Telephone versus mail interventions for maintenance of physical activity in older adults.

Although telephone and mail are often used to promote physical activity adoption, their ability to produce long-term maintenance is unclear. In this study, 140 men and women aged 50-65 years received 1 year of telephone counseling to adopt higher (i.e., more vigorous) versus lower intensity (i.e., moderate) exercise. After 1 year, participants were rerandomized to a 2nd year of contact via (a) telephone and mail or (b) predominantly mail. Participants who were prescribed higher intensity exercise and received predominantly mail had better exercise adherence during the maintenance year than those who received telephone and mail. Both strategies were similarly effective in promoting maintenance in the lower intensity condition. Results suggest that after successful adoption of physical activity with the help of telephone counseling, less intensive interventions are successful for physical activity maintenance in older adults.     

Spanish adaptation of the NDSS (Nicotine Dependence Syndrome Scale) and assessment of nicotine-dependent individuals at primary care health centers in Spain

The availability of adequate instruments for the assessment of nicotine dependence is an important factor that is relevant in the area of tobacco addiction. In this study, we present a Spanish validation of the Nicotine Dependence Syndrome Scale (NDSS) (Shiffman, Waters, & Hickcox, 2004). The sample was composed ofpatients, all daily smokers, who visited their General Practitioner (GP) at five Primary Health Care Centers in different cities of Spain (N = 637). The results indicated adequate reliability for the general factor that assesses nicotine dependence (NDSS-Total) (Cronbach's alpha = .76). Factor analysis confirms the five factors of the original validation: Drive, Continuity, Stereotypy, Priority, and Tolerance. It must be noted that reliability is adequate for the first, and moderate or low for the rest. The NDSS-T and its scales correlate significantly with the Fagerstr?m Test for Nicotine Dependence (FTND), with the nicotine dependence criteria of the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) as assessed through the Structured Clinical Interview for DSM-IV (SCID), with carbon monoxide levels in expired air (CO), and with the number of cigarettes smoked. The ROC curve indicates that the NDSS-T has a score of .79 which is under the curve (.69 for the FTND), thus the prediction of nicotine dependence is adequate. We conclude that this instrument is useful (in terms of its total score NDSS-T) for assessing nicotine dependence for Spanish smokers (in Spain), as has been found in other countries, language groups, and cultures.     

Parents' Emotion‐Related Beliefs,Behaviours, and Skills Predict Children's Recognition of Emotion

Children who are able to recognize others' emotions are successful in a variety of socioemotional domains, yet we know little about how school‐aged children's abilities develop, particularly in the family context. We hypothesized that children develop emotion recognition skill as a function of parents' own emotion‐related beliefs, behaviours, and skills. We examined parents' beliefs about the value of emotion and guidance of children's emotion, parents' emotion labelling and teaching behaviours, and parents' skill in recognizing children's emotions in relation to their school‐aged children's emotion recognition skills. Sixty‐nine parent–child dyads completed questionnaires, participated in dyadic laboratory tasks, and identified their own emotions and emotions felt by the other participant from videotaped segments. Regression analyses indicate that parents' beliefs, behaviours, and skills together account for 37% of the variance in child emotion recognition ability, even after controlling for parent and child expressive clarity. The findings suggest the importance of the family milieu in the development of children's emotion recognition skill in middle childhood and add to accumulating evidence suggesting important age‐related shifts in the relation between parental emotion socialization and child emotional development.

Ecumenism and Evangelicalism: Where Are We?

While the ecumenical movement, and particularly the World Council of Churches, must always be an inclusive forum where the richness of the total life of the Christian church is manifest, this article argues that evangelicals cannot give up the quest for church unity because that would mean ignoring a central aspect of the prayer of Jesus Christ. Looking at areas of convergence between the evangelical and the ecumenical movement, four areas are identified for further cooperation and dialogue: the authority of the Bible; mobilizing all churches for the evangelization of the whole world; the perspective of the poor; and the challenge of justice and peace.     

PISA and the assessment triangle

PISA is a well-known and high profile Program for International Student Assessment with 4 editions since 2000. This study aims to examine the validity of PISA proficiency estimates, working with the framework provided by the assessment triangle. We pay explicit attention to how PISA proceeds as far as the three elements of the assessment triangle are concerned: cognition, observation, and interpretation. Results reveal not only the psychometrically sound proficiency estimates of PISA and the high standards reached, but also that there is room for improvement; for instance, cognitive diagnostic models could contribute both to test design and data analysis.     

The Short Nicotine Dependence Syndrome Scale (NDSS-S) in Spanish smokers

We present a brief scale derived from the Nicotine Dependence Syndrome Scale (NDSS). We used a sample of 1.061 daily smokers, which was obtained from five Primary Care Health Centers, a Unit of Alcoholism, and a Smoking Cessation Unit. All smokers were evaluated with the NDSS and the SCID to assess nicotine dependence according to DSM-IV criteria. The results indicate the existence of a general factor of nicotine dependence according to the NDSS. We selected the items with a higher factor loading (>.50), obtaining a short scale of 6 items. With this brief scale, we obtained results similar to those of the total scale in the diverse variables (sociodemographic and smoking) of the study. Scale reliability is satisfactory (a= .79), the correlation between the short and the total scale is very high (r=.95, p<.001) and the short scale discriminates the smokers in terms of cigarette consumption and nicotine dependence, as assessed with the SCID. The operation under the ROC curve is excellent (area under the curve .84). The data indicate the usefulness of this brief scale (NDSS-S) to assess nicotine dependence in smokers.     

Typical development of quantity comparison in school-aged children

Although basic numerical skills have been widely studied in the last years, very few studies have undertaken a developmental approach. The present study evaluated the development of the magnitude comparison basic numerical ability, in children from first, third and sixth grades by means of the subject's response time in numerical tasks presented in symbolic and non-symbolic formats. The results showed a significant decrease on quantities processing speed as age increases, which suggests numerical skills tend to become automatic with instruction. The differences found, concerning the general achievement pattern in each school year, might express the maturational specificities of the numerical representation system through development.     

Event-related EEG oscillations to semantically unrelated words in normal and learning disabled children

Learning disabilities (LD) are one of the most frequent problems for elementary school-aged children. In this paper, event-related EEG oscillations to semantically related and unrelated pairs of words were studied in a group of 18 children with LD not otherwise specified (LD-NOS) and in 16 children with normal academic achievement. We propose that EEG oscillations may be different in LD NOS children versus normal control children that may explain some of the deficits observed in the LD-NOS group. The EEGs were recorded using the 10/20 system. EEG segments were edited by visual inspection 1000ms before and after the stimulus, and only correct responses were considered in the analysis. Time-frequency (1-50Hz) topographic maps were obtained for the increases and decreases of power after the event with respect to the pre-stimulus average values. Significant differences between groups were observed in the behavioral responses. LD-NOS children show less number of correct responses and more omissions and false alarms than the control group. The event-induced EEG responses showed significant differences between groups. The control group showed greater power increases in the frequencies 1-6Hz than the LD-NOS group from 300 to 700ms. These differences were mainly observed in frontal regions, both to related and non-related words. This was interpreted as a deficit in attention, both to internal and external events, deficits in activation of working memory and deficits in encoding and memory retrieval in the LD-NOS children. Differences between groups were also observed in the suppression of alpha and beta rhythms in the occipital regions to related words in frequencies between 8 and 17Hz from 450 to 750ms. LD-NOS children showed shorter durations of the decreases in power than the control group. These results suggest also deficits in attention and memory retrieval. It may be concluded that LD-NOS children showed physiological differences from normal children that may explain their cognitive deficiencies.
