Online acceptance and commitment therapy as treatment for loneliness among older adults: Report of a pilot study

Loneliness has been linked to cognitive decline, cardiovascular risk, and risk of mortality among older adults. Creative approaches are needed to increase access for older adults to evidence-based intervention programs. One possible approach is acceptance and commitment therapy (ACT). The aim of this study was to pilot test a novel ACT-based online intervention to decrease loneliness in older adults living in the community.

A self-paced online ACT program consisting of eight interactive modules designed to teach participants skills to address common contributors to loneliness was evaluated. It was delivered to a sample of 529 men and women, aged 65 or over, who were assessed pre-intervention, postintervention, and at a one-month follow-up, with a short 10-item version of the UCLA Loneliness Scale.

For participants who completed all eight modules of the intervention, average levels of loneliness significantly decreased from pre- to posttreatment, b = -0.013, t (385) = -4.69, p < 0.001 (Cohen's d = 0.30). The improvement in loneliness was maintained at the one-month follow-up assessment. These improvements were particularly robust for individuals who were lonely at outset (Cohen's d = 0.73). The change in loneliness among these individuals was significantly greater than that observed in members of a "hold-out" group of lonely individuals that did not participate in the intervention (Cohen's d = 0.24).

This pilot investigation suggests the feasibility of this program for decreasing loneliness in older adults. Future controlled investigations with long-term follow-up assessments are needed to confirm the effectiveness and sustained benefits of the program.
