It was administered twice, with a 1-week interval, to 120 patients with advanced cancer.Together with the HAD scale, the patients also completed the Spielberger State-Anxiety Scale (STAI-S).test anxiety in school children could be for many reasons.The scale was translated with the “forward-backward” procedure to Greek.Internal consistency coefficients (tau non-equivalent) were 0.74 and 0.86 respectively.

The Chinese MDAS consisted of two factors: anticipatory dental anxiety (ADA) and treatment dental anxiety (TDA).

Validity as performed using known-group analysis showed good results.

Both anxiety and depression subscales discriminated well between subgroups of patients differing in disease severity as defined by ECOG performance status.

Factor analyses identified a two-factor solution corresponding to the original two subscales of the HAD, which were found to be correlated.

The Greek version of the HAD had Cronbach’s alphas for the anxiety and depression scales of 0.887 and 0.703, respectively.
