Development and validation of a questionnaire assessing household work limitations (HOWL-Q) in women with rheumatoid arthritis.
IntroductionRheumatoid arthritis (RA) has female preponderance and interferes with the ability to perform job roles. Household work has 2 dimensions, paid and unpaid. There is not a validated instrument that assesses the impact of RA on limitations to perform household work. We report the development and validation of a questionnaire that assesses such limitations, the HOWL-Q.MethodsThe study was performed in 3 steps. Step-1 consisted on HOWL-Q conceptual model construction (literature review and semi-structured interviews to 20 RA outpatients and 20 controls, household workers, who integrated sample (S)-1). Step-2 consisted of instructions selection (by 25 outpatients integrating S-2), items generation and reduction (theory and key informant suggestions, modified natural semantic network technique, and pilot testing in 200 household workers outpatients conforming S-3), items scoring, and questionnaire feasibility (in S-3). Step-3 consisted of construct (exploratory factor analysis) and criterion validity (Spearman correlations), and HOWL-Q reliability (McDonald's Omega and test-retest), in 230 household work outpatients integrating S-4.ResultsPatients conforming the 4 samples were representative of typical RA outpatients. The initial conceptual model included 8 dimensions and 76 tasks/activities. The final version included 41 items distributed in 5 dimensions, was found feasible and resulted in 62.46% of the variance explained: McDonald's Omega = 0.959, intraclass-correlation-coefficient = 0.921 (95% CI = 0.851-0.957). Moderate-to-high correlations were found between the HOLW-Q, the HAQ, the Quick-DASH and the Lawton-Brody index. HOWL-Q score ranged from 0 to 10, with increasing scores translate into increase limitations.ConclusionThe HOWL-Q showed adequate psychometric properties to evaluate household work limitations in women with RA
ENGIU: Encuentro Nacional de Grupos de Investigación de UNIMINUTO.
El desarrollo del prototipo para el sistema de detección de Mina Antipersona
(MAP), inicia desde el semillero ADSSOF perteneciente al programa de Administración en Seguridad y Salud en el trabajo de la UNIMINUTO, se realiza a partir de un
detector de metales que emite una señal audible, que el usuario puede interpretar
como aviso de presencia de un objeto metálico, en este caso una MAP. La señal
audible se interpreta como un dato, como ese dato no es perceptible a 5 metros de
distancia, se implementa el transmisor de Frecuencia Modulada FM por la facilidad
de modulación y la escogencia de frecuencia de transmisión de acuerdo con las
normas y resolución del Ministerio de Comunicaciones; de manera que esta sea la
plataforma base para enviar los datos obtenidos a una frecuencia establecida. La
idea es que el ser humano no explore zonas peligrosas y buscar la forma de crear
un sistema que permita eliminar ese riesgo, por otro lado, buscar la facilidad de uso
de elementos ya disponibles en el mercado
