Schizotypal Personality Questionnaire

Despite widespread use in schizophrenia-spectrum research, uncertainty remains around an empirically supported and theoretically meaningful factor structure of the Schizotypal Personality Questionnaire (SPQ). Current identified structures are limited by reliance on exclusively nonclinical samples. The current study compared factor structures of the SPQ in a sample of 335 nonpsychiatric individuals, 292 schizotypy-spectrum individuals (schizophrenia, schizoaffective disorder, or schizotypal personality disorder), and the combined group (N = 627). Unidimensional, correlated, and hierarchical models were assessed in addition to a bifactor model, wherein subscales load simultaneously onto a general factor and a specific factor. The best-fitting model across samples was a two-specific factor bifactor model, consistent with the nine symptom dimensions of schizotypy as primarily a direct manifestation of a unitary construct. Such findings, for the first time demonstrated in a clinical sample, have broad implications for transdiagnostic approaches, including reifying schizotypy as a construct underlying diverse manifestations of phenomenology across a wide range of severity.

Career adaptability is an important resource for dealing with career transitions such as the transition from university to work. Previous research emphasized the importance of focusing on career adapt-abilities instead only on general career adaptability. The aim of this research was to investigate whether career adaptability can be conceptualized as a bifactor model and whether general and specific dimensions of career adaptability have a relationship with job-search self-efficacy of graduates. In an online cross-sectional study, 667 graduates completed the Career Adapt-Abilities Scale and Job Search Skill and Confidence Scale. The CFA analysis showed that the bifactor model of career adaptability had a good fit where general factor explained most of the items’ variance. The SEM analysis revealed that general career adaptability and the specific factor of confidence positively correlated with job-search and interview performance self-efficacy. Control only correlated with interview performance self-efficacy. Neither concern nor curiosity showed a significant relationship with job-search and interview performance self-efficacy.

Academic Results

Positive psychological capital (PsyCap) is the name given to a set of psychological dimensions (hope, resilience, self-efficacy, and optimism) that may support students in their effort to achieve better academic results and even improve the employability of graduates. These dimensions could help students to achieve better academic results and impact fresh graduates’ ability to stand the labour market in times of crisis. A scale, called Academic PsyCap, was specifically developed to evaluate the four PsyCap dimensions among students and fresh graduates. To deeply investigate the structural validity of the scale, three alternative models (one-factor model, correlated four-factor model, bifactor model) were run on the responses provided by about 1,600 fresh graduates at the University of Padua. The results indicated that the bifactor model fit the data better than the other two models. In this model, all items significantly loaded on both their own domain specific factor and on the general factor. The values of Percentage of Uncontaminated Correlations (PUC), Explained Common Variance (ECV), and Hierarchical Omega suggested that multidimensionality in the scale was not severe enough to disqualify the use of a total PsyCap score. The scale was found to be invariant across gender and academic degree (bachelor’s and master’s degree). Internal consistency indices were satisfactory for the four dimensions and the total scale.

Abstract Background While the Schizotypal Personality Questionnaire (SPQ; Raine, 1991) is an established measure of self-reported schizotypy, the higher-order structure of its ratings has continued to be debated in numerous translations. Here, we examined the psychometric properties of a Romanian translation of the SPQ and assessed associations with quality of life, self-esteem, and satisfaction with life. Methods In total, 711 university students (488 women, 223 men) from Romania completed a novel translation of the SPQ online alongside measures of quality of life, self-esteem, and life satisfaction. All participants indicated no immediate family history relating to psychosis. Results Using confirmatory factor analysis, we suggest that a 4-dimensional model of SPQ scores had better fit to these data than alternative 3- and 4-factor models. The 4-factor model also demonstrated partial measurement invariance across sex, although sex differences on domain scores were negligible (ηp2 = .01-.02). The 4 SPQ domains were significantly and negatively correlated with all additional measures of quality of life, self-esteem, and satisfaction with life. Further, in predicting scores on these additional measures, the Negative SPQ domain emerged as the strongest predictor, with Paranoid and Disorganised scores also significant predictors. Discussion Romanian SPQ scores demonstrated adequate construct and predictive validity vis-à-vis quality of life, satisfaction with life, and self-esteem. Importantly, our findings highlighted the benefit of a Paranoid factor within the SPQ dimensionality, which provides support for a 4-factor conceptualisation of SPQ scores in a hitherto neglected linguistic group.
