This study examined differential responses among partners who participated in a RCT designed to compare two social cognitive theory interventions, one designed for patients only (P-only) and one for patients and their intimate partners (P + P). The interventions were delivered following the patient receiving an initial ICD implant. Partner health outcomes were examined longitudinally from baseline at hospital discharge to 3, 6, and 12 months. Outcomes included 6 measures: partner physical and mental health status (Short-Form-36 PCS and MCS), depression (Patient Health Questionnaire-9), anxiety (State-Trait Anxiety Inventory), caregiver burden (Oberst Caregiver Burden Scale), and self-efficacy in ICD management (Sudden Cardiac Arrest Self-efficacy scale). Growth mixture and mixed effect modeling were used to identify and compare trajectories of 6 health outcomes within the P-only and P + P arms of the study. Partners (n = 301) were on average 62 years old, female (74.1%) and Caucasian (83.4%), with few co-morbidities (mean Charlson Co-morbidity index, 0.72 ± 1.1). Two types of profiles were observed for P-only and P + P, one profile where patterns of health outcomes were generally better across 12 months and one with outcome patterns that were generally worse across time. For PCS, no significant partner differences were observed between P-only or P + P in either the better (p = 0.067) or the worse (p = 0.129) profile types. Compared to P-only, partners in the worse profile improved significantly over 12 months in MCS (p = 0.006), caregiver burden P + P (p = 0.004) and self-efficacy P + P (p = 0.041). Compared to P-only, P + P partners in the low anxiety profile improved significantly (p = 0.001) at 3 months. Partners with more psychosocial distress at hospital discharge benefited most from the P + P intervention. Among partners with generally low levels of anxiety, those in the P + P intervention compared to P-only showed greater improvement in anxiety over 12 months.

这项研究检查了参与旨在比较两种社会认知理论干预措施的随机对照试验的合作伙伴之间的不同反应，一种是专为患者设计的（P-only），另一种是为患者及其亲密伴侣设计的（P+P）。干预措施是在患者接受初始 ICD 植入后进行的。伙伴从出院时的基线到 3、6 和 12 个月，对健康结果进行了纵向检查。结果包括 6 项指标：伴侣身心健康状况（Short-Form-36 PCS 和 MCS）、抑郁症（患者健康问卷 9）、焦虑症（状态-特质焦虑量表）、照顾者负担（Oberst Caregiver Burden Scale）和ICD 管理中的自我效能感（心脏骤停自我效能感量表）。生长混合物和混合效应模型用于识别和比较研究的 P-only 和 P + P 组中 6 种健康结果的轨迹。合作伙伴 (n = 301) 平均为 62 岁，女性 (74.1%) 和高加索人 (83.4%)，几乎没有合并症（平均 Charlson 合并症指数，0.72 ± 1.1）。对于 P-only 和 P + P，观察到两种类型的配置文件，一种情况下，健康结果模式在 12 个月内通常更好，另一种情况下结果模式通常随着时间的推移而更差。对于 PCS，在 P-only 或 P + P 之间没有观察到显着的合作伙伴差异，无论哪个更好（p  = 0.067) 或更差的 ( p  = 0.129) 配置文件类型。与 P-only 相比，12 个月内处于较差状态的合作伙伴在 MCS（p  = 0.006）、照顾者负担 P + P（p  = 0.004）和自我效能 P + P（p  = 0.041）方面显着改善。与仅 P 相比，低焦虑状态的 P + P 合作伙伴在 3 个月时显着改善 ( p  = 0.001)。出院时有更多社会心理困扰的合作伙伴从 P + P 干预中受益最多。在焦虑水平普遍较低的合作伙伴中，与仅 P-P 相比，P + P 干预的合作伙伴在 12 个月内的焦虑改善更大。
