Adolescents’ movement towards cessation of smoking: Role and relative value of the processes of change and nicotine dependence

The present study addresses the applicability of the Transtheoretical Model's processes of change in explaining adolescents’ readiness to quit smoking. Furthermore, the association between nicotine dependence and readiness to quit was assessed both directly, as well as indirectly through the processes of change. A cross-sectional survey was conducted, identifying 1547 weekly smokers aged 14–18 years. Structural equation modelling showed that the processes of change were only marginally associated with readiness to quit. Adding nicotine dependence to the model showed a direct association between nicotine dependence and readiness to quit. Only one process of change, self-liberation (i.e. choice/commitment to change and belief in the ability to change), was found to mediate this association. Nicotine dependence appeared to be highly important in adolescents’ readiness to quit.     

Distorted Reflections: Media Exposure and Latino Adolescents' Conceptions of Self

Because Latinos are underrepresented and often negatively stereotyped in the media, concern is frequently expressed that repeated exposure to these portrayals may reflect poorly on Latino adolescents' self-esteem. To test this issue empirically, we conducted 2 studies examining associations between multiple dimensions of self-esteem and several forms of media use. Testing 40 Latino high school students in Study 1, we found that more frequent and more active TV viewing was associated with lower social and appearance self-esteem. Many of these general patterns were replicated in Study 2 with 115 college students and with several demographic controls. Additional analyses of possible moderators revealed more consistent negative correlations among women and among participants with a stronger Latino ethnic identity. Together, these findings provide powerful evidence of a potential link between media use and the self-conceptions of Latino youth.     

Parents' structuring of children's daily lives in relation to the quality and stability of children's friendships

This study focused on the implications of parents' structuring of their children's home lives for the friendships of their children. Participants were 224 elementary‐school children (108 girls and 116 boys) from four grade levels in two schools in Aix‐en‐Provence, France. Most of the families were of middle or high socio‐economic status. The participating children were seen twice during the same school year in order to assess the stability of their friendship choices and the quality of their friendships. We used Lautrey's (1989) questionnaire in order to assess the parents' styles in the structuring of family life and related child‐rearing practice. This questionnaire delineates three structuring styles: 1) rigid, characterized by considerable imposition of routines with little leeway for exceptional circumstances; 2) flexible, in which established routines can be modified as circumstances dictate; and 3) laissez‐faire, characterized by an absence of predictability and routine. We measured friendship quality by means of Friendship Quality Scale developed by Bukowski, Hoza, and Boivin (1989). This scale consists of 23 items representing five dimensions: companionship, help, security, closeness and conflict. This tool was designed to elicit children's perceptions of a specific relationship with a friend. Results indicated a significant link between parenting style and both of the dimensions of child friendship we studied. Children from homes characterized by a laissez‐faire style of parenting have friendships with more positive features than children from homes with flexible or rigid styles. We also found that friendships were generally less stable and rated as less positive than in similar studies conducted in other countries.     

Imagining and Explaining Hypothetical Scenarios: Mediational Effects on the Subjective Likelihood of Health‐Related Outcomes1

Imagining and explaining hypothetical events have been shown to increase the subjective likelihood of those events occurring. At the same time, it has been suggested that reducing unrealistic optimism about health risks (i.e., increasing the subjective likelihood of negative health outcomes) might motivate health‐protective behavior. In exploring the implications of these issues for health‐promotion goals, 2 experiments (Ns= 334 and 328) involving postal questionnaires are reported in which attempts are made through the use of imagine‐and‐explain scenarios to manipulate the subjective likelihood of a negative outcome (heart disease) and of a positive outcome (reducing fat consumption). The greater success of the manipulation of dietary change expectations than of heart disease expectations suggests the potential benefits of focusing directly on planning goal strategies in relation to health beneficial behaviors.     

Intelligence, Callous-Unemotional Traits, and Antisocial Behavior

Research has consistently shown that children with severe conduct problems often exhibit intellectual deficits, especially in their verbal abilities. We investigated whether or not this finding only applies to certain subgroups of children with severe conduct problems. In a sample of 117 clinic-referred children between the ages of 6 and 13, we assessed for Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD) symptoms using a structured diagnostic interview with each child's parent and teacher, callous and unemotional traits using parent and teacher ratings, and intellectual functioning using a standard individually administered intelligence test. Children with an ODD or CD diagnosis who did not show callous and unemotional traits showed a deficit on subtests measuring verbal reasoning ability relative to a clinic control group. Children with an ODD or CD diagnosis who also showed callous and unemotional traits did not show a verbal deficit and, in fact, showed a trend toward having weaker nonverbal abilities. These results highlight the importance of recognizing distinct subgroups of children with severe conduct problems when studying potential intellectual deficits in these children.     

APPRENTISSAGE DE LA CONSERVATION DES QUANTITÉS LIQUIDES CHEZ DES ENFANTS RWANDAIS ET CANADIENS-FRANCAIS1

Three groups of 16 subjects (rural school Rwandese, rural unschooled Rwandese and urban school French-Canadian children), classified as preoperational on a pretest including eight tests of conservation, were trained on the conservation of liquid quantities by a method based on anticipation of levels and compensation of dimensions. It was found that a) the performance of all three groups, when compared with controls, was significantly higher on two successive post-tests (two months interval); b) the three groups did not differ from one another either in global scores on both post-tests or in number of training sessions required for learning; c) the types of justification were based predominantly on perceptual features and on identity in non-conservation and conservation judgments, respectively. Results are discussed mainly in terms of the kind of justifications given by the three groups, the relative effectiveness of the two types of training given, and the genuineness of the conservation induced.     

Mindfulness-based stress reduction among Emirati Muslim women

Explorations of mindfulness-based psychotherapeutic approaches are relatively scarce outside of Europe and North America. This study examined the effectiveness and the religio-cultural appropriateness/acceptability of a Mindfulness-based Stress Reduction (MBSR) programme among Muslim citizens of the United Arab Emirates. Emirati college women (N?=?12) were enrolled in an eight-week, group-based, MBSR programme. After completing the programme, participants attended a focus group exploring their perceptions of MBSR, with a particular emphasis on exploring the cultural appropriateness of this approach. The MBSR programme was favourably evaluated, and not in any way deemed antithetical towards the participants' own theistic or cultural traditions. The results are discussed with reference to identifying bridging concepts to help better contextualise MBSR for people who spontaneously couch their experiences in religious themes, or who explicitly express a desire for faith-affiliated interventions.     

Dual Processing of Open- and Closed-Class Words

A series of articles in the past two decades has suggested differential processing of open- and closed-class lexical items by normal adults. Difficulties in replicating a crucial study (Bradley, 1978), however, have weakened the dual route hypothesis. We matched 16 French open-class items to 16 closed-class items for phonological structure, word length, and relative word frequency. Three agrammatic aphasics were asked to read each word in isolation and in a sentence context. Error analysis revealed strikingly more phonological errors on closed-class than open-class items. Dysfluencies were greater on closed-class items and contributed to greater overall reading time for the closed-class words, consistent with a two-route model for the production of closed- and open-class lexical items in Broca's aphasics and, thus, normals.
