Objective To explore the potential profile characteristics and influencing factors of binary psychological capital in patients with enterostomy and their spouses.

Methods A total of 273 patients with enterostomy were selected as the research subjects by using the convenience sampling method. Questionnaire surveys were conducted among patients and their spouses using general information questionnaires, stoma function adaptation scales, psychological capital scales, Kessler Psychological Status Assessment Scales and perceived social support scales, etc. The latent subtypes of binary psychological capital were identified through latent profile analysis, and the multiple logistic regression analysis was used to explore the influencing factors of different subtypes.

Results The potential profile analysis showed that the dual psychological capital of enterostomy patients and their spouses could be divided into three potential categories: the dual low psychological capital - high stress group (n = 23, 8.42%), dual medium-high psychological capital - low optimism group (n = 61, 22.34%) and dual high psychological capital - good adaptation group (n = 189, 69.23%). The stoma type of enterostomy patients, postoperative complications, monthly family income, score of the Perceived Social Support Scale and age of the spouse were the main influencing factors of the binary psychological capital potential profile (P ＜ 0.05 to P ＜ 0.01).

Conclusions There is significant heterogeneity in the dual psychological capital levels of enterostomy patients and their spouses, and the psychological states of the two have the characteristic of mutual influence. Medical staff should start from the perspective of binary interaction and formulate individualized intervention strategies in combination with different psychological capital characteristics to enhance the psychological adaptability of patients and their spouses.
