Loneliness, anxiety, and depression are common problems for older adults in long-term care. Reminiscence therapy is a non- pharmacological intervention that may be of some benefit. In comparison to individual reminiscence therapy, group reminiscence therapy is a preferred option when dealing with the resource constraints of long-term care. The current study aims to understand the researcher has done an extensive literature review to understand in depth concepts and ideas about Reminiscence Therapy on Depression among the elderly. The objective of this systematic review is to provide healthcare professionals with information to assist in their decision to utilize reminiscence therapy for depression reduction in older adults outside of the primary care setting. Reviewed studies that were randomized controlled trials not only varied in person, outcome measurement, control, and exposure/intervention, the results of these studies was also diverse. About half of these studies showed that reminiscence therapy resulted in a statistically significant decrease in depression. Despite that reminiscence therapy requires further testing, it should be considered as a valuable intervention. Future directions of studies on reminiscence therapy are suggested.
