Gratitude in Context: Proposing the Dyadic Process Model of Interpersonal Gratitude

ABSTRACTResearch has suggested that the quality of gratitude exchanges varies, with some exchanges resulting in positive outcomes and others resulting in null and negative outcomes for intimates. However, a current conceptual model outlining the conditional nature of interpersonal gratitude exchanges is lacking within the literature. In this paper, we introduce the Dyadic Process Model of Interpersonal Gratitude, an updated conceptual model that delineates the boundary conditions of interpersonal gratitude exchanges. Using the model, we propose that the benefits associated with interpersonal gratitude expressions depend on the context in which gratitude operates, articulating the influence of communication factors and contextual factors on interpersonal gratitude exchange outcomes. Drawing from the Dyadic Process Model of Interpersonal Gratitude, we provide implications for future research and gratitude‐based interventions.

Effects of a video-feedback intervention on parenting behavior and state anxiety in mothers of children with neurodevelopmental disabilities

Neurodevelopmental disability (ND) poses a significant challenge to infants' socio-emotional and cognitive development, as well as to caregiving dynamics, such as parental sensitivity and mother-infant interaction. Prior research highlights the crucial role of early parenting support interventions in enhancing parental behaviors, serving as a protective developmental factor for children at risk for or diagnosed with ND. This single-cohort, multicentric study aims to evaluate the efficacy of early video-feedback intervention (VFI) in improving maternal parenting behaviors. Thirty-four mothers with their children diagnosed with ND participated in the study. Different dimensions of parenting behavior (i.e., affection, responsiveness, encouragement, teaching) were assessed during 10-minute mother-infant interactions, both before (T0) and after (T1) completing six weekly VFI sessions. Additionally, mothers completed standardized questionnaires assessing parenting stress, anxiety, and depressive symptoms. The results indicated significant improvements in maternal responsiveness, encouragement, and teaching following the intervention. Furthermore, mothers reported a state anxiety reduction at T1. Additionally, higher scores in affection and responsiveness were correlated with reduced maternal stress. These findings support the utility of VFI as a valuable tool for enhancing positive parenting skills in the context of ND, and provide insights into the dyadic processes through which parenting behaviors may promote socio-emotional and cognitive development in children with ND.

Mother-infant interactive processes and infant behavioral and vagal stress recovery: Associations at 3, 6, and 9 months of age.

Mother-infant interactive processes, including matching social behaviors and repairing interactive ruptures, are proposed to foster infant stress functioning. However, little is known about the extent to which the concurrent relations between these dyadic processes and infant behavioral and vagal stress recovery change over the first year of life. In this study, 116 mother-infant dyads (55 girls) from a midwestern city in the United States completed the still-face paradigm at 3, 6, and 9 months. Using microcoding of infant and maternal behaviors (i.e., facial expressions, vocalizations, and gaze directions), we defined two dyadic states (positive match and mismatch) and measured dyadic matching as a composite of (a) the proportion of positive match and (b) latency to interactive repair (i.e., the average duration of mismatches), for the play and reunion episode, separately, at each time point. Infant behavioral and vagal stress recovery were assessed as the proportion of social engagement during the reunion episode and increases in respiratory sinus arrhythmia from the still-face to reunion episodes, respectively. At 6 and 9 months, higher levels of dyadic matching during the play episode were related to better infant behavioral and vagal stress recovery, controlling for matching during the reunion episode. At 3 months, the relation only emerged for infant behavioral stress recovery. These findings suggest that the dynamics of mother-infant interaction may play a key role in infant stress recovery, particularly during the second half of the first year when infants become more actively engaged in social interactions and their vagal systems become more mature.

Do commitment and asset specificity serve as the double-edged sword to assist co-production in enhancing value co-creation? A dyadic approach in Taiwan

PurposeValue, also known as co-creation, is recognized as the outcome of collaborative efforts between both parties. However, knowledge is currently limited regarding the motivations and mechanisms driving customers to engage in co-production and value co-creation. Therefore, the current study aims to investigate co-production in enhancing value co-creation. Previous research has predominantly explored the linear effects of commitment and asset specificity on co-production. To expand on this foundation, our study goes a step further by including the potential quadratic effects of commitment and asset specificity on co-production. Although moderate levels of commitment and asset specificity may enhance co-production, higher levels are implied to possibly impede it. Considering that co-production requires collaboration between customers and service employees, this study includes the characteristics of service employees, such as self-monitoring and self-efficacy, identifying their moderating roles in aiding active co-production and ultimately enhancing the value co-creation.Design/methodology/approachWe employed linear, nonlinear and hierarchical moderated regression analysis to test our hypotheses.FindingsOur findings provide evidence for the positive linear effects and negative quadratic effects between commitment, asset specificity and co-production. The inverted-U relationships suggest an existing optimal commitment and asset specificity that maximize co-production. Results also suggest that co-production influences value co-creation and self-efficacy and self-monitoring positively moderates the relationship between co-production and value co-creation.Originality/valueBy applying the core provisions of S-D logic, this study contributes to marketing literature by analyzing the dyadic process of co-production. Dyadic data collection from both customers and service employees provides a comprehensive understanding of the co-production process, allowing academics to recognize service employees’ self-efficacy and self-monitoring that contribute to effective co-production and value co-creation in service processes.

Interpersonal emotion regulation and depressive symptoms in parent-adolescent dyads: A daily-diary investigation.

Deficient parental extrinsic interpersonal emotion regulation (IER, how people regulate others' emotions) is a known risk factor for adolescent depression. Although IER and depression development are transactional, dyadic processes, previous work has almost exclusively focused on how parental IER is associated with adolescent depression. The association between parental IER and adolescent depression, and the associations between adolescent IER and adolescent and parental depression have received little attention. Moreover, most studies have focused on the regulation of negative but not positive affect. We address these gaps by examining associations between parent and adolescent IER and depressive symptoms using the actor-partner interdependence model framework. For 28 days, 112 parent-adolescent dyads (12-18-year-old adolescents) completed a dyadic daily diary, reporting their own depressive symptoms and IER strategies employed in response to dyad members' positive and negative affect. Our results, based on 5,442 data points, show that the use of positive- and negative-affect-worsening IER is associated with more depression in the regulator (be it parent or adolescent). Surprisingly, parents' use of more negative-affect-improving IER was associated with higher levels of their own and adolescents' depression. Finally, adolescents' use of positive-affect-improving IER was associated with their own decreased depression. Overall, parents (vs. adolescents) used more negative- and positive-affect-improving extrinsic IER, whereas adolescents used more positive-affect-worsening extrinsic IER. Our results highlight the importance of using dyadic designs in studying depression and IER, as well as the need to consider who is regulating, the valence of the affect regulated, and the type of strategy used.

Minority stress and relationship satisfaction in same‐sex couples: A meta‐analysis

AbstractObjectiveThe present study conducted a meta‐analysis to synthesize the associations between sexual minority stress and relationship satisfaction, as well as to examine actor and partner effects.BackgroundSexual minority individuals in same‐sex couples experience various distinct and chronic stressors related to their stigmatized identities and romantic relationships, and these stressors negatively impact relationship satisfaction. Although there have been two meta‐analyses that sought to examine these influences, some fundamental questions remain unanswered. In particular, the roles of dyadic processes and different types of sexual minority stressors remain unclear.MethodA comprehensive search identified 67 studies with 147 effect sizes representing 24,542 individuals.ResultsThe results revealed a significant small association (r = −.100 to −.188) between sexual minority stressors and relationship satisfaction. Internalized stressors were more strongly associated with relationship satisfaction than other types of sexual minority stressors (e.g., prejudice events and concealment). Dyadic analyses demonstrated a significant actor effect of concealment, experiencing prejudice events, and internalized stressors on relationship satisfaction, with the largest effect size for concealment effects.ConclusionThese findings suggest that sexual minority stressors could potentially contribute to same‐sex relational problems. They also underscore the importance of interdependence (both partners' responses as well as their interaction with sexual minority stressors). This understanding may be instrumental in shaping prevention strategies.ImplicationsThe meta‐analysis emphasizes the nuanced impact of sexual minority stressors on same‐sex relationship satisfaction, highlighting the importance of targeted interventions. It underscores the role of dyadic processes, emphasizing the significance of both partners' responses and interactions with stressors in developing effective prevention strategies for healthier same‐sex relationships.

Relationship commitment regulation: Influencing a partner's commitment to achieve one's commitment goals

AbstractWe introduce a model of relationship commitment regulation, which describes how romantic partners might use empirically‐validated antecedents of commitment level strategically to influence a partner's commitment toward their relationship based on certain commitment goals they have for the relationship. People are generally aware of and relatively accurate with respect to knowing their partner's level of commitment and also have preferences regarding their desired level. We summarize key antecedents of commitment level (i.e., satisfaction level, alternative quality, investment size, future plans, and subjective norms) and then describe how each can be manipulated via relationship maintenance activities to move a partner's commitment level up or down, or maintained at a desired current level. Collectively, the model provides a strategic roadmap for actions one can take to foster desired commitment in one's partner and provides insight into the dyadic processes and outcomes of relationship maintenance.

Heterosexual couples' initial role and outcome expectations as predictors of the therapeutic alliance and relationship satisfaction prior to the fourth session.

We sampled routinely collected measures of role and outcome expectations, the expanded therapeutic alliance, and relationship satisfaction completed by 253 heterosexual couples seen by 35 therapists in the Marriage and Family Research Practice Network (Johnson et al., 2017) and investigated these variables as interdependent dyadic processes using the latent congruence model (Cheung, 2009) and the mediated actor-partner interdependence model (Ledermann et al., 2011). Taken together, we found a direct association between a couple's mean role and outcome expectation scores at Session 1 and individual partners' alliance perceptions at Session 3. Further, men rated the alliance more favorably when their outcome expectations were higher and the partners' outcome expectations were less discrepant. In terms of role expectations, both men and women began therapy expecting to be more actively engaged in the process than their partner. Whereas women rated the alliance more favorably when they had high role expectations for their partner as well as themselves, men rated the alliance more favorably when they had high expectations for their female partner's engagement in the therapy. Notably, alliance at Session 3 did not mediate the association between initial expectations and Session 4 relationship satisfaction due to a strong association (r = 0.85) between relationship satisfaction rated prior to Sessions 1 and 4. In other words, although the best predictor of relationship status before the fourth session was how the relationship was perceived before couple therapy began, men's and women's initial role and outcome expectations were important contributors to the early alliance.

The Relationship between Addictive Use of Short-Video Platforms and Marital Satisfaction in Older Chinese Couples: An Asymmetrical Dyadic Process.

Increasing evidence indicates that the addictive use of social media can have a detrimental effect on marital satisfaction, due mainly to the decrease in time and focus given to one's spouse. However, the impact of social media use among older couples remains under-investigated, and the research that does exist relies on individual-level data that do not allow the exploration of the dynamics between the dyadic partners. Therefore, the present study focused on older adults' use of short-video platforms, as these have been shown to be particularly addictive for older adults. A sample of 264 older couples was gathered (meanage = 68.02, SD = 8.68), and both spouses completed surveys reporting addictive use of short-video platforms, negative emotions, and marital satisfaction. Using an actor-partner interdependence model, we found an asymmetrical dyadic process in that the addictive use of short-video platforms by the wives was not only related to their own negative emotions, but also those of their spouse, as well as to decreased marital satisfaction. Meanwhile, addictive use by the husbands seemed to relate only to their own increased negative emotions, as well as to decreased marital satisfaction. Together, the findings from this study reveal dyadic dynamics with delineated pathways through which the addictive use of short-video platforms can damage older couples' interactive processes and marital satisfaction.

Physiological synchrony in supportive discussions: An examination of co-rumination, relationship type, and heterogeneity.

During times of stress, we look to close others for support. Social support conversations are critical for relationship maintenance and well-being. Yet, certain ways of talking about problems-such as co-ruminating-can exacerbate stress. Since social support and co-rumination are both dyadic processes, it is important to examine physiological responses during these conversations in a dyadic manner. Little research has examined physiological synchrony of the sympathetic nervous system (SNS) during social support conversations or co-ruminative conversations. The current research capitalizes on an experimental manipulation of co-rumination using a sample of close friends (147 dyads) and romantic partners (113 dyads) to examine physiological covariation in the context of support. Across both samples, dyads exhibited significant physiological covariation in pre-ejection period reactivity (PEP). Contrary to our hypothesis, dyads in the co-rumination condition did not show more covariation. Close friend dyads did, however, exhibit more covariation as compared to romantic dyads. We also found significant variability in physiological covariation across dyads, with a minority of dyads exhibiting negative covariation of PEP reactivity. The homogeneity of the samples limits the generalizability of the findings and highlights the need for more diverse samples in future work. These findings underline the need for further exploration into the mechanisms that contribute to distinct patterns of physiological synchrony, the conditions in which negative synchrony occurs, and what predicts especially strong positive synchrony. This work extends our understanding of physiological synchrony of the sympathetic nervous system during support conversations and emphasizes the importance of considering heterogeneity in physiological processes.

The role of maternal emotional expressivity in maternal marital satisfaction and adolescents' depressive symptoms among Chinese families: Moderated by family socioeconomic status

The present study aims to investigate the complex interplay among three family factors: maternal marital satisfaction, maternal emotional expressivity, and family socioeconomic status, and their impact on adolescent depression in Chinese families. A total of 542 Chinese adolescents and their mothers from diverse socioeconomic backgrounds completed the survey. The data revealed that higher maternal marital satisfaction correlated with more positive emotional expressivity and less negative emotional expressivity. Both types of maternal emotional expressivity were associated with depressive symptoms in adolescents. Moreover, both maternal positive and negative emotional expressivity mediated the relationship between maternal marital satisfaction and adolescents’ depressive symptoms. Notably, the mediating role of maternal negative expressivity was only evident when the family’s socioeconomic status was moderate to high. These findings underscore the important role played by maternal emotional expressivity and family socioeconomic status in the dyadic processes between the marital relationship of mothers and the emotional well-being of adolescents in Chinese families. The present study also indicates potential targets for parenting interventions aimed at promoting the mental health of adolescents.

Same-Day and Next-Day Associations Between Relational Factors and Intimate Partner Violence in Young Adult Couples.

The prevalence of intimate partner violence (IPV) is high, with young adults at increased risk. IPV is largely understood as a dyadic process, as it involves both partners and is inherently influenced by the behaviors of both partners. The objective of this study was to examine the proximal influence of relationship satisfaction and conflict on same-day and nextday IPV perpetration among young adult couples. This study used data from young adult couples (N = 172) who completed a 60-day daily-diary design. The Actor Partner Interdependence Model was used to examine whether within- and between-person levels of relationship satisfaction and conflict were associated with same-day and next-day IPV perpetration. Results suggest that high levels of one's own and one's partner's relationship satisfaction was associated with low levels of same-day and next-day psychological IPV. For women, but not men, high levels in their own and their partner's relationship satisfaction were associated with low levels in same-day physical IPV perpetration. Conversely, high levels in one's own and their partner's conflict was associated with high levels of same-day psychological IPV perpetration. For women, but not men, high levels in their partner's conflict were associated with high levels of same-day physical IPV perpetration. Results suggest that relationship dissatisfaction and conflict may be proximal risk factors for IPV perpetration, particularly psychological IPV perpetration, implying these factors may be effective targets for prevention and intervention.

How Do College Students Perceive Their Partner Responds to Them When They Refuse Sexual Activity?

Refusal communication is a dyadic process, with one person communicating a refusal and another person responding. To enhance our understanding of this process, we surveyed college students to assess their interpretation of their partners' responses when they declined vaginal-penile sexual activity. In an online survey, participants were prompted to describe their partners' reactions when participants refused their partner's vaginal-penile sex initiation. Through content analysis, three themes were present: (1) partner accepted the refusal, (2) partner experienced negative emotions, (3) partner ignored their refusals. Participants frequently reported their refusals were accepted. Sexual assault prevention initiatives should work to normalize refusal communication.

Construct Validity Testing of the Provider Co-Management Index to Measure Shared Care in Provider Dyads.

Co-management encompasses the dyadic process between two healthcare providers. The Provider Co-Management Index (PCMI) was initially developed as a 20-item instrument across three theory-informed subscales. This study aimed to establish construct validity of the PCMI with a sample of primary care providers through exploratory and confirmatory factor analyses. We conducted a cross-sectional survey of primary care physicians, nurse practitioners, and physician assistants randomly selected from the IQVIA database across New York State. Mail surveys were used to acquire a minimum of 300 responses for split sample factor analyses. The first subsample (derivation sample) was used to explore factorial structure by conducting an exploratory factor analysis. A second (validation) sample was used to confirm the emerged factorial structure using confirmatory factor analysis. We performed iterative analysis and calculated good fit indices to determine the best-fit model. There were 333 responses included in the analysis. Cronbach's alpha was high for a three-item per dimension scale within a one-factor model. The instrument was named PCMI-9 to indicate the shorter version length. This study established the construct validity of an instrument that scales the co-management of patients by two providers. The final instrument includes nine items on a single factor using a 4-point, Likert-type scale. Additional research is needed to establish discriminant validity.

Unpacking the relationship between shared decision-making and decisional quality, decision to screen, and screening completion in lung cancer screening

ObjectivesLung cancer screening is a complex and individualized decision. To understand how best to support patients in this decision, we must understand how shared decision-making is associated with both decisional and behavioral outcomes. MethodsObservational cohort study combining patient survey data with electronic health record data of lung screening-eligible patients who recently engaged in a shared decision-making discussion about screening with a primary care clinician. ResultsUsing multivariable analysis (n = 529), factors associated with higher lung cancer screening decisional quality include higher knowledge (OR = 1.33, p < .0001), lower perceived benefits (OR = 0.90, p = .0004), higher perceived barriers (OR = 1.07, p < .0001), higher self-efficacy (OR = 1.13, p < .0001), and higher levels of perceiving the discussion was shared (OR = 1.04, p < .0001). Factors associated with the patient’s decision to screen include older age (OR = 1.12, p = .0050) and higher self-efficacy (OR = 1.11, p = .0407). Factors associated with screening completion included older age (OR = 1.05, p = .0050), higher knowledge (OR = 1.24, p = .0045), and higher self-efficacy (OR = 1.12, p = .0003). ConclusionsShared decision-making in lung cancer screening is a dyadic process between patient and clinician. As we continue to strive for high-quality patient-centered care, patient decision quality may be enhanced by targeting key factors such as high-quality knowledge, self-efficacy, and fostering a shared discussion to support patient engagement in lung cancer screening decisions.

КОНЦЕПЦИЯ ХАРИЗМАТИЧЕСКОГО ЛИДЕРСТВА: СОВРЕМЕННОЕ СОСТОЯНИЕ И ПЕРСПЕКТИВЫ РАЗВИТИЯ

The article considers modern issues in the study of charismatic leadership. It notes theoretical limitations of the study of charismatic leadership: the uncertainty of charisma and the factors of its formation, the uncertainty of the processes of influence of the leader on followers, the emphasis on dyadic processes, ignoring the dynamics of the development of charismatic leadership. It also considers as newest concept, the theory of charisma as a value-based symbolic and emotional signal of a leader. The author emphasizes the role of moral emotions and embodied signals associated with bodily experience in the formation of charismatic leadership. She shows that personal predictors of charisma are cognitive abilities and the Big Five factors. Charismatic leadership is found to foster growth in organizing the civil society, in the group and organizational effectiveness. There is also an indication of the importance of the charisma concept as a symbolic and emotional signal for the practice of management and personnel management. Directions for further study of charismatic leadership are outlined: expanding qualitative research, using experimental strategies, searching for objective indicators of charisma, identifying personal predictors of charisma, including gender characteristics, Dark Triad traits, non-academic types of intelligence, studying the connection between charisma and the emotional sphere of a leader, studying the development of charismatic leadership taking into account cultural, professional and organizational context.

MATCHING DYADIC RESEARCH QUESTIONS WITH DYADIC ANALYTIC MODELS

Abstract Examining shared and common experiences between dyads affords opportunities to answer interesting research questions using dyadic data. Emerging dyadic methodology has expanded the types of research questions researchers can ask and answer. This session aims to equip researchers with knowledge and resources for grant writing, when planning new data collection projects, or when conducting secondary data analyses. Reviewing both cross-sectional and longitudinal methods, we will walk attendees through several types of research questions and match them with appropriate dyadic analytic strategies. These include the Actor-Partner Interdependence Model (APIM), the Common Fate Model, the Dyadic Growth Curve Model (and ALT Model), the Common Fate Growth Curve Model, the Random Intercept Cross-lagged Model, as well as various extensions. We will address accounting for non-independence in dyadic models, along with how to explore substantive dyadic processes. We will review ways that different approaches conceptualize, assess, and examine within and between dyad comparisons. We will also consider ways to address self and other reports of the same construct, such as health congruence/concordance or discordance/difference, as well as perceptions of accuracy or bias, enhancement, and idealization between dyads. Attendees will learn of resources available to learn more about the methods addressed in this session.

The association between personality, relationship satisfaction, and psychopathology in a three-wave, longitudinal study.

The aim of this work was to better understand the role of personality as it relates to psychopathology, with satisfaction as a mediating variable. Personality is an important determinant of many life outcomes including relationship satisfaction and psychopathology. Previous work has demonstrated that broad domains of normal personality have low-to-moderate associations with various forms of psychopathology. Research has primarily focused on mechanisms that might explain how common personality traits put one at risk for common forms of psychopathology; this work builds upon existing work in examining relationship satisfaction as one possible mechanism. No study to date has examined whether relationship satisfaction mediates the connection between personality and psychopathology. We utilized multilevel modeling in a longitudinal sample of 100 newlywed couples to test the hypothesis that major domains of personality (positive temperament, negative temperament, disinhibition) have a significant effect on relationship satisfaction which, in turn, is significantly associated with internalizing and externalizing forms of psychopathology. We found no evidence for the mediating role of relationship satisfaction; however, in exploratory analyses, we did find evidence for both between-person and within-person effects of personality on psychopathology. This study confirms the role of personality as an important factor in consideration of dyadic processes, though not entirely deterministic for downstream functioning. Thus, separate factors in addition to personality may be worth examining in consideration of how low relationship satisfaction may be associated with psychopathology.

Institutional interactions and racial inequality in policing: How everyday encounters bridge individuals, organizations, and institutions

AbstractRacial disparities in policing are profound and accompanied by equally persistent gaps in trust. Analyses of these and other racial inequities are often bifurcated between institutional and individual levels of analysis. Here, I describe how everyday contacts between the public and doctors, teachers, or police officers—institutional interactions—can bridge these levels. Organizations direct and coordinate these agents' individual discretion; at the same time, individual agents relate to the public in ways institutions themselves cannot. The dual nature of these encounters links individual and dyadic processes to organizational and institutional ones. Using police stops as a paradigmatic example, I illustrate how institutional interactions contribute to racial gaps in police‐community trust, how they can be used as a platform for changing the relationship between law enforcement and the public, and how they can inform research on racial inequality in a range of institutional contexts, including health and education.

Clinical Manifestations.

As the disease progresses, people with dementia (PWDs) gradually lose their ability to conduct activities of daily living (ADLs) independently and increasingly rely on family caregivers (CGs) for assistance and support. This can lead to CGs experiencing increased burden. These dyadic processes may be manifested by (a) CGs' increased physical proximity to PWDs (reflecting greater needs for CGs to monitor PWD's needs and safety, and (b) CGs' increased movement (reflecting greater needs to assist PWDs with ADLs and taking on additional household responsibilities). Working with an industry partner, we developed a wearable watch that measured: (a) physical proximity between PWDs and CGs; and (b) movement of CGs and PWDs in their homes. In the current study, we examined how these wearable-based measures correlated with standard measures of PWD's ADLs and CG's burden. PWDs and CGs each wore a low-energy Bluetooth watch that provided long-battery-life (up to four months). The watches broadcasted information about proximity to three Bluetooth receivers placed in different rooms (which helped us determine the proximity between the PWDs and CGs) and used a three-axis accelerometer to determine movement on a second-by-second basis. In a nationwide US sample, 27 PWDs diagnosed with dementia or mild cognitive impairment and their co-residing familial CGs wore these watches over a six-month period. CGs also completed online questionnaires assessing PWDs' ADLs (Lawton Instrumental Activities of Daily Living) and their own perceived burden from caregiving (Zarit Burden Interview) at the beginning and the end of the study. Over the six-month period, greater increases in PWD-CG proximity were associated with greater increases in CG's burden (r = 0.57, p = .009). In addition, greater increases in CGs' (but not PWDs') movement were associated with greater decreases in PWD's ADLs (r = -0.55, p = .005). These wearable devices show promise of providing scalable remote measures that are associated with ADLs in PWDs and burden in CGs. Findings also underscore the dyadic nature of dementia caregiving, with assessments of CGs useful for understanding changes in ADLs in PWDs, and assessments of PWDs useful for understanding changes in burden in CGs.
