Reliability and validity of the German “Evidence-Based Practice Confidence (EPIC) Scale” for allied health professionals
Get PDFIntroduction: The Evidence-Based Practice Confidence (EPIC) Scale measures health professionals’ self-efficacy associated with evidence-based practice activities. The scale has been cross-culturally translated into German together with physical therapists. To support its use in German-speaking countries, the measurement properties of the scale need to be determined. Therefore, the primary objective of this study was to assess the measurement properties of the German EPIC scale. In a preparatory step, we aimed to evaluate the comprehensibility of the scale among German-speaking occupational therapists, speech and language therapists, and nurses.
Methods: First, semi-structured cognitive interviews were used to evaluate the comprehensibility of the EPIC scale. Second, a longitudinal online survey with repeated measures (baseline and retest survey) was conducted. The target group included physical therapists, occupational therapists, speech and language therapists, and nurses from Germany, Austria, and Switzerland. Reliability, responsiveness, and validity were evaluated using internal consistency, test-retest reliability, standard error of measurement, known-groups method, exploratory factor analysis and the minimal detectable change, respectively.
Results: Comprehensibility of the German EPIC scale was confirmed by eleven health care professionals (four occupational therapists, two speech and language therapists, five nurses). The baseline and the retest surveys were completed by 708 and 222 participants, respectively. The measure demonstrated an internal consistency of .930, with an intraclass correlation coefficient (ICC) for test-retest reliability of .936 (95% CI: .917 to .951). The standard error of measurement was 4.92, and the minimal detectable change at the 95% confidence level was 6.02. All hypotheses in the known-groups method were confirmed, and construct validity was acceptable. Factor analysis revealed two main factors affecting the results of the scale.
Conclusion: The findings provide evidence that supports the use of the German EPIC scale among health professionals. For instance, it can be used to evaluate self-efficacy during EBP training.Hintergrund: Die „Evidence-Based Practice Confidence Scale“ (EPIC-Skala) misst die Selbstwirksamkeit von Angehörigen der Gesundheitsberufe bei Aktivitäten der evidenzbasierten Praxis. Die englischsprachige Skala wurde 2019 ins Deutsche übersetzt und anschließend mit Physiotherapeut*innen interkulturell adaptiert. Jedoch kann die Skala im deutschsprachigen Raum bislang nicht verwendet werden, da noch keine Bestimmung der psychometrischen Gütekriterien durchgeführt wurde. Deshalb ist das primäre Ziel dieser Studie die Ermittlung der psychometrischen Gütekriterien der deutschen EPIC-Skala. In einem vorbereitenden Schritt sollte die Verständlichkeit der Skala bei deutschsprachigen Ergotherapeut*innen, Logopäd*innen und Gesundheits- und Krankenpfleger*innen evaluiert werden.
Methode: Zunächst wurde die Verständlichkeit der EPIC-Skala anhand von semistrukturierten kognitiven Interviews untersucht. In einem zweiten Schritt wurde eine Online-Umfrage im Längsschnittdesign durchgeführt, wobei zunächst eine Basiserhebung und anschließend eine Retest-Erhebung stattfand. Die Zielgruppe der Untersuchung bildeten Physiotherapeut*innen, Ergotherapeut*innen, Logopäd*innen und Gesundheits- und Krankenpfleger*innen aus Deutschland, Österreich und der Schweiz. Die Reliabilität, Responsivität und Validität wurden anhand der internen Konsistenz, der Test-Retest-Reliabilität, des Standardmessfehlers, der Known-Groups-Methode, der explorativen Faktorenanalyse und der minimalen nachweisbaren Veränderung beurteilt.
Ergebnisse: Die Verständlichkeit der deutschen EPIC-Skala wurde von elf Angehörigen der Gesundheitsberufe (vier Ergotherapeut*innen, zwei Logopäd*innen, fünf Gesundheits- und Krankenpfleger*innen) bestätigt. Die Baseline- und Retest-Erhebungen wurden von 708 bzw. 222 Teilnehmenden abgeschlossen. Die Berechnungen zeigten eine interne Konsistenz von .930, mit einer Intraklassen-Korrelation für die Test-Retest-Reliabilität von .936 (95% CI: .917 - .951). Der Standardmessfehler betrug 4,92 und der minimale messbare Unterschied 6,02 (95%-Konfidenzintervall). Alle Hypothesen in der Known-Groups-Methode wurden bestätigt, sodass eine akzeptable Konstruktvalidität festgestellt wurde. Die Faktoranalyse ergab zwei Faktoren für die Skala.
Schlussfolgerung: Die Ergebnisse unterstützen die Anwendung der deutschen Version der EPIC-Skala durch Angehörige der Gesundheitsfachberufe, insbesondere bei der Evaluation von Fortbildungen zur Vermittlung von Kompetenzen im evidenzbasierten Arbeiten

Barriers and facilitators to conducting randomised controlled trials within routine care of neurorehabilitation centres: a qualitative study
No full textAbstract Background Randomised controlled trials (RCTs) are considered the gold standard for generating clinical evidence. The focus on high internal validity in RCTs challenges the external validity and generalisability of findings, potentially hindering their application in routine care. In neurorehabilitation, limited literature addresses conducting RCTs feasibly and efficiently. We investigated barriers and facilitators to conducting RCTs within routine care of neurorehabilitation centres from the perspective of stakeholders in neurorehabilitation in Germany and Austria. Methods We conducted semi-structured interviews with stakeholders in neurorehabilitation from four centres in Germany and Austria, informed by the Theoretical Domains Framework (TDF) and the Capability, Opportunity, Motivation and Behaviour model (COM-B). Employing a hybrid approach, the interview analysis integrated both deductive, theory-driven analysis based on the TDF domains and COM-B model and inductive, reflexive thematic analysis. Results Twelve stakeholders (4 physicians, 4 therapy managers, 4 therapists; 5 females, 7 males; with research experience spanning 0–40 years) were interviewed. Key barriers to conducting RCTs in neurological rehabilitation centres include limited financial, human, and time resources, high clinical workloads, and a lack of interest of some therapists. Ineffective leadership, perceived lack of research expertise, and communication issues were also significant barriers. Social influence factors such as lack of employer support and inadequate training access further contributed to the challenges. Additionally, barriers included insufficient research infrastructure, limited space, internal power struggles, and rigid cost bearer specifications. Key facilitators included physicians’ and therapists’ motivation to advance the field, contribute to knowledge, and to prioritise patient health. Support from supervisors, joint decision-making, and efficient organisation were crucial facilitators. Flexible therapy planning, mutual support, and interdisciplinary collaboration also played important roles. Conclusion Our results suggest that increasing professional development and understanding, along with providing adequate financial, human, time, and spatial resources to support research endeavours, implementing effective communication strategies to enhance interdisciplinary collaboration and coordination among team members may contribute to increased motivation and facilitate RCTs within the setting of neurorehabilitation centres.
