HOD Test Apps
OrthoHOD Pro App (for health professionals)
The Ortho-HOD Pro test is a combined test that encompasses 2 parts.
The first part is a test developed by Drs. Abram Hoffer and Humphrey Osmond that gauges perception and depression. Previously known as the HOD (Hoffer-Osmond Diagnostic) test, it is a series of 145 true/false questions designed to measure errors of perception. The virtue of the HOD test rests in its ability to give an accurate snap-shot of a patient’s perceptual world in a time saving and convenient manner.
Results from the HOD test can either be used to determine the necessity for Orthomolecular Niacin (Vitamin B3) and Vitamin C supplementation (with a score of 30 or higher), or as an objective indicator for when cannabis and other cognitive impairing substances would be unsuitable for use as either a prescription or for recreational purposes.
The second part of the Ortho-HOD Pro test is a series of 39 true/false questions that give insight into areas of brain chemistry that may be deficient and can be corrected with targeted nutrition (also listed). These results also provide clues to physicians regarding lab workup requirements where necessary. The following video explains the App in greater detail.
The OrthoHOD Pro App is available in the iTunes App store in both iPhone and iPad formats as well as on Google Play for Android formats.
The following is a list of the references and research that went into creating the HOD test. Although it is not exhaustive, it will be updated regularly as further research comes to light.
OrthoHOD (for Harm Reduction)
Substance use and abuse is a growing problem in mental health. It has been given ample lip-service by health and government authorities, yet few tools have been made available to the public that will adequately address it in a constructive fashion.
The OrthoHOD App is a scaled down version for public use that will give the user an idea of whether or not cognition altering substances should be avoided. The following video explains this version of the App:
