This study examined various characteristics and trends among older adults (65+) with problem gambling, and compared their profiles with a younger age group (18-64). The sample included 345 older and 3,499 younger gamblers, and consisted of subjects that sought treatment in California as part of UCLA’s CALGETS program between 2018 and 2023. Data was collected through surveys administered by treatment providers. We hypothesized co-occurring mental and physical health deficits, variation in gambling behavior, and a consistent gender difference within the group of older adults with problem gambling. Surprisingly, there was almost no difference in gender ratio between older adult gamblers, among other key findings.
