Phenotypic expression of schizotypal traits in an adolescent population.

The main goal of the present study was to examine the influence of gender and age in the phenotypic expression of schizotypal traits in a community sample of adolescents. The sample was composed of a total of 1,618 participants, 776 (48%) males, with a mean age of 15.9 years (SD = 1.

Reliability and sources of validity evidence of the Oviedo Schizotypy Assessment Questionnaire-Abbreviated (ESQUIZO-Q-A).

The main goal of this research was to examine the reliability and different sources of validity evidence of the Oviedo Schizotypy Assessment Questionnaire-Abbreviated (ESQUIZO-Q-A) in nonclinical adolescents. The final sample was made up of 1,455 participants, 705 males (48.5%), with a mean age of 15.

Relationship between schizotypal and borderline traits in college students.

The main objective of the present investigation was to analyze the relationship between self-reported schizotypal and borderline personality traits in a sample of 759 college students (M = 19.63 years; SD = 2.03).

Dimensional structure and measurement invariance of the youth self-report across gender and age.

Purpose: The aim of the present work was to examine the correlated eight-syndrome model of the Youth Self-Report (YSR) proposed by Ivanova et al [1], using a confirmatory factor analysis for ordinal data. Likewise, we explored the measurement invariance of the YSR across gender and age using multigroup comparisons, and checked whether there were differences in the latent means.

Methods: The sample was made up of 4,868 nonclinical adolescents (47.

Borderline personality traits in nonclinical young adults.

The main purpose of this study was to explore the dimensionality of the borderline personality disorder in nonclinical young adults by means of the Borderline Personality Questionnaire (BPQ; Poreh et al., 2006). We also studied the phenotypic expression of the borderline personality traits as a function of participants' gender and age, and the relationship between BPQ subscales and measures of depressive symptoms, anxiety, stress, hallucinatory predisposition, and paranoid ideation.

Measurement invariance of the Schizotypal Personality Questionnaire-Brief across gender and age.

The purpose of this study was to examine the dimensional structure and measurement invariance of the Schizotypal Personality Questionnaire-Brief (SPQ-B) (Raine and Benishay, 1995) across sex and age in a representative sample of nonclinical adolescents and young adults. The sample consisted of 1789 adolescents and young adults (42.1% males), with a mean age of 17.

Psychotic-like experiences in the adolescent general population.

Objective: The main purpose of this study was to analyze the distribution of psychotic-like experiences in nonclinical adolescents. Likewise, we studied in depth the role of gender and age in phenotypal expression of these symptoms.

Method: A total of 1438 adolescents entered the study, 691 (48.

Exploring the relationship between coping strategies and binge eating in nonclinical adolescents.

The aims of the study were to determine the rate of binge eating and examine the relationship between binge eating and coping in nonclinical adolescents. A total of 1913 adolescents completed the Bulimic Investigatory Test, Edinburgh, the Adolescent Coping Scale (ACS), the Youth Self-Report and additional questions regarding the binge-eating episodes. Of the total sample, 6.

Early psychopathological features in Spanish adolescents.

Schizotypal experiences and depressive symptoms are quite common among adolescents, and have been considered as risk markers for schizophrenia-spectrum and mood disorders. The main goal of the present study was to analyze the relationship between schizotypal experiences and depressive symptoms in a community sample of non-clinical adolescents. The sample comprised a total of 1653 participants, 794 male (48%), with an average age of 15.

Factor structure and measurement invariance of the Wisconsin Schizotypy scales across gender and age.

The Wisconsin Schizotypy Scales are among the most widely used instruments for the assessment of psychosis proneness. The main goal of the present work was to study the dimensional structure underlying the Revised Physical Anhedonia Scale (RPhA), the Revised Social Anhedonia Scale (RSAS), the Magical Ideation Scale (MIS) and the Perceptual Aberration Scale (PAS). It was also explored whether the dimensions underlying these scales were invariant across gender and age.

Symptomatic and functional outcome in youth at ultra-high risk for psychosis: a longitudinal study.

The current report assesses the clinical, functioning and demographic data of a cohort enrolled in the P3 prevention program for psychosis; a Spanish National Health System and Ministry of Science funded program. Comparisons are made between those individuals who had converted to psychosis and those who had not at 3years after an average of 24 treatment sessions. Subjects included 61 participants meeting Structured Interview for Prodromal Syndromes criteria, with ages ranging from 17 to 31, and all meeting criteria for ultra-high risk of psychosis.

Binge eating in adolescents: its relation to behavioural problems and family-meal patterns.

The aim of the study was to explore the relationship between binge eating, behavioural problems and family-meal patterns in a sample of adolescents. Two hundred and fifty-nine adolescents from a public secondary school completed the Bulimic Investigatory test, Edinburgh (BITE) [Henderson, M., & Freeman, C.

Examining the relationship between binge eating and coping strategies and the definition of binge eating in a sample of Spanish adolescents.

The present study had two major goals: to explore the relationship between binge eating and coping strategies in a sample of Spanish adolescents and to examine the adolescents' concept of binge eating. Two hundred and fifty-nine adolescents from a secondary school completed the Adolescent Coping Scale (ACS; Frydenberg & Lewis, 1993) and the Bulimic Investigatory Test, Edinburgh (BITE; Henderson & Freeman, 1987), as well as additional questions regarding the binge-eating episodes. The results show that the adolescents who reported binge eating used more avoidance coping strategies than those who did not engage in this behavior.
