Constructing positive futures: modeling the relationship between adolescents' hopeful future expectations and intentional self regulation in predicting positive youth development.

Intentional self regulation and hopeful expectations for the future are theoretically-related constructs shown to lead to positive youth development (PYD). However, the nature of their relationship over time has not been tested. Therefore, this study explored the associations between hopeful future expectations and intentional self regulation in predicting positive developmental outcomes. Participants were in Grades 7, 8, and 9 of the 4-H Study of PYD (N = 1311), a longitudinal study involving U.S. adolescents. A cross-lagged panel analysis using Structural Equation Modeling assessed the relations among hopeful future expectations and intentional self regulation across time in predicting PYD. Results indicated that earlier hopeful expectations for the future may be influential for later intentional self-regulation abilities, although both constructs were strong predictors of PYD in middle adolescence. We discuss implications for research and practice of hopeful expectations in adolescents' constructions of their positive futures.

An investigation of the theoretical content of physical activity brochures.

New evidence-based physical activity guidelines and recommendations for constructing messages supplementing the guidelines have been put forth. As well, recent reviewshave identified theoretical constructs that hold promise as targets for intervention: self-regulation, outcome expectancies and self-efficacy. The purpose of this study was to examine the integration of messages targeting self-regulation, self-efficacy and outcome expectancies in existing physical activity brochures. Twenty-two PA brochures from Canadian and American National Health Organizations were assessed for their use self-efficacy, self-regulatory processes and outcome expectancies. Brochures were analyzed line-by-line using a modified version of the validated Content Analysis Approach to Theory-Specified Persuasive Educational Communication (CAATSPEC; Abraham et al., 2007). One third of the brochures were coded by two independent raters coded a third of the brochures (n = 7). Inter-rater reliability was acceptable for 17 of the 20 categories (rs> .79). Discrepancies in all categories were discussed and agreement was reached. The remaining brochures were coded by one of the two raters. Usage of thethree key theoretical constructs accounted for only 36.43% of brochure content (20.23% self-efficacy, 10.40% outcome expectancies, 5.80% self-regulation). Brochures lacked the use of a variety of theoretical strategies, specifically goal-setting, planning and verbal persuasion and rarely highlighted the affective benefits of physical activity. In the future brochures should aim to place increased emphasis on self-regulation, self-efficacy, and affective outcome expectancies.

The identification of framed messages in the New York State Smokers' Quitline materials.

Research suggests that smoking cessation messages are most persuasive when framed in terms of the benefits achieved from quitting (i.e. gain-framed) than when framed in terms of the costs of not quitting (i.e. loss-framed). It is unknown, however, if these findings about optimal message frames have been translated into public health practice. The current study examined message framing in telephone counseling sessions with smokers calling the New York State Smokers' Quitline (NYSSQ). We conducted a content analysis of all NYSSQ print material and 12 Quitline service calls. Two independent raters coded each message within these documents as being gain-framed, loss-framed or non-framed. Messages from the service calls also were coded for their function (e.g. information provision, information gathering). Interrater reliability was acceptable (kappa > 0.80). Of the 997 print messages evaluated, 21.6% were gain-framed, 13.8% were loss-framed and 64.6% were non-framed. For the service calls, only the messages with an information provision function included framed content. Of the 420 information provision messages, 10.2% were gain-framed, 1.7% were loss-framed and 88.1% were non-framed. The loss-framed and non-framed messages indicate missed opportunities for providing gain-framed messages within the Quitline services, thus emphasizing a possible gap between research and practice.

Trajectories of positive and negative behaviors from early- to middle-adolescence.

Although the positive youth development (PYD) model initially assumed inverse links between indicators of PYD and of risk/problem behaviors, empirical work in adolescence has suggested that more complex associations exist between trajectories of the two domains of functioning. To clarify the PYD model, this study assessed intraindividual change in positive and problematic indicators across Grades 5-10, and the links between these trajectories of development, among 2,516 participants from the 4-H Study of PYD (58.1% females; 64.9% European American, 7.0% African American, 12.3% Latino/a American, 2.6% Asian American or Pacific Islander, 1.8% Native American, 3.0% multiethnic-racial, and 8.4% with inconsistent race/ethnicity across waves). Results from person-centered analyses indicated that most youth clustered in the high trajectories of positive indicators and in the low trajectories of the negative ones. Consistent with past research, overlap between trajectories of positive and negative behaviors was found. These results suggest that theory and application need to accommodate to variation in the links between positive and problematic developmental trajectories.

Positive pathways to adulthood: the role of hope in adolescents' constructions of their futures.

Hope has been studied within various disciplines since at least the 1950s, as researchers have attempted to describe, explain, and predict the association between human functioning and this seemingly vital-yet often abstract-construct. Recent work by Snyder and colleagues identified future goal orientation as a necessary component of hope. For developmental scientists, understanding the associations between hope and intentional self regulation strategies that may help young people achieve their goals could provide insight into the positive development of youth. In this chapter, we present a developmental systems framework for elucidating the links between hope and adaptive developmental outcomes, and we discuss recent research that provides evidence for the relationship between hopeful future expectations and thriving in the adolescent period. Finally, we provide guidelines for taking the next steps in not only assessing hope among diverse youth, but also in harnessing that hope for positive constructions of adolescents' pathways to adulthood.

Surfactant protein D regulates chemotaxis and degranulation of human eosinophils.

The collectin surfactant protein D (SP-D) is an important component of the pulmonary innate host defence. Up to now, little is known about the regulation of eosinophil function by SP-D. Various murine models of pulmonary hypersensitivity suggest that SP-D may be a potent anti-allergic protein. We investigated the modulation of eosinophil chemotaxis and degranulation by human SP-D. SP-D markedly inhibited the chemotaxis of eosinophils triggered by eotaxin, a major tissue-derived CC-chemokine, as shown in a modified Boyden chamber assay. In addition, degranulation of ECP in response to Ca2+ ionophore, immobilized IgG and serum from allergic patients was inhibited by SP-D. In a fixed-cell enzyme linked immunosorbent assay and in flow cytometry, SP-D bound to eosinophils. This binding was saturable and was inhibited by the addition of maltose and ethylenediaminetetraacetic acid, suggesting the involvement of the carbohydrate recognition domain of SP-D. In addition, flow cytometry showed significant interaction of SP-D with CD32 (FcgammaII receptor) on eosinophils, which might explain the inhibitory effect of SP-D on the IgG and serum-triggered eosinophil cationic protein degranulation of eosinophils. Our data further support the concept of an anti-inflammatory function of SP-D in the lung of patients with allergic diseases.
