Objective swallowing outcomes measure the physical swallowing function, while subjective outcomes measure swallowing perception. A test for swallowing capacity, measuring the ingestion of all consistencies is currently not available. Therefore, the Swallowing Proficiency for Eating And Drinking (SPEAD) test was developed. It entails the timed ingestion of thin liquid, thick liquid and solid. In this study, its feasibility, reliability and validity were evaluated in patients with dysphagia after treatment for head and neck cancer (HNC) and healthy participants. Thirty-eight HNC patients and forty healthy participants were enrolled in this study and performed the SPEAD test three times. Video recordings of the test were evaluated three times by one observer, and once by three additional observers, to assess test-retest, intra-rater and inter-rater reliability. Validity was assessed by calculating effect sizes for the difference between results of patients and healthy participants and by evaluating correlations with objective (e.g., videofluoroscopy and functional oral intake scale) and subjective (e.g., SWAL-QOL) swallowing outcomes. Test-retest, intra-rater and inter-rater reliability of ingestion duration was good to excellent. All hypotheses with regard to magnitude and direction of correlations were confirmed, supporting construct validity of the test. Our initial results suggest that the SPEAD test reliably measures the transport capacity of the upper digestive tract (in grams per second) and that this test can be useful to objectively evaluate and monitor the (safe) swallowing capacity in HNC patients, in both research as well as daily clinical practice.

Rural children are a largely understudied population in language and literacy research, despite the fact that these children often enter school with delays in their language development. Since most rural areas suffered from so-called selective rural outmigration, many parents in rural areas are lower or middle educated. The home literacy climate, however, depends not only on the educational level of parents, but also on their lifestyle. In this study, we examined whether parental educational level and literacy use – as a feature of parental lifestyle – predict the language skills of children in Grade 1 in Northeast Netherlands. Structural equation modelling analyses revealed that the effect of parental literacy use on code-related skills is only significant in K-1 and K-2. In Grade 1, however, literacy use had a modest effect on oral language skills. The findings stress the importance of parents’ literacy use for informational purposes.

In this paper we describe our work in progress on the development of a set of criteria to predict text difficulty in Sign Language of the Netherlands (NGT). These texts are used in a four year bachelor program, which is being brought in line with the Common European Framework of Reference for Languages (Council of Europe, 2001). Production and interaction proficiency are assessed through the NGT Functional Assessment instrument, adapted from the Sign Language Proficiency Interview (Caccamise & Samar, 2009). With this test we were able to determine that after one year of NGT-study students produce NGT at CEFR-level A2, after two years they sign at level B1, and after four years they are proficient in NGT on CEFR-level B2. As a result of that we were able to identify NGT texts that were matched to the level of students at certain stages in their studies with a CEFR-level. These texts were then analysed for sign familiarity, morpheme-sign rate, use of space and use of non-manual signals. All of these elements appear to be relevant for the determination of a good alignment between the difficulty of NGT signed texts and the targeted CEFR level, although only the morpheme-sign rate appears to be a decisive indicator
