RESUMEN
Short empirically-supported scales or individual items are preferred in comprehensive surveys, brief screeners, and experience sampling studies. To that end, we examined the Short Almost Perfect Scale (SAPS) to evaluate empirical support for the interchangeability of items to measure perfectionistic strivings (Standards) and perfectionistic concerns (Discrepancy). Based on a large and diverse sample (N = 1,103) and tests of tau-equivalence (equal factor loadings) for each respective set of items, Study 1 advanced a subset of SAPS items to measure Standards (2 items) and Discrepancy (3 items). Cross-sectional gender and race/ethnicity invariance were supported, and in structural equations analyses, the SAPS5 factors were significantly associated with depression, state anxiety, life satisfaction, and gratitude. Study 2 cross-validated Study 1 measurement and structural findings with a new U.S. sample (N = 803). The three items representing the Discrepancy (perfectionistic concerns) factor also were supported in a cross-national comparison between the U.S. sample and a scale development sample in New Zealand (N = 3,921). For the most part, across both studies and all analyses, the three Discrepancy items were empirically interchangeable indicators of perfectionistic concerns and comparably strong predictors of psychological outcomes, supporting their use in studies or other contexts with space or time restrictions for measurement.

The current study explored the intelligibility and acceptability ratings of dysarthric speakers with African American English (AAE) and General American English (GAE) dialects by listeners who identify as GAE or AAE speakers, as well as listener ability to identify dialect in dysarthric speech. Eighty-six listeners rated the intelligibility and acceptability of sentences extracted from a passage read by speakers with dysarthria. Samples were used from the Atlanta Motor Speech Disorders Corpus and ratings were collected via self-report. The listeners identified speaker dialect in a forced-choice format. Listeners self-reported their dialect and exposure to AAE. AAE dialect was accurately identified in 63.43% of the the opportunities; GAE dialect was accurately identified in 70.35% of the opportunities. Listeners identifying as AAE speakers rated GAE speech as more acceptable, whereas, listeners identifying as GAE speakers rated AAE speech as more acceptable. Neither group of listeners demonstrated a difference in intelligibility ratings. Exposure to AAE had no effect on intelligibility or acceptability ratings. Listeners can identify dialect (AAE and GAE) with a better than chance degree of accuracy. One's dialect may have an effect on intelligibility and acceptability ratings. Exposure to a dialect did not affect listener ratings of intelligibility or acceptability.
RESUMEN
Teacher-student relationship quality (TSRQ) predicts academic motivation (Wentzel, 1997), school engagement, and academic achievement (Hughes, 2011). However, TSRQ appears to differ across demographics. For example, boys and racially/ethnically minoritized students consistently have poorer relationships with their teachers than girls and White students (Koomen & Jellesma, 2015; Murray et al., 2008). Ensuring that TSRQ is consistently conceptualized across individuals will allow demographic differences on TSRQ to be compared. The present study aims to further validate a survey instrument used to measure TSRQ, called the Inventory of Teacher-Student Relationships (IT-SR; Murray & Zvoch, 2011). Participants included 3,541 middle and high school students in a large school district in the Southeastern United States. The results of the study confirmed the hypothesized three-factor structure of the instrument. The instrument demonstrated configural, metric, and scalar invariance across race/ethnicity (Black/African American, White, Hispanic/Latinx, and multiracial) and partial metric and scalar invariance across gender (boys and girls) and school level (middle school and high school). Significant latent mean differences were found, where boys, Black/African American students, Hispanic/Latinx students, and high school students reported lower scores on various factors on the IT-SR compared to girls, White students, multiracial students, and middle school students, respectively. Results support future research and applied use of the IT-SR with middle and high school students. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
RESUMEN
Intrapersonal perfectionism is the dispositional tendency to impose perfectionistic expectations on oneself and is considered a bidimensional construct that consists of standards perfectionism and discrepancy perfectionism. Although scholars established the links between standards perfectionism and psychological adjustment and between discrepancy perfectionism and psychopathology, the mechanisms that explain these associations remain relatively unknown. Thus, a better understanding of these mechanisms, especially in children, is warranted given their high prevalence in this developmental population and potential destructiveness on psychological well-being. The present study examined whether social skills with peers mediated the link between the dimensions of interpersonal perfectionism and psychological outcomes due to the salience of social skills acquisition in middle childhood. The study included 225 students (nfemale = 114; nmale = 111) with ages ranging from 7 to 10 years at Time 1 (T1; Mage = 8.55, SD = 1.15) and from 8 to 11 years at Time 2 (T2; Mage = 9.52, SD = 1.10). Participants provided responses on measures concerning standards perfectionism, discrepancy perfectionism, social skills, and psychological well-being at both time points. Longitudinal structural equation modeling indicated that standards perfectionism was positively associated with increases in social skills over time and psychological well-being, whereas discrepancy perfectionism was linked with decreases in social skills over time followed by psychological maladjustment. The study discusses implications for interventions and treatments.

Hypertension affects more than one billion people worldwide. Here we identify 113 novel loci, reporting a total of 2,103 independent genetic signals (P < 5 × 10-8) from the largest single-stage blood pressure (BP) genome-wide association study to date (n = 1,028,980 European individuals). These associations explain more than 60% of single nucleotide polymorphism-based BP heritability. Comparing top versus bottom deciles of polygenic risk scores (PRSs) reveals clinically meaningful differences in BP (16.9 mmHg systolic BP, 95% CI, 15.5-18.2 mmHg, P = 2.22 × 10-126) and more than a sevenfold higher odds of hypertension risk (odds ratio, 7.33; 95% CI, 5.54-9.70; P = 4.13 × 10-44) in an independent dataset. Adding PRS into hypertension-prediction models increased the area under the receiver operating characteristic curve (AUROC) from 0.791 (95% CI, 0.781-0.801) to 0.826 (95% CI, 0.817-0.836, ∆AUROC, 0.035, P = 1.98 × 10-34). We compare the 2,103 loci results in non-European ancestries and show significant PRS associations in a large African-American sample. Secondary analyses implicate 500 genes previously unreported for BP. Our study highlights the role of increasingly large genomic studies for precision health research.
