Assessing right to die attitudes: a conceptually guided measurement model

Area of Science:

• Medical Ethics
• Psychology
• Sociology

Background:

• Research on attitudes toward euthanasia and right to die (RTD) is hindered by conceptual and methodological issues.
• Existing scales may not adequately differentiate between various RTD constructs.

Purpose of the Study:

• To present conceptual and measurement models for assessing attitudes toward euthanasia and RTD constructs.
• To guide the development and refinement of scales measuring these attitudes.
• To improve the advancement of research in this critical area.

Main Methods:

• A conceptual model defining RTD constructs based on locus of decision and locus of action.
• A measurement model considering construct specificity, individual characteristics, and conviction.
• Evaluation of an existing euthanasia attitude scale using the proposed models.

Main Results:

• The conceptual model differentiates RTD constructs by locus of decision and action.
• Health status and age are identified as key factors influencing attitudes and defining attributes.
• The measurement model emphasizes specificity, individual characteristics, and conviction for accurate assessment.

Conclusions:

• The proposed models offer a framework for advancing research on attitudes toward euthanasia and RTD.
• Improved conceptualization and measurement are crucial for understanding public and individual stances.
• Application of these models can enhance the validity and reliability of attitude scales.
