Many parturients have poor self-care ability, strong dependence on others, and lack mother-infant related nursing skills and health care knowledge. Due to their lack of pregnancy experience, many primiparas lack the relevant skills and knowledge, which can affect maternal and infant health and maternal quality of life. The study aimed to investigate the effects of the PRECEDE-PROCEDE model on self-care ability and quality of life among primipara during puerperium. This quasi-clinical study selected eligible primaparas from those who gave birth at a Grade A hospital in Hengyang, China between April and July 2019. Eighty puerperium primiparas were divided into a control group receiving standard care and an intervention group following the PRECEDE-PROCEDE model. Comparison of self-care ability and quality of life scores was conducted between the two groups pre-intervention, at 3 weeks, and at 6 weeks postpartum. Statistical analysis using SPSS 18.0 included mean and standard deviation for measurement data, and frequency and constituent ratio for counting data. Tests such as t-test, Chi-squared test, rank-sum test, and repeated measure analysis of variance were applied. The control group's self-care ability scores were (150.8 ± 9.9), (150.9 ± 9.3), and (152.0 ± 10.2) before intervention, at 3 weeks postpartum, and at 6 weeks postpartum, respectively. For the intervention group, the corresponding scores were (151.1 ± 15.1), (157.8 ± 8.5), and (162.4 ± 7.2). Quality of life scores for the control group were (54.7 ± 8.6), (54.8 ± 7.7), and (55.1 ± 7.7) before intervention, at 3 weeks postpartum, and at 6 weeks postpartum, respectively. At the same time points, while the intervention group saw increases from (55.6 ± 7.6) to (59.2 ± 5.9) and (61.0 ± 5.3). There were statistically significant differences in the time effect and inter-group effect of the total score of self-care ability during puerperium, total score of quality of life, and the score of each dimension between the two groups (P < 0.05), and we also found an interaction effect between grouping and time factors (P < 0.05). After intervention, the incidence of common puerperium health problems except neonatal constipation and diarrhea in the intervention group was lower than that in the control group (P < 0.05). PRECEDE-PROCEDE model may improve self-care ability, reduce the occurrence of common health problems, and improve the quality of life of primiparas during puerperium.
