Which of the following best describes tangentiality?

A. Micromanages others. Individuals with obsessive-compulsive personality disorder (OCPD) exhibit excessive control and perfectionism, often micromanaging tasks and people to ensure everything is done "correctly." They struggle with delegating responsibilities because they believe others will not meet their high standards.

B. Perfectionist. Rigid perfectionism is a core feature of OCPD. Individuals set unrealistically high expectations for themselves and others, leading to chronic dissatisfaction, procrastination, and inefficiency because they fear making mistakes.

C. Workaholic. Those with OCPD are often preoccupied with work and productivity, sometimes neglecting personal relationships and leisure activities. They may prioritize tasks over social interactions, believing that relaxation is a sign of laziness.

D. Wants to be alone. Unlike schizoid personality disorder, individuals with OCPD do not prefer isolation. They often engage with others in structured environments but struggle in relationships due to their rigid expectations, stubbornness, and excessive control over details rather than a genuine desire to be alone.

A. Hallucinations are a core positive symptom of schizophrenia and involve false sensory perceptions without an external stimulus (e.g., hearing voices, seeing things that are not there). According to the DSM-5, hallucinations are one of the three essential symptoms that must be present for a diagnosis.

B. Delusions are fixed, false beliefs that persist despite evidence to the contrary (e.g., persecutory delusions, grandiose delusions). Delusions are a hallmark symptom of schizophrenia and are required as a diagnostic criterion if present.

C. Disorganized speech reflects disorganized thinking, a key symptom of schizophrenia. It includes incoherence, tangentiality, and word salad, demonstrating the cognitive dysfunction associated with the disorder. If disorganized speech is present, it fulfils one of the primary diagnostic criteria.

D. Negative symptoms such as avolition, anhedonia, alogia, and flat affect, are common in schizophrenia but are not required for diagnosis. According to the DSM-5, at least one of the following three symptoms hallucinations, delusions, or disorganized speech must be present to meet the diagnostic criteria for schizophrenia.
