relationships or good social skills cannot manipulate a youth's gender or ethnicity. However, the studies that highlight these characteristics as important antecedents can be used to identify groups that may be at most risk for not having close relationships or good social skills. These characteristics may need to be addressed in the design of a program geared toward a specific subgroup. Throughout this paper, our aim is to go beyond the broad identification of which factors appear to be linked to social skills and competencies, to the identification of specific strategies (the kinds of programs and activities within these programs) that have been attempted and evaluated, and/or for which there is evidence that initiating programs with these activities has the potential to contribute to improved social competency. Due to the rigorous criteria we set for our selected literature review, we may not have identified all programs and activities across the country that may be effective in promoting these skills. This point is especially pertinent for the research based on adolescents. Compared to adults, and even to younger children, there is a relative dearth of high quality research for adolescents. WHAT ARE THE ANTECEDENTS OF SOCIAL RELATIONSHIPS? Social relationships are crucial aspects of individuals' lives. This is certainly true for adolescents. This section of the chapter addresses the antecedents of quality social relationships. This section is divided into domains: family relationships and non-family relationships. The family relationships that are discussed include parents, siblings, and grandparents/other family members. The non-family relationships include other adults and peers, such as an adolescent's best friend and dating partner. As mentioned above, quality social relationships and good social skills are interrelated. Often different studies find these factors to be antecedents for each other. Family Relationships Parents development programs and even mentoring programs may enhance the quality of the parentyouth relationship. A number of antecedents have been documented for a quality parent-youth relationship. However, it is important to emphasize that many of these studies are cross-sectional, and some are longitudinal in design. These study designs make it impossible to determine the direction of causation between the variables we have characterized as antecedents of parent-youth relationships and the relationship, itself. Siblings Research has revealed a number of antecedents related to the development of conflict resolution skills. These findings should be interpreted with some prudence, however, as the studies which generated them were mostly cross-sectional or longitudinal in nature. As stated before, the only kind of study that can determine an actual casual relationship is that of experimental design. However, certain experimental evaluations of the skills-training programs provide strong evidence on this topic: adolescents who lack the skills necessary to negotiate conflict can attain them thr...
