目的 探讨基于时机理论的阶段干预方案在早产儿父亲中的应用效果，为改善其心理健康提供现实依据。方法 2024年1-3月，以便利抽样法选取青岛某三级甲等医院新生儿重症监护室收治的53例早产儿的父亲为对照组，接受常规健康教育；2024年4-6月同法选择55例早产儿的父亲为试验组，接受基于时机理论的阶段干预方案，两组均干预至出院后1个月。分别在早产儿入院当天（T0）、出院当天（T1）、出院后1周末（T2）、出院后1个月末（T3），比较两组的抑郁发生率、焦虑水平；出院当天比较两组的出院准备度；出院后1周末、出院后1个月末比较两组育儿参与度。结果 T1~T3期，试验组抑郁发生率、焦虑得分均低于对照组（均P＜0.05）；T1期试验组出院准备度高于对照组（P＜0.001）；T2~T3期，试验组育儿参与度亦高于对照组，差异均有统计学意义（均P＜0.001）。结论 基于时机理论的阶段干预方案能有效降低早产儿父亲的抑郁发生率和焦虑水平，显著提高其出院准备度和育儿参与度。

Objective To explore the application effects of a phased intervention program based on the timing theory for fathers of premature infants，and to provide a realistic basis for improving their mental health.Methods From January to March 2024，53 fathers of premature infants admitted to the neonatal intensive care unit (ICU) of a tertiary A hospital in Qingdao were selected as the control group by the convenience sampling method and received routine health education.From April to June 2024，55 fathers of premature infants were selected as the experimental group by the same method and received a staged intervention program based on the timing theory.Both groups were intervened until one month after discharge.The incidence of depression and the level of anxiety in the two groups were compared respectively on the day of admission (T0)，the day of discharge (T1)，the week after discharge (T2)，and the month after discharge (T3) of premature infants.On the day of discharge，the discharge readiness of the two groups was compared.The parenting participation of the two groups was compared at the end of one week and the end of one month after discharge.Results In stages T1 to T3，the incidence of depression and the score of anxiety in the experimental group were both lower than those in the control group (all P＜0.05).The discharge readiness of the experimental group in stage T1 was higher than that of the control group (P＜0.001).In stages T2 to T3，the parenting participation of the experimental group was also higher than that of the control group，and the differences were statistically significant (all P＜0.001).Conclusions The phased intervention program based on the timing theory can effectively reduce the depression incidence and anxiety levels of fathers of premature infants and significantly improve their discharge readiness and parenting participation.
