Effects of a goal attainment program via line OA on self-care behaviors and hematocrit in pregnant adolescents with anemia: A quasi-experimental study.

Objective: To evaluate the effect of a goal attainment program using the LINE OA application, Teen Mom Care (GAP-LINE OA: TMC), on self-care behaviors and hematocrit levels among pregnant adolescents with anemia.

Methods: A quasi-experimental, two-group pretest-posttest design was used. The study included 54 pregnant adolescents receiving antenatal care at six hospitals in southern Thailand from April to June 2024. Participants were divided into a control group (n = 27), receiving standard care, and an experimental group (n = 27), receiving standard care combined with GAP-LINE OA: TMC. Data were collected twice: at baseline (before 28 weeks of gestation with hematocrit < 33%) and at four weeks post-intervention. Instruments included GAP-LINE OA: TMC, a demographic questionnaire, and a self-care behavior questionnaire for pregnant adolescents with anemia. Data were analyzed using descriptive statistics, chi-square, t-test, Wilcoxon signed-rank test, and Mann-Whitney U test.

Results: In the experimental group, self-care behavior scores and hematocrit levels significantly improved after the intervention compared with baseline (P < 0.001). Inter-group analysis showed significantly greater increases in self-care behavior scores and hematocrit levels in the experimental group compared with the control group (P = 0.044).

Conclusion: The GAP-LINE OA: TMC program effectively enhances self-care behaviors and improves hematocrit levels in pregnant adolescents with anemia. The GAP-LINE OA: TMC program can enhance antenatal care by providing targeted support, goal-setting interventions, and improved communication for pregnant adolescents with anemia via the LINE OA platform.
