Description

The Assessment Method for Best Practices in Substance Use Prevention and Treatment (SEID-50) is an evaluation instrument designed to assess the quality, organization, methodological characteristics, and effectiveness of prevention and treatment programs related to substance use. The tool is based on contemporary European standards and aims to support the systematic documentation and evaluation of interventions implemented in both preventive and therapeutic settings.

The SEID-50 focuses on identifying whether programs and services incorporate established best practices, appropriate organizational procedures, evidence-based approaches, and quality assurance mechanisms. Unlike traditional psychometric instruments that primarily measure individual psychological characteristics, the SEID-50 functions as an organizational and program evaluation framework.

The tool is particularly relevant for organizations involved in substance use prevention, addiction treatment, therapeutic communities, and public health interventions, providing a structured approach for assessing program implementation and promoting continuous improvement.

Data Analysis and Use

Data collected through the SEID-50 are analyzed using both quantitative and qualitative approaches in order to evaluate the degree to which best practices are incorporated into prevention and treatment programs.

Quantitative analysis focuses on calculating the percentage of positive responses within each evaluation axis. These indicators provide an overview of the level of implementation of required practices, procedures, and quality standards.

Qualitative analysis involves the examination of explanatory comments, supporting documentation, and evidence provided for each evaluated area. This information allows a deeper understanding of program strengths, areas requiring improvement, and contextual factors affecting implementation.

The results obtained from the SEID-50 may be used for internal quality evaluation, organizational planning, service improvement, funding documentation, accountability procedures, and strategic development of substance use interventions.

The tool supports organizations in monitoring their compliance with established standards and identifying opportunities for enhancing the effectiveness and sustainability of their programs.

Objective

The primary objective of the SEID-50 Assessment Method is to evaluate the extent to which substance use prevention and treatment programs follow recognized best practice standards.

The instrument aims to assess the structure, organization, methodological framework, implementation procedures, and outcomes of interventions, while promoting transparency, accountability, and continuous quality improvement.

Through systematic evaluation, the SEID-50 contributes to the development of evidence-informed services and supports organizations in improving the quality of care provided to individuals affected by substance use problems.

Structure and Content

The SEID-50 consists of evaluation criteria that examine the presence or absence of specific practices, procedures, and organizational elements considered important for effective prevention and treatment programs.

The assessment covers multiple aspects of service quality, including program organization, methodological characteristics, implementation processes, documentation procedures, and evaluation practices.

The instrument is completed based on available evidence and supporting documentation. Positive responses require justification through relevant records or materials, ensuring that assessment decisions are based on objective information rather than subjective judgments.

The tool is designed for use by trained professionals familiar with program evaluation and quality assessment procedures.

Scoring

The SEID-50 uses a binary response format, where each criterion is evaluated as “Yes” or “No” depending on whether the required practice, procedure, or element is present.

Positive responses must be supported by appropriate documentation and are further examined according to predefined evaluation axes described in the completion guide.

The final evaluation is based on the proportion of implemented practices within each axis, with higher percentages indicating greater adherence to best practice standards.

Unlike conventional psychometric scales, the SEID-50 does not produce an individual psychological score. Instead, it provides an evaluation profile of program quality, implementation level, and alignment with established standards.

Statistical Analysis

Statistical analysis of SEID-50 results focuses primarily on descriptive evaluation indicators rather than traditional psychometric analyses.

Quantitative analysis may include calculation of implementation percentages for each assessment domain, comparison of results between programs or evaluation periods, and monitoring of improvement over time.

Qualitative analysis complements quantitative findings by examining documentation, explanatory information, and contextual factors related to program implementation.

The combination of quantitative and qualitative analysis allows organizations to identify strengths, weaknesses, and priorities for quality improvement.

Validity

The SEID-50 demonstrates content and methodological validity through its alignment with internationally recognized standards for substance use prevention and treatment evaluation.

The tool has been developed in accordance with evaluation principles established by organizations such as the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) and the World Health Organization (WHO).

Its validity is supported by its consistency with established criteria for assessing public health interventions and addiction treatment services, as well as by its application in programs implemented by KETHEA.

Because the SEID-50 is primarily an organizational evaluation method rather than a psychological measurement scale, validity is examined through its relevance, completeness, and applicability to program assessment rather than through traditional construct validity models.

Reliability

The reliability of the SEID-50 is reflected in the consistency and completeness of the information collected when the tool is applied by trained professionals.

The instrument does not rely on conventional psychometric reliability indicators, such as Cronbach’s alpha, because it is not designed as a self-report psychological scale. Instead, reliability is supported through standardized completion procedures, detailed instructions, predefined evaluation criteria, and documentation requirements.

These characteristics contribute to consistent application of the assessment method across different programs and evaluation contexts.
