title: Mediators of the relationship between social support and positive health practices in middle adolescents.
abstract: BACKGROUND
  This correlational study developed and tested theory to better understand positive health practices (PHPs) in middle adolescents. It tested theoretic relationships postulated between PHPs and (a) social support (SS), (b) optimism, and (c) loneliness, and between SS and the variables of optimism and loneliness. Optimism and loneliness were tested as possible mediators in the relationship between SS and PHPs.
  
  
  METHODS
  A convenience sample of 204 middle adolescents was obtained. Participants completed a demographic sheet and four instruments.
  
  
  RESULTS
  There were statistically significant positive relationships between SS (r=.44) and optimism (r=.54) with PHPs. There was a statistically significant negative relationship between loneliness (r=-.39) and PHPs. There was a statistically significant positive relationship between optimism (r=.63) and SS. There was a statistically significant negative relationship between loneliness (r=-.76) and SS. Optimism was found to partially mediate the relationship between SS and PHP; loneliness did not.
  
  
  CONCLUSIONS
  Findings contribute to a more comprehensive knowledge base regarding health practices in middle adolescents.
