The article by Adrian Furnham, titled “A Bright Side Analysis of Subclinical Schizoid Personality Disorder: A NEO-PI-R Domain and Facet Analysis of the HDS Reserved Scale” (2020), offers a compelling examination of the interplay between normal personality traits and their extremities that may relate to schizoid personality disorder (SPD). The findings, derived from a robust sample of over 5000 British adults, add valuable insights into the dimensional aspects of personality disorders. However, some critical reflections are warranted to deepen the understanding and implications of these findings.

Firstly, Furnham’s approach to correlating the Hogan Development Survey (HDS) Reserved scale with NEO-PI-R domains and facets is methodologically sound but raises questions about the specificity of the constructs being measured. The Reserved scale, intended to measure subclinical SPD, may indeed overlap significantly with introversion and low agreeableness, as the study suggests. However, the extent to which this scale captures the unique aspects of SPD, beyond the scope of introversion alone, is debatable. The potential conflation of introversion with schizoid tendencies could lead to overpathologizing normal introversion traits, which are not inherently dysfunctional.

Secondly, while the study robustly confirms previous findings on the relationship between SPD and lower extraversion and agreeableness, it also highlights an elevated neuroticism in the Reserved individuals. This aspect is intriguing, as traditional descriptions of SPD in the DSM-5 and other clinical manuals often emphasize emotional coldness and detachment rather than neuroticism. The correlation with neuroticism facets such as self-consciousness and vulnerability suggests a possible overlap with avoidant personality traits, which could be distinctly explored in future research.

Furthermore, the interpretation of schizoid personality disorder as merely an extreme on normal personality trait continuums might simplify the complex etiology of personality disorders. While the dimensional approach to personality disorders has gained support, it is crucial to maintain a clear distinction between adaptive personality variations and maladaptive personality disorders. This distinction is vital not only for academic clarity but also for clinical practice and treatment planning.

Lastly, the implications of these findings for practical interventions remain underexplored. If traits associated with SPD (as measured by the Reserved scale) are linked with specific challenges in workplace settings, as Furnham suggests, then interventions could be tailored to help individuals harness their strengths and mitigate challenges. For example, understanding that individuals high in Reserved traits may benefit from roles requiring independence and less interpersonal interaction could guide career counseling and job design.


Furnham’s study contributes significantly to the understanding of subclinical SPD through a personality trait lens, offering a bridge between personality psychology and clinical psychopathology. However, careful consideration should be given to the implications of labeling extreme trait manifestations as pathological, especially in the context of everyday functioning and mental health stigma. Future research should continue to explore these dimensions with an emphasis on distinguishing pathological features from personality diversity to avoid the risk of overpathologizing normal behavioral variations.
