This invention discloses a method and
system for generating depression intervention programs based on nostalgia-guided prompts, belonging to the field of computer-aided
psychological intervention technology. The method involves acquiring digital representations of nostalgia-guided prompts uploaded by the user's terminal, deeply analyzing and extracting entity object identifiers and scene context identifiers, matching these identifiers with preset
life time period division axes to determine corresponding personal historical period tags, and retrieving a set of positive emotional
arousal keywords from an emotion
association mapping table based on these tags. This constructs an intervention cue sequence containing multimodal cues, generates a structured intervention program with a progressive relationship, and pushes it to the user. The order or content of unexecuted cues is dynamically adjusted based on real-time feedback signals after user execution. This invention significantly improves the
personalization, semantic understanding depth, and clinical response flexibility of depression intervention programs through fine-grained semantic analysis of nostalgia-guided prompts, precise mapping of personal historical periods, and a feedback-driven dynamic update mechanism.
