The Effectiveness of a Brief Telehealth and Smartphone Intervention for College Students Receiving Traditional Therapy: Longitudinal Study Using Ecological Momentary Assessment Data

The Effects of a Single-Session Virtual Rumination Intervention to Enhance Cognitive Functioning in Veterans With Subjective Cognitive Symptoms: Multimethod Pilot Study

BACKGROUND

Subjective cognitive concerns (SCCs) entail perceived difficulties in thinking or memory, often reported without substantial objective evidence of cognitive impairment. These concerns are prevalent among individuals with a history of brain injuries, neurological conditions, or chronic illnesses, contributing to both psychological distress and functional limitations. They are increasingly considered to be a risk factor for future objective decline. A considerable number of individuals reporting SCCs also exhibit mental health symptoms, such as a history of trauma, depression, or anxiety. Interventions that address modifiable emotional and cognitive factors related to SCC could improve functioning and quality of life. Therefore, the use of emotion regulation strategies, especially those directed at minimizing rumination, could serve as a promising focus for interventions aimed at mitigating subjective cognitive concerns in veteran populations.

OBJECTIVE

This pilot study explored the feasibility, acceptability, and preliminary efficacy of a brief, 1-session emotion regulation intervention called "Worry Less, Remember More." The Worry Less, Remember More intervention was designed to reduce rumination and improve subjective cognitive functioning in veterans with subjective cognitive changes (N=15).

METHODS

We randomized 15 veterans to either the active telehealth condition or waitlist control and completed the intervention. Participants were aged between 31 and 67 (mean 49.5, SD 10.1) years, and the sample was primarily male (12/15, 83%) and White (10/15, 67%). The most common diagnoses were posttraumatic stress disorder and depression. Following the intervention, veteran input was sought through semistructured interviews with a subset of 12 participants, examining feasibility, acceptability, and perceived efficacy. Preliminary efficacy was also measured using pre- and postintervention self-report measures.

RESULTS

Veterans reported that this intervention was acceptable, with 92% (11/12) of the sample reporting that they benefited from the intervention and would recommend the intervention to others with similar difficulties. Semistructured interviews revealed difficulties with feasibility, including problems with the remote consenting process, forgetting appointments, and needing additional strategies to remember to consistently use the interventions. The intervention improved self-reported cognitive symptoms on quantitative measures but did not improve self-reported rumination.

CONCLUSIONS

This pilot study establishes the preliminary feasibility, acceptability, and efficacy of the Worry Less, Remember More intervention for veterans with subjective cognitive symptoms. Future iterations of the intervention may benefit from simplifying the electronic consent process, providing reminders for appointments, and incorporating compensatory cognitive strategies to assist with using the telehealth system, as well as applying the strategies learned in the intervention. While future research is needed with larger samples, including nonveteran populations, the intervention may also be a useful clinical tool to bridge care between neuropsychology clinics and mental health treatment.
