Abstract
Indonesian mothers of children with Autistic Spectrum Disorder (ASD) often need support to enhance their resilience, but no scale is available to assess mothers' resilience in daily activities. Therefore, the aim of this study was to develop a new scale to measure resilience in daily occupation of mothers of children with ASD. Methods: Aspects of resilience in daily activities were generated from literature and developed into 37 questions following a dual-panel methodology. The draft scale was sent to 200 mothers of children with ASD, of which 148 were returned (valid response rate: 74 %). Reliability was investigated using classical test theory. A further 30 draft scales were filled out by another 30 mothers twice, 10-15 days apart. Test-retest reliability was evaluated by Spearman's r. Results: The analysis resulted in the Resilience in Daily Activities Scale (RDAS) consisting of 27 questions, divided into 5 factors. We obtained 0.90 Cronbach'α for the scale, and for the values for each subscale were, achieving life balance 0.88, thinking about child's future 0.86, families' supports 0.82, managing daily activities 0.73, understanding children's condition 0.64. Test-retest reliability was 0.68. Conclusion: RDAS showed appropriate psychometric properties indicating its usability to evaluate resilience in daily activities in Indonesian mothers of children with ASD. In consideration of the sample characteristics, further study is needed, particularly to include mothers from rural regions.
