Psychometric qualities of measurement tools used to determine workplace horizontal violence: A rapid review.

Unlabelled: RATIONALE AIMS AND OBJECTIVES: Horizontal violence has been defined as aggressive or hostile behaviour directed at an individual or between colleagues from the same working group. Measuring the prevalence of horizontal violence requires valid measures. To date, there has not been a review of the psychometric properties of available measurement tools for horizontal violence.

Method: A rapid review of the MEDLINE and BUSINESS EBSCO databases was conducted to identify studies testing the validity of any measure of horizontal violence in any workplace setting. Title and abstract and full-text screening, data extraction and quality appraisal were completed by two researchers working independently. The COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) was used to determine the methodological quality of studies, including details of the psychometric properties of included papers.

Results: Fourteen papers reporting 17 studies were included in the review. Seven measures of horizontal violence (Civility Norms Questionnaire Brief; Negative Acts Questionnaire-Revised; Inventory of Violence and Psychological Harassment; Leyman Inventory Psychological Terror Mobbing of Single Cases of Harassment in Employees Relations; Shortened Negative Acts Questionnaire-Revised; Uncivil Workplace Behaviour Questionnaire) were identified. Most included studies were methodologically robust. Six measures had strong psychometric properties except for the Mobbing of Single Cases of Harassment in Employees Relations (MSCH) where key information about psychometric properties was not reported.

Conclusions: We identified six measures of horizontal violence that had good psychometric properties. The Negative Acts Questionnaire-Revised has been most extensively tested in different settings but is not necessarily a more precise measure than others.
