Type D Personality Parents of Children With Leukemia Tend to Experience Anxiety

The aims were to access anxiety and type D personality (TDP) in parents of children with leukemia, and to determine the mediating effect of social support and coping style on the relationship between TDP and anxiety. A cross-sectional study was conducted among 231 parents of children with leukemia and 261 parents of children with acute diseases in hospitals. Parents completed questionnaires on anxiety, TDP, social support, coping styles, children's clinical characteristics, and demographic characteristics. Parents of children with leukemia showed higher prevalence of anxiety (64.5% vs 40.2%, P < 0.01) and TDP (44.2% vs 24.1%, P < 0.01) compared with controls. TDP (odds ratio [OR] = 4.34, P < 0.01), lower social support (OR = 1.92, P = 0.02), and less positive coping (OR = 1.87, P = 0.02) were independently associated with anxiety. Parents with TDP showed lower social support and less positive coping, but more negative coping compared with those without. Moreover, multiple mediation analyses revealed that the significant effect of TDP on anxiety was partially mediated by social support and positive coping. In conclusion, anxiety and TDP were highly prevalent in parents of children with leukemia. The predictive factors could be used to identify those parents who are at high risk of anxiety and may also be targets for prevention and intervention.
