“…The current study was then set out to investigate the effect of drug detoxification on acoustic features of speech in drug users. Considering that heroin is one of the most prevalent drugs of abuse in China [ 33 ], the abstinent heroin users with different durations of detoxification (i.e., the last drug use was within a period of less than 2 years, 2 years, and longer than 2 years) were involved in the current study. Speech recordings were then collected from sixty-six male abstinent heroin users, twenty-two of whom have been in drug detoxification for less than 2 years, thirty-seven have been in drug detoxification for 2 years, and seven have been in drug detoxification for longer than 2 years.…”

This study aims to investigate the effect of detoxification on acoustic features of Mandarin speech. Speech recordings were collected from 66 male abstinent heroin users with different durations of drug detoxification, specifically early abstinent users with a detoxification duration of less than 2 years, sustained abstinent users with 2 years of detoxification, and long-term abstinent users with a detoxification duration of more than 2 years. The results of the acoustic analyses showed that early abstinent users exhibited lower loudness, relative energies of F1, F2, and F3, higher H1–A3, and fewer loudness peaks per second, as well as a longer average duration of unvoiced segments, compared to the sustained and long-term abstinent users. The findings suggest that detoxification may lead to a rehabilitation process in the speech production of abstinent heroin users (e.g., less vocal hoarseness). This study not only provides valuable insights into the effect of detoxification on speech production but also provides a theoretical basis for the speech rehabilitation and detoxification treatment of heroin users.

IMPORTANCE: Cognitive bias modification (CBM) programs have shown promise in treating psychiatric conditions, but they can be perceived as boring and repetitive. Incorporating gamified designs and adaptive algorithms in CBM training may address this issue and enhance engagement and effectiveness. OBJECTIVE: To assess the efficacy of an adaptive approach bias modification (A-ApBM) paradigm with gamified designs and dynamic difficulty adjustments in reducing cue-induced craving in individuals with methamphetamine use history. DESIGN: Randomized controlled trial with three study groups: Adaptive ApBM (A-ApBM), Static ApBM (S-ApBM), and control. SETTING: Twelve community-based rehabilitation centers in Sichuan, China. PARTICIPANTS: Individuals aged 18-50 with methamphetamine dependence were randomized. INTERVENTION: A-ApBM and S-ApBM groups engaged in ApBM training using a smartphone application for four weeks. A-ApBM used an adaptive algorithm to dynamically adjust the difficulty level based on individual performance, while S-ApBM had a static difficulty level. MAIN OUTCOMES AND MEASURES: Cue-induced craving scores assessed using a visual analog scale at baseline, post-intervention, and at week-16 follow-up. RESULTS: The A-ApBM group showed a significant reduction in cue-induced craving scores at post-intervention compared to baseline (p = 0.02). The reduction remained significant at the week-16 follow-up (p = 0.01). No significant changes were observed in the S-ApBM and control groups. CONCLUSION AND RELEVANCE: The adaptive ApBM paradigm with gamified designs and dynamic difficulty adjustments may be an effective intervention for reducing cue-induced craving in individuals with methamphetamine use history. This approach improves engagement and personalization, potentially enhancing the effectiveness of CBM programs. Further research is needed to validate these findings and explore the application of adaptive ApBM in other psychiatric conditions. TRIAL REGISTRATION: Registered at clinicaltrials.gov (IDNCT05794438).
