Literature reports that the quality of family relationships, particularly with parents, is associated with psychopathology, namely depression, in adolescents. QRI was developed by Pierce, Sarason and Sarason (1991) and adapted to the Portuguese population by Neves and Pinheiro (2006), and the QRI-PP was created from QRI for adolescents. The present study intends to analyse the factorial structure and reliability of the Quality of Relationships Inventory -Parents Perception (QRI-PP). The sample was composed by 456 parents of adolescents with ages between 12 to 17 years. Similarly to QRI, the QRI-PP assesses the parents' perceptions of social support, depth and conflict in the relationships with their children. The aims of the study were to conduct an exploratory factor analysis, followed by a confirmatory factor analysis to identify the factorial structure of IQRI-PP. The results obtained showed that the instrument is composed by 16 items, distributed in two factors: support/depth and conflict, with adequate Cronbach's alphas, indicating that QRI-PP is a valid instrument to analyse the parents/children quality of relationships, from the perspective of parents. A bi-factorial structure was also obtained in previous researches, conducted in Portuguese population, of the father and mother versions of QRI for adolescents (Matos,

Depression is considered a health problem associated with significant impairment in psychosocial functioning. The quality of interpersonal relationships between parent and adolescents can be an important protective/vulnerability factor to depression. This study aims to understand if the psychosocial functioning of the adolescent is a moderator variable between the quality of interpersonal relationships perceived by the parents and depressive symptoms of the adolescents. Further, we analyse if gender of adolescents influence the quality of these relationships, and if psychosocial functioning and quality of interpersonal relationships is associated with depression. The sample is constituted by 132 adolescents and their parents, participants integrated in a research project about prevention of adolescent depression (PTDC/MHC-PCL/4824/2012). Self-report questionnaires were used to assess depressive symptoms (Children's Depression Inventory -CDI; Kovacs, 1985; Portuguese version: Marújo, 1994) were associated with depressive symptoms. It was found a moderation effect of school performance and satisfaction in the relationship between the support/depth dimension of the relationship parent/children and depressive symptoms. Our findings reinforce the importance of parent/children relationships and psychosocial functioning in the development of adolescent depression and emphasize the importance of the inclusion these variables in the prevention programs of depression.
