Background: The Personal Outcomes Scale (POS) is a scale developed to measure quality of life of adults (18+) with intellectual disability. Previous studies have reported good fit for Spanish and Portuguese language versions of POS. Aims: This study aimed to evaluate the factor structure of the English language version of POS when used to measure…

Objective: The purpose of this study was to begin developing and validating an instrument to measure self-trust in adults. Method: Using a multi-phased and mixed methods approach to instrument development, the RSTI scores were tested across three samples reflecting national demographics of adults in the United States (n = 157, n = 692, n = 261).…

Several validated adult autism symptom screening tools exist; however, there are concerns about the validity of instruments in adults who self-identify and those who have an autism diagnosis. This study evaluated the psychometric properties of the RAADS-R and RAADS-14 across gender, autism diagnosis and autistic identity, and age among a sample of…

Actively involving the network during treatment, as recommended in Autism Spectrum Condition (ASC) guidelines, can be facilitated with the Network in Action-Questionnaire (NiA-Q), which identifies the current and potential sources of social support. The aims of this study were to (1) examine the factor structure of the NiA-Q and (2) to explore the…

This study aimed to validate the Learned Helplessness Questionnaire (LHQ), originally developed in Italy, for use in an American context. It examined the LHQ's factor structure, social desirability bias, the relationship between learned helplessness and mastery orientation, and demographic differences in these constructs. Data from 100 adults were…

Fluency confound (FC) has been a widely studied issue in divergent thinking (DT) tasks. In this study, the impact of DT task structure on FC was examined by focusing on activity level data from Torrance Tests of Creative Thinking (TTCT)-Figural. The TTCT-Figural involves two different task structures. Prompts in Activities 1 and 2 are designed for…

Emotion dysregulation is common among autistic people, yet few measures have received psychometric evaluation in this population. We examined the factor structure, reliability, and validity of a commonly-used measure of emotion dysregulation, the "Difficulties with Emotion Regulation Scale" ("DERS"), in a sample of 156 autistic…

Worry is a phenomenon that is present in multiple psychopathologies. Given the widely accepted transdiagnostic role that worry plays in psychopathology, reliable measures for this construct are pivotal for clinical practice. The Penn State Worry Questionnaire (PSWQ) is one of the most widely used and established measures of worry in both clinical…

The Daily Life Experiences -- Frequency scale (DLE-F) measures the frequency of 18 racial discrimination experiences. Bifactor exploratory and confirmatory analyses indicated that the DLE-F is a unidimensional scale that yields valid and reliable scores. The DLE-F also showed evidence of measurement invariance by gender, convergent evidence, and…

The aim of this research is to adapt the Delay of Gratification Inventory to a Turkish adult sample. The data for the study was obtained from adults over the age of 18 between April and May 2021. The "Personal Information Form," the "Delay of Gratification Inventory," the "Psychological Well-Being Scale," and the…

The current study examined the psychometric properties and correlates of three measures assessing individual differences in mattering among people from Palestine assessed in January, 2024. This study uniquely considers mattering as a resource and feelings of not mattering as a risk factor among people experiencing traumatizing life circumstances.…

This study aimed to translate the Japanese version of the Life Skills Scale for Adolescents and Adults (LSSAA) into Chinese, English, and Korean, simplify it, and assess its reliability and validity. Validation was performed using individual data of 9941 high-school students from China, Japan, Korea, and the United States collected by the 2021…

The immediate concerns and aftereffects of parentification in the United States are well documented. However, the correlates of parentification in international communities are less known. This psychometric study explored the validity of a Swahili version of the Parentification Inventory (PI; Hooper, 2009) with a sample of 279 Kenyan adults.…

We aimed to refine the previously proposed antisocial subscale for the Dimensional Clinical Personality Inventory 2 (IDCP-ASPD). The sample involved 628 Brazilian adults between 18 and 81 years old. We administered the revised ASPD subscale (IDCP-ASPD-R), the Affective and Cognitive Measure of Empathy (ACME), the Crime and Analogous Behavior Scale…

In this investigation, we examine the contribution of intrinsic content density (ICD) to measures of expository text processing. In Studies 1 and 2, the factor structure of select text density metrics was examined and refined using two text samples (Ns = 150) randomly selected from an expository text corpus. Scores on the ICD measure based on the…
