When young adults are asked to recall their drinking habits, their memories may not always match what actually happened in their daily lives, a new study suggests. People tend to remember major events, such as accidents or fights, but may forget more subjective experiences, such as cravings or changes in alcohol tolerance.
This disconnect between memory and reality can make it difficult for clinicians and researchers to fully understand the range of alcohol use disorder (AUD) symptoms that people are experiencing. The survey results are clinical psychology, Relying solely on memory can leave important gaps, suggesting that new assessment strategies are needed to get a clearer picture of what is really going on.
In this study, researchers found that real-time measurement of AUD symptoms provides more detailed insight into day-to-day experiences than traditional retrospective self-reports, which have long been the standard in both research and clinical settings.
“Some of the retrospective measures were highly correlated with day-to-day measures, while others were less correlated,” said Dani Kang, assistant professor of psychiatry at the University of Washington and lead author of the study.
This “means we’re missing half the picture,” added APS Fellow Kevin King, professor of psychology at the University of Washington and co-author of the study.
Retrospective self-report, which often asks people to reflect on their experiences over the past six months or year, is an important tool for screening and treatment. However, it falls short in terms of capturing how AUD symptoms unfold and fluctuate in everyday life.
“While we are conducting studies like this to understand the pathogenesis of AUD, we are conducting a completely retrospective assessment,” Mr King said. “You cannot use these reports to understand how the Australian dollar progresses and develops in your daily life.”
The goal, he added, is to better understand both the objective events and subjective experiences that shape alcohol use in real time, and how these compare to what people report later.
To explore this question, researchers surveyed 496 young adults in Washington state between the ages of 18 and 22, all of whom reported using alcohol or marijuana at least once a week. Participants completed retrospective self-reports at the beginning of the study and again 6 months later. They also received short surveys on their mobile phones five times a day and completed real-time assessments over eight weeks.
The study focused on a subset of AUD symptoms, including hazardous use, social/occupational problems, failure to meet obligations, craving, tolerance, heavy/prolonged drinking, and time spent obtaining/using alcohol. Participants were followed over eight long weekends, from Thursday to Sunday, when drug use tends to be highest among young people.
The results revealed clear differences in what people remembered accurately. Participants were generally good at remembering specific, memorable events, such as getting into a fight, getting hurt, or missing work or school. But compared to more objective events, what they said at that moment or that day doesn’t match up very well with retrospective memory.
“It’s fair to say that people are better at remembering something that happened to them than they are about how they felt about it,” King said.
Daily reports of symptoms also predicted how participants described their alcohol use six months later, suggesting that real-time data may capture patterns associated with long-term risk.
In clinical settings, Kang said, patients often have a hard time remembering or recognizing their own drinking patterns. Real-time tracking could help people see those patterns more clearly and know when they need help. The researchers also noted that AUD can vary widely between people, making more detailed real-time data particularly valuable.
The researchers cautioned that one limitation was that many participants used both alcohol and cannabis, making it difficult to determine whether certain symptoms were caused by alcohol alone or by the combination. Future analysis will aim to explain this, Kang said.
Although real-time monitoring is unlikely to replace retrospective evaluation, the researchers said the two approaches may complement each other.
“Real-time and retrospective evaluations are not interchangeable because they have different strengths,” King said. “Real-time assessment tells us how someone is experiencing the world at that moment. Retrospective assessment combines an aggregated moment and how people evaluate or understand it.”
Using both approaches together could help clinicians and researchers move beyond one-size-fits-all evaluation methods, he said.
“When you have a hammer, everything looks like a nail. We need to build and refine these tools so that they can be used in less sensitive ways,” he says.
Researchers continue to expand their work by incorporating new technologies such as transdermal alcohol biosensors and GPS tracking to better understand individual behavior and environment in real time.
