Breast cancer is a devastating disease that affects thousands of women every year influencing their psychological and physical well-being for many years after being diagnosed. The goal of the current study was to determine if there are distinct trajectories of functioning among breast cancer patients in the domains of negative psychological adjustment, positive psychological adjustment, and physical adjustment. This was accomplished using growth mixture modeling. Another goal of this study was to determine whether demographic, medical, and psychosocial variables were able to distinguish among the trajectories. The study combined women from two samples spanning 10 years providing a sample size of 376 women diagnosed and treated for breast cancer. These women were recruited to participate in a 10-week cognitive behavioral stress management intervention and were either randomized to the 10-week experimental condition or a one-day control group. It was hypothesized that distinct trajectories would emerge for each of the domains and that psychosocial variables (i.e., social support, benefit finding, and emotional approach coping) would distinguish among the trajectories. This study was able to statistically identify multiple classes or trajectories of adjustment, consistent with findings reported by Helgeson and colleagues (2004) and Donovan and colleagues (2007). It is difficult to say, however, whether these classes differ in clinically significant ways. The present study also provides a cautionary note to researchers who intend to use growth mixture modeling to identify different trajectories of functioning and the limitations associated with this statistical technique. First, it is important to start this process with strong empirical or theoretical support for the possibility of different classes or trajectories. Without this foundation it becomes difficult to justify why a certain number of classes were chosen. Another limitation of this statistical approach is that there is not a standard method for determining the best number of classes. There are conflicting opinions among researchers in the field about the best fit index to use when the multiple fit indices do not converge. A serious issue related to this is the fact that classes are used for interpreting results and drawing conclusions and inferences. Therefore, clinicians using GMM must be careful when deciding on the number of classes and the clinical inferences drawn from these analyses. Further research needs to be conducted validating these statistical techniques.

The aim of this study was to evaluate the potential contribution of religious involvement, spiritual well-being, existential well-being and HIV-related symptoms to health-related quality of life in HIV-infected African American women recovering from substance abuse. The study also examined whether religious and spiritual variables served as potential moderators between HIV symptoms and health-related quality of life. This study relied on data obtained as part of a larger longitudinal investigation of the effectiveness of Structural Ecosystems Therapy (SET) for HIV infected women in substance abuse recovery. A total of 175 participants were recruited from regional residential and outpatient clinics. The sample in this study included 99 African American women who had completed the required baseline assessment. It was hypothesized that religious involvement, spiritual well-being and existential well-being would be positively associated to various health-related quality of life indicators (i.e., physical functioning, social functioning, mental health functioning and health distress). On the other hand, HIV symptoms were hypothesized to be inversely related to the health-related quality of life indicators. Religious involvement, spiritual well-being and existential well-being were posited to moderate the relationship between HIV symptoms and the health-related quality of life indicators. Findings from the multivariate analysis of variance showed existential well-being to be significantly related to mental health functioning and health distress and HIV symptoms to be significantly related to mental health functioning and physical functioning. Results from the regression analyses also showed that after controlling for age, both existential well-being and HIV symptoms were significantly related to mental health functioning. Results suggest that increased symptom frequency is significantly associated with worse mental health while higher levels of existential well-being are significantly related to better mental health. No evidence was found in support of the hypothesized moderating role of religious involvement, spiritual well-being and existential well-being between HIV symptoms and health-related quality of life indicators. Research and clinical implications of these findings are discussed.

Two experiments examined growth performance and physiological measures of stress in pre- and postweaned Angus steers (313 ± 24.5 kg; n = 48/Exp.), where steers were fitted with (YD) or without (ND) an anti-suckling device (Exp. 1), or provided (YS) or not provided (NS) a grain supplement (Exp. 2) for 7 d and weaned by fenceline (FS) or total separation (TS). Steers in Exp. 1 were weighed and bled on d 0, 3, 7 10, 14, 21, and 42, and in Exp. 2, on d 0, 7, 10, 14, and 21 and provided a grain supplement on d 7-21. In Exp. 1, weight gain was not different (P = 0.74) between ND and YD steers during preweaning. The YD-FS steers lost weight (P = 0.01) by d 10 compared with YD-TS steers. Hematocrit (Hct) increased (P = 0.04) in YD but not ND steers on d 3. Neutrophil:lymphocyte ratio (N:L) increased (P < 0.01) in all steers by d 7. Cortisol values in YD-FS steers were higher (P < 0.05) compared with YD-TS steers on d 10 and 21. The ND-FS steers had higher (P = 0.04) interferon-gamma (IFN) concentrations on d 10 compared with all YD steers. Haptoglobin (HAP) values increased (P < 0.01) in all steers by d 3. The FS steers had higher (P < 0.01) ceruloplasmin (CER) values by d 10 than TS steers regardless of preweaning treatment. Ovalbumin-specific IgG increased (P < 0.01) in all steers 10 d following its administration. In Exp. 2, NS-TS steers lost weight (P < 0.01) between d 7 and 10 compared with the remaining steers. The YS steers had higher cortisol, N:L and CER on d 7 compared with NS steers. Moreover, NS steers had higher (P < 0.01) Hct on d 10 than YS steers. Based upon physiological and growth performance data, it may be concluded that use of an anti-suckling device prior to weaning does not improve the animals’ well-being and, providing a grain supplement beginning 7 d prior to weaning may temper the animals’ stress response due to weaning when total separation is employed.

This paper presents an experimental study with 47 participants on the influence of lighting on performance and well-being in an office environment. Well-being, alertness and performance were evaluated and measured in two rooms with artificial lighting and one room with day lighting. The evaluations were correlated to cortisol/melatonin saliva samples, illuminance and spectral compo-sition of the lighting. The results show day lighting to have a sustained influence on alertness and performance and it is furthermore concluded that the level of cortisol in saliva was not influenced by the illuminance and did not have an influence on performance. The participants preferred a lighting with different kinds of light sources to a more neutral lightning and gave it higher ratings for well-being.The analysis shows that comfort did not influence alertness.

Global life satisfaction is the evaluation of one’s life among important domains. Therefore, importance ratings should improve the relation between domain satisfaction and life satisfaction. However, this is not the case because studies have shown that importance ratings do not improve the model. This study examined the validity of importance and satisfaction measures using a multi-method approach. 316 participants were recruited in friendship pairs to fill out a series of questionnaires about themselves and their friend. Based on the self-informant agreement scores, there is some validity in importance and the satisfaction ratings. The importance measures for some domains also predicted people’s behavioural patterns. Indirect importance ratings were also extracted using regression and correlational analysis. In conclusion, there was also evidence for convergent validity of the direct and indirect importance measures. Therefore, people do think about the important domains to some extent when making a global life satisfaction judgment.

Numerous studies have investigated the relationship between physical activity and physiological health (e.g., Burke et al., 2006; Irwin, 2004). Less attention has been paid to the contribution of physical activity on psychological well-being (Fox et al., 2000), and more specifically eudaimonic well-being, which reflects optimal psychological functioning and development at ones maximum potential (Ryff, 1989, 1995). This study investigated the role that health-enhancing physical activity (HEPA; any form of physical activity that benefits health and functional capacity; Miilunpalo et al., 2000) plays in eudaimonic well-being, which Ryff conceptualizes in terms of six dimensions: (1) Autonomy (i.e., being self-determined and independent); (2) Environmental Mastery (i.e., having a sense of mastery and competence in managing the environment); (3) Personal Growth (i.e., having a feeling of continued development); (4) Positive Relations with Others (i.e., having warm, satisfying, and trusting relationships with others); (5) Purpose in Life (i.e., having goals and a sense of direction in life); and, (6) Self-acceptance (i.e., possessing a positive attitude toward the self).<p> Employing Ryffs (1989, 1995) perspective of eudaimonic well-being, this study explored whether or not experiencing eudaimonia during HEPA moderates the relationship between HEPA and eudaimonic well-being. Additionally, it explored whether or not the relationship between experiencing eudaimonia during HEPA and eudaimonic well-being is mediated by basic need satisfaction. Undergraduate university students (N = 524; Mage = 20.7 years) completed an online survey including the Scales of Psychological Well-Being (Ryff & Keyes, 1995), the Short Questionnaire to Assess Health-enhancing Physical Activity (Wendel-Vos et al., 2003), the Hedonic and Eudaimonic Motives for Activity scale (Huta & Ryan, 2008), and the Psychological Need Satisfaction in Exercise Scale (Wilson, Rogers, et al., 2006). While level of HEPA was not significantly related to eudaimonic well-being (r = .05, p = .24), experiencing hedonia during HEPA (i.e., enjoying oneself, experiencing pleasure; r = .40, p < .01), experiencing eudaimonia during HEPA (r = .37, p < .01), and basic need satisfaction (r = .46, p < .01) were significantly related to eudaimonic well-being. Although experiencing eudaimonia during HEPA did not moderate the relationship between HEPA and eudaimonic well-being, experiencing eudaimonia during HEPA accounted for a significant 2.2% unique variance in eudaimonic well-being beyond HEPA and experiencing hedonia during HEPA (the full model accounted for a significant 18.2% of the variance in eudaimonic well-being).<p> Furthermore, the data were consistent with a model of partial mediation in that basic need satisfaction partially accounted for the relationship between experiencing eudaimonia during HEPA and eudaimonic well-being, supporting the proposition put forth by Ryan et al. (2008) that positive psychological well-being is a result of eudaimonic living that facilitates the satisfaction of our basic psychological needs. Findings from this study suggest that what appears to be significant in the relationship between HEPA and eudaimonic well-being is not the level of activity, but rather what is experienced during the activity. Future research may explore the directionality of the relationship by examining the extent to which eudaimonic well-being influences what is experienced during activity.

American society has lost sight of one of its most valued virtues: Happiness. Research has showed that the United States is behind many other countries in the overall happiness of its citizens. Leading the world in well-being is Denmark. This paper’s aim is to explore possible factors that could be facilitating the well-being of Danish citizens, and applying them to American society. In this search, I explore universal individual factors, as well as factors that lead to the development of a culture and dispositions of its citizens. From these factors, as well as unique characteristics of both countries, I hypothesized determinates of well-being in Demark, as well as factors that are detrimental to American’s well-being. Factors for Demark include uniform cultural ideals, social equality, social programs, and unique perspectives on happiness. Conversely, the lack or low levels of these factors for Americans might attest to lower well-being. By emulating these Danish policies and ideals, the U.S. could produce happier, less stressed Americans.
