Transcultural Validation of the Physical Activity Scale for Individuals With Physical Disabilities (PASIPD) in French: The PASIPD-Fr

Study Overview
=================
Brief Summary
-----------------
The Physical Activity Scale for Individuals With Physical Disabilities (PASIPD) is a scale that has been developped and validated in English to quantify the level of physical activity for people with physical disabilities. The investigators aimed to translate and validate a French transcultural version of the PASIPD (PASIPD-Fr) through a rigourous process following international recommendations for cross-cultural translation and adaptation of questionnaires.

Detailed Description
-----------------
For the translation, permission to proceed was obtained, and translation was conducted in consultation with the developers. The investigators proceed to a first translation of the initial scale from English to French with two French native bilingual physicians that resulted in a unique french translation. An English native bilingual physicians proceeded to a back translation from French to English. This version have been sent to the developers who agreed that this back translated version was faithful to the original scale. For the validation, the investigators used the international recommendations for cross-cultural translation and adaptation of questionnaires. Population was individuals with neurological disease (stroke, multiple sclerosis, Parkinson disease and neuromuscular disorders) with significant in physical disability. Patients were invited in an ambulatory setting. Data collected for every participant included demographic and general variables (age, sex, level, cause and time since neurological disease, walking capacities and aid), scores of a physical performance tests (10 Meter Walking Test, 10 MWT) and the 4 self-administered questionnaires: the Dijon Physical Activity Scale (PAS) the Activities-specific Balance Confidence (ABC) Scale, the Medical Outcome Study Short Form 12  (MOS SF-12) and the Hospital Anxiety and Depression (HAD) scale. Face validity was assessed using verbal feedbacks from physician and patients, and the mean time to fill-out the scale. Criterion validity was assessed with correlation and discrimination analysis between the scores for the PASIPD-Fr and the Dijon PAS. Construct validity was assessed using the correlation with scores of instruments that measure various aspects related to and physical activity (convergent validity) such as the self-reported questionaires ABC, SF-12 and HAD scales and also the 10 MWT. For consistency and reliability, the investigators calculated the Cronbach α coefficient and calculated the ICC between 2 completions at a 2-week interval. Sample calculation was based on an expected ICC > 0.9, which required 50 participants to reject the hypothesis that the actual ICC is < 0.6, which corresponds to the lower limit for a good reproducibility.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Criterion validity (correlation) | The Dijon PAS assesses the level of physical activity in the general population, the elderly and is recommended after a stroke. To test the criterion validity of the PASIPD-Fr, the investigators calculated the Pearson correlation coefficient (PCC) between the scores for the PASIPD-Fr and the Dijon PAS. | Both scales (PASIPD-Fr and Dijon PAS) were filled-out in a single point of time within a period of time of 12 months (study time frame) | 
| Criterion validity (discrimination) | The Dijon PAS assesses the level of physical activity in the general population, the elderly and is recommended after a stroke. To test the criterion validity of the PASIPD-Fr, the investigators used the repeated measures ANOVA to check for differences between inactive, moderately active ang highly active individuals (respectively score <10, 10-20 and >20 over 30 on Dijon PAS) with Tukey post-hoc tests. | Both scales (PASIPD-Fr and Dijon PAS) were filled-out in a single point of time within a period of time of 12 months (study time frame) | 
| Test-retest reliability | The investigators calculated the intraclass coefficient (ICC) between 2 completions of the PASIPD-Fr questionnaire at a 2-week interval. | The PASIPD-Fr was administered twice at a 2-week interval within a period of time of 12 months (study time frame) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Construct validity 10TMWT | The 10 Meter Walk Test is is a performance measure used to assess walking speed in metres per second over a short distance.To test the criterion validity of the PASIPD-Fr, the investigators calculated the Pearson correlation coefficient (PCC) between the scores for the PASIPD-Fr and the 10MWT | Both PASIPD-Fr questionaire and 10MWT test were assessed in a single point of time within a period of time of 12 months (study time frame) | 
| Construct validity ABC-S | The Activities-specific balance confidence (ABC) scale is a subjective measure of confidence in performing various ambulatory activities without experiencing a sense of unsteadiness.To test the criterion validity of the PASIPD-Fr, the investigators calculated the Pearson correlation coefficient (PCC) between the scores for the PASIPD-Fr and the ABC-S | Both PASIPD-Fr questionaire and ABC-S scale were filled-out in a single point of time within a period of time of 12 months (study time frame) | 
| Construct validity HAD | The Hospital Anxiety and Depression scale (HAD) is used to determine the levels of anxiety and depression that a person is experiencing. To test the criterion validity of the PASIPD-Fr, the investigators calculated the Pearson correlation coefficient (PCC) between the scores for the PASIPD-Fr and the HAD | Both PASIPD-Fr questionaire and HAD scale were filled-out in a single point of time within a period of time of 12 months (study time frame) | 
| Construct validity MOS SF12 | The Medical Outcome Study Short Form 12  (MOS SF-12) is used to measure mental and physical health. To test the criterion validity of the PASIPD-Fr, the investigators calculated the Pearson correlation coefficient (PCC) between the scores for the PASIPD-Fr and the MOS SF12 | Both PASIPD-Fr questionaire and MOS SF12 scale were filled-out in a single point of time within a period of time of 12 months (study time frame) | 
| Internal consistency | To measure the internal consistency (homogeneity) of the PASIPD-Fr, based on average inter-item correlations and the number of items. | The PASIPD-Fr scale was filled-out in a single point of time within a period of time of 12 months (study time frame) |
