摘要目的:基于主客体互倚模型（APIM）探讨前列腺癌患者与其主要照顾者相依关系对积极感受的影响。方法:该研究属于前瞻性、单中心试验。选取江南大学附属医院2021年5月至2023年5月收治的133例前列腺癌患者及其主要照顾者为研究对象，前列腺癌患者均为男性，年龄49～90（70.52±12.65）岁；主要照顾者男42名，女91名，年龄22～79（62.56±10.45）岁。参考相依关系量表（MS）、积极感受量表（PAC）调查患者与主要照顾者的相依关系、积极感受，采用 t检验统计分析前列腺癌患者与主要照顾者相依关系评分、积极感受评分差异；采用Pearson分析前列腺癌患者与主要照顾者相依关系、积极感受的相关性；采用线性混合模型APIM分析前列腺癌患者与主要照顾者相依关系对积极感受的影响。 结果:前列腺癌患者的相依关系中爱和感情维度评分、总分均高于主要照顾者［（4.45±0.77）分比（2.62±0.55）分、（15.75±2.88）分比（13.60±2.25）分］，积极感受中自我肯定、生活展望评分以及总分均低于主要照顾者［（12.34±2.11）分比（13.28±2.59）分、（13.46±2.53）分比（15.30±2.95）分、（25.80±4.25）分比（28.58±3.43）分］，差异均有统计学意义（ t=22.30、6.78、3.25、5.46、5.87，均 P<0.05）；患者相依关系与主要照顾者相依关系、积极感受呈正相关（ r=0.887、0.718，均 P<0.001），患者积极感受与主要照顾者相依关系、积极感受呈正相关（ r=0.590、0.527，均 P<0.001）；主体效应上，患者及其主要照顾者的相依关系可影响自身的积极感受（ β=0.474、0.485，均 P<0.05）；客体效应上，患者及其主要照顾者的相依关系可影响对方的积极感受（ β=0.356、0.265、0.344、0.315，均 P<0.05）。 结论:前列腺癌患者与其主要照顾者之间的相依关系评分与自身和对方的积极感受评分呈正相关，且经APIM模型验证其相依关系可正向影响二者积极感受。

abstractsObjective:To explore the influence of the dependence between patients with prostate cancer and their primary caregivers on positive feelings based on the actor-partner interdependence model (APIM).Methods:This study was a prospective and single-center trial. One hundred and thirty-three patients with prostate cancer treated at Hospital Affiliated to Jiangnan University from May 2021 to May 2023 and their main caregivers were selected as the research objects; the patients were 49-90 (70.52±12.65) years old; among the caregivers, there were 42 males and 91 females who were 22-79 (62.56±10.45) years old. The dependence and positive feelings of the patients and their main caregivers were investigated by the Dependence Scale (MS) and Positive Feeling Scale (PAC). t test was used to statistically analyze the differences of dependency score and positive feeling score between the patients and their main caregivers. Pearson analysis was used to analyze the dependence and positive feelings of the patients and their main caregivers. The linear mixed model APIM was used to analyze the influence of dependence between the prostate cancer patients and their main caregivers on positive feelings. Results:The scores of love and affection dimensions and total score in the dependent relationship of the prostate cancer patients were higher than those of the primary caregivers [(4.45±0.77) vs. (2.62±0.55) and (15.75±2.88) vs. (13.60±2.25)]; the scores of self-affirmation and life outlook and total score in positive feelings of the patients were lower than those of their primary caregivers [(12.34±2.11) vs. (13.28±2.59), (13.46±2.53) vs. (15.30±2.95), and (25.80±4.25) vs. (28.58±3.43)]; there were statistical differences ( t=22.30, 6.78, 3.25, 5.46 and 5.87; all P<0.05). The patients' dependence was positively correlated with the caregivers' dependence and positive feelings ( r=0.887 and 0.718; both P<0.001); the patients' positive feelings was positively correlated with the caregivers' dependence and positive feelings ( r=0.590 and 0.527; both P<0.001). On the subjective effect, the dependence between the patients and their caregivers could affect their positive feelings ( β=0.474 and 0.485; both P<0.05). On the object effect, the dependence between the patients and their caregivers could affect each other's positive feelings ( β=0.356, 0.265, 0.344, and 0.315; all P<0.05). Conclusion:The score of dependence between patients with prostate cancer and their main caregivers is positively correlated with the score of their own and each other's positive feelings, and it is verified by the APIM that their dependence can positively affect their positive feelings.
