Job description

This post-doc project ‘Validating person-specific measurements’ is part of the larger e-Health Junior NWA consortium project:

The e-Health junior consortium aims to improve the quality of life of children and young adults who suffer from a chronic illness. They do this with an interdisciplinary team of various scientists, game-designers, children/young adults and companies, by developing eHealth applications that contribute to resilience and self-awareness, and making and keeping those available to children and young adults that have a chronic illness. 

More information on e-Health Junior is available (in Dutch) here.

Project on Validating person-specific measurements:

Background: Novel methods and technology make it possible to collect many repeated measures for individual persons, for example via the Experience Sampling Method (ESM) or Ecological Momentary Assessments (EMA), and smart phone applications, such as those developed for the eHealth Junior project. One aim of collecting such data is to track individuals over time and provide them with personalized feedback to inform about how they are doing, and to potentially influence their behaviors, feelings, and cognitions. In order to do this well and responsibly, it is essential that the intensive longitudinal data collected is valid. Given that the data, analyses, and feedback are provided on a person-specific and often item-specific level, the validity of these measurements also needs to be evaluated on a person- and item-specific level.

The project: The candidate will (further) develop tools and establish quality criteria for evaluating the person- and item-specific reliability of Experience Sampling data. Other measures of validity aside from reliability may also be evaluated. To these ends, the candidate will use both simulation studies, and available empirical intensive longitudinal data. The studies will provide knowledge and tools relevant for evaluating Experience Sampling measurements in general, but also need to connect to specific questions that are particularly relevant for the e-Health junior applications.

Steps the candidate is expected to take during the project:

  • Consider multiple methods for evaluating reliability/validity in ESM;
  • Evaluate consequences of imperfect reliability (measurement error) on common ESM analysis techniques (e.g., dynamic networks/vector autoregressive modeling/dynamic SEM);
  • Particularly, evaluate the impact on the specific types of feedback that may be provided to the children via the eHealth junior applications;
  • Create a simple application to visualize certain consequences of imperfect reliability on results;
  • Evaluate reliability/validity of commonly used ESM items in the context of the eHealth Junior applications.
