title: Testing a cognitive model of menopausal hot flushes and night sweats.
abstract: OBJECTIVE
  Hot flushes and night sweats (HFNS) are commonly experienced by women during the menopause transition and are particularly problematic for approximately 25% having negative impact on their quality of life. We previously developed a cognitive model of HFNS, which outlines potential predictors of HFNS. This study aims to test the model by investigating the relationships between personality characteristics, perceived stress, mood, HFNS beliefs and subjective and physiological measures of menopausal HFNS.
  
  
  METHODS
  140 women (menopause transition or postmenopausal) who were experiencing at least 10 HFNS per week for at least a month, completed assessment interviews, including questionnaires assessing optimism, somatic amplification, perceived stress, depressed mood, anxiety, HFNS beliefs and HFNS frequency, problem-rating and 24-hour sternal skin conductance monitoring. Structural equation models (SEM) were used to investigate the optimum predictive model for HFNS Frequency and HFNS Problem-Rating.
  
  
  RESULTS
  On average 63 HFNS per week and moderately problematic HFNS were reported. The physiological measure of HFNS frequency was not associated with socio-demographic variables, personality or mood. The final SEM explained 53.2% of the variance in problem rating. Stress, anxiety and somatic amplification predicted HFNS problem rating but only via their impact on HFNS beliefs; HFNS frequency, smoking and alcohol intake also predicted HFNS problem rating.
  
  
  CONCLUSIONS
  Findings support the influence of psychological factors on experience of HFNS at the level of symptom perception and cognitive appraisal of HFNS.
