The study was conducted to assess the effectiveness of slow paced breathing on pain perception during first stage of labor among 60 primigravida mothers which shows that i n experimental group 11 (36.7%) belongs to age group of 21-24 years, 14 (46.7%) were graduated, 16 (53.3%) were homemakers, 11 (36.7%) have monthly income more than 30,001, majority 19 (63.3%) have joint family, 28 (93.3%) were Hindu, 20 (66.7%) were residing in rural, majority 28 (96.7%) primigravida mothers had regular checkups. In comparison of post test score in experimental and control group the calculated “t” value was found to be statistically very highly significant (7.366) at P less than 0.001 level of significance which shows the significant difference between post-test scores regarding pain among primigravida mothers in experimental group and control group. Study findings revealed that there was no significant association of post-test scores with their socio-demographic variables. Therefore, selected socio-demographic variables had no impact on pain perception during first stage of labor among primigravida mothers.
