The Relationship Between the Amount of Television Watched and the Reading Achievement Scores of Fourth, Fifth, and Sixth Grade Students
… and sixth grade students when intelligence was partialled out. To implement the study 172 students in a small rural school district within a twenty-five mile of Springfield, Missouri were selected to participate. The subjects kept a daily record of their tele-viewing time for a specified ten-day …

Theory of mind development and executive functioning in elementary school children
… second-order theory of mind tasks were obtained. Partial correlations of the measures controlling for age revealed verbal ability to be significantly correlated with theory of mind comprehension. A regression analysis demonstrated that auditory language comprehension was the only variable, in …

The Construct Validity of Self-Reported Historical Physical Activity
… through 1985. Data analysis included Spearman correlations, partial correlations, ANOVA, and ANCOVA. Results indicated self-reported historical WRJ can be assessed with reasonable validity when compared with concurrently measured treadmill performance, and there is no decay in the accuracy of …

Effect of group discussions on employee attitudes toward the aged
… of job position, and location as covariates. Partial correlations were computed and tested to determine the relation of age to attitude, tenure to attitude, education level to attitude, type of job position to attitude, and location to attitude. The findings indicated that the discussion …

Investigating the Relationship Between Defense Mechanisms and the Therapeutic Alliance in Dialectical Behaviour Therapy for Borderline Personality Disorder
… and Symptom Checklist-90-Revised (SCL-90-R). Partial correlations showed lower ODF was associated with greater rupture salience, specifically withdrawal ruptures. Regression analyses revealed ODF moderated the relationship between rupture salience and repair effectiveness, and mature defenses …

Children's Word-Finding Test (Revised): Diagnostic utility, developmental influences, and construct dimensions in a heterogeneous clinic-referred sample.
… had been utilized in previous research. Using partial correlations to control for age effects, the data of the 361 clinic-referred children were subjected to Principal Components Analysis, which generated a 3-factor solution accounting for 55% of the total variance. Correlations between the …

Three essays on econometrics: Network estimators with applications and assessment of the effects of Covid-19 pandemic
… it is possible to derive a weighted network of partial correlations. Three estimators are proposed and their performances are compared using simulations by looking at two performance measures, F1-score and Frobenius distance. They use elastic net penalty to shrink, possibly to 0, the parameters …

THE CONTRIBUTION OF PHYSICAL ACTIVITY TO NEUROIMAGING INDICES AND COGNITIVE FUNCTION IN HEART FAILURE
… medical history and self-report questionnaires. Partial correlations revealed that greater physical activity was associated with greater WMH (r(79) = .26, p = .02), but did not correlate with MTA (r(79) = .07, p = .56). Hierarchical linear regressions indicated that greater physical activity …

A Critical Examination of the Relationship between Student Performances on Assessments of English Language Proficiency and Academic Achievement
… for measurement, classification, and prediction. Partial correlations, multiple regressions, t-tests, and ANOVA analyses were performed on district level data for 1059 elementary 1st – 5th grade native Spanish speaking students who took both assessments in 2010. The results confirm that when …

20M Sprint Capacity Test, a component of the Wheelchair Sports Performance Test : A Smartwheel ® Technology Field Validation Pilot Study
… speed, athlete classification (i.e., class) was partialed out to control for this relationship. When partial correlations were analyzed, push length and speed were no longer significantly correlated (r = .175, p = .532). Push frequency and speed (m/s) remained significantly correlated (r = .573, …

The Structure and Utility of Social Desirability Scales in Psychological Research
… rather than a single construct. In Phase 2, partial correlation and regression techniques were used to examine the utility of SD scales in statistically controlling SDR. Reports of personal attributes were matched with objective, non-self report criteria when possible. The analyses provided …

Interconnections among self-awareness constructs in schizotypy: The importance of interoceptive sensibility
… insight, introspective accuracy, and schizotypy. Partial correlations found higher interoceptive sensibility was associated with lower alexithymia and lower schizotypy. Network analysis revealed that three interoceptive subscales, Body Listening, Self-Regulation, and Attention Regulation, as well …
