Digital Mental Health Research: Who Really Gets Left Out?

Digital mental health studies often promise better access to care, but new findings suggest some groups still get overlooked. A review of 57 trials found that while nearly all studies shared age and gender details, many skipped key details about participants’ backgrounds. Minority ethnic groups, men, unemployed people, and those with less education were rarely included in meaningful numbers.Rural residents showed up more in Australian trials, but other groups—like people in poverty or those with disabilities not linked to mental health—were almost never tracked. Most research focused on adults between 18 and 50, leaving out children, older adults, and other age groups. The review also looked at why some people get left out. Poor internet access, lack of tech skills, and disabilities made participation harder. On the other hand, having a guide, therapist, or simpler sign-up process helped more people join. The bottom line? Digital trials aren’t yet reaching everyone equally. Without better representation, these studies might miss what works—and what doesn’t—for different groups. That could make digital mental health tools less useful for people who need them most.
