Psychometric Validation Moves Closer to Market Access Discussions in Canada
A questionnaire can perform well in one country and still create problems when introduced elsewhere. That reality is drawing greater attention to psychometric and linguistic validations performed in Canada. At the moment, many stakeholders are looking for instruments that will function equally efficiently when applied to representatives of various language groups.
The problem does not concern only translation issues since a direct language conversion might result in preserved wording and changed meanings. Questions appearing straightforward in one population may have completely different implications when evaluated by others. Therefore, organizations conducting patient-reported outcomes surveys, educational assessments and other types of testing need to pay particular attention to the matter to make sure that the collected information is interpretable.
When it comes to validation in Canada, there is no simple approach involving two main languages. In practice, the task includes examination of cultural background, reading level and response options used in the questionnaire. The objective is to evaluate an instrument rather than translate it.
Today, organizations working with various health and social organizations are paying attention to the matter since measurement validity has become crucial for research quality. Consequently, the problem becomes obvious when sponsors are expected to interpret their data correctly despite possible discrepancies between language versions of the instrument.
At the same time, the trend influences the process of instrument selection and development. Today, many organizations do not leave testing until the end of the project but conduct thorough psychometric reviews before choosing an assessment. It seems reasonable considering the possibility of identifying potential issues beforehand rather than solving them later.
Besides, many stakeholders currently use the outputs from various surveys for further decision-making regarding programs and policies. Under such conditions, the issue gains new importance. Organizations using data to guide their operations have higher needs for validated instruments because findings might impact the provision of services or funding of programs.
It means that the discussion of validation services has changed significantly in recent years in terms of requirements from sponsors. Buyers are not satisfied with linguistic analysis performed without testing. On the contrary, they expect a provider to follow all standard requirements for evidence generation and evaluation of an instrument.
Nevertheless, the extent of activities performed to validate a questionnaire depends on the use of an instrument and a target population. Not all organizations need the most rigorous process to develop their tool. Sometimes, simpler approaches work equally well. Thus, organizations should choose an appropriate solution based on their needs.
