Validating a measure of temperament

▪ Correlations between the subscales The correlations among the five temperament subscales were shown in Table 2.We previously validated the Chinese 110-item TEMPS-A (full-version) in a clinically-well Chinese population [4], and applied it in different clinical populations to investigate the impact of affective temperaments on cognitive deficits [11].Subsequently a Chinese short version, translated from the 39-item English TEMPS-A [15] was developed by Yuan, .[16]. For instance, item 19 (“I’m the kind of person who doubts everything”), item 81(“I am a very skeptical person”) and item 66 (“I complain a lot”) that loaded on the depressive temperament may not be applicable to the Chinese culture [4].Most of the temperament subscales were associated with each other.The strongest positive correlation was observed between the cyclothymic and anxious temperaments (r=0.54).The males scored significantly higher on the hyperthymic and irritable subscales than did the females.Finally, the frequency of the dominant temperaments defined as two standard deviations above the mean) was the highest for the depressive temperament (6.0%), followed by the cyclothymic, anxious (4.2%), irritable (2.8%), and hyperthymic (0%) temperaments.The reconstructed 63-item Chinese TEMPS-A was administered to 879 clinically-well Chinese Han population aged 16-60 years without a history of mental disorders.Results: A principal component analysis with Varimax rotation found that 45 out of the 63 items loaded onto five factors, namely cyclothymic, hyperthymic, anxious, irritable, and depressive factors.An increasing body of evidence suggests interwoven relations between the affective temperaments measured by the TEMPS-A and affective disorders.For instance, hyperthymic temperament was overrepresented in individuals with bipolar I disorder, whereas cyclothymic temperament was overrepresented in individuals with bipolar II disorder [7].
