Résumé
Objective To study the role of coping styles in the relationship between coping resources and psychosomatic health in patients with asthma. Methods 184 adult patients with asthma were investigated with General Serf-Efficacy Scale (GSES), Internality, Powerful Others, and Chance Scale (IPC), Social Support Rat-ing Scale (SSRS), Defensive Style Questionnaire (DSQ), Trait Coping Style Questionnaire (TCSQ) and Short Form 36 Health Survey Questionnaire (SF-36). Results Significant correlation between self-efficacy (r=0.356),locus of control(Ir=0.208, Pr=0.341, Cr=-0.349) ,subjective(r=0.201) and objective(r=0.189)social support, immature and middle ( r = - 0. 257 ) defensive styles and coping styles ( PCr = 0.231, NCr =-0.505 ) with Mental Component Summary (MCS) was found (all P <0.05), but Physical Component Summary (PCS) was only related to self-efficacy( r=0. 175) ,chance(r=0.150),immature(r=-0.256) and middle de-fensive Styles and negtive coping styles (all P < 0.05). PCS (t = - 5.189) and MCS (t = - 6. 758) could be predic-ted effectively by negative coping style (all P<0.01). Moreover, self-efficacy, powerful others and the use of so-cial support could had an effect on the health of patients through negative coping style. Conclusion Negative coping style could not only have a direct effect on the health of asthma patients but also be a mediator between self-efficacy, locus of control, social support and the health of patients.
