Background: Modern modeling techniques may potentially provide more accurate predictions of dichotomous outcomes than classical techniques. Objective: In this study, we aimed to examine the predictive performance of eight modeling techniques to predict mortality by frailty. Methods: We performed a longitudinal study with a 7-year follow-up. The sample consisted of 479 Dutch community-dwelling people, aged 75 years and older. Frailty was assessed with the Tilburg Frailty Indicator (TFI), a self-report questionnaire. This questionnaire consists of eight physical, four psychological, and three social frailty components. The municipality of Roosendaal, a city in the Netherlands, provided the mortality dates. We compared modeling techniques, such as support vector machine (SVM), neural network (NN), random forest, and least absolute shrinkage and selection operator, as well as classical techniques, such as logistic regression, two Bayesian networks, and recursive partitioning (RP). The area under the receiver operating characteristic curve (AUROC) indicated the performance of the models. The models were validated using bootstrapping. Results: We found that the NN model had the best validated performance (AUROC=0.812), followed by the SVM model (AUROC=0.705). The other models had validated AUROC values below 0.700. The RP model had the lowest validated AUROC (0.605). The NN model had the highest optimism (0.156). The predictor variable “difficulty in walking” was important for all models. Conclusions: Because of the high optimism of the NN model, we prefer the SVM model for predicting mortality among community-dwelling older people using the TFI, with the addition of “gender” and “age” variables. External validation is a necessary step before applying the prediction models in a new setting.

Abstract: Combined lifestyle interventions (CLI) are focused on guiding clients with weight-related health risks into a healthy lifestyle. CLIs are most often delivered through face-to-face sessions with limited use of eHealth technologies. To integrate eHealth into existing CLIs, it is important to identify how behavior change techniques are being used by health professionals in the online and offline treatment of overweight clients. Therefore, we conducted online semi-structured interviews with providers of online and offline lifestyle interventions. Data were analyzed using an inductive thematic approach. Thirty-eight professionals with (n = 23) and without (n = 15) eHealth experience were interviewed. Professionals indicate that goal setting and action planning, providing feedback and monitoring, facilitating social support, and shaping knowledge are of high value to improve physical activity and eating behaviors. These findings suggest that it may be beneficial to use monitoring devices combined with video consultations to provide just-in-time feedback based on the client’s actual performance. In addition, it can be useful to incorporate specific social support functions allowing CLI clients to interact with each other. Lastly, our results indicate that online modules can be used to enhance knowledge about health consequences of unhealthy behavior in clients with weight-related health risks.

Op 8 januari 2020 verdedigde ik mijn proef - schrift bij de Rijksuniversiteit Groningen. Het proefschrift richt zich op het vergroten van inzicht in de aard en de omvang van potentiële complicaties na het toepassen van manueeltherapeutische handelingen aan de cervicale wervelkolom bij mensen met nekpijn en/of hoofdpijn. Zowel onder leken als onder zorgprofessionals bestaat de veronderstelling dat manueeltherapeutische handelingen die worden toegepast aan de cervicale wervelkolom, kunnen leiden tot complicaties. Er is tot nu toe geen duidelijk causaal verband gevonden tussen de handelingen en ernstige complicaties. Bovendien wordt slechts sporadisch gepubliceerd over casuïstiek met ernstige complicaties die tijdens of na manuele behandelingen van de cervicale wervelkolom ontstaan zijn. De schattingen van het voorkomen van complicaties variëren enorm. Daarnaast is niet duidelijk welke patiënten een hoger of lager risico lopen op dergelijke complicaties.

Background: Behaviour change techniques (BCTs) can be employed to support a healthy lifestyle for people with intellectual disabilities. The aim of this study is to determine whether and which BCTs are used by direct support professionals (DSPs) for supporting healthy lifestyle behaviour of people with moderate to profound intellectual disabilities. Method: Direct support professionals (n = 18) were observed in their daily work using audio-visual recordings. To code BCTs, the Coventry Aberdeen London Refined (CALO-RE-NL) taxonomy was employed. Results: Direct support professionals used 33 BCTs out of 42. The most used BCTs were as follows: ‘feedback on performance’, ‘instructions on how to perform the behaviour’, ‘doing together’, ‘rewards on successful behaviour’, ‘reward effort towards behaviour’, ‘DSP changes environment’, ‘graded tasks’, ‘prompt practice’ and ‘model/demonstrate behaviour’. Conclusions: Although a variety of BCTs is used by DSPs in their support of people with moderate to profound intellectual disabilities when facilitating healthy lifestyle behaviour, they rely on nine of them.

Background: Professional caregivers are important in the daily support of lifestyle change for adults with mild intellectual disabilities; however, little is known about which behaviour change techniques (BCTs) are actually used. This study aims to gain insight in their use for lifestyle behaviour change using video observations.Methods: Professional caregivers (N = 14) were observed in daily work supporting adults with mild intellectual disabilities. Videos were analysed using the Coventry Aberdeen London Refined (CALO-RE-NL) taxonomy and BCTs utilised were coded.Results: Twenty one out of 40 BCTs were used by professional caregivers. The BCTs ‘Information about others' approval’, ‘Identification as role model’, ‘Rewards on successful behaviour’, ‘Review behavioural goals’ and ‘Instructions on how to perform the behaviour’ were most employed.Conclusion: Professional caregivers used BCTs to support healthier lifestyle behaviour of adults with mild intellectual disabilities. However, most promising of them as defined previous by professionals were rarely used by professional caregivers.

Aim Direct Support Professionals (DSPs) provide important lifestyle behaviour support for people with intellectual disabilities (ID). They can use behaviour change techniques (BCTs) to do this. We aimed to evaluate which BCTs are used for supporting healthy lifestyle behaviour of people with moderate to profound ID by DSPs. Method 18 DSPs were observed in their daily work with audio-visual recordings. The Coventry Aberdeen London Refined (CALO-RE-NL) taxonomy was used for coding BCTs. Differences in the characteristics of people with ID and DSPs in relation to the used BCTs were evaluated.Results Most of the coded BCTs were used by DSPs (33 BCTs out of 42), but they rely heavily on nine of them. DSPs used ‘feedback on performance’, ‘instructions on how to perform the behaviour’, and ‘doing together’ mostly. No statistical differences were found for the characteristics of people with ID or DSPs for the top nine used BCTs.Conclusion DSPs mostly rely on nine BCTs. Although no statistical differences were found, DSPs use more BCTs for people with more severe ID. DSPs who support people with severe or profound ID are more aware of demonstrating, setting graded tasks and encouraging people with ID to practice healthy lifestyle.

BACKGROUND: Cystic fibrosis is an inherited life-limiting disorder, characterised by pulmonary infections and thick airway secretions. Chest physiotherapy has been integral to clinical management in facilitating removal of airway secretions. Conventional chest physiotherapy techniques (CCPT) have depended upon assistance during treatments, while more contemporary airway clearance techniques are self-administered, facilitating independence and flexibility.OBJECTIVES: To compare CCPT with other airway clearance techniques in terms of their effects on respiratory function, individual preference, adherence, quality of life and other outcomes.SEARCH STRATEGY: We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group trials register which comprises references identified from comprehensive electronic database searches and handsearching of relevant journals and abstract books of conference proceedings. We also searched CINAHL from 1982 to 2002 and AMED from 1985 to 2002. Date of most recent search: January 2004.SELECTION CRITERIA: Randomised or quasi-randomised clinical trials including those with a cross-over design where CCPT was compared with other airway clearance techniques. Studies of less than seven days duration were excluded.DATA COLLECTION AND ANALYSIS: Two reviewers allocated quality scores to relevant studies and independently extracted data. If we were unable to extract data, we invited authors to submit their data. We excluded studies from meta-analysis when data were lost or study design precluded comparison. For some continuous outcomes, we used the generic inverse variance method for meta-analysis of data from cross-over trials and data from parallel-designed trials were incorporated for comparison. We also examined efficacy of specific techniques and effects of treatment duration.MAIN RESULTS: Seventy-eight publications were identified by the searches. Twenty-nine of these were included, representing 15 data sets with 475 participants. There was no difference between CCPT and other airway clearance techniques in terms of respiratory function measured by standard lung function tests. Studies undertaken during acute exacerbations demonstrated relatively large gains in respiratory function irrespective of airway clearance technique. Longer-term studies demonstrated smaller improvements or deterioration over time. Ten studies reported individual preferences for technique, with participants tending to favour self-administered techniques. Heterogeneity in the measurement of preference precluded these data from meta-analysis.AUTHORS' CONCLUSIONS: This review demonstrated no advantage of CCPT over other airway clearance techniques in terms of respiratory function. There was a trend for participants to prefer self-administered airway clearance techniques. Limitations of this review included a paucity of well-designed, adequately-powered, long-term trials.

Researchers worldwide have identified affective benefits of improvisational drama techniques (IDTs) on foreign language (FL) learners. Yet the characteristics of professional development programmes (PDPs) that could lead to long-term integration of drama among FL teachers appear largely undiscovered. Through expert interviews, a needs analysis questionnaire and a literature review, this study aimed to determine which design principles a PDP must fulfil to effectively address educational challenges surrounding IDT-implementation. The findings revealed that such training calls for a symbiosis between practical considerations, namely school environment and training conditions, and tapping into a mindset among FL teachers that allows them to (re)discover core beliefs and carry out IDTs with ‘artistry’.
