To evaluate the reliability and validity of the English and Spanish versions of the Strengths and Weaknesses of ADHD-symptom and Normal-behavior (SWAN) rating scale.
Parents of preschoolers completed both a SWAN and the well-established Strengths and Difficulties Questionnaire (SDQ) on two separate occasions over a span of 3 months; instruments were in the primary language of the family (English or Spanish).
Psychometric properties for the English and Spanish versions of the SWAN were adequate, with high internal consistency and moderate test-retest reliability. Skewness and kurtosis statistics for the SWAN were within the range expected for a normally distributed population. The SWAN also demonstrated adequate convergent and discriminant validity in correlations with the various subscales of the SDQ.
Psychometric properties of both the English and Spanish versions of the SWAN indicate that it is a reliable and valid instrument for measuring child attention and hyperactivity. The stability of ratings over time in this preschool sample was moderate, which may reflect the relative instability of these characteristics in preschool children.
评估多动症症状和正常行为(SWAN)评定量表的英文和西班牙文版本的信度和效度。
家长在 3 个月的时间内分两次完成 SWAN 和经过充分验证的长处和困难问卷(SDQ),工具采用家庭的主要语言(英语或西班牙语)。
SWAN 的英文和西班牙文版本的心理测量特性良好,具有较高的内部一致性和中等的重测信度。SWAN 的偏度和峰度统计数据在正态分布人群的预期范围内。SWAN 与 SDQ 的各个分量表之间的相关性也表明具有足够的聚合和区分效度。
SWAN 的英文和西班牙文版本的心理测量特性表明,它是一种可靠和有效的测量儿童注意力和多动性的工具。在这个学龄前儿童样本中,评分随时间的稳定性为中等,这可能反映了这些特征在学龄前儿童中相对不稳定。
