Change in study design was implemented and the study design no longer follows a pilot randomized controlled trial.

This study will test a telephone-based group intervention called "The CONNECT Program" which is designed for adults aged 65+ who are currently experiencing social isolation or loneliness, and symptoms of anxiety or depression. A pilot randomized controlled trial (RCT) will be conducted to evaluate The CONNECT Program using a clinical sample of adults 65+. The goals of this research include, (a) testing the feasibility of conducting a large-scale RCT using a clinical sample of adults 65+; (b) understanding the experiences of this clinical sample of adults 65+ in The CONNECT Program; and (c) investigating the preliminary effectiveness of this program with this sample. Participants (N=16) will be randomly assigned to either the waitlist or intervention group. Both groups will receive the intervention and share their experiences in The CONNECT Program. The waitlist group will receive the intervention after the waiting period. All participants will complete questionnaires before receiving the intervention, after receiving the intervention, and each week during the intervention. This study will provide us with insight regarding what this clinical sample of participants think of The CONNECT Program, how we can improve the program in the future in order to meet the needs of this group, what changes to the study design are needed in order to execute a large-scale randomized controlled trial in the future, and if this program shows preliminary effectiveness in this sample.

The population of adults aged 65+ in Canada is increasing (Statistics Canada, 2019). Some of the most common mental health and psychosocial problems experienced by adults aged 65+ include anxiety, depression, social isolation, and loneliness. The current research will test a telephone-based group intervention called "CONNECT" which is designed for adults aged 65+ who are currently experiencing social isolation or loneliness, and symptoms of anxiety or depression. CONNECT stands for: "Creating Opportunities to build social Networks, learn New skills to manage challenging emotions Enhance mindful awareness and acceptance of emotions, and increase self-Compassion, through Telephone-based group programming". A pilot randomized controlled trial will be conducted to evaluate The CONNECT Program using a clinical sample of adults 65+ recruited from Winnipeg and Brandon.

We will use a randomized design to pilot this intervention and assess the feasibility of implementing and testing this intervention with a clinical sample of adults 65+. Participants will be randomized 1:1 to one of two conditions (1 = intervention, 2 = waitlist). The quantitative data we collect will inform us about changes in self-reported symptoms on the primary and secondary outcome measures and it will reveal information about treatment satisfaction and how participants experienced each session. Additionally, the questionnaire that will be administered after each session and the post-CONNECT questionnaire will include open-ended questions where participants can expand on their answers about treatment satisfaction and their experiences in the program.

Within one week before the first CONNECT session, all participants will complete the baseline questionnaire and will then be randomized to one of two groups (1 = intervention, 2 = waitlist). One week after the baseline questionnaire is complete, participants in the intervention group will receive six weeks of CONNECT group therapy, and participants in the waitlist group will begin the waiting period. Within one week of the last CONNECT session, all participants will complete the post-CONNECT questionnaire. Participants receiving the intervention will also complete the Group Session Rating Scale (GSRS) after each session in order to monitor the participant progress from session to session and to evaluate the group-therapy alliance. Due to the exploratory nature of this pilot RCT, participants in the waitlist group will complete the baseline questionnaire again, they will receive the intervention and complete the GSRS each week, and they will complete post-CONNECT questionnaire one week after the last session. We plan to collect this data because we want to capture the experiences of the waitlist participants both when they are waiting for the intervention and when they receive the intervention. The purpose of including a waitlist group is to help determine if the current study procedures are acceptable. This will allow us to better understand potential issues such as participant dropout, and it will help us identify changes that should be made for a future RCT.

Inclusion Criteria:

• 65 years of age or older, currently living in Manitoba, self-reporting symptoms of social isolation and/or loneliness, and self-reporting symptoms of depression and/or anxiety.

Exclusion Criteria:

• Under 65 years of age, living outside of Manitoba, being unable to provide consent independently, deafness not corrected by hearing aids (hearing is needed as this is a telephone program), an absence of self-reported symptoms of anxiety or depression, an absence of symptoms of loneliness or social isolation, self-reporting suicidal ideation or suicidal behaviours that are current, substance use or substance dependence within the past six months, bipolar I or II, psychotic disorders, and major neurocognitive disorders. Another exclusion criteria would be an individual who does not have access to a telephone, or is not comfortable using the telephone for the purpose of The CONNECT Program or The research components (i.e., the questionnaires).

There is no plan to share this data.
