“…Fourth, we used recently recommended techniques to test dependent-group invariance in a dyadic structure. This involves modeling observed and latent factors in both groups in a single structure while accounting for the interrelationship between dyad members by adding covariances between cross-group latent factors and pairs of item errors [22,24]. We followed the recommended invariance-testing sequential order, comparing increasingly constrained models: configural (no equality constrains), metric (equal factor loadings) and scalar invariance (equal intercepts) [30,31].…”

“…Next, we examined the CDDUX measurement invariance across self-and parent-reports to establish its convergent validity. We utilized recently developed techniques to model dyadic data and their equivalence across time and groups (dyadic measurement invariance; e.g., [21][22][23][24][25]). These techniques allow us to statistically account for dependencies within dyads while retaining the power of dependent-group data analysis [21].…”

Objective The celiac disease quality of life questionnaire (CDDUX) is used widely in numerous languages worldwide. However, it's structural and construct validity and child-parent invariance had not been thoroughly examined. The objective of this study was to examine the psychometric properties of the 12-item CDDUX and the extent to which it meets the acceptable requirements of reliability and structural and convergent validity, as well as its child-parent invariance. Methods In this cross-sectional study, 126 dyads of children aged 8-18 years and their parents completed the Hebrew version self-report and parent-proxy report CDDUX. Recently developed methods to examine psychometric properties and to measure invariance of dyadic samples were used while properly accounting for nonindependence in measurement patterns. Results A three-factor structure, each with sufficient internal consistency, is confirmed for both children and parents. Removing a single indicator of the diet subscale resulted in full configural (χ 2 (181) = 202.277, P > 0.05, RMSEA = 0.026) and metric (χ 2 (189) = 209.543, P > 0.05, RMSEA = 0.043) invariance of the measure between children and parents. However, this occurred only in partial-scalar (χ 2 (198) = 229.813, P > 0.05, RMSEA = 0.031) and uniqueness invariance, which is nevertheless sufficient for meaningful comparison between the groups. Conclusion Overall, with minor modifications, the Hebrew version of the CDDUX was found to be a valid measure of children's celiac-related quality of life when measured across children's self-reports and parent-proxy reports. The CDDUX provides meaningful measurement and allows child-parent comparison.

“…As alluded to above, we believe that the statistical methods used for most of our research questions severely limit the speed of understanding mechanisms in this area of study. On the one hand, relationship researchers are certainly leaders in adopting newer methods to answer questions of process (e.g., contributing to new models on the longitudinal modeling of couple-related dynamics; Bolger & Laurenceau, 2013; Sakaluk et al, 2021). On the other hand, we do not yet see many of these models capturing reciprocal and recursive mechanisms in the study of relationships and health.…”

The study of intimate relationships and health is a fast-growing discipline with numerous well-developed theories, many of which outline specific interpersonal behaviors and psychological pathways that may give rise to good or poor health. In this article, we argue that the study of relationships and health can move toward interrogating these mechanisms with greater precision and detail, but doing so will require a shift in the nature of commonly used research methods in this area. Accordingly, we draw heavily on the science of behavior change and discuss six key methodologies that may galvanize the mechanistic study of relationships and health: dismantling studies, factorial studies, experimental therapeutics, experimental mediation research, multiple assessments, and recursive modeling. We provide empirical examples for each strategy and outline new ways in which a given approach may be used to study the mechanisms linking intimate relationships and health. We conclude by discussing the key challenges and limitations for using these research strategies as well as novel ideas about how to integrate this work into existing paradigms within the field.

“…In other words, the scaling of items is equivalent across partners. Scalar invariance indicates whether the amount of variation in each group is equivalent, and that each groups' mean differences are interpretable [51,52]. Power analyses for invariance testing suggests the use of changes in alternative fit indices (ΔAFI).…”

Background: The ability to understand another's emotions and act appropriately, empathy, is an important mediator of relationship function and health intervention fidelity. We adapted the Interpersonal Reactivity Index (IRI)an empathy scaleamong seroconcordant expectant couples with HIV in the Homens para Saúde Mais (HoPS+) triala cluster randomized controlled trial assessing couple-based versus individual treatment on viral suppressionin Zambézia Province, Mozambique. Methods: Using baseline data from 1332 HoPS+ trial participants (666 couples), an exploratory factor analysis assessed culturally relevant questions from the IRI. Because empathy is interdependent among couples, we validated the results of the exploratory factor analysis using a dyadic confirmatory factor analysis (CFA) with dyadic measurement invariance testing. Finally, we assessed the relationship between scores on our final scale and basic demographic characteristics (sex, age, education, and depression) using t-tests. Results: We found two subscales: 1) a seven-item cognitive empathy subscale (Cronbach's alpha 0.78) and 2) a six-item affective empathy subscale (Cronbach's alpha 0.73). The dyadic CFA found acceptable model fit and metric invariance across partners (Comparative Fit Index (CFI) = 0.914, Tucker Lewis Index = 0.904, Root Mean Squared Error of Approximation = 0.056, ΔCFI = 0.011). We observed higher cognitive (p: 0.012) and affective (p: 0.049) empathy among males and higher cognitive (p: 0.031) and affective (p: 0.030) empathy among younger participants. More educated participants had higher affective empathy (p: 0.017) and depressed participants had higher cognitive empathy (p: < 0.001). This two-subscale, 13-item version of the IRI measures cognitive and affective empathy in HoPS+ trial participants and adults while accounting for the interdependent nature of empathy within partner dyads. Conclusions: This scale will allow us to assess the interplay between empathy and other psychometric constructs (stigma, social support, etc.) in the HoPS+ trial and how each relates to retention in HIV, adherence to treatment, and prevention of maternal to child HIV transmission. Furthermore, this scale can be adapted for other sub-Saharan African populations, which will allow researchers to better assess HIV-related intervention efficacy. Trial registration: This study is within the context of the HoPS+ trial, registered at ClinicalTrials.gov as number NCT03149237. Registered May 11, 2017.
