Project description:ObjectiveSocial media is increasingly being used to study psychological constructs. This study is the first to use Twitter language to investigate the 24 Values in Action Inventory of Character Strengths, which have been shown to predict important life domains such as well-being.MethodWe use both a top-down closed-vocabulary (Linguistic Inquiry and Word Count) and a data-driven open-vocabulary (Differential Language Analysis) approach to analyze 3,937,768 tweets from 4,423 participants (64.3% female), who answered a 240-item survey on character strengths.ResultsWe present the language profiles of (a) a global positivity factor accounting for 36% of the variances in the strengths, and (b) each of the 24 individual strengths, for which we find largely face-valid language associations. Machine learning models trained on language data to predict character strengths reach out-of-sample prediction accuracies comparable to previous work on personality (rmedian = 0.28, ranging from 0.13 to 0.51).ConclusionsThe findings suggest that Twitter can be used to characterize and predict character strengths. This technique could be used to measure the character strengths of large populations unobtrusively and cost-effectively.

Project description:BackgroundPositive affect (PA) attenuates negative reactivity to stress; however, this adaptive function of PA is seldom studied in psychiatric conditions characterized by more extreme forms of affective responding. We tested distinct associations of PA and negative affect (NA) with anxiety reactivity in participants with social anxiety disorder (SAD)-a condition characterized by heightened NA and diminished PA-and non-SAD control subjects.MethodAdults with a principal diagnosis of SAD (n = 71) and those without a psychiatric history (n = 36) rated their PA and NA during the past week, and were exposed to a laboratory stressor wherein they delivered a video-recorded speech on a controversial topic. Anxiety reactivity was assessed in terms of anticipatory anxiety prior to the speech, and observer-rated anxiety-related behavior during the speech.ResultsAcross all participants, higher PA significantly predicted lower anticipatory anxiety and less anxiety-related behavior, beyond level of NA; lower NA significantly predicted attenuated anticipatory anxiety, but not anxiety-related behavior, beyond level of PA. The association between PA and stress reactivity was diminished for individuals with especially elevated NA, as well as for individuals with SAD compared to those without.ConclusionsPA may be protective against negative reactivity to social stress; however, theoretical models and clinical applications should consider possible interactive effects of PA and NA in modulating stress reactivity.

Project description:BackgroundThe present study aimed to develop and validate the Character Strengths Test 24 (CST24), a simple scale consisting of 24 character strengths represented by one concept word and one sentence each. Three studies were conducted to examine the validation and utility of the CST24 for future research.MethodsThree internet-based surveys were conducted in Japan to investigate the psychometric properties of the CST24. Study 1 comprised 846 adults and focused on test development, including the evaluation of well-being and strengths scales, as well as retest reliability. Study 2 involved 1137 high school students and 1101 college undergraduates, aiming to investigate the factor structure of the CST24 and reaffirm its validity by utilizing happiness and meaning in life scales. In Study 3, 524 working adults participated to explore the scale's potential for future research. This study incorporated various psychological scales, such as value orientation, moral foundation, and work-related scales, to assess the utility of the CST24.ResultsIn Study 1, the CST24 items exhibited a well-distributed response pattern, demonstrating favorable retest reliability and internal consistency. Significant positive correlations were found between the CST24 items and measures of subjective well-being, meaning in life, positive self-compassion, and knowledge or utilization of strengths. Study 2 confirmed the stability of the factor structure across diverse sample groups, consistent with prior studies utilizing larger-scale measures. Study 3 identified both core and peripheral strengths, highlighting specific strengths that made substantial contributions to well-being, value orientation, moral foundation, sense of mission, and work-related indices through multiple regression analysis.ConclusionThe findings support the reliability and validity of the CST24 as a concise assessment tool for measuring 24 character strengths. Its potential utility for screening and exploratory research warrants attention in future studies, enhancing our understanding of the role of character strengths in various domains.

Project description:The COVID-19 had negative effects on individuals and nations worldwide. However, based on literature suggesting that crises can trigger growth, we propose that it may have also triggered individuals’ character strengths development, especially among those having experienced moderate levels of difficulty during the pandemic and having received social support. The participants’ (N = 1700) 24 character strengths were assessed twice: before and during COVID-19. At the second assessment, participants also reported the level of impact COVID-19 had on their lives, and their perceived social support. MANOVA analysis revealed a general increase in character strengths, with significant – but mainly negligible or small - increases in 17 strengths: appreciation of beauty and excellence, bravery, prudence, creativity, curiosity, fairness, gratitude, honesty, hope, judgment, kindness, leadership, perspective, self-regulation, social intelligence, spirituality, and zest. Across the 24 strengths, the reported level of COVID-19’s impact (i.e., low, moderate, or high) was not associated with different changes during the pandemic. Univariate analyses showed that such changes were significant only in curiosity, forgiveness and kindness. The multivariate effect of social support on changes in character strengths was significant. Specifically, it enhanced the increase in love, prudence, curiosity, forgiveness, gratitude, honesty, hope, judgment, leadership, humility and zest during COVID-19, although the interactions effect sizes were small. The results suggest that, in the time frame examined in this study, character development processes triggered by COVID-19 were evident, yet specific changes in strengths were relatively mild. Some of these processes may have been enhanced by social support. Supplementary Information The online version contains supplementary material available at 10.1007/s10902-022-00575-6.

Project description:Acute and chronic stress are important factors in the development of mental disorders. Reliable measurement of stress reactivity is therefore pivotal. Critically, experimental induction of stress often involves multiple "hits" and it is an open question whether individual differences in responses to an earlier stressor lead to habituation, sensitization, or simple additive effects on following events. Here, we investigated the effect of the individual cortisol response to intravenous catheter placement (IVP) on subsequent neural, psychological, endocrine, and autonomous stress reactivity. We used an established psychosocial stress paradigm to measure the acute stress response (Stress) and recovery (PostStress) in 65 participants. Higher IVP-induced cortisol responses were associated with lower pulse rate increases during stress recovery (b = -4.8 bpm, p = .0008) and lower increases in negative affect after the task (b = -4.2, p = .040). While the cortisol response to IVP was not associated with subsequent specific stress-induced neural activation patterns, the similarity of brain responses Pre- and PostStress was higher IVP-cortisol responders (t[64] = 2.35, p = .022) indicating faster recovery. In conclusion, preparatory stress induced by IVP reduced reactivity in a subsequent stress task by modulating the latency of stress recovery. Thus, an individually stronger preceding release of cortisol may attenuate a second physiological response and perceived stress suggesting that relative changes, not absolute levels are crucial for stress attribution. Our study highlights that considering the entire trajectory of stress induction during an experiment is important to develop reliable individual biomarkers.

Project description:The posterior hypothalamic nucleus (PH) stimulates autonomic stress responses. However, the role of the PH in behavioral correlates of psychiatric illness, such as social and anxiety-like behavior, is largely unexplored, as is the neurochemistry of PH connectivity with limbic and neuroendocrine systems. Thus, the current study tested the hypothesis that GABAergic signaling within the PH is a critical link between forebrain behavior-regulatory nuclei and the neuroendocrine hypothalamus, integrating social and anxiety-related behaviors with physiological stress reactivity. To address this hypothesis, GABAA receptor pharmacology was used to locally inhibit or disinhibit the PH immediately before behavioral measures of social and anxiety-like behavior in rats. Limbic connectivity of the PH was then established by simultaneous co-injection of anterograde and retrograde tracers. Further, the role of PH GABAergic signaling in neuroendocrine stress responses was tested via inhibition/disinhibition of the PH. These studies determined a prominent role for the PH in the expression of anxiety-related behaviors and social withdrawal. Histological analyses revealed divergent stress-activated limbic input to the PH, emanating predominantly from the prefrontal cortex, lateral septum, and amygdala. PH projections also targeted both parvicellular and magnocellular peptidergic neurons in the paraventricular and supraoptic hypothalamus. Further, GABAA receptor pharmacology determined an excitatory effect of the PH on neuroendocrine responses to stress. These data indicate that the PH represents an important stress-integrative center, regulating behavioral processes and connecting the limbic forebrain with neuroendocrine systems. Moreover, the PH appears to be uniquely situated to have a role in stress-related pathologies associated with limbic-hypothalamic dysfunction.

Project description:Individuals, particularly those considered "hard-to-reach," often engage well with assessment tools that involve active dialogue and the co-construction of knowledge. Strengths profiling is one such tool that enables a person-centered and autonomy supportive approach to the identification of character strengths. Strength profiling is an adaptation of performance profiling used in sport psychology, which has not yet been utilized in broader psychological research or clinical practice. Supporting an individual by raising awareness of their personal character strengths is an effective and growing mechanism for promoting psychological well-being. Strengths profiling involves several stages of exploring, defining, and assessing character strengths, leading to the identification of signature strengths and goals for future development. Informed by personal construct theory, the present study explored the experiences of homeless young people living in sheltered accommodation (N = 116), when using strengths profiling at the start and end of a 10-week, strengths-based intervention. Mixed-method data was obtained from the strengths profiles, questionnaires measuring resilience, self-worth, and well-being, and diary entries. Findings revealed a rich array of character strength terminology and individual meanings. Participants found strengths profiling to be highly engaging, particularly due to their active role in strength identification, which prompted interesting and meaningful reflections on character strengths that were pertinent to them. Participants felt their signature strengths were vital protective factors within their lives and strengths profiles were correlated with resilience, self-worth, and well-being. Character strengths and resilience were also significantly and meaningfully improved pre/post-intervention, providing support for the use of strengths profiling as a tool for monitoring change in character strength perceptions. Overall, this study demonstrates the utility and versatility of strengths profiling as a new method in the discipline of positive psychology and strengths-based research and applied practice.

Project description:Objectives:Numerous studies have confirmed robust relationships between general well-being and mindfulness or character strengths, respectively, but few have examined associations between mindfulness and character strengths. Two studies were carried out to explore these relationships comprehensively in the framework of the Values in Action (VIA) classification of character strengths. Methods:In study 1, participants (N?=?1335) completed validated assessments of mindfulness and character strengths, and the relationship between the two was investigated in a broad online sample. In study 2, the effect of a mindfulness training on specific character strengths was investigated using a randomized-control design (N?=?42). Results:The results of study 1 confirmed positive relationships between mindfulness and character strengths and further identified a list of character strengths that might overlap with mindfulness-i.e., creativity, curiosity, open-mindedness, love of learning, perspective, bravery, perseverance, zest, love, social intelligence, forgiveness, self-regulation, appreciation of beauty, gratitude, hope, and spirituality. The findings of study 2 provided further support for the hypothesis that mindfulness training could help cultivate certain character strengths. Compared with participants in the waitlist control condition, those who attended an 8-week mindfulness-based training program showed significant increases in the strengths of love, appreciation of beauty, gratitude, and spirituality, and a trend toward significant increases in the strengths of zest and bravery. Conclusions:The results provide initial evidence for a mutual support model of mindfulness and character strengths.

Project description:A model on the role of character strengths in individual, collective, and species success is proffered. It is derived from viewing character strengths from a species perspective as opposed to one of individual differences/personality psychology. The history of the VIA initiative on character science is overviewed, and results to date are summarized in terms of promoting well-being, helping to accomplish aspirational intentions, and allowing the greater good of the collective to grow. "The character strengths response" is described as the response capacities that character strengths may enable for helping us fulfill the human promise of surviving, thriving, and successfully creating a next-generation so that individuals and the collective flourish while also living in harmonious balance with other species. An argument is presented that there is an urgent need for advancing population-wide psychological maturity to be better prepared to navigate the difficult decisions that accompany growing technological powers, and that the character strengths response warrants special attention of research funding to accomplish this imperative.

Project description:During interracial encounters, well-intentioned European Americans sometimes engage in subtle displays of anxiety, which can be interpreted as signs of racial bias by African American partners. In the present research, same-race and cross-race stranger dyads ( N = 123) engaged in getting-acquainted tasks, during which measures of sympathetic nervous system responses (preejection period, PEP) and heart rate variability were continuously collected. PEP scores showed that African American partners had stronger physiological linkage to European American partners who evidenced greater anxiety-greater cortisol reactivity, behavioral tension, and self-reported discomfort-which suggests greater physiological responsiveness to momentary changes in partners' affective states when those partners were anxious. European Americans showed physiological linkage to African American and European American partners, but linkage did not vary as a function of their partner's anxiety. Using physiological linkage offers a novel approach to understanding how affective responses unfold during dynamic intergroup interactions.
