The feasibility of a brief evaluation of mental state at the time of the offense

If psychological evaluations of criminal defendants could be performed in the community on an outpatient basis rather than in a distant state hospital on an inpatient basis, substantial savings could result and defendants' rights to speedy trial, bail, and the least restrictive alternative would more likely be respected. The authors thus developed a protocol, the mental state at the time of the offense screening evaluation (MSE), designed to enable outpatient evaluatiors to “screen out,” in the course of a brief interview, those defendants whose alleged criminal conduct clearly was not caused by “significant mental abnormality.” They tested the validity of the MSE by having pairs of mental health professionals use the MSE to evaluate 36 criminal defendants. The professionals' conclusions were then compared with the conclusions of state hospital professionals who performed a comprehensive evaluation of each defendant. They were also compared to court adjudications of the defendant's criminal charges. They found that the MSE screened out a large proportion of defendants (sufficient to suggest an improvement in cost-efficiency) without prejudice to those defendants who might have a valid legal defense.
