Schizotypal traits in Swedish speaking psychiatric patients and non-psychiatric controls.

Introduction: Recently, schizotypal personality traits were measured in a multinational sample recruited from 14 countries, however no Scandinavian cohort was included. The aim of this study was, therefore, to measure schizotypal personality traits in Swedish-speaking populations, with and without psychiatric disorders, and to investigate the psychometric properties of the Swedish version of the Schizotypal Personality Questionnaire-Brief (SPQ-B).Methods: The SPQ-B results from 50 psychiatric patients were compared to controls (n = 202). An additional sample of 25 controls completed the full SPQ twice and we calculated test-retest reliability for SPQ and SPQ-B. We estimated the internal consistency for SPQ-B and SPQ-B factors with omega. We compared the results of SPQ-B (M and SD) in patient and control groups to corresponding results worldwide.Results: We found similarity between our SPQ-B scores and those from other published samples. SPQ-B showed good internal consistency and acceptable test-retest correlations. The results indicate that the Swedish version of the instrument is valid and can differentiate psychiatric cohorts from non-psychiatric controls.Conclusion: The Swedish version of the SPQ-B exhibit good psychometric properties and is useful for assessing schizotypal traits in clinical and non-clinical populations.

Reward sensitivity, affective neuroscience personality, symptoms of attention-deficit/hyperactivity disorder, and TPH2-703G/T (rs4570625) genotype.

OBJECTIVE: Reward sensitivity is an increasingly used construct in psychiatry, yet its possible inner structure and relationship with other affective variables are not well known. METHODS: A reward sensitivity measurement scale was constructed on the basis of large item pool collected from birth cohort representative samples (the Estonian Children Personality Behaviour and Health Study; original n = 1238). Affective Neuroscience Personality Scale (ANPS) and the Adult Attention deficit hyperactivity disorder (ADHD) Self-Report Scale (ASRS) were administered in young adulthood. A variant (rs4570625) of the gene encoding tryptophan hydroxylase 2 (TPH2) that is responsible for the synthesis of central serotonin was genotyped. RESULTS: Reward sensitivity consisted of two orthogonal components, operationally defined as Openness to Rewards and Insatiability by Reward, that respectively characterise the striving towards multiple rewards and the strong pursuit and fixation to a particular reward. While SEEKING and PLAY (and to lower extent CARE) of the ANPS co-varied with Openness to Rewards, FEAR, SADNESS, and ANGER were related to Insatiability by Reward. The total score of ASRS was moderately correlated with Insatiability by Reward, while the association with Openness to Rewards was negligible. However, ASRS Inattention had some negative relationship with the Social Experience facet of Openness to Rewards. The T/T homozygotes for the TPH2 promoter polymorphism had lower Insatiability by Reward but not Openness to Rewards. CONCLUSIONS: Behaviours sensitive to rewards are separable to the components of variability and fixation, and these components are differentially related to affective aspects of personality, attention, and hyperactivity as well as to TPH2 genotype.

Young Schema Questionnaire - Short Form Version 3 (YSQ-S3): Preliminary validation in older adults.

OBJECTIVES: The aim of the current study was to establish the reliability and validity of one of the most used schema questionnaires, Young Schema Questionnaire Short Form Version 3 (YSQ-S3) in older adults. METHOD: 104 participants aged 60-84 years were recruited. They were administered a battery of questionnaires, including the YSQ-S3, Young-Atkinson Mode Inventory (YAMI), Germans (Personality) Screener, the Geriatric Depression Scale (GDS), The Geriatric Anxiety Inventory (GAI) and the Basic Psychological Needs Scale (BPNS). The YSQ-S3 was completed a second time by 83 participants a median of 12 days later. RESULTS: Satisfactory internal consistency reliability was found for 13 of the 18 early maladaptive schemas (EMS) of the YSQ-S3. Test-retest reliability was satisfactory for 17 of 18 EMS. Convergent validity was evident from significant correlations between the EMS of the YSQ-S3 and the vulnerable child and angry child schema modes from the YAMI. Congruent validity was evident from correlations of the majority of the EMS with the GDS, the GAI, German's (Personality) Screener and the BPNS measure. CONCLUSIONS: By and large the YSQ-S3 demonstrates internal and test re-test reliability in as well as congruent and convergent validity, in older adults. This suggests the YSQ-S3 may be of use in work establishing the utility of schema therapy in this population, and that schema therapy with older people warrants further exploration. Notwithstanding this some re-development of some EMS items appears to be required for the YSQ-S3 to be more relevant to older people.

Reliability of personality and values tests: The effects of "high stakes" selection conditions, and of four years in medical school.

This study investigated if scores on tests of personal qualities are affected by whether they will determine selection decisions ("high stakes") or not; and whether they are stable for individuals and groups across a four-year medical course. Two tests, one assessing values and one assessing components of personality, were administered either at the same time as a medical university entrance exam (first cohort; N = 216), or after entry was confirmed (second cohort; N = 142). Both cohorts took the tests again after four years of medical school. Analysis of variance was used to compare group mean scores and interactions, and correlation coefficients to measure temporal reliability. The high stakes cohort initially presented themselves in a significantly more positive light on the personality test. After four years of medical school scores on both tests changed significantly, towards more communitarian values and less empathic attitudes. Thus, personality scores were affected by both the conditions under which the initial tests were conducted and by the passage of time, but values only by the passage of time. Before and after scores were significantly correlated.

[Psychometric Evaluation of the German Version of the Semi-Structured Interview for Personality Functioning DSM-5 (STiP-5.1)]. / Psychometrische Evaluation der deutschen Version des Semistrukturierten Interviews zur Erfassung der DSM-5 Persönlichkeitsfunktionen (STiP-5.1).

BACKGROUND: The alternative model for personality disorders of the DSM-5 introduced an evidence-based, dimensional concept for the diagnosis of personality disorders. Criterion A, operationalized with the Level of Personality Functioning Scale, differentiates different levels of impairments in personality functioning. The Semi-Structured Interview for Personality Functioning DSM-5 (STiP-5.1) is a valid, reliable, and economic interview for the assessment of Criterion A. However, to date, there is no validated form of the interview in the German language. The aim of this study is the psychometric evaluation of the German version of the STiP-5.1. METHODS: The validity and reliability of the STiP-5.1 was investigated in a sample of healthy adults (n=55) and inpatients diagnosed with a mental disorder (n=55). Construct validity was evaluated by correlations with questionnaires for the assessment of structural impairment (IPO-16, OPD-SQS), and maladaptive personality traits (SCID-II-PQ). Interrater reliability was investigated in a sub-sample of healthy individuals and inpatients (n=50). RESULTS: With regard to validity, high correlations (r=0.68-0.78) between STiP-5.1- ratings and convergent self-report questionnaires were found. The sub-sample showed good interrater reliability (ICC=0.93). Interviews took 38 min. on average. CONCLUSIONS: The German version of the STiP-5.1 provides a valid, reliable and economic interview procedure for the dimensional assessment of personality functioning for research and clinical practice.

Response distortion on personality tests in applicants: comparing high-stakes to low-stakes medical settings.

The current study examined the degree to which applicants applying for medical internships distort their responses to personality tests and assessed whether this response distortion led to reduced predictive validity. The applicant sample (n = 530) completed the NEO Personality Inventory whilst applying for one of 60 positions as first-year post-graduate medical interns. Predictive validity was assessed using university grades, averaged over the entire medical degree. Applicant responses for the Big Five (i.e., neuroticism, extraversion, openness, conscientiousness, and agreeableness) and 30 facets of personality were compared to a range of normative samples where personality was measured in standard research settings including medical students, role model physicians, current interns, and standard young-adult test norms. Applicants had substantially higher scores on conscientiousness, openness, agreeableness, and extraversion and lower scores on neuroticism with an average absolute standardized difference of 1.03, when averaged over the normative samples. While current interns, medical students, and especially role model physicians do show a more socially desirable personality profile than standard test norms, applicants provided responses that were substantially more socially desirable. Of the Big Five, conscientiousness was the strongest predictor of academic performance in both applicants (r = .11) and medical students (r = .21). Findings suggest that applicants engage in substantial response distortion, and that the predictive validity of personality is modest and may be reduced in an applicant setting.

Examining the Interpersonal Nature of Criterion A of the DSM-5 Section III Alternative Model for Personality Disorders Using Bootstrapped Confidence Intervals for the Interpersonal Circumplex.

Criterion A of the alternative model of personality disorders (AMPD) involves the assessment of impairments in self and self in relation to other functioning and can be assessed using the Level of Personality Functioning Scale (LPFS). This study uses responses to a self-report version of the LPFS (AMPD-CAS) from 248 college students to examine the interpersonal implications of AMPD personality impairments using the interpersonal circumplex (IPC) as a nomological net. Results suggest that AMPD-CAS self-impairments are related to problems of low communion and interpersonal distress and do not appear to tap expected interpersonal problems of low agency. Additionally, AMPD-CAS identity is specifically associated with sensitivity to control, suggesting that individuals with diffuse identity find it aversive and intrusive when others take the lead. AMPD-CAS self in relation to other impairments are related to being too argumentative and suspicious of others, having difficulty connecting and caring for others, and finding others' affection and reliance aversive. Both self and self in relation to other AMPD-CAS impairments are related to interpersonal distress and misanthropy, suggesting they tap pathological aspects of personality functioning. These findings represent a first step toward fully examining the interpersonal nature of Criterion A impairments and provides preliminary evidence for the construct validity of AMPD-CAS scores.

Assessment of Personality Functioning in Adolescents With the LoPF-Q 12-18 Self-Report Questionnaire.

The classification of personality disorders (PDs) is in transition. The shortcomings of the categorical PD diagnoses led to the development of the Alternative Model for Personality Disorders (AMPD) in Section III of the DSM-5 regarding a dimensional differentiation of severity of personality pathology. Impairments in personality functioning are defined as a general Criterion A for PD. Inspired by the AMPD, the LoPF-Q 12-18 was developed to assess Levels of Personality Functioning (LoPF) dimensionally in adolescents from 12 to 18 years old in self-report. The questionnaire shows good scale reliabilities, good construct validity by demonstrating a systematic variation with pathology in line with theory, and a valuable clinical utility. The results suggest that the LoPF-Q 12-18 questionnaire is a clinically useful instrument to assess personality pathology in young people and that the concept of personality functioning is useful in detecting and describing central impairments of PD pathology at an early stage of development.

Measuring personality functioning in older adults: construct validity of the Severity Indices of Personality Functioning - Short Form (SIPP-SF).

OBJECTIVE: The dimensional personality disorders model in the Diagnostic and Statistical Manual (DSM)-5 section III conceptually differentiates impaired personality functioning (criterion A) from the presence of pathological traits (criterion B). This study is the first to specifically address the measurement of criterion A in older adults. Moreover, the convergent/divergent validity of criterion A and criterion B will be compared in younger and older age groups. METHOD: The Severity Indices of Personality Functioning - Short Form (SIPP-SF) was administered in older (N = 171) and younger adults (N = 210). The factorial structure was analyzed with exploratory structural equation modeling. Differences in convergent/divergent validity between personality functioning (SIPP-SF) and pathological traits (Personality Inventory for DSM-5; Dimensional Assessment of Personality Pathology-Basic Questionnaire) were examined across age groups. RESULTS: Identity Integration, Relational Capacities, Responsibility, Self-Control, and Social Concordance were corroborated as higher order domains. Although the SIPP-SF domains measured unique variation, some high correlations with pathological traits referred to overlapping constructs. Moreover, in older adults, personality functioning was more strongly related to Psychoticism, Disinhibition, Antagonism and Dissocial Behavior compared to younger adults. DISCUSSION: The SIPP-SF construct validity was demonstrated in terms of a structure of five higher order domains of personality functioning. The instrument is promising as a possible measure of impaired personality functioning in older adults. As such, it is a useful clinical tool to follow up effects of therapy on levels of personality functioning. Moreover, traits were associated with different degrees of personality functioning across age groups.

The Dysregulation Profile in middle childhood and adolescence across reporters: factor structure, measurement invariance, and links with self-harm and suicidal ideation.

Recently, a phenotype of severe dysregulation, the Dysregulation Profile (DP), has been identified. DP consists of elevated scores on the Anxious/Depressed (AD), Aggressive Behavior (AGG) and Attention Problems (AP) scales of the Child Behavior Checklist (CBCL), Teacher Report Form (TRF), or Youth Self Report (YSR). A drawback in current research is that DP has been conceptualized and operationalized in different manners and research on the factor structure of DP is lacking. Therefore, we examined the factor structure of DP across multiple reporters, measurement invariance across gender, parents, and time, as well as links between DP and self-harm and suicidal ideation. Data from a large community sample were used (N = 697), covering middle childhood (Mage = 7.90, (SD = 1.16) and adolescence (Mage = 13.93, SD = 1.14). Mothers, fathers, teachers, and youth themselves reported on children's emotional and behavioral problems using the CBCL, TRF, and YSR. Results indicated that in middle childhood and in adolescence, a bifactor model with a general factor of Dysregulation alongside three specific factors of AD, AGG, and AP fitted best, compared to a second-order or one-factor model. The model showed good fit for mother, father, teacher, and youth reports and showed invariance across gender, parents and time. Youth, mother, and father reported Dysregulation was uniquely and positively related to adolescent-reported self-harm and suicidal ideation. The DP is best conceptualized as a broad dysregulation syndrome, which exists over and above anxiety/depression, aggression, and attention problems as specific problems. The bifactor model of DP explains the uniqueness and interrelatedness of these behavioral problems and can help explaining shared and non-shared etiology factors. The exclusive link between the general dysregulation factor and adolescents' self-harm and suicidal ideation further established the clinical relevance of the bifactor model.

Personality and substance use: psychometric evaluation and validation of the Substance Use Risk Profile Scale (SURPS) in English, Irish, French, and German adolescents.

BACKGROUND: The aim of the present longitudinal study was the psychometric evaluation of the Substance Use Risk Profile Scale (SURPS). METHODS: We analyzed data from N = 2,022 adolescents aged 13 to 15 at baseline assessment and 2 years later (mean interval 2.11 years). Missing data at follow-up were imputed (N = 522). Psychometric properties of the SURPS were analyzed using confirmatory factor analysis. We examined structural as well as convergent validity with other personality measurements and drinking motives, and predictive validity for substance use at follow-up. RESULTS: The hypothesized 4-factorial structure (i.e., anxiety sensitivity, hopelessness, impulsivity [IMP], and sensation seeking [SS]) based on all 23 items resulted in acceptable fit to empirical data, acceptable internal consistencies, low to moderate test-retest reliability coefficients, as well as evidence for factorial and convergent validity. The proposed factor structure was stable for both males and females and, to lesser degree, across languages. However, only the SS and the IMP subscales of the SURPS predicted substance use outcomes at 16 years of age. CONCLUSIONS: The SURPS is unique in its specific assessment of traits related to substance use disorders as well as the resulting shortened administration time. Test-retest reliability was low to moderate and comparable to other personality scales. However, its relation to future substance use was limited to the SS and IMP subscales, which may be due to the relatively low-risk substance use pattern in the present sample.

Are implicit self-esteem measures valid for assessing individual and cultural differences?

OBJECTIVE: Our research utilized two popular theoretical conceptualizations of implicit self-esteem: 1) implicit self-esteem as a global automatic reaction to the self; and 2) implicit self-esteem as a context/domain specific construct. Under this framework, we present an extensive search for implicit self-esteem measure validity among different cultural groups (Study 1) and under several experimental manipulations (Study 2). METHOD: In Study 1, Euro-Canadians (N = 107), Asian-Canadians (N = 187), and Japanese (N = 112) completed a battery of implicit self-esteem, explicit self-esteem, and criterion measures. Included implicit self-esteem measures were either popular or provided methodological improvements upon older methods. Criterion measures were sampled from previous research on implicit self-esteem and included self-report and independent ratings. In Study 2, Americans (N = 582) completed a shorter battery of these same types of measures under either a control condition, an explicit prime meant to activate the self-concept in a particular context, or prime meant to activate self-competence related implicit attitudes. RESULTS: Across both studies, explicit self-esteem measures far outperformed implicit self-esteem measures in all cultural groups and under all experimental manipulations. CONCLUSION: Implicit self-esteem measures are not valid for individual or cross-cultural comparisons. We speculate that individuals may not form implicit associations with the self as an attitudinal object.

The Spatial Power Motivation Scale: a semi-implicit measure of situational power motivation.

We introduce a new nonverbal and unobtrusive measure to assess power motive activation, the Spatial Power Motivation Scale (SPMS). The unique features of this instrument are that it is (a) very simple and economical, (b) reliable and valid, and (c) sensitive to situational changes. Study 1 demonstrates the instrument's convergent and discriminant validity with explicit measures. Study 2 demonstrates the instrument's responsiveness to situational power motive salience: anticipating and winning competition versus losing competition and watching television. Studies 3 and 4 demonstrate that thoughts of competition result in higher power motivation specifically for individuals with a high dispositional power motive.

Assessing adult attachment across different contexts: validation of the Portuguese version of the experiences in Close Relationships-Relationship Structures questionnaire.

The Experiences in Close Relationships-Relationship Structures questionnaire (ECR-RS) is one of the most recent measures of adult attachment. This instrument provides a contextual assessment of attachment-related anxiety and avoidance by measuring these dimensions in various close relationships (mother, father, partner, friend). To further explore its psychometric properties and cross-cultural adequacy, this study presents the validation of the ECR-RS in a sample of Portuguese community individuals (N = 236). The Portuguese version showed adequate reliability and construct validity. The original 2-factor structure was confirmed through confirmatory factor analysis. The ECR-RS is a psychometrically robust measure of attachment, representing an important advance in the measurement of adult attachment.

Correction for faking in self-report personality tests.

Faking is a common problem in testing with self-report personality tests, especially in high-stakes situations. A possible way to correct for it is statistical control on the basis of social desirability scales. Two such scales were developed and applied in the present paper. It was stressed that the statistical models of faking need to be adapted to different properties of the personality scales, since such scales correlate with faking to different extents. In four empirical studies of self-report personality tests, correction for faking was investigated. One of the studies was experimental, and asked participants to fake or to be honest. In the other studies, job or school applicants were investigated. It was found that the approach to correct for effects of faking in self-report personality tests advocated in the paper removed a large share of the effects, about 90%. It was found in one study that faking varied as a function of degree of how important the consequences of test results could be expected to be, more high-stakes situations being associated with more faking. The latter finding is incompatible with the claim that social desirability scales measure a general personality trait. It is concluded that faking can be measured and that correction for faking, based on such measures, can be expected to remove about 90% of its effects.

Conceptualizing schizotypal ambivalence: factor structure and its relationships.

Ambivalence is an important facet of pathology that has received limited attention despite its importance in understanding negative emotionality within schizophrenia spectrum disorders. Central to understanding the role of ambivalence in schizophrenia is characterizing its manifestation within schizotypal individuals-those with the purported genetic liability for schizophrenia. The present study used the Schizotypal Ambivalence Scale (SAS) to examine the nature of ambivalence. An exploratory factor analysis of SAS scores revealed three factors: interpersonal, indecision, and contradictory feelings of ambivalence. Group differences in SAS scores were found such that psychometrically defined schizotypal individuals reported higher levels of ambivalence than controls, and different schizotypy traits exhibited different relationships with SAS factors and quality of life. The inclusion of implicit and explicit measures of positive and negative attitudes revealed that individuals with schizotypy might lack insight into their affective experiences as suggested by the incongruence between our explicit and implicit measures of social attitudes. As hypothesized, the Schizotypal Personality Questionnaire trait dimensions associated with greater SAS ambivalence and the different trait dimensions of schizotypy showed both common and disparate relationships with the ambivalence factors. The current results support the notion that schizotypal ambivalence is a multifaceted construct that not only is affective but also reflects broader processes that dynamically interact with one another to influence functional outcomes.

Construct and incremental validity of the Rotter Incomplete Sentences Blank in adult psychiatric outpatients.

The expression of positive vs negative attitudes in response to the 40 stems of the Rotter Incomplete Sentences Blank (RISB) can be scored and summed to an Overall Adjustment Score (OAS). By extending the validation of the OAS to adult psychiatric outpatients, this study demonstrates for the first time the incremental validity of a personality test over a simple self-rating. The RISB and six tests of adjustment were administered to 41 recent admissions to psychotherapy in two rural clinics. The tests of adjustment were selected to cover the two domains of symptoms vs function and the three methods of interview schedule vs objective inventory vs therapist ratings. Their scores were combined into an adjustment composite. The OAS related strongly to the composite in univariate regression, and moderately in hierarchical regression after covarying demographics, intelligence, social desirability, and self-ratings of adjustment. Construct validity was good, and incremental validity at least fair.

Sensitivity and specificity of a brief personality screening instrument in predicting future substance use, emotional, and behavioral problems: 18-month predictive validity of the Substance Use Risk Profile Scale.

BACKGROUND: This study assessed the validity, sensitivity, and specificity of the Substance Use Risk Profile Scale (SURPS), a measure of personality risk factors for substance use and other behavioral problems in adolescence. METHODS: The concurrent and predictive validity of the SURPS was tested in a sample of 1,162 adolescents (mean age: 13.7 years) using linear and logistic regressions, while its sensitivity and specificity were examined using the receiver operating characteristics curve analyses. RESULTS: Concurrent and predictive validity tests showed that all 4 brief scales-hopelessness (H), anxiety sensitivity (AS), impulsivity (IMP), and sensation seeking (SS)-were related, in theoretically expected ways, to measures of substance use and other behavioral and emotional problems. Results also showed that when using the 4 SURPS subscales to identify adolescents "at risk," one can identify a high number of those who developed problems (high sensitivity scores ranging from 72 to 91%). And, as predicted, because each scale is related to specific substance and mental health problems, good specificity was obtained when using the individual personality subscales (e.g., most adolescents identified at high risk by the IMP scale developed conduct or drug use problems within the next 18 months [a high specificity score of 70 to 80%]). CONCLUSIONS: The SURPS is a valuable tool for identifying adolescents at high risk for substance misuse and other emotional and behavioral problems. Implications of findings for the use of this measure in future research and prevention interventions are discussed.

Validation of the FFM PD count technique for screening personality pathology in later middle-aged and older adults.

Research on the applicability of the five factor model (FFM) to capture personality pathology coincided with the development of a FFM personality disorder (PD) count technique, which has been validated in adolescent, young, and middle-aged samples. This study extends the literature by validating this technique in an older sample. Five alternative FFM PD counts based upon the Revised NEO Personality Inventory (NEO PI-R) are computed and evaluated in terms of both convergent and divergent validity with the Assessment of DSM-IV Personality Disorders Questionnaire (shortly ADP-IV; DSM-IV, Diagnostic and Statistical Manual of Mental Disorders - Fourth edition). For the best working count for each PD normative data are presented, from which cut-off scores are derived. The validity of these cut-offs and their usefulness as a screening tool is tested against both a categorical (i.e., the DSM-IV - Text Revision), and a dimensional (i.e., the Dimensional Assessment of Personality Pathology; DAPP) measure of personality pathology. All but the Antisocial and Obsessive-Compulsive counts exhibited adequate convergent and divergent validity, supporting the use of this method in older adults. Using the ADP-IV and the DAPP - Short Form as validation criteria, results corroborate the use of the FFM PD count technique to screen for PDs in older adults, in particular for the Paranoid, Borderline, Histrionic, Avoidant, and Dependent PDs. Given the age-neutrality of the NEO PI-R and the considerable lack of valid personality assessment tools, current findings appear to be promising for the assessment of pathology in older adults.

[Development of the Japanese Optimism and Pessimism Scale: reliability and validity].

This study reports about the construction of a bidimensional measure of optimism and pessimism (defined as positive and negative outcome expectancies), called the Japanese Optimism and Pessimism Scale (J-OPS), and examines its reliability and validity. The participants were college students. The results revealed the following: (a) the J-OPS had sufficient reliability and validity, (b) optimism and pessimism were bidimensional in structure, (c) the general pattern of correlations with external criteria of psychological well-being (positive and negative affectivity). After controlling for optimism and pessimism respectively, it indicated that these two constructs were partially independent of each other. Namely, optimism, but not pessimism, was found to be a consistent predictor of positive affectivity (psychological well-being), whereas pessimism, but not optimism, was found to be a predictor of negative affectivity (psychological distress).
