You will be presented with a collection of medical randomized controlled trial (RCT) reports addressing a shared clinical question -- for instance, the efficacy of a medical intervention on a disease or condition. Given the titles and abstracts of these reports, your task is to generate the conclusion of the systematic review article synthesizing the key findings. Your conclusion should be a few sentences long. In your response, include only the conclusion and no other text. The RCT reports are below.



Title 1:
Is youth victimization related to trauma symptoms and depression after controlling for prior symptoms and family relationships? A longitudinal, prospective study.
Abstract 1:
The common finding linking symptoms such as posttraumatic stress disorder ( PTSD ) and depression with youth victimization ( e.g. , sexual abuse ) might well be artifactual if preexisting psychopathology or disturbed family relationships create a common risk for both later victimization and later symptoms . This study used a longitudinal , prospect i ve design to examine this issue . In a national r and om sample  telephone survey , children 10 to 16 years old were interviewed and then reinterviewed approximately 15 months later about  psychological problems , family relationships  and  victimization  experiences that had occurred in the interim . Victimization in the interim was associated with PTSD-related symptoms and depression measured at Time 2 , even after controlling for these symptoms and the quality of the parent-child relationship at Time 1 . The association was particularly strong for sexual abuse , parental assault , and kidnapping experiences . However , these data also suggest that some of the apparent association found in cross-sectional studies between victimization and psychopathology may be due to prior psychopathology ( but not parent-child relationship problems ) , which puts children at risk for both victimization and later symptoms
Strong evidence ( according to Community Guide rules ) showed that individual and group cognitive-behavioral therapy can decrease psychological harm among symptomatic children and adolescents exposed to trauma .
Evidence was insufficient to determine the effectiveness of  play therapy , art therapy , pharmacologic therapy , psychodynamic therapy , or  psychological debriefing  in reducing psychological harm .
