Short report: sleep quality and associations with health locus of control and coping styles in young people with ankylosing spondylitis.

The poor sleep of young people with ankylosing spondylitis (AS) has not attracted enough attention of clinicians and experts. This study aimed to evaluate the sleep quality and associations with health locus of control (HLC) and coping styles in young people with AS. A total of 133 patients completed the measures of demographics, disease characteristics, HLC, coping styles, and Pittsburgh sleep quality index (PSQI). The patients were worse than general population in PSQI global score and multiple domains. Among patients, the poor sleep was positively related to chance HLC (CHLC) and resignation. Resignation completely mediated the association between CHLC and sleep. There were severe sleep problems in young people with AS, and strategies to change the resignation coping style should be implemented.
