Background: The aim of this study is to validate a newly developed nurses' self-efficacy sources inventory. We test the validity of a five-dimensional model of sources of self-efficacy, which we contrast with the traditional four-dimensional model based on Bandura's theoretical concepts. Methods: Confirmatory factor analysis was used in the development of the newly developed self-efficacy measure. Model fit was evaluated based upon commonly recommended goodness-of-fit indices, including the χ2 of the model fit, the Root Mean Square Error of approximation (RMSEA), the Tucker-Lewis Index (TLI), the Standardized Root Mean Square Residual (SRMR), and the Bayesian Information Criterion (BIC). Results: All 22 items of the newly developed five-factor sources of self-efficacy have high factor loadings (range .40-.80). Structural equation modeling showed that a five-factor model is favoured over the four-factor model. Conclusions and implications: Results of this study show that differentiation of the vicarious experience source into a peer- and expert based source reflects better how nursing students develop self-efficacy beliefs. This has implications for clinical learning environments: a better and differentiated use of self-efficacy sources can stimulate the professional development of nursing students.
DOEL. De laatste jaren zijn er nieuwe vormen van praktijkleren ontwikkeld binnen verpleegkundige opleidingen. Het doel van deze studie is onderzoeken of stage lopen binnen een krachtige leeromgeving leidt tot een sterkere ontwikkeling van ervaren self-efficacy bij hbo-verpleegkundestudenten dan stage lopen in een reguliere omgeving. METHODE. Een quasi experimenteel design (non-equivalent pretest-posttest control group) is toegepast, waarbij gebruik is gemaakt van de General Self Efficacy scale (GSE). De populatie bestaat uit hbo-v-stagiaires (n = 109 meting 1, n = 92 meting 2). Respondenten zijn onderverdeeld in studenten stage lopend binnen krachtige leeromgevingen en studenten stage lopend binnen reguliere stageomgevingen. Verschilscores op de GSE zijn voor beide groepen getoetst op significantie via t-toetsen. RESULTAAT. Studenten binnen krachtige leeromgevingen vertonen als totale groep en gedifferentieerd naar stage-ervaring op meer items van de GSE significante toename dan studenten binnen reguliere stageomgevingen. CONCLUSIE EN DISCUSSIE. Stage lopen binnen een krachtige leeromgeving lijkt in grotere mate bij te dragen aan de ontwikkeling van ervaren self-efficacy van hbo-verpleegkundestudenten. Het meten van self-efficacy binnen leeromgevingen is een aanvulling op bestaande uitkomstmaten voor het meten van effecten voor studenten. Verder onderzoek naar de relatie tussen de bronnen van self-efficacy en krachtige leeromgevingen binnen verpleegkundige opleidingen wordt aanbevolen.
Abstract: Clinicians find it challenging to engage with patients who engage in self-harm. Improving the self-efficacy of professionals who treat self-harm patients may be an important step toward accomplishing better treatment of self-harm. However, there is no instrument available that assesses the self-efficacy of clinicians dealing with self-harm. The aim of this study is to describe the development and validation of the Self-Efficacy in Dealing with Self-Harm Questionnaire (SEDSHQ). This study tests the questionnaire’s feasibility, test-retest reliability, internal consistency, content validity, construct validity (factor analysis and convergent validity) and sensitivity to change. The Self-Efficacy in Dealing with Self-Harm Questionnaire is a 27-item instrument which has a 3-factor structure, as found in confirmatory factor analysis. Testing revealed high content validity, significant correlation with a subscale of the Attitude Towards Deliberate Self-Harm Questionnaire (ADSHQ), satisfactory test-retest correlation and a Cronbach’s alpha of 0.95. Additionally, the questionnaire was able to measure significant changes after an intervention took place, indicating sensitivity to change. We conclude that the present study indicates that the Self-Efficacy in Dealing with Self-Harm Questionnaire is a valid and reliable instrument for assessing the level of self-efficacy in response to self-harm.
