Working adults’ well‐being: An online self‐help goal‐based intervention

: An online self-help goal-setting and planning (GAP) intervention to improve working adults' well-being was tested using a longitudinal, randomized crossover design. The study sought to (1) test the effectiveness of the intervention relative to wait-list controls; and (2) test the stability of effects over a 3-month follow-up period. Participants were recruited from the UK Civil Service and were randomized to either a GAP intervention or a wait-list control condition. Wait-list participants then crossed-over to receive GAP. Relative to wait-list controls (N = 149), GAP participants (N = 158) reported significantly higher levels of positive affect (PA) and flourishing, but similar levels of negative affect (NA) and life satisfaction immediately after the intervention. Longitudinal data were analysed for the whole sample (N = 307). Compared to the start of the intervention, participants reported an increase in PA and flourishing directly after the intervention and 3 months later. NA and life satisfaction showed no change by the end of the intervention, but had improved by 3-month follow-up. Completing more modules predicted post-intervention improvements in well-being, accounting for pre-intervention well-being levels. The online self-help format allowed the intervention to be offered with minimal therapeutic support, enabling convenient access by a large group of employees. The study provides an example of a successful adaptation of a clinically proven well-being intervention to make it accessible to working adults. Practitioner points: Well-being interventions proven in clinical settings can be effectively adapted for use in workplace settings with only minor alterations.Brief, online self-help interventions can improve working adults' well-being.Goal-based interventions can improve working adults' well-being when focused towards goals that are aligned with personal values and have been chosen by the individual.
