Scientific Name: Homo sapiens Species: Human


The General Health Questionnaire (GHQ) Test Battery is a self-evaluation that measures the current mental state of the individual. The GHQ is one of three Standard Measures (SM) test batteries conducted at Russia’s Institute for Biomedical Problems’ (IBMP) Nazemnyy eksperimental’nyy kompleks (NEK) facility. The purpose of the standard measures project is to populate a repository with data that enables high-level monitoring of countermeasure effectiveness and meaningful interpretation of health and performance outcomes. The NEK standard measures will support future, hypothesis-driven research that enables planetary missions by providing an optimized minimal set of measures captured from subjects. These measures will be available to other studies under data sharing agreements as well as undergo analysis to understand risk posture.

The General Health Questionnaire (GHQ) evaluates the mental state of crewmembers via two self-evaluations, GHQ-12 and GHQ-28. The GHQ evaluations will be used for current and future bed rest studies. The GHQ-12 provides an overall total score of mental health, while the GHQ-28 provides scores on four subscales of somatic symptoms: anxiety, insomnia, social dysfunction and severe depression, in addition to an overall total score of mental health. The advantage of having these four subscales makes the GHQ-28 a useful measure for bed rest studies. Each item on the GHQ is rated on a 4-point scale (0 to 3) indicating ‘less than usual’, ‘no more than usual’, 'rather more than usual’, ‘and much more than usual’.
