Individuals who recognize their experiences as depression, perceive that the symptoms have serious consequences, and believe that treatment will be effective are significantly more likely to seek therapy or medication. This new study was published in BMJ Mental Health.
Depression is one of the most common mental health conditions worldwide, yet a substantial proportion of affected individuals never receive treatment. Researchers have pointed to hurdles including long waitlists, limited providers, or missed referrals.
However, individual-level factors have received less attention. Illness beliefs—how people perceive the nature, consequences, and treatability of their symptoms—are known to influence health behaviors in physical illnesses. Yet, these have been less studied in untreated populations with depression.
Led by Matthias Klee and his team from Heidelberg University Hospital, Germany, the researchers sought to investigate if illness beliefs can predict who follows through with treatment after an online screening.
Klee’s team focused on individuals who had at least moderate symptoms, had not been treated or diagnosed in the past year, and were recruited into a nationwide German trial that delivered automated feedback after web‑based depression screening.
To test this, the researchers analyzed data from 871 adults, aged 37.5 years on average (73% female), who completed follow-up six months after screening. Participants filled out a short questionnaire about their beliefs right after the screening. It asked, for example, how much their symptoms were interfering with life, if they thought treatment could help, whether they could imagine that they were experiencing depression, and if this was their first time with such problems.
Researchers then assessed whether participants had initiated psychotherapy or antidepressant medication within six months. The results revealed that 233 (26.8%) participants had undertaken treatment.
Three beliefs emerged as significant predictors of treatment initiation. First, individuals who believed their symptoms had a substantial impact on daily life were more likely to seek care.
Second, those who believed treatment could help were more likely to begin therapy or medication.
Third—and most powerfully—those who recognized their symptoms as depression were much more likely to take action. Statistically, each step up in believing treatment would help was linked to a meaningful increase in the chances of starting care, and identifying one’s symptoms as depression was associated with up to an approximately 57% relative increase in the predicted probability of treatment initiation.
These patterns held even when the analysis accounted for many other factors, including the severity of symptoms, whether a structured diagnostic interview suggested major depression, and if the individual already had a preference for seeing a general practitioner or psychotherapist.
“Our findings highlight the importance of illness beliefs for the patient journey mounting at the uptake of depression treatment as a final result of help-seeking. We find that illness beliefs about consequences, treatment control and illness identity predict uptake of depression treatment in a naturalistic setting,” the authors concluded.
However, there are some caveats. For instance, the six-month follow-up may have been too short to capture all treatment initiation, given long wait times for care.
