Construction and Empirical Study of Indirect Intervention Model for Protective Medical Lung Cancer Patients Based on Family System Theory

Anhui Medical University160 enrolled

Overview

To clarify the irrational cognition of family caregivers of lung cancer patients at various perioperative stages under the background of protective medical treatment, construct an indirect intervention model for lung cancer patients, and evaluate its clinical efficacy. To develop popularizable cognitive intervention tools and formulate practical cognitive intervention strategies, so as to relieve perioperative stress responses among lung cancer patients and their family caregivers. To provide reliable evidence and research directions for carrying out comprehensive and systematic interventions on perioperative stress responses in lung cancer patients and their family caregivers in clinical practice in the future.

Outcomes

Primary Outcomes

Decisional Conflict（DCS）

Patient decisional conflict level is assessed using the validated 16-item Decisional Conflict Scale (DCS). Each item adopts a 5-point Likert rating with partial reverse scoring (1=strongly agree, 2=agree, 3=uncertain, 4=disagree, 5=strongly disagree). The mean raw score (1-5) of all items is linearly converted to a standardized total score of 0-100 via formula: (mean score-1)×25. Higher total scores indicate greater decisional conflict.
