Clinical effectiveness, cost-effectiveness and process evaluation of group schema therapy for eating disorders: study protocol for a multicenter randomized controlled trial

BACKGROUND

Eating disorders (EDs), such as (atypical) Anorexia (AN) and Bulimia Nervosa (BN), are difficult to treat, causing socioeconomic impediments. Although enhanced cognitive behavioral therapy (CBT-E) is widely considered clinically effective, it may not be the most beneficial treatment for (atypical) AN and BN patients who do not show a rapid response after the first 4 weeks (8 sessions) of a CBT-E treatment. Alternatively, group schema therapy (GST) may be a valuable treatment for this ED population. Even though GST for EDs has yielded promising preliminary findings, the current body of evidence requires expansion. On top of that, data on cost-effectiveness is lacking. In light of these gaps, we aim to describe a protocol to examine whether GST is more (1) clinically effective and (2) cost-effective than CBT-E for (atypical) AN and BN patients, who do not show a rapid response after the first 4 weeks of treatment. Additionally, we will conduct (3) process evaluations for both treatments.

METHODS

Using a multicenter RCT design, 232 Dutch (atypical) AN and BN patients with a CBT-E referral will be recruited from five treatment centers. Clinical effectiveness and cost-effectiveness will be measured before treatment, directly after treatment, at 6 and at 12 months follow-up. In order to rate process evaluation, patient experiences and the degree to which treatments are implemented according to protocol will be measured. In order to assess the quality of life and the achievement of personalized goals, interviews will be conducted at the end of treatment. Data will be analyzed, using a regression-based approach to mixed modelling, multivariate sensitivity analyses and coding trees for qualitative data. We hypothesize GST to be superior to CBT-E in terms of clinical effectiveness and cost-effectiveness for patients who do not show a rapid response to the first 4 weeks of a CBT-E treatment.

DISCUSSION

To our knowledge, this is the first study protocol describing a multicenter RCT to explore the three aforementioned objectives. Related risks in performing the study protocol have been outlined. The expected findings may serve as a guide for healthcare stakeholders to optimize ED care trajectories.

Methods for think-aloud interviews in health-related resource-use research: the PECUNIA RUM instrument

BACKGROUND

The think-aloud (TA) approach is a qualitative research method that allows for gaining insight into thoughts and cognitive processes. It can be used to incorporate a respondent's perspective when developing resource-use measurement (RUM) instruments. Currently, the application of TA methods in RUM research is limited, and so is the guidance on how to use them. Transparent publication of TA methods for RUM in health economics studies, which is the aim of this paper, can contribute to reducing the aforementioned gap.

METHODS

Methods for conducting TA interviews were iteratively developed by a multi-national working group of health economists and additional qualitative research expertise was sought. TA interviews were conducted in four countries to support this process. A ten-step process was outlined in three parts: Part A 'before the interview' (including translation, recruitment, training), Part B 'during the interview' (including setting, opening, completing the instrument, open-ended questions, closing), and part C 'after the interview' (including transcription and data analysis, trustworthiness).

CONCLUSIONS

This manuscript describes the step-by-step approach for conducting multi-national TA interviews with potential respondents of the PECUNIA RUM instrument. It increases the methodological transparency in RUM development and reduces the knowledge gap of using qualitative research methods in health economics.

Development of an Instrument for the Assessment of Health-Related Multi-sectoral Resource Use in Europe: The PECUNIA RUM

BACKGROUND

Measuring objective resource-use quantities is important for generating valid cost estimates in economic evaluations. In the absence of acknowledged guidelines, measurement methods are often chosen based on practicality rather than methodological evidence. Furthermore, few resource-use measurement (RUM) instruments focus on the measurement of resource use in multiple societal sectors and their development process is rarely described. Thorn and colleagues proposed a stepwise approach to the development of RUM instruments, which has been used for developing cost questionnaires for specific trials. However, it remains unclear how this approach can be translated into practice and whether it is applicable to the development of generic self-reported RUM instruments and instruments measuring resource use in multiple sectors. This study provides a detailed description of the practical application of this stepwise approach to the development of a multi-sectoral RUM instrument developed within the ProgrammE in Costing, resource use measurement and outcome valuation for Use in multi-sectoral National and International health economic evaluAtions (PECUNIA) project.

METHODS

For the development of the PECUNIA RUM, the methodological approach was based on best practice guidelines. The process included six steps, including the definition of the instrument attributes, identification of cost-driving elements in each sector, review of methodological literature and development of a harmonized cross-sectorial approach, development of questionnaire modules and their subsequent harmonization.

RESULTS

The selected development approach was, overall, applicable to the development of the PECUNIA RUM. However, due to the complexity of the development of a multi-sectoral RUM instrument, additional steps such as establishing a uniform methodological basis, harmonization of questionnaire modules and involvement of a broader range of stakeholders (healthcare professionals, sector-specific experts, health economists) were needed.

CONCLUSION

This is the first study that transparently describes the development process of a generic multi-sectoral RUM instrument in health economics and provides insights into the methodological aspects and overall validity of its development process.

International comparability of reference unit costs of education services: when harmonizing methodology is not enough (PECUNIA project)

BACKGROUND

Health problems can lead to costs in the education sector. However, these costs are rarely incorporated in health economic evaluations due to the lack of reference unit costs (RUCs), cost per unit of service, of education services and of validated methods to obtain them. In this study, a standardized unit cost calculation tool developed in the PECUNIA project, the PECUNIA RUC Template for services, was applied to calculate the RUCs of selected education services in five European countries.

METHODS

The RUCs of special education services and of educational therapy were calculated using the information collected via an exploratory gray literature search and contact with service providers.

RESULTS

The RUCs of special education services ranged from €55 to €189 per school day. The RUCs of educational therapy ranged from €6 to €25 per contact and from €5 to €35 per day. Variation was observed in the type of input data and measurement unit, among other.

DISCUSSION

The tool helped reduce variability in the RUCs related to costing methodology and gain insights into other aspects that contribute to the variability (e.g. data availability). Further research and efforts to generate high quality input data are required to reduce the variability of the RUCs.

Associations between muscle mass/strength and healthcare costs/use for patients with cancer: A systematic literature review

PURPOSE

To review published scientific evidence evaluating the potential associations between muscle mass/strength and healthcare use/costs for patients with cancer.

METHODS

In accordance with the predefined protocol for a systematic literature review, studies assessing potential associations between muscle mass/strength and healthcare costs/use in cancer patients were searched on MEDLINE (via Ovid) and on the NHS Economic Evaluation Database in September 2021. Study selection, data extraction and quality assessment were performed by two independent reviewers.

RESULTS

Of 613 studies identified, five met our inclusion criteria. Various outcomes were investigated: for length of hospital stay, one out of three studies reported an association between lower muscle mass and longer hospital stay; for hospital admission, the two identified studies did not highlight muscle weakness as a predictor of hospital admission; for hospital readmission, one out of two studies reported that patients with lower muscle mass had higher rates of hospital readmission; for costs and cost-effectiveness, results of two randomized controlled trials were mixed, with total costs of the intervention higher in one study and lower in the other, leading to opposite cost-effectiveness results.

CONCLUSION

Only five studies evaluating potential associations between mass/strength and healthcare use/costs have been highlighted within this systematic review. The amount of evidence is limited but the studies are also very heterogeneous in regards of study designs, sample size, and type of population included. This important heterogeneity prevents drawing strong conclusions. Because of limited data available, more high quality longitudinal studies are needed to further investigate the relationship between muscle mass/strength and healthcare costs/use.

Aspects and Challenges of Resource Use Measurement in Health Economics: Towards a Comprehensive Measurement Framework

BACKGROUND

While the methods for conducting health economics research in general are improving, current guidelines provide limited guidance regarding resource use measurement (RUM). Consequently, a variety of methods exists, yet there is no overview of aspects to consider when deciding on the most appropriate RUM methodology. Therefore, this study aims to (1) identify and categorize existing knowledge regarding aspects of RUM, and (2) develop a framework that provides a comprehensive overview of methodological aspects regarding RUM.

METHODS

Relevant articles were identified by enrolling a search string in six databases and handsearching the DIRUM database. Included articles were descriptively reviewed and served as input for a comprehensive framework. Health economics experts were involved during the process to establish the framework's face validity.

RESULTS

Forty articles were included in the scoping review. The RUM framework consists of four methodological RUM domains: 'Whom to measure', addressing whom to ask and whom to measure; 'How to measure', addressing the different approaches of measurement; 'How often to measure', addressing recall period and measurement patterns; and 'Additional considerations', which covers additional aspects that are essential for further refining the methodologies for measurement. Evidence retrieved from the scoping review was categorized according to these domains.

CONCLUSION

This study clustered the aspects of RUM methodology in health economics into a comprehensive framework. The results may guide health economists in their decision making regarding the selection of appropriate RUM methods and developing instruments for RUM. Furthermore, policy makers may use these findings to review study results from an evidence-based perspective.

Do Costs in the Education Sector Matter? A Systematic Literature Review of the Economic Impact of Psychosocial Problems on the Education Sector

BACKGROUND

Psychosocial (e.g., anxiety or behavior) problems lead to costs not only in the healthcare sector but also in education and other sectors. As psychosocial problems develop during the critical period of establishing educational trajectories, education costs are particularly relevant in the context of psychosocial problems among children and adolescents.

OBJECTIVES

This study aimed to gain insights into the methods used for the inclusion of education costs in health economics studies and into the proportion of the education costs in relation to the total costs associated with a condition or an intervention.

METHODS

We systematically searched the PubMed, Embase, SSCI, CINAHL, PsycINFO, ERIC, and Econlit databases in August 2019 for economic evaluations of mental health, psychosocial and educational interventions, and cost-of-illness studies of mental, behavioral, and neurodevelopmental disorders conducted from a societal perspective in populations of children and adolescents. An additional search was conducted in February 2021 to update the review.

RESULTS

In total, 49 articles were included in the analysis. The most common cost items were special education, school absenteeism, and various educational professionals (educational psychologist). A variety of methods were employed for the identification, measurement, and/or valuation of education costs. The proportion of education costs to the total costs of condition/intervention ranged from 0 to 67%, with the mean being 18.5%.

DISCUSSION

Since education costs can constitute a significant proportion of the total costs of an intervention or condition, including them in health economics studies might be important in informing optimal resource allocation decisions. Although various methods are available for including education costs in health economics studies, further research is needed to develop evidence-based methods for producing comparable estimates.

The Relative Importance of Education and Criminal Justice Costs and Benefits in Economic Evaluations: A Best-Worst Scaling Experiment

OBJECTIVES

Mental and behavioural disorders (MBDs) and interventions targeting MBDs lead to costs and cost savings in the healthcare sector, but also in other sectors. The latter are referred to as intersectoral costs and benefits (ICBs). Interventions targeting MBDs often lead to ICBs in the education and criminal justice sectors, yet these are rarely included in economic evaluations. This study aimed to investigate the attitudes held by health economists and health technology assessment experts towards education and criminal justice ICBs in economic evaluations and to quantify the relative importance of these ICBs in the context of MBDs.

METHODS

An online survey containing open-ended questions and two best-worst scaling object case studies was conducted in order to prioritise a list of 20 education ICBs and 20 criminal justice ICBs. Mean relative importance scores for each ICB were generated using hierarchical Bayes analysis.

RESULTS

Thirty-nine experts completed the survey. The majority of the respondents (68%) reported that ICBs were relevant, but only a few (32%) included them in economic evaluations. The most important education ICBs were "special education school attendance", "absenteeism from school", and "reduced school attainment". The most important criminal justice ICBs were "decreased chance of committing a crime as a consequence/effect of mental health programmes/interventions", "jail and prison expenditures", and "long-term pain and suffering of victims/victimisation".

CONCLUSIONS

This study identified the most important education and criminal justice ICBs for economic evaluations of interventions targeting MBDs and suggests that it could be relevant to include these ICBs in economic evaluations.

Economic Impact of the Introduction of Outpatient Medical Specialist Care (ASV) of Gastrointestinal Cancer Patients from a German Hospital Management Perspective

INTRODUCTION

The treatment of cancer patients in Germany is characterized by sectoral separation of the in- and outpatient care accompanied by 2 separate reimbursement systems. By introducing the Guideline of Outpatient Medical Specialist Care in accordance with §116b SGB V (ASV) in 2014, the German legislation empowers office-based physicians and hospitals to jointly provide medical care in the ambulatory setting.

METHODS

A 1-year period each before and after the introduction of ASV was compared by means of data from the Center for Integrated Oncology Cologne at the University Hospital of Cologne. Only adults with a reliable diagnosis of gastrointestinal tumor (GIT) were considered.

RESULTS

Overall, 1,872 cases were considered in the analysis showing significant (p < 0.001) higher median values of revenues across ICD-subgroups for ASV (EUR 427.46) compared to Ambulatory Treatments in Hospitals (EUR 234.21). The exemplary analysis of revenues in neoplasms of the pancreas shows EUR 173.69 on average which are only invoiceable through ASV: flat rate incl. surcharges (EUR 117.79; 68%), structure lump sum (EUR 29.49; 17%), positron-emission tomography (PET)/CT (EUR 13.53; 18%), and ASV consultation hour (EUR 12.89; 7%).

DISCUSSION/CONCLUSION

ASV leads to significant higher revenues across different ICD-subgroups for patients suffering from severe GIT. The collaboration of hospital and office-based physicians ensures patient-centered care with accumulated expertise and avoidance of double examinations. Thus, the inclusion of additional services in the Uniform Value Scale (invoiceable for ASV) is legitimated and enables cost-covering care for the involved parties.

Intersectoral Costs and Benefits of Mental and Behavioural Disorders in the Education Sector: an Exploration of Costing Methods

BACKGROUND

The inclusion of indirect spillover costs and benefits that occur in non-healthcare sectors of society is necessary to make optimal societal decisions when assessing the cost effectiveness of healthcare interventions. Education costs and benefits are relevant in the disease area of mental and behavioral disorders, but their inclusion in economic evaluations is largely neglected due to lack of methodological knowledge.

AIM OF THE STUDY

This study aims to explore, using a scoping review, the identification, measurement, and valuation methods used to assess the impact of mental and behavioural disorders on education costs and benefits.

METHODS

A scoping review was conducted to identify articles that were set in the education sector and assessed education costs and benefits. An adapted 5-step approach was used: (i) initating a scoping review; (ii) identifying component studies; (iii) data extraction; (iv) reporting results; (v) discussion and interpretation of findings. Results were summarized in a narrative synthesis per identification, measurement, and valuation method.

RESULTS

177 component articles were identified in the scoping review that reported 61 mutually exclusive education costs and benefits. The nomenclature used to describe the costs and benefits was poorly defined, heterogeneous in nature and largely context dependent. This was also reflected in the diverse number of measurement and valuation methods found in the component articles.

DISCUSSION

This is the first study, which offers a classification of education costs and benefits and costing methods reported by studies set in the education sector. In conclusion, mental and behavioral disorders have a notable impact on a variety of different education costs and benefits.

IMPLICATIONS FOR HEALTH POLICIES

The classification provided in the current study gives an indication of the wide-spread impact of mental and behavioral disorders on the education sector. Hence, the inclusion of relevant education costs and benefits in economic evaluations for mental and behavioral disorders is necessary to make optimal societal decisions.

IMPLICATIONS FOR FURTHER RESEARCH

By exploring a new area of research from a sector-specific perspective, the current study adds to the existing intersectoral cost and benefit literature base. Future research should focus on standardizing costing methods in pharmacoeconomic guidelines and assessing the relative importance of individual education costs and benefits in economic evaluations for specific interventions and diseases.

Exploring the identification, validation, and categorization of the cost and benefits of criminal justice in mental health: the PECUNIA project

BACKGROUND

Mental health disorders and their treatments produce significant costs and benefits in both healthcare and non-healthcare sectors. The latter are often referred to as intersectoral costs and benefits (ICBs). Little is known about healthcare-related ICBs in the criminal justice sector and how to include these in health economics research.

OBJECTIVES

The triple aim of this study is (i) to identify healthcare-related ICBs in the criminal justice sector, (ii) to validate the list of healthcare-related ICBs in the criminal justice sector on a European level by sector-specific experts, and (iii) to classify the identified ICBs.

METHODS

A scientific literature search in PubMed and an additional grey literature search, carried out in six European countries, were used to retrieve ICBs. In order to validate the international applicability of the ICBs, a survey was conducted with an international group of experts from the criminal justice sector. The list of criminal justice ICBs was categorized according to the PECUNIA conceptual framework.

RESULTS

The full-text analysis of forty-five peer-reviewed journal articles and eleven grey literature sources resulted in a draft list of items. Input from the expert survey resulted in a final list of fourteen unique criminal justice ICBs, categorized according to the care atom.

CONCLUSION

This study laid further foundations for the inclusion of important societal costs of mental health-related interventions within the criminal justice sector. More research is needed to facilitate the further and increased inclusion of ICBs in health economics research.

Health-Related Resource-Use Measurement Instruments for Intersectoral Costs and Benefits in the Education and Criminal Justice Sectors

BACKGROUND

Intersectoral costs and benefits (ICBs), i.e. costs and benefits of healthcare interventions outside the healthcare sector, can be a crucial component in economic evaluations from the societal perspective. Pivotal to their estimation is the existence of sound resource-use measurement (RUM) instruments; however, RUM instruments for ICBs in the education or criminal justice sectors have not yet been systematically collated or their psychometric quality assessed. This review aims to fill this gap.

METHODS

To identify relevant instruments, the Database of Instruments for Resource Use Measurement (DIRUM) was searched. Additionally, a systematic literature review was conducted in seven electronic databases to detect instruments containing ICB items used in economic evaluations. Finally, studies evaluating the psychometric quality of these instruments were searched.

RESULTS

Twenty-six unique instruments were included. Most frequently, ICB items measured school absenteeism, tutoring, classroom assistance or contacts with legal representatives, police custody/prison detainment and court appearances, with the highest number of items listed in the Client Service Receipt Inventory/Client Sociodemographic and Service Receipt Inventory/Client Service Receipt Inventory-Children's Version (CSRI/CSSRI/CSRI-C), Studying the Scope of Parental Expenditures (SCOPE) and Self-Harm Intervention, Family Therapy (SHIFT) instruments. ICBs in the education sector were especially relevant for age-related developmental disorders and chronic diseases, while criminal justice resource use seems more important in mental health, including alcohol-related disorders or substance abuse. Evidence on the validity or reliability of ICB items was published for two instruments only.

CONCLUSION

With a heterogeneous variety of ICBs found to be relevant for several disease areas but many ICB instruments applied in one study only (21/26 instruments), setting-up an international task force to, for example, develop an internationally adaptable instrument is recommended.

Cost-effectiveness of preventive case management for parents with a mental illness: a randomized controlled trial from three economic perspectives

Background

The children of parents with a mental illness (COPMI) are at increased risk for developing costly psychiatric disorders because of multiple risk factors which threaten parenting quality and thereby child development. Preventive basic care management (PBCM) is an intervention aimed at reducing risk factors and addressing the needs of COPMI-families in different domains. The intervention may lead to financial consequences in the healthcare sector and in other sectors, also known as inter-sectoral costs and benefits (ICBs). The objective of this study was to assess the cost-effectiveness of PBCM from three perspectives: a narrow healthcare perspective, a social care perspective (including childcare costs) and a broad societal perspective (including all ICBs).

Methods

Effects on parenting quality (as measured by the HOME) and costs during an 18-month period were studied in in a randomized controlled trial. Families received PBCM (n = 49) or care as usual (CAU) (n = 50). For all three perspectives, incremental cost-effectiveness ratios (ICERs) were calculated. Stochastic uncertainty in the data was dealt with using non-parametric bootstraps. Sensitivity analyses included calculating ICERs excluding cost outliers, and making an adjustment for baseline cost differences.

Results

Parenting quality improved in the PBCM group and declined in the CAU group, and PBCM was shown to be more costly than CAU. ICERs differ from 461 Euros (healthcare perspective) to 215 Euros (social care perspective) to 175 Euros (societal perspective) per one point improvement on the HOME T-score. The results of the sensitivity analyses, based on complete cases and excluding cost outliers, support the finding that the ICER is lower when adopting a broader perspective. The subgroup analysis and the analysis with baseline adjustments resulted in higher ICERs.

Conclusions

This study is the first economic evaluation of family-focused preventive basic care management for COPMI in psychiatric and family services. The effects of the chosen perspective on determining the cost-effectiveness of PBCM underscore the importance of economic studies of interdepartmental policies. Future studies focusing on the cost-effectiveness of programs like PBCM in other sites and studies with more power are encouraged as this may improve the quality of information used in supporting decision making.

A Web-Based Computer-Tailored Alcohol Prevention Program for Adolescents: Cost-Effectiveness and Intersectoral Costs and Benefits

Background

Preventing excessive alcohol use among adolescents is important not only to foster individual and public health, but also to reduce alcohol-related costs inside and outside the health care sector. Computer tailoring can be both effective and cost-effective for working with many lifestyle behaviors, yet the available information on the cost-effectiveness of computer tailoring for reducing alcohol use by adolescents is limited as is information on the costs and benefits pertaining to sectors outside the health care sector, also known as intersectoral costs and benefits (ICBs).

Objective

The aim was to assess the cost-effectiveness of a Web-based computer-tailored intervention for reducing alcohol use and binge drinking by adolescents from a health care perspective (excluding ICBs) and from a societal perspective (including ICBs).

Methods

Data used were from the Alcoholic Alert study, a cluster randomized controlled trial with randomization at the level of schools into two conditions. Participants either played a game with tailored feedback on alcohol awareness after the baseline assessment (intervention condition) or received care as usual (CAU), meaning that they had the opportunity to play the game subsequent to the final measurement (waiting list control condition). Data were recorded at baseline (T0=January/February 2014) and after 4 months (T1=May/June 2014) and were used to calculate incremental cost-effectiveness ratios (ICERs), both from a health care perspective and a societal perspective. Stochastic uncertainty in the data was dealt with by using nonparametric bootstraps (5000 simulated replications). Additional sensitivity analyses were conducted based on excluding cost outliers. Subgroup cost-effectiveness analyses were conducted based on several background variables, including gender, age, educational level, religion, and ethnicity.

Results

From both the health care perspective and the societal perspective for both outcome measures, the intervention was more costly and more effective in comparison with CAU. ICERs differed for both perspectives, namely €40 and €79 from the health care perspective to €62 and €144 for the societal perspective per incremental reduction of one glass of alcohol per week and one binge drinking occasion per 30 days, respectively. Subgroup analyses showed, from both perspectives and for both outcome measures, that the intervention was cost-effective for older adolescents (aged 17-19 years) and those at a lower educational level and, from a health care perspective, the male and nonreligious adolescent subgroups.

Conclusions

Computer-tailored feedback could be a cost-effective way to target alcohol use and binge drinking among adolescents. Including ICBs in the economic evaluation had an impact on the cost-effectiveness results of the analysis. It could be worthwhile to aim the intervention specifically at specific subgroups.

Valuing inter-sectoral costs and benefits of interventions in the healthcare sector: methods for obtaining unit prices

INTRODUCTION

There is a lack of knowledge about methods for valuing health intervention-related costs and monetary benefits in the education and criminal justice sectors, also known as 'inter-sectoral costs and benefits' (ICBs). The objective of this study was to develop methods for obtaining unit prices for the valuation of ICBs.

METHODS

By conducting an exploratory literature study and expert interviews, several generic methods were developed. The methods' feasibility was assessed through application in the Netherlands. Results were validated in an expert meeting, which was attended by policy makers, public health experts, health economists and HTA-experts, and discussed at several international conferences and symposia.

RESULTS

The study resulted in four methods, including the opportunity cost method (A) and valuation using available unit prices (B), self-constructed unit prices (C) or hourly labor costs (D).

DISCUSSION

The methods developed can be used internationally and are valuable for the broad international field of HTA.

[Inter-sectoral costs and benefits arising from mental health (disorders)]

Mental health disorders may bring costs and benefits to areas and sectors lying outside the health care system. However, little is known about these inter-sectoral costs and benefits (ICBs) in spite of the increasing interest in societal cost-benefit analyses (SCBA) that attempt to quantify all costs and benefits involved.<br/> AIM: To present a first inventory of ICBs relating to mental health care and to describe the relation between ICBs and SCBA.<br/> METHOD: We reviewed the literature and conducted a secondary analysis of the results of a previous study.<br/> RESULTS: We found that at least eight mental health disorders were reported to have a (financial) impact on at least three sectors outside the health care system. <br/> CONCLUSION: Further research into ICBs is needed so that future inter-sectoral policy can be better directed and targeted more efficiently.

Inter-sectoral costs and benefits of mental health prevention: towards a new classification scheme

BACKGROUND

Many preventive interventions for mental disorders have costs and benefits that spill over to sectors outside the healthcare sector. Little is known about these "inter-sectoral costs and benefits" (ICBs) of prevention. However, to achieve an efficient allocation of scarce resources, insights on ICBs are indispensable.

AIM OF THE STUDY

The main aim was to identify the ICBs related to the prevention of mental disorders and provide a sector-specific classification scheme for these ICBs.

METHODS

Using PubMed, a literature search was conducted for ICBs of mental disorders and related (psycho)social effects. A policy perspective was used to build the scheme's structure, which was adapted to the outcomes of the literature search. In order to validate the scheme's international applicability inside and outside the mental health domain, semi-structured interviews were conducted with (inter)national experts in the broad fields of health promotion and disease prevention.

RESULTS

The searched-for items appeared in a total of 52 studies. The ICBs found were classified in one of four sectors: "Education", "Labor and Social Security", "Household and Leisure" or "Criminal Justice System". Psycho(social) effects were placed in a separate section under "Individual and Family". Based on interviews, the scheme remained unadjusted, apart from adding a population-based dimension.

DISCUSSION

This is the first study which offers a sector-specific classification of ICBs. Given the explorative nature of the study, no guidelines on sector-specific classification of ICBs were available. Nevertheless, the classification scheme was acknowledged by an international audience and could therefore provide added value to researchers and policymakers in the field of mental health economics and prevention.

IMPLICATIONS FOR HEALTH POLICIES

The identification and classification of ICBs offers decision makers supporting information on how to optimally allocate scarce resources with respect to preventive interventions for mental disorders.

IMPLICATIONS FOR FURTHER RESEARCH

By exploring a new area of research, which has remained largely unexplored until now, the current study has an added value as it may form the basis for the development of a tool which can be used to calculate the ICBs of specific mental health related preventive interventions.
