Reversing Arrows in Mediation Models Does Not Distinguish Plausible Models

Reversing arrows in the classic tri-variate X-M-Y mediation models as a test to check whether one mediation model is superior to another is inadmissible. Presenting evidence that one tri-variate mediation model yields a significant indirect effect, whereas one with some reversed arrows does not, is not proof or even evidence that one model should be preferred. In fact, the significance of the indirect or any other effect can never be used to infer whether one model should be preferred over another, if the models are in the same so-called equivalence class. The practice of running several mediation models with reversed arrows to decide which model to prefer should be abandoned. The only way to choose among equivalent models is through assumptions that are either fulfilled by design features or invoked based on theory. Similar arguments about reversing arrows in mediation models have been made before, but this current work is the first to derive this result analytically for the complete (Markovian) equivalence class of the tri-variate mediation model.     

Neuroticism and Marital Satisfaction During the Early Years of Chinese Marriage: The Mediating Roles of Marital Attribution and Aggression

On the basis of three annual waves of data obtained from 268 Chinese couples, we tested an actor–partner interdependence mediation model in which spouses’ neuroticism was linked to their own and partners’ marital satisfaction through both intrapersonal processes (i.e., marital attribution) and interpersonal processes (i.e., marital aggression). Considering intra‐ and interpersonal processes simultaneously, four indirect, mediating pathways were identified: Time 1 Wives’ Neuroticism → Time 2 Wives’ Attribution or Aggression, while controlling for Time 1 Wives’ Attribution or Aggression → Time 3 Wives’ or Husbands’ Marital Satisfaction, while controlling for Time 1 Wives’ or Husbands’ Marital Satisfaction. This study not only adds to a limited body of research examining why neuroticism is associated with conjugal well‐being, but also extends prior research by focusing on Chinese couples and utilizing a longitudinal, dyadic mediation model. Such findings have important practical implications. Couples involving neurotic partners may benefit from interventions based on cognitive‐behavioral approaches. When working with couples challenged by neuroticism, practitioners need to help them address dysfunctional interactive patterns as well as distorted cognitive styles.     

Childhood emotional abuse and attachment processes in the dyadic adjustment of dating couples

In an effort to improve understanding of the mechanisms that link early maltreatment to later outcomes, this study investigated the mediation effects of adult attachment processes on the association between childhood emotional abuse and later romantic relationships among heterosexual couples. College students and their dating partners (N = 310; 155 couples) completed the Childhood Trauma Questionnaire, Experiences in Close Relationship Scale, and Dyadic Adjustment Scale. Using the Actor–Partner Interdependence Model (Kenny, Kashy, & Cook, 2006), multilevel modeling results indicated that memories of childhood emotional abuse reported by both students and their partners were significantly associated with attachment strategies, as well as romantic relationship quality. Findings supported hypothesized mediation effects of attachment anxiety and avoidance.     

Couple Communication as a Mediator Between Work–Family Conflict and Marital Satisfaction

Using a sample of married individuals employed full-time (N = 1,117), this study examined the mediating effects of constructive and destructive communication between partners on the relationship between work–family conflict and marital satisfaction. Results from structural equation modeling revealed that work–family conflict was significantly and negatively related to marital satisfaction. This relationship became insignificant when constructive and destructive communication were added to the model, evidence for full mediation. This was confirmed with Sobel’s test for mediation. Results suggest that teaching communcation skills may be a potent point of intervention for couples who experience high levels of work–family conflict.     

The Role of Dyadic Discord in Outcomes in Acute Phase Cognitive Therapy for Adults With Recurrent Major Depressive Disorder

Major depressive disorder (MDD) and relationship discord between cohabiting partners frequently co-occur, with bidirectional effects established. As relationship quality influences understanding and treatment of MDD, the current analyses clarified the relations of pretreatment dyadic discord with outcomes during and at the end of acute phase cognitive therapy (CT) for adults with recurrent MDD. Married or cohabiting patients (n = 219) completed the Dyadic Adjustment Scale (DYS) before and after a 16–20 session, 12–14 week CT protocol. Lower levels of dyadic adjustment indicated higher levels of dyadic discord. Response to CT was defined as the absence of a major depressive episode and ≤ 12 on the 17-item Hamilton Rating Scale for Depression. Pretreatment dyadic discord, whether defined as a continuous or categorical variable (using DYS cutoff score of 97), was not associated with treatment completion or response but was positively associated with levels of depressive symptoms at the end of acute phase CT. Furthermore, CT was associated with declines in dyadic discord, with 23.3% of initially discordant couples moving to nondiscordant status at the end of CT. Depressive symptoms did not significantly mediate changes in dyadic discord. Finally, pre- (but not mid-) treatment dyadic discord was associated with subsequent changes in depressive symptoms, suggesting limited mediation. These findings replicate prior research indicating that individual CT is associated with reductions in depressive symptoms and dyadic discord while clarifying that lower pre-treatment dyadic discord may predict initial improvement in depressive symptoms.     

Mediation Analysis in Social Psychology: Current Practices and New Recommendations

A key aim of social psychology is to understand the psychological processes through which independent variables affect dependent variables in the social domain. This objective has given rise to statistical methods for mediation analysis. In mediation analysis, the significance of the relationship between the independent and dependent variables has been integral in theory testing, being used as a basis to determine (1) whether to proceed with analyses of mediation and (2) whether one or several proposed mediator(s) fully or partially accounts for an effect. Synthesizing past research and offering new arguments, we suggest that the collective evidence raises considerable concern that the focus on the significance between the independent and dependent variables, both before and after mediation tests, is unjustified and can impair theory development and testing. To expand theory involving social psychological processes, we argue that attention in mediation analysis should be shifted towards assessing the magnitude and significance of indirect effects.     

Predictors of Engagement in Family Mediation and Outcomes for Families that Fail to Engage

An important limitation to the effectiveness of family mediation in assisting separated parents is parents failing to engage in the mediation process. In 524 parents who presented to a telephone‐based mediation service, 113 (22%) initiating parents withdrew from mediation before the other parent was invited to participate, 241 (46%) initiating parents had respondent parents who declined to participate in mediation, and 170 cases (33%) completed mediation. We tested whether socio‐demographic variables, psychological distress, coparental acrimony, parenting problems, or children's behavioral difficulties predicted mediation engagement. High interparental acrimony predicted failure to engage in mediation, but none of the other variables predicted mediation engagement. We followed a sample of 131 families that did not mediate and found they showed elevated psychological distress, acrimony, parenting problems and child adjustment difficulties, which remained unchanged 6 months later. Further research is needed to explore strategies to enhance respondent parent engagement with mediation, and to address the negative outcomes for those separated families not proceeding with mediation.     

Reflective Sociocultural Psychology: Lost and Found in Collaboration with Funding Agencies and ICT Experts

This paper deals with emerging kinds of collaboration between researchers, funding agencies and ICT (Information and Communications Technology) experts. The goal of this paper is to analyze the challenges and opportunities for researchers presented by such collaborations. The analysis is based on a sociocultural approach, and leads to the following conclusions: (a) the main challenges to collaboration arise from the fact that partners’ communities have different goals and use different sets of mediation tools, (b) there are different ways for researchers to cope with more powerful partners such as major funding agencies (refusing collaboration, pseudo collaboration, asymmetric collaboration, and real partnership), (c) appropriation of mediation tools developed by partners could be useful for researchers, (d) collaboration with partners could be a source of new theoretically interesting phenomenon, and (e) communication with partners who are not familiar with our routine discourses might help us to improve our own understanding.

Threat and social-choice: when eye size matters

The Environmental Security Hypothesis (T. F. Pettijohn II & A. Tesser, 1999) indicates that as environmental threat increases, the desirability of persons with neotenous features should decrease. In 2 experiments (Ns = 96, 80), the authors tested this hypothesis and a mediation account that was based on the attributions made about neotenous and mature-featured others. In each experiment, the authors manipulated threat and gave participants the choice of a neotenous (increased eye-size) or mature (decreased eye-size) female partner. The authors tested mediation in Study 1 by experimentally uncoupling attributions from facial features and in Study 2 by manipulating the participant's dependence on his or her partner. Both studies provided evidence for the Environmental Security Hypothesis: Preference for partners with neotenous facial features decreased under high threat. Support for the role of attributions as mediators was mixed. An alternative interpretation of the results indicates the possibility that responses to facial features may depend on nonconscious processing.     

THE ROLE OF INITIAL CONVERSATIONS IN DETERMINING ATTRACTION TO SIMILAR AND DISSIMILAR STRANGERS

The present study focused on identifying the independent and conjoint influence of attitude similarity and initial interaction on interpersonal attraction to relative strangers. Participants were informed they would be working on a project with either an attitudinally similar or an attitudinally dissimilar stranger. Half of the participants next engaged in an initial interaction with their partner and the other half did not. All participants then filled out a scale that included a measure of interpersonal attraction. Results indicated that the conjoint, nonadditive effects of attitude similarity and initial interaction overrode the significant main effects of these variables. Although attitudinally similar noninteractants were more attracted to their partners than dissimilar noninteractants, no differences in attraction were observed among similar and dissimilar interactants. Dissimilar interactants were more attracted to their partners than dissimilar noninteractants, but no differences in attraction were observed between similar interactanls and noninteractants.     

Attachment experience and cortisol recovery from romantic conflict among young Chinese couples: A dyadic analysis

Using a sample of young adults, the present study investigated how the participants' attachment to romantic partners was related to that with their parents and peers and how this specific attachment experience was associated with their physiological stress response. We examined 121 pairs of young Chinese (N = 242) heterosexual couples (men's age: 22.26 ± 2.40; women's age: 21.62 ± 2.22) and their attachment to parents, peers, and romantic partners as well as their cortisol recovery from romantic conflict. Robust actor–partner interdependence mediation models showed that women's insecure parental and peer attachment was associated with blunted cortisol recovery from romantic stress through their fearful attachment with romantic partners, whereas men's insecure parental and peer attachment was associated with their partners' adaptive cortisol recovery from romantic stress through their fearful romantic attachment. These findings suggested that women's hypothalamic–pituitary–adrenal-axis functioning seemed to be more strongly associated with their own and their partners' attachment relationships compared to men.     

Condom use in steady and casual sexual relationships: Planning, preparation and willingness to take risks among adolescents

Condom use within steady and casual sexual relationships was examined among 14-16 year old Dutch adolescents from secondary school (N?=?140). It was hypothesised that among adolescents sex and subsequently condom use with casual sex partners is less likely to be considered in advance, more context-dependent and less habitual; whereas the opposite is true for steady relationships. Therefore, preparatory behaviours (buying and carrying condoms and communicating about condom use) were expected to mediate the intention-behaviour relation in the context of steady relationships, but not in the context of casual sex. Results confirmed that condom use with steady sex partners was explained by preparatory behaviours, habits, and to some extent, behavioural willingness, and that preparatory behaviours mediated the intention-behaviour relationship. Condom use with casual sex partners was predicted by risk willingness and intentions, without any mediation by preparatory behaviours. The results indicate that it is essential to increase awareness among adolescents that unexpected sexual situations may occur and to train them to take preparatory actions.

The attachment system in fledgling relationships: an activating role for attachment anxiety

Is it sensible to study attachment dynamics between potential romantic partners before they share a full-fledged attachment bond? The present data indicate that such an approach may reveal novel insights about initial attraction processes. Four studies suggest that the state-like experience of attachment anxiety has functional implications within fledgling (i.e., desired or undeveloped) romantic relationships, well before the formation of an attachment bond. Studies 1 and 3 reveal that attachment anxiety directed toward a particular romantic interest is elevated before (in comparison with after) participants report being in an established relationship. Studies 2 and 3 demonstrate that such partner-specific attachment anxiety predicts attachment-relevant outcomes in fledgling relationships, including proximity seeking, safe haven, secure base, passionate love, and other approach behaviors. These associations were reliable above and beyond (and were typically as strong as or stronger than) the effect of sexual desire. Finally, Study 4 presents evidence that partner-specific attachment anxiety may cause several of these attachment-relevant outcomes. Attachment anxiety seems to be a normative experience and may signal the activation of the attachment system during the earliest stages of romantic relationships.     

类别变量的中介效应分析

在心理学和其他社科研究领域,研究者能熟练地进行连续变量的中介效应分析,但面对自变量、中介变量或(和)因变量为类别变量的中介效应分析,研究者往往束手无策。在阐述类别自变量中介分析方法的基础上,我们建议使用整体和相对中介相结合的类别自变量中介分析方法,并给出了分析流程。以二分因变量为例,讨论了中介变量或(和)因变量为类别变量的中介分析方法的发展过程(即尺度统一的过程),建议通过检验Za×Zb的显著性来判断中介效应的显著性。用二个实际例子演示如何进行类别变量的中介效应分析。最后展望了类别变量的中介效应分析研究的拓展方向。     

To Know You is (Not) to Want You: Mediators Between Sociosexual Orientation and Romantic Commitment

Past studies have indicated that individuals with an unrestricted sociosexual orientation (SO; ‘unrestricted’ reflects comfort with sex outside the confines of a committed relationship) emphasize attractiveness and desirability when pursuing romantic partners. Additionally, SO is related to decreased commitment, and ultimately increased infidelity, in a current romantic relationship. Thus, the current study investigates potential mediators between sociosexual orientation (SO) and romantic commitment. Perceptions of a romantic partner’s characteristics such as physical attractiveness, various personality traits, and perceived similarities were examined as mediators. The findings indicate perceived social skills, intellect, and perceived similarities with the partner were all significant mediators between SO and commitment. Additionally, physical attractiveness was a marginally significant mediator. The final mediation model suggests that individuals with unrestricted SOs may have lower commit in their current relationships because participants with an unrestricted SO, compared to participants with a restricted SO, rated their partners as having fewer social skills, less intellect, and also fewer similarities between themselves and their partners.     

Conditional estimation of exponential random graph models from snowball sampling designs

A complete survey of a network in a large population may be prohibitively difficult and costly. So it is important to estimate models for networks using data from various network sampling designs, such as link-tracing designs. We focus here on snowball sampling designs, designs in which the members of an initial sample of network members are asked to nominate their network partners, their network partners are then traced and asked to nominate their network partners, and so on. We assume an exponential random graph model (ERGM) of a particular parametric form and outline a conditional maximum likelihood estimation procedure for obtaining estimates of ERGM parameters. This procedure is intended to complement the likelihood approach developed by  Handcock and Gile (2010) by providing a practical means of estimation when the size of the complete network is unknown and/or the complete network is very large. We report the outcome of a simulation study with a known model designed to assess the impact of initial sample size, population size, and number of sampling waves on properties of the estimates. We conclude with a discussion of the potential applications and further developments of the approach.     

Symptom-system fit in couples: emotion regulation when one or both partners smoke

In a laboratory smoking experiment, 25 couples in which 1 or both partners continued to smoke despite 1 of them having heart or lung disease discussed a health-related disagreement before and during a period of smoking. Immediately afterward, the partners used independent joysticks to recall their continuous emotional experience during the interaction while watching themselves on video. Participants in dual-smoker couples reported increased positive emotion contingent upon lighting up, whereas those in single-smoker couples reported the opposite. The results highlight the role of smoking in close relationships, particularly in regulating emotional closeness when both partners smoke. Attention to this fit between symptom and system may be useful in helping couples achieve stable cessation.     

A Comparison of the Effectiveness of Substantive and Contextual Mediation Tactics1

The effectiveness of three mediation tactics was compared in two laboratory studies. It was hypothesized that a content mediation procedure which involved identifying the priorities of both parties and suggesting a trade-off of low for high priority issues would be most effective in helping to resolve the dispute, followed by an issue identification mediation procedure in which priorities were identified but no suggestions were made. A positive framing mediation procedure in which the benefits of a negotiated settlement were emphasized was expected to be somewhat less effective. In Study 1, 64 students played the role of company negotiator and interacted with a programmed citizen group negotiator. All three mediation tactics produced more satisfactory outcomes (higher joint payoffs) than did a no-mediation condition. In Study 2, 46 pairs of students negotiated with one another and received content mediation, issue identification mediation, positive framing mediation, or no mediation. Negotiators receiving content mediation achieved more satisfactory outcomes (higher joint profits) than did negotiators in the other 3 conditions. Results are discussed in terms of a contingency model of mediation effectiveness.     

Positive psychology in context: Effects of expressing gratitude in ongoing relationships depend on perceptions of enactor responsiveness

Recent correlational evidence implicates gratitude in personal and relational growth, for both members of ongoing relationships. From these observations, it would be tempting to prescribe interpersonal gratitude exercises to improve relationships. In this experiment, couples were randomly assigned to express gratitude over a month, or to a relationally active control condition. Results showed modest effects of condition on personal and relational well-being. However, those whose partners were perceived as being particularly responsive when expressing gratitude at the initial lab session showed greater well-being across a range of outcomes, whereas this was not so for people in the control condition. Notably, evidence raises concerns about the effectiveness of artificial injections of gratitude when the partner is perceived to be low in responsiveness. Given the importance of close relationships, this work highlights the need for more theory-driven basic research tested in context before assuming what appears to work naturally will also work artificially.
