asthma control on the basis of perceived stress, locus of control, and self-efficacy in patients with adult asthma

objective: this study aimed to investigate the prediction of asthma control on the basis of perceived stress, locus of control, and self-efficacy in adult patients with asthma.  methods: this was a descriptive-correlative and cross-sectional study.the solecty of this study is all asthmatic patients in tehran. our sample consisted of 100 participants who were selected by purposeful sampling method. a total of 100 patients with asthma were selected among outpatients of masih daneshvari hospital. participants included 52 women and 48 men. their mean (±sd) age was 36.12 (±9.82) years. sociodemographic data were collected and perceived stress scale (pss), multidimensional health locus of control (mhlc), asthma self-efficacy scale (ases), and asthma control test (act) were applied. data were analyzed by pearson correlation and multiple regression analysis. statistical analysis was performed using the spss ver. 16.0.  results: the results indicated that there were negative significant relationships between perceived stress, dimension of external control (chance) and asthma control, but positive significant relationships between self-efficacy and asthma control. in regression analysis, the perceived stress was the predictor of asthma control.  conclusion: in this study, our findings suggest that perceived stress has an important role in the development and maintenance of asthma symptoms. in addition, self-efficacy and a tendency to externally attribute the locus of control (chance) are significantly associated with asthma control.
