Measures of frequency used in cohorts studies to evaluate the suicidal behaviour in young people (12-26 years): A systematic review. / Medidas de frecuencia utilizadas en estudios de cohortes para evaluar el comportamiento suicida en jóvenes (12-26 años): una revisión sistemática.

INTRODUCTION: A priority for the WHO by 2020 is to have reduced the rates of suicide; they indicate difficulties in giving precise estimations due to a wide variety of factors, which include aspects related to the statistical measurements themselves of suicidal behaviour. The proportion of deaths from suicide is 8.5% among young people between 15-29 years of age. OBJECTIVE: To review the methodology used to express the frequency of suicidal behaviour in young people and to describe the methodological characteristics of the studies reviewed. METHOD: A systematic review of longitudinal studies registered on PROSPERO. The extracted information included the following: year of publication, journal, population size, sample, country, design, age, percentage of men, follow-up time and losses, suicidal behaviour, risk factors, ethical aspects, fundamentally, evaluating the measures of frequency used. RESULTS: Eighty-two articles were selected from 37,793 documents. None of the studies define the measure of frequency used for suicidal behaviour, there are currently up to 9 different ways of measuring it. The populations are students or the general population (66%), birth cohorts (16%) and specific groups. Follow-up was from 24 weeks to 30 years. Only 24.1% of the studies took ethical aspects into consideration. CONCLUSIONS: Researchers must make an effort to reach an agreement on the measures of frequency used in suicidal behaviour studies, as the methodological and terminological variability currently used impedes making any comparisons between different studies or understanding the real dimension of the problem.

[Evaluation of patient satisfaction after stroke rehabilitation program. Validation study for the Spanish version of the Satisfaction Pound Scale]. / Evaluación de la satisfacción con el programa de rehabilitación tras el ictus: validación de la versión española de la Pound Satisfaction Scale.

BACKGROUND AND OBJECTIVE: The Satisfaction Pound Scale is a specific questionnaire to evaluate satisfaction with the rehabilitation program after a stroke. The aim of this study was to adapt this scale to Spanish and to evaluate its metric characteristics. METHOD: The adaptation included translation and back-translation methods. Metric characteristics were evaluated in 74 patients, all of whom were administered the Satisfaction Pound Scale and the Short Form 36 (SF-36). The statistical model was tested by confirmatory factor analysis (CFA). Reliability was determined through Cronbach alpha coefficient and a test-retest procedure. Construct validity was assessed by means of correlations between the satisfaction scale and the SF-36. RESULTS: Adjustment indicators in the CFA were very good. Reproducibility test showed correlations higher than 0.85, and all correlations between SF-36 dimensions and the satisfaction scale were lower than 0.2, in accordance with the hypotheses raised. CONCLUSIONS: The Spanish version of the Satisfaction Pounds Scale is reliable and valid, therefore it is a useful tool to assess satisfaction with the post-stroke rehabilitation program in our area.

Introducción: La OMS prioriza para el año 2020 reducir las tasas de suicidio señalando dificultades para dar estimaciones precisas debido a una amplia variedad de factores, entre ellos, aspectos relativos a la propia medición estadística de la conducta suicida. La proporción de muertes por suicidio es del 8,5% para los jóvenes de entre 15-29 años. Objetivo: Revisar la metodología empleada para expresar la frecuencia de la conducta suicida en población joven y describir las características metodológicas de los estudios examinados. Método: Revisión sistemática de estudios longitudinales registrada en PROSPERO. La información extraída fue: año de publicación, revista, tamaño poblacional, muestra, país, diseño, edad, porcentaje de hombres, tiempo de seguimiento y pérdidas, comportamiento suicida, factores de riesgo, aspectos éticos y evaluándose fundamentalmente las medidas de frecuencia empleadas. Resultados: Se identificaron 37.793 documentos, de los cuales fueron seleccionados 82. Ningún estudio define la medida de frecuencia empleada para la conducta suicida, encontrándose hasta 9 formas diferentes de medirla. La población son estudiantes o población general (66%), cohortes de nacimiento (16%) y colectivos específicos. El seguimiento fue de 24 semanas hasta 30 años. Solo un 24,1% de los estudios consideró los aspectos éticos. Conclusiones: Se constata que no existe una sistematización a la hora de medir la frecuencia de presentación de la conducta suicida. La variabilidad metodológica y terminológica utilizada dificulta hacer comparaciones entre los estudios y conocer la verdadera dimensión del problema. Se insta a los investigadores a realizar un esfuerzo para consensuar las medidas de frecuencia empleadas en los estudios de cohortes

Evaluación de la satisfacción con el programa de rehabilitación tras el ictus: validación de la versión española de la Pound Satisfaction Scale / Evaluation of patient satisfaction after stroke rehabilitation program. Validation study for the Spanish version of the Satisfaction Pound Scale

Fundamento y objetivo. La Escala de Satisfacción de Pound es un cuestionario específico para evaluar la satisfacción con la rehabilitación seguida tras el ictus. Nuestro objetivo fue adaptar esta escala al español y evaluar sus características métricas. Método. La adaptación se realizó por traducción-retrotraducción. Las características métricas se evaluaron en 74 pacientes con la Escala de Satisfacción de Pound y el cuestionario de salud percibida Short Form 36 (SF-36). El modelo de medida se evaluó mediante análisis factorial confirmatorio (AFC); la fiabilidad, a partir de la consistencia interna y la reproducibilidad (test-retest); la validez de constructo se estudió mediante las correlaciones entre la escala de Pound y el SF-36. Resultados. Los indicadores de bondad de ajuste del AFC fueron muy buenos. En el estudio test-retest los coeficientes de correlación intraclase fueron>0,85. Todas las correlaciones entre las dimensiones del SF-36 y el cuestionario de satisfacción fueron<0,2. Conclusiones. La versión en español de la Escala de Satisfacción de Pound administrada telefónicamente es fiable y válida, resultando útil para evaluar la satisfacción con la rehabilitación seguida tras el ictus (AU)
