Moderation in the actor–partner interdependence model

Potential moderators of effects in the actor–partner interdependence model (APIM) include variables that vary within dyads, between dyads, or both between and within dyads (i.e., mixed moderators). Another factor in the moderation of the APIM is whether dyads are indistinguishable (e.g., same‐sex friendship pairs) or distinguishable (e.g., heterosexual couples). For each possibility, what are the potential moderator effects (up to 8), how they might be estimated and tested, and how they can be interpreted are discussed. Submodels are also presented, based on patterns of moderation of the actor and partner effects, which are statistically simpler, more conceptually meaningful, and more powerful in testing moderator effects. Example analyses illustrate the recommended steps involved in an APIM moderation analysis.     

Extending the actor–partner interdependence model for binary outcomes: A multilevel logistic approach

Relationship researchers face many challenges when samples consist of dyads. The actor–partner interdependence model provides a framework for the analysis of dyadic data (D. A. Kashy & D. A. Kenny, 2000). Binary variables like discrete health diagnoses present additional challenges that are not easily handled using existing models. The analysis was demonstrated using SAS PROC GLIMMIX and HLM6. An example is presented where couple's personality traits are used to predict discrete health outcomes. A series of Monte Carlo simulations were performed to compare PROC GLIMMIX to HLM. GLIMMIX performed acceptably compared to HLM for small dyad‐level sample sizes (100 or fewer), but HLM clearly outperformed in larger samples. Both had problems estimating the variance of the random intercept and its standard error.     

Marital commitment,communication and marital satisfaction: An analysis based on actor–partner interdependence model

Marital commitment and satisfaction are known to be closely related, but only limited research has examined the asymmetric interaction patterns between spouses. In this paper, the authors study 400 Chinese couples and find that communication mediates the relationship between marital commitment and marital satisfaction. Using the actor–partner interdependence model, they find that wives and husbands show asymmetric associations for marital commitment, communication and satisfaction. Specifically, compared with husbands, wives are more attuned to the path from marital commitment to marital satisfaction via communication. Implications and limitations are discussed.     

Testing crossover effects in an actor–partner interdependence model among Chinese dual‐earner couples

The purpose of the present study is to examine the crossover effects from one partner's work–family interface (work–family conflict [WFC] and work–family enrichment [WFE]) to the other partner's four outcomes (psychological strain, life satisfaction, marital satisfaction and job satisfaction) in a sample of Chinese dual‐earner couples. Married couples (N = 361) completed a battery of questionnaires, including the work–family interface scale, the psychological strain scale, the life, marital, as well as job satisfaction scale. Results from the actor–partner interdependence model (APIM) analyses showed that wives' WFE was negatively associated with husbands' psychological strain, and positively associated with husbands' life, marital and job satisfaction. Furthermore, husbands' WFC was negatively related to wives' marital satisfaction, whereas husbands' WFE was positively related to wives' marital satisfaction. Theoretical and practical implications were discussed, and future research directions were provided.     

The actor–partner interdependence model for categorical dyadic data: A user‐friendly guide to GEE

The actor–partner interdependence model (APIM) has been widely used for the analysis of pairs of individuals who interact with each other. The goal of this article is to detail in a nontechnical way how the APIM for binary or count outcomes can be implemented and how actor and partner effects can be estimated using generalized estimating equations (GEE) methodology. Both SPSS‐ and SAS‐syntax needed to estimate the model and the interpretation of the output are illustrated using data from a study exploring the effect of satisfaction with the relationship before the breakup on unwanted pursuit behavior after the breakup in formerly married partners. The use of this GEE method will allow researchers to test a wide array of research hypotheses.     

Giving dyadic data analysis away: A user‐friendly app for actor–partner interdependence models

The actor–partner interdependence model (APIM) is widely used for analyzing dyadic data. Although dyadic research has become immensely popular, its statistical complexity can be a barrier. To remedy this, a free user‐friendly web application, called APIM_SEM, has been developed. This app automatically performs the statistical analyses (i.e., structural equation modeling) of both simple and complex APIMs. It allows the researcher to analyze distinguishable or indistinguishable dyads, to examine dyadic patterns, to estimate actor and partner effects of one or two predictors, and to control for covariates. Results are provided in software and text format, complemented by summary tables and figures. As an illustration, the effect of perception of the partner on satisfaction is assessed by fitting APIMs with varying complexity.     

Dyadic effects of marital satisfaction on coparenting in Chinese families: Based on the actor‐partner interdependence model

Based on the actor‐partner interdependence model, this study explored the spillover and crossover effects of marital satisfaction on coparenting in Chinese nuclear and extended families. Spillover and crossover effects refer to the transfer of experiences, affects or behaviors, focusing on the intra‐personal and inter‐personal transfer of a marital subsystem to a coparenting subsystem. The participants comprised 279 couples with children ranging in age from 3 to 7 years old. The marital satisfaction and extent of coparenting of both the fathers and the mothers was tested to examine the dyadic interaction. Structural equation modeling results revealed significant intra‐personal and inter‐personal correlations between marital satisfaction and coparenting, indicating spillover and crossover effects in nuclear and extended families, and there were no differences between the two family structures. The results indicated that fathers' marital satisfaction influenced both fathers' and mothers' coparenting practices.     

Ask and you might receive: The actor–partner interdependence model approach to estimating cultural and gender variations in social support

As an essential part of close relationships, social support is a dynamic interactive process. This paper aims to simultaneously investigate social support‐seeking and provision behaviours using the Actor–Partner Interdependence Model (APIM). Ninety‐two friendship dyads participated in this study. Supportive versus negative friendship qualities were used to predict different support‐seeking and support‐provision behaviours during an experimental task. Cultural and gender variations were also examined. Results showed that self‐reported friendship qualities influence support‐seeking and provision behaviours intrapersonally and interpersonally. Female participants were more likely to provide emotion‐focused support than were male participants. After accounting for friendship qualities in the dyads, there was no evidence of cultural group differences on support‐seeking or provision behaviours among same‐sex friends. These results demonstrate the conceptual and empirical advantages of using APIM to unpack cultural and gender variations in social support processes.     

Social interdependence in close relationships: The actor–partner‐interdependence–investment model (API‐IM)

This article introduces the actor–partner‐interdependence–investment model (API‐IM) that was developed to add a dyadic perspective to Rusbult's investment model. The API‐IM is based on interdependence theoretical assumptions and the actor–partner interdependence model. Two studies were conducted to investigate the reliability of the API‐IM. Relationship satisfaction, investment size, quality of alternatives, and relationship commitment were assessed at both partners of 77 (Study 1) and 162 (Study 2) married and unmarried heterosexual couples. Path analyses that applied a structural equation modeling framework revealed a dyadic model that significantly predicts women's and men's commitment by actor effects of satisfaction, investments, and alternatives, and partner effects of satisfaction. Actor and partner effects of satisfaction were significantly moderated by relationship duration and marital status. Marital status also significantly moderated the actor effect of alternatives. The API‐IM supports the concept of social interdependence in close relationships, and it is discussed as a sound dyadic extension of the investment model.

Computer-based dissemination: a randomized clinical trial of ePREP using the actor partner interdependence model

The most pressing challenge facing our field is to close the gap between the need for evidence based treatment and our ability to effectively provide it. We illustrate how an empirically supported treatment can be adapted for computerized administration to maximize the likelihood of widespread dissemination. This randomized clinical trial shows how computer-based treatments can be effectively used to increase flexibility in reaching target populations. Using the actor partner interdependence model, we found that, compared to those who received a placebo intervention, ePREP participants demonstrated better mental health and relationship functioning at a six-week follow up. Those who engaged more fully in the intervention and mastered the communication techniques generally experienced superior outcomes. Implications of and recommendations for computer-based dissemination are discussed.     

Perspective‐taking induction mitigates the effect of partner attachment avoidance on self–partner overlap

Adult attachment avoidance has long been associated with relationship turmoil and dissatisfaction, and some research has highlighted the clinical potential of perspective‐taking (PT) training for ameliorating attachment avoidance‐related relationship difficulties. Prior research also suggests that prosocial sequelae of PT are mediated by increased self–other overlap. This study examined how a brief PT induction preceding an unresolved conflict discussion interacted with individual differences in attachment avoidance to influence postconflict ratings of self–partner overlap. The authors found that the PT induction buffered the effect of partner—but not one's own—avoidance on self–partner overlap. Main effects of PT condition and both actor and partner avoidance were also detected, and results remained unchanged when controlling for indirect intracouple overlap and relevant individual and couple characteristics.     

Reflections on the work of Hanna Segal (1918–2011),

This paper is based on a talk given at the conference to celebrate the Work of Hanna Segal and attempts to summarise her contribution to psychoanalysis. I suggest that in addition to being the important presenter of the work of Melanie Klein, she made major contributions to our understanding of many analytic ideas, for example, symbol formation, the usefulness of the concept of the death instinct and the relation between phantasy and reality. She was a pioneer in the analytic treatment of psychosis and sh wrote important papers on literature and aesthetics. She was a great teacher and emphasised the central role played by the analytic setting in representing the attitude of the analyst.     

Culture,social class,and independence–interdependence: The case of Chinese adolescents

Social class demarcates sociocultural environments differing in the relative abundance and scarcity of resources, which in turn differentially afford independent and interdependent psychological processes. The relationships between social class and psychological processes are well documented in Western populations but less so elsewhere. Examining such a relationship is particularly important in China, with its unique historical and sociocultural issues surrounding social class. This research examined the relationship between social class and independence–interdependence among Chinese adolescents (N = 1184). Findings were consistent across a diverse array of psychological processes implicated by independence–interdependence: Participants with well‐educated parents experienced more socially disengaging emotions and a higher level of self‐esteem, and were more inclined toward dispositional attribution and focused attention, compared to participants with less well‐educated parents. These findings highlight the cross‐cultural commonality in the relationship between social class and independence–interdependence.     

Modeling homophily over time with an actor-partner interdependence model

Selection and socialization have been implicated in friendship homophily, but the relative contributions of each are difficult to measure simultaneously because of the nonindependent nature of the data. To address this problem, the authors applied a multiple-groups longitudinal actor-partner interdependence model (D. A. Kashy & D. A. Kenny, 2000) for distinguishable dyads to 3 consecutive years of intoxication frequency data from a large community-based sample of Swedish youth. Participants, ranging from 12 to 18 years old (M = 14.35, SD = 1.56) at the start of the study, included 902 adolescents (426 girls and 476 boys) with at least one reciprocated friend during at least one time point and 212 adolescents (84 girls and 128 boys) without reciprocated friends at any time. Similarity estimates indicated strong effects for selection and socialization in friends' intoxication frequency. Over time, younger members of these dyads had less stable patterns of intoxication than older members, largely because younger partners changed their drinking behavior to resemble that of older partners.     

Rape and Communicative Agency: Reflections in the Lake at L–

Freud's case study of “Dora” ignores indications that her symptoms might have resulted from a fear of rape. Drawing on feminist adaptations of Lacan, this paper suggests that fear of rape may serve as a horizon for women's ability to perceive themselves as efficacious speakers. Freud's failure to recognize this fear may reflect men's unwillingness to acknowledge their own role in rape as well as anxiety over the possibility of losing his own credibility.
