The phenomenon of discordance between parents' and children's ratings of the child's mental health symptoms or of parenting behavior until recently has been treated as a problem of reliability. More recent work has sought to identify factors that may influence discordance, yet much remains to be learned about why informants' ratings of developmental phenomena are discordant and the meaning of such discordance. This study examined the extent to which discordance can be treated as a measure of the difference between two equally valid perceptions, and as such an indicator of the quality of the parent-adolescent relationship. One category of concordance and three patterns of discordance were derived from item-level differences in ratings of affection, control, and punitiveness provided by a diverse sample (53% female; 46% Hispanic-American, 35% African-American, 15% European-American, 4% another race/ethnicity) of 484 adolescents aged 12-20 years (M = 15.67, SD = 1.72) and their parents. Over and above adolescents' and parents' independent ratings of parenting, the discordance between these ratings was found to predict adolescent reports of anxiety and conduct disorder symptoms, as well as the quality of the parent-adolescent relationship. This was particularly true when adolescents and parents were discordant in their ratings of affection and when adolescents rated their parents higher on affection than did parents themselves. Implications of these findings and future research directions are discussed.  相似文献

Despite the salience of behavioral autonomy and independence to parent–child interactions during middle adolescence, little is known about parenting processes pertinent to youth autonomy development for Latino families. Among a diverse sample of 684 Latino-origin parent–adolescent dyads in Houston, Texas, this study examines how parents’ cultural orientations are associated directly and indirectly, through parental beliefs, with parenting practices giving youth behavioral autonomy and independence. Informed by social domain theory, the study’s parenting constructs pertain to youth behaviors in an “ambiguously personal” domain—activities that adolescents believe are up to youth to decide, but which parents might argue require parents’ supervision, knowledge, and/or decision-making. Results for latent profile analyses of parents’ cultural identity across various facets of acculturation indicate considerable cultural heterogeneity among Latino parents. Although 43 % of parents have a Latino cultural orientation, others represent Spanish-speaking/bicultural (21 %), bilingual/bicultural (15 %), English-speaking/bicultural (15 %), or US (6 %) cultural orientations. Structural equation modeling results indicate that bilingual/bicultural, English-speaking/bicultural, and US-oriented parents report less emphasis on the legitimacy of parental authority and younger age expectations for youth to engage in independent behaviors than do Latino-oriented parents. Parental beliefs endorsing youth’s behavioral independence and autonomy, in turn, are associated with less stringent parental rules (parental report), less parental supervision (parental and youth report), and more youth autonomy in decision-making (parental and youth report). Evidence thus supports the idea that the diverse cultural orientations of Latino parents in the US may result in considerable variations in parenting processes pertinent to Latino adolescents’ development.  相似文献

Framed within a relational developmental systems model, the 4-H Study of positive youth development (PYD) explored the bases and implications of thriving across much of the second decade of life. This special issue pertains to information derived from the recently completed eight waves of the 4-H Study of PYD, and presents findings about the relations between individual and contextual variables that are involved in the thriving process. This introduction briefly reviews the historical background and the theoretical frame for the 4-H Study and describes its general methodology. We provide an overview of the articles in this special issue and discuss the ways in which the articles elucidate different facets of the thriving process. In addition, we discuss the implications of this research for future scholarship and for applications aimed at improving the life chances of diverse adolescents.  相似文献

Both parents and important non-parental adults have influential roles in promoting positive youth development (PYD). Little research, however, has examined the simultaneous effects of both parents and important non-parental adults for PYD. We assessed the relationships among youth-reported parenting profiles and important non-parental adult relationships in predicting the Five Cs of PYD (competence, confidence, connection, character, and caring) in four cross-sectional waves of data from the 4-H Study of PYD (Grade 9: N = 975, 61.1 % female; Grade 10: N = 1,855, 63.4 % female; Grade 11: N = 983, 67.9 % female; Grade 12: N = 703, 69.3 % female). The results indicated the existence of latent profiles of youth-reported parenting styles based on maternal warmth, parental school involvement, and parental monitoring that were consistent with previously identified profiles (authoritative, authoritarian, permissive, and uninvolved) as well as reflecting several novel profiles (highly involved, integrative, school-focused, controlling). Parenting profile membership predicted mean differences in the Five Cs at each wave, and also moderated the relationships between the presence of an important non-parental adult and the Five Cs. In general, authoritative and highly involved parenting predicted higher levels of PYD and a higher likelihood of being connected to an important non-parental adult. We discuss the implications of these findings for future research on adult influences of youth development and for programs that involve adults in attempts to promote PYD.  相似文献

A ‘pink tide’ swept over Latin America following Hugo Chávez's 1998 election to the presidency in Venezuela, bringing to power multiple left or center-left governments. What possibilities for and obstacles to social change were presented by their having attained power through the ballot box? This question is explored through an examination of Venezuela's agrarian reform and the promotion of agroecology within it. The article paper concludes that, while the reform has been successful in providing resources to the land-poor and landless, the landed class has not passively acquiesced to this redistributive effort. Moreover, a situation of ‘dual power’ – in which parts of the government remain in the hands of the previously predominant class, while the newly powerful class gains influence in others – characterizes the Venezuelan state.  相似文献

In this article, I explore the emergent relationship between feminist media studies/cultural studies and the field of Evolutionary Psychology (EP). EP scholars increasingly conduct research on media and popular culture. At the same time, media/ted texts are increasingly marked by EP discourses. I take as my focus commercial women's online magazines produced in the UK and in Spain and accessed globally. Specifically, I explore a recurrent thread in their discussion forums: women expressing confusion, concern, disappointment, hurt and/or self-doubt, and asking for advice on discovering that their male partners consume various pornographies. A feminist poststructuralist discursive analysis is developed to explore both peer-to-peer and editorial advice on such ‘porn trouble’. I show how pseudo-scientific discourses give support to a narrative of male immutability and female adaptation in heterosexual relationships, and examine how these constructions are informed by EP accounts of sexual difference. The article offers empirical insights into the penetration of EP logics and narratives into popular culture transnationally. Advancing the notion of ‘postfeminist biologism’, my analysis contributes to feminist interrogations of EP's ongoing popularity in the face of sound, longstanding and widespread criticism of it as scientifically flawed and culturally pernicious.  相似文献
