BACKGROUND The rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the current coronavirus disease 2019 (COVID-19) outbreak, has led to strict social distancing and social isolation recommendations from the World Health Organization (1). As the elderly are most susceptible to critical illness and fatality due to infection with SARS-CoV-2, they have also been subjected to the most stringent social isolation guidelines in Canada as an attempt to prevent death in this population (1,2). While these public health measures are necessary to prevent the spread of SARS-CoV-2 among our vulnerable geriatric populations and to protect our over-burdened healthcare systems, social isolation has had a detrimental impact on the mental health of this population and has been deemed a mental health crisis (1,3) The aim of this study is to assess the feasibility of delivering The Student-Senior Isolation Prevention Partnership (SSIPP) in London, Canada, as compared to an active control, Problem Solving Therapy (PST), as well as a wait list control (WLC). Such a study would also allow to collect effect size estimates on the efficacy of SSIPP on self-rated depression, anxiety, and resilience among community-dwelling seniors. As SSIPP is more accessible and more readily available than PST, we aim to determine if SSIPP is as effective as the structured psychotherapy intervention PST at achieving these outcomes. Data from this study will help inform the design of a future large, multi-center RCT. OBJECTIVES Objective 1: To determine if it is feasible to conduct an RCT of telephone SSIPP in comparison to PST delivered to community-dwelling seniors during the current constraints imposed by COVID-19 and the need for telephone delivery of these services. Objective 2: To determine the extent of change in self-rated depression, anxiety, and resilience measures in a telephone delivered SSIPP as compared to telephone delivered PST and wait list control among community dwelling seniors. HYPOTHESES Hypothesis 1: It will be feasible to conduct an RCT of telephone SSIPP in comparison to telephone PST and a wait list control, under the current constraints imposed by COVID-19 and the need for telephone delivery of these services. Hypothesis 2: It will be possible to collect effect size estimates of SSIPP compared to PST and a wait list control on symptoms of depression, anxiety and resilience in community dwelling seniors. STUDY DESIGN This study will be single blind randomized, controlled trial comparing 12-week telephone delivered SSIPP and PST in a total of 45 participants, randomized in a 1:1:1 ratio to one of three groups. The three study groups that participants could be randomized to, include SSIPP, PST, or a waitlist control (WLC). The WLC participants will self-select participation in either SSIPP or PST at the end of the 12-week waiting period. They will not complete study assessments following week 12. This study will plan to enroll n=45 with 15 participants randomized to each of the three groups. Participants will be asked to complete brief, paper surveys, with a return envelope attached, to mail to the Division of Geriatric Psychiatry, at weeks 0 and 12 of the study. The option of completing surveys online through REDCap, an electronic data capture system offered by Lawson Health Research Institute, will be available to participants comfortable with this method of survey administration. REDCap will be used to achieve randomization and its concealment. Statistical analysts will be blinded to group allocation during data analysis. RECRUITMENT Participants will include community-dwelling seniors (n=45) recruited from the Division of Geriatric Psychiatry at Parkwood Institute and from the Geriatric Mental Health Program at London Health Sciences Center, both located in London, Ontario. Participants to these two programs receive referrals from family doctors serving the city of London and surrounding Middlesex county. The study will recruit via existing relationships and referrals established by the study PI. STATISTICAL ANALYSIS PLAN Primary outcome measures will be calculated using rates, percentages and costs. For exploratory purposes, the secondary outcome measures will be subject to the following analyses. A Multivariate Analysis of Variance (MANOVA) will be conducted to detect differences between the two interventions, i.e. SSIPP and PST as the independent variables and scores on GAD-7, PHQ-9, and CD-RISC-10 scale as the dependent variables. Multivariate F value (Wilks' ? or Hotelling's trace or Pillai's trace) will be used with a statistical significance set at p < 0.05. Demographic measures will be described using either calculations of means or percentage as required. Contingent on final sample size, either the Kolmogorov-Smirnov or the Shapiro-Wilk test will be used to assess normality of the data. The Expectation-Maximization (EM) algorithm will be used to account for missing data. Analysis will first be carried out using an Intent to Treat (ITT) approach, followed by per protocol (PP) analyses for the participants who completed the study only. The differences in anxiety, depression, and resiliency outcomes between the groups at week 0 and week 12 will be analyzed using a repeated MANOVA test, in both ITT and PP analysis groups.
