Insights
The Arabic EPInfant scale (EPInfant-Ar) is a valid and reliable tool for measuring perceived exertion in children aged 6-16. This new scale accurately assesses children's physical exertion levels after exercise.
Area of Science:
- Pediatric Exercise Science
- Psychometrics
- Health Sciences
Background:
- Perceived exertion (PE) is crucial for monitoring children's physical activity.
- The EPInfant scale measures PE in children during exercise.
- Translating and validating the EPInfant scale into Arabic is necessary for its use in Arabic-speaking populations.
Purpose of the Study:
- To translate the EPInfant scale into Arabic (EPInfant-Ar).
- To evaluate the psychometric properties of the EPInfant-Ar scale.
- To establish the validity and reliability of the EPInfant-Ar for assessing PE in children.
Main Methods:
- The EPInfant scale was translated into Arabic.
- Face and content validity were assessed by experts.
- Concurrent validity was tested by correlating PE with heart rate (HR) and oxygen saturation during a 3-minute step test in 93 children.
- Internal consistency and test-retest reliability were evaluated using Cronbach's alpha and intraclass correlation coefficient (ICC).
Main Results:
- Content validity demonstrated excellent expert agreement.
- A moderate correlation was found between EPInfant-Ar ratings and HR (r=0.47, p < .001).
- Acceptable internal consistency (α=0.89) and test-retest reliability (ICC=0.81) were observed, with low measurement error (MDC95=2.66).
Conclusions:
- The EPInfant-Ar scale is a valid and reliable instrument.
- It can be effectively used to assess perceived exertion in typically developing Arabic-speaking children aged 6-16 years.
- This validated Arabic scale supports accurate PE monitoring in pediatric populations.
Aims:
The EPInfant scale is a self-assessment for children that measures perceived exertion (PE) during physical exercise. This study aimed to translate the scale into Arabic (EPInfant-Ar) and test its psychometric properties.
Methods:
The revised version was tested for face and content validity. Oxygen saturation, heart rate (HR), and ratings of perceived exertion were measured during a 3-minute step test with a sample of 93 children. PE and HR were examined using the Pearson correlation coefficient (r) to assess the concurrent validity. Internal consistency and test-retest reliability were calculated using Cronbach's alpha (α), intraclass correlation coefficient (ICC2,1), and r coefficient. A minimum detectable change with 95% confidence interval (MDC95) and percentage of change (MDC%) was also measured.
Results:
Content validity showed an excellent level of expert agreement. There was a moderate correlation between PE rated by the scale and HR (r = 0.47, p < .001). The internal consistency and test-retest reliability were acceptable (α = 0.89; ICC2,1= 0.81; 95%Cl: 0.71-0.87, r = 0.81) with low measurement error (MDC95 = 2.66 and MDC% = 61.10%).
Conclusions:
The EPInfant-Ar scale was considered valid and reliable for assessing PE after physical exercises in typically developing children aged 6-16 years.
