Beyond Clinical High-Risk State for Psychosis: The Network Structure of Multidimensional Psychosis Liability in Adolescents
OBJECTIVES:
The main goal of the present study was to analyze the network structure of schizotypy dimensions in a representative sample of adolescents from the general population. Moreover, the network structure between schizotypy, mental health difficulties, subjective well-being, bipolar-like experiences, suicide ideation and behavior, psychotic-like experiences, positive and negative affect, prosocial behavior, and IQ was analyzed.
METHOD:
The study was conducted in a sample of 1,506 students selected by stratified random cluster sampling. The Oviedo Schizotypy Assessment Questionnaire, the Personal Wellbeing Index-School Children, the Paykel Suicide Scale, the Mood Disorder Questionnaire, the Strengths and Difficulties Questionnaire, the Prodromal Questionnaire-Brief, the Positive and Negative Affect Schedule for Children Shortened Version, and the Matrix Reasoning Test were used.
RESULTS:
The estimated schizotypy network was interconnected. The most central nodes in terms of standardized Expected Influence (EI) were 'unusual perceptual experiences' and 'paranoid ideation'. Predictability ranged from 8.7% ('physical anhedonia') to 52.7% ('unusual perceptual experiences'). The average predictability was 36.27%, implying that substantial variability remained unexplained. For the multidimensional psychosis liability network predictability values ranged from 9% (estimated IQ) to 74.90% ('psychotic-like experiences'). The average predictability was 43.46%. The results of the stability and accuracy analysis indicated that all networks were accurately estimated.
CONCLUSIONS:
The present paper points to the value of conceptualizing psychosis liability as a dynamic complex system of interacting cognitive, emotional, behavioral, and affective characteristics. In addition, provide new insights into the nature of the relationships between schizotypy, as index of psychosis liability, and the role played by risk and protective factors.Swiss National Science Foundation (100019_159440)Europa FEDER La Rioja 2014-2020 (SRS 6FRSABC026
Evaluación adaptativa informatizada del clima organizacional
Computerized Adaptive Tests (CAT) constitutes a major advance in the field of the assessment of social sciences and health. It is interesting to incorporate this methodological development to organizational field. The objective of this research is to develop a CAT for evaluating the organizational climate. In order to do this, a bank of 160 items was constructed, which was administered to a sample of 3,163 workers (M age= 51.90 years; SD= 6.28 years). The results show that the CAT works efficiently for the three item banks used (150, 130 and 50 items). The information function shows that the latent trait in the whole range of values is measured with similar accuracy. The correlation between the scores obtained with the CAT, the three item banks and the CLIOR scale of organizational climate was higher than 0.90 in all cases (SE<0.32). With a SE< 0.32, the 150 item CAT uses a mean of 22.5 items (SD = 22.5 items). The CAT developed allows an accuracy and useful assessment of the organizational climate on organizational settings and research.Los Tests Adaptativos Informatizados (CAT) constituyen un gran avance en el campo de la evaluación de las ciencias sociales y de la salud. Es interesante incorporar este desarrollo metodológico al campo de la psicología organizacional. El objetivo de esta investigación es desarrollar un CAT para evaluar el clima organizacional. Para ello, se construyó un banco de 160 ítems, que se administró a una muestra de 3163 trabajadores (M = 51,90 años; SD = 6,28 años). Los resultados muestran que el CAT funciona de manera eficiente para los tres bancos de ítems utilizados (150, 130 y 50 artículos). La función de la información muestra que el rasgo latente se mide con una precisión similar en todo el rango de valores. La correlación entre las puntuaciones obtenidas con el CAT, los tres bancos de ítems y la escala CLIOR de clima organizacional fue superior a 0,90 en todos los casos (SE <0,32). Con una precisión fiajada en SE <0,32, el CAT de 150 ítems utiliza una media de 22,5 ítems (SD = 22,5). El CAT desarrollado permite una evaluación útil y precisa del clima organizacional en contextos organizacionales
Parental support and gender moderate the relationship between sexual orientation and suicidal behavior in adolescents
la investigación indica que las personas pertenecientes a minorías sexuales tienen un mayor riesgo de sufrir problemas de salud mental. Además, el apoyo parental podría desempeñar un papel protector. El objetivo de este estudio fue examinar, en una muestra representativa de adolescentes, si la orientación sexual estaba relacionada con un mayor riesgo de sufrir problemas de salud mental. Se analizó el posible efecto moderador del apoyo parental en la relación entre la orientación sexual y la salud mental, moderado también por el género de los participantes. Método: participaron 1790 estudiantes de secundaria. Se evaluaron indicadores de dificultades emocionales y conductuales, depresión, experiencias psicóticas, conducta suicida, bienestar y autoestima. Resultados: se encontraron efectos principales significativos de género y orientación sexual. Tener una orientación sexual diversa (es decir, lesbiana/ gay, bisexual y questioning) estaba relacionado con mayores dificultades de salud mental. Además, se encontró una interacción significativa del género y la orientación sexual en la conducta suicida. Por último, el apoyo parental y el género moderaron la relación entre la orientación sexual y la conducta suicida. Conclusiones: estos resultados ponen de manifiesto la importancia de promover la salud mental y el bienestar de los jóvenes pertenecientes a minorías sexuales.The scientific literature indicates that people from sexual minorities may be at increased risk for mental health difficulties. Moreover, parental support could play a protective role against poor mental health. The objective of this study was to examine whether a persons sexual orientation was related to a greater risk of mental health problems in a representative sample of adolescents. In addition, the study analyzed the possible moderating effect of parental support in the relationship between sexual orientation and mental health, as also moderated by participant gender. Method: The sample consisted of 1790 secondary-school students. Indicators of emotional and behavioral difficulties, symptoms of depression, psychotic-like experiences, suicidal behavior, well-being, and self-esteem were
assessed. Results: The results indicated significant main effects of gender and sexual orientation. Having a diverse sexual orientation (i.e., lesbian/gay, bisexual and questioning) was related to increased risk of mental health difficulties. Moreover, the results showed a significant interaction effect of gender and sexual orientation on suicidal behavior. Finally, the results showed the moderating effect of parental support and gender in the relationship between sexual orientation and suicidal behavior. Conclusions: These findings highlight the importance of promoting sexual minority youths mental health and well-bein
Datos perdidos y propiedades psicométricas en los tests de personalidad
The aim of this study was to analyze the influence of missing values on the psychometric properties of personality tests. An applied approach was used, trying to simulate conditions similar to those found in the professional practice. Two simulation studies were designed, based on actual data from the administration of ESQUIZO-Q test, which assesses schizotypy. In the first study a large sample was used (N=3056), and in the second one a smaller sample (N=200) was analyzed. In both cases four levels of missing values, and eight procedures for handling missing values were simulated. The influence of these conditions on the estimates of Cronbach's α, the factor structure of the test, and the arrangement of test scores were analyzed. The results suggest that in the presence of low levels of missing values, even the simplest imputation methods offer appropriate solutions from a applied point of view. From a statistical perspective the Expectation-Maximization (EM) method is the one with a better overall performance in the different criteria handled. Also noteworthy is the poor performance of replacement procedures when using the value of the previous or posterior item in order to maintain the factor structure of the data.Se investigó la influencia que tienen los valores perdidos sobre las propiedades psicométricas de los tests de personalidad. Se ha utilizado un enfoque aplicado, simulando situaciones que puedan tener relevancia cara a la práctica profesional. Se diseñaron dos estudios de simulación a partir de datos reales obtenidos de la aplicación de la prueba ESQUIZO-Q que evalúa esquizotipia. En el primero de ellos se utilizó una muestra de 3056 personas y en el segundo una de 200; en ambos casos se emplearon cuatro niveles de pérdida de respuestas y ocho procedimientos de imputación de los valores perdidos.Se estudió su influencia sobre las estimaciones del coeficiente α de Cronbach, la estructura factorial de la prueba y la ordenación de las puntuaciones en el cuestionario. Los resultados apuntan a que en presencia de niveles bajos de valores perdidos, incluso los métodos más simples, ofrecen soluciones muy razonables desde el punto de vista práctico. Desde la perspectiva más estadística el procedimiento de Expectación-Maximización (EM) es el que presenta un mejor comportamiento global en los diferentes criterios manejados. Destaca también el pobre comportamiento de los métodos de sustitución por el valor anterior o posterior de cara a mantener la estructura factorial de los datos
Latent profile analysis of psychosis liability in a community-derived sample of adolescents: Links with mental health difficulties, suicidal ideation, bipolar-like experiences and psychotic-like experiences
Experiencias psicóticas atenuadas, problemas emocionales y comportamentales y estrategias de afrontamientos en adolescentes no clínicos
Individuals who reported psychotic-like experiences (PLEs)
are at increased risk for future clinical psychotic disorders. Furthermore, those with PLES report more emotional problems and less effective coping strategies. The main goal of the present study was to compare the emotional and behavioral problems and the coping strategies used by adolescents with and without PLEs. In addition, the relationship between the emotional and behavioral problems and the coping strategies in adolescents with
PLEs was explored. A total of 1,713 nonclinical adolescents participated in the study, 832 males (48.6 %), with a mean age of 14.7 years (SD=1.7). Participants with PLEs presented a greater number of behavioral and emotional problems in comparison to those participants who did not report such experiences. Likewise, adolescents with PLEs used Avoidance coping strategies more frequently and Positive coping strategies less frequently in comparison to the adolescents without PLEs. The emotional and behavioral problems were found to be positively related to Avoidance coping and negatively related to Positive coping strategies in the adolescents with PLEs. These findings converge with data found in previous studies of both patients with schizophreniaand psychosis-prone individuals and have clear implications toward the establishment of prevention and early detection strategies in high-risk individualsIndividuos que informan de experiencias psicóticas atenuadas presentan un mayor riesgo futuro de transitar hacia los trastornos psicóticos. Además, aquellos que informan de este tipo de experiencias también presentan problemas emocionales y estrategias de afrontamiento menos efectivas. El principal objetivo de este estudio fue comparar los problemas emocionales y comportamentales y las estrategias de afrontamiento en adolescentes que informaron o no de síntomas psicóticos atenuados. También se examinó la relación entre los problemas emocionales y de comportamiento y las estrategias de afrontamiento en adolescentes que autoinformaron de experiencias alucinatorias. Un total de 1.713 adolescentes no clínicos participaron en el estudio, 832 hombres (48,6%), con una edad media de 14,7 años (DE=1,7). Los participantes con experiencias pseudopsicóticas presentaron un mayor número de problemas de conducta y emocionales en comparación con aquellos participantes que no informaron de tales experiencias. Del mismo modo, los adolescentes que informaron de esta sintomatología utilizaron estrategias de afrontamiento evitativas con mayor frecuencia y estrategias de afrontamiento positivas con menor frecuencia en comparación con los adolescentes del grupo control. Los problemas emocionales y de comportamiento se relacionaron de forma positiva con el afrontamiento evitativo y negativamente con las estrategias positivas de afrontamiento en el grupo de adolescentes con experiencias psicóticas subclínicas. Estos resultados convergen con los datos encontrados en estudios previos de pacientes con psicosis y en individuos adultos sanos con propensión de psicosis y tienen claras implicaciones hacia el establecimiento de estrategias de prevención y detección precoz en individuos de alto riesgo teórico
From high intellectual ability to genius: Profiles of perfectionism
The aim of the study was to understand the components associated with the types of perfectionism described as adaptive/healthy, maladaptive/unhealthy or non-perfectionism, which could offer positive or negative aspects to improve excellence and well-being, exploring the number and content of the latent perfectionism structure as a multidimensional construct in a sample of High Intellectual Abilities (HIA) students. Links with Positive and Negative perfectionism were also compared across perfectionism latent profiles. A total of n=137 HIA students, mean age 13.77 years (SD=1.99), participated in a survey. The Almost Perfect Scale Revised (APS-R) and Positive and Negative Perfectionism Scale-12 (PNPS-12) were used. Results obtained showed three latent classes (LC): ‘Unhealthy’ (LC1), ‘Healthy’ (LC2) and ‘No perfectionism’ (LC3). LC1 showed high scores on Discrepancy subscales but low in Order and High Standards. LC2 displayed higher scores on High Standards and Order. LC3 displayed low scores across all perfectionism facets. Statistically significant differences were found across latent profiles in almost all perfectionism features. Different patterns of associations with Positive and Negative perfectionism were obtained across latent profiles. These findings address the latent structure of perfectionisms in HIA students and allow us to delimit, analyze, and understand the tentative latent profiles within the HIA arena
