Psychology: Psychological Disorders and the DSM Worksheet

Question 1

In your own words, explain the main purpose of the DSM in psychology and psychiatry.

Accepted Answer

The DSM is used to classify and describe mental disorders so clinicians and researchers can use shared criteria and communicate more consistently.

Question 2

The DSM lists symptoms and criteria for disorders. Explain why a symptom checklist alone is not enough to fully understand a person’s mental health.

Accepted Answer

A symptom checklist is not enough because clinicians also need to consider distress, impairment, duration, context, culture, medical factors, and the person’s life situation.

Question 3

Define clinically significant distress or impairment. Give one school, work, or relationship example.

Accepted Answer

Clinically significant distress or impairment means symptoms cause serious suffering or interfere with important areas of life. For example, anxiety may be impairing if a student repeatedly misses school because of panic symptoms.

Question 4

A student feels nervous before a major test, studies late, and has trouble sleeping the night before. Explain why this situation alone would usually not be enough to identify a psychological disorder.

Accepted Answer

This situation alone would usually not be enough because temporary stress before an important test can be a normal reaction and may not show ongoing distress, impairment, or a pattern that meets DSM criteria.

Question 5

Compare reliability and validity in the context of DSM diagnoses.

Accepted Answer

Reliability means different clinicians using the DSM should reach similar conclusions when given the same information. Validity means the diagnosis accurately represents a real and meaningful pattern of symptoms, causes, course, or treatment response.

Question 6

Explain why cultural context matters when evaluating whether a behavior is part of a psychological disorder.

Accepted Answer

Cultural context matters because beliefs, emotional expression, communication styles, and expected behavior can differ across cultures. A behavior should not be labeled disordered simply because it is unfamiliar to the clinician.

Question 7

The DSM uses categories, such as depressive disorders and anxiety disorders. Describe one advantage and one limitation of using categories.

Accepted Answer

One advantage is that categories help professionals communicate clearly and choose appropriate research or treatment approaches. One limitation is that people’s symptoms may not fit neatly into one category or may vary in severity.

Question 8

What is comorbidity, and why can it make diagnosis more complex?

Accepted Answer

Comorbidity means a person meets criteria for more than one disorder at the same time. It can make diagnosis more complex because symptoms may overlap, interact, or have different possible explanations.

Question 9

Read the scenario: Jordan has felt sad most days for two weeks after moving to a new city. Jordan still attends school, talks with friends online, and enjoys soccer practice. List two additional types of information a clinician would need before considering a DSM diagnosis.

Accepted Answer

A clinician would need more information about the severity of Jordan’s symptoms, changes in sleep or appetite, thoughts of self-harm, level of impairment, duration over time, medical causes, substance use, and cultural or life context.

Question 10

Explain differential diagnosis and give a simple example of why it is important.

Accepted Answer

Differential diagnosis means comparing possible explanations for symptoms before deciding which diagnosis best fits. It is important because trouble concentrating could be related to anxiety, depression, ADHD, sleep problems, substance use, or a medical condition.

Question 11

Why should people avoid using DSM labels casually, such as calling someone OCD because they like a clean desk?

Accepted Answer

People should avoid casual DSM labels because they can spread misinformation, minimize real disorders, and increase stigma. A preference for neatness is not the same as having a disorder that causes significant distress or impairment.

Question 12

Describe how the DSM can be useful for research on psychological disorders.

Accepted Answer

The DSM can be useful for research because it provides common definitions that help researchers identify similar groups of participants, compare findings, and study patterns such as symptoms, risk factors, and treatment outcomes.

Question 13

Some critics argue that DSM diagnoses can lead to labeling or stigma. Explain this concern and give one way a clinician can reduce the risk.

Accepted Answer

The concern is that a diagnosis may cause others to see a person only as a label rather than as a whole person. A clinician can reduce this risk by using respectful language, explaining that diagnoses are tools, and focusing on strengths as well as symptoms.

Question 14

Use the biopsychosocial model to explain why two people with similar DSM symptoms might need different supports.

Accepted Answer

Two people with similar symptoms might need different supports because biological factors, thoughts and emotions, family relationships, culture, stress, school demands, and access to care can all affect what is most helpful for each person.

Question 15

A chart shows that diagnoses of a certain disorder increased over 20 years. Explain two possible reasons for the increase that do not automatically mean the disorder became more common.

Accepted Answer

The increase could be due to greater public awareness, changes in DSM criteria, better screening, improved access to mental health care, reduced stigma, or changes in reporting practices. These factors can raise diagnosis rates without proving that the disorder itself became more common.
