When several psychological symptoms overlap, identifying the right diagnosis is not always straightforward. Difficulty concentrating, low mood, anxiety, sleep problems, emotional changes, or problems with daily functioning can occur for many different reasons. Sometimes more than one condition is involved.
A diagnostic evaluation provides a structured way to look beyond individual symptoms and understand the larger pattern. For adults, adolescents, and families seeking clarity in Chicago, a comprehensive psychological evaluation can help identify what may be contributing to current difficulties and what additional support may be appropriate.
What Is a Diagnostic Evaluation?
A diagnostic evaluation is a comprehensive assessment used to understand psychological symptoms, patterns of functioning, and possible mental health conditions.
Rather than asking only, “What symptoms are present?” the evaluation considers questions such as:
- When did the difficulties begin?
- How frequently do they occur?
- How do they affect work, school, relationships, or daily life?
- Are symptoms connected to a particular situation?
- Could another condition explain some of the same symptoms?
- Are multiple conditions occurring at the same time?
This broader perspective is especially important when symptoms do not fit neatly into one diagnostic category.
When Is Diagnostic Clarification Helpful?
Diagnostic clarification may be useful when an existing diagnosis does not fully explain someone’s experience or when several possible explanations need to be considered.
For example, difficulty concentrating could occur with ADHD, anxiety, depression, sleep problems, stress, or other conditions. Similarly, irritability, changes in motivation, or emotional distress can appear across several psychological conditions.
A thorough evaluation can help distinguish between these possibilities rather than assuming that the most obvious symptom represents the complete diagnosis.
Calm Grounding Psychological Services provides diagnostic clarification services for individuals who need a more detailed understanding of their psychological functioning.
What Happens During a Psychological Evaluation?
The exact psychological evaluation process depends on the referral question. A comprehensive assessment may include several components.
Clinical Interview
The psychologist gathers information about current concerns, personal history, development, relationships, education, work, medical factors, and previous mental health treatment.
Standardized Testing
Depending on the concerns, standardized psychological,personality or cognitive measures may be used to examine areas such as mood, personality, attention, memory, reasoning, or other aspects of functioning.
Behavioral and Functional Information
Symptoms are considered in the context of everyday life. For example, an adult may report being able to concentrate well on preferred activities but struggling significantly with routine work responsibilities.
Review of Existing Information
Previous evaluations, treatment history, educational records, or other relevant information may provide useful context when available.

Why Differential Diagnosis Matters
Differential diagnosis means considering multiple possible explanations for a person’s symptoms before reaching a clinical conclusion.
This matters because psychological symptoms rarely belong exclusively to one condition.
For example, imagine an adult experiencing poor concentration, fatigue, low motivation, and difficulty completing tasks. These symptoms could potentially be associated with depression, anxiety, ADHD, sleep difficulties, stress, or a combination of factors. Looking at the symptoms alone may not provide enough information.
A comprehensive evaluation examines the timing, severity, context, developmental history, and functional impact of these concerns.
The goal is not simply to find a diagnosis. It is to develop the most accurate understanding possible of the person’s difficulties.
Can Someone Have More Than One Condition?
Yes. Co-occurring conditions are common enough that clinicians need to consider whether more than one psychological condition may be affecting functioning.
For example, someone may have ADHD alongside anxiety or depression. Treating only one part of the picture may leave other difficulties unexplained.
This is particularly relevant when symptoms have changed over time or when previous treatment has not fully addressed the person’s concerns.
Calm Grounding Psychological Services also provides focused services related to ADHD assessment and other psychological concerns, depending on the individual’s needs.
Who May Benefit From a Comprehensive Evaluation?
A diagnostic evaluation may be appropriate for an adult or adolescent who:
- Has symptoms that are difficult to explain
- Has received different or conflicting diagnoses
- Experiences several overlapping psychological concerns
- Wants clarification before beginning or changing treatment
- Has longstanding difficulties affecting work, school, or relationships
- Suspects ADHD, anxiety, depression, or another condition but is uncertain
- Needs a clearer understanding of strengths and challenges
The purpose of assessment should always be connected to a specific clinical question. More testing is not automatically better; the evaluation should focus on information that can meaningfully answer the concerns being addressed.
What Happens After the Evaluation?
A psychological assessment should lead to greater clarity, not simply a list of test scores.
Depending on the findings, recommendations may address treatment, additional assessment, coping strategies, educational or workplace needs, or referral to another healthcare professional when appropriate.
The results can also help explain why certain difficulties occur and identify areas of functioning that may be strengths.

FAQ
The purpose is to develop a clearer understanding of psychological symptoms, functioning, and possible diagnoses. It can help distinguish between overlapping conditions and identify whether more than one condition may be present.
No. Therapy primarily focuses on addressing psychological concerns and developing strategies for change. A diagnostic evaluation focuses on assessment, clarification, and understanding the factors contributing to a person’s difficulties.
The length varies depending on the questions being addressed, the number and type of measures needed, and the complexity of the individual’s concerns. A focused assessment may require less time than a comprehensive evaluation.
Yes. An evaluation can consider whether symptoms are better explained by one condition, multiple co-occurring conditions, or factors that do not fit a particular diagnosis.
Yes. Adults may seek assessment when psychological symptoms, attention concerns, emotional difficulties, or longstanding patterns of functioning require greater clarification.
An existing diagnosis does not necessarily mean another evaluation is unnecessary. If symptoms have changed, the diagnosis is uncertain, or current difficulties are not fully explained, diagnostic clarification may provide additional information.
If available, bring relevant previous evaluation reports, treatment information, medication history, educational records, or other documents that may help establish the history of your concerns. Your psychologist can explain what information is most useful for your specific assessment.
