Health Literacy in the General Population in Belgium

April 23, 2019 updated by: Isabelle Bragard, University of Liege

Health Literacy in the General Population in Belgium: Associations and Determinants

The aims of the study are:

  • To measure health literacy (HL) levels in a sample composed of members of a health mutual (Solidaris), and its potential associations with several determinants (health, health services consumption, health behaviours...)
  • To identify potential groups at risk of a lower HL
  • To identify the determinants of HL level

Study Overview

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Health Literacy
Time Frame: At the inclusion in the study
The degree to which individuals can obtain, process and understand basic health information and services needed to make appropriate health decisions. It also includes the cognitive and social skills which determine the motivation and ability of individuals to gain access to, understand and use information in ways which promote and maintain good health. It is measured by the Health Literacy Questionnaire (HLQ) (Osborne et al., 2013), composed of 44 items (9 dimensions).
At the inclusion in the study

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
General health
Time Frame: At the inclusion in the study
Measured with the EQ-5D-5L (EuroQol Group, 1990), divided into 2 parts. The first part is composed of 5 items investigating 5 dimensions (mobility, autonomy, daily activities, pain, and anxiety and depression).
At the inclusion in the study
General health
Time Frame: At the inclusion in the study
Measured with the EQ-5D-5L (EuroQol Group, 1990), divided into 2 parts: the second part is composed of 1 Visual Analogue Scale (VAS, from 0 to 100), investigating the perceived health.
At the inclusion in the study
Chronic illnesses
Time Frame: At the inclusion in the study
Questions about the presence of chronic illness(es) are asked, along with their duration.
At the inclusion in the study
Body Mass Index
Time Frame: At the inclusion in the study
Calculated with the standard formula (weight/height²)
At the inclusion in the study
Feeling of stigma associated with the chronic illness
Time Frame: At the inclusion in the study
Measured with the Stigma Scale for Chronic Illnesses (Molina et al., 2013), which assesses enacted and internalised stigma. It is composed of 8 items. The responses for each item can be: 1 = Never, 2 = Rarely, 3 = Sometimes, 4 = Often, and 5 = Always. The raw summed score range is 8-40, with a higher score indicating a higher perceived stigma. Raw scores are then transformed into T-scores (a result of rescaling raw scores into standardized scores with a mean of 50 and a standard deviation of 10).
At the inclusion in the study
Satisfaction about health services
Time Frame: At the inclusion in the study
Investigation of the participant's satisfaction about hospitals, dentists, specialised physician, general practitioners, home care and Solidaris, through 6 questions ranging from 1 (very unsatisfied) to 5 (very satisfied).
At the inclusion in the study
Consumption behaviors
Time Frame: At the inclusion in the study
Tobacco, alcohol, fruits and vegetables consumption are investigated through 5 questions: do you smoke ? / If yes, what do you smoke? / How often do you drink alcohol? / How often do you eat fruits? / How often do you eat vegetables?
At the inclusion in the study
Physical activity
Time Frame: At the inclusion in the study
Investigated through 2 questions: during the last 7 days, how many days did you practice intense physical activity? / during the last 7 days, how many days did you practice moderate physical activity? For each question, answers range from 0 to 7.
At the inclusion in the study
Use of the Internet for health purposes
Time Frame: At the inclusion in the study
Investigated through 1 question: "how often do you use the Internet to search information about your health?". Answers range from 1 (never) to 5 (always).

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2017

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
June 30, 2018

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
