A guide for researchers to calculate effect sizes for single-case research using three nonoverlap methods is provided. These methods are evaluated for their strengths and limitations, applied to a data set, and contrasted with one another. Criteria are presented to determine goodness of fit between nonoverlap procedures and data sets.

Positive psychology is a useful framework to understand Latina/o students' experiences. In the current study, we examined how presence of meaning in life, search for meaning in life, hope, and family importance influenced 128 Latina/o college students' psychological grit. We used the Meaning in Life Questionnaire (MLQ), Subjective Happiness Scale, Hope Scale, Pan-Hispanic Familism Scale, and Short Grit Scale to measure the aforementioned factors. Using multiple regression analysis, findings indicated that hope and search for meaning in life were significant predictors of psychological grit. Higher levels of hope positively predicted psychological grit, while higher levels of search for meaning in life negatively predicted psychological grit. We provide a discussion regarding the importance of these findings as well as recommendations for future research.

We evaluated the effectiveness of trauma-focused cognitive behavioral therapy (TF-CBT) for treating posttraumatic stress disorder and co-occurring depression symptoms across 21 betweengroup studies representing the data of 1,860 children and adolescents (1,106 girls and 754 boys). Separate meta-analytic procedures were conducted for studies that implemented wait-list/no treatment and alternative treatment comparisons to estimate aggregated treatment effect of TF-CBT and moderators of effect size magnitude. Limitations of our findings and implications for counselors are discussed.
