Beyond p-values: A case for clinical relevance / Alisha Ohl in The British Journal of Occupational Therapy, Vol.80 Issue 12 (December 2017)

Public ISBD [article]  inThe British Journal of Occupational Therapy > Vol.80 Issue 12 (December 2017) . - p. 752-755 Titre : Beyond p-values: A case for clinical relevance Type de document : texte imprimé Auteurs : Alisha Ohl ; David Schelly Année de publication : 2017 Article en page(s) : p. 752-755 Langues : Anglais (eng) Mots-clés : méthodologie  statistique Résumé : There are inherent flaws to relying on p-values, or statistical significance, when assessing intervention effectiveness. Perhaps the biggest limitation to reporting and discussing statistically significant findings is that they do not necessarily translate to improvements that are perceptible or meaningful to patients. This opinion piece urges researchers to go beyond the prevailing standard of reporting p-values by using additional approaches that approximate clinical relevance; specifically anchor-based and distribution-based methods. To this end, we discuss the relative strengths and weaknesses of each method, and how they can not only be incorporated into existing data analyses but also inform future research design.

Effectiveness of a 10-week tier-1 response to intervention program in improving fine motor and visual-motor skills in general education kindergarten students / Alisha Ohl in American Journal of Occupational Therapy, Vol. 67/5 (septembre-octobre 2013)

Public ISBD [article]  inAmerican Journal of Occupational Therapy > Vol. 67/5 (septembre-octobre 2013) . - p.507-514 Titre : Effectiveness of a 10-week tier-1 response to intervention program in improving fine motor and visual-motor skills in general education kindergarten students Type de document : texte imprimé Auteurs : Alisha Ohl ; Hollie GRAZE ; Karen WEBER ; et al. Année de publication : 2013 Article en page(s) : p.507-514 Langues : Anglais (eng) Mots-clés : Pratique coopérative  Motricité  Performance  Psychomotricité  Service santé scolaire  Ecole maternelle  Enfant Résumé : OBJECTIVE: This study examined the efficacy of a 10-wk Tier 1 Response to Intervention (RtI) program developed in collaboration with classroom teachers to improve the fine motor and visual-motor skills of general education kindergarten students. METHOD: We recruited 113 students in six elementary schools. Two general education kindergarten classrooms at each school participated in the study. Classrooms were randomly assigned to the intervention and control groups. Fine motor skills, pencil grip, and visual-motor integration were measured at the beginning of the school year and after the 10-wk intervention. RESULTS: The intervention group demonstrated a statistically significant increase in fine motor and visual-motor skills, whereas the control group demonstrated a slight decline in both areas. Neither group demonstrated a change in pencil grip. CONCLUSION: This study provides preliminary evidence that a Tier 1 RtI program can improve fine motor and visual-motor skills in kindergarten students.

Test–Retest Reliability of the Child Occupational Self-Assessment (COSA) / Alisha Ohl in American Journal of Occupational Therapy, Vol. 69/2 (Mars/Avril 2015)

Public ISBD [article]  inAmerican Journal of Occupational Therapy > Vol. 69/2 (Mars/Avril 2015) . - p.1-4 Titre : Test–Retest Reliability of the Child Occupational Self-Assessment (COSA) Type de document : texte imprimé Auteurs : Alisha Ohl, Auteur ; Emily Crook, Auteur ; Diane MacSaveny, Auteur Année de publication : 2015 Article en page(s) : p.1-4 Langues : Anglais (eng) Mots-clés : Enfant  Activités vie quotidienne  AutoévaluationActivities of daily living  Patient outcome assessment  Reproducibility of results  Self concept  Self report Résumé : We examined the test–retest reliability of the Child Occupational Self-Assessment (COSA). Fifty-two children ages 6–12 yr completed the COSA on two separate occasions 7–14 days apart. Participant data were analyzed using intraclass correlation coefficients (ICCs). Test–retest reliability was good for total Competence and Value scores (ICC2,1 = .72–.77) and poor to good across category scores (ICC2,1 = .44–.78). These findings suggest that the children’s perceptions of their abilities and the value they placed on their everyday activities as reflected in the test items were fairly consistent over a short period of time.

Test–Retest Reliability of the Sensory Profile Caregiver Questionnaire / Alisha Ohl in American Journal of Occupational Therapy, Vol. 66/4 (juillet-aout 2012)

Public ISBD [article]  inAmerican Journal of Occupational Therapy > Vol. 66/4 (juillet-aout 2012) . - p. 483-487 Titre : Test–Retest Reliability of the Sensory Profile Caregiver Questionnaire Type de document : texte imprimé Auteurs : Alisha Ohl ; Cheryl BUTLER ; Christina CARNEY Année de publication : 2012 Article en page(s) : p. 483-487 Langues : Anglais (eng) Mots-clés : Questionnaire  Handicap sensoriel  Enfant Résumé : OBJECTIVE. We examined the test–retest reliability and internal consistency of the Sensory Profile Caregiver Questionnaire (SP). METHOD. Fifty-five primary caregivers of children 36–72 mo old participated in the study. Participants completed the SP on two separate occasions 7–14 days apart. Participant data were analyzed using intraclass correlation coefficients (ICCs) and Cronbach’s α coefficients. RESULTS. Test–retest reliability was good across quadrant scores (ICC[2, 1] = .80–.90) and moderate to good across factor (ICC[2, 1] = .69–.88) and section scores (ICC[2, 1] = .50–.87). Internal consistency was high across quadrant (αs = .89–.95) and factor scores (αs = .82–.93) and moderate to high across section scores (αs = .67–.93). CONCLUSION. This study suggests the SP has acceptable test–retest reliability and internal consistency and supports the use of quadrant scores over factor and section scores to analyze children’s sensory processing patterns Permalink : ./index.php?lvl=notice_display&id=14249 [article] Test–Retest Reliability of the Sensory Profile Caregiver Questionnaire [texte imprimé] / Alisha Ohl ; Cheryl BUTLER ; Christina CARNEY . - 2012 . - p. 483-487.
