昼夜节律紊乱与双相情感障碍（BD）在情绪发作和缓解期。据报道，缓解患者晚上的昼夜节律相位偏好，而其节律的幅度和稳定性从未使用问卷进行过评估。本研究的主要目的是验证法国版的昼夜节律类型量表（CTI），而其次要目的是比较BD缓解患者和健康对照组的节律稳定性和振幅以及相位偏好。为此，我们使用了CTI和早晨综合量表（CSM）来评估相位偏好（“早晨”或“晚上”类型）。首先，我们在这里报告的140例BD缓解患者和156名健康对照样本的11项昼夜节律类型清单的法国版本的验证。主成分分析揭示了双因素结构（FR：与节律稳定性对应的灵活性/刚性量表; LV：与节律振幅对应的倦怠/活力量表），解释了对照组和双相组中52%和47%的方差。FR和LV的Cronbach α分别为0.75和0.73。重测信度为0.74 FR和0.86 LV（3周）和0.62 FR和0.72 LV（6个月）。LV和FR评分与早晨综合量表评分相关（p
Circadian rhythm disturbances have been associated with bipolar disorder (BD) during both the mood episodes and the periods of remission. Circadian phase preferences for the evening have been reported for remitted patients, whereas the amplitude and stability of their rhythms have never been assessed using questionnaires. The primary aim of our study was the validation of a French version of the Circadian Type Inventory (CTI), whereas its secondary aim was the comparison between remitted patients with BD and healthy controls for rhythm stability and amplitude and for phase preference. For this purpose, we used the CTI and the Composite Scale of Morningness (CSM) that assesses phase preference ("morning" or "evening" type). First, we report here on the validation of the French version of the 11-item Circadian Type Inventory in a sample of 140 remitted patients with BD and 156 healthy controls. Principal components analysis revealed a two-factor structure (FR: flexibility/rigidity scale corresponding to rhythm stability; LV: languid/vigorous scale corresponding to rhythm amplitude) explaining 52% of the variance in the control group and 47% in the bipolar group. Cronbach's alpha was 0.75 for FR and 0.73 for LV. The test-retest reliability was 0.74 for FR and 0.86 for LV (3 wks) and 0.62 for FR and 0.72 for LV (6 mos). LV and FR scores correlated with the Composite Scale of Morningness score (p
