To evaluate the effectiveness of Developmental Surveillance and Promotion Manual -Family-mediated Preschool Parenting Program (DSPM-FMPP) on Emotional Quotient (EQ) of early childhood subjects. MATERIALS AND METHODS:This study is an experimental study using pre-post comparison. Data were collected from early childhood subjects between 3-6 years old at child development centers and schools in Phayamengrai District, Chiangrai Province. The samples consist of 30 children who participated in DSPM-FMPP from 1 February to 31 May 2020. Relevant data were gathered from medical records. RESULT:The results reveal that after participating in the program, the mean EQ scores of the subjects were significantly higher than the mean EQ scores before participating in the program (42.40 ± 3.18 VS 50.20 ± 3.44, p < 0.001). The EQ scores were found to have increased by approximately 7.83 points (p < 0.001). The levels of EQ achieved were normal or better for all 30 samples after having participated in the program (p < 0.001). CONCLUSION:The DSPM-FMPP might increase the EQ of children in early childhood. Parents should promote development and reinforce the positive discipline of early childhood regularly and continuously.
