Residential relocation during the early adolescent years can make numerous adaptational demands during a developmentally sensitive period. This study was conducted to determine the range and prevalence of adolescent concerns related to relocation; to assess the congruence between adolescent-reported concerns and parental perceptions of the adolescents' concerns; and to examine the relationship between congruence in this specific context and intimacy in the mother-adolescent relationship. Home-based interview and questionnaire sessions were conducted with 71 seventh- and eighth-graders and their parents. All students began the school year in a new school due to an intercommunity change in residence. Responses yielded 11 categories of concerns. The most frequently cited pre-move worry was "leaving old friends," while the adolescents' biggest struggles in September were "making new friends" and "academic achievement in the new schools." The percentage of adolescents and parents reporting each of the 11 types of difficulties was similar, suggesting that the mothers were knowledgeable about problems their teenagers were likely to encounter following relocation. However, mothers frequently failed to recognize some of their adolescent's specific concerns, and often reported concerns that their adolescent did not cite. Other findings suggest that intimacy between mothers and daughters play an important role in accruate maternal identification of their daughters' concerns during the transition. For boys, self-reported intimacy with their mothers seemed to tell little about accurate maternal identification of concerns. (NB)
