Adequate gross motor skills are an essential aspect of a child’s healthy development. Where physical education (PE) is part of the primary school curriculum, a strong curriculum-based emphasis on evaluation and support of motor skill development in PE is apparent. Monitoring motor development is then a task for the PE teacher. To fulfill this task, teachers need adequate tools. The 4-Skills Scan is a quick and easily manage- able gross motor skill instrument; however, its validity has never been assessed. Therefore, the purpose of this study was to assess the construct and concurrent validity of both 4-Skills Scans (version 2007 and version 2015). A total of 212 primary school children (6-12 years old) was requested to participate in both versions of the 4-Skills Scan. For assessing construct validity, children covered an obstacle course with video recordings for observation by an expert panel. For concurrent validity, a comparison was made with the M-ABC-2, by calculating Pearson correlations. Multivariable linear regression analyses were performed to determine the contribution of each subscale to the construct of gross motor skills, according to the M-ABC-2 and the expert panel. Correlations between the 4-Skills Scans and expert valuations were moderate, with coefficients of .47 (version 2007) and .46 (version 2015). Correlations between the 4-Skills Scans and the M-ABC-2 (gross) were moderate (.56) for version 2007 and high (.64) for version 2015. It is concluded that both versions of the 4-Skills Scans are satis- factory valid instruments for assessing gross motor skills during PE lessons.
Objective To evaluate the validity and reliability of the Dutch STarT MSK tool in patients with musculoskeletal pain in primary care physiotherapy. Methods Physiotherapists included patients with musculoskeletal pain, aged 18 years or older. Patients completed a questionnaire at baseline and follow-up at 5 days and 3 months, respectively. Construct validity was assessed by comparing scores of STarT MSK items with reference questionnaires. Pearson’s correlation coefficients were calculated to test predefined hypotheses. Test-retest reliability was evaluated by calculating quadratic-weighted kappa coefficients for overall STarT MSK tool scores (range 0–12) and prognostic subgroups (low, medium and high risk). Predictive validity was assessed by calculating relative risk ratios for moderate risk and high risk, both compared with low risk, in their ability to predict persisting disability at 3 months. Results In total, 142 patients were included in the analysis. At baseline, 74 patients (52.1%) were categorised as low risk, 64 (45.1%) as medium risk and 4 (2.8%) as high risk. For construct validity, nine of the eleven predefined hypotheses were confirmed. For test-retest reliability, kappa coefficients for the overall tool scores and prognostic subgroups were 0.71 and 0.65, respectively. For predictive validity, relative risk ratios for persisting disability were 2.19 (95% CI: 1.10–4.38) for the medium-risk group and 7.30 (95% CI: 4.11–12.98) for the highrisk group. Conclusion The Dutch STarT MSK tool showed a sufficient to good validity and reliability in patients with musculoskeletal pain in primary care physiotherapy. The sample size for high-risk patients was small (n = 4), which may limit the generalisability of findings for this group. An external validation study with a larger sample of high-risk patients (�50) is recommended.
To evaluate the construct validity and the inter-rater reliability of the Dutch Activity Measure for Post- Acute Care “6-clicks” Basic Mobility short form measuring the patient’s mobility in Dutch hospital care. First, the “6-clicks” was translated by using a forward-backward translation protocol. Next, 64 patients were assessed by the physiotherapist to determine the validity while being admitted to the Internal Medicine wards of a university medical center. Six hypotheses were tested regarding the construct “mobility” which showed that: Better “6-clicks” scores were related to less restrictive pre-admission living situations (p¼0.011), less restrictive discharge locations (p¼0.001), more independence in activities of daily living (p¼0.001) and less physiotherapy visits (p<0.001). A correlation was found between the “6-clicks” and length of stay (r¼0.408, p¼0.001), but not between the “6-clicks” and age (r¼0.180, p¼0.528). To determine the inter-rater reliability, an additional 50 patients were assessed by pairs of physiotherapists who independently scored the patients. Intraclass Correlation Coefficients of 0.920 (95%CI: 0.828–0.964) were found. The Kappa Coefficients for the individual items ranged from 0.649 (walking stairs) to 0.841 (sit-to-stand). The Dutch “6-clicks” shows a good construct validity and moderate-toexcellent inter-rater reliability when used to assess the mobility of hospitalized patients.

Inzet van serious games als scholingsinstrument voor zorgprofessionals of als patiëntinterventie neemt sterk toe. Serious games kunnen kosten besparen en zorgkwaliteit verbeteren. (Potentiële) afnemers vragen, in lijn met het medische onderzoeksparadigma, vaak naar de klinische effectiviteit (internal validity) van deze games. Het gros van de Nederlandse game-ontwikkelaars bestaat echter uit kleine ondernemingen die het aan middelen en expertise ontbreekt om de hiervoor benodigde longitudinale onderzoekstrajecten uit te voeren. Tegelijkertijd tonen mkb’ers, meestal zonder ervan bewust te zijn, tijdens het game-ontwikkelproces al verschillende validiteitsvormen aan volgens het design-onderzoeksparadigma (face validity, construct validity, e.d.). Door dit niet bij hun afnemers kenbaar te maken, komt een constructieve dialoog over validiteit moeilijk op gang en lopen mkb’ers opdrachten mis. Het ontbreekt hen aan een begrippenkader en praktische handvatten. Bestaande raamwerken zijn nog te theorie-gedreven. Om mkb’ers te helpen de 'clash' te overbruggen tussen het medische en het design-onderzoeksparadigma, ontwikkelen lectoraten ICT-innovaties in de Zorg (Hogeschool Windesheim, penvoerder) en Serious Gaming (NHL Stenden Hogeschool) samen met elf mkb’ers, afnemers, studenten en experts in een learning community drie hulpmiddelen: •Checklist: praktische mkb-richtlijnen voor het vaststellen van validiteit; •Beslisboom: op basis waarvan mkb’ers onderbouwd de juiste validatiemethode kunnenselecteren; •Serious game: om samen met (potentiële) afnemers te spelen, zodat verschillende soortenvaliditeit expliciet benoemd worden. De hulpmiddelen worden inhoudelijk gevoed door casestudies waarin mkb’ers gevolgd worden in hoe validiteit momenteel wordt vastgesteld en geëxpliciteerd in het ontwikkelproces. Vervolgens brengen we de ontworpen hulpmiddelen in de mkb-praktijk voor evaluatie. Opgeleverde hulpmiddelen stellen mkb’ers in staat werkbare validatiemethoden toe te passen gedurende het game-ontwikkelproces om acceptabele bewijslast op te leveren voor potentiële afnemers, waardoor hun marktpositie versterkt. Ook draagt het project bij aan operationalisering van bestaande raamwerken en kunnen de hulpmiddelen in game design-curricula worden geïncorporeerd.
