I Matter to My Friend,Therefore I am Happy: Friendship,Mattering, and Happiness

Decades of empirical research have shown that friendship experiences are an essential predictor of happiness. However, what might account for the relationship between friendship and happiness? Two studies investigated perceived mattering (Marshall, J Adolesc 24:473–490, 2001) as a mediator of the association between friendship quality and happiness. Study 1 showed that perceived mattering to one’s best friend mediated the relationship between friendship and happiness. Study 2 replicated the findings of the first study and showed that mattering in friendships accounts for the role of friendship quality in happiness across the three closest friendships of the individual. The results are discussed in terms of the theoretical importance of understanding how friendship is related to happiness.

Close Relationships and Happiness Among Emerging Adults

The present investigation examined the role of multiple close relationships (mother, father, best friend, and romantic partner, if any) in happiness among emerging adults with and without a romantic partner. The results for those without a partner (n = 152) revealed that only the relationship experiences with mother and best friend were predictive of happiness. On the other hand, the findings for those with a partner (n = 159) showed that only three factors, namely mother–child relationship quality, romantic relationship quality and conflict were predictive of happiness. The results for this group also suggested that romantic relationship quality was protective of best friendship conflict; moreover, best friendship quality did not buffer the negative impact of romantic partner conflict on happiness, suggesting a less important role of best friends in happiness. In other words, the findings suggest that when emerging adults are involved in a romantic relationship, friends’ importance in happiness might be less pronounced or not pronounced at all. The results were discussed in light of the literature and suggestions were made for future research.     

The ethics of earthquake prediction

Scientists’ responsibility to inform the public about their results may conflict with their responsibility not to cause social disturbance by the communication of these results. A study of the well-known Brady-Spence and Iben Browning earthquake predictions illustrates this conflict in the publication of scientifically unwarranted predictions. Furthermore, a public policy that considers public sensitivity caused by such publications as an opportunity to promote public awareness is ethically problematic from (i) a refined consequentialist point of view that any means cannot be justified by any ends, and (ii) a rights view according to which individuals should never be treated as a mere means to ends. The Parkfield experiment, the so-called paradigm case of cooperation between natural and social scientists and the political authorities in hazard management and risk communication, is also open to similar ethical criticism. For the people in the Parkfield area were not informed that the whole experiment was based on a contested seismological paradigm.     

The role of overt head movement and attention in persuasion

This study examined the effect of overt head movement on attitudes toward a product. In a headphones test, participants were required to listen to music and to either nod or shake their heads. Some participants listened to a CD of music; other participants listened to a CD of the same music and a persuasive message about the headphones. Overt head movement affected participants' product choice and price perception when they were presented with the music and a persuasive message. The findings are interpreted to suggest that head movement can be instrumental in participants' product evaluation if the head movement is directed or focused on the attitude object.     

Breakup Adjustment in Young Adulthood

The purpose of this study was to assess the ability of young adults to adjust to the breakup of a romantic relationship by examining the possible predictors. The sample comprised 140 women and 143 men. Simultaneous regression analysis indicated that initiator status, existence of a new partner, certainty of the reasons for the breakup, and perceived social support were significant predictors and accounted for 18% of the variance in the measure of adjustment to breakup.     

Fragility of Happiness Beliefs Across 15 National Groups

The belief that happiness is fragile—that it is fleeting and may easily turn into less favourable states—is common across individuals and cultures. However, not much is known about this belief domain and its structure and correlates. In the present study, we use multigroup confirmatory factor analysis and multilevel modelling to investigate the measurement invariance, cross-level isomorphism, predictive validity, and nomological network of the fragility of happiness scale across 15 nations. The results show that this scale has good statistical properties at both individual and cultural levels, and is associated with relevant psycho-social concepts in expected directions. The importance of the results, limitations, and potential directions for future research are discussed.     

Toward a Better Understanding of the Relationship Between Friendship and Happiness: Perceived Responses to Capitalization Attempts, Feelings of Mattering, and Satisfaction of Basic Psychological Needs in Same-Sex Best Friendships as Predictors of Happiness

Friendship is a consistent correlate of happiness, yet less is known about the associations of friendship specific experiences and feelings with happiness. In this study (n = 4,382) the roles of perceived responses to capitalization attempts, perceived mattering to and satisfaction of basic psychological needs in same-sex best friendships in happiness among men and women were investigated. Findings showed that although all of the friendship variables were positively associated with happiness to varying degrees, basic needs satisfaction emerged as the strongest predictor of happiness. Additional analyses revealed that competence need satisfaction was the most important need predicting happiness. Importantly, these findings were gender invariant. The findings were discussed in light of theory and empirical literature and suggestions were made for future research.     

Perceived autonomy support, friendship maintenance, and happiness

Decades of empirical research have shown that perceived autonomy support in close relationships is an essential correlate of happiness. However, what might account for the relationship between the 2? For this article, 4 studies (total N=1325) investigated friendship maintenance as a mediator of the association between friendship autonomy support and happiness. The first 3 studies supported the model for the best friendship of the individual when happiness was assessed with 3 different measures. The 4th study extended the findings by showing that the model was generalizable to the other close friendship of the individual. Overall, the results supported the idea that engaging in routine and strategic behaviors to maintain friendships explains how perceived autonomy support in friendships is associated with happiness. The theoretical and applied implications of the findings were discussed and suggestions for future research were made.
