What is a good correlation coefficient for validity, L. DOI: Patients who did not show any change on any of the 4 variables were considered stable and were used to evaluate test-retest reliability. Introduction What are the fundamental things in life pain is one of the most common problems affecting the lives of individuals and societies 1. Sleep apnea as an independent risk factor for all-cause mortality, The Busselton Health Study. A Chinese version of the Sleep Apnea Quality of Life Index was evaluated for reliability, validity, and responsiveness.

Objectives: To determine the test-retest reliability of a questionnaire, with a validation preliminary, to assess knowledge of cardiovascular risk CVR and cardiovascular disease in patients attending community pharmacies in Spain. To complement the external validity, establishing the relationship between an educational activity and the increase in what is body composition determined by about CVR and cardiovascular disease.

Location: Spanish Community Pharmacies. Participants: There were patients in the control group, from the who completed the study. Main measurements: Intraclass correlation coefficient to assess the reliability in 3 comparisons post-educational activity with week 16, post-educational activity with week 32, and week 16 with week 32 ; and the non-parametric Friedman test to establish the relationship between an oral and written educational correlatoin with increasing knowledge.

Results: For the patients in the 3 comparisons, which relaxer is good for afro hair intraclass correlation coefficient values were 0. Conclusions: According what is a good correlation coefficient for validity the intraclass correlation coefficient, the questionnaire aimed at assessing the knowledge on CVR and cardiovascular disease has a reliability between acceptable and excellent, which added to the previous validation, shows that the instrument meets the criteria of validity and reliability.

Furthermore, the questionnaire showed the ability to relate an increase in knowledge with an educational intervention, feature that complements its external validity. Objetivos: Determinar xorrelation fiabilidad test-retest de un cuestionario, con validación preliminar, para valorar el conocimiento sobre riesgo cardiovascular RCV y enfermedad cardiovascular, en pacientes atendidos en farmacias comunitarias de España. Complementar la validez externa, estableciendo la relación entre una actividad educativa y vallidity aumento del conocimiento sobre RCV y enfermedad cardiovascular.

Emplazamiento: Farmacia comunitaria española. Participantes: Trescientos veintitrés pacientes del grupo control, de los que finalizaron el estudio. Mediciones principales: Coeficiente de correlación intraclase para evaluar la fiabilidad en 3 comparaciones postactividad educativa con semana 16, postactividad educativa con semana 32, y semana 16 con semana 32 ; y prueba no paramétrica de Friedman para establecer la relación entre una actividad educativa oral y escrita con el aumento del conocimiento.

Resultados: Para los pacientes, en las 3 comparaciones, los valores del coeficiente de correlación intraclase fueron 0,; 0, y 0, fiabilidad what is a good correlation coefficient for validity a excelente. Conclusiones: Acorde ehat el coeficiente de correlación intraclase, el cuestionario orientado a valorar el conocimiento sobre el RCV y enfermedad cardiovascular tiene una fiabilidad entre aceptable y excelente, lo cual, sumado a la validación previa, indica que dicho instrumento cumple los criterios de validez y fiabilidad.
