Consumer and provider responses to a computerized version of the Illness Management and Recovery Program.

Objective: To explore mental health consumer and provider responses to a computerized version of the Illness Management and Recovery (IMR) program.

Method: Semistructured interviews were conducted to gather data from 6 providers and 12 consumers who participated in a computerized prototype of the IMR program. An inductive-consensus-based approach was used to analyze the interview responses.

Psychometric comparison of computerized and standard administration of the neurocognitive assessment instruments selected by the CATIE and MATRICS consortia among patients with schizophrenia.

Unlabelled: Neurocognitive assessment is an essential component for clinical trials of candidate "cognitive-enhancing" treatments for schizophrenia. However, manual administration of large, paper-based, neurocognitive batteries is often inefficient, error-prone, and inconsistent across multiple sites. Existing computerized testing systems are also limited both in the assessment instruments available and in the range of impairments that can be accommodated with the subject sitting alone at a single display.

Alpha EEG predicts visual reaction time.

Studies have suggested that consciousness is encoded discretely in time and synchronously in space of the brain. The present study was to model the alpha EEG as a brain clock to carry out the functions and to test whether the quality and rate of the oscillation could predict behavioral timing. Results showed that the alpha peak frequency was correlated with the conflict reaction time, and the selectivity was associated with the simple reaction time.

Evaluation of a novel EEG preamplifier.

The authors performed initial clinical testing of a novel EEG transduction module (ETM), designed to record EEG signals from electrodes with high and unbalanced contact impedances. Twenty patients underwent two consecutive EEG studies. In the first, "experimental" study, electrodes were applied to an unprepared scalp, and the ETM performed initial signal transduction and pre-amplification.
