McNemar's Test

1.0K
McNemar's Test is a nonparametric statistical test used to determine if there is a significant difference in proportions between two related groups when the outcome is binary (e.g., yes/no, success/failure). It is beneficial when we have paired data, such as pre-test/post-test designs, where the same subjects are measured under two different conditions. The test is named after the statistician Quinn McNemar, who introduced it in 1947. It is commonly used in situations where subjects are...

Three-Phase Short Circuit—Unloaded Synchronous Machine

918
Conducting a three-phase short circuit test on an unloaded synchronous machine helps understand its impact on the system. The AC fault current's oscillogram, with the DC offset removed, reveals that the waveform amplitude decreases from an initially high value to a steady-state level for one phase of the machine.
This behavior occurs due to the magnetic flux produced by the short-circuit armature currents. Initially, these currents follow high-reluctance paths but eventually shift to...

This summary is machine-generated.

The Norwegian MATRICS Consensus Cognitive Battery (MCCB) effectively identifies neurocognitive impairments in psychotic disorders. These cognitive deficits correlate with reduced educational, occupational, and social functioning in patients.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Clinical Psychology

Background:

  • Neurocognitive impairment is a key characteristic of psychotic disorders.
  • The MATRICS Consensus Cognitive Battery (MCCB) is a standard tool for assessing neurocognition.
  • The Norwegian translation of the MCCB requires validation in adult clinical populations.

Purpose of the Study:

  • To evaluate the Norwegian MCCB in adult patients with psychotic disorders.
  • To compare neurocognitive performance between patients and healthy controls.
  • To investigate the association between neurocognition and functional outcomes in patients.

Main Methods:

  • Administered the Norwegian MCCB to 131 patients with psychotic disorders and 137 healthy controls.
  • Compared neurocognitive scores between patient and control groups.
  • Analyzed correlations between MCCB domains and measures of educational, occupational, and social functioning.

Main Results:

  • The Norwegian MCCB detected significant neurocognitive impairments across all domains in patients compared to controls.
  • Patients exhibited widespread cognitive deficits relative to their healthy counterparts.
  • Neurocognitive performance was significantly associated with educational, occupational, and social functioning.

Conclusions:

  • The Norwegian MCCB is a sensitive measure for assessing neurocognitive deficits in psychotic disorders.
  • Cognitive impairments identified by the MCCB are linked to functional impairments in this population.
  • Findings support the use of the Norwegian MCCB for clinical assessment and research in psychosis.
