BACKGROUND: Older adults want to preserve their health and autonomy and stay in their own home environment for as long as possible. This is also of interest to policy makers who try to cope with growing staff shortages and increasing health care expenses. Ambient assisted living (AAL) technologies can support the desire for independence and aging in place. However, the implementation of these technologies is much slower than expected. This has been attributed to the lack of focus on user acceptance and user needs.OBJECTIVE: The aim of this study is to develop a theoretically grounded understanding of the acceptance of AAL technologies among older adults and to compare the relative importance of different acceptance factors.METHODS: A conceptual model of AAL acceptance was developed using the theory of planned behavior as a theoretical starting point. A web-based survey of 1296 older adults was conducted in the Netherlands to validate the theoretical model. Structural equation modeling was used to analyze the hypothesized relationships.RESULTS: Our conceptual model showed a good fit with the observed data (root mean square error of approximation 0.04; standardized root mean square residual 0.06; comparative fit index 0.93; Tucker-Lewis index 0.92) and explained 69% of the variance in intention to use. All but 2 of the hypothesized paths were significant at the P<.001 level. Overall, older adults were relatively open to the idea of using AAL technologies in the future (mean 3.34, SD 0.73).CONCLUSIONS: This study contributes to a more user-centered and theoretically grounded discourse in AAL research. Understanding the underlying behavioral, normative, and control beliefs that contribute to the decision to use or reject AAL technologies helps developers to make informed design decisions based on users' needs and concerns. These insights on acceptance factors can be valuable for the broader field of eHealth development and implementation.
In elite sports, a case is increasingly made for the structural inclusion of what we label as planned disruptions. These are structured and deliberate training activities whereby athletes are exposed to increased and/or changing demands under controlled circumstances. Despite the growing body of evidence in support of planned disruptions (Sarkar & Fletcher, 2017), there is a lack of knowledge on which strategies coaches use in an applied context and why they use them. The present study, therefore, aimed at exploring the different types of planned disruptions high-performance coaches use and the desired outcomes of these disruptions. To this end, thematic analysis (Braun, Clarke, & Weate, 2016) was used to analyze semistructured interviews with 9 talent development and elite-level coaches (M age = 42.9, SD = 8.3; 6 male, 3 female). Results indicated that coaches use a combination of 9 types of planned disruptions (i.e., location, competition simulation, punishments and rewards, physical strain, stronger competition, distractions, unfairness, restrictions, and outside the box). These strategies were used to familiarize athletes to pressure, create awareness, develop or refine personal resources, and promote team processes. Three additional themes emerged, namely, the surprise use of planned disruptions, periodization, and the impact on personal relationships. The findings in the present study can guide further applied and theoretical explorations of the use of planned disruptions.
In this thesis several studies are presented that have targeted decision making about case management plans in probation. In a case management plan probation officers describe the goals and interventions that should help offenders stop reoffending, and the specific measures necessary to reduce acute risks of recidivism and harm. Such a plan is embedded in a judicial framework, a sanction or advice about the sanction in which these interventions and measures should be executed. The topic of this thesis is the use of structured decision support, and the question is if this can improve decision making about case management plans in probation and subsequently improve the effectiveness of offender supervision. In this chapter we first sketch why structured decision making was introduced in the Dutch probation services. Next we describe the instrument for risk and needs assessment as well as the procedure to develop case management plans that are used by the Dutch probation services and that are investigated in this thesis. Then we describe the setting of the studies and the research questions, and we conclude with an overview of this thesis.
Een groeiende groep senioren woont steeds langer zelfstandig thuis en het is bekend dat bij deze doelgroep aandacht voor een gezond (eiwitrijk) voedingspatroon belangrijk is. Het HAS lectoraat Voeding & Gezondheid van Dr. A. Roodenburg richt zich met het onderzoeksprogramma ‘Voeding voor senioren’ op het voedingsgebruik en –gedrag van deze doelgroep. In een aantal reeds lopende projecten wordt onderzoek gedaan naar het verhogen van kennis en bewustzijn over het belang van hogere eiwitconsumptie bij deze doelgroep. Het huidige voorstel bouwt hierop voort en richt zich met name op het gedrag van senioren (aanschaf van eiwitrijke producten) en gaat onderzoeken welke factoren ten aanzien van kennis, houding en sociale druk (Theory of Planned Behavior) hierbij een rol spelen. Deze informatie kan worden ingezet om senioren te sturen op de diverse aspecten om hen zo te verleiden tot de gewenste actie (= verhogen eiwit-inname). Uitkomsten van dit onderzoek geven richting voor productontwikkeling, marketing en communicatie. Voor een sterke verbinding van onderzoek en onderwijs wordt dit onderzoek uitgevoerd door de postdoc (Dr. J Linschooten) en met diverse studententeams onder begeleiding van de postdoc. De nieuw verworven kennis zal terugkomen in het curriculum van diverse HAS opleidingen zoals Voedingsmiddelentechnologie, Food Innovation en de minor ‘Towards a Healthy Society’, als ook in een masterclass voor externe partners (bedrijven/ publieke instellingen) om bij te dragen aan een betere afstemming van het productaanbod op deze doelgroep. Het postdoc programma zal ook ruimte bieden voor een versterking van de algemene leerlijn ‘Onderzoeksvaardigheden’ om docenten en studenten van eerder genoemde opleidingen beter te begeleiden bij de ontwikkeling van deze competentie.
