The Resilience Hub was established to support people in need of psychological/psychosocial support following the 2017 Manchester Arena terrorist attack.

To use mental health screening measures over 3 years following the Arena event to examine the variation in symptoms reported by adults registered with the Hub, and whether this was associated with treatment access characteristics.

Adults engaging with Hub services were separated into eight cohorts depending on when they registered post-incident. Participants completed screening measures for symptoms of trauma, depression, generalised anxiety and work/social functioning. Baseline and follow-up scores over 3 years were compared among the eight admission groups. All types of appointment were recorded in terms of the number of minutes of clinical ‘contact time’ involved, to explore associations with time taken to register.

Overall, baseline screening scores increased as time to register post-event increased. Over the 3 years of follow-up, a decrease in scores was observed for all 4 screening measures, indicating improvement in mental well-being. Those taking longer to register had higher follow-up scores. However, they showed a slightly stronger decrease in average change of score per follow-up month. Mean contact time per month was greater (apart from the 18-months admission group) in individuals delaying registration. Increased contact time was associated with decreased follow-up screening scores for depression and anxiety.

People who registered earlier were less symptomatic, suggesting there may be a potential beneficial impact of early engagement with support services following traumatic events. All who registered showed improvement in symptoms, including those delaying registration, with increased contact time being beneficial. This reinforces the benefits of encouraging early and sustained engagement with services as soon as possible post-incident.

The Resilience Hub was established to coordinate mental health and psychosocial support for anyone affected by the 2017 Manchester Arena terrorist attack.

To use the Hub’s mental health screening data to examine the variation in symptoms reported by children and young persons (CYP) and their parent/guardian and explore any association with time delay in post-event registration or parental distress.

CYP engaging with Hub services were separated into eight ‘admission’ groups depending on when they registered post-incident. CYP were screened for trauma, depression, and generalised and separation anxiety. Parents/guardians also completed screening measures for their own and their child’s anxiety. Baseline and follow-up scores were compared between admission groups. Parental and CYP assessments of the CYP’s anxiety score was compared with the measure of parental distress.

Almost half of CYP registered in the first 3 months of service launch, with numbers of new registrations falling during each subsequent screening cycle. Generally, there was an increase in baseline screening scores as Hub registration time increased. The Children’s Impact of Event scale score decreased by 0.11 (95% CI: −0.17, −0.05) per month, but the score for depression increased by 0.06 (95% CI: 0.03, 0.10). Longitudinal patterns in anxiety and separation were difficult to discern. Screening scores of CYP registering later reduced at a faster rate than those of the first registrants. Higher levels of parental mental distress were correlated with increased anxiety scores assigned to the CYP in relation to the anxiety score reported by the CYP themselves.

CYP who registered earlier were less symptomatic, although those registering later did show increased improvement in their symptoms, indicating that the Hub was beneficial. Parental well-being was associated with child mental distress, indicating that shared family trauma should be considered when planning care.
