Rollator User Satisfaction Survey in Germany with QUEST and NPS Scores

Forty-four regular rollator users in Germany participated in an exploratory cross-sectional study from June 2024 to April 2025. The dataset includes quantitative satisfaction scores from the QUEST 2.0 instrument and Net Promoter Score (NPS), alongside qualitative open-ended responses on usability and safety. Marcel Schmucker authored this study, which is licensed for reuse under CC-BY-4.0.

Use Cases

• Analyze correlations between device satisfaction (QUEST 2.0) and user recommendation behavior (NPS) based on the reported metrics.
• Identify common safety concerns and suggested product improvements based on the thematic summary of open-ended responses regarding brakes, suspension, and lighting.
• Study procurement pathways and training gaps for assistive devices based on data about prescription rates, medical supply store involvement, and training frequency.
• Model usage patterns and risk factors based on reported primary uses (walking, transport, seating) and accident rates in different environments.

Strengths

• Includes mixed-method data from 44 participants, combining standardized quantitative instruments (QUEST 2.0, NPS) with qualitative open-ended responses.
• Provides specific demographic context: median participant age of 85.5 years and 54.5% female representation.
• Reports concrete statistical results, including a QUEST 2.0 mean satisfaction score of 4.41 (SD 0.55) and a correlation with NPS (ρ = .433, p = .003).

Limitations

• Row count is unknown, which may limit suitability assessment for statistical modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• The sample of 44 participants, while informative, may limit the generalizability of findings.
