A large number of methods of factor rotation are available in the literature, but the development of formal criteria by which to compare them is an understudied field of research. One possible criterion is the Thurstonian concept of "factorial invariance", which was applied by Kaiser to the varimax rotation method in 1958 and has been subsequently neglected. In the present study, we propose two conditions for establishing whether a method satisfies factorial invariance, and we apply them to 11 orthogonal rotation methods. The results show that 3 methods do not exhibit factorial invariance under either condition, 3 are invariant under one but not the other, and 5 are invariant under both. Varimax rotation is one of the 5 methods that satisfy factorial invariance under both conditions and is the only method that satisfies the invariance condition originally advocated by Kaiser in 1958. From this perspective, it appears that varimax rotation is the method that best ensures factorial invariance.

Stigma is common in people with chronic pain. At present, however, the measurement of stigma in Spanish-speaking individuals remains a challenge due to a lack of validated measures in Spanish. The present study examines the psychometric properties of the Spanish version of the Stigma Scale for Chronic Illnesses 8-item version (SSCI-8) in people with chronic pain, focusing on dimensionality, factorial invariance, reliability (internal consistency and test-retest), and construct validity.

The Patient Health Questionnaire-9 (PHQ-9) is a widely used tool for assessing depressive symptom severity and as a screening tool in the diagnosis of major depression. Designed as both a diagnostic instrument and a severity index, it is commonly used in primary care and research. However, findings regarding its reliability and validity for these dual purposes have been mixed.

Today's increasingly brittle, anxious, nonlinear, incomprehensible world of work calls for a socially and emotionally competent workforce. However, there is a clear gap in higher education settings regarding the assessment and promotion of students' social and emotional competence (SEC). Our study aims to address the pressing need to evaluate and develop higher education students' SEC by providing a tool to assess these skills, enabling researchers and practitioners to intervene and actively promote them.

Objective: This systematic review focused on identifying and evaluating assessment tools used to measure outcomes of psychological interventions for pediatric functional neurological disorder (FND).
Method: A comprehensive search was conducted on September 24, 2024, across Web of Science, PsycINFO, and Medline. Studies were included if they involved individuals under 18 with FND diagnosis, utilized a psychological intervention, and assessed treatment outcomes using validated measures.
