The Barthel Index: Validity and Reliability

Using the Barthel Index (BI), you can assess how well a patient is doing with his or her daily tasks in regards to personal care and physical mobility. The instrument was created for chronic patients and long-term hospital patients suffering from paralytic disorders, with the goal of assessing their performance before and after therapy was initiated. The Barthel Index has been utilized for a variety of purposes, including forecasting the length of time required for rehabilitation and the amount of nursing assistance required.


The Barthel Index is formatted as a 10-item or 15-item response with a four-point scale, depending on the version used. It will take you 5 minutes to finish the test.


The Barthel ADL Index: Important Guidelines 

  • To begin, the index should only be used to keep track of what a patient actually performs, rather than what a patient might be able to do in the future.
  • The primary goal is to achieve a degree of independence from any form of assistance, physical or verbal, no matter how minor and for whatever reason.
  • Because of the need for supervision, the patient is unable to function independently.
  • The best available evidence should be used to determine a patient's ability to perform. The patient, friends/family members, and nurses are the most typical sources of information, but direct observation and common sense are also significant. Direct testing, on the other hand, is not required.
  • Typically, the patient's performance over the preceding 24-48 hours is considered, but longer periods may be relevant in some cases as well.
  • To be classified as a middle category, the patient must provide more than 50% of the effort.
  • It is permissible to use aids sufficient.

Reliability and Validity


The dependability scores for the two principal versions of the Barthel Index – the 10-item and the 15-item – were both extremely high. Using the 15-item version, Granger (1979) calculated test-retest reliability and internal reliability of 0.89 and 0.95, respectively, with even better numbers reported by Shinar (1980) and (1987). According to Shah, the alpha internal consistency coefficient for the 10-item scale ranges from 0.87 to 0.92. The Barthel Index, which is correlated with a motor ability index, was assigned a value ranging from.73 to.77. The Barthel Index was unanimously agreed to be a reliable instrument for predicting mortality that was also simple to use. The Barthel index score can be calculated using an online Barthel index calculator, but a medical decision support system can also be used for the same.
