Results Summary

What was the research about?

Serious worry is a problem for up to 30 percent of adults age 55 or older. Serious worry is worry about everyday problems that happens often and is hard to control. It may make people feel restless, tired, or tense. Serious worry can be part of another anxiety condition or a problem on its own.

Compared with other older adults, those adults with serious worry are more likely to have poor physical health, and they often have depression and sleep problems. They are also more likely to have trouble thinking clearly. Doctors don’t always recognize or treat serious worry, especially in older adults who live in neighborhoods with few resources. Compared with white adults, African American adults are less likely to be diagnosed and treated for serious worry.

In this study, the research team compared two treatments for older adults who had serious worry. People received one of two treatments from social workers or community health workers, or CHWs. CHWs are trained to teach about health and link people in their community with health and social services.

  • In one approach, called Calmer Life, people received up to 12 training sessions for three months to learn healthy ways of thinking and acting. They also learned how to get help with needs such as food or housing. Social workers and CHWs matched trainings to each adult’s needs. They included religion or spirituality if requested. The trainers followed up by phone every month for another three months.
  • In the other approach, enhanced community care, social workers and CHWs gave each person a customized list of food, housing, mental health, and other services. The social workers or CHWs also called clients every month or more often to offer support and check on symptoms.

What were the results?

Both treatments worked about the same. At the end of the study, people receiving either treatment had

  • Less worry
  • Less anxiety
  • Fewer symptoms of depression
  • Better sleep
  • More ability to do social activities
  • More ability to do daily activities despite disability
  • Better quality of life related to mental health

Physical health stayed the same with either treatment.

More people in Calmer Life than in enhanced community care had hospital stays during the second three months of the study. People in Calmer Life were more satisfied with their program six months after the study began than were adults who got enhanced community care. There was no difference at nine months.

Who was in the study?

The study included 148 adults, age 50 and older, with significant worry who lived in neighborhoods with few resources. Of these adults, 76 percent were African American, 17 percent were white, 5 percent were Hispanic, and 2 percent were other races. The average age was 67, and 82 percent were women.

What did the research team do?

The research team assigned the older adults to one of the two groups by chance. At the start of the study and six and nine months later, the team surveyed the adults about worry, anxiety, depression, and other symptoms.

Clients, counselors, and managers from social service and faith-based agencies helped plan, design, and conduct the study.

What were the limits of the study?

The study compared two treatments to each other, but not to usual care. The research team can’t be sure the changes in the study are a result of those treatments.

Future research could look at whether these treatments could be delivered to groups instead of one-on-one. Studies could also look at whether the treatments work for people who speak Spanish.

How can people use the results?

Social service agencies or health systems can consider using either Calmer Life or enhanced community care or both approaches to help older adults with serious worry.

Peer-Review Summary

Peer review of PCORI-funded research helps make sure the report presents complete, balanced, and useful information about the research. It also assesses how the project addressed PCORI’s Methodology Standards. During peer review, experts read a draft report of the research and provide comments about the report. These experts may include a scientist focused on the research topic, a specialist in research methods, a patient or caregiver, and a healthcare professional. These reviewers cannot have conflicts of interest with the study.

The peer reviewers point out where the draft report may need revision. For example, they may suggest ways to improve descriptions of the conduct of the study or to clarify the connection between results and conclusions. Sometimes, awardees revise their draft reports twice or more to address all of the reviewers’ comments. 

Peer reviewers commented, and the researchers made changes or provided responses. Those comments and responses included the following:

  • Overall, reviewers’ comments were positive about the quality of this final report.
  • Reviewers asked for additional information on subgroup analyses, particularly related to race and ethnicity. The researchers acknowledged limitations in being able to conduct these analyses because of the underrepresentation of minority status groups other than for African Americans in the geographic area of the study. The report does present the researchers’ analyses of outcome differences between African-American and white study participants.
  • Reviewers asked the researchers to speculate on why attrition was higher than expected in this study. The researchers noted that higher attrition happened after enrollment but before the baseline assessment, while attrition postbaseline was as expected.

Health Conditions Health Conditions These are the broad terms we use to categorize our funded research studies; specific diseases or conditions are included within the appropriate larger category. Note: not all of our funded projects focus on a single disease or condition; some touch on multiple diseases or conditions, research methods, or broader health system interventions. Such projects won’t be listed by a primary disease/condition and so won’t appear if you use this filter tool to find them. View Glossary
Populations Populations PCORI is interested in research that seeks to better understand how different clinical and health system options work for different people. These populations are frequently studied in our portfolio or identified as being of interest by our stakeholders. View Glossary
Intervention Strategy Intervention Strategies PCORI funds comparative clinical effectiveness research (CER) studies that compare two or more options or approaches to health care, or that compare different ways of delivering or receiving care. View Glossary
