This study identified mediators of a school-based nutrition intervention for 4th graders and their parents. Nine variables were tested for satisfying 4 conclusions necessary to establish mediation of intervention effects on changes in fruit and vegetable consumption (FVC) in 4th graders (N = 1,676). FVC was measured in children by the use of 24-hr dietary recalls. Mediators were assessed by the use of questionnaires completed by children and parents. All 4 conclusions were met for positive outcome expectancies. Knowledge, self-efficacy, and parent consumption satisfied the first 3 conclusions for mediation but the mediating effects were not statistically significant (Conclusion 4). Future mediational analyses and the creation of a national database of mediators are crucial for increasing strength and efficiency of school-based nutrition programs. 相似文献

This study tested potential mediators of a school-based skin cancer prevention intervention for middle school children (6th-8th grades; N = 1,788). Ten variables were tested on 4 criteria to establish mediation, including (a) intervention related to outcome, (b) intervention related to mediators, (c) mediators related to outcome, and (d) mediated effect statistically significant. Sun-safe behaviors (e.g., sunscreen use) and potential mediators were measured with a self-report questionnaire. All criteria were met for Barriers--Sunscreen, Perceived Self-Efficacy, and Knowledge when the mediators were tested separately. In multiple mediator analyses, barriers to sunscreen use and self-efficacy satisfied Criteria 1-3 but were not statistically significant (Criterion 4). Barriers to sunscreen use, perceived self-efficacy for sun-safe behavior, and knowledge may serve as mediators. 相似文献

Parenting tends to be framed as a set of actions directed toward the child rather than as a relationship. This article helps therapists, parent-educators, and researchers conceptualize parenting as a socioculturally embedded relationship. The authors apply the relational orientations typology (Silverstein, Bass, Tuttle, Knudson-Martin, & Huenergardt, 2006) to parent-child relationships. The typology addresses two dimensions: whether the focus is on the child's meeting parental expectations or on expectations of mutuality and whether power between parent and child is expected to be symmetrical or asymmetrical. Four relational orientations are described: (1) rule directed, (2) position directed, (3) independence directed, and (4) relationship directed. These relational orientations describe the nature of the reciprocal relationship between parent and child and offer a framework from which to address parenting issues. A case illustration shows how the relational orientations framework helps therapists incorporate a larger systems/relational perspective into what was originally framed primarily as a child behavior problem. 相似文献

Previous studies have not fully investigated the psychometric properties of the Photographic Figure Rating Scale (PFRS). In 2 studies, we report on the test-retest reliability and convergent validity of ratings derived from the PFRS. In Study 1, 322 female university students in Britain provided self-ratings on the PFRS and objectively measured body mass index (BMI); a subsample of 132 women also completed the task after 5 weeks. In Study 2, 243 women from the community in Austria completed the PFRS along with a battery of other body image scales. Results of Study 1 showed that ratings on the PFRS had good test-retest reliability (all rs > .87) and good convergent validity in relation to BMI. Results of Study 2 showed that PFRS-derived body dissatisfaction scores were significantly correlated with a range of body image variables. These results provide evidence for the convergent validity and good test-retest reliability of the PFRS. 相似文献

We evaluated interrater agreement across multiple respondents on anecdotal assessments and compared cases in which agreement was obtained with outcomes of functional analyses. Experiment 1 evaluated agreement among multiple respondents on the function of problem behavior for 27 individuals across 42 target behaviors using the Motivation Assessment Scale (MAS) and the Questions about Behavioral Function (QABF). Results showed that at least 4 of 5 respondents agreed on the primary maintaining consequence for 52% (22 of 42) of target behaviors with the MAS and 57% (24 of 42) with the QABF. Experiment 2 examined correspondence between the anecdotal assessment results and functional analysis results for 7 individuals for whom at least 4 of 5 respondents showed agreement in Experiment 1. Correspondence with functional analysis results was observed in 6 of 7 cases with the QABF and in 4 of 7 cases with the MAS. Implications of these outcomes for the utility of anecdotal assessments are discussed. 相似文献

In a classic 1978 Memory &
Cognition article, Geoff Loftus explained why noncrossover interactions are removable. These removable interactions are tied to the
scale of measurement for the dependent variable and therefore do not allow unambiguous conclusions about latent psychological
processes. In the present article, we present concrete examples of how this insight helps prevent experimental psychologists
from drawing incorrect conclusions about the effects of forgetting and aging. In addition, we extend the Loftus classification
scheme for interactions to include those on the cusp between removable and nonremovable. Finally, we use various methods (i.e.,
a study of citation histories, a questionnaire for psychology students and faculty members, an analysis of statistical textbooks,
and a review of articles published in the 2008 issue of Psychology and
Aging) to show that experimental psychologists have remained generally unaware of the concept of removable interactions. We conclude
that there is more to interactions in a 2 × 2 design than meets the eye. 相似文献
