title: The Parent-Teen Sexual Risk Communication Scale (PTSRC-III): instrument development and psychometrics.
abstract: BACKGROUND
  Adolescents are a group at high risk for sexually transmitted infections (STIs), including the human immunodeficiency virus (HIV). Several parenting processes, including parental monitoring, support, role modeling, and sexual communication, have been shown to be significant influences of adolescents' sexual attitudes, beliefs, and behaviors. Parent-child sexual risk communication, in particular, has been associated significantly with adolescents' attitudes, beliefs, and behaviors related to risk of and prevention of STIs and HIV.
  
  
  OBJECTIVE
  The aim of this study was to report on the development of the Parent-Teen Sexual Risk Communication Scale (PTSRC-III), an eight-item self-report instrument for measuring the amount of communication about sexual risk and sexual risk reduction occurring between parents and their adolescent children, as reported by the adolescent.
  
  
  METHODS
  Psychometrics of the PTSRC-III and the stability of the psychometric properties across two samples of late adolescents, college freshmen (N=95) and female licensed drivers aged 19 to 21 years (N=234), are reported.
  
  
  RESULTS
  Internal reliability of the scale was excellent (alpha of >.93 and >.88 for sexual risk communication with mothers and fathers, respectively); test-retest reliability was acceptable (r=.88 and .79 over 2 months for PTSRC with mothers and fathers, respectively). Concurrent validity, predictive validity, and stability of psychometrics were also demonstrated. Factor analysis demonstrated a two-factor structure.
  
  
  CONCLUSIONS
  The PTSRC-III provides a valid and reliable measure for assessing female adolescents' perceptions of parent-teen sexual risk communication, particularly with their mothers. Psychometrics were shown to be stable across the two samples. Implications for use and future development are discussed.
