A measure of smoking outcome expectancies was developed for children ages 7-12 years. Confirmatory factor analysis (CFA) was used to determine whether a 1-, 2-, 3-, or 4-factor solution was most appropriate for the data set. CFA revealed that the 3-factor model produced the most adequate fit (Positive Reinforcement, Negative Consequences, and Weight Control). The resulting 15-item measure was named the Smoking Consequences Questionnaire-Child (SCQ-C). The fit of the 3-dimensional structure was then examined separately for 3 age groups representing young (7- to 8-year-old), middle (9- to 10-year-old), and old (11- to 13-year-old) children. Overall, the 3-factor structure fit the data well for the 3 groups. As such, we examined the relations of the 3 scales with antecedent variables for the entire sample. The Positive Reinforcement scale was associated with children's smoking behavior and having a family member or peers who smoked. The Negative Consequences scale was inversely related to having a family member or peer who smoked.  相似文献

We offered introductory psychology on the World-Wide Web (WWW) and evaluated the on-line format relative to the traditional lecture-test format, using a pretest-posttest nonequivalent control group design. Multiple sections of the introductory course were offered each semester; on-line and lecture sections were taught by the same instructor, the same textbook was used, and the same in-class examinations were taken. For on-line sections, mastery quizzes, interactive individual exercises, and weekly laboratory meetings replaced lectures. Increased content knowledge was greater for the students in the Web sections, as was in-class examination performance. Use of the WWW and computers for academic purposes increased more in the on-line sections, and the on-line students showed a greater decrease in computer anxiety. The students in the on-line sections expressed appreciation for course components and the convenience of the course, but the lecture sections received higher ratings on course evaluations than did the on-line sections. Learning and course satisfaction were dissociated in the two course formats.  相似文献

Club good models developed by economists suggest that the club provides a benefit to members by fostering the provision of semi-public goods. In the case of religion, churches create enforcement mechanisms to reduce free riding. Consequently, the psychic costs of deviant activity should be higher for individuals who belong to religious groups with strong social norms. Data from the General Social Survey are used to examine whether the cost of using pornography is greater for the more religiously involved. We measure the cost of using pornography as the happiness gap or the gap between the average happiness reported by individuals who do and individuals who do not report using pornography. The happiness gap is larger for individuals who regularly attend church and who belong to religious groups with strong attitudes against pornography.  相似文献

Numerous studies have established that visual working memory has a limited capacity that increases during childhood. However, debate continues over the source of capacity limits and its developmental increase. Simmering (2008) adapted a computational model of spatial cognitive development, the Dynamic Field Theory, to explain not only the source of capacity limitations but also the developmental mechanism. Capacity is limited by the balance between excitation and inhibition that maintains multiple neural representations simultaneously in the model. Development occurs according to the Spatial Precision Hypothesis, which proposes that excitatory and inhibitory connections strengthen throughout early childhood. These changes in connectivity result in increasing precision and stability of neural representations over development. Here we test this developmental mechanism by probing children's memory in a single-item change detection task. Results confirmed the model's predictions, providing further support for this account of visual working memory capacity development.  相似文献

As family therapists increasingly practice in healthcare settings, they need to be aware of forthcoming changes in healthcare policy and the impact of these changes on their clinical work and the lives of their clients. In this paper, we provide a primer on healthcare policy for family therapists, which describes current and proposed changes in healthcare that will potentially revolutionize healthcare delivery for families. We describe three key initiatives: (1) Triple Aim; (2) the Accountable Care Organization; and (3) the Patient Centered Medical Home. We conclude with a discussion about future directions and healthcare policies that include families.  相似文献
