Abstract:
Objective To explore the chain mediating effects of perceived stress and depression between Type D personality and quality of life in patients with Crohn's disease.Methods A total of 270 patients who visited our hospital for Crohn's disease from September 2022 to July 2023 were enrolled in this study with convenience sampling method.Perceived stress scale(PSS),patient health questionnaire 9(PHQ-9),Type D personality scale(DS-14),22-item inflammatory bowel disease quality-of-life questionnaire(IBDQOL-22)and the Crohn's disease activity index(CDAI)were employed in the survey.Pearson correlation or Spearman correlation analysis was used to explore the correlation between Type D personality,perceived stress,depression and quality of life in patients with Crohn's disease.Structural equation modelling was conducted using MPLUS 8.0 software,and confidence intervals were calculated using Bootstrap method for chain mediation analysis.Results A total of 269 patients with Crohn's disease had completed the survey.Total scores for IBDQOL,PHQ-9 and PSS were(82.7±13.7),3.0(1.0-7.0)and(24.4±7.5),respectively and the scores for the dimensions of negative emotion and social inhibition of DS-14 were(10.3±5.9)and(11.6±5.5),respectively.A total of 117(43.5%)patients were identified with Type D personality among 269 patients with Crohn's disease.The structural equation model revealed that Type D personality did not directly or significantly affect the quality of life(effect value=0.034,95%CI:-0.130 to 0.206).However indirectly,perceived stress and depression significantly mediated the relationship between Type D personality and quality of life,with a total indirect effect size of-0.307(95%CI:-0.423 to-0.207),a chain mediation effect size of-0.048(95%CI:-0.079 to-0.016),accounting for 15.6%of the total indirect effect.Conclusions The quality of life in patients with Crohn's disease is moderate.Perceived stress and depression both play a significant role between Type D personality and quality of life of the patients.Attention should be paid to the patients with Type D personality,hence the quality of life of patients could be improved through the intervention of stress perception and depression.
