title: Consistency of self-reported sexual behavior and condom use among current sex partners.
abstract: OBJECTIVE
  The objective of this study was to determine concordance in sex partner reports of frequency of vaginal and oral intercourse and condom use.
  
  
  METHODS
  Self-reported behaviors among 112 women treated for urinary tract infection (UTI), sore throats, or receiving birth control at a student health service were compared with that of their current sex partner.
  
  
  RESULTS
  Correlation was excellent for frequencies of vaginal intercourse (r = 0.88), cunnilingus (r = 0.72), fellatio (r = 0.76), and condom use (r = 0.86), but women with UTI compared with women without UTI reported greater frequency of sexual activity than their sex partner. This effect overwhelmed the modest increases in correlation associated with duration of relationship and marital status.
  
  
  CONCLUSIONS
  Women with genitourinary symptoms may over-recall frequency of sexual behavior compared to women without these symptoms. Knowing the extent of this recall bias will assist in the interpretation of data and appropriate correction of parameters when included in prediction models.
