以1551名初高中生为被试,采用问卷调查法探讨主观幸福感与网络成瘾的关系,以及自尊及自我控制在其中的中介效应。结果表明:(1)主观幸福感与自尊、自我控制能力之间显著正相关,且均与网络成瘾显著负相关;(2)青少年的主观幸福感水平显著负向影响其网络成瘾,而且还通过自尊和自我控制间接影响青少年的网络成瘾,并且间接效应更加明显;(3)在主观幸福感作用于网络成瘾的关系中,自尊及自我控制单独作用时的中介效应一般,但是当两者联合作用时中介效应大幅增加。     

Book reviews

Kashdan, Biswas-Diener, and King (2008) provide a wide-ranging critique of eudaimonic theory and research. In this paper, I question whether the timing of their analysis is appropriate given that work on eudaimonic constructs has begun only recently. In an effort to increase the clarity regarding points at issue, both conceptual and operational definitions of hedonia and eudaimonia as two conceptions of happiness are analyzed along with definitions of four conceptions of well-being (subjective, hedonic, psychological, and eudaimonic), and both hedonism and eudaimonism as ethical philosophies. Responses are provided to numerous points in the Kashdan et al. (2008 Kashdan, TB, Biswas-Diener, R and King, LA. 2008. Reconsidering happiness: The costs of distinguishing between hedonics and eudaimonia. Journal of Positive Psychology, 3: 219–233. [Taylor &; Francis Online] , [Google Scholar]) critique including their claims that work from a eudaimonic perspective (1) does not fully capture the philosophical roots of eudaimonia, (2) is overly abstract, (3) lacks clarity at the point of operationalization and measurement, (4) is overly complex thus preventing meaningful scientific inquiry, (5) provides evidence only for quantitative, not qualitative, differences, (6) is potentially elitist, and (7) misrepresents the moral standing of hedonia and eudaimonia. Evidence is presented in support of the view that hedonia and eudaimonia represent inter-related but reliably distinguishable and qualitatively distinct conceptions of happiness making independent contributions to an array of outcome variables. A set of recommendations is advanced as to how theory-building and empirical research can be strengthened in light of the multiple conceptualizations of happiness and well-being now current in the literature.     

Be careful what you wish for but also why you wish for it – Goal-striving reasons and subjective well-being

Individuals’ subjective well-being (SWB) when attaining their goals is moderated by the characteristics of their goals. Two significant moderators are whether goals are approach or avoidance oriented and their content. Within the goal-setting literature, these characteristics have been applied to goals as such, focussing on what it is people try to achieve. However, they can equally be applied to analyse why individuals pursue their goals. By applying the dimensions of approach and avoidance orientation as well as goal content to the analysis of goal-striving reasons, a framework has been developed encompassing the following four goal-striving reasons: goals pursuit because of pleasure, for altruistic reasons, out of necessity and for self-esteem reasons. The empirical findings (N?=?174) show that goal-striving reasons are significantly associated with affective SWB. Therefore goal-striving reasons provide an additional level of analysis, when analysing the relation between goals and affective SWB.     

By-Person Factor Analysis in Clinical Ethical Decision Making: Q Methodology in End-of-Life Care Decisions

Objective: To determine the usefulness of Q methodology to locate and describe shared subjective influences on clinical decision making among participant physicians using hypothetical cases containing common ethical issues.

Design: Qualitative study using by-person factor analysis of subjective Q sort data matrix.

Setting: University medical center.

Participants: Convenience sample of internal medicine attending physicians and house staff (n = 35) at one midwestern academic health sciences center.

Interventions: Presented with four hypothetical cases involving urgent decision making near the end of life, participants selected one of three specific clinical actions offered for each case. Immediately afterward and while considering their decision, each respondent sorted twenty-five subjective self-referent items in terms of the influence of each statement on their decision-making process. By-person factor analysis, where participants are defined as variates, yielded information about the attitudinal background the physicians brought to their consideration of each hypothetical case. We performed a second-order factor analysis on all of the subjective viewpoints to determine if a smaller core of shared attitudes existed across some or all of the four case vignettes. Factor scores for each item and post-sort comments from interviews conducted individually with each respondent guided the interpretation of ethical perspective used by these respondents in making clinical decisions about the cases.

Measurements and Main Results: Second-order factor analysis on seventeen viewpoints used by physicians in the four hypothetical urgent decision cases revealed three moderately correlated (r ² < 40%) subjective core attitudinal guides used broadly among all the cases and among sixteen of the seventeen original factors. Across all the cases, our participants were guided in general by: (1) patient-focused beneficence, (2) a patient- and surrogate-focused perspective that includes risk avoidance, and (3) best interest of the patient guided by ethical values. Economic impact on the physician, expediency in resolution of the situation, and the expense of medical treatment were not found to be influential determinants in this study.

Conclusions: Q sorting and by-person factor analysis are useful qualitative methodological tools to study the complex structure of subjective attitudes that influence physicians in making medical decisions. This study revealed the subjective viewpoints used by our physician participants as they made ethically challenging treatment decisions. The three second-order factors identified here are grounded in current bioethical values as well as the personal traits of physicians. The participants' decision methods appear to resemble casuistry more than principle-based decision making. Generalizability of results will require further studies.     

The evaluation of an equine-assisted therapy programme with a group of boys in a youth care facility

The goal of this study was to evaluate the efficacy of an equine-assisted therapy programme aimed at improving the psychological well-being of boys in a custodial school of industry. Participants were 39 boys who live in a youth care facility for boys who display problem behaviour. They were from different cultural groups (Black, Coloured, and White) and aged between 14 and 18 years. Horses were utilised in the structured sessions to help the boys learn different coping skills through experiential learning. Data were collected on the boys’ level of coping and subjective well-being in order to assess the efficacy of the programme. The data were analysed using independent groups t-test comparisons. The results showed that the programme significantly improved the boys’ subjective well-being, problem focused coping, and emotion focused coping. However, their levels of dysfunctional coping were unchanged following the intervention. An equine-assisted therapy programme appears to show modest evidence of enhancing psychological well-being of adolescent boys in custodial care.     

Two faces of human happiness: Explicit and implicit life satisfaction

Evidence is provided for implicit aspects of life satisfaction. In study 1 the implicit life satisfaction measure (ILS): (i) showed moderate reliability as well as convergent and incremental validity; (ii) appeared to be affected by temporary mood and social desirability to a lesser extent than explicit measures; and (iii) showed cultural invariance in contrast to explicit measures that revealed cross-cultural differences, as found in previous research. Study 2 showed that the ILS replicated theoretically expected differences between those known to have encountered chronically negative life experiences (North Korean defectors) and those without such experiences (South Koreans). Implications of these findings for explicit and ILS are discussed.     

Determinants of everyday time allocation

Two experiments examined the role of intentions in people's allocation of time to everyday activities (e.g., talcing a shower, running for exercise). In Experiment 1 32 subjects rated their intentions of, preferences for, and perceived control over performance of 10 activities at different frequencies during the following month. In Experiment 2 another 36 subjects performed the same ratings for the following week, then returned after that week to report how frequently they had been engaged in the activities. The results of both experiments showed that either the ratings of preference, of perceived control, or both combined linearly, predicted the intentions. However, intentions did not predict performance particularly well. This probably reflected (1) that some activities are performed routinely without intentions being formed; (2) that intentions to perform some other, more impulsively timed activities are formed late when appropriate actual situations are encountered; and (3) that for still other activities intentions are formed but not maintained.     

Life: Definition,Origin, and Evolution

Out of all the natural phenomena surrounding us, the phenomena Life, as a matter of course, is that which is the most mysterious and least understood of all. In many aspects, it seems as though it would be possible to investigate, study, and explain Life, like so many of the other subjects that fall within the category of the natural sciences: time, space, mass, movement, and so on. However, in its essence, Life is organized and managed differently than all other natural phenomena, operating, as it were, according to its own laws. Life certainly has certain clearly recognizable characteristics, such as: metabolism, homeostasis, continuity, and more. However, up until the present time, no definition for Life has been provided, which unifies it as an entity, and differentiates it unmistakably from other natural phenomenon. The current article offers a definition of the true nature of the phenomenon of Life, which in turn helps to explain the big questions of life—evolution, the mind–body problem, consciousness, and more.     

Revisiting the dimensional structure of the emotion domain

Recent research has claimed that a novelty dimension is needed to represent the cognitive emotion structure over and above valence, power and arousal. Novelty emerged when student samples evaluated the meaning of 24 emotion terms on 142 emotion features. This claim is debatable, however, because to date novelty has never been found in similarity sorting studies. It is possible that novelty emerged because sophisticated student samples evaluated emotion terms on emotion features. The current research identified a large, representative set of emotion terms using a free-listing task in a middle childhood up to early adulthood sample (N = 5071). Children, adolescents, students and adults (N = 1184) then evaluated the similarity between these emotion terms using a similarity rating task without priming any emotion feature. Novelty robustly emerged as the fourth dimension. The existence of novelty is thus confirmed with a different method across a wide variety of participants.     

Slowing Down the Clock: A Review of Experimental Studies Investigating Psychological Time Dilation

A review of 24 experiments investigated the factors that produce a subjective time dilation. The aim of this review was to investigate the magnitude of the obtained time dilation. The mean time duration judgment ratio of subjective time to objective time for the selected studies was 1.31, SD = .24. The analyses revealed that experimental studies investigating subjective time dilation tend to obtain small to moderate time dilation and that several factors can be manipulated in order to make a specific time interval appear longer than it is. Highlighting the factors that lead to a subjective time dilation has both research implications, by pointing to the underlying cognitive mechanisms of time perception, and practical implications, by indicating the factors that can be manipulated in order to control how we perceive time.
