■这项研究的目的是研究六年来习惯性乐观情绪的变化,并分析乐观情绪的变化与其他生活质量相关变量的变化之间的关系。
■对德国成年普通人群(N=4,965)的随机选择的社区样本进行了两次调查,时间间隔为6.04年。
■在6年的过程中,LOT-R总量表的平均得分提高(效应大小d=0.11).就测试-重测相关性而言,总样本的时间稳定性为r=0.61。在这种时间稳定性中只有轻微的性别差异,然而,年龄最大的≥70岁(r=0.50)的稳定性低于其他年龄组的稳定性。横断面相关性显示了乐观情绪与生活质量之间的明确关系,生活满意度,社会支持,另一方面,低水平的焦虑和身体不适。乐观情绪的变化与其他变量的变化之间的相应纵向相关性不太明显,但在同一个方向。
■该研究证实了LOT-R在纵向研究中的适用性。在70岁及以上参与者的样本中,在临床实践和流行病学研究中需要考虑乐观评估的有限稳定性.
UNASSIGNED: The aims of this study were to examine changes in habitual
optimism over a six-year period and to analyze the relationship between changes in
optimism and changes in other quality of life-related variables.
UNASSIGNED: A randomly selected community sample of the German adult general population (N = 4,965) was surveyed twice, with a time interval of 6.04 years.
UNASSIGNED: During the course of the 6 years, the mean score of the LOT-R total scale improved (effect size d = 0.11). The temporal stability in terms of the test-retest correlation was r = 0.61 for the total sample. There were only marginal gender differences in this temporal stability, however, the stability in the oldest age group ≥70 years (r = 0.50) was lower than the stability of the other age groups. The cross-sectional correlations showed clear relationships between
optimism on the one hand and quality of life, life satisfaction, social support, and low levels of anxiety and physical complaints on the other. The corresponding longitudinal correlations between changes in
optimism and changes in the other variables were less pronounced, but in the same direction.
UNASSIGNED: The study confirmed the applicability of the LOT-R in longitudinal studies. In samples with participants of 70 years and above, the limited stability in the
optimism assessments needs to be considered in clinical practice and epidemiologic research.
