Life satisfaction and satisfaction in domains of life: is it a simple relationship?

This paper studies the nature of the relationship between life satisfaction and satisfaction in domains of life. The domains-of-life literature assumes that a person’s overall satisfaction with his or her life depends on his or her satisfaction in many concrete areas of life, which are classified into a few main domains of life. This paper addresses the issue of what characteristics the relationship between life satisfaction and satisfaction in domains of life has by focusing on its specification. The domains-of-life literature has commonly assumed that an additive relationship between domains satisfaction and life satisfaction does exist. This paper argues that the use of an additive relationship has substantially restricted our comprehension of the relationship; since it makes impossible to empirically address questions such as: Is life satisfaction just a weighted average of domain satisfactions? How easy is it to substitute satisfaction in one domain by satisfaction in another? Is it reasonable to expect similar additional benefits when we continuously improve satisfaction in one domain? What happens with our life satisfaction when we manage to continuously improve satisfaction in all domains? What happens with the importance of one domain when satisfaction in another domain declines? The paper argues that there could be substantial gains in the understanding of the relationship by assuming alternative specifications. At an empirical level the investigation works with four different specifications: an additive relationship, a semi-logarithm relationship, a logarithm–logarithm relationship, and a constant elasticity of substitution (CES) relationship. Using a database from Mexico, the investigation finds out that an additive specification provides – at least for Mexico – a goodness of fit similar to those of alternative specifications. However, there are some relevant issues in the relationship between domains satisfaction and overall life satisfaction that cannot be studied with an additive specification; hence, the?use of an alternative specification – in particular a CES specification – is preferable if the objective is to understand rather than to predict life satisfaction.     

Searching for Spiritual Signatures in SETI Research

The Search for Extraterrestrial Intelligence (SETI) research assumes that we live in an intelligence-friendly universe. But do we live in a spiritual-friendly universe? We include the spiritual quest in a new multidisciplinary approach to SETI. In a thought experiment, we consider two types of alien civilizations by including a Spiritual factor in the Drake Equation. Using the analogy of planetary biomarkers and the concept of noosphere introduced by Teilhard de Chardin, we propose two spiritual markers that could evidence the presence of a noosphere in an exoplanet.     

Generalization of the Brown-Forsythe approach to factorial designs

The current paper proposes a solution that generalizes ideas of Brown and Forsythe to the problem of comparing hypotheses in two-way classification designs with heteroscedastic error structure. Unlike the standard analysis of variance, the proposed approach does not require the homogeneity assumption. A comprehensive simulation study, in which sample size of the cells, relationship between the cell sizes and unequal variance, degree of variance heterogeneity, and population distribution shape were systematically manipulated, shows that the proposed approximation was generally robust when normality and heterogeneity were jointly violated.     

Influence of autonomy support, social goals and relatedness on amotivation in physical education classes

The purpose of this study was to analyze some factors that influence amotivation in physical education classes. A sample of 399 students, of ages 14 to 16 years, was used. They completed the Perceived Autonomy Support Scale in Exercise Settings (PASSES), the Social Goal Scale-Physical Education (SGS-PE), the factor of the Basic Psychological Needs in Exercise Scale (BPNES) adapted to physical education and the factor of the Perceived Locus of Causality Scale (PLOC). The psychometric properties of the PASSES were analyzed, as this scale had not been validated to the Spanish context. In this analysis, the scale showed appropriate validity and reliability. The results of the structural equation model indicated that social responsibility and social relationship goals positively predicted perception of relatedness, whereas the context of autonomy support did not significantly predict it. In turn, perception of relatedness negatively predicted amotivation. The findings are discussed with regard to enhancing students' positive motivation.     

Social Influence in Personally Relevant Contexts: The Respect Attributed to the Source as a Factor Increasing Smokers’ Intention to Quit Smoking1

The study examined the effects of the status of the source in personally relevant persuasion contexts. Smokers (N= 117) with either weak or strong identity as smokers were exposed to an anti‐smoking message, targeting either the tobacco industry or smokers, and attributed either to a health institute or a neighborhood association. The main dependent variable was the change in intention to quit smoking. As expected, the neighborhood association was considered more respectful of the freedom of choice of the target than was the health institute. In high personal relevance conditions (i.e., participants with strong identities as smokers and message explicitly targeting smokers), smokers strengthened their intention to quit smoking when the source was the neighborhood association, but decreased it when the source was the health institute. Implications for health campaign implementation are discussed.     

Utility of composite and multiple criteria measuring discriminative efficiency in personnel selection

The present study examined the utility of decision making in personnel selection comparing multiple and composite criteria by discriminative efficiency, in a bricklaying training program. We have found valid predictors (aptitudes, personality and experience) with different forms of the criterion, the ERPF scale, in logistic and multiple regression analysis. Results seem indicate that there is not a better criterion, so it depends on different conditions and different aims to reach. We proposed criteria as combining measures but not opposed.     

Old and new controversies in the alternative treatment of attention-deficit hyperactivity disorder

Use of complementary and alternative medicine (CAM) for treatment of attention-deficit hyperactivity disorder (ADHD) has become widespread in both referral and primary care populations. We review the purported mechanism of action and available evidence for selected CAM therapies for ADHD. Enduring controversies, such as elimination of artificial food additives, colors, and/or preservatives; the effect of sugar on behavior in children; and the use of EEG biofeedback, have been well studied but lack support as effective sole treatments for ADHD. The initial evidence for some emerging CAM therapies, such as essential fatty acid supplementation, yoga, massage, homeopathy, and green outdoor spaces, suggests potential benefits as part of an overall ADHD treatment plan. More rigorously designed studies are needed to evaluate their effectiveness as single therapy for ADHD.     

Why do we share aggressive online content? Testing a short cycle model

The present study aimed to observe the impacts of aggressive online content exposure and personality on aggressive content sharing, considering the mediating role of positive and negative affects. A total of 302 Brazilians, equally divided into two groups, participated in a social network simulation, being exposed to aggressive (experimental group) or neutral (control group) posts and choosing what they would like to share on this site (among aggressive or nonaggressive material). A factorial MANOVA showed a significant difference for positive and negative affects and aggressive content sharing (Wilks' Λ = 0.936; F[3, 298] = 6.812; p = .001; η² = 0.064). Through structural equation modeling, an explanatory model was also tested, in which this behavior was directly predicted by aggressive online content exposure and suffered indirect effects from openness, conscientiousness, and extroversion, mediated by positive affects (goodness-of-fit index = 0.997, comparative fit-index = 0.998, Tucker-Lewis index = 0.996, SRMR = 0.028, root-mean-square error of approximation = 0.035, CI = 0.003−0.054). It is possible to conclude that the objectives are met, highlighting the contribution to understanding aggressive online behavior through the proximal processes described in the general aggression model.     

Alcohol and Drug Use, and Depression Among Hispanic Men in Early Adulthood

Community research and clinical practice have shown that alcohol and drug use and depression are interrelated. Among Hispanics, acculturation may play a role in these relationships. To investigate these relationships as well as alcohol-related problems, we interviewed 288 Puerto Rican, Dominican, and Colombian men in early adulthood. No significant differences emerged in the proportions of abstainers across the three groups. Colombians drank significantly more frequently and had more alcohol-related problems than Dominicans. Dominicans were at least risk for and least likely to have alcohol-related problems. Puerto Ricans were much more likely to use drugs than the other Hispanic men. Drug use was associated with an increased likelihood of heavy drinking which, in turn, increased the risk of drug use and depression. Acculturation decreased the risk of drug use. Results are discussed in terms of implications for community psychology research and interventions.
