NCT04719351

Brief Summary

The current pandemic highlighted an urgent need for early interventions to mitigate the psychological effects of extreme work demands that healthcare workers currently experience. This project aims at developing a data driven monitoring system to efficiently track work-related stress reactions over time. The system will also include a self-awareness intervention grounded on evidence-based strategies to improve workers' recovery. The solution will be delivered through a mobile application for a rapid implementation among healthcare workers and related professions. The mobile application will be developed through an initial analysis of pilot data, a factorial experiment and a user-experience analysis. Qualitative user experience data will also be used to validate the functionality of the monitoring system. The solution developed in this project will be easily scalable to related occupations, for example workers at elderly homes and social workers. After the pandemic, it can also be used as a preventive intervention for workers who are at risk of burnout and as a support for patients returning to work after treatment for common mental disorders.

Outcome Measures

Primary Outcomes (6)

  • Burnout symptoms immediate effect

    Burnout is measured using Oldenburg Burnout Inventory (Olbi), an instrument designed to measure exhaustion and disengagement: (Demerouti, E, Bakker, A.B, Vardakou, I, \& Kantas, A. \[2003\]. The convergent validity of two burnout instruments : a multitrait-multimethod analysis. European Journal of Psychological Assessment : Official Organ of the European Association of Psychological Assessment, 19(1), 12-23. https://doi.org/10.1027//1015-5759.19.1.12) The full Olbi scale consists of twelve items, and this study uses a subset of seven items. The study uses a Swedish version: Gustavsson, J. P., Hallsten, L., \& Rudman, A. (2010). Early career burnout among nurses: modelling a hypothesized process using an item response approach. International Journal of Nursing Studies, 47(7), 864-875. The items are scored on a 4-point Likert scale (1 = Not at all, 4 = Exactly).

    A month after completed intervention

  • Emotional exhaustion immediate effect

    Emotional exhaustion is measured using Shirom-Melamed Burnout questionnaire (SMBQ), a 22-item instrument designed to assess burnout: Shirom, A., \& Melamed, S. (2006). A comparison of the construct validity of two burnout measures in two groups of professionals. International journal of stress management, 13(2), 176. This study uses the SMBQ-6, a subset of six items, specifically measuring emotional exhaustion. A Swedish version is used for this study: Lundgren-Nilsson, Å., Jonsdottir, I. H., Pallant, J., \& Ahlborg, G. (2012). Internal construct validity of the Shirom-Melamed Burnout questionnaire (SMBQ). BMC public health, 12(1), 1. Items are scored on a 7-point Likert scale (1 = Very rarely, 7 = Very frequently).

  • Stress symptoms immediate effect

    Stress is measured using the Perceived Stress Scale (PSS), designed to measure "the degree to which situations in one´s life are appraised as stressful" (Cohen, S., Kamarck, T., \& Mermelstein, R. \[1983\]. A global measure of perceived stress. Journal of health and social behavior, 385-396). The original scale contains 14 items, and this study uses the PSS-10 version which contains 10 items. A Swedish translation of the scale is used: Nordin, M., \& Nordin, S. (2013). Psychometric evaluation and normative data of the Swedish version of the 10-item perceived stress scale. Scandinavian journal of psychology, 54(6), 502-507. The items are scored on a 5-point Likert scale (1 = Never, 5 = Very often).

Interventions

The mobile application has two main functionalities. First, it will remind the user to report in regular time periods on their mental health status (e.g., sleep disturbances, stress). The assessment is done daily for four weeks. Second, some completed assessments will be combined with a behavioral prompt i.e. short message encouraging the user to engage in one of the strategies that can help coping with stress at work, e.g. remember to take short breaks, exercise in daylight, summarize a day with a colleague after a finished shift.

Model Details: The factorial experimental trial will randomize participants to one of 32 experimental conditions which consist of any combination of the five components: 1) questions about positive emotions (yes/no), 2) questions about work environment (yes/no), 3) questions about controllability (yes/no), 4) questions with open answers (yes/no), and 5) behavioral prompts (yes/no). The purpose of this factorial experiment is to estimate the main effects of the five intervention components and interactions between the components.

Data Sharing

IPD Sharing
Will share

An anonymized subset of the data relevant for a particular publication (including metadata and code for the analyses conducted) will be registered on the OSF repository and provided with the DOI number. Neither qualitative data (i.e. answers to open questions) nor any personal data (i.e. gender, age, occupation) will be shared to ensure complete anonymity of the study participants. Data regarding each publication will become available already at the pre-print stage of each publication (i.e. manuscript submitted for publication), under the CC-BY license. Data will be stored in .csv format and will include raw data as well as data analysis files (analysis code). The data publication may be postponed and restricted in case a patent application will be submitted for a review.

Shared Documents
STUDY PROTOCOL, ANALYTIC CODE
Time Frame
Data will become available upon each scientific publication, at the preprint stage. Complete anonymized dataset will be shared no later than four years after initial data collection took place.
