Test: Types of Psychological Disorders - Question 3

What is the most likely diagnosis in a 24-year-old man who avoids a job he really wants because of an intense fear that he will be humiliated or rejected when meeting unfamiliar people?

Detailed Solution for Test: Types of Psychological Disorders - Question 3

Social anxiety disorder is the correct answer. The fear is judged to be out of proportion to the actual risk of the social interactions and is causing significant impairment in occupational functioning, which is concerning for social phobia. Social anxiety disorder should be suspected when intense fear of social interactions, in which the individual may be scrutinized by others, is out of proportion to the actual threat of the social situation and causes significant impairment in important areas of functioning, and the fear is not better explained by some other mental disorder.

Test: Types of Psychological Disorders - Question 4

While completing a ritual, such as the repeated locking and unlocking of the front door, an individual with obsessive-compulsive disorder would most likely feel which of the following?

Detailed Solution for Test: Types of Psychological Disorders - Question 4

People with obsessive-compulsive disorder often feel the need to perform certain rituals or routines repeatedly. These individuals are often compelled by intrusive thoughts. An individual compelled to perform repeated behavior, such as continually locking and unlocking a door, will often feel distressed by these intrusive thoughts and the need to perform certain behaviors. Someone with obsessive-compulsive disorder cannot simply feel dismissive toward these thoughts, which is part of the distress they experience. While performing these rituals can sometimes cause a temporary sense of relief, this relief does not last for the rest of the day. It is only a transient sense of relief that may come from temporarily satisfying the intrusive thoughts. An individual compelled to perform repeated behavior would have no particular reason to feel content or relaxed.

Test: Types of Psychological Disorders - Question 6

Below is a list of factors that may increase the chances of developing Post Traumatic Stress Disorder (PTSD). Which of these are likely to be factors?
I. Childhood neglect or abuse
II. Being threatened with a weapon
III. Witnessing traumatic events, such as death and killing
IV. Lacking a good support system
V. Having an on-going persistent chronic condition, such as heart disease or diabetes

Detailed Solution for Test: Types of Psychological Disorders - Question 6

All of these are factors that can contribute to PTSD, except for an on-going chronic physical health condition. On-going mental health conditions, such as depression and anxiety, can contribute to PTSD (usually in combination with more actue problems of experiencing or witnessing trauma), and physical conditions can increase the likelihood of depression, but alone, they do not increase the likelihood of developing PTSD.

Test: Types of Psychological Disorders - Question 7

If a person were diagnosed with agoraphobia, then which of the following scenarios would best describe their behavior due to the disorder?

Detailed Solution for Test: Types of Psychological Disorders - Question 7

Agoraphobia occurs when a patient fears situations that make them feel trapped, embarrassed, or helpless. They may fear an actual event or even simply the anticipation of an event. This is more likely to occur in a crowded area, such as a subway or metro bus, than it would simply interacting with a few strangers at a given time. In other words, they may experience a lack of desire to interact with strangers to avoid embarrassment, but that is not a situation in which they would feel trapped or helpless.
