Quality of life after quitting smoking and initiating aerobic exercise

Quitting smoking and aerobic exercise each improve health. Although smokers may be concerned that quitting smoking will reduce their quality of life (QOL), recent research has shown that cessation is associated with QOL benefits. Elements of smoking cessation interventions, such as exercise, may contribute to changes in QOL. However, it is unknown whether initiating exercise in the context of smoking cessation is associated with greater or different effects on QOL than smoking cessation alone. The current study is a secondary analysis of data from a randomized trial (n = 61) of an exercise intervention for smoking cessation. We hypothesized that smoking abstinence and engagement in exercise would have positive, additive effects on QOL at end-of-treatment, 6- and, 12-month follow-ups. Sedentary adult smokers were randomized to the exercise intervention or a health education control (HEC) group. Additionally, all participants received smoking cessation counseling and nicotine patches. Data were analyzed using actual engagement in exercise, rather than group assignment as a proxy for exercise engagement, because some HEC participants also began exercising. Abstinence was positively associated with higher total and physical health QOL at follow-up. Exercise was not associated with total QOL and only marginally associated with physical health QOL, but was positively related to overall sense of well-being. Emphasizing that smoking cessation is associated with higher QOL may help motivate smokers to initiate quit attempts.     

Parent‐ and child‐driven effects during the transition to adolescence: a longitudinal,genetic analysis of the home environment

Theoretical models of child development typically consider the home environment as a product of bidirectional effects, with parent‐ and child‐driven processes operating interdependently. However, the developmental structure of these processes during the transition from childhood to adolescence has not been well studied. In this study we used longitudinal genetic analyses of data from 6646 UK‐representative twin pairs (aged 9–16 years) to investigate stability and change in parenting and household chaos in the context of parent–child bidirectional effects. Stability in the home environment was modest, arising mainly from parent‐driven processes and family‐wide influences. In contrast, change over time was more influenced by child‐driven processes, indicated by significant age‐specific genetic influences. Interpretations of these results and their implications for researchers are discussed.     

The free and cued selective reminding test for predicting progression to Alzheimer's disease in patients with mild cognitive impairment: A prospective longitudinal study

Amnestic mild cognitive impairment (aMCI) patients carry a greater risk of conversion to Alzheimer's disease (AD). Therefore, the International Working Group (IWG) on AD aims to consider some cases of aMCI as symptomatic prodromal AD. The core diagnostic marker of AD is a significant and progressive memory deficit, and the Free and Cued Selective Reminding Test (FCSRT) was recommended by the IWG to test memory in cases of possible prodromal AD. This study aims to investigate whether the performance on the FCSRT would enhance the ability to predict conversion to AD in an aMCI group. A longitudinal study was conducted on 88 aMCI patients, and neuropsychological tests were analysed on the relative risk of conversion to AD. During follow‐up (23.82 months), 33% of the aMCI population converted to AD. An impaired FCSRT TR was significantly associated with the risk of conversion to dementia, with a mean time to conversion of 25 months. The FCSRT demonstrates utility for detecting AD at its prodromal stage, thus supporting its use as a valid clinical marker.     

Validation of the University of California,Los Angeles Loneliness Scale (version 3) in Spanish older population: An application of exploratory structural equation modelling

Loneliness is a subjective and unpleasant experience associated to a variety of physical and mental health problems. Older people face an elevated risk of loneliness. It is measured through self-reported questionnaires, among which the most widely used one is the University of California, Los Angeles (UCLA) Loneliness Scale. The latest version of this scale is called UCLA-3, and it has not been validated in Spanish elderly population. This article aims to present a validation study of the Spanish version of the UCLA-3 for its use with older people, by establishing its reliability and validity. Data were obtained from the second wave of a longitudinal research conducted with older adults attending Lifelong Learning programs. The sample consisted of 335 people aged 55 years old or older. Sociodemographic data were collected, and loneliness was measured with the UCLA-3 and the de Jong Gierveld Loneliness Scale. Results have partially replicated a three factor structure already found in the literature in other populations. The present work provides relevant and innovative evidence, as this is the first time that the UCLA-3 was analysed using ESEM statistical approach in a Spanish elderly sample.     

The prevalence of cognitive disengagement in automobile crashes

The current study analysed crashes identified in a large-scale naturalistic driving database to assess the prevalence of cognitive disengagement (i.e., purely cognitive distraction and mind wandering/microsleep) or episodes wherein the driver did not look away from the roadway during secondary task completion or wherein another clearly observable contributing crash factor was not present, and the driver's reaction to the crash showed symptoms of cognitive disengagement. The study found that <1% (95% CI [0.45, 1.66]) of higher severity crashes had a potential contributing crash factor of mind wandering/microsleep; ~1.5% (95% CI [0.83, 2.32]) had a potential contributing factor of purely cognitive distraction. The results suggest a relatively low prevalence of cognitive disengagement among automotive crashes compared with visual/manual secondary tasks. However, the current methodology is limited in that it does not account for instances where cognitive disengagement, in combination with other factors, may have led to crashes, potentially leading to conservative estimates.     

Social dominance and individual aggressiveness

Male rats exhibiting high, moderate, or low levels of offensive aggressive behavior in interactions with intruders in their home cage were grouped in mixed-sex colonies with 1 male of each aggression-level group in each colony. Agonistic interactions measured 1, 2, 3, 7, 14, 21, and 22 days after colony formation indicated that highly aggressive males on pretests continued to be more aggressive, becoming the dominant colony male in five of seven colonies and attacking intruders more often than less aggressive males. In the two remaining colonies the moderately aggressive male became dominant. This relationship, which was consistent over a number of indices, including offensive and defensive behaviors, and wound counts and wound sites, was seen even when a substantial weight differential favored the less aggressive animal. Dominance relationships were rapidly established and within-group fighting declined significantly over the 21-day test period. Pretest offensive levels also influenced the behavior of subordinates, with high or moderately aggressive subordinates showing more defense in interactions with dominants and receiving more wounds than did low-aggression subordinates. Dominant males also showed more defense in interacting with those subordinates which had been more aggressive during pretests. This pattern of results suggests that aggression level of the subordinate as well as the dominant may be an important factor determining the intensity of agonistic interactions in male rats.     

Factorial confirmatory models of Ryff's scales in a sample of elderly people

Several recent works have analysed the factorial structure of well-being measures. The aim of our study is to analyse the factorial structure of a widely used well-being scale, Ryff's Scales of Psychological Well-being, but in a specific subpopulation of the Spanish population, the elderly. For this particular subpopulation, the construct of well-being has been employed in most theoretical models that explain quality of life, and its role is therefore pivotal. The sample comprised 169 elderly people (65 years or more), sampled within the Valencian Community. The 54-item version of Ryff's scales was used. An item parcelling process was analytically employed before confirmatory factor analyses, allowing a total of 18 well-being indicators. Confirmatory factor analyses were specified and tested, including all theoretical and empirical solutions found in the literature, either in the general population or in specific populations of different cultural contexts. Goodness-of-fit results were similar to the ones found in the literature. Best solutions were a six-factor model with correlated factors, as defended by the authors, and a five-factor correlated solution, collapsing environmental mastery and self-acceptance into a single factor.     

Offline and online automatic number comparison

This paper focuses on automatic number processing as instantiated in the size congruity effect. It was recently argued that long-term "associations between individual digits and the attributes 'small' and 'large' create the size congruity effect" (Choplin and Logan 2003, abstract, p. 17). Moreover, these authors proposed the additional assumption that the relevant connections are acquired over a lifetime of experience with numbers. We show that at least one of these assumptions is not true: either the size congruity effect derives from an (online) comparison effect between two numbers at the time of stimulus presentation (violating the first assumption) or the relevant connections flexibly change (offline) between trials during the course of one experimental session (violating the second assumption).     

Interpersonal politics: the role of terror management and attachment processes in shaping political preferences

Research on terror management theory (TMT) indicates that reminders of death affect political attitudes, but political orientation only sometimes moderates these effects. We propose that secure relationships are associated with values of tolerance and compassion, thus orienting people toward liberalism; insecure attachments are associated with more rigid and absolutist values that orient people toward conservatism. Given that attachment relationships become especially active when security needs are heightened, we predicted that mortality salience would be an important factor in understanding the relationship between attachment processes and political orientation. Supporting these ideas, Study 1 showed that after a mortality-salience manipulation, securely attached participants increased their support for a liberal presidential candidate, and less securely attached participants increased their support for a conservative presidential candidate. In Study 2, a secure-relationship prime following a mortality-salience manipulation engendered a less violent approach to the problem of terrorism than did a neutral-relationship prime. We discuss the interaction of TMT processes and individual differences in attachment in shaping political preferences.     

Is attention necessary for object identification? Evidence from eye movements during the inspection of real-world scenes

Eye movements were recorded during the display of two images of a real-world scene that were inspected to determine whether they were the same or not (a comparative visual search task). In the displays where the pictures were different, one object had been changed, and this object was sometimes taken from another scene and was incongruent with the gist. The experiment established that incongruous objects attract eye fixations earlier than the congruous counterparts, but that this effect is not apparent until the picture has been displayed for several seconds. By controlling the visual saliency of the objects the experiment eliminates the possibility that the incongruency effect is dependent upon the conspicuity of the changed objects. A model of scene perception is suggested whereby attention is unnecessary for the partial recognition of an object that delivers sufficient information about its visual characteristics for the viewer to know that the object is improbable in that particular scene, and in which full identification requires foveal inspection.
