OLBI validity and reliability: what the research shows and what it does not

Research supports the OLBI as a two-factor measure with acceptable reliability, validated across several occupations and countries. It does not support using it as a diagnostic test: its accuracy against a physician-based measure was modest in one study. [3][5][9]

Where did the OLBI come from?

It was developed by Demerouti and colleagues in the German-speaking research tradition and later translated. One publisher dates the original German development to 1999 and the Greek-sample work to 2003. [5] Halbesleben and Demerouti published the first validation of the English translation in Work & Stress in 2005, motivated by concerns about the Maslach inventory. [7] Secondary sources report that it correlated highly with the Maslach subscales and less strongly with job satisfaction and depression. [5][7]

How reliable are the scores?

One publisher summarising published studies reports Cronbach's alpha, a measure of how consistently the items agree, of .74 to .87 for exhaustion and .70 to .83 for disengagement. [5] Values around .70 and above are conventionally considered acceptable for research, though lower than one would want for individual decisions. Reliability figures vary with sample and language.

Does a two-factor structure fit?

Studies using confirmatory factor analysis have supported a two-factor structure, reported across several countries. [5]

A study of 528 South African construction workers compared burnout and engagement measures, including the OLBI. It found that cynicism and dedication behaved as opposite ends of one attitude dimension, while exhaustion and vigour were highly correlated but not opposite ends of one continuum. [8]

The practical lesson is that the OLBI's exhaustion and disengagement scales are supported as two separate scales, and that the field is still debating how burnout and engagement relate.

How well does it identify burnout?

The OLBI does not identify burnout well enough to be used as a diagnostic test. In a study of 123 Belgian patients, it was compared with a tool completed by a physician. [9]

Two measures show how well a test sorts people. Sensitivity is how often it flags people who do have the condition, and specificity is how often it correctly clears people who do not. The OLBI had a sensitivity of 0.70 and a specificity of about 0.60 to 0.67, and the authors suggested using both tools together. [9]

Burnout is handled differently in different countries, from a formal diagnosis in Sweden to cut-off scores in the Netherlands, so there is no single standard to validate a questionnaire against. [3] The WHO classifies it as an occupational phenomenon, not a medical condition. [2]

What does validity evidence not establish?

That the questionnaire measures burnout as the WHO defines it in full, that a score predicts illness or absence in you, or that an online version behaves like the research one. Research on a questionnaire does not validate every adaptation or every use. It also does not tell you what is causing the score.

What should I check before trusting an online burnout score?

Ask these questions before you trust an online burnout score:

  • Does it say which version it is, and cite the research?
  • Does it explain how it calculates the score, including reversed items?
  • Does it say what the number means, and does it avoid diagnosing?
  • Does it tell you what to do next, including when to see a doctor?
  • Does it state how it treats your data?
