# Chatbots’ Empathetic Conversations and Responses: A Qualitative Study of Help‑Seeking Queries on Depressive Moods Across 8 Commercial Conversational Agents

## TL;DR

This study examines how 8 commercial chatbots respond to users discussing depressive moods, finding that some provide empathetic support while most offer only informative replies.

## Contribution

The paper introduces a qualitative analysis of real-world user-chatbot interactions for mental health support, highlighting the need for empathetic communication in chatbots.

## Key findings

- Some chatbots like Replika and SimSimi provided empathetic responses, while others like Alexa and Google Assistant mostly returned search results.
- Mental health chatbots like Woebot used clarification questions, but many failed to address emotional requests effectively.
- The study found a mixed landscape in emotional support, with a call for next-generation chatbots to incorporate therapeutic communication techniques.

## Abstract

While recent studies showed the potential of conversational agents (CAs) to help alleviate depressive moods, the dynamics of user-chatbot interactions in mental health support remain underexplored.

We examine real-world conversations between users and chatbots on depression-related topics to identify patterns in how users seek help and how chatbots provide therapeutic support. We analyzed the responses of 8 commercial chatbots to user queries about depressive moods, examining whether they incorporated therapeutic communication techniques, such as empathy.

Our method has 2 parts. First, we analyzed 13,700 utterances (6850 user queries and 6850 responses) about depressive moods from the commercial chatbot SimSimi, covering 5 English-speaking countries between 2016 and 2021. Using a human-annotated coding approach, we classified user queries into 5 groups based on Rickwood’s help-seeking model and classified chatbot responses into 8 therapeutic communication styles. Empathy was assessed as one of these styles, with responses coded as empathetic when they demonstrated emotional understanding, validation, and reflection. Next, we evaluated the responses of 3 voice assistants (Amazon’s Alexa, Google Assistant, and Apple’s Siri) and 5 chatbots (ChatGPT, Replika, Woebot, Wysa, and SimSimi) to user queries about depressive moods.

In study 1, we examined how SimSimi, a social chatbot trained to encourage users to share their emotions and build rapport, responded to user queries. The majority (3067/4073, 75.3%) indicated depressed feelings, and a smaller portion (168/4073, 4.1%) sought strategies to cope with depression. The chatbot’s responses were largely therapeutic ( 2417/3108, 77.7%), demonstrating empathy (902/3108, 29%), active listening (836/3108, 26.9%), and open-ended questions (679/3108, 21.8%). In study 2, we qualitatively compared response patterns across commercial CAs, revealing that Replika expressed empathy in more than 75% (28/36) of its responses, similar to SimSimi. In contrast, Alexa (15/17, 88.2%), Google Assistant (18/30, 60%), Siri (20/36, 55.6%), and ChatGPT (40/42, 95.2%) typically responded to depression-related queries with search results rather than offering specific solutions for depressive feelings. Mental health chatbots such as Woebot responded to users with clarification questions (97.3%). We also report instances where CAs failed to meet users’ help-seeking needs, instead giving irrelevant responses and ignoring emotional requests.

Our findings reveal a mixed landscape in the emotional support provided by CAs. While some social chatbots delivered empathetic responses that fostered deeper user engagement, most commercial chatbots offered merely informative replies to users’ help-seeking inputs. Recognizing that users seek support from chatbots, we recommend equipping next-generation CAs with capabilities grounded in therapeutic communication, such as empathetic responses.
