Salutogenic Healthy Ageing Programme Embracement (SHAPE)- an upstream health resource intervention for older adults living alone and with their spouses only: complex intervention development and pilot randomized controlled trial

Background In view of age-related health concerns and resource vulnerabilities challenging older adults to age in place, upstream health resource interventions can inform older adults about the availability, accessibility, and utility of resources and equip them with better coping behaviours to maintain health and independence. This paper described the development process and evaluated the feasibility of an upstream health resource intervention, titled Salutogenic Healthy Ageing Programme Embracement (SHAPE), for older adults living alone or with spouses only. Methods A pilot randomised controlled trial design was adopted. SHAPE was designed to equip older adults with resource information and personal conviction to cope with stressors of healthy aging. This 12-week intervention comprised 12 weekly structured group sessions, at least two individual home visits and a resource book. Both the intervention and control groups received usual care provided in the community. Feasibility of SHAPE intervention was evaluated using recruitment rate, intervention adherence, data collection completion rate, satisfaction survey and post-intervention interview. Outcome measures (sense of coherence, health-promoting lifestyle behaviours, quality of life, self-efficacy, and self-rated health) were assessed at baseline and post-intervention. Paired t-tests were used to examine within-group changes in outcome measures. Content analysis was used to analysed qualitative data. Results Thirty-four participants were recruited and randomised. While recruitment rate was low (8.9%), intervention adherence (93.75%) and data collection completion (100%) were high. Participants expressed high satisfaction towards SHAPE intervention and found it useful. Participants experienced mindset growth towards personal and ageing experiences, and they were more proactive in adopting healthful behaviours. Although the programme was tailored according to needs of older adults, it required refinement. Intention-to-treat analysis showed significant increase in overall health-promoting lifestyle behaviours, health responsibility, physical activity, spiritual growth, and stress management among intervention participants. However, they reported a significant drop in autonomy post-intervention. Conclusion Findings of this pilot trial suggested that with protocol modifications, SHAPE can be a feasible and beneficial health resource intervention for older adults. Modifications on recruitment strategies, eligibility criteria, selection of outcome measures, training of resource facilitators and strong collaboration bonds with community partners would be needed to increase feasibility robustness and scientific rigor of this complex intervention.
