Study Notes

Physical Therapy Measurement and Analysis Summary

  • Reliability measures the consistency and stability of data recorded by a tester across multiple trials or by multiple testers.
  • Variance of scores coefficient of 1.00 indicates the best reliability, while a coefficient closer to 0 indicates less reliability.
  • Different types of reliability measures include test-retest reliability, intra-rater reliability, and inter-rater reliability.
  • Validity ensures that measurement tools provide accurate and unbiased information. It includes face validity, criterion-related validity, and predictive validity.
  • Blinding methods such as single blinding, double blinding, and triple blinding help in removing bias from the study.
  • Sampling bias, publication bias, snowball sampling, and cluster random sampling are important concepts in research methodology.
  • Intention-to-treat (ITT) analysis considers all randomized participants in the analysis, whether they drop out or not, while per-protocol analysis only analyzes data from those who strictly adhered to the study protocol.
  • Different study designs include parametric and non-parametric designs, single-subject designs, case reports, n of 1 trials, and experimental study designs.
  • Sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, number needed to diagnose, and diagnostic odds ratio are important concepts in diagnostic testing.
  • Intraclass correlation coefficient (ICC) measures reliability on continuous data outcomes, while Kappa coefficient measures reliability on dichotomous outcomes.
  • Systematic review involves looking back and reporting findings using specific inclusion/exclusion criteria, while meta-analysis involves statistical analysis of data reported by researchers.
  • Sensitivity and specificity are key measures in diagnostic testing, with sensitivity representing the true positive rate and specificity representing the true negative rate.
