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.     

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.     

Probing the history of social psychology,exploring diversity and views of the social: Publication trends in the European Journal of Social Psychology from 1971 to 2016

The European Journal of Social Psychology (EJSP), as the voice of the European Association of Social Psychology, aims to promote diversity and a distinctively ‘European’, more ‘social’, social psychology (SP). However, whether and how these objectives have been accomplished over time remains controversial. This article enters this debate, tracing the history of SP as depicted by EJSP publications, via two types of lexicometric analyses of all abstracts of the Journal (1971–2016). Themes, processes, methods, and their organisation in cycles and clusters over time, were identified and analysed. Regarding diversity, findings indicate that the publications reflect several of the new theoretical proposals that emerged over the years, but do not fully reflect the variety of perspectives and methods of the discipline. It further indicates that lately the ‘social’ is predominantly present in attention to pressing social issues, albeit the processes involved in them are mostly theorised at an individualistic level. This pattern suggests the importance of keeping open the quest for epistemological and methodological diversity, and of re-problematising what the ‘social’ in SP means. By contributing to mapping the history of SP, offering a more comprehensive and reflexive view for it, the present analyses also help in forging a stronger discipline.     

Investigating contingencies: an examination of the impact of span of supervision and upward controllingness on leader-member exchange using traditional and multivariate within- and between-entities analysis

Using a sample of 150 bank employees, span of supervision and subordinate use of influence tactics were examined as moderators of relationships between leader-member exchange (LMX) and subordinate performance and organizational commitment. Raw score analyses indicate that moderators are present. Span of supervision and upward controlling influence tactics moderate relationships between LMX and both performance and commitment. However, using multiple relationship analysis and multivariate within- and between-entities analysis to assess the level of analysis results in some discrepant findings. These discrepancies are discussed, as are implications for future LMX research.     

Self–Other Relations in Biodiversity Conservation in the Community: Representational Processes and Adjustment to New Actions

This research explores the simultaneous role of two Self–Other relations in the elaboration of representations at the micro‐ and ontogenetic levels, assuming that it can result in acceptance and/or resistance to new laws. Drawing on the Theory of Social Representations, it concretely looks at how individuals elaborate new representations relevant for biodiversity conservation in the context of their relations with their local community (an interactional Other) and with the legal/reified sphere (an institutional Other). This is explored in two studies in Portuguese Natura 2000 sites where a conservation project calls residents to protect an at‐risk species. Study 1 shows that (i) agreement with the institutional Other (the laws) and meta‐representations of the interactional Other (the community) as approving of conservation independently help explain (at the ontogenetic level) internalisation of conservation goals and willingness to act; (ii) the same meta‐representations operating at the micro‐genetic level attenuate the negative relation between ambivalence and willingness to act. Study 2 shows that a meta‐representation of the interactional Other as showing no clear position regarding conservation increases ambivalence. Findings demonstrate the necessarily social nature of representational processes and the importance of considering them at more than one level for understanding responses to new policy/legal proposals.

Ontogeny of meal patterning in rats and its recapitulation during recovery from lateral hypothalamic lesions.

The development of feeding patterns was investigated in weanling rats and in rats with lateral hypothalamic lesions. From 16 to 25 days of age, the weanlings demonstrated a preprandial intake pattern, i.e., a positive correlation between meal size and time since the preceding meal. This subsequently declined while the postprandial relationship (correlation with time until subsequent meal) began to emerge such that by 30-35 days of age a full adult pattern was observed. Rats recovering from lateral hypothalamic lesions, for a brief period, also demonstrated a preprandial intake pattern. The postprandial relationship was abolished by the lesions. These results suggest that the development of adult meal patterning results from maturation of lateral hypothalamic mechanisms governing meal initiation.     

An automated swim alley for small animals: I. Instrumentation

A swim alley for testing the long-term performance capacity of rats is described. Rats swim back and forth in an alley, in temperature-controlled water, between platforms that are alternately and automatically raised and lowered. At the end of each traverse, an animal is allowed to rest on a raised platform for a period of time before the platform is lowered, which initiates the next traverse. Continuous measurement is made of speed of movement between platforms.
