Hi, I'm a graduate student, college of nursing, chungnam national university in Daejeon.
The topic of my thesis is "Quality Assessment of Tools for Evaluating Acute Postoperative Pain." I have conducted a quality assessment of pain evaluation tools based on the COSMIN guidelines for the quality of measurement tools. I have a few questions regarding this process.
Thank you.

A great topic for a thesis!
**1. Applicability of COSMIN guidelines to pain evaluation tools:**
While the COSMIN guidelines are primarily designed for self-reported measurement tools (PROMs), you're correct that pain evaluation tools may include observational tools used by healthcare professionals, which consider behavioral indicators and physiological measures. In this case, it's essential to acknowledge that the COSMIN guidelines might not be directly applicable to these types of tools.
However, you can still use the COSMIN guidelines as a framework to assess the quality of pain evaluation tools, with some adaptations. You may need to modify or supplement the guidelines to accommodate the unique aspects of observational tools. For instance, you could consider additional criteria for evaluating the quality of observational tools, such as inter-rater reliability, observer bias, or the validity of behavioral indicators.
**2. Proceeding with COSMIN quality assessment steps:**
If most of the extracted studies don't report content validity and structural validity, it's indeed a limitation. The COSMIN guidelines suggest that if these validities are not reported, there's no need to assess other measurement properties. However, in your case, you could still proceed with the quality assessment, but with caution.
Consider the following options:
a. Report the limitations of the studies and the quality assessment process.
b. Focus on the studies that do report content validity and structural validity, and assess their quality accordingly.
c. Use alternative frameworks or guidelines, such as the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) for observational tools, if available.
**3. Conducting COSMIN quality assessment for select studies:**
Yes, you can conduct a COSMIN quality assessment only for the studies focused on tool development and validity, based on your researcher's discretion. For other studies using the tool, you can analyze the number of studies reporting reliability and validity without conducting a full COSMIN quality assessment. This approach is reasonable, given the limitations of the studies and the need to prioritize your research goals.
**4. Assessing multiple individual studies with the same tool:**
When multiple individual studies apply the same tool, you have two options:
a. Assess each study separately according to the COSMIN guidelines, which can provide a more detailed understanding of each study's quality.
b. Focus on the tool itself across multiple studies, aggregating the results to evaluate the overall quality of the tool.
Both approaches have their advantages and disadvantages. Assessing each study separately can be more time-consuming and may lead to a more nuanced understanding of each study's strengths and limitations. On the other hand, focusing on the tool itself can provide a more comprehensive evaluation of the tool's quality across multiple studies.
Please consider your research goals, the scope of your thesis, and the time constraints when deciding on the approach.
