Autobiographical Time Travel to Alleviate Loneliness in Older Adults

Unlocking Resilience: Autobiographical Time Travel as an Antidote to Loneliness in Older Adults

The goal of this clinical trial is to examine whether updating fundamental beliefs about self, others and the world using a mental time-travel group program can reduce loneliness and improve well-being in older adults when combined with multimodal social engagement opportunities. Over the span of eight sessions, participants within the experimental group will be guided to complete autobiographical simulations grounded in therapeutic techniques including reminiscence, imagery rescripting and positive future thinking. Participants within the active control group will be instructed to continue with their usual social group activities.

Older adults (≥65 years) from the Kimel Family Centre registry will be recruited based on a pre-specified score of loneliness. Recruitment will occur on a rolling basis through email and telephone contact, in-person booths, and information sessions. Kimel members who express interest in participating will then be emailed to schedule a time to be screened for eligibility via telephone.

Prior to the telephone screening, consent forms will be sent via email for participants to review. The details of the study will be explained at the beginning of a telephone screening process. Participants will be given the opportunity to ask questions and to indicate whether they wish to continue, whereupon the screening questions will be administered to those who agree. Those who meet the eligibility criteria and provide informed consent will be scheduled for randomization into one of the two groups. Randomization will be computer-generated, stratified by baseline loneliness severity, number of other social groups taken at Kimel Family Centre, sex and gender.

Participants will be randomly assigned to either: (1) Experimental condition: mental time travel protocol (reminiscence induction + imagery rescripting + positive prospection) or (2) a time-matched control condition: Kimel Centre group activities (see Arms and Interventions). Both groups will be encouraged to continue engaging with existing Kimel Centre programming throughout the study period.

Both groups will complete the scheduled outcome assessments at baseline, 1-month post-baseline, 3-month follow-up, and 6-month follow-up. The experimental group will complete additional assessments throughout the experimental sessions (see Outcome measures).

After completion of the main study, participants assigned to the time-matched control may be offered an opportunity to receive the structured experimental protocol, provided that the study remains active and the investigators determine that offering the protocol is appropriate.

Inclusion Criteria:

• Age ≥65
• Elevated loneliness based on a pre-specified cutoff of 44 on the UCLA version 3 Loneliness Scale (Russell, 1997)
• Capacity to provide informed consent
• Ability to participate in group sessions twice a week for four weeks

Exclusion Criteria:

• A diagnosis of dementia, mild cognitive impairment, stroke, other neurodegenerative disorders, schizophrenia, bipolar disorder, personality disorders
• Any condition that would limit participants' capacity to benefit from or safely and comfortably complete the protocol. Given the nature of the protocol, which involves autobiographical memory recall in a group setting, individuals with a history of trauma-related diagnoses (e.g., PTSD or acute stress disorder) and/or those who score in the severe or extremely severe range on any of the depression (≥ 21), anxiety (≥ 15), or stress (≥ 26) subscales of the DASS-21, will be excluded in order to minimize the risk of significant distress during sessions
• Participants who are unable to complete short questionnaires at each session and online at follow-up will be excluded
