The aim of this study was to describe the development of the paediatric daily occupation scale (PDOS) that was validated with Taiwanese children aged from birth to 72 months. Item-scale correlation coefficient was also used to select items. The psychometric properties of PDOS were examined based on the results of 957 children who participated in the study. The Chinese child development inventory (CCDI) was used as a standard to examine the concurrent validity of PDOS on two different samples. The PDOS, completed by parents, contains 340 items with good internal consistency (Cronbach's alpha = 0.99), test-retest reliability (r = 0.99) and concurrent validity (r = 0.88 between PDOS and CCDI). The sensitivity of PDOS (83%) in detecting children with developmental problems was much higher than CCDI (33%). Because the PDOS is developed and examined on children from greater Taipei area, when using the PDOS with children from different socio-cultural environments, the results need to be interpreted cautiously. Further research of the PDOS to justify its use as a screening tool for early detecting of children with developmental problems is suggested.
本研究旨在描述儿科日常活动量表（PDOS）的编制过程，该量表已在台湾地区0至72个月的儿童中进行了效度验证。同时，还运用项目-量表相关系数来筛选条目。基于957名参与研究儿童的结果，对PDOS的心理测量学特性进行了检验。采用中国儿童发展量表（CCDI）作为标准，在两个不同样本上检验PDOS的同时效度。由家长完成的PDOS包含340个条目，具有良好的内部一致性（克朗巴哈系数α = 0.99）、重测信度（r = 0.99）和同时效度（PDOS与CCDI之间的r = 0.88）。PDOS检测发育问题儿童的敏感度（83%）远高于CCDI（33%）。由于PDOS是针对大台北地区儿童编制和检验的，因此在将其用于不同社会文化环境的儿童时，对结果的解读需谨慎。建议对PDOS进行进一步研究，以证明其作为早期检测发育问题儿童筛查工具的合理性。
