Methodological issues in event-related brain potential research

Event-related brain potential (ERP) measures have become increasingly popular in experimental psychology and are often employed by researchers who are not formally trained in electrophysiology. A proper application of these measures requires knowledge about the methodological principles and practical issues that are relevant to ERP measurement, analysis, and interpretation. A brief introductory survey of different aspects of ERP methodology (recording, data processing and signal extraction, statistical analysis and interpretation of ERP effects) is presented, and the contributions collected in this special issue on ERP methodology are introduced.     

Modeling Concordance Correlation Coefficient for Longitudinal Study Data

Measures of agreement are used in a wide range of behavioral, biomedical, psychosocial, and health-care related research to assess reliability of diagnostic test, psychometric properties of instrument, fidelity of psychosocial intervention, and accuracy of proxy outcome. The concordance correlation coefficient (CCC) is a popular measure of agreement for continuous outcomes. In modern-day applications, data are often clustered, making inference difficult to perform using existing methods. In addition, as longitudinal study designs become increasingly popular, missing data have become a serious issue, and the lack of methods to systematically address this problem has hampered the progress of research in the aforementioned fields. In this paper, we develop a novel approach to tackle the complexities involved in addressing missing data and other related issues for performing CCC analysis within a longitudinal data setting. The approach is illustrated with both real and simulated data.

Increasing husbands' involvement in domestic labor: Issues for therapists

As a result of the dramatic increase in women's participation in the work force, more relationship therapists are seeing couples who are dissatisfied with how domestic labor is divided in their homes. Although, this issue may seem therapeutically straightforward, there are many aspects which make its renegotiation surprisingly problematic and complex. This article is an effort to delineate some of these issues such as engaging men in therapy, exploring emotional issues connected with housework, and the mechanism of gatekeeping. Also included is a therapeutic framework for addressing client concerns about domestic responsibilities.     

Editorial synthesis for 2 in 2023 a collaboration between IARR's two journals: Recognizing the need for greater inclusivity in relationship science

The idea for this special issue came from the current Editors of the Journal for Social and Personal Relationships and Personal Relationships, who wanted to forge a collaboration between the International Association for Relationship Research's two journals. The timing of such collaboration came at a time when issues surrounding diversity, equity, and inclusion were being brought to light in science, broadly defined. Stemming from such discussions, for this special issue, we asked 10 sets of authors to apply an intersectional lens—grounded in Crenshaw's (1989, 1991) definition of intersectionality and drawing from questions posed by Cole (2009)—in their systematic review of literature from the past 20 years (1992–2022) and to answer these three questions: (1) from whose vantage point is the research being conducted, (2) what types of questions are valued, and (3) who is included in the research vs. who is being left out/whose voices are missing. Reviews for the special issue include these topics: (a) affectionate communication, health, and relationships, (b) romantic relationship maintenance behaviors, (c) relationship maintenance among military couples, (d) relational sacrifices, (e) LGBTQ-inclusive research, (f) stress, support, and coping for romantic couples, (g) daily stress and romantic relationship quality, (h) infidelity, (i) relationship dissolution, and (j) the longitudinal study of romantic close relationships. Across the reviews, authors noted many of the same patterns; most studies included samples from the United States, wherein participants identified as White, heterosexual, and/or female; however, military samples were dominated by men. The methods employed were largely quantitative, cross-sectional, and/or with data coming from surveys. Observations during the review process included the role of positionality as well as greater knowledge gained about the critical framework of intersectionality, specifically acknowledging that elements of diversity in sampling methods are not an application of intersectionality; rather, intersectionality places central focus on (a) how multiply marginalized social identities have been historically oppressed and (b) how systems of power, oppression, and privilege construct, reproduce, and sustain those multiply marginalized social identities. Recommendations for future relationship science are presented, specifically in how our fields can benefit from learning from the lens of intersectionality.     

Healthy marriage initiatives: on the need for empiricism in policy implementation

The association between marriage and well-being has led to policies that promote marital interventions and discourage divorce. These include federal initiatives specifically targeting poor couples and couples of color. While there are many prospective studies on marriage that have informed some couple interventions, the studies that are included in this literature sampled predominantly White and middle-class couples. By comparison, far less is known about the longitudinal predictors of relationship satisfaction and status for poor couples and couples of color. Therefore, it is unsurprising that preliminary data on applying current interventions to the couples targeted by these federal initiatives have been disappointing. In this article, I detail three concerns with these initiatives, propose a course of psychological research to address deficits in what is known about poor couples and couples of color, and make specific recommendations to enhance the effectiveness of these initiatives.     

Practical advice for conducting ethical online experiments and questionnaires for United States psychologists

It is increasingly easy and, therefore, increasingly common to conduct experiments and questionnaire studies in online environments. However, the online environment is not a data collection medium that is familiar to many researchers or to many research methods instructors. Because of this, researchers have received little information about how to address ethical issues when conducting online research. Researchers need practical suggestions on how to translate federal and professional ethics codes into this new data collection medium. This article assists United States psychologists in designing online studies that meet accepted standards for informed consent, deception, debriefing, the right to withdraw, security of test materials, copyright of participants’ materials, confidentiality and anonymity, and avoiding harm.     

Gendered Power in Cultural Contexts: Part I. Immigrant Couples

Immigration is a world-wide phenomenon and practitioners are increasingly called on to work with issues related to it. The authors examine the experience of couples who are immigrants to the United States in regard to gender and power issues. Although the study limited participation to one religious group in order to hold that aspect of culture and gender attitudes constant, the experiences of these couples help to make visible the link between microlevel couple interaction and larger social processes. The results show how the couples manage a delicate balance between the push for gender change and avoiding too much conflict as male power is challenged.     

Handling greedy clergy roles: A dual clergy example

Striking changes have occurred in the number of women who have been ordained as clergy in the Protestant denominations in North America. With these changes has come a concomitant increase in the number of dual clergy couples. These couples are a new variant on the dual career theme. They share some of the same strains which have been identified for dual career couples in general; namely, identity issues, work and role overload, role cycling problems, social network dilemmas and discrepancies between personal and social norms. In addition, particular qualities of the clergy role create problems which these couples must address. One such problem is handling the ambivalent boundary between work and family roles. Two aspects of this issue are the absorptiveness of the role and the embeddedness of both work and family roles. The present paper discusses these boundary issues using data from a study of a population of dual clergy couples in two synods of the Lutheran church in two western Canadian provinces. Strategies for handling these issues are suggested for couples, church leaders and congregational representatives.Thanks are expressed to Les Vaala, Director of Student Life, Camrose Lutheran College, Camrose Alberta who was a cooperating researcher in the study.     

Keeping Academic Field Researchers Safe: Ethical Safeguards

Competent risk management is central to the ethical conduct and profitability of organisations including universities. Recent UK research highlights the risks of physical and psychological harm and emotional distress for researchers and the importance of developing strategies to deal with these issues prior to data being collected. Actual numbers of incidents of researcher harm in Australian universities are unavailable; however anecdotal evidence and Bloor et al.’s (2010) case studies suggest that this is a significant issue. They recommended risk management practices such as training about researcher safety, pre-trip security briefings, established call-back systems, working in pairs, and compulsory de-briefings are recommended. Yet Australian universities do little to protect the safety of field researchers when they collect data in private locations, such as participants’ homes and when dealing with emotionally challenging content. This is at odds with the duty of care requirements on employers in current state based occupational health and safety (OHS) laws where breaches attract considerable penalties. The failure to adequately address the potential safety hazards and manage the risks associated with data collection places Australian universities in a vulnerable position, and possibly at risk of litigation, in their duty to adequately protect researchers. The paper presents a review of the international literature and draws on the UK research. Conceptual modelling is provided to illustrate the risk to universities if researchers are harmed in the field. Finally, the paper concludes with a call for further research to develop robust policy and practice that protects the field researcher.     

What are the Marital Problems of Happy Couples? A Multimethod,Two-Sample Investigation

How couples handle marital conflict may depend on what issues they are facing, as some issues may be more difficult to resolve than others. What is unclear, however, is what issues happy couples face and how these issues may be different for couples depending on their developmental stage. To explore this possibility, the current study used both self-reports and observations drawn from two separate samples of happily married couples—one early in middle adulthood (N = 57 couples; average marital duration = 9 years) and one in older adulthood (N = 64 couples; average marital duration = 42 years). Results indicated that all issues were relatively minor, but early middle-aged couples reported more significant problems than did older couples. As to determining the most salient topic for happy couples, it depended on the spouses’ gender, developmental stage, and how salience was assessed (i.e., highest rated issue vs. most discussed issue). Only moderate links were found between what happy couples said was their most serious concern and what they actually tried to resolve during observations of marital problem-solving, but there were differences in how spouses behaved based on the proportion of their time discussing certain topics. Findings suggest that more attention should be devoted to understanding what marital issues happy couples discuss and why, as doing so may reveal how couples maintain their marital happiness.     

Studying Multivariate Change Using Multilevel Models and Latent Curve Models

In longitudinal research investigators often measure multiple variables at multiple points in time and are interested in investigating individual differences in patterns of change on those variables. In the vast majority of applications, researchers focus on studying change in one variable at a time. In this article we consider methods for studying relations1.1ips between patterns of change on different variables. We show how the multilevel modeling framework, which is often used to study univariate change, can be extended to the multivariate case to yield estimates of covariances of parameters representing aspects of change on different variables. We illustrate this approach using data from a study of physiological response to marital conflict in older married couples, showing a substantial correlation between rate of linear change on different stress-related hormones during conflict. We also consider how similar issues can be studied using extensions of latent curve models to the multivariate case, and we show how such models are related to multivariate multilevel models.     

Integrating Sex and Couples Therapy: A Multifaceted Case History

Traditionally, sexuality has not been a focus in couples therapy training, research, or practice, although it is an important, often complex issue for many couples. This article tells the story of a couple presenting for sex therapy due to their unconsummated marriage, and is told to exemplify how sex therapy and couples therapy can be integrated in order to best meet the needs of couples. As the story unfolds, the multilayered facets of the presenting issue are revealed. The therapy incorporates and weaves together family of origin history, intrapsychic and cognitive issues, relational dynamics, patterns of interaction, and physiological/medical concerns into a postmodern couples therapy with behavioral interventions. This combined approach recognizes the value of each method on its own and their greater usefulness when blended together.     

Analysis and meta-analysis of single-case designs: An introduction

The last 10 years have seen great progress in the analysis and meta-analysis of single-case designs (SCDs). This special issue includes five articles that provide an overview of current work on that topic, including standardized mean difference statistics, multilevel models, Bayesian statistics, and generalized additive models. Each article analyzes a common example across articles and presents syntax or macros for how to do them. These articles are followed by commentaries from single-case design researchers and journal editors. This introduction briefly describes each article and then discusses several issues that must be addressed before we can know what analyses will eventually be best to use in SCD research. These issues include modeling trend, modeling error covariances, computing standardized effect size estimates, assessing statistical power, incorporating more accurate models of outcome distributions, exploring whether Bayesian statistics can improve estimation given the small samples common in SCDs, and the need for annotated syntax and graphical user interfaces that make complex statistics accessible to SCD researchers. The article then discusses reasons why SCD researchers are likely to incorporate statistical analyses into their research more often in the future, including changing expectations and contingencies regarding SCD research from outside SCD communities, changes and diversity within SCD communities, corrections of erroneous beliefs about the relationship between SCD research and statistics, and demonstrations of how statistics can help SCD researchers better meet their goals.     

Multilevel modeling: current and future applications in personality research

Traditional statistical analyses can be compromised when data are collected from groups or multiple observations are collected from individuals. We present an introduction to multilevel models designed to address dependency in data. We review current use of multilevel modeling in 3 personality journals showing use concentrated in the 2 areas of experience sampling and longitudinal growth. Using an empirical example, we illustrate specification and interpretation of the results of series of models as predictor variables are introduced at Levels 1 and 2. Attention is given to possible trends and cycles in longitudinal data and to different forms of centering. We consider issues that may arise in estimation, model comparison, model evaluation, and data evaluation (outliers), highlighting similarities to and differences from standard regression approaches. Finally, we consider newer developments, including 3-level models, cross-classified models, nonstandard (limited) dependent variables, multilevel structural equation modeling, and nonlinear growth. Multilevel approaches both address traditional problems of dependency in data and provide personality researchers with the opportunity to ask new questions of their data.     

Generating Hypotheses After 14 Years of Marital Followup; Or,How Should One Speculate? A Reply to DeKay,Greeno, and Houck*

Gottman and Levenson (2002) for the purpose of post hoc speculation, developed a number of ordinary least squares regressions to model the length of marriage of divorcing couples in a 14-year longitudinal study. We believe that our analyses are appropriate for our purpose. We do not agree with DeKay, Greeno, and Houck (2002) that a duration-model approach would have been more appropriate, and instead argue that the analyses used are more powerful and generate more interesting speculations. When speculating, one makes an important contribution just by being interesting, not necessarily by being right. The purpose of post hoc speculation is to generate discussion, and we are pleased that even at the outset we have accomplished this goal. In this reply to DeKay et al., we argue that the two-process model for earlier versus later divorcing that we propose is both interesting and clinically useful.     

Minimizing Bias and Maximizing the Potential Strengths of Autoethnography as a Narrative Research

Up to the current time, psychology has provided very limited space for qualitative research to contribute to the discipline, even though psychology has a lot to do with subjectivity and intersubjectivity in its work. This article discusses autoethnography, which by some qualitative researchers is still being debated. The author argues that autoethnography contains strong narrative components or analysis with potential contribution to provide new understanding and to build knowledge. The article discusses criticisms against autoethnography, followed by its distinctive characteristics, which at the same time bring significant potential power. Clear guidelines and steps are needed to minimize biases and to bring about the potential power of autoethnography, and this article aims to address the issues through discussions on intersubjectivity, reflexivity, and ethics. At the end, it might be concluded that autoethnography is a method to investigate not merely the researchers, but to reveal certain phenomena and issues. Autoethnography is one good alternative among other methods that can contribute to developing understanding and knowledge through the construction of substantive theories about a particular issue.
