To demedicalise societal problems, the term Positive Health (PH) was introduced-a concept focused on the ability to adapt and to self-manage, in the face of physical, emotional and social challenges. The concept of PH receives broad attention, among others because a PH dialogue tool is intensively being used as a communication instrument while reflecting on patients' health, but a PH measurement instrument is not yet fully established. Recently, however, a 17-item PH measurement model was proposed. In this paper, a factor analysis and regression analyses were performed to test the factorial validity and concurrent validity of this PH measurement model based on a representative sample of the Dutch population (n = 1016, 50.0% women; age: from 15 until 39 = 29.8%, from 40 until 65 = 43.0%, older than 65 = 27.2%; education levels: low = 28.7%, medium = 42.6%, high = 28.7%). These tests are crucial to understand how well the PH measurement model is suitable as a measurement instrument. The factor analysis provided support for the factorial validity of the proposed PH measurement model. When comparing the proposed PH measurement model with domains of other measurements of health (i.e. BRS, HR-SWB, ICECAP, and EQ5D), to test the concurrent validity, the model explained more than half of the variance in measurements of the domains happiness (R-2 = 0.60) and overall self-rated health (R-2 = 0.57), but explained less than a quarter of the variance in measurements of autonomy (R-2 = 0.17 / R-2 = 0.13), personal growth (R-2 = 0.21), stability (R-2 = 0.20), self-care (R-2 = 0.15), and resilience (R-2 = 0.24). Two of the six domains of the PH measurement model-mental functioning and daily functioning-were weakly related to the other measurements of health. The results of this study imply that the PH measurement model is suitable to measure multiple dimensions of health. They also suggest that the PH measurement model may not be an encompassing measure for the concepts measured through other health measurements and might explain variance in health beyond these other measurements.

Show moreIntercultural competence is a crucial element of foreign language education. It is argued that the multi-faceted nature of intercultural competence implies that assessment of its construct is a complex process; as a consequence, its progress is difficult to measure. Although several tools for evaluating intercultural competence currently exist, research on their use in secondary school settings is scarce. This study reports on the development and validation of an instrument intended specifically for use in foreign language literature education. To this end, tangible learning objectives for intercultural literary competence were developed based on five dimensions of intercultural communicative competence (Byram, 1997) and six categories of literary competence (Witte, 2008). These objectives were re-formulated for implementation in a student questionnaire. Using exploratory and confirmatory factor analysis, the construct validity of the instrument was investigated among a sample of 164 secondary school students in the upper forms of pre-university education in the Netherlands. Although the results supported the hypothesized wo second-order factor structure, the model fit indices were less favourable compared to the fit indices of an alternative five first-order factor model. Subsequently, correlation and summability analyses were performed to test the reliability of the instrument. Future research and implications are discussed. Show less

Show moreIntroduction: Electroconvulsive therapy (ECT) is an important and effective treatment for depression. However, research on course trajectories of depressive symptoms during ECT is limited. Insight into putative differences in speed of response of depressive symptom dimensions may enable clinicians to optimally informpatients and their relatives. Therefore, we aim to examine course trajectories of depressive symptom dimensions in depressed older persons during ECT.Methods: Data were derived from the Mood Disorders in Elderly treated with Electro Convulsive Therapy study, including 110 persons, aged 55 years or more, with a current diagnosis of major depressive disorder and referred for ECT. Exploratory factor analysis was used to identify symptom dimensions, using the 10 depression items of the Montgomery-Asberg Depression Rating Scale (MADRS). Differences in course trajectories of symptom dimension during 2 weeks were examined by multilevel analyses.Results: Three symptom dimensionswere identified: a "mood," "melancholic," and "suicidal" dimension. Mood showed a significantly greater severity decline as compared with melancholic and suicidal at the 1-week follow-up. At the 2-week follow-up, both mood and melancholic demonstrated a significantly greater decline as compared with suicidal. However, because scores on the suicidality item of the Montgomery-Asberg Depression Rating Scale were already lower at baseline compared with the other items, a floor effect cannot be ruled out.Discussion: All symptom dimensions of depression showed a rapid response to ECT. Our findings did not support the general assumption that suicidal symptoms may be the first to improve. However, a floor effect on the suicidality item cannot be ruled out. Show less
