Purpose: Establishing content validity for both new and existing patient-reported outcome (PRO) measures is central to a scientifically sound instrument development process. Methodological and logistical issues present a challenge in regard to determining the best practices for establishing content validity.
Methods: This paper provides an overview of the current state of knowledge regarding qualitative research to establish content validity based on the scientific methodological literature and authors' experience.
Results: Conceptual issues and frameworks for qualitative interview research, developing the interview discussion guide, reaching saturation, analysis of data, developing a theoretical model, item generation and cognitive debriefing are presented. Suggestions are offered for dealing with logistical issues regarding facilitator qualifications, ethics approval, sample recruitment, group logistics, taping and transcribing interviews, honoraria and documenting content validity.
Conclusions: It is hoped this paper will stimulate further discussion regarding best practices for establishing content validity so that, as the PRO field moves forward, qualitative research can be evaluated for quality and acceptability according to scientifically established principles.

Background/objectives: Host cell protein (HCP) content is a major attribute for biological and vaccine products that must be extensively characterized prior to product licensure. Enzyme Linked Immunosorbent Assay (ELISA) and Mass Spectrometry (MS) are conventional methods for quantitative host cell protein analysis in biologic and vaccine products. Both techniques are usually very tedious, labor-intensive, and challenging to transfer to other laboratories.

Understanding the factors that contribute to slope failures, such as soil saturation, is essential for mitigating rainfall-induced landslides. Cost-effective capacitive soil moisture sensors have the potential to be widely implemented across multiple sites for landslide early warning systems. However, these sensors need to be calibrated for specific applications to ensure high accuracy in readings.

Active pharmaceutical ingredient (API) content is a critical quality attribute (CQA) of amorphous solid dispersions (ASDs) prepared by spraying a solution of APIs and polymers onto the excipients in fluid bed granulator. This study presents four methods for quantifying API content during ASD preparation. Raman and three near-infrared (NIR) process analysers were utilized to develop methods for API quantification.
