Understanding User Perceptions on Personalized Narrative Interventions Using Large Language Models

Core Concepts

LLM-enhanced stories were perceived to be more effective than human-written stories in communicating key takeaways, promoting reflection, and reducing belief in negative thoughts, while maintaining similar levels of authenticity.

Abstract

This study investigated how young adults perceive various aspects of LLM-enhanced stories designed to assist individuals in managing negative thoughts, compared to human-written stories from past digital mental health (DMH) interventions.
The key findings are:

LLM-enhanced stories were perceived to be better than human-written stories in communicating key takeaways, promoting reflection, and reducing belief in negative thoughts.

LLM-enhanced stories were seen as similarly authentic to human-written stories, highlighting the potential of LLMs in helping young adults manage their struggles.

Participants appreciated how the LLM-enhanced stories were tailored to their specific circumstances, making the messages more relevant and applicable. However, some felt the stories were too precisely mirrored to their inputs, reducing the sense of authenticity.

Participants suggested the need to maintain a careful balance between relatability and avoiding implausibility in LLM-enhanced narratives. They also highlighted the importance of refining the tone and wording of AI-generated content.

The findings provide crucial design considerations for future narrative-based digital mental health interventions leveraging large language models.

Stats

"Now I understand that everybody has their own timing and even if it takes me more time to find out what I want, at least I'll be happy and sure of what I want to do."
The story helped me think of potential ways I can manage negative thoughts.
I would love to read similar stories in the future.

Quotes

"It explains what I am currently going through perfectly to a tee."
"To be fair, the story did give me a step back to look at my situation from a different perspective. It made me think 'Maybe I am a little too harsh on myself.'"
"It's not that easy to just focus on what you have in control and the rest will follow in reality. When you have a lot of things on your plate it gets stressful to manage."

Deeper Inquiries

How can LLM-enhanced narratives be designed to strike the right balance between relatability and avoiding implausibility?

To design LLM-enhanced narratives that effectively balance relatability and plausibility, several strategies can be employed. First, contextual grounding is essential; narratives should be rooted in realistic scenarios that reflect common experiences faced by the target audience. This can be achieved by utilizing data from previous digital mental health (DMH) interventions and incorporating user feedback to ensure that the narratives resonate with real-life challenges.
Second, prompt engineering plays a crucial role in guiding the LLM to generate content that maintains a balance between relatability and realism. By providing structured prompts that emphasize the importance of authenticity and realistic outcomes, developers can encourage the LLM to produce narratives that feel genuine while avoiding exaggerated or overly optimistic portrayals.
Third, iterative testing and refinement of generated narratives can help identify elements that may come across as implausible. Engaging users in the evaluation process allows for the collection of qualitative feedback, which can inform adjustments to the narratives, ensuring they remain relatable without straying into the realm of the unrealistic.
Finally, incorporating diverse perspectives within the narratives can enhance relatability while maintaining plausibility. By showcasing a range of experiences and outcomes, the narratives can reflect the complexity of real-life situations, making them more relatable to a broader audience while avoiding the pitfalls of oversimplification.

What are the potential risks of over-personalization in LLM-enhanced narratives, and how can they be mitigated?

Over-personalization in LLM-enhanced narratives poses several risks, including the potential for reinforcing negative thought patterns and creating a sense of detachment from broader experiences. When narratives are overly tailored to individual user inputs, they may inadvertently validate harmful beliefs or cognitive distortions, leading to a lack of critical reflection on those thoughts.
To mitigate these risks, it is essential to implement content moderation strategies that ensure narratives adhere to evidence-based psychological principles. This can involve preloading the LLM with validated mental health content and guidelines that promote healthy coping mechanisms, thereby preventing the generation of narratives that could reinforce negative thinking.
Additionally, incorporating generalized themes alongside personalized elements can help maintain a balance. By blending individual experiences with broader, relatable themes, narratives can encourage users to reflect on their situations without feeling isolated in their struggles.
Finally, user education is vital. Providing users with context about the nature of the narratives and encouraging them to engage critically with the content can foster a more balanced perspective, reducing the likelihood of over-identification with the narratives.

How can the tone and wording of LLM-generated content be refined to enhance the authenticity and impact of narrative interventions?

Refining the tone and wording of LLM-generated content is crucial for enhancing the authenticity and impact of narrative interventions. One effective approach is to employ human-in-the-loop methodologies, where human experts review and edit the generated narratives to ensure they align with the desired emotional tone and language style. This collaborative process can help maintain a conversational and empathetic tone that resonates with users.
Another strategy involves utilizing diverse training datasets that include a variety of writing styles and emotional tones. By exposing the LLM to a rich array of narratives, it can learn to generate content that reflects a more authentic voice, capturing the nuances of human emotion and experience.
Incorporating feedback loops from users can also significantly enhance the refinement process. By soliciting user input on the tone and wording of narratives, developers can identify areas for improvement and adjust the LLM's output accordingly. This iterative feedback mechanism ensures that the narratives remain engaging and relatable.
Finally, focusing on specific language techniques, such as using vivid imagery, relatable metaphors, and emotionally charged language, can enhance the narrative's impact. By crafting narratives that evoke strong emotional responses, users are more likely to connect with the content, leading to deeper reflection and engagement with the material.
