Intention-Behavior Gaps in HIV Care

Last week at the bi-annual Ryan White Program Conference on HIV Care and Treatment, HIV care providers from across the country heard from the U.S. Secretary for Health and Human Services (DHHS), the head of the Health Resources and Services Administration (HRSA), and the head of the National Institute for Allergy and Infectious Diseases at NIH. These experts highlighted a central fact of the HIV epidemic, which is that it has for the past 20 years been as much a result of gaps between intention and behavior as it has been a medical crisis. The HIV treatment cascade shown here illustrates the patient behaviors needed to successfully manage this chronic disease. First, people at risk for HIV can avoid infection through appropriate prevention behaviors, like using condoms or taking pre-exposure prophylaxis (PrEP) medications. Once people are infected with HIV, they need to be tested in order to initate treatment. Then they must be linked to the care system, a barrier for younger people who may never have been involved with routine health care for a chronic condition. Once engaged in care, they must remain in care over time, and in order to gain the benefits of treatment they must stay adherent to medication. Each of these steps in the treatment cascade is one where patients' intentions may not match their behaviors, resulting in unnecessary health problems, gaps in care, or even treatment failure. Successfully supporting patients with each of these behaviors also requires health care practitioners to change behaviors, such as always testing for HIV or following up intensively when patients miss an appointment. Behavior change is a key to successful treatment in HIV and other chronic diseases.

Self-Determination Theory Through the Lens of Two Minds

Self-determination theory (SDT) is a framework for understanding human motivation. It gained a great deal of popularity as a possible explanation for the effects of motivational interviewing (MI), although MI's primary creator William Miller has said that his understanding of MI is atheoretical . It is certainly the case that MI came about long before SDT was used to explain it. And it's also true that SDT was an established model with its own body of research before it was ever linked to MI. But Stephen Rollnick, Miller's co-author in his most important works on MI, has specifically said that he considers SDT to provide the theoretical explanation for MI's success. Deci and Ryan (2000) propose six "mini-theories" or propositions that together make up SDT: 1. intrinsic motivation is a strong predictor of behavior, and is related to feelings of competence and autonomy. The intrinsic/extrinsic motivation distinction is an old one in psychology, reflecting ...

What Years of Anxiety Taught Me About Balancing Two Minds

Guest post by Dr. Britt Ritchie, DNP, PMHNP-BC First, a huge thank-you to Dr. Paul Cook for inviting me to contribute here. Paul was my Division Chair when I worked at the University of Colorado (CU) as an assistant professor. During that time, he saw me at one of my most vulnerable points—grappling with anxiety so intense it almost made me abruptly quit my job. I knew it was social anxiety—the kind of fear marked by an overwhelming sense of being judged, embarrassed, or humiliated in front of others—but knowing the label didn’t make it any easier to manage in the moment. Because of that shared history, it feels especially fitting to write about my experience lecturing during my time at CU through the lens of Paul’s Two Minds Theory. I can still picture the lecture hall—the rows of students, the humming projector, the fluorescent lights that were both too hot and too bright. On paper, I was prepared. I had spent hours rehearsing, editing slides, and reviewing notes. ...

New Article Finds Different Effects of Protective versus Adverse Childhood Events

In a new article , my former nursing honors student Linda Driscoll Powers wrote about the measurement properties of a survey called PACES -- standing for Positive and Adverse Childhood Experiences Survey -- developed by Dr. Laurie Leitch. The instrument combines items from the widely used ACEs (Adverse Childhood Experiences) measure with a set of protective factors such as having a supportive family, having a positive relationship with an adult outside the family, or belonging to social groups like a team or a church. ACEs items have been found to predict a variety of health outcomes in adulthood , either directly or by way of social support , but positive childhood experiences are under-studied . Besides having satisfactory psychometric properties (a stable factor structure, good internal consistency reliability, no evidence of response bias), the PACES items split cleanly into two independent subscales, one measuring positive experiences and the other measuring negative ones. ...
