The Highs scale has been developed to evaluate hypomanic symptoms in the first postpartum week. However, it has not been elucidated whether this scale is also applicable to pregnant women. To address this issue, we confirmed the factor structure, reliability, and validity of the Japanese version of the Highs scale for pregnant and postpartum women. 418 women provided effective responses to both the Highs scale and the Edinburgh Postnatal Depression Scale (EPDS) during early pregnancy (before week 25), late pregnancy (around week 36), at 5 days and at 1 month after delivery. Subjects were randomly divided into two groups, and exploratory and confirmatory factor analyses were performed for each group. Cronbach's alpha was calculated and the correlation of the Highs scale with EPDS was analyzed. The correlation between the subscales was analyzed at four time points, and the correlation of subscales between the four time points was confirmed. This scale was found to have the two-factor structure with elation and agitation subscales. The two subscales had reasonable internal consistency at all time points (Cronbach's alpha range: Factor 1, 0.696-0.758; Factor 2, 0.553-0.694). The overall scale had reasonable internal consistency at all time points (Cronbach's alpha range: 0.672-0.738). Based on the correlation analysis of the two subscales and EPDS, discriminative and convergent validity were indicated at all time points, confirming the construct validity of the Highs scale. Subscale scores showed a significant correlation with EPDS at all time points ( = 0.388, 0.384, 0.498, and 0.442, < 0.01). The Japanese version of the Highs scale is reliable and valid, and can be applied for evaluating the hypomanic symptoms during pregnancy and postpartum period.
Highs量表已被开发用于评估产后第一周的轻躁狂症状。然而，该量表是否也适用于孕妇尚未阐明。为了解决这个问题，我们确认了适用于孕妇和产后妇女的日语版Highs量表的因子结构、信度和效度。418名女性在孕早期（第25周之前）、孕晚期（约第36周）、产后5天和产后1个月时对Highs量表和爱丁堡产后抑郁量表（EPDS）都给出了有效回答。受试者被随机分为两组，对每组进行探索性和验证性因子分析。计算Cronbach's α系数，并分析Highs量表与EPDS的相关性。在四个时间点分析各子量表之间的相关性，并确认四个时间点之间子量表的相关性。发现该量表具有包含兴高采烈和激越子量表的双因子结构。这两个子量表在所有时间点都具有合理的内部一致性（Cronbach's α系数范围：因子1为0.696 - 0.758；因子2为0.553 - 0.694）。整个量表在所有时间点都具有合理的内部一致性（Cronbach's α系数范围：0.672 - 0.738）。基于两个子量表与EPDS的相关性分析，在所有时间点都显示出区分效度和聚合效度，证实了Highs量表的结构效度。子量表得分在所有时间点与EPDS均显示出显著相关性（r = 0.388、0.384、0.498和0.442，P < 0.01）。日语版Highs量表可靠且有效，可用于评估孕期和产后的轻躁狂症状。
