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 study informs the design and implementation of future MBIs, including strategies for reducing intervention dosages, in order to improve effectiveness and maximize cost-effectiveness.

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 (n = 167; mean age = 12.19 years; 73% African American). Analyses showed that intrinsic motivations were negatively related to internalizing problems and extrinsic motivations were positively related. PA was only protective against internalizing problems when intrinsic motivations were high and had iatrogenic effects when these were low. Exploratory analyses further delineated the unique effects of motivational orientations. Clinical implications and future research directions are discussed.

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. We analyzed data from youth in Grades K through 12 from a large epidemiologic study in the Southeastern United States. Teacher-report SDQ data were used to test three confirmatory factor models by school level (i.e., elementary [Grades K-5] and secondary [Grades 6-12]): The original five-factor model, a three-factor model, and a bifactor model. Model fit indices and reliability measures supported the original five-factor model as the preferred model when using the teacher-reported SDQ with both elementary and secondary school children. Implications for using the SDQ in applied research and predictive modeling are discussed.

The Factor Structure and Gender Invariance of ADHD Symptoms in College Students.

Previous studies examining the factor structure of attention-deficit/hyperactivity disorder (ADHD) symptoms in adults using self-report measures have shown mixed results, supporting two-, three-, and bifactor solutions. The current study further investigated the structure of ADHD symptoms in adults using the Current Symptoms Scale and rigorous model evaluation in a sample of 892 college students. Confirmatory factor analysis was used to analyze and compare five-factor structures; a single-factor model, a two-factor model, a three-factor model, and two bifactor models. A single-factor model with correlated residuals best fit the data. Factor correlations with nearly all related constructs (i.e., symptoms of oppositional defiant disorder, depression, impairment, previous ADHD diagnosis, grades, and substance use) were significant in the expected directions and the model was invariant across gender. These findings contribute to a growing body of work suggesting a unidimensional factor may best represent ADHD symptoms in adults. Implications are discussed.
