Cognitive behavioural correlates to bereavement-related mental health problems such a Prolonged Grief Disorder (PGD) and Posttraumatic Stress Disorder (PTSD) are of theoretical and clinical importance.
Individuals bereaved at least six months (N = 647) completed measures of loss-related cognitions and behaviours (i.e., loss-related memory characteristics, negative appraisals, coping strategies, grief resilience, and perceived social disconnection) and measures of PGD and PTSD symptoms. Individuals were assigned to one of four groups depending on probable clinical diagnoses (No-PGD/PTSD, PTSD, PGD, PGD+PTSD).
Results indicated that higher loss-related memory characteristics and lower grief resilience increased the likelihood of a clinical problem. The PGD and PGD+PTSD groups reported significantly higher loss-related memory characteristics and appraisals compared to the PTSD group. Social disconnection increased the likelihood of comorbid PGD+PTSD in comparison to any other group.
Results indicate cognitive differences between loss-related cognitions, memory characteristics and coping strategies between PGD and PTSD, and points to distinct cognitive correlates to psychopathology following loss.
与丧亲相关的心理健康问题（如延长哀伤障碍（PGD）和创伤后应激障碍（PTSD））的认知行为相关性具有理论和临床意义。
至少丧亲六个月的个体（N=647）完成了与丧失相关的认知和行为（即与丧失相关的记忆特征、负面评价、应对策略、悲伤适应能力和感知的社会脱节）以及 PGD 和 PTSD 症状的测量。根据可能的临床诊断（无 PGD/PTSD、PTSD、PGD、PGD+PTSD）将个体分配到四个组之一。
结果表明，较高的与丧失相关的记忆特征和较低的悲伤适应能力增加了临床问题的可能性。PGD 和 PGD+PTSD 组报告的与丧失相关的记忆特征和评价明显高于 PTSD 组。与任何其他组相比，社会脱节增加了共病 PGD+PTSD 的可能性。
结果表明，PGD 和 PTSD 之间与丧失相关的认知、记忆特征和应对策略存在认知差异，并指出丧失后精神病理学的特定认知相关性。
