A Placebo-Controlled Online Study on Potential Mediators of a Pleasure-Based Positive Psychology Intervention: The Role of Emotional and Cognitive Components

While broad evidence exists that positive psychology interventions are effective in increasing well-being, less is known about the working mechanisms behind this process. We examine the impact of subjective changes in affectivity (i.e., elicitation of positive emotions) and cognitive processes (i.e., the gaining of insights) in three variants of a pleasure-based placebo-controlled online intervention (N = 509 adults). The variants were designed that they have (1) a cognitive focus, (2) an emotional focus, or (3) both cognitive and emotional foci. We assessed happiness and depressive symptoms before the intervention, immediately after the intervention, and at follow-ups after two weeks, one month, and three months, and collected subjective ratings on potential working mechanisms. Findings indicated that both variants with a cognitive focus increased happiness in comparison to the control condition, whereas only those interventions that fostered the experience of positive emotions reduced depressive symptoms. Positive emotions mediated the effects of the intervention on happiness and depressive symptoms, whereas insights only mediated the effects on happiness. The findings support the important role of positive emotions in positive interventions and provide new evidence for the relevance of cognitive changes in such interventions.     

Model Predictive Impedance Control: A Model for Joint Movement

Impedance control has been suggested as the strategy employed by the central nervous system to control human postures and movements. A realization of this strategy is presented that uses a model predictive control algorithm as a higher motor controller. External disturbances are explicitly included in the model. The combination of 3 key factors-joint impedance control, model predictive controller, and external disturbance input-forms the basis for the generality of this model. The model was applied to 3 different types of joint movements: a tracking movement with an unpredicted disturbance, a rhythmic movement, and an unstable biped model of human walking. Computer simulation results showed excellent performance of the model in all 3 cases for optimal values of active joint impedances and an exact match between the musculoskeletal system and the model internal to the model predictive controller. The controller was also able to maintain acceptable performance in the presence of a 25% mismatch between the musculoskeletal system and its internal model.     

Team roles: Their relationships to character strengths and job satisfaction

Well-functioning teamwork has frequently been linked to increased work satisfaction and performance. However, there is a paucity of research on the different types of roles in teams. Recently, a new model of role behavior in teams was proposed (comprising seven such team roles: Idea creator, information gatherer, decision-maker, implementer, influencer, energizer, and relationship manager), but an assessment instrument was lacking so far. The present study describes the construction of an instrument for the assessment of these roles in two samples (N = 291 and 274) and examines their relationships with character strengths and job satisfaction. Results show that the team roles are positively related to job satisfaction and most character strengths. The findings support the important role of character strengths in work-related settings and lay ground for further studies on team roles.     

The Subjective Assessment of Accomplishment and Positive Relationships: Initial Validation and Correlative and Experimental Evidence for Their Association with Well-Being

In his Authentic Happiness Theory, Seligman describes three orientations that lead to happiness: The life of pleasure, the life of engagement, and the life of meaning (in Authentic happiness, Free Press, New York, 2002). The Orientations to Happiness Questionnaire (OTH; Peterson et al. in J Happiness Stud 6:25–41, 2005) has been developed as a subjective measure for these three orientations. In 2011, Seligman revised his theory and added two new components; i.e., positive relationships and accomplishment. These five are the basic tenets of his well-being theory. The present set of studies describes the construction and initial validation of two short scales for the subjective assessment of the endorsement of positive relationships and accomplishment. Their relation with the OTH-scales is also tested. Study 1 describes the scale construction and provides evidence for the factorial, convergent and divergent validity in three samples (n = 233, n = 336, and n = 125). Study 2 showed that the new scales have high test–retest reliabilities over a period of 1, 3, and 6 months (r = .68–.78), respectively. Study 3 examines the malleability of positive relationships and accomplishment in an intervention study that shows that the scores of both new scales increase in the intervention condition. Overall, the three studies show that the new scales have satisfactory psychometric properties—also when used together with the OTH-scales—and possible applications are discussed.     

Character Strengths – Stability,Change, and Relationships with Well-Being Changes

Character strengths are positively valued personality traits that are assumed to be stable across time and situations, but also malleable due to cultivation or deliberate intervention. Also, studies showed that character strengths are robustly related to well-being. Consequently, character strengths have often been used in interventions aimed at increasing well-being. However, the stability of character strengths and the longitudinal relationships with well-being are widely unexplored: First, previous reports on the stability of character strengths have mainly focused on one assessment instrument only and second, they did not consider other indicators of stability (and malleability) besides rank-order stability, (i.e., mean-level stability). In this longitudinal study, we assessed character strengths and well-being at two time points and examined the stability and malleability of character strengths and the convergence of changes in character strengths and well-being by means of correlation analyses. Two samples (n₁ = 601, n₂ = 1162) completed different measures of character strengths and instruments for the assessment of well-being, ill-being, and health within up to three and a half years. Results showed that character strengths are stable over longer time periods (test-retest reliabilities ranging from r_tt = .60–.83) and that relationships between changes in strengths and well-being are highly parallel to what has been reported in cross-sectional studies (strongest relationships for zest, hope, curiosity, and love). Furthermore, results suggest that some strengths, most predominantly humor, but also spirituality and prudence might be more amenable for change than others. These results might bear important information for selecting character strengths in interventions.

     

Character Strengths and Life Satisfaction in Later Life: an Analysis of Different Living Conditions

The aim of this study was to explore the role of character strengths and their associations to life satisfaction in older people. We were interested in studying several transitions that are specific for older people: aging, retirement, living alone, and being widowed. We examined the relationships of these demographic characteristics and living conditions with character strengths and studied their effects on the association of character strengths with life satisfaction. In a cross-sectional analysis, 15,598 older adults (aged 46–93 years) who had completed measures on character strengths, life satisfaction, and demographic characteristics and living conditions were selected from an existing database. Overall, analyses revealed positive associations of most character strengths with age, and higher scores in most character strengths for the employed (vs. the retired) and those living with a partner (vs. those living alone), while only few relationships with being widowed (vs. being married) were observed. Further, the contribution of character strengths to life satisfaction generally decreased slightly with age, but increased for certain character strengths, such as modesty or prudence. Also, stronger relationships between several character strengths and life satisfaction were found for retired people and those living alone, while being widowed did not affect these relationships. The results demonstrate how character strengths might contribute to the life satisfaction of older adults in various living conditions and thereby offer a starting point for strengths-based programs in later life.

Strength-Based Positive Interventions: Further Evidence for Their Potential in Enhancing Well-Being and Alleviating Depression

The impact of nine strengths-based positive interventions on well-being and depression was examined in an Internet-based randomized placebo-controlled study. The aims of the study were to: (1) replicate findings on the effectiveness of the gratitude visit, three good things, and using character strengths interventions; (2) test variants of interventions (noting three good things for 2 weeks; combining the gratitude visit and three good things interventions; and noting three funny things for a week); and (3) test the effectiveness of the counting kindness, gift of time, and another door opens-interventions in an online setting. A total of 622 adults subjected themselves to one of the nine interventions or to a placebo control exercise (early memories) and thereafter estimated their degrees of happiness and depression at five times (pre- and post-test, 1-, 3-, and 6 months follow-up). Eight of the nine interventions increased happiness; depression was decreased in all groups, including the placebo control group. We conclude that happiness can be enhanced through some “strengths-based” interventions. Possible mechanisms for the effectiveness of the interventions are discussed.     

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.
