Insights from youth workers regarding young people's engagement in out-of-school-time youth development programs

L’objectif de cette étude exploratoire était de mieux comprendre, du point de vue des animateurs/animatrices qui oeuvrent auprès des jeunes, le phénomène de l’engagement des jeunes dans les programmes parascolaires. Des entretiens qualitatifs ont été entrepris à cette fin avec six animateur(trices). Plusieurs obstacles à l’engagement ont été identifiés, la plupart étant extérieurs aux jeunes. Quelques actions et attitudes spécifiques des animateur(trices) ont été relevées comme importantes pour aider les jeunes à surmonter ces obstacles. De plus, la structure et le contenu du programme, ainsi que l’environnement de groupe, jouent des rôles primordiaux. Les dimensions soulevées par les animateur(trices) ont permis d’enrichir et rendre plus holistique un modèle d’engagement qui a été développé à partir d’une recension des écrits dans ce domaine. Finalement, les implications pour la formation des animateurs(trices) et pour la structure des programmes pour les jeunes ont été explorées.

Reliability of a quantitative clinical posture assessment tool among persons with idiopathic scoliosis

Objective To determine overall, test–retest and inter-rater reliability of posture indices among persons with idiopathic scoliosis. Design A reliability study using two raters and two test sessions. Setting Tertiary care paediatric centre. Participants Seventy participants aged between 10 and 20 years with different types of idiopathic scoliosis (Cobb angle 15 to 60°) were recruited from the scoliosis clinic. Main outcome measures Based on the XY co-ordinates of natural reference points (e.g. eyes) as well as markers placed on several anatomical landmarks, 32 angular and linear posture indices taken from digital photographs in the standing position were calculated from a specially developed software program. Generalisability theory served to estimate the reliability and standard error of measurement (SEM) for the overall, test–retest and inter-rater designs. Bland and Altman's method was also used to document agreement between sessions and raters. Results In the random design, dependability coefficients demonstrated a moderate level of reliability for six posture indices (ϕ = 0.51 to 0.72) and a good level of reliability for 26 posture indices out of 32 (ϕ ≥ 0.79). Error attributable to marker placement was negligible for most indices. Limits of agreement and SEM values were larger for shoulder protraction, trunk list, Q angle, cervical lordosis and scoliosis angles. The most reproducible indices were waist angles and knee valgus and varus. Conclusions Posture can be assessed in a global fashion from photographs in persons with idiopathic scoliosis. Despite the good reliability of marker placement, other studies are needed to minimise measurement errors in order to provide a suitable tool for monitoring change in posture over time.
