIC SCHOOL CASE MANAGERS

Placement of students with disabilities in private special-education schools remains costly and controversial. This is particularly concerning, given the lack of research on the characteristics and quality of these restrictive settings. The purpose of this study was to identify the academic and vocational course offerings and behavioral supports provided in private special-education schools the serve high school students with emotional disabilities (ED). Second, the research examined the perceptions of the quality of services in these setting from the perspectives of public school case managers. Using a mixed-method design to collect data, 9 administrative heads of private special-education schools were surveyed, and 7 public school case managers were interviewed. Results indicated that (a) private special-education schools offer the basic academic core courses needed to meet graduation requirements, (b) vocational options for students enrolled in these schools are quite limited, (c) these schools provide a variety of behavioral interventions and supports, and (d) case managers are concerned with the lack of academic rigor and inconsistent programming at these schools but applauded the notion that students with ED are exiting with a high school diploma. Findings from this study may have policy implications for improving and developing programming options for high school students with ED.

Factors contributing to defaulting scheduled therapy sessions by caregivers of children with congenital disabilities

Background Defaulting scheduled rehabilitation therapy may result in increased adverse outcomes such as permanent disability and increased healthcare costs. Concomitantly, there is evidence to suggest that early and continued rehabilitation of children with congenital disabilities can improve outcomes significantly. This study was conducted to determine factors contributing to caregivers’ defaulting scheduled rehabilitation therapy sessions. Methods A descriptive cross sectional study was carried out at Chitungwiza Central Hospital, a tertiary facility offering in and outpatient rehabilitation services in Zimbabwe. Caregivers of children who had congenital disabilities (N=40) and who had a history of defaulting treatment but were available during the data collection period responded to an interviewer administered questionnaire. Data were analysed for means and frequencies using STATA 13. Results Factors that contributed to caregivers defaulting scheduled therapy included economic constraints (52%), child related factors (43%), caregiver related factors (42%), service centred factors (30%) and psychosocial factors (58%). Majority of the caregivers (98%) were motivated to attend therapy by observable improvements in their children. Other motivators were incentives given in the rehabilitation department (45%), availability of rehabilitation personnel to provide the required services (48%) and psychosocial support from fellow caregivers, families and the rehabilitation staff (68%). Although all the caregivers could not distinguish occupational therapy from physiotherapy services they all reported that therapy was important. Conclusions A combination of psychosocial, economic, child centred and service centred factors contributed to caregivers defaulting scheduled therapy. Interventions that may potentially improve caregiver attendance to scheduled therapy include community outreach services, efficient rehabilitation service provision at the hospitals, and facilitation of income generating programmes for caregivers.

Exploring value creation with Social Media use in hotels

En la última década las tecnologías de Social Media han revolucionado el entorno competitivo, reinventando la forma de relacionarse con los clientes. En el sector hotelero, hoteles de todo el mundo están usando dichas herramientas para atraer a los clientes, estableciendo conversaciones colaborativas con ellos que vayan forjando vínculos emocionales con la marca. Asimismo, los hoteles se han dado cuenta de que herramientas Social Media se han convertido en facilitadoras de estrategias CRM (Gestión de Relaciones con Clientes), por lo que están integrando el uso de ambas herramientas para conocer mejor a sus clientes. No obstante, a pesar de la gran relevancia y del uso generalizado de Social CRM, la eficacia de dichas herramientas y su impacto en la creación de valor han sido aspectos poco analizados en estudios previos. Asimismo, la escasa investigación existente parece indicar que los hoteles no están aprovechando todo su potencial transformador. Con objeto de explorar la temática, el presente trabajo propone un marco teórico en el que se analiza cómo los hoteles pueden beneficiarse del uso de Social Media (uso de redes sociales y de sitios de revisión), examinando su impacto en resultados e introduciendo el papel mediador de las capacidades de gestión de relación con clientes usando Social Media. El trabajo supone una primera aproximación teórica al fenómeno, y constituye una base para la realización de futuros análisis empíricos.

Repeated Reading Strategy for Students with Intellectual Disabilities

Repeated Reading Strategy used with Intellectually Disabled Students in order to increase reading fluency and comprehension.

Repeated Readings to Promote Fluency for Students with Intellectual Disabilities

Reading fluency is a skill that’s difficult for many students to acquire. However, research suggests that consistently implementing the Repeated Reading intervention can help students increase fluency and comprehension. The effect of this strategy when used to promote reading fluency in secondary students with severe intellectual disabilities has yet to be investigated. My research will examine the effect of the Repeated Reading intervention on the fluency level of students with intellectual disabilities in a public high school.

Family as the Promoter of Independence Skills in Children with Motor Disabilities

This study developed an individualized proposal to promote, from the family context, the independence of two four-year-old children with motor disabilities. The proposal aimed at helping mothers and fathers to promote different skills within the family context. The results of this study revealed that when the families of children with disabilities are oriented, it is easier for them to start processes that otherwise would be postponed. As a result, it is recommended to create proposals to support the parents and help them to build their own family-growth processes and develop independence living skills in their children with motor disabilities.

Cahier des charges fonctionnel pour la conception et l’évaluation des plans d’intervention

La politique québécoise de l’adaptation scolaire confirme que le plan d’intervention (PI) constitue l’outil privilégié pour répondre aux besoins des élèves handicapés ou en difficulté d’adaptation ou d’apprentissage. Toutefois, la recension des écrits nous informe que le plan d’intervention est encore loin d’être efficace. Le Ministère de l’Éducation, des Loisirs et des Sports du Québec (MELS, 2004) ainsi que l’Office of Special Education and Rehabilitative Services des U.S. department of Education (dans Eichler, 1999) ont bien identifié et présenté explicitement cinq à six fonctions du PI mais, aucun des deux organismes ne définit ce qu’est une fonction, à quoi elle sert, son importance relative et ce qu’elle implique. De plus, on retrouve, explicitement ou implicitement, soit dans le cadre de référence pour l’établissement des PI (MELS, 2004), soit dans la revue de la littérature, soit dans les milieux de pratique plusieurs autres fonctions que le PI remplit ou devrait remplir. Ce flou entourant le concept de fonction entraîne un manque de rigueur dans la conception des PI, car « lorsque la totalité des fonctions a été identifiée, elle permet le développement d’un produit répondant à l’usage attendu » (Langevin et coll., 1998). Il y a d’emblée une somme de fonctions qu’un PI remplit déjà et d’autres sûrement à remplir. Or, cela n’a pas été élucidé, précisé et validé. Le but de la présente recherche a été de définir les rôles du PI au regard des besoins de ses différents utilisateurs. Les objectifs spécifiques ont été les suivants, 1) Identifier les différents utilisateurs d’un PI, 2) Identifier les besoins des différents utilisateurs d’un PI, 3) Identifier les fonctions qu’un PI doit remplir afin de satisfaire les besoins de ses utilisateurs, 4) Créer un cahier des charges fonctionnel pour la conception et l’évaluation d’un PI, 5) Identifier certains coûts reliés à la conception d’un PI. Afin d’atteindre les objectifs précités, nous avons eu recours à la méthode de l’analyse de la valeur pédagogique (AVP) (Langevin, Rocque et Riopel, 2008). La méthode d’AVP comportait une analyse des besoins des différents utilisateurs potentiels, une analyse de la recension des écrits, une analyse des encadrements légaux, une analyse de produits types et une analyse écosystémique. En conclusion, nous avons identifié les différents utilisateurs potentiels d’un PI, identifié les différents besoins de ces utilisateurs, identifié les fonctions qu’un PI doit remplir pour satisfaire leurs besoins, crée un cahier des charges fonctionnel (CdCF) pour la conception et l’évaluation des PI et identifié certains coûts liés à la conception d’un PI. Le CdCF pourra servir à concevoir des PI et à évaluer leur efficience. Une partie du CdCF pourra aussi remplir un rôle prescriptif pour la conception d’outil de soutien à l’élaboration du PI. Enfin, le CdCF pourra servir à la formation et à la recherche en éducation.

Exploration du lien entre les dynamiques sociales et les perceptions de l’activité physique chez de jeunes Québécois de 12-14 ans

Au début de l’adolescence, on observe une diminution marquée du niveau de pratique d’activité physique (PAP). Les pairs ont été identifiés comme des déterminants importants de la PAP à cette période de la vie. Notre étude explore le rôle des dynamiques sociales entre les pairs dans les perceptions de la PAP d’adolescents Québécois. Des entretiens semi-directifs ont été réalisés auprès de 12 garçons et 10 filles, âgés entre 12 et 14 ans, issus de trois écoles aux profils socioéconomiques, géographiques (urbain, de banlieue et rural) et ethniques différents. Le guide d’entretien abordait les thèmes de l’amitié, des railleries, des émotions et des interactions sociales vécues dans différents contextes de PAP. Une analyse descriptive des entretiens a été effectuée afin d’identifier les éléments des dynamiques sociales susceptibles d’influencer les perceptions de la PAP dans différents contextes. L’environnement social des cours d’éducation physique (compétences physiques variées, mixité, valorisation de la compétition) semble favoriser des relations inégales et des rapports de pouvoir entre les jeunes. Les perceptions des adolescents concernant ce contexte de pratique sont souvent négatives. Les perceptions favorables à l’activité physique sont plutôt liées à des contextes de pratique que l’on retrouve à l’extérieur du milieu scolaire et où l’environnement social semble favoriser l’émergence de relations d’égal à égal (compétences physiques similaires, groupes de pairs du même sexe). Les résultats de cette étude peuvent guider les intervenants dans la mise en place de conditions d’intervention qui pourront favoriser la pratique d’activité physique.
