Sense of coherence, mental well-being and perceived preoperative hospital and surgery related stress in surgical patients with malignant, benign, and no neoplasms

This prospective, cross-sectional, observational study examined associations between sense of coherence (SOC), mental well-being, and perceived preoperative hospital and surgery related stress of surgical patients with malignant, benign, and no neoplasms. The objective was to assess a putative association between SOC and preoperative stress, and to test for a statistical mediation by mental well-being. The sample consisted of 4918 patients from diverse surgical fields, of which 945 had malignant neoplasms, 333 benign neoplasms, and 3640 no neoplasms. For each subsample, we conducted simple mediation analyses to test an indirect effect of SOC on preoperative stress mediated by mental well-being. The models were adjusted for age, gender, and essential medical factors. Patient groups did not differ significantly regarding degrees of SOC and mental well-being (SOC, M [SD]: 12.31 [2.59], 12.02 [2.62], 12.18 [2.57]; mental well-being M [SD]: 59.26 [24.05], 56.89 [22.67], 57.31 [22.87], in patients with malignant, benign, and without neoplasms, respectively). Patients without neoplasms reported significantly lower stress (4.19 [2.86], M [SD]) than those with benign (5.02 [3.03], M [SD]) and malignant neoplasms (4.99 [2.93], M [SD]). In all three mediation models, SOC had significant direct effects on stress, with higher SOC being associated with lower stress (- 0.3170 [0.0407], - 0.3484 [0.0752], - 0.2919 [0.0206]; c' [SE], p
