The effectiveness of a sentence completion test for depression screening using large language models
Porkaew P.; Zhu T.; Li A.; Chuenphitthayavut K.; Porkaew P.; Srinakharinwirot University (2025-09-01)
Depressive symptoms pose a significant mental health challenge globally, including in Thailand. The aim of this study was to assess the effectiveness of a sentence completion test for depression using large language models (LLMs). To improve objectivity and reduce bias in assessments, this study detects and classifies the trends in depression, modernizing the screening process with a newly developed depression sentence completion test. This research examines the four key areas: 1) family, 2) society, 3) health, and 4) self-concept among 373 participants, aged 20 to 40. Additionally, four models were applied to test: 1) LLAMA 3.1-8B, 2) Gemma2-9B, 3) Qwen2-7B, and 4) Typhoon1.5-7B. The result revealed that health, self-concept, and DIFF (Difference) were strongly related to sentiment levels with strong positive values of 0.48, 0.49, and 0.54, respectively, which might mean that they are significant indicators of depression risk. Family and society had positive but lower values of 0.27 and 0.19, respectively. Statistical validation confirms model reliability with a 0.78 lower bound accuracy (p ≤ .05). In the evaluation of all Thai-compatible LLMs, random forest models consistently performed better than decision tree classifiers in the classification of depression risk. LLaMA3.1 and Gemma2 produced the highest sensitivity. Ethical problems have to be considered when using LLMs in mental health. Embedding diverse populations and dynamic updating to sample data in future studies will assure greater accuracy and generalization across different demographic groups.

This study presents, for the first time, the meticulous integration of lab-made Prussian blue analogs (PBAs) into graphene ink. The PBAs were methodically incorporated into graphene ink to produce a homogeneous and uniform composite material. Subsequently, the formulated ink was screen-printed onto a substrate, which resulted in a screen-printed graphene–PBAs incorporation electrode (SPG(PBAs)E). To further enhance surface functionalization, this design is modified with dopamine (DA). The DA-modified SPG(PBAs)E (DA/SPG(PBAs)E) enables the simultaneous electrochemical detection of homovanillic acid (HVA) and vanillylmandelic acid (VMA), two key neurotransmitter metabolites. The synergistic properties of graphene and PBAs provide a high surface area, conductivity, and electrocatalytic activity, while dopamine acts as a bioinspired linker, improving sensitivity for the detection. The developed sensor demonstrated excellent sensitivity, selectivity, and stability in complex matrices. After the systematic optimization of ink formulation and electrochemical parameters, the linear concentration ranges were 5–50 µM for HVA and 1–25 µM for VMA, with detection limits of 1.46 and 0.29 µM, respectively. In practical applications, the proposed electrode effectively analyzed HVA and VMA in human urine samples, yielding satisfactory results with recovery values falling within an acceptable range of 89.60 – 118.46 %. This integrated approach offers a promising strategy for developing compact, cost-effective, and point-of-care diagnostic tools for clinical neurochemical monitoring.
The influence of mindfulness, resilience, and self-efficacy on foreign language anxiety among chinese college students
Li H.; Srisawat P.; Voracharoensri S.; Li H.; Srinakharinwirot University (2025-11-01)
This study explores the effects of mindfulness, resilience, and self-efficacy on foreign language anxiety among Chinese college students and identifies the most significant predictor of foreign language anxiety. Employing a quantitative approach, data were collected from 323 English as a foreign language students using validated scales measuring these variables. Pearson correlation analyses revealed significant negative correlations of self-efficacy (r=-0.538, p<0.01), resilience (r=-0.372, p<0.01), and mindfulness (r=-0.331, p<0.01) with foreign language anxiety. Multiple regression analysis indicated that self-efficacy was the most impactful variable for predicting foreign language anxiety, while mindfulness also significantly predicted foreign language anxiety, but resilience did not. These findings underscore the pivotal part played by self-efficacy in reducing foreign language anxiety and suggest that enhancing self-efficacy can improve language study experiences. The research offers meaningful understandings regarding the mechanisms of foreign language anxiety and offers practical recommendations for educators to implement strategies aimed at boosting students’ self-efficacy, with implications for future research and practice.
A Simple and Rapid Synthesis of Spherical Silver Phosphate (Ag3PO4) and Its Antimicrobial Activity in Plant Tissue Culture

A simple and rapid precipitation process was successfully employed to prepare silver phosphate (SP, Ag3PO4). Two different phosphate sources: diammonium hydrogen phosphate ((NH4)2HPO4) and dipotassium hydrogen phosphate (K2HPO4) were applied separately as the precursor, obtaining ((NH4)2HPO4)− and K2HPO4− derived SP powders, named SP-A or SP-P, respectively. Fourier transform infrared (FTIR) spectra pointed out the vibrational characteristics of P–O and O–P–O interactions, confirming the presence of the PO43– functional group for SP. X-ray diffraction (XRD) patterns revealed that the SP crystallized in a cubic crystal structure. Whereas the field emission scanning electron microscope (FESEM) exposed spherical SP particles. The potentially antibacterial activity of SP-A and SP-P against bacterial Bacillus stratosphericus, yeast Meyerozyma guilliermondii, and fungal Phanerodontia chrysosporium was subsequently investigated. All studied microorganisms were recovered and isolated from the aquatic plant during the tissue culture process. The preliminary result of the antimicrobial test revealed that SP-A has higher antimicrobial activity than SP-P. The superior antimicrobial efficiency of SP-A compared to SP-P may be attributed to its purity and crystallite size, which provide a higher surface area and more active sites. In addition, the presence of potassium-related impurities in SP-P could have negatively affected its antimicrobial performance. These findings suggest that SP holds potential as an antimicrobial agent for maintaining sterility in tissue cultures, particularly in aquatic plant systems. The growth of both B. stratosphericus and M. guilliermondii was suppressed effectively at 30 ppm SP-A, whereas 10 ppm of SP-A can suppress P. chrysosporium development. This present work also highlights the potential of SP at very low concentrations (10–30 ppm) for utilization as an effective antimicrobial agent in tissue culture, compared to a commercial antimicrobial agent, viz., acetic acid, at the same concentration.

Sakdapat N.; Yuangngoen P.; Ngamcharoen P.; Sakdapat N.; Srinakharinwirot University (2025-06-01)
Objectives: This study seeks to provide a complete communication model that integrates the SMCR communication theory with the Health Communication Model, utilising the Interactionism Model as the foundational framework. It investigates causal correlations among factors and corroborates findings through a subsequent qualitative phase to improve communication techniques that promote healthy behaviours and well-being. Methods: A mixed methods approach employing an explanatory sequential design was utilised. Phase 1 was a quantitative investigation with 800 elderly volunteers (mean age = 68 years and 9 months) selected by stratified quota sampling. Data were gathered utilising 13 validated questionnaires (6-point rating scale; overall reliability = 0.755). Phase 2 employed a phenomenological methodology involving 18 people, aged 60 to 80, selected by purposive and snowball sampling techniques. Data were collected via focus groups and comprehensive interviews to investigate communication obstacles and guide strategic development. Results: Quantitative results corroborated all five theories. The model fit indices were acceptable: χ² = 98.623, df = 49, p = 0.013, RMSEA = 0.037, CFI = 0.986, TLI = 0.985, SRMR = 0.052. Principal factors encompassed communication for health literacy (β = 0.804), quality of life (β = 0.843), psychological resilience (β = 0.709), information exposure (β = 0.743), and health literacy (β = 0.832). 2) Qualitative findings indicated: (a) urban elderly individuals possessed superior access to health information owing to familial support, educational background, and media exposure; (b) intricate content and digital access impediments obstructed engagement; (c) peer communication was regarded as reliable; (d) simplicity and usability were favoured in technological applications; and (e) communication tools that enhance familial interaction were greatly esteemed. Conclusions: The study advocates for the improvement of health-oriented media literacy and the implementation of routine mental health evaluations every three months. Government assistance is crucial for the expansion of healthcare networks for the elderly. Eight strategic directions are recommended: 1) Age-appropriate language; 2) Diverse and accessible media; 3) Participatory communication; 4) Family and social involvement; 5) Behavior-driven activities; 6) Gradual technology integration; 7) Consistent follow-up; 8) Culturally sensitive messaging.
