Escala de Felicidad Subjetiva: Análisis de sus propiedades psicométricas / Subjective Happiness Scale: Analysis of your psychometric properties

Resumen El análisis de las propiedades psicométricas de la Escala de Felicidad Subjetiva ha reportado datos que indican problemas con el ítem 4, lo que ha conducido a algunos autores a plantear una supresión hipotética del mismo. Este ítem, formulado en términos negativos y comparativos de manera simultánea, aparece desde la versión original de la escala; sin embargo, las anomalías psicométricas informadas plantean la necesidad de analizar la pertinencia de una versión de tres ítems de la escala. En ese sentido, el presente estudio tiene como objetivo central comparar las propiedades psicométricas de dos versiones de la Escala de Felicidad Subjetiva (una de cuatro ítems y otra de tres ítems). Para el logro de este objetivo se llevó a cabo un estudio instrumental mediante el análisis de una base de datos configurada por 372 participantes, provenientes de cuatro estudios previos donde se aplicó dicha escala. Los resultados indican una superioridad de la versión de tres ítems de la escala al presentar un mayor nivel de confiabilidad y mejores valores en el Análisis Factorial Exploratorio y el Análisis Factorial Confirmatorio. Se recomienda el uso de la versión de tres ítems en población mexicana y analizar la pertinencia de aumentar la escala de valores de la posible respuesta.

Abstract The analysis of the psychometric properties of the Subjective Happiness Scale has reported data indicating problems with item 4, which has led some authors to propose a hypothetical suppression of it. This item, formulated in negative and comparative terms simultaneously, appears from the original version of the scale; however, the psychometric anomalies reported raise the need to analyze the relevance of a three-item version of the scale. In this sense, the present study has as a central objective to compare the psychometric properties of two versions of the Subjective Happiness Scale (one of four items and another of three items). To achieve this objective, an instrumental study was carried out by analyzing a database configured by 372 participants from four previous studies where this scale was applied. The results indicate a superiority of the three-item version of the scale by presenting a higher level of reliability and better values in the Exploratory Factor Analysis and Confirmatory Factor Analysis. It is recommended to use the three-item version in the Mexican population and analyze the relevance of increasing the scale of values of the possible response.

Avaliação psicométrica em português do indicador de dor crônica de Helsinki em cães com sinais crônicos de osteoartrite / Psychometric testing in Portuguese of Helsinki's chronic pain index for dogs with chronic signs of osteoarthritis

Objetivou-se determinar a validade, a confiabilidade e a sensibilidade do indicador de dor crônica de Helsinki (IDCH) em português, além de estabelecer correlação entre a plataforma de pressão em cães com displasia coxofemoral (DCF). O questionário foi preenchido por tutores de 40 animais com DCF e por 16 tutores de cães saudáveis. Os animais com DCF foram tratados com carprofeno 4,4mg/kg (GT= 21) ou placebo (GP= 19), administrados uma vez ao dia, durante quatro semanas. A avaliação consistiu no preenchimento do questionário (IDCH), na escala analógica visual de dor (EAVdor) e na escala analógica visual de locomoção (EAVloc) com duas semanas (A1) e imediatamente antes do tratamento (A2), duas (S2) e quatro (S4) semanas de tratamento e após duas semanas do término do tratamento (S6). A consistência interna dos dados foi considerada excelente (alfa de Cronbach = 0,89). Houve correlação moderada entre o IDCH e a EAVdor e boa entre o IDCH e a EAVloc, porém não houve diferença entre o grupo tratado com carprofeno e placebo no IDCH. Não houve correlação entre os dados da plataforma de pressão e o IDCH. O questionário apresentou validade de constructo, critério e fidedignidade e pode-se empregá-lo em países de língua portuguesa em cães com osteoartrite.(AU)

We aimed to determine validity, reliability, and sensitivity of Helsinki's chronic pain index (HCPI) and stablish a correlation between HCPI in dogs with hip dysplasia (HD) using pressure sensitive walkway. Forty-owners of dogs with HD and 16 owners of health dogs filled a questionnaire. Dogs with HD were treated with carprofen 4.4mg/kg (GT n= 21) or with placebo (GP n= 19), both were administered once a day for 4 weeks. Evaluation was performed by the owners using the questionnaire (HCPI), the Visual Analogue Scale for pain (VASpain) and the VAS for locomotion (VASloc). The evaluation was performed 2 weeks before the treatment began (A1), immediately after treatment (A2), two (S2), four (S4) and two weeks after the end of treatment (S6) and the lameness was evaluated by pressure sensitive walkway. The internal consistency of the data was considered excellent (Cronbach´α coefficient= 0.89). There was a moderate correlation between the HCPI and VASpain. For VASloc the correlation was good. However, there was no difference between treatments, indicating low sensibility. No correlation was observed between pressure sensitive walkway and HCPI. We concluded that the questionnaire has construct and criterion validity, reliability and can be applied in dogs with osteoarthritis in Portuguese-speaking countries.(AU)
