The utility of measures of child and adolescent anxiety: a meta-analytic review of the Revised Children's Manifest Anxiety Scale, the State-Trait Anxiety Inventory for Children, and the Child Behavior Checklist.

We evaluated the ability of the Revised Children's Manifest Anxiety Scale (RCMAS), the State-Trait Anxiety Inventory for Children (STAIC), and the Child Behavior Checklist (CBCL) to (a) discriminate between youth with an anxiety disorder and youth without a disorder, (b) discriminate between youth with an anxiety disorder and youth with either externalizing disorders or affective disorders, and (c) measure treatment change. In addition, variables, including age and sex, were explored as possible moderators of instrument utility. A meta-analysis of 43 articles was conducted. A large effect size was found when the instruments were used to compare youth with an anxiety disorder to youth without a disorder. When comparing anxious youth to psychiatric control groups, the picture was mixed; the instruments were found to be useful when discriminating between youth with an anxiety disorder and youth with an externalizing disorder, but not between youth with an anxiety disorder and children and adolescents with an affective disorder. The RCMAS, STAIC, and CBCL were found to be moderately sensitive to treatment gains.

Violence exposure in real-life, video games, television, movies, and the internet: is there desensitization?

It is believed that repeated exposure to real-life and to entertainment violence may alter cognitive, affective, and behavioral processes, possibly leading to desensitization. The goal of the present study was to determine if there are relationships between real-life and media violence exposure and desensitization as reflected in related characteristics. One hundred fifty fourth and fifth graders completed measures of real-life violence exposure, media violence exposure, empathy, and attitudes towards violence. Regression analyses indicated that only exposure to video game violence was associated with (lower) empathy. Both video game and movie violence exposure were associated with stronger proviolence attitudes. The active nature of playing video games, intense engagement, and the tendency to be translated into fantasy play may explain negative impact, though causality was not investigated in the present design. The samples' relatively low exposure to real-life violence may have limited the identification of relationships. Although difficult to quantify, desensitization to violence should be further studied using related characteristics as in the present study. Individual differences and causal relationships should also be examined.
