Schizoid personality disorder: a synthesis of developmental, dynamic, and descriptive features.

Various views of schizoid personality disorder in descriptive psychiatry, psychoanalysis, DSM-III and DSM-III-R are reviewed and synthesized to develop a composite picture of the syndrome. The disorder is seen as consisting of characteristic deficits in six areas of psychosocial functioning: (1) self-concept, (2) interpersonal relations, (3) social adaptation, (4) ethics, standards and ideals, (5) love and sexuality, and (6) cognitive style. Such a view maintains historical continuity in the use of the term "schizoid," combines descriptive and psychodynamic observations and correlates the behavioral and psychostructural aspects of the schizoid pathology. The paper also identifies guidelines for distinguishing the schizoid personality from other personality disorders as well as areas needing continued research.

A comparative study of paranoid and schizoid personality disorders.

OBJECTIVE: Family studies have demonstrated a higher rate of schizoid personality in the families of probands with schizophrenia and a higher rate of paranoid personality in the families of probands with delusional disorder. The authors sought to investigate the familial characteristics of probands with schizoid and paranoid personality disorders and to delineate the clinical characteristics of the two groups. METHOD: Records of 351 inpatients with discharge diagnoses that included the term "schizoid personality" or "paranoid personality" were examined to identify patients who met DSM-III-R criteria for schizoid personality disorder (N = 34) or paranoid personality disorder (N = 19). Comparisons were made between the two groups with respect to clinical symptoms, familial characteristics, and longitudinal course. RESULTS: The authors found that probands with schizoid personality disorder were hospitalized at an earlier age than probands with paranoid personality disorder, had more intervention before the index admission, and had greater morbidity following the index admission. They also found that descriptors of the two syndromes tended to congregate in the respective family material, but the differences were not statistically significant. Differences in the familial prevalence of schizophrenia were also not statistically significant. CONCLUSIONS: These familial data do not support the hypothesis that schizophrenia congregates in the families of probands with schizoid personality disorder. Possible explanations for this finding are discussed.

Treatment outlines for paranoid, schizotypal and schizoid personality disorders. The Quality Assurance Project.

Treatment outlines for paranoid, schizotypal and schizoid personality disorders were developed by having nominated experts consider their own views in the light of the treatment literature and the responses of practising psychiatrists. In the detailed recommendations it is clear that while patients with all three disorders often present for treatment in a crisis and often see no issue other than the resolution of the crisis, patients with schizoid personality disorder can use long-term psychotherapy to develop and change to the extent of no longer being handicapped.

Lifelong eccentricity and social isolation. II: Asperger's syndrome or schizoid personality disorder?

Several scales are described for measuring aspects of eccentricity and social isolation; in particular, for assessing schizoid and schizotypal personality and for rating abnormal non-verbal expression. The latter is shown to be reliable, and the former to have a measure of validity. There was an association between schizoid personality traits and abnormalities of speech and non-verbal expression. However, abnormal non-verbal expression, but not schizoid personality traits or DSM-III schizotypal personality disorder, was particularly likely to occur in those subjects who had evidence of neurological deficit, and childhood symptoms indicative of developmental disorder. Abnormal non-verbal expression, but not personality disorder, was also associated with other characteristic features of Asperger's syndrome, such as unusual, 'special' interests. It is suggested that Asperger's syndrome is a distinct syndrome from either schizoid or schizotypal personality disorder, but may be a risk factor for the development of schizoid personality disorder.

Schizoid personality disorder after prenatal exposure to famine.

OBJECTIVE: The authors tested whether early prenatal exposure to famine was associated with schizophrenia spectrum personality disorder in addition to being associated with schizophrenia per se as shown in a previous study. METHOD: The risk of schizoid personality disorder, as defined by ICD-6 to ICD-9, in men at age 18 years was compared in birth cohorts that were conceived at the height of the Dutch Hunger Winter famine and in unexposed birth cohorts of 1944-1946 in the famine region of Holland. RESULTS: The exposed cohort had a significantly greater risk (relative risk = 2.01) of schizoid personality disorder. CONCLUSIONS: Prenatal nutritional deficiency was associated with a greater risk of schizoid personality disorder in men at age 18 years.

Low body weight in male children and adolescents with schizoid personality disorder or Asperger's disorder.

This study explored the hypothesis that body weight is reduced in male children and adolescents with schizoid personality disorder or Asperger's disorder. The body weights of 33 consecutively admitted male subjects with one of these disorders were retrospectively assessed with percentiles for the body mass index (BMI). The mean percentile (+/- SD) for the BMI was 31.6 +/- 27.6 and differed significantly from the expected value of 50 (P<0.001). Ten subjects had a BMI of < or = 10th age percentile. Post hoc comparisons revealed that BMI percentiles were (a) reduced to a similar extent in patients with schizoid personality disorder and Asperger's disorder and (b) reduced to a greater extent in patients with abnormal eating behaviour. During childhood and adolescence both diagnoses are associated with an increased risk of being underweight. Population-based BMI percentiles are useful for detecting associations between specific psychopathological syndromes and body weight.

Antisocial personality--diagnosis or moral judgment?

Antisocial personality is a problem-filled diagnosis. Even when diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (DSM) II manual, it was replete with value laden terminology. DSM III makes repeated criminal behavior central and includes a list of other behaviors that do not always truly imply an antisocial personality. In order to test the possibility that factors other than those listed in the manual may often influence the diagnosis, the prevalence of required characteristics in patients diagnosed antisocial personality was compared with the prevalence of required characteristics in another personality disorder, schizoid personality. The study involved a hospitalized Veteran's Administration (VA) population, employing DSM II criteria, which was used by the VA at that time. The difference was statistically highly significant. Examination of the case histories suggests that dislike of the patients or negative moral judgments about their actions frequently were involved in making a diagnosis of antisocial personality. It is therefore crucial that moral judgments not be disguised as scientific ones, and the meaning of an antisocial personality diagnosis as utilized by clinicians needs to be seriously questioned.

The differential diagnosis of impaired reciprocal social interaction in children: a review of disorders.

Impairment in reciprocal social interaction in children that is less severe than autism can be difficult to diagnose due to the variety of developmental pathways that may lead to this problem. Seven childhood disorders are reviewed that include impaired reciprocal interaction: multisystem developmental disorder, nonverbal learning disability syndrome, semantic-pragmatic disorder, attachment disorders (including a developmental theory of limbic system damage), multiplex developmental disorder, schizoid personality disorder, and pervasive developmental disorder not otherwise specified. Clarification is needed for most of the disorders in the areas of operationalized criteria, assessment tools, and documenting causal relationships.

The role of personality disorder in 'difficult to reach' patients with depression: findings from the ODIN study.

Individuals with personality disorders (especially paranoid personality disorder) tend to be reluctant to engage in treatment. This paper aimed to elucidate the role of personality disorder in predicting engagement with psychological treatment for depression. The Outcomes of Depression International Network (ODIN) involves six urban and three rural study sites throughout Europe at which cases of depression were identified through a two-stage community survey. One patient in seven who was offered psychological treatment for depression had a comorbid diagnosis of personality disorder (most commonly paranoid personality disorder). Forty-five percent of patients who were offered psychological treatment for depression did not complete treatment. The odds of completion were higher for patients with a comorbid diagnosis of personality disorder, especially paranoid, anxious or dependent personality disorder. The relatively low number of cases with some specific personality disorders (e.g. schizoid personality disorder) limited the study's power to reach conclusions about these specific disorders. This study focused on a community-based sample which may lead to apparently lower rates of engagement when compared to studies based on treatment-seeking populations. Episodes of depression in the context of personality disorder may represent a valuable opportunity to engage with patients who might otherwise resist engagement.

A retrospective data analysis of the impact of the New York triplicate prescription program on benzodiazepine use in medicaid patients with chronic psychiatric and neurologic disorders.

BACKGROUND: Benzodiazepines are treatment mainstays for several disorders, but there is often concern about dependency and addiction. In January 1989, New York implemented regulations requiring physicians to order benzodiazepines using state-monitored triplicate prescription forms. OBJECTIVE: The purpose of this study was to assess the effects of the triplicate prescription program (TPP) on changes in use of benzodiazepines and other psychoactive drugs in clinically vulnerable Medicaid populations. METHODS: Using an interrupted time series with comparison series design, psychoactive medication use was examined in the New York (intervention) and New Jersey (control) Medicaid programs before and after implementation of the New York benzodiazepine TPP among community-dwelling Medicaid beneficiaries aged >/=19 years continuously enrolled from January 1988 through December 1990 in New York or New Jersey with diagnoses of schizophrenia, schizophreniform disorder, schizoaffective disorder, schizoid personality disorder, or schizotypal personality disorder; bipolar disorder; epilepsy; and/or panic disorder, agoraphobia without history of panic disorder, social phobia, or specific phobia. RESULTS: A total of 125,837 New York and 139,405 New Jersey Medicaid beneficiaries were continuously enrolled and met the study inclusion criteria. Of these, there were 6054 Medicaid enrollees in New York and 6875 enrollees in New Jersey who were clinically vulnerable patients with >/=1 of the specified diagnoses. New York Medicaid patients with any of these diagnoses experienced a -48.1% relative change (95% CI, -50.0% to -46.2%) in benzodiazepine use at 6 months after TPP implementation, with no decline in use in New Jersey patients. The largest reduction in benzodiazepine use was seen among patients with seizure disorder (-59.9% at 6 months; 95% CI, -63.9% to -55.9%). Although use of substitute drugs increased slightly in New York after the TPP, it did not offset reductions in benzodiazepine use. The effects of TPP were sustained for 7 years of follow-up and had the greatest impact on nonproblematic benzodiazepine use. CONCLUSIONS: During the time period studied in this analysis, the New York TPP reduced benzodiazepine use among chronically ill patients for whom these agents represent effective treatment. Our findings suggest that many patients previously receiving benzodiazepines did not receive any pharmacologic intervention.

The heritability of cluster A personality disorders assessed by both personal interview and questionnaire.

BACKGROUND: Personality disorders (PDs) as assessed by questionnaires and personal interviews are heritable. However, we know neither how much unreliability of measurement impacts on heritability estimates nor whether the genetic and environmental risk factors assessed by these two methods are the same. We wish to know whether the same set of PD vulnerability factors are assessed by these two methods. METHOD: A total of 3334 young adult twin pairs from the Norwegian Institute of Public Health Twin Panel (NIPHTP) completed a questionnaire containing 91 PD items. One to 6 years later, 1386 of these pairs were interviewed with the Structured Interview for DSM-IV Personality (SIDP-IV). Self-report items predicting interview results were selected by regression. Measurement models were fitted using Mx. RESULTS: In the best-fit models, the latent liabilities to paranoid personality disorder (PPD), schizoid personality disorder (SPD) and schizotypal personality disorder (STPD) were all highly heritable with no evidence of shared environmental effects. For PPD and STPD, only unique environmental effects were specific to the interview measure whereas both environmental and genetic effects were found to be specific to the questionnaire assessment. For SPD, the best-fit model contained genetic and environmental effects specific to both forms of assessment. CONCLUSIONS: The latent liabilities to the cluster A PDs are highly heritable but are assessed by current methods with only moderate reliability. The personal interviews assessed the genetic risk for the latent trait with excellent specificity for PPD and STPD and good specificity for SPD. However, for all three PDs, the questionnaires were less specific, also indexing an independent set of genetic risk factors.

Interpersonal disorder in schizoid and avoidant personality disorders: an attachment perspective.

OBJECTIVE: To investigate the characteristics related to avoidant attachment of 13 schizoid/avoidant psychiatric outpatients and 20 nonschizoid/avoidant psychiatric outpatients. METHOD: Three scales ("maintains distance in relationships", "high priority on self-sufficiency" and "attachment relationship is a threat to security") differentiated schizoid and avoidant personality disordered patients from other personality disordered patients. RESULTS: The results are discussed in terms of the attachment and DSM diagnostic models of avoidant styles in relationships. CONCLUSION: The 2 groups of schizoid and avoidant personality disordered patients were not significantly different on the desire for close affectional bonds scale.

The DSM-III Distinction between schizoid and avoidant personality disorders.

The DSM-III distinction between schizoid and avoidant personality disorders is examined. This distinction derives from Millon's bio-social learning theory and his interpretation of Kretschmer's personality types. Kretschmer's depiction of schizoid personality emphasizes the ratio between hyperaesthetic and anaesthetic tendencies. It is argued, therefore, that the division of this continuous distribution into two distinct personality disorders is historically inaccurate. Clinical case material is used to illustrate this misconception.
