According to a report on the BBC News website, MPs are to be surveyed about their mental health with questions about depression, their sense of self-worth and their drinking habits.
The report says:
Former health minister Dr Dan Poulter is conducting the study alongside King’s College London.
The Tory MP said he had seen colleagues clearly struggling with very low mood and behaving erratically under stress.
Researchers say it could establish if mental health issues are more prevalent among MPs than the general population.
The study, based on a standard psychiatric questionnaire, will ask MPs whether they feel they can face up to their problems, overcome difficulties or think of themselves as worthless.
