, Question 1
Simonny’s behaviour is most consistent with Schizoid Personality Disorder (SPD) as classified in the
DSM-5-TR, due to his pervasive detachment from social relationships and restricted range of
emotional expression.
Simonny’s abnormal behaviour can be classified under Schizoid Personality Disorder (SPD)
according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision
(DSM-5-TR) published by the American Psychiatric Association (2022). Schizoid Personality Disorder
is categorized under Cluster A personality disorders, which are characterized by odd or eccentric
behaviour patterns. The DSM-5-TR defines SPD as a pervasive pattern of detachment from social
relationships and a restricted range of emotional expression in interpersonal settings, beginning in
early adulthood and present across various contexts (American Psychiatric Association [APA],
2022).
Several diagnostic criteria for SPD are evident in Simonny’s case. First, individuals with SPD neither
desire nor enjoy close relationships, including being part of a family (APA, 2022). Simonny
demonstrates this through his decision to abandon the house built by his parents and his limited
communication with them, despite their emotional distress. Second, he almost always chooses
solitary activities, as seen in his preference to live alone on his grandfather’s farm and spend most
of his time farming. Third, there is little, if any, interest in sexual experiences or intimate
relationships, which aligns with Simonny’s lack of romantic relationships and absence of desire for
one (APA, 2022).
Additionally, individuals with SPD take pleasure in few activities. Although Simonny derives
pleasure from farming, this appears to be a solitary activity, consistent with the disorder’s profile.
Furthermore, he lacks close friends or confidants other than first-degree relatives and shows
emotional coldness, detachment, or flattened affectivity (APA, 2022). This is supported by reports
that he is “a man of few words,” appears emotionally blunt, and is perceived as cold and aloof by
shop cashiers. His discomfort in social situations, such as going to the shops, further supports the
pattern of social detachment.
Importantly, the DSM-5-TR requires that these behaviours are enduring, inflexible, and lead to
clinically significant impairment or distress (APA, 2022). Simonny’s long-standing social isolation,
emotional detachment, and functional impairment in social domains suggest a persistent
personality pattern rather than a temporary reaction. There is no evidence of psychotic symptoms,
mood disorder, or autism spectrum disorder that would better explain his presentation, further
supporting a diagnosis of Schizoid Personality Disorder.
In conclusion, based on the DSM-5-TR criteria and the behavioural evidence provided in the case
study, Simonny’s abnormal behaviour is best classified as Schizoid Personality Disorder,
characterized by pervasive social detachment, limited emotional expression, and preference for
solitary activities (APA, 2022).
