VALIDITY AND RELIABILITY OF SHIFT WORK DISORDER QUESTIONNAIRE AMONG INDONESIAN FEMALE NURSES
Nurses on shift work experience several symptoms such as excessive sleep, insomnia, feeling tired and fatigue. This situation could be inimical to health, and lead to the conditions known as shift work disorder (SWD). A tool is needed to measure shift work disorder among shift work nurses. It can be used to understand the ailment, and support strategies to prevent it. The aim of this study was to adapt SWD questionnaire for use in Bahasa. The study was a cross-sectional study among 201 female nurses who worked on shift duties at public hospital from March to April 2020. The questionnaires were self-administered via an online platform. SWD questionnaire was measured using three questions from previous study. It was used to measure sleep disorder related to work schedule. Permission to use this questionnaire was granted by original author. The process of translation and adaptation SWD questionnaire based on WHO studies. Cronbach alpha was used to measure internal consistency reliability. Exploratory factor analysis (EFA) using principal axis factor to examine construct validity. Confirmatory factor analysis (CFA) was used to assess the structural model fit of SWD. The cronbach alpha for SWD questionnaire was 0.834, which indicated adequate reliability. All of the items in SWD questionnaire had factor loading greater than 0.32, and the CR and AVE of SWD questionnaire were 0.951 and 0.751, which indicated good convergent validity. This study validates the psychometric properties of SWD questionnaire among Indonesia Female Nurses, including translation, validity, and reliability.
