September 22, 2026 updated by: Prof. Dr. Sonia Lippke, Jacobs University Bremen gGmbH

Health Surveillance by Constructor University Bremen (CUB) to Assess Germany-wide Students' Health and Wellbeing - Explanatory Sequential Mixed-Methods Approach

The aim of Health Surveillance is to analyze and describe the state of health of students at Constructor University, key influencing factors and individual resources by using mixed-method design.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The aim of Health Surveillance, plus the additional research by means of qualitative interviews is to analyze and describe the state of stress and health of students at Constructor University (CU) by using a mixed-methods approach, as well as explore the association and mechanism between stress and health of students at CU (and employees at HAW Hamburg), key influencing factors and individual resources. In areas where there is a need for action, the Health Surveillance plus this project, the additional qualitative interviews can provide detailed insights and/or in-depth analyses. The Health Surveillance thus provides information on health-related topics and delivers scientifically sound information as a basis for health-promoting discussions in the subsequent follow-up process at various levels (e.g. faculties and departments). In addition, the Health Surveillance plus the additional interviews at CU contributes to comparability with surveys at other German universities through the use of validated and standardized measuring instruments and in-depth qualitative interviews with qualitative content analysis, as well as to add new constructs (i.e., artificial intelligence and digital technology use) as well as democratic competences, as this turned out to be new and important factors. Main hypotheses are

  1. The Health Surveillance gives insights into the state of stress and health of students at CU, key influencing factors and individual resources by using a mixed-methods approach.
  2. With the Health Surveillance, health promotion at CU by using a mixed-methods approach, as well as explore the association and mechanism between stress and health of students at CU (and employees at HAW Hamburg), can be guided, and the promotion of mental health (including the reduction of loneliness and discrimination) can be strengthened.
  3. The health of students (and employees at HAW Hamburg), their perceived stress, loneliness and discrimination/minorization (disadvantage) as well as substance use, interrelates with participation in health-promoting activities?
  4. Recommendations can be derived for qualification and skills training of multipliers for health-promoting behavior (e.g., J-peers)?

In the qualitative phase, the inclusion criteria are English or Chinese language and between 18-30 years old. Before the start of the survey period and directly before the start of the online survey or interview, all participants will receive all relevant study information and actively declare their consent to participate in the study.

Other: questionnaire

Questionnaires and interviews were primarily used as assessment and introspection tools to collect data on study participants' experiences, perceptions, and behaviors. Their purpose was to facilitate measurement and reflection rather than to deliver an intervention. However, it is acknowledged that participation in questionnaires and interviews may have had unintended interventional effects. Specifically, the process of answering questions and reflecting on personal experiences can increase participants' self-awareness, prompt critical reflection, and potentially influence subsequent attitudes or behaviors.
