The effect of yoga on neuroticism in an Indian population varies with socio-demographic factors.

Neuroticism, or negative affectivity, can influence a person's approach to life. This study examined levels of neuroticism in 249 patients with illnesses known to be related to the mental state. All of them were given a six-day intensive yoga program. Patients showed a decrease in neuroticism measured by the PGI Health Questionnaire. The reduction was maximum for (a) those with ages between 36 and 51 years, (b) females, (c) patients with at least 17 years of education, and (d) those who were self-employed. The results show the importance of socio-demographic factors in neuroticism levels and in programs intended to reduce neuroticism. Hence, yoga is a useful intervention to reduce traits of neuroticism, with variations in the degree of change based on social factors.
