Brief digital interventions to support the psychological well-being of NHS staff during the COVID-19 pandemic: a three-arm pilot randomised controlled trial
ABSTRACT
Background:
Health and social care staff are at high risk of experiencing adverse mental health outcomes during the COVID-19 pandemic. Hence, there is a need to prioritize and identify ways to effectively support their psychological wellbeing. Compared to traditional psychological interventions, digital psychological interventions are cost effective treatment options that allow for large-scale dissemination and transcend social distancing, overcome rurality, and minimize clinician time.
Objective:
This study reports outcomes of a CONSORT-compliant parallel-arm pilot randomised controlled trial (RCT) examining the potential usefulness of an existing and a novel digital psychological intervention aimed at supporting psychological health among NHS staff working through the COVID-19 pandemic.
Methods:
NHS Highland (NHSH) frontline staff volunteers (N = 169) were randomly assigned to the newly developed NHSH Staff Wellbeing Project (NHSWBP), an established digital intervention (My Possible Self; MPS), or to a waitlist (WL) condition for four weeks. Attempts were made to blind participants to which digital intervention they were allocated. The interventions were fully automated, without any human input or guidance. We measured five self-reported psychological outcomes over three time points: before (baseline), middle (after 2 weeks) and after treatment (4 weeks). The primary outcomes were anxiety (GAD-7), depression (PHQ-9) and mental well-being (Warwick-Edinburgh Mental Well-being Scale). The secondary outcomes included mental toughness (Mental Toughness Index) and gratitude (the Gratitude Questionnaire).
Results:
Retention rates at middle and post-intervention were 77% (n = 130) and 63.3% (n = 107), respectively. At post-intervention, small differences were noted between the WL condition and the two treatment conditions on anxiety (vs. MPS: d = .07, 95% CI: -.20, .33; vs. NHSWBP: d = .06, 95% CI: -.19, .31), depression (vs. MPS: d = .37, 95% CI: .07, .66; vs. NHSWBP: d = .18, 95% CI: -.11, .46), and mental well-being (vs. MPS: d = -.04, 95% CI: -.62, -.08; vs. NHSWBP: d = -.15, 95% CI: -.41, .10). A similar pattern of between-group differences was found for the secondary outcomes. The NHSWBP group generally had larger within group effects than the other groups and displayed a greater rate of change compared to the other conditions on all outcomes, except for gratitude, where the rate of change was greatest for the MPS group.
Conclusions:
Conclusions:
Our analyses provided encouraging results for the use of brief digital psychological interventions in improving psychological well-being among health and social care workers. Future multi-site RCTs, with power to reliably detect differences, are needed to determine the efficacy of contextualised interventions relative to existing digital treatments.
