A Semantic Corpus Comparison Analysis of Couple-Focused Interventions for Problematic Alcohol Use

Area of Science:

• Psychology
• Clinical Psychology
• Addiction Research

Background:

• Spousal involvement in problematic alcohol use interventions enhances treatment efficacy.
• Therapeutic processes explaining these positive effects remain underexplored.
• Partner language use offers a novel lens to examine couple-focused alcohol interventions.

Purpose of the Study:

• To identify semantic themes in partner communication differentiating successful from unsuccessful outcomes in couple-focused alcohol interventions.
• To explore how language use related to alcohol differs between Family Systems Therapy (FST) and Cognitive Behavioural Therapy (CBT) based on treatment success.
• To investigate potential therapeutic change processes linked to spouse language in alcohol treatment.

Main Methods:

• Utilized Wmatrix, a linguistic corpus comparison tool, to analyze speech from 33 couples in a randomized control trial of FST versus CBT.
• Compared semantic themes in partner language between couples with successful and unsuccessful treatment outcomes.
• Conducted post-hoc analyses to examine the context of alcohol-related language use.

Main Results:

• The semantic theme "drinks and alcohol" significantly differentiated treatment outcomes.
• In FST, successful couples used more "drinks and alcohol" language; successful spouses spoke less about the patient's drinking and more about alcohol generally.
• In CBT, successful couples used less "drinks and alcohol" language; successful spouses focused more on patient and couple drinking, less on others' drinking.

Conclusions:

• Spouse language use, specifically concerning alcohol, is a significant factor in the success of couple-focused alcohol interventions.
• Distinct linguistic patterns suggest unique therapeutic processes in FST and CBT.
• Linguistic corpus comparison is a valuable method for understanding couple intervention dynamics and outcomes.
