Situation: A 24-year-old man with schizophrenia is admitted to the psychiatric unit. He stopped taking his antipsychotic medicine 2 months ago. For weeks he has stayed in his room, has rarely bathed, and has stopped going to work. He has no history of violence. The nurse reviews the symptom groups of schizophrenia with a student. Which finding is a negative symptom?

Negative symptoms are losses or reductions of normal function: blunted affect, alogia, avolition, anhedonia, and asociality. A lack of drive to begin and complete everyday activities is avolition. Delusions, hallucinations, and disorganized speech are positive symptoms because they add to or distort normal function.

Understanding the symptom groups

Schizophrenia symptoms are conventionally divided into positive and negative clusters. Positive symptoms represent an addition or distortion of normal mental function, while negative symptoms represent a loss or reduction of normal function. In this patient, the weeks of staying in his room, rarely bathing, and stopping work point toward a decline in motivation and self-initiated behavior, which belongs to the negative symptom domain.

A lack of drive to start or finish daily tasks is termed avolition, one of the core negative symptoms of schizophrenia. Avolition reflects diminished motivation to pursue goal-directed activities, including basic self-care, work, and social engagement. The patient’s poor hygiene and withdrawal from occupational responsibilities are clinical expressions of this motivational deficit.

Key point! Negative symptoms are not simply “bad behavior” or laziness. They are a core, biologically driven dimension of schizophrenia that accounts for a large part of long-term disability and poor functional outcomes ^[2]. Because they respond poorly to available antipsychotic treatments, they remain a primary driver of functional impairment ^[1].

Why the other options are positive symptoms

Positive symptoms add experiences or behaviors that are not normally present. The remaining options all fit this category.

Option	Symptom type	Explanation
2 Fixed belief that neighbors are spying	Delusion (positive)	A fixed false belief that is added to normal thought content
3 Voice commenting on his actions	Auditory hallucination (positive)	A sensory perception without external stimulus
4 Speech jumping between unrelated ideas	Disorganized speech (positive)	Loose associations or derailment that distorts normal thought flow

Watch out! Delusions, hallucinations, and disorganized speech are all positive symptoms because they add to or distort normal function. Negative symptoms, by contrast, subtract from normal function.

The five negative symptom domains

Negative symptoms are not a single entity. They cluster into recognizable domains that clinicians assess and document .

Negative symptom	Definition	Clinical example
Avolition	Reduced drive or motivation to initiate and persist in goal-directed activity	Stops going to work, neglects bathing, stays in room
Alogia	Poverty of speech or reduced verbal output	Gives brief, empty replies; long pauses before answering
Anhedonia	Diminished ability to experience pleasure	Shows no enjoyment in activities previously found pleasurable
Asociality	Reduced social drive and withdrawal from relationships	Declines invitations, avoids family contact
Blunted affect	Diminished emotional expression in face, voice, and gestures	Flat facial expression, monotone voice, reduced eye contact

In this patient, the lack of drive to begin and complete everyday activities is specifically avolition, which is the correct answer. The poor hygiene and cessation of work are observable consequences of that motivational deficit.

Primary versus secondary negative symptoms

Negative symptoms can be primary, meaning they are an integral dimension of schizophrenia itself, or secondary, arising from other factors such as positive symptoms, depression, antipsychotic side effects, substance use, or social isolation . This distinction matters clinically because secondary negative symptoms may improve when the underlying cause is addressed, whereas primary negative symptoms tend to persist.

In this scenario, the patient stopped taking his antipsychotic 2 months ago. The worsening of negative symptoms after medication discontinuation may reflect an unmasking of primary negative symptoms, but could also be compounded by secondary factors such as social withdrawal or emerging depression. A thorough assessment is needed to differentiate these possibilities.

Key point! Negative symptoms are a core component of schizophrenia and are not simply a reaction to positive symptoms. They independently contribute to poor functional outcomes and are often the most disabling aspect of the illness ^[2].

Clinical and exam relevance

For nursing licensure examinations, the ability to classify symptoms as positive or negative is frequently tested. The mnemonic often used is that positive symptoms are “added” (hallucinations, delusions, disorganized speech, grossly disorganized behavior), while negative symptoms are “subtracted” (the five A’s: avolition, alogia, anhedonia, asociality, affective flattening).

When assessing a patient with schizophrenia, nurses should document both symptom clusters because they guide treatment priorities. Positive symptoms often respond to antipsychotic medication, while negative symptoms show limited response to current pharmacologic options and require psychosocial interventions such as social skills training, supported employment, and cognitive remediation ^[1][2]. The patient’s lack of drive to perform daily tasks is therefore not only a diagnostic clue but also a target for nursing interventions aimed at promoting function and preventing further decline.
