Assess Your Patient's Perception of Quality of Life After Illness or Injury with this Self-Report


A 243-item self-report questionnaire, the RNBI is appropriate for use following a major illness or injury. The RNBI can provide diagnostic insights, assess treatment outcomes, and track the rate of improvement based on the patient’s self-perceptions of daily problems.

Features and benefits

  • Measures perception of the important dimensions of daily life following a catastrophic event.
  • Psychometrically captures patients’ cognitive, emotional, and physical complaints and also assesses quality of life issues.
  • Two dimensions underlie the structure of the RNBI. 1) The first component evaluates the individual’s intrapersonal problems by assessing the individual’s own perception of his or her health. 2) The second, interpersonal, evaluates an individual’s perception of his or her social support system, as well as vocational status, financial resources, spirituality, and recreational outlets.
  • Scale scores are combined to create four Premorbid and four Postmorbid Composite scale scores, which provide global information about the individual’s perceived cognitive, emotional, and physical functioning as well as his or her overall quality of life.
  • Two validity scales assess abnormal response styles; two assess impression management.
  • The 17 RNBI critical items provide additional interpretive information within various clinical areas of interest.
  • Allows judgments based on normative data for either the general population or a clinical population.
  • Captures premorbid functions in a comprehensive manner, facilitating a direct comparison between premorbid and posttrauma functioning.
