text: Yo, check it out, we got survey instruments in the house,
  Measuring health-related quality of life, no doubt.
  Researchers got options, from short to long,
  One to hundreds of items, where they belong.
  
  We took a sample, 35 chronically ill adults,
  They took the Short-form General Health Survey, no insults.
  Twenty items, measuring quality of life,
  Reliable and valid, it's the real-life vibe.
  
  One specific item stood tall and strong,
  A single measure of health-related quality, you can't go wrong.
  It correlated positively, with the overall score,
  Proving its worth, we couldn't ask for more.
  
  These results got our back, supporting the claim,
  When resources or sample size ain't the same,
  This single-item measure, it's the way to go,
  When the multiple-item ones just can't show.
