Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Emotional and social loneliness

    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.

    Asessed at baseline (T0), immediate after (T1), 3 months (T2), and 6 months (T3) post-intervention

  • Existential Loneliness

    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).

    Asessed at baseline (T0), immediate after (T1), 3 months (T2), and 6 months (T3) post-intervention

Secondary Outcomes (5)

  • Negative emotions

    Asessed at baseline (T0), immediate after (T1), 3 months (T2), and 6 months (T3) post-intervention.

  • Social connectedness

    Asessed at baseline (T0), immediate after (T1), 3 months (T2), and 6 months (T3) post-intervention

  • Meaning in life

    Asessed at baseline (T0), immediate after (T1), 3 months (T2), and 6 months (T3) post-intervention.

  • Nostalgia

    Asessed at baseline (T0), immediate after (T1), 3 months (T2), and 6 months (T3) post-intervention

  • Experiences and perceptions of older adults in intervention group

    Assessed within 1 day (T1) after the intervention

Study Arms (2)

Experimental: Nostalgia intervention

EXPERIMENTAL

In addition to usual community support services, participants in the intervention group will receive the face-to-face nostalgia intervention weekly for 5 weeks (each session lasting approximately 90 minutes), with each group consisting of 5-8 older adults.

Behavioral: Nostalgia intervention

Wait-list control

NO INTERVENTION

Participants in the wait-list control group will receive usual community support services provided by the community centres they belong to.

Interventions

Participants in the intervention group will receive the face-to-face nostalgia intervention weekly for 5 weeks (each session lasting approximately 90 minutes), with each group consisting of 5-8 older adults. The intervention consists of 5 sessions: Session 1 (understanding nostalgia and its benefits), Session 2-4 (music/ photos/ meaningful objects and nostalgia), Session 5 (reaffirming the benefits of nostalgia).

Experimental: Nostalgia intervention
