Psychometric evaluation of a 6‐item Chinese version of the Hamilton Depression Rating Scale: Mokken scaling and item analysis

Psychometric evaluation of a 6‐item Chinese version of the Hamilton Depression Rating Scale:... INTRODUCTIONThe 17‐item Hamilton Depression Rating Scale (HAM‐D17) is one of the most widely used measure of depression (Bech, ; Bech, Paykel, Sireling, & Yiend, ; Østergaard, Bech, & Miskowiak, ). As the HAM‐D17 is a multidimensional scale, the sum scores of the HAM‐D17 are problematic for measuring depression (Bech, ; Bech et al., ; Østergaard et al., ). Recent studies have shown that the 6‐item melancholia subscale (HAM‐D6) of the HAM‐D17 has superior psychometric properties compared with the HAM‐D17 (Bech, ; Østergaard et al., , ). The HAM‐D6 consists of depressed mood, decreased work and interests, general somatic symptoms, psychic anxiety, guilt feelings, and psychomotor retardation (Bech et al., ). The HAM‐D6 is a unidimensional scale and may be an efficient outcome measure of antidepressant trials (Bech, ; Bech et al., ; Østergaard et al., ).It is unclear whether the HAM‐D6 has adequate psychometric properties in the Chinese populations (Li, Xu, & Gao, ).
