Background:

Subjective phenomena pose significant challenges in drug trials, impacting reliability and validity.
Traditional methods often struggle to adequately address issues of control, measurement, and analysis related to subjective data.
Advances in clinical pharmacology are crucial for overcoming these inherent difficulties.

Purpose of the Study:

To identify and illustrate the key problems arising from subjective phenomena in drug trials.
To present recent advances in clinical pharmacology aimed at mitigating these challenges.
To provide a detailed discussion on the control of drug compliance, questionnaire validity, and observer/observation subjectivity.

Main Methods:

Illustrative examples are used to demonstrate problems in control, measurement, and analysis.
Discussion of recent advances in clinical pharmacology.
Detailed examination of drug compliance control, questionnaire validity, observer bias, and observation subjectivity.
Presentation of statistical analysis methods for qualitative data.

Main Results:

Identified three core problem areas: control, measurement, and analysis of subjective phenomena.
Highlighted the importance of controlling drug compliance and ensuring questionnaire validity.
Emphasized the impact of observer and observation subjectivity on trial outcomes.
Demonstrated the application of statistical analysis for qualitative data in drug trials.

Conclusions:

Addressing subjective phenomena is critical for the integrity of drug trials.
Recent advances in clinical pharmacology offer effective strategies for managing subjective data.
Improved methods for control, measurement, and analysis enhance the reliability of clinical trial findings.
