Accepted Evaluation Instruments in the CONASAMA Registry (Complete Guide)

What assessment instruments does CONASAMA accept?

The assessment instruments accepted in the CONASAMA certificate include standardized tools such as the BAI (Beck Anxiety Inventory), BDI (Beck Depression Inventory), SCL-90-R, and ASSIST (WHO), as they allow for objective assessment of anxiety, depression, general psychological symptomatology, and substance use.

Additionally, to elevate the clinical level of treatment, it is recommended to supplement with instruments such as AUDIT, CAGE, DASS-21, PHQ-9, and GAD-7, which improve diagnostic accuracy, patient monitoring, and clinical decision-making within addiction treatment programs.

Introduction: The most common mistake in rehabilitation centers

Most centers in Mexico believe that complying with CONASAMA means having filled-out forms.

But the reality is different.

CONASAMA doesn't look for papers.
It looks for real clinical structure.

And one of the most important pillars of that structure is the correct use of psychological and substance use assessment instruments.

Without instruments:

• There is no clear diagnosis
• There is no measurement of progress
• There is no clinical support
• There is no quality in treatment

In this article, you will understand not only what instruments to use, but also how to use them strategically within your program.

Why does CONASAMA require assessment instruments?

Because addiction treatment cannot be based on perception.

It must be based on:

• Data
• Measurement
• Evidence

Instruments allow for:

1. Standardizing evaluation

Two patients with the same problem may appear different without objective tools.

2. Detecting comorbidities

Anxiety, depression, trauma, and other psychological problems directly impact treatment.

3. Measuring severity

Experimental use is not the same as severe dependence. An instrument helps to locate the patient more accurately.

4. Justifying clinical decisions

Discharge, phase changes, intensive intervention, or the need for specialized follow-up.

5. Providing real follow-up

Without measurement, there is no demonstrable clinical progress.

Basic instruments accepted by CONASAMA

These are the most commonly used and accepted instruments in clinical practice in Mexico.

BAI (Beck Anxiety Inventory)

The BAI assesses the intensity of anxiety symptoms.

Key features:

• 21 items
• Focus on physical symptoms of anxiety
• Quick to administer

Clinical application:

• Patients in early abstinence
• Cases with high somatic anxiety
• Differentiation between anxiety and physical symptoms related to withdrawal

One of the most common mistakes is to administer it and file it away without real clinical interpretation.

BDI (Beck Depression Inventory)

The BDI measures the severity of depression.

Key features:

• 21 items
• Evaluates emotional, cognitive, and physical symptoms
• Helps detect indicators of suicidal risk

Clinical use:

• Initial evaluation
• Monthly follow-up
• Detection of moderate or severe depression

In addiction treatment, the BDI is particularly useful because many patients not only arrive with problematic use but also with depressive symptoms that affect motivation, adherence, and prognosis.

SCL-90-R

The SCL-90-R is a global psychological symptom assessment tool.

Key features:

• 90 items
• Evaluates multiple clinical dimensions
• Allows for a broader view of the patient's psychological functioning

Clinical use:

• In-depth evaluation at the start of treatment
• Identification of complex symptom patterns
• Cases where multiple comorbidities are suspected

It is one of the most comprehensive tests for obtaining a broader picture of the patient's emotional and psychological state.

ASSIST (WHO)

The ASSIST, developed by the World Health Organization, is one of the most important instruments in addiction treatment.

Evaluates:

• Alcohol
• Tobacco
• Cannabis
• Stimulants
• Opioids
• Polysubstance use

Classifies risk into:

• Low risk
• Moderate risk
• High risk

Clinical use:

• Admission
• Initial patient classification
• Basis for developing the treatment plan

If a center wants to seriously discuss substance use assessment, the ASSIST should be among its basic tools.

Recommended instruments to elevate the clinical level

This is where the quality of the program truly changes. These instruments are not always seen as part of the minimum, but they greatly help to elevate clinical practice and make better-supported decisions.

AUDIT

The AUDIT is specifically designed to assess alcohol consumption.

Advantages:

• Highly validated
• Quick to administer
• Detects risky use, abuse, and probable dependence

Clinical use:

• Patients with a history of alcohol consumption
• Monitoring of clinical evolution
• More specific detection than a general screening

It is an excellent tool to complement the ASSIST when alcohol is a primary substance.

CAGE

The CAGE is a brief four-question test primarily focused on problematic alcohol consumption.

Its questions explore:

• Need to cut down consumption
• Annoyance from criticism
• Guilt associated with consumption
• Morning consumption

Clinical use:

• Rapid screening
• Initial interviews
• Contexts where a brief tool is needed

It does not replace a more complete evaluation, but it works very well as an initial filter.

DASS-21

The DASS-21 evaluates three important areas:

• Depression
• Anxiety
• Stress

Advantages:

• More efficient than using multiple instruments separately
• Useful for clinical follow-up
• Provides a quick overview of the general emotional state

Clinical use:

• Monthly monitoring
• Monitoring of emotional symptoms
• Comparison of evolution during treatment

For centers that want to measure progress more practically, the DASS-21 can be a very useful tool.

PHQ-9

The PHQ-9 is one of the most widely used tools internationally for depression assessment.

Advantages:

• Based on DSM criteria
• Brief and easy to administer
• Includes evaluation of symptoms related to suicidal risk

Clinical use:

• Initial detection
• Monitoring of depressive symptoms
• Clinical and medical contexts

It is ideal when a short, practical, and clinically useful tool is sought.

GAD-7

The GAD-7 evaluates symptoms of generalized anxiety.

Advantages:

• Short
• Accurate
• Easy to administer and interpret

Clinical use:

• Rapid anxiety assessment
• Monthly follow-up
• Monitoring of treatment response

Its simplicity makes it especially useful in centers where consistency in clinical application is sought.

How to structure the application of these instruments within treatment

This is where most centers fail. It's not enough to have tests. They need to be integrated into a logical sequence of evaluation.

Phase 1: Admission

Objective: initial detection and basic clinical classification.

Apply:

• ASSIST
• AUDIT or CAGE
• BDI or PHQ-9
• BAI or GAD-7

This phase allows for a quick overview of substance use, anxiety, and depression from the outset.

Phase 2: Complete clinical evaluation

Objective: deepen symptomatology and obtain a broader profile.

Apply during the first few weeks:

• SCL-90-R
• DASS-21

In this phase, it can be complemented with clinical interview, substance use history, medical review, and psychiatric evaluation if applicable.

Phase 3: Follow-up

Objective: measure progress and adjust clinical decisions.

Suggested application every 4 weeks:

• BDI or PHQ-9
• BAI or GAD-7
• DASS-21

This periodic measurement allows observation of whether the patient is improving, stagnating, or worsening.

Phase 4: Discharge

Objective: document clinical change and close the process with comparable data.

It is recommended to reapply:

• Instruments used at admission

Results are then compared to assess:

• Change in symptoms
• Reduction in severity
• Clinical improvement
• Need for continuity of care

Critical error: applying instruments without integrating them into treatment

This is one of the most common mistakes in many centers:

Instruments are applied, but their results do not influence treatment.

When this happens, tests become:

• A formality
• Paperwork
• Clinical simulation

For them to truly be useful, they must:

• Be interpreted
• Be recorded in the clinical file
• Influence therapeutic objectives
• Help make decisions

If the instrument's result doesn't change anything in the treatment plan, then the instrument remains just a form.

The relationship between instruments and clinical file

All these instruments must be part of the clinical file, and their use must be properly documented.

This includes:

• Date of application
• Result
• Clinical interpretation
• Impact on the treatment plan

If you want to understand how to correctly integrate evaluation into the file, you can also review this related article:

This is important because a poorly documented test loses part of its clinical, legal, and administrative value.

The relationship between instruments, regularization, and CONASAMA compliance

Instruments are also an important part of the regularization and professionalization process of a center.

They help to:

• Demonstrate that formal clinical evaluation exists
• Justify treatment decisions
• Support observations within the file
• Show real clinical structure during supervision

If you are working on strengthening or regularizing a center, you should also review this guide:

Understanding evaluation, file, and regulation as a single system completely changes the program's level.

How to take this to a more professional clinical level

The difference is not just knowing what test exists.

The difference is knowing:

• When to apply it
• What its result means
• What to do clinically with that result
• How to use it to structure intervention, follow-up, and continuity

When a center masters this, it stops working by intuition and begins to work with a much more solid clinical logic.

If you want to delve deeper into how to apply this in the daily practice of a counselor, you can also review this practical guide:

Essential Manual of Addiction Counseling – Practical Clinical Guide

This type of structure is what truly helps to convert instruments, interviews, and observations into useful clinical decisions.

What a center that uses instruments correctly looks like

A center that uses these instruments well:

• Evaluates from admission
• Detects comorbidities more clearly
• Measures progress objectively
• Documents in the clinical file
• Justifies treatment changes
• Has greater clinical consistency among professionals

In contrast, a center that does not use instruments or uses them only as a formality:

• Works by intuition
• Does not measure real progress
• Does not detect anxiety or depression well
• Does not support clinical decisions
• Loses technical strength and credibility

Direct impact on treatment outcomes

When these instruments are implemented correctly, there are real benefits:

• Improved diagnosis
• Greater clinical accuracy
• Better follow-up
• Greater ability to detect risk
• Better communication with families and clinical team
• Greater professionalization of the center

This not only helps with compliance or supervision. It also improves the quality of treatment the patient receives.

Frequently asked questions

Are all these instruments mandatory?

Not necessarily all of them. The important thing is that the center uses standardized, relevant, and clinically useful instruments to assess substance use and associated symptoms.

What is the indispensable minimum?

As a practical basis, a center should consider at least:

• ASSIST
• BDI or PHQ-9
• BAI or GAD-7

And if it wants a broader evaluation, adding SCL-90-R and DASS-21 can greatly strengthen the process.

How often should they be applied?

A practical recommendation is to apply them at admission, follow-up every 4 weeks, and discharge, although this can be adjusted according to program type, length of stay, and clinical needs.

Can several instruments be combined?

Yes. In fact, it is most advisable to combine tools according to need: one for substance use, one for depression, one for anxiety, and a global assessment if the case requires it.

Are they only for compliance with supervision?

No. They serve primarily to improve the clinical quality of treatment. Compliance is a consequence, not the main objective.

Conclusion

The use of assessment instruments is not a minor detail or an unimportant administrative requirement.

It is one of the clearest differences between an improvised center and a clinically structured center.

If you want to comply with CONASAMA, you need standardized evaluation.

If you want to elevate your center's level, you need to integrate these instruments strategically, interpret them correctly, and link them to the clinical file and treatment plan.

That's where professionalization truly begins.

And when that happens, you're no longer working solely with perception. You're working with structure, data, and clinical judgment.
