About this study

Official title: Positive Affect Regulation as Adjuvant to Integrative Therapies for Chronic Pain: Development of the LARKSPUR Clinic-Based Intervention

Chronic pain affects millions of Americans but integrative as well as conventional treatments fall short in terms of alleviating this pain. The investigators are testing a tailored online positive affect skills intervention through a high-quality, randomized controlled trial for people with chronic musculoskeletal pain. The proposed work holds promise as an effective, low cost, easily disseminated intervention to help people cope with chronic pain, decrease depression and distress that pose barriers to optimal adherence, and potentially boost the efficacy of integrative as well as conventional pain treatments.

Study groups in NCT03699553
Study groupRoleWhat they receive
InterventionExperimentalParticipants will receive the online LARKSPUR intervention which lasts about 5-6 weeks, receiving the positive emotions skills through the website, and logging on to the website for about 5-10 minutes each day for that period. Assessments will be taken at baseline, post-intervention (8 weeks after the baseline), and 12 weeks after baseline (1 month post intervention).

Questions about this trial

What is this clinical trial studying?

A study testing LARKSPUR; Online Positive Emotions Skills for Individuals with Chronic Musculoskeletal Pain in people with Chronic Pain and Musculoskeletal Pain, run by Northwestern University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Retention to the LARKSPUR Study from baseline to 8 weeks post baseline (time frame: 8 weeks; from baseline to 8 weeks post baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jan 2023.
