Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention was a vitality training employing scientifically-tested behaviour-change techniques. The intervention consisted of five two-hour group sessions that were performed in-house, on the organisations’ premises, which were held fortnightly over a nine-week period. A maximum of 12 participants could participate in a group session. The sessions included the following topics: 1. Personal energy balance analysis; 2. Physical and mental energy; 3. Working from qualities, values, and goals; 4. Personal vitality strategy; and 5. Evaluation and maintenance. The vitality training employed a specially designed ‘method’, which required that participants worked through assignments employing evidence-based behaviour-change techniques, including self-persuasion, implementation intentions, and self-efficacy techniques. This approach allowed participants to identify their own areas of concern, to set a limited number of personally relevant and meaningful goals, and to develop personalised strategies for change. The intervention was delivered by the (independent) developer of the training, who holds a PhD in clinical psychology and works as a researcher, university lecturer, and vitality trainer. Session content was delivered via workbooks; that is, participants completed assignments in their workbooks individually, following instructions from the trainer, and then a short group discussion took place after each assignment. Halfway through each 2-hour session there was a short 10-minute break. Adherence to the intervention method was controlled for, across sessions and participant groups, using a checklist, which was reviewed following each session. During the maintenance phase, the intervention group was not required to complete any activities nor were they contacted by the trainer. The duration of the maintenance phase was approximately 3 months after the completion of the final group session.

Comparator / control treatment
The comparator group was a no-treatment / wait-list control treatment.
The intervention group commenced the vitality training during Phase 1 and the control group was put on a waiting list for the training during this time (i.e., the wait-list control period was 9 weeks). During Phase 2, the control group completed the training and the intervention group was on a maintenance phase.

Outcomes
Primary outcome [1] 332419 0
Energy: Three items designed specifically for this study established participants’ subjective energy levels, which assessed the extent to which participants reported feeling i) energetic, ii) physically fit, and iii) mentally fit. Responses were made using visual analogue scales ranging from 0 to 100 (never to always). 'Energy’ was a mean of these three items. All measures were assessed in Dutch.
Timepoint [1] 332419 0
Baseline, post-intervention (primary timepoint), and follow-up.
Baseline data were collected up to two weeks prior to the commencement of the training. Post-intervention data was collected up to two weeks following the completion of the training. Follow-up was approximately 3-months following the completion of training for the intervention group (this was associated with the completion of the training for the wait-list control group).
Primary outcome [2] 332420 0
Stress: Two items designed specifically for this study established participants’ subjective stress levels, which assessed the extent to which participants reported feeling i) stressed and ii) overloaded. Responses were made using visual analogue scales ranging from 0 to 100 (never to always). 'Stress' was a mean of these two items. All measures were assessed in Dutch.

Secondary outcome [1] 413442 0
Daily life satisfaction: Four items designed specifically for this study established participants’ subjective daily life satisfaction, which assessed the extent to which participants reported being i) satisfied with their daily life, ii) paying attention to the activities in their daily life, as well as being iii) motivated towards and iv) inspired by the activities in their daily life. Responses were made using visual analogue scales ranging from 0 to 100 (never to always). ‘Daily life satisfaction’ was a mean of these four items. All measures were assessed in Dutch.

Responses were made using visual analogue scales ranging from 0 to 100 (never to always). ‘Work capacity’ was a mean of these six items. All measures were assessed in Dutch.
Timepoint [2] 413443 0
Baseline, post-intervention, and follow-up.
Baseline data were collected up to two weeks prior to the commencement of the training. Post-intervention data was collected up to two weeks following the completion of the training. Follow-up was approximately 3-months following the completion of training for the intervention group (this was associated with the completion of the training for the wait-list control group).
Secondary outcome [3] 413546 0
Self-efficacy was included as a possible process measure: Five items designed specifically for this study established participants’ subjective ability to manage their work-life balance, which assessed the extent to which participants reported an ability to i) change their work-life balance, ii) influence on having a good work-life balance, iii) make choices, and iv) set boundaries regarding their work-life balance, and the extent to which v) their goals regarding their work-life balance are achievable. Responses were made using visual analogue scales ranging from 0 to 100 (never to always). ‘Self-efficacy’ was a mean of these five items. All measures were assessed in Dutch.

Statistical methods / analysis
The sample size was determined on a pragmatic basis, including employees across participating organisations who elected to complete the training and participate in the study.

The effects of the intervention on quantitative outcomes were examined using a mixed MANOVA and univariate ANOVA procedures. Mediation effects were explored using bootstrapping procedures.

Summary
Brief summary
Vitality has important implications for individuals’ personal lives as well as for their working lives and is positively related to one’s physical and mental health, wellbeing, and life satisfaction. At work, vitality is related to thriving, work engagement, and reduced burnout levels. Therefore, improving employee vitality has implications for individuals and for the organisations for which they work. The purpose of this project was to assess the effects of a nine-week vitality training that employed behaviour-change techniques, including whether any observed effects were maintained three months following training. To evaluate the training, employees were randomly assigned to either a 'training' group or a 'wait-list' control group, and reported energy, stress, daily life satisfaction, work capacity, and self-efficacy to manage one’s work-life balance were assessed prior to, immediately after, and three months following the training.
