Factor Structure of the Teacher Strengths and Difficulties Questionnaire in a Large Community-Based Sample: An Investigation of Alternative Measurement Models.

The Strengths and Difficulties Questionnaire (SDQ) is a screening measure commonly used to assess behavioral and emotional symptoms and strengths among children and adolescents. However, despite its frequent use, its underlying factor structure remains an important area of inquiry. Whereas the original five-factor structure has often been supported through exploratory factor analysis, results from confirmatory analyses continue to yield mixed results.

A Brief Mindfulness-Based Intervention (bMBI) to Reduce Teacher Stress and Burnout.

Teacher stress and burnout contribute to attrition and stress-related health concerns. Despite some positive effects, previous mindfulness-based interventions (MBI) have failed to incorporate key elements of methodological rigor and have included large dosages despite research suggesting that such dosages are iatrogenic. The current study demonstrates the efficacy of a brief MBI (bMBI; four sessions, six total hours) to reduce self-reported stress, burnout, and depression, and suggests the bMBI can protect against deleterious impacts to physiological functioning.

The Relation Between Early Adolescent Physical Activity and Internalizing Problems: Variations in Exercise Motivations as a Critical Moderator.

Inconsistencies exist regarding the relation between physical activity (PA) and internalizing symptomology in early adolescence, and there is need for investigation of potential moderators that may account for these discrepancies. The current study utilized a Self-Determination Theory Framework to investigate the main effects of five key motivations to exercise and their moderating effects between PA and internalizing problems in an underserved sample of adolescents ( = 167; mean age = 12.19 years; 73% African American).

Staggered bilateral total knee arthroplasty performed four to seven days apart during a single hospitalization.

Background: The purpose of this study was to evaluate the types and prevalence of complications associated with bilateral total knee replacement performed four to seven days apart during a single hospitalization and to compare them with those associated with bilateral knee replacement performed sequentially under the same anesthetic session or staged unilateral replacements performed during separate hospitalizations.

Methods: Using a computerized database and medical records, we retrospectively evaluated 332 consecutive patients who underwent bilateral total knee replacement performed by two surgeons. A total of 241 patients underwent staggered bilateral knee replacement with the procedures performed four to seven days apart during one hospitalization, twenty-six underwent sequential bilateral total knee replacement, and sixty-five underwent staged bilateral knee replacement performed during two separate hospitalizations.
