Health and Quality of Life Outcomes
|July 3, 2019
Summary
This pilot study explored deriving a German value set for the Short-Form Six-Dimension (SF-6D) using deliberation and multi-criteria decision analysis (MCDA). Consensus on a value set was not reached due to challenges in weighting and group dynamics.
Area of Science:
- Health Economics
- Decision Science
- Quality of Life Research
Background:
- Growing interest in integrating value judgments into cost-utility analyses.
- Exploration of deliberation and multi-criteria decision analysis (MCDA) for transparent value integration.
- Need for a German value set for the Short-Form Six-Dimension (SF-6D) based on societal values.
Purpose of the Study:
- To pilot a consensus process for deriving a German value set for the SF-6D.
- To integrate societal perspectives on health-related quality of life using a deliberative MCDA approach.
- To assess the feasibility of deriving SF-6D scores and weights from a self-determined and independent life perspective.
Main Methods:
- A one-day consensus conference employing a deliberative process and the MACBETH (Measuring Attractiveness by a Categorical Based Evaluation Technique) MCDA method.
- Participants qualitatively rated pairwise comparisons of SF-6D health states.
- Scoring and weighting of SF-6D dimensions conducted in parallel group sessions and a subsequent plenary assembly.
Main Results:
- 34 participants recruited; consensus reached on SF-6D scores for most dimensions, but not pain.
- No consensus achieved on dimension weights due to disagreements on the acceptability of trade-offs.
- Participants identified large plenary group size and the weighting procedure as obstacles to consensus.
Conclusions:
- The pilot demonstrated a consensus-based approach for valuing health-related quality of life.
- Further research is required to refine deliberative processes for quantifiable outcomes.
- Recommendations include exploring smaller group sizes, longer conference durations, and alternative MCDA functions.

01:21Pilot and Numeric Relaying
483
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

01:21Health Literacy
5.2K
Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...

2.5K
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
