Academic socialization,parental educational expectations,and academic self‐efficacy among Latino adolescents

This study examined the direct association between parental educational expectations and adolescents’ academic self‐efficacy, as well as the moderating influence of parental academic socialization messages. Participants were 148 Latino parent–adolescent dyads with the majority of Mexican origin (80.4%). Most of the parent participants were mothers (85.8%). Adolescents were 13 (46%) or 14 (54%) years of age, and 53% identified as female. Adolescents reported their academic self‐efficacy and perceptions of their parents’ educational expectations; parents reported on their academic socialization messages of shame/pressure and effort regarding academics. The results suggest that, after accounting for parents’ level of education and immigrant status, parental educational expectations were positively associated with adolescent academic self‐efficacy. This association was stronger among adolescents whose parents reported transmitting fewer messages of shame/pressure and academic effort. These results point to the importance of nuances in the content and type of academic socialization messages within Latino families.

Beyond educational attainment: The importance of skills and lifelong learning for social outcomes. Evidence for Europe from PIAAC

Empirical evidence suggests that educational attainment nurtures people's social outcomes and promotes active participation in society and stability. However, it is unclear to what extent other types of human capital also correlate with social outcomes. Hence, we explored the opportunity offered by the PIAAC survey through its provision of information on educational attainment, observed individual key skills proficiency, and participation in adult education and training (adult lifelong learning). We therefore studied the association between these human capital variables and social outcomes, and more specifically interpersonal trust and participation in volunteering activities. Results revealed that these social outcomes were affected not only by the formal qualification obtained, determined by the education variable, but also throughout the life‐cycle. Indeed, education and training when undertaken during adult life have a significant impact, especially on volunteering. The fact that the skill proficiency also plays a significant role is extremely relevant, as skills are more likely to change over the life‐cycle, either in a positive or negative way. Whilst the formal education received is constant after exiting the educational system, skills reflect competences more accurately: first, because those with the same level of education may have different skill levels because of differences in the quality of education or ability; second, because skills can vary over time. For example, they may increase with work experience or informal education, or decrease as a result of depreciation and ageing. These findings suggest that social outcomes are prone to be affected by many factors other than formal education, suggesting that policy makers can implement recommendations even after formal education has been completed.

Adjustment scales for preschool intervention: Extending validity and relevance across multiple perspectives

A series of studies extended psychometric research on the Adjustment Scales for Preschool Intervention (ASPI). The ASPI is a multidimensional measure of preschool emotional and behavioral adjustment for use within formal early childhood educational programs. These studies used a multiple method, multisource approach to provide additional evidence for the reliability and validity of the ASPI. Findings documented inter‐rater reliability of the ASPI across key informants within early childhood educational programs—teachers and teacher assistants. Findings supported concurrent validity of the ASPI with direct observations of preschool classroom adjustment problems and the developmentally salient constructs of temperament and emotion regulation. Implications for policy, practice, and future research are discussed. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 725–736, 2004.
