Validation of computer-administered clinical rating scale: Hamilton Depression Rating Scale assessment with Interactive Voice Response technology--Japanese version.
The aim of this study was to examine the reliability and validity of the Interactive Voice Response (IVR) program to rate the 17-item Hamilton Rating Scale for Depression (HAM-D) score in Japanese depressive patients. ⋯ Our results suggest that the Japanese IVR HAM-D program is reliable and valid to assess 17-item HAM-D total score in Japanese depressive patients. However, the current program tends to overestimate depression severity, and the score of each item did not always show high agreement with clinician's rating, which warrants further improvement in the program.

Repeated transcranial magnetic stimulation on dorsolateral prefrontal cortex improves performance in emotional memory retrieval as a function of level of anxiety and stimulus valence.
Anxiety behavior showed a consistent attentional bias toward negative and aversive memories, induced by a right frontal cortical superiority, based on an unbalance effect between the two hemispheres. The aim of the present study was to explore the role of the left dorsolateral prefrontal cortex (DLPFC) in the memory retrieval process of positive versus negative emotional stimulus, as a function of anxiety level. ⋯ Left DLPFC activation favors the memory retrieval of positive emotional information and might limit the unbalance effect induced by right hemispheric superiority in high levels of anxiety.
