Positive psychology interventions in people aged 50–79 years: long-term effects of placebo-controlled online interventions on well-being and depression

Objectives: Various positive psychology interventions have been experimentally tested, but only few studies addressed the effects of such activities in participants aged 50 and above. Method: We tested the impact of four self-administered positive psychology interventions in an online setting (i.e., gratitude visit, three good things, three funny things, and using signature strengths in a new way) on happiness and depressive symptoms in comparison with a placebo control exercise (i.e., early memories). A total of 163 females aged 50–79 tried the assigned interventions or the placebo control exercise for one week and completed measures on happiness and depressive symptoms at five times (pre- and post-test, 1, 3, and 6 months). Results: Three out of the four interventions (i.e., gratitude visit, three good things, and using signature strengths in a new way) increased happiness, whereas two interventions (three funny things and using signature strengths in a new way) led to a reduction of depressive symptoms on at one post-measure. Conclusion: Positive psychology interventions yield similar results for people aged 50 and above as for younger people. The dissemination of such interventions via the Internet offers a valuable opportunity for older age groups as well.

Strengths-based positive psychology interventions: a randomized placebo-controlled online trial on long-term effects for a signature strengths- vs. a lesser strengths-intervention

Recent years have seen an increasing interest in research in positive psychology interventions. There is broad evidence for their effectiveness in increasing well-being and ameliorating depression. Intentional activities that focus on those character strengths, which are most typical for a person (i.e., signature strengths, SS) and encourage their usage in a new way have been identified as highly effective. The current study aims at comparing an intervention aimed at using SS with one on using individual low scoring (or lesser) strengths in a randomized placebo-controlled trial. A total of 375 adults were randomly assigned to one of the two intervention conditions [i.e., using five signature vs. five lesser strengths (LS) in a new way] or a placebo control condition (i.e., early memories). We measured happiness and depressive symptoms at five time points (i.e., pre- and post-test, 1-, 3-, and 6-months follow-ups) and character strengths at pre-test. The main findings are that (1) there were increases in happiness for up to 3 months and decreases in depressive symptoms in the short term in both intervention conditions; (2) participants found working with strengths equally rewarding (enjoyment and benefit) in both conditions; (3) those participants that reported generally higher levels of strengths benefitted more from working on LS rather than SS and those with comparatively lower levels of strengths tended to benefit more from working on SS; and (4) deviations from an average profile derived from a large sample of German-speakers completing the Values-in-Action Inventory of Strengths were associated with greater benefit from the interventions in the SS-condition. We conclude that working on character strengths is effective for increasing happiness and discuss how these interventions could be tailored to the individual for promoting their effectiveness.

Toward a Better Understanding of What Makes Positive Psychology Interventions Work: Predicting Happiness and Depression From the Person × Intervention Fit in a Follow‐Up after 3.5 Years

BACKGROUND Robust evidence exists that positive psychology interventions are effective in enhancing well-being and ameliorating depression. Comparatively little is known about the conditions under which they work best. Models describing characteristics that impact the effectiveness of positive interventions typically contain features of the person, of the activity, and the fit between the two. This study focuses on indicators of the person × intervention fit in predicting happiness and depressive symptoms 3.5 years after completion of the intervention. METHODS A sample of 165 women completed measures for happiness and depressive symptoms before and about 3.5 years after completion of a positive intervention (random assignment to one out of nine interventions, which were aggregated for the analyses). Four fit indicators were assessed: Preference; continued practice; effort; and early reactivity. RESULTS Three out of four person × intervention fit indicators were positively related to happiness or negatively related to depression when controlled for the pretest scores. Together, they explained 6 per cent of the variance in happiness, and 10 per cent of the variance of depressive symptoms. CONCLUSIONS Most tested indicators of a person × intervention fit are robust predictors of happiness and depressive symptoms-even after 3.5 years. They might serve for an early estimation of the effectiveness of a positive intervention.

What good are character strengths beyond subjective well-being? The contribution of the good character on self-reported health-oriented behavior, physical fitness, and the subjective health status

Character strengths were tested in relation to subjective (life satisfaction) and physical (self-evaluated health and physical fitness) well-being (440 adults). Health-behaviors and the mediating role of health-behaviors in explaining the relationship between character and well-being were also considered. Emotional, intellectual strengths and strengths of the heart were positively associated with life satisfaction and physical fitness. Emotional strengths correlated positively with the self-evaluation of feeling healthy. All strengths (except for modesty and religiousness) were related to health-behaviors; e.g. healthy eating and watching ones food consumption were associated with self-regulation and intellectual strengths. Health behaviors partially mediated the relation of broader strengths factors on subjective and physical well-being. The largest indirect effects were found for leading an active way of life. The study suggests that there are positive relations between character strengths and subjective but also physical well-being. Furthermore, potential mechanisms, which might account for these relations (i.e. health-behaviors) are assessed.

Humor-based online positive psychology interventions: A randomized placebo-controlled long-term trial

While correlational evidence exists that humor is positively associated with well-being, only few studies addressed causality. We tested the effects of five humor-based activities on happiness and depression in a placebo-controlled, self-administered online positive psychology intervention study (N = 632 adults). All of the five one-week interventions enhanced happiness, three for up to six months (i.e. three funny things, applying humor, and counting funny things), whereas there were only short-term effects on depression (all were effective directly after the intervention). Additionally, we tested the moderating role of indicators of a person × intervention-fit and identified early changes in well-being and preference (liking of the intervention) as the most potent indicators for changes six months after the intervention. Overall, we were able to replicate existing work, but also extend knowledge in the field by testing newly developed interventions for the first time. Findings are discussed with respect to the current literature.

Addressing the role of personality, ability, and positive and negative affect in positive psychology interventions: Findings from a randomized intervention based on the authentic happiness theory and extensions

The present study explores the role of personality, ability, and affect in a randomized, group-based positive psychology intervention program based on Seligman’s authentic happiness theory and extensions. A total of 100 adults (M = 45.7, SD = 12.8) were randomly assigned to the 12-week intervention program (five training sessions) or a waiting list control group. The intervention consisted of basic information, group activities, and homework assignments. Participants in the intervention group demonstrated higher levels of happiness, pleasure, and engagement after completion of the program. Baseline levels of psychometric intelligence moderated the intervention effectiveness (greater effects for those higher in reasoning, vocabulary, and general intelligence). There were no effects for the big five personality traits. Finally, increases in positive affect before and after the homework assignment were associated with greater levels of happiness after the program. The relevance of these findings for the development of new programs is discussed.

Character and dealing with laughter: the relation of self- and peer-reported strengths of character with gelotophobia, gelotophilia, and katagelasticism.

ABSTRACT We hypothesized that gelotophobia (the fear of being laughed at), gelotophilia (the joy of being laughed at), and katagelasticism (the joy of laughing at others) relate differently to character strengths. In Study 1 (N = 5,134), self-assessed gelotophobia was primarily negatively related to strengths (especially to lower hope, zest, and love), whereas only modesty yielded positive relations. Gelotophilia demonstrated mainly positive relations with humor, zest, and social intelligence. Katagelasticism existed widely unrelated from character strengths with humor demonstrating the comparatively highest coefficients. Study 2 consisted of N = 249 participants who provided self- and peer-ratings of strengths and self-reports on the three dispositions. The results converged well with those from Study 1. When comparing self- and peer-reports, those higher in gelotophobia under-estimated and those higher in gelotophilia over-estimated their virtuousness, whereas those higher in katagelasticism seemed to have a realistic appraisal of their strengths. Peer-rated (low) hope and modesty contributed to the prediction of gelotophobia beyond self-reports. The same was true for low modesty, creativity, low bravery, and authenticity for gelotophilia and for low love of learning regarding katagelasticism. Results suggest that there is a stable relation between the way people deal with ridicule and laughing and their virtuousness.

Who Benefits From Humor-Based Positive Psychology Interventions? The Moderating Effects of Personality Traits and Sense of Humor

The evidence for the effectiveness of humor-based positive psychology interventions (PPIs; i.e., interventions aimed at enhancing happiness and lowering depressive symptoms) is steadily increasing. However, little is known about who benefits most from them. We aim at narrowing this gap by examining whether personality traits and sense of humor moderate the long-term effects of humor-based interventions on happiness and depressive symptoms. We conducted two placebo-controlled online-intervention studies testing for moderation effects. In Study 1 (N = 104) we tested for moderation effects of basic personality traits (i.e., psychoticism, extraversion, and neuroticism) in the three funny things intervention, a humor-based PPI. In Study 2 (N = 632) we tested for moderation effects of the sense of humor in five different humor-based interventions. Happiness and depressive symptoms were assessed before and after the intervention, as well as after 1, 3, and 6 months. In Study 2, we assessed sense of humor before and 1 month after the intervention to investigate if changes in sense of humor go along with changes in happiness and depressive symptoms. We found moderating effects only for extraversion. Extraverts benefitted more from the three funny things intervention than introverts. For neuroticism and psychoticism no moderation effects were found. For sense of humor, no moderating effects were found for the effectiveness of the five humor-based interventions tested in Study 2. However, changes in sense of humor from pretest to the 1-month follow-up predicted changes in happiness and depressive symptoms. Taking a closer look, the playful attitude- and sense of humor-subscales predicted changes in happiness and depression for up to 6 months. Overall, moderating effects for personality (i.e., extraversion) were found, but none for sense of humor at baseline. However, increases in sense of humor during and after the intervention were associated with the interventions’ effectiveness. Thus, we found humor-based interventions to be equally suited for humorous and non-humorous people, but increases in the sense of humor during the intervention phase could serve as an indicator whether it is worth continuing the intervention in the long-term.

The European Football Championship as a Positive Festivity: Changes in Strengths of Character Before, During, and After the Euro 2008 in Switzerland

This chapter presents an interesting and innovative quantitative study on the domain of sports, namely, addressing the changes encountered in character strengths of Switzerland citizens, after a collective festivity, the European Football Championship of 2008, and when Switzerland was the host country. The authors, Rene T. Proyer, Fabian Gander, Sara Wellenzohn, and Willibald Ruch, explore the interesting idea of malleability of strengths at the national level, in this case in a complete different direction of other studies regarding the impact of dramatic or shocking events affecting a whole nation. The discussion of conflicting results contributes to a debate regarding methodological difficulties and future directions.
