简要总结
The proposed study will utilise a two-arm, cluster-randomised, waitlist-controlled trial to (1) examine the effects of the nostalgia intervention on loneliness, negative emotions, social connectedness, meaning in life and nostalgia amongst community-dwelling older adults in Hong Kong; (2) investigate whether the effect of the nostalgia intervention on loneliness is mediated by improvements in negative emotions, social connectedness and meaning in life; and (3) explore the experiences and perceptions of older adults participating in the nostalgia interventions, focusing on their views regarding the impact of the intervention on their loneliness.
详细描述
A convenience sample of 294 older adults from six participating community centres, with 49 participants from each centre. Eligible older adults will be randomly assigned to either a waitlist control group (n = 147) or an intervention group (n = 147). Both groups will receive standard community support services, whilst the intervention group will also participate in five weekly face-to-face nostalgia sessions (approximately 90 min each) in a group format. Additionally, a purposive subsample of 30 participants from the intervention group will be invited for focus group interviews.
The primary outcome (loneliness) and secondary outcomes will be assessed at baseline (T0), immediately post-intervention (T1), 3 months post-intervention (T2) and 6 months post-intervention (T3) using validated questionnaires. The investigators will analyse the quantitative data using a generalised estimating equation model with intention-to-treat and path analyses. The qualitative data will be analysed using reflexive thematic analysis. The findings of this proposed study will inform healthcare professionals and policymakers, offering practical strategies to combat loneliness in this vulnerable group.

结局指标
主要结局
Emotional and social loneliness
时间窗: Asessed at baseline (T0), immediate after (T1), 3 months (T2), and 6 months (T3) post-intervention
The Chinese version of the De Jong Gierveld Loneliness Scale. This six-item scale scores range from 0 to 6, with higher score indicates higher level of loneliness. This scale demonstrates good internal consistency (Cronbach's α = 0.76) and inter-rater reliability (ICC = 0.98-1.00), as well as a strong correlation with direct assessments of loneliness.
Existential Loneliness
时间窗: Asessed at baseline (T0), immediate after (T1), 3 months (T2), and 6 months (T3) post-intervention
Existential Loneliness Questionnaire, which comprises 22 items focused on loneliness in social ties, loneliness in close relationships and the search for meaning in life. The scores range from 22 to 132, higher scores indicate higher level of existential loneliness. The questionnaire also demonstrates good internal consistency (Cronbach's α = 0.90).
