Testing the Efficacy of a Web-Based Intervention for Loss and Bereavement in Later Life (AgE-health Study): Results From a Randomized Controlled Trial

Testing the Efficacy of a Web-Based Intervention for Loss and Bereavement in Later Life (AgE-health Study): Results From a Randomized Controlled Trial

On the basis of previous comparable trials using the PG-13 as primary outcome [26,28,52], a moderate effect size of Cohen d=0.5 was considered to power the trial. Given a significance level of α=.05 and a statistical power of 1–β=.8, the optimal sample size to detect a moderate between-group effect at 4-month follow-up was calculated to be 128 (n=64, 50% per group). Considering a dropout rate of 25% based on previous trials [53,54], an initial sample size of 170 participants at baseline was aimed for.

Feasibility, Acceptability, and Preliminary Outcomes of a Mobile Adaptation of a Relational Savoring Intervention to Prevent Loneliness in College Students: Mixed Methods Pilot Study

Day was the total number of days assessed, which enabled us to consider trends over time (154 d in total). The EMA number referred to the assessment for that day, which enabled us to consider trends over the day (5 assessments, later changed to 3, per day). Both survey day and EMA were included as a fixed effect (covariate) to account for change over the assessment as well as how much people’s loneliness and social connectedness may vary within a day.
