Partial remission in major depression: A two-phase, 12-month prospective study

The movements were examined in accordance with the Comprehensive Body Examination. The study objects were 99 persons: 17 pain syndrome patients (PSP group), 27 psychotic patients (PP group), 4 non-psychotic patients (NPP group), and a comparison group consisting of 51 students and staff members (SS group). On the basis of factor analysis three subscales were made: 1) Resistance to Passive Movements (RPM), with nine items, 2) Assistance to Passive Movements (APM), with six items, and 3) Motor Disturbances (MD), with three items. The internal consistency of the subscales was high (Chronbach's alpha, 0.81-0.96), and the intercorrelation low to moderate. The RPM subscale distinguished significantly between the SS group and both patient groups; the APM and MD subscales distinguished between the SS group and the PP group. The MD subscale also distinguished between patients taking drugs and those who did not, but there was no difference between patients without medication and the SS group.
