The current study sought to replicate a study by Hunter et al. (2014) in which psychometrically identified schizotypes (SZTs) were distinguished from a matched comparison (COM) sample using the MMPI-2-RF. Participants were 126 pairs of SZT and COM individuals. Results showed significant mean T-score differences between these two groups across a var...

Sixty-plus years of research have demonstrated that college students tend to score significantly higher than older adults on the MMPI and MMPI-2. Relatively little research has examined whether this pattern of results holds with the newer MMPI-2-RF. The present study compared MMPI-2-RF scores of college students, both by gender and combined, to a r...

This study investigates the extent to which the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) profiles of 52 individuals making up a psychometrically identified schizotypes (SZT) sample could be successfully discriminated from the protocols of 52 individuals in a matched comparison (MC) sample. Replication analyses wer...

Introduction: Previous research has examined relationships between combat exposure and post-traumatic stress disorder. Less is known about associations between PTSD and long term health consequences of PTSD and other psychological factors on health-related quality of life (HRQOL). Methods: We carried out secondary data analyses using 2248 Vietnam...

Season of birth and hand preference were examined in a sample of 42 (7 males, 35 females) individuals who were identified as schizotypic based on their scores on selected scales of the Chapman Psychosis Proneness Scales (CPPS) and a matched comparison sample of 42 individuals with non-deviant CPPS scores. Presence or absence of schizotypy was analy...

Objective: To explore the psychometric properties of MMPI-adapted versions of the MMPI-2-RF's RC and factor scales when applied to archival adolescent MMPI data. Method: We explored the internal consistency, temporal stability, and convergent and criterion validity of newly derived MMPI-adapted RC scales and MMPI-adapted higher-order factors (MMPI-...

Construct drift (Nichols, 2006) describes the possibility that the MMPI-2 Reconstructed Clinical (RC) scales are less accurate measures of the primary traits than the original Clinical scales. The authors review the development of RC scales RC4, RC7, and RC9 and provide further evidence that these scales measure traits and behaviors that are not ne...

A subset of members of the Hathaway and Monachesi (1953, 1961, 1963) normative adolescent MMPI dataset was examined to find MMPI scales that predict the future onset of schizophrenia or adult psychopathy. The sample consisted of 23 individuals who later developed schizophrenia, 30 individuals who later developed psychopathy, and their matched contr...

Research into psychosis proneness has established the Chapman Psychosis Proneness Scales (CPPS), certain personality disorders, certain response patterns on the MMPI-2, and social withdrawal as being valid indicators of liability. The current study extends our understanding of premorbid indicators of schizophrenia-related psychosis (SRP) by examini...

McNulty, Harkness, Ben-Porath and Williams recently developed Personality Psychopathology Five (PSY-5) scales for the Minnesota Multiphasic Personality Inventory-A (MMPI-A). This study examined these new scales in a sample of 545 adolescents receiving inpatient psychiatric treatment. Item-level principal components analyses were employed to determi...

The roles of genetic and environmental influences on stressful life events were examined in 3938 twin pairs (MZ, same-sex DZ, and opposite-sex DZ) using a sex-limitation model. Life events were assessed by personal interview, and were categorized as being either personal (i.e., events that occur directly to the individual) or network (i.e., events...

The current study investigates the extent to which the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) profiles of 196 male adolescents evaluated in a South Carolina detention center could be successfully discriminated from the protocols of 200 male adolescent psychiatric inpatients in three states and 151 dually diagnosed male adol...

We examined the psychometric properties and construct validity for a Minnesota Multiphasic Personality Inventory-2 Schizophrenia Proneness (SzP) scale (Bolinskey et al., 2001) and provided normative statistics. Premorbid participants were offspring of parents with schizophrenia-related illness (SRI), with comparison groups of offspring of parents w...

The Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) Structural Summary was developed as a means of simplifying the interpretation of the 69 scales and subscales of this test instrument by organizing findings around eight primary factor dimensions. The current study examined the scale-level factor structure of the MMPI-A in a large s...

A large body of research indicates that the liability to develop schizophrenia is largely genetically mediated, although phenotypic expression requires environmental triggers/insults and/or epigenetic and/or stochastic factors. In an effort to identify the precise environmental factors that precipitate a predisposition to schizophrenia, researchers...
