Development and validation of a new bariatric-specific health-related quality of life instrument ′′bariatric and obesity-specific survey (BOSS)′′

Abstract

BOSS thus appears to be a valid and reliable multidimensional instrument that provides a clinically useful and relevant measure to assess HRQOL in patients undergoing bariatric surgery.

Validation of a new measure of quality of life in obesity trials: Impact of Weight on Quality of Life‐Lite Clinical Trials Version

“…Several established measures are available to assess the impact of obesity on patient functioning and HRQOL, including the original 31‐item IWQOL‐Lite, developed in 2001 . The original IWQOL‐Lite is still widely used to evaluate the impact of obesity and the potential benefits of weight‐loss interventions, and the evidence base established since its development in 2001 provides valuable knowledge for use in clinical research and clinical practice.…”

“…Whereas HRQOL may be broadly assessed using generic measures such as the SF‐36 Health Survey (SF‐36) and the Sickness Impact Profile, disease‐specific measures evaluate these impacts within the context of a specific health condition. Several obesity‐specific measures of HRQOL have been developed, including the Impact of Weight on Quality of Life‐Lite (IWQOL‐Lite) questionnaire, which is widely used in evaluations of diverse weight‐loss interventions …”

“…Whereas HRQOL may be broadly assessed using generic measures such as the SF-36 Health Survey (SF-36) 4 and the Sickness Impact Profile, 5 diseasespecific measures evaluate these impacts within the context of a specific health condition. Several obesity-specific measures of HRQOL have been developed, [6][7][8][9][10] including the Impact of Weight on Quality of Life-Lite (IWQOL-Lite) questionnaire, 11 which is widely used in evaluations of diverse weight-loss interventions. [12][13][14][15][16][17] While the IWQOL-Lite has demonstrated strong psychometric properties, 11,18,19 the content was initially based on the input of individuals undergoing intensive residential treatment for obesity and related comorbid conditions.…”

Recommendations on the most suitable quality‐of‐life measurement instruments for bariatric and body contouring surgery: a systematic review

“…The measurement properties of the bariatric and obesity-specific survey were evaluated in one study. Moderate evidence was found for good internal consistency and reliability (32). There was moderate evidence for indeterminate content validity and structural validity (32).…”

“…Moderate evidence was found for good internal consistency and reliability (32). There was moderate evidence for indeterminate content validity and structural validity (32). The evidence of hypotheses testing remains unknown because of poor methodological quality of the study (32).…”
