“…Still, we decided to use this combination on basis of the reasons mentioned above. The Rasch Model assumes that the probability P(X v,i ) of a person ν giving a certain answer X for an item i depends on two factors: (1) the item difficulty, σ i , and (2) the person's ability θ ν [28], which are estimated simultaneously on the same scale. This means, the numbers for person abilities and item difficulties can be directly compared.…”

Background With the onset of the COVID-19 pandemic at the beginning of 2020, the crucial role of hygiene in healthcare settings has once again become very clear. For diagnostic and for didactic purposes, standardized and reliable tests suitable to assess the competencies involved in “working hygienically” are required. However, existing tests usually use self-report questionnaires, which are suboptimal for this purpose. In the present study, we introduce the newly developed, competence-oriented HygiKo test instrument focusing health-care professionals’ hygiene competence and report empirical evidence regarding its psychometric properties. Methods HygiKo is a Situational Judgement Test (SJT) to assess hygiene competence. The HygiKo-test consists of twenty pictures (items), each item presents only one unambiguous hygiene lapse. For each item, test respondents are asked (1) whether they recognize a problem in the picture with respect to hygiene guidelines and, (2) if yes, to describe the problem in a short verbal response. Our sample comprised n = 149 health care professionals (79.1 % female; age: M = 26.7 years, SD = 7.3 years) working as clinicians or nurses. The written responses were rated by two independent raters with high agreement (α > 0.80), indicating high reliability of the measurement. We used Item Response Theory (IRT) for further data analysis. Results We report IRT analyses that show that the HygiKo-test is suitable to assess hygiene competence and that it allows to distinguish between persons demonstrating different levels of ability for seventeen of the twenty items), especially for the range of low to medium person abilities. Hence, the HygiKo-SJT is suitable to get a reliable and competence-oriented measure for hygiene-competence. Conclusions In its present form, the HygiKo-test can be used to assess the hygiene competence of medical students, medical doctors, nurses and trainee nurses in cross-sectional measurements. In order to broaden the difficulty spectrum of the current test, additional test items with higher difficulty should be developed. The Situational Judgement Test designed to assess hygiene competence can be helpful in testing and teaching the ability of working hygienically. Further research for validity is needed.

“…This model can be used to estimate unidimensional latent abilities [26]. The model assumes that the probability P(Xv,i) of a person ν giving a certain answer X for an item i depends on two factors: (1) the item difficulty, σi, and (2) the person's ability θν [28], which are estimated simultaneously on the same scale. This means, the numbers for person abilities and item difficulties can be directly compared.…”

Background: Since the onset of the Corona pandemic at the beginning of 2020, the extreme importance of hygiene has once again become very clear. In the medical context, it is not easy to find suitable test formats to assess the competencies involved in “working hygienically”. Pre-existing test formats usually use self-report questionnaires, which are suboptimal for this purpose. Methods: We designed a Situational Judgement Test (SJT) to assess hygiene competence. The SJT incorporates reliable measures and is a good predictor of job performance. The test consists of twenty pictures (items) presenting only one unambiguous hygiene lapse. Test respondents were asked (1) to note down whether they recognized a problem in the picture in respect of hygiene guidelines and (2), if yes, to describe the problem in a short verbal response. The sample comprised n = 149 health care professionals (79.1% female; age: M = 26.7 years, SD = 7.3 years) working as clinicians or nurses. The written responses were rated by two independent raters with high agreement (α > .80), indicating high reliability of the measurement. We then used Item Response Theory (IRT) for data analysis. Results: The reported IRT analyses show that the test is suitable to assess hygiene competence and that it is possible to distinguish between persons demonstrating different levels of ability for seventeen of the twenty items/pictures), expecially for the range of low to medium person abilities.Conclusions: The test in its present form can be used to assess the hygiene competence of medical students, medical doctors, nurses and trainee nurses in cross-sectional measurements. In order to broaden the difficulty spectrum of the current test, additional test items with higher difficulty should be developed. The Situational Judgement Test designed to assess hygiene competence can be helpful in testing and teaching the ability of working hygienically.

“…me of idea, n. Adto be of the of the ations of the idea through learning effects (claim II.3) do not have to be just theoretically formulated but can be already implemented also due to the character of the instruction for the verbal exams. Within our next step we address RQ 2 and the trainees' capability values as well as the difficulties of the Opportunity Recognition tasks/sub-items (Geiser & Eid 2010). As basis for this analysis the reports are coded dichotomously: value 0 was coded when there was no evidence for the postulated behavior, value 1 was coded when the postulated behavior could be observed in accordance with our OR-model (Table 1).…”
