Dr. Chantal Herberholz (CHE Director)'s latest publication titled "Mental health and legal statuses along the path to citizenship: A qualitative study of minority ethnic urban dwellers in Chiang Mai, Thailand" is now published in Global Health Research and Policy (Tier 1 (top 10%), Health Policy).

Abstract:

Background
Given the lack of legal status, stateless persons often live in precarious situations that put them at risk of mental health problems, especially in urban settings. Moreover, pathways to citizenship may involve navigating different legal statuses over a lifetime, posing additional challenges. Yet, research on the nexus between legal status and mental health remains scant. This study examines the factors that influence the mental health of persons with different legal statuses in a Thai urban context. Thailand has one of the largest stateless populations in the world. In late 2024, however, expedited procedures for long-term residents were announced to address protracted citizenship problems in the country.

Methods
This study employed a qualitative design. Data were collected through 47 in-depth interviews in Northern Thailand’s largest city in July 2023 using purposive and snowball sampling strategies. The interviews were recorded and transcribed verbatim. Thematic analysis, based on a social determinants of mental health framework, was used to analyse the data.

Results
Legal status is related to multiple and interdependent conditions of precarity in the city. Together they create a compounding effect that threatens mental health. The more restricted the rights attached to a legal status, the greater the effect. Past negative life events, adverse employment conditions, and discrimination are key factors that lead to mental health challenges. Obtaining permanent legal status, on the other hand, alleviates legal uncertainty and provides immediate benefits by enhancing access to fundamental rights, with positive effects on mental health. Yet, it cannot reverse pernicious long-term effects of past deprivations, such as foregone opportunities for education and employment, as well as past traumatic events on mental health.

Conclusions
The 2024 landmark move of Thailand’s Cabinet to accelerate progress in resolving citizenship problems for almost 500,000 persons should be accompanied by multi-pronged interventions aimed at improving the social determinants of mental health. In addition, access the mental healthcare should be facilitated.

Another joint publication between a Masters student at the MAAE program MA Applied Economics - Chulalongkorn University and a professor from the Center of Excellence for Health Economics: Yada Wornyordphan and Prof. Kannika Damrongplasit.

The publication, titled "The Impact of Old Age Pension on Subjective Well-being: Evidence from Thailand", is published in Journal of Contemporary Social Sciences and Humanities (Indexed in TCI, tier 1). It is available here: https://so12.tci-thaijo.org/index.php/jcsh/article/view/3953

Abstract:

In this study, an analysis was conducted on the impact of old age pension on subjective well-being in Thailand for those aged 60 and over. Data was obtained from the Health, Aging, and Retirement in Thailand (HART) survey for the 2015 and 2020 waves. A random-effects ordered logit model was employed as the primary method due to the panel structure of the data, while the ordered logit model was used as an alternative methodology. The results indicated that the old age pension has a minimal impact on subjective well-being, relative to other non-financial factors. Other variables such as age, marital status, residential area, region, health status, and income perception tend to have stronger impacts on subjective well-being. Subjective well-being decreases with age. Marriage, living in urban areas, better health status, and higher perception of income are associated with improved subjective well-being. Interestingly, the findings from this study also demonstrate regional differences in subjective well-being.

The CHE's latest publication, co-authored by Supitchaya Changsatja, Chayanis Kositamongkol, Lucksamon Thamlikitkul. Pochamana Phisalprapa and Touchanun Komonpaisarn (a CHE member).

This work is part of Supitchaya's Masters thesis from the Faculty of Economics' MA Applied Economics - Chulalongkorn University program.

The publication in Value in Health Regional Issues (Q1) is titled, "Cost-Utility Analysis of Adjuvant Osimertinib in Resected Epidermal-Growth-Factor-Receptor-Mutated Early-Stage Non-Small Cell Lung Cancer".

Abstract:

Objectives
Lung cancer is the most common cancer and the leading cause of cancer death worldwide. One-third of non-small cell lung cancer (NSCLC) patients are diagnosed at a resectable stage, for which surgery is the standard curative treatment. However, most patients recur within 2 years. Adjuvant osimertinib, a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, significantly reduces recurrence and prolongs survival in completely resected EGFR-mutated NSCLC. This study assessed the cost-utility and budget impact of adjuvant osimertinib versus placebo for resected stage IB-IIIA EGFR-mutated NSCLC from Thailand’s societal perspective.

Methods
A Markov model with a lifetime horizon and 4-week cycle was developed, including 3 health states: disease-free, recurrent disease, and death. Patients received osimertinib or placebo in the disease-free state, with recurrence categorized as locoregional or distant. Subsequent treatments were modeled based on recurrence timing. Health outcomes were obtained from a systematic review, and costs followed Thai health technology assessment guidelines. Results were reported as incremental cost-effectiveness ratios in 2023 USD per quality-adjusted life-years (QALY) gained. Sensitivity analyses addressed uncertainty.

Results
Osimertinib yielded 2.36 additional QALYs at an incremental cost of USD 62 604.90, with an incremental cost-effectiveness ratio of USD 26 474.02/QALY, exceeding Thailand’s willingness-to-pay threshold (USD 4619). An 85.07% price reduction is required for cost-effectiveness. Probabilistic sensitivity analysis showed 0% probability of cost-effectiveness at the current threshold, increasing to 52% at USD 25 981.97/QALY. The 5-year budget impact analysis was estimated at USD 678.73 million.

Conclusions
Adjuvant osimertinib is not cost-effective in Thailand under current pricing but could be with major price reductions or risk-sharing strategies.

Latest article by Dr. Nopphol Witvorapong - a CHE member.

The article titled "Costs and Budget Impact of Scaling-Up Parenting for Lifelong Health for Young Children Program in Thailand" is published in Child: Care, Health and Development (Q1 in Pediatrics and in Public Health). It is coauthored by

Hsu Myat Mon (Faculty of Medicine, Chulalongkorn University), Wilaiwan Pongpaew (Faculty of Medicine, Chulalongkorn University), Amalee McCoy (Faculty of Medicine, Chiang Mai University), Piya Hanvoravongchai (Faculty of Medicine, Chulalongkorn University, currently at NUS).

Abstract

Background
Violence against children poses short- and long-term risks to health, society and economy. The Parenting for Lifelong Health for Young Children (PLH-YC) programme has been shown to be effective in reducing child maltreatment for 2- to 9-year-old children in Thailand. We assessed the costs and budget requirements across multiple scenarios for scaling up the PLH-YC programme in Thailand.

Methods
Five scaling-up scenarios at varying levels were identified through a consultative workshop and semistructured interviews, with implementation planned via existing infrastructures. A bottom-up costing approach was employed to estimate the cost and budget impact using data collected through document review, website search and interviews. Costing was performed using the provider's and societal perspectives.

Results
The cost per caregiver based on the societal perspective ranged from 262 to 300 USD (1 USD = 35.36 THB in 2024). From the provider's perspective, the cost per caregiver trained was estimated at 82–195 USD. Assuming nationwide programme implementation, the estimated total budget impact for 1 year ranged from 50 to 76 million USD.

Conclusions
Scaling-up PLH-YC incurs different unit costs per caregiver depending on the levels of programme delivery. However, budget requirements for all scenarios can be prohibitively high. To increase financial feasibility, programme modifications while maintaining quality, such as fewer parenting sessions or hybrid implementation, should be explored. Strong political commitment and financial support by key stakeholders are necessary for programme adoption and scaling up.

We are pleased to introduce the latest publication by Dr. Nopphol Witvorapong (CHE member), along with his co-authors from the Faculty of Economics, Chulalongkorn University and National Cheng Kung University.

The publication is titled 'Assessing enterprise competitiveness in Thailand: A multi-dimensional approach', published in Asia Pacific Management Review (Q1 in Business, Strategy and Management, IF=5.6)

Abstract:
This study examines enterprise competitiveness in Thailand using a theoretically-grounded five-pillar framework integrating Porter's competitive forces, Resource-Based View, and Dynamic Capabilities Theory. Analyzing 15 indicators across Productivity, Profitability, Image, Stability, and Growth dimensions for over 800 Thai enterprises using the DataStream database, we reveal heterogeneous competitive profiles among top performers with significant industry concentration in Capital Goods, Healthcare, and Consumer Distribution sectors. Our dual-aggregation methodology comparing arithmetic and geometric means demonstrates substantial measurement sensitivity, with arithmetic means proving more appropriate for Thailand's competitive context. Most enterprises exhibit distinctive strengths in specific dimensions rather than balanced excellence, suggesting multiple strategic pathways to competitive advantage. Based on systematic analysis of internal capabilities and external environmental factors, we provide evidence-based recommendations for enhancing enterprise competitiveness through targeted capability development and strategic positioning. This research offers valuable insights for business leaders designing competitive strategies and policymakers strengthening Thailand's economic landscape.
