这项研究为心理健康评估提供了非侵入式新方法——用几分钟语音就能预测幸福感，做临床心理学或语音分析的团队值得关注，零样本方案降低了部署门槛。
研究团队利用大语言模型（LLM）从自发语音中零样本预测Ryff心理幸福感（PWB）分数。基于PsyVoiD数据库中111名参与者的几分钟语音录音，评估了12种指令微调LLM（包括Llama-3、Ministral、Mistral、Gemma-2/3、Phi-4、DeepSeek和QwQ-Preview）。与临床心理学和语言学专家合作开发了领域提示词。结果显示，LLM能从语音中提取语义线索，在80%的数据上达到最高0.8的Spearman相关性。研究还通过统计分析解释预测变异性和偏差，并用词云突出驱动预测的语言特征。
Predicting Psychological Well-Being from Spontaneous Speech using LLMs
We investigate the use of Large Language Models (LLMs) for zero-shot prediction of Ryff Psychological Well-Being (PWB) scores from spontaneous speech. Using a few minutes of voice recordings from 111 participants in the PsyVoiD database, we evaluated 12 instruction-tuned LLMs, including Llama-3 (8B, 70B), Ministral, Mistral, Gemma-2-9B, Gemma-3 (1B, 4B, 27B), Phi-4, DeepSeek (Qwen and Llama), and QwQ-Preview. A domain-informed prompt was developed in collaboration with experts in clinical psychology and linguistics. Results show that LLMs can extract semantically meaningful cues from spontaneous speech, achieving Spearman correlations of up to 0.8 on 80\% of the data. Additionally, to enhance explainability, we conducted statistical analyses to characterise prediction variability and systematic biases, alongside keyword-based word cloud analyses to highlight the linguistic features driving the models' predictions.
