“…As noted by Kemp et al [20], college students are at an ideal age for assessing schizotypy, as they are just entering the window of risk for developing schizophrenia-spectrum symptoms and disorders. Furthermore, as demonstrated in this and other schizotypy interview studies (e.g., [26,46]), college students readily experience schizophrenia-spectrum psychopathology (as well as other forms of psychopathology). Specifically in the present study, the MSS-B subscales predicted a wide variety of symptoms and impairment, including Cluster A personality disorders, despite the fact that the study employed a young, high functioning sample.…”

The present study employed structured diagnostic interviews to assess the construct validity of the brief version of the Multidimensional Schizotypy Scale (MSS-B), which was developed to assess positive, negative, and disorganized dimensions of schizotypy. It was hypothesized that the MSS-B subscales would be associated with differential patterns of symptoms and impairment, comparable to findings for the full-length MSS. A total of 177 young adults completed structured diagnostic interviews assessing symptoms and impairment. As hypothesized, MSS-B positive schizotypy was significantly associated with interview ratings of positive (psychotic-like) symptoms, as well as schizotypal and paranoid personality disorder traits. MSS-B negative schizotypy was associated with interview ratings of negative symptoms, as well as schizoid, paranoid, and schizotypal traits. Furthermore, negative schizotypy predicted Cluster A personality disorder diagnoses. MSS-B disorganized schizotypy was associated with interview ratings of disorganized symptoms. All three schizotypy dimensions were associated with impaired functioning. This was the first study to evaluate the validity of the MSS-B using interview measures, and the pattern of findings for each MSS-B subscale was closely comparable to the findings for the full-length MSS. Contrary to our hypothesis, cannabis use was largely unassociated with psychotic-like symptoms and did not moderate the expression of the schizotypy dimensions. The MSS-B has good psychometric properties, high concordance with the full-length MSS, and good construct validity. Thus, it appears to be a promising brief alternative to traditional schizotypy measures.

“…Structured interviews provide a useful method for assessing schizotypy and evaluating the validity of schizotypy scales, although other researchers have noted the limitations of diagnostic interviews (e.g., Chmielewski et al, 2015; Samuel et al, 2011; Samuel et al, 2016). Cross-sectional and longitudinal interview studies have demonstrated the validity of the WSS (e.g., Bolinskey et al, 2017; Chapman et al, 1994; Cicero et al, 2014; Gooding et al, 2005; Kwapil, 1998), and its positive and negative schizotypy dimensions (e.g., Barrantes-Vidal et al, 2013; Gross et al, 2015; Kwapil et al, 2008; Kwapil et al, 2013; Racioppi et al, 2018). These studies demonstrated that positive schizotypy is associated with psychotic-like symptoms, schizotypal and paranoid personality traits, impaired functioning, and mood disorders and substance abuse.…”

The present study assessed the construct validity of the Multidimensional Schizotypy Scale (MSS). Specifically, it assessed the associations of the MSS positive, negative, and disorganized schizotypy subscales with interview-rated symptoms and impairment in 177 young adults. As hypothesized, the MSS positive schizotypy subscale was associated with interview-rated positive symptoms, and schizotypal and paranoid personality traits. Negative schizotypy was associated with interview-rated negative symptoms, and schizotypal and schizoid traits, and elevated rates of schizophrenia-spectrum personality disorders. Disorganized schizotypy was associated with disorganized symptoms and attentional deficits. All three subscales were associated with impaired functioning. This was the first study to evaluate the validity of the MSS using interview measures. The findings indicate that the schizotypy dimensions are associated with unique patterns of symptoms and impairment, and support the validity of the MSS.

“…There are also some related studies supporting that the Schizoid style predicts Hypochondriac Belief. Both schizoid and avoidant factors resided in the schizophrenia spectrum disorders [47], which have overlapping clinical features with each other [9], and avoidant personality disorder is often found in hypochondriasis [22, 23]. These observations indirectly point to the association between Schizoid and Hypochondriacal Belief.…”

Hypochondriac concerns and correlates of personality styles and affective states in bipolar I and II disorders

et al. 2018

BackgroundHypochondriac concerns are associated with the treatment-difficulty of bipolar disorder, which might be due to the personality styles and affective states.MethodsWe invited outpatients with bipolar I disorder (BD I, n = 87), bipolar II disorder (BD II, n = 92) and healthy volunteers (n = 129) to undergo the Illness Attitude Scales and Parker Personality Measure tests, and measurements of concurrent affective states.ResultsCompared to healthy volunteers, BD I and BD II patients scored significantly higher on mania, hypomania and depression. BD I and BD II patients also scored significantly higher on Symptom Effect and Treatment Seeking, and BD II patients scored higher on Patho-thanatophobia and Hypochondriacal Belief. BD II in addition scored higher on Patho-thanatophobia than BD I did. In controls, the Dependent style predicted Patho-thanatophobia and Symptom Effect, Schizoid with Hypochondriacal Belief; in BD I, Narcissistic (−) with Hypochondriacal Belief, Histrionic with Patho-thanatophobia and Hypochondriacal Belief, depression with Hypochondriacal Belief, and hypomania with Symptom Effect and Hypochondriacal Belief; in BD II, depression with Symptom Effect and Hypochondriacal Belief, mania with Symptom Effect.ConclusionsBipolar disorder, especially BD II, is associated with greater hypochondriac concerns, which relates to personality disorder functioning styles and concurrent affective states.
