Video modeling with other as model (VMO) is a more practical method for implementing video-based modeling techniques, such as video self-modeling, which requires significantly more editing. Despite this, identification of contextual factors such as participant characteristics and targeted outcomes that moderate the effectiveness of VMO has not…

Meta-analysis has become a popular tool to statistically integrate results across studies in order to formulate more general conclusions on treatment effectiveness. Unfortunately, traditional meta-analytic applications fail to answer the question whether enough cumulative knowledge is available to draw convincing statistical conclusions. Leaving…

This effectiveness study examined the course of treatment longitudinally and outcomes associated with psychodynamic psychotherapy for a sample of 1,050 people undertaking this treatment in a community setting, over the course of 4 years, at 3-month intervals, using the Outcome Questionnaire (OQ)-45.2. The authors used multilevel modeling to look…

This study examined the relationships among statistics achievement and four components of attitudes toward statistics (Cognitive Competence, Affect, Value, and Difficulty) as assessed by the SATS. Meta-analysis results revealed that the size of relationships differed by the geographical region in which the studies were conducted as well as by the…
