Mean duration and frequency of pauses within speech, pauses between speakers, and vocal activity were measured in 28 endogenous depressive during a psychiatric interview. A factor analysis on these variables revealed two factors accounting for 50% and 24% of the variance, respectively. Factor 1 could be interpreted as a pause factor. The mean durations of both types of pauses had high negative loadings, whereas the frequency of vocal activity, simultaneous speech, and pauses, and the mean duration of vocal activity had high positive loadings on this factor. The degree of retardation (a measure for slowed mental and physical activity) also was related to this factor (r = -0.67, p less than 0.001), whereas the relation between the severity of depression and this factor could only be established under certain conditions. The second factor was interpreted as a fragmentation of speech factor. The frequency of switching pauses (between speakers) and of vocal activity had high positive loadings, and the mean duration of vocal activity had a high negative loading. No clear relationships could be demonstrated between the degree of agitation (a measure for mental and physical overactivity) and speech and pause variables.
在一次精神科访谈中，对28名内源性抑郁症患者言语中的停顿平均时长和频率、说话者之间的停顿以及发声活动进行了测量。对这些变量进行因子分析后发现了两个因子，分别解释了50%和24%的方差。因子1可解释为停顿因子。两种停顿类型的平均时长在该因子上有较高的负负荷，而发声活动、同步言语和停顿的频率以及发声活动的平均时长在该因子上有较高的正负荷。迟缓程度（衡量精神和身体活动减慢的指标）也与该因子相关（r = -0.67，p < 0.001），而抑郁严重程度与该因子之间的关系仅在某些条件下才能确立。第二个因子被解释为言语碎片化因子。切换停顿（说话者之间）的频率和发声活动的频率在该因子上有较高的正负荷，而发声活动的平均时长在该因子上有较高的负负荷。未发现激越程度（衡量精神和身体活动过度的指标）与言语和停顿变量之间有明确的关系。
