Trajectories of Perceived Gratitude and Change Following Relationship Interventions: A Randomized Controlled Trial With Lower-Income, Help-Seeking Couples.

The current study was designed to advance basic and applied research on perceived gratitude from one's partner in established couple relationships. From a three-arm randomized controlled trial involving 615 lower-income, help-seeking couples (N = 1,224 individuals), study analyses examined (a) the trajectory of perceived gratitude from one's partner among couples assigned to the wait-list condition (i.e., absent of any intervention), and (b) changes in perceived gratitude for individuals assigned to either the OurRelationship (OR) or ePREP relationship intervention condition. With respect to the first aim, levels of perceived gratitude among wait-listed couples demonstrated no significant mean increase over the 6-month period; this rate of change was significantly different from rates of change observed in other relationship constructs (e.g., satisfaction, communication, support) during the wait-list period. Being married, female, and having more children were all associated with lower initial levels of perceived gratitude. For the second aim, individuals assigned to either the OR or ePREP treatment condition demonstrated significant improvements in levels of perceived partner gratitude compared to wait-listed couples. The magnitude of program effect sizes for gratitude (d = 0.33), however, was 3%-48% smaller compared to the magnitude of program effects of other relationship constructs (0.34 < d < 0.64). Results indicated that perceived gratitude is a distinct component of couple relationships, generally lower in more established relationships, and can be improved by participating in OR or ePREP relationship interventions. Implications for research and practice related to gratitude in couple relationships are discussed.

Skin-deep Resilience and Early Adolescence: Neighborhood Disadvantage, Executive Functioning, and Pubertal Development in Minority Youth.

Skin-deep resilience, in which youth overcome adversity and achieve success in psychological and academic domains but at a cost to their physiological well-being, has been documented in late adolescence and adulthood. However, its potential to emerge at earlier developmental stages is unknown. To address this gap, secondary data analyses were executed using waves 1 and 2 of the Adolescent Brain Cognitive Development study (n = 7712; ages 9-10 years at baseline [mean: 9.92; SD = 0.63]; 47.1% female; 66.1% White, 13.4% Black, and 20.6% Hispanic). The results indicated high levels of executive functioning were associated with improved psychological and behavioral outcomes at one-year follow-up. However, for racial and ethnic minority (i.e., Black or Hispanic) youth from disadvantaged neighborhoods, high levels of executive functioning were also associated with accelerated pubertal development. No significant interaction was observed among White youth. The findings suggest the skin-deep resilience pattern may be evident in early adolescence.

Strengthening couple functioning promotes resilience to COVID-19-related stressors among Black Americans.

The COVID-19 pandemic resulted in substantial hardship for Black Americans, leading to increased stress and mental health difficulties. We used longitudinal data from the Protecting Strong African American Families (ProSAAF) intervention study to test the hypothesis that improved couple functioning following ProSAAF participation would serve as a constructed resilience resource during the pandemic, buffering the impact of elevated pandemic-related stressors on change in depressive symptoms. We found that COVID-19-related stress predicted change in depressive symptoms from prepandemic to during the pandemic, that ProSAAF predicted improved couple functioning, and that positive change in couple functioning buffered the impact of pandemic stressors on change in depressive symptoms. These effects resulted in a significant indirect buffering effect of ProSAAF on the association between COVID-19-related stress and change in depressive symptoms through its effects on change in couple functioning. The results suggest that relationship intervention may increase resilience to unanticipated community-wide stress and promote mental health.

Changes in couple, parenting, and individual functioning following Family Expectations program participation.

The current study investigated changes in couple, parenting, and individual functioning following participation in Family Expectations, a relationship and parenting education program for new or expectant parents. The sample comprised 339 couples who participated in most sessions of the Family Expectations program and completed assessments at three different time points over a 12-month period. Study analyses examined: (a) change shortly following completion of the program, (b) associations between short-term change and subsequent change in outcomes at 12-month follow-up, and (c) differences in short-term change between married and unmarried couples. Significant improvements were observed in all three domains at short-term follow-up. Short-term changes, particularly for psychological distress, were predictive of long-term change in multiple domains. Few moderation effects by marital status were evident; those that appeared suggested stronger effects for married participants compared to unmarried. Study findings inform ongoing discussions into the utility of federally-funded relationship and parenting programming.

The protective effects of perceived gratitude and expressed gratitude for relationship quality among African American couples.

The current study was designed to investigate the protective effects of gratitude in romantic relationships. Particular attention was given to differentiating the beneficial effects of perceived gratitude (i.e., gratitude from one's partner, or feeling appreciated) versus expressed gratitude (i.e., gratitude to one's partner, or being appreciative) in mitigating the negative effects of ineffective arguing and financial strain on multiple indicators of relationship quality, both concurrently and longitudinally. The sample comprised 316 African American couples with three waves of data spanning approximately 16 months. Results indicated higher levels of perceived gratitude - but not expressed gratitude - weakened the association between relationship stressors and worsened outcomes (i.e., less satisfaction and confidence, more instability) at both between-person and within-person levels. Concurrently, perceived gratitude exhibited protective effects with respect to ineffective arguing and financial strain; longitudinal protective effects were observed only with respect to ineffective arguing. Results highlight the ways in which perceiving gratitude from one's partner, both at a single instance and sustained over many months, can be protective for multiple facets of relationship quality. Collectively, findings underscore the importance of interpersonal gratitude for romantic relationships and its merit for increased attention in research and practice.

Childhood poverty, immune cell aging, and African Americans' insulin resistance: A prospective study.

The present study investigated developmental pathways that can contribute to chronic disease among rural African Americans. With a sample of 342 African American youth (59% female) from the southeastern United States followed for nearly two decades (2001-2019), we examined the prospective association between family poverty during adolescence (ages 11-18) and insulin resistance (IR) in young adulthood (ages 25-29) as well as underlying biological and psychosocial mechanisms. Results indicated family poverty during adolescence forecast higher levels of IR in young adulthood, with accelerated immune cell aging at age 20 partially mediating this association. Serial mediational models confirmed the hypothesized pathway linking family poverty, perceived life chances, cellular aging, and IR. Findings provide empirical support for theorized developmental precursors of chronic disease.

Adolescent Substance Use and Individual Beliefs That Drug Use Is Wrong: A Statewide Epidemiological Study.

OBJECTIVE: Informed by cognitive dissonance theory, the current study investigated the ability of youths' belief that drug use is wrong to predict likelihood of past year substance use abstinence as well as frequency of use at grades 8, 10, and 12. METHOD: Study analyses were executed from a statewide epidemiological survey of more than 125,000 youth using multi-group Zero-Inflated Poisson regression modeling. RESULTS: Personal belief that drug use is wrong demonstrated the largest magnitude of effect at each grade among the individual, family, and school-based factors under examination; this finding emerged with respect to predicting past year substance use abstinence as well as rates of substance use among individuals reporting past year use. Although differences across grades were evident for the magnitude of effect within various risk and protective factors, the rank ordering in magnitude of effect between factors was consistent across grades 8, 10, and 12. CONCLUSION: Current results underscore the salience of youths' belief that drug use is wrong in explaining likelihood of past year substance use at multiple time points during adolescence.Supplemental data for this article is available online at https://doi.org/10.1080/10826084.2022.2034877 .

African Americans' relationship quality and depressive symptoms: A longitudinal investigation of the Marital Discord Model.

The present study was designed to examine the complex bidirectional associations between relationship quality and depressive symptoms among African American couples. Informed by the Marital Discord Model, particular attention was devoted to understanding the unique associations of positive and negative dimensions of relationship functioning with depressive symptoms over time, the time frames over which these effects occur, and the model's applicability for African American couples. One hundred seventy-four African American couples (N = 348 individuals) provided information on depressive symptoms, relationship satisfaction, ineffective arguing, and partner support four times over a 25-month period. Hypotheses were tested using Random-Intercept Cross-Lagged Panel Models to separate between- and within-person effects. Results indicated that between-person associations with depressive symptoms were significant for relationship satisfaction (negative association) and ineffective arguing (positive association), but not partner support. Within-person concurrent effects were also significant with depressive symptoms and each of the relationship processes under investigation. Within-person 8-month lagged effects were only significant for partner support and depressive symptoms (negative association); these effects were significant in both directions, but stronger from support to depressive symptoms than from depressive symptoms to support. Study findings provide increased conceptual and analytic precision for understanding the association between couples' relationship quality and African Americans' mental health, including malleable relationship factors that can be targeted in family-focused interventions to promote individual and couple well-being.

Family-centered prevention buffers the effect of financial strain on parenting interactions, reducing youth conduct problems in African American families.

OBJECTIVE: This study examined whether a family-focused prevention program for African American families could buffer the negative effect of perceived financial strain on protective parent-child interactions and thereby reduce the indirect effect of financial strain on youth conduct problems. METHOD: Three hundred and forty-six African American couples with an early adolescent child (M age = 10.9 years at Wave 1 [W1]) participated. Families were randomly assigned to the Protecting Strong African American Families (ProSAAF) prevention program or to a no-treatment control condition and provided data prerandomization (W1) and postintervention, Wave 2 (W2), 9.4 months after W1. Youth and both parents reported family financial strain at W1 and protective parent-child interactions at W1 and W2. Youth reported their conduct problems at W1 and W2. Hypotheses were tested using moderated mediation analyses. RESULTS: ProSAAF significantly moderated the negative effect of youth-reported financial strain on changes in protective parenting interactions such that financial strain was not significantly associated with changes in protective parenting among the intervention group, thus reducing the indirect effect of financial strain on increases in youth conduct problems among this group. Parent-reported financial strain was not significantly associated with changes in protective parenting in either condition, precluding the potential for stress buffering intervention effects. CONCLUSIONS: The ProSAAF prevention program buffered the negative effect of youth-reported financial strain on protective parenting interactions and reduced its indirect effect on youth conduct problems. These findings suggest that family-focused prevention has the potential to promote resilience among African American youth perceiving family financial strain.

Trajectories of relationship and individual functioning among waitlisted couples for an online relationship intervention.

To inform research and practice with distressed couples, the current study was designed to examine patterns of change among distressed, help-seeking couples prior to receiving an intervention. Data from this study originate from 221 couples assigned to the waitlist control condition of a randomized controlled trial for couples seeking online help for their relationship. All couples self-selected into the online program and agreed to withhold seeking additional services for their relationship during the waitlist period. In contrast with prior findings, results from the current study indicated a general pattern of mean improvement in both self-reported relationship functioning (e.g., increased relationship satisfaction, partner emotional support) and self-reported individual functioning (i.e., decreased psychological distress, anger) over the six-month waitlist period. Nonetheless, the majority of couples continued to remain relationally distressed despite these improvements. Findings from the study indicate that distressed couples can, in fact, exhibit some degree of improvement absent of intervention. At the same time, overall levels of distress remained elevated, indicating that these improvements are not sufficient to result in high levels of functioning and suggesting that many distressed couples may benefit from empirically supported programs to realize greater gains. These results also highlight and underscore the importance of including control conditions in studies examining the efficacy of relationship interventions with distressed couples to ensure that any observed improvements in relationship functioning are attributable to the intervention rather than to naturally occurring changes.

Con el fin de orientar la investigación y la práctica con parejas con distrés, se diseñó el presente estudio para analizar patrones de cambio entre parejas con distrés que buscan ayuda antes de recibir una intervención. Los datos de este estudio surgen de 221 parejas asignadas al grupo comparativo de lista de espera de un ensayo controlado aleatorizado para parejas que buscaban ayuda virtual para su relación. Todas las parejas eligieron ellas mismas estar en el programa virtual y acordaron dejar de buscar otros servicios para su relación durante el periodo de lista de espera. A diferencia de los resultados anteriores, los de este estudio indicaron un patrón general de mejoría promedio tanto en el funcionamiento relacional autoinformado (p. ej.: mayor satisfacción con la relación y apoyo emocional de la pareja) como en el funcionamiento individual autoinformado (p. ej.: menos distrés psicológico y enfado) durante el periodo de seis meses en lista de espera. Sin embargo, a pesar de estas mejorías, la mayoría de las parejas continuó teniendo distrés relacional. Los resultados del estudio indican que las parejas con distrés pueden, de hecho, mostrar algún grado de mejoría sin intervención. Al mismo tiempo, los niveles generales de distrés se mantuvieron elevados, lo cual indica que estas mejorías no son suficientes para dar como resultado niveles altos de funcionamiento, y sugiere que muchas parejas con distrés pueden beneficiarse de programas basados en la experiencia para lograr mayores avances. Estos resultados también destacan y subrayan la importancia de incluir grupos comparativos en los estudios que analizan la eficacia de las intervenciones en las relaciones de parejas con distrés a fin de garantizar que las mejorías observadas en el funcionamiento relacional sean atribuibles a la intervención en lugar de a los cambios que se producen naturalmente.

Family-Centered Prevention Effects on the Association Between Racial Discrimination and Mental Health in Black Adolescents: Secondary Analysis of 2 Randomized Clinical Trials.

Importance: Some Black adolescents who frequently experience racial discrimination develop mental health problems. Protective caregiving may buffer adolescents from the negative mental health outcomes associated with experiencing racial discrimination. Objective: To examine if participation in programs that enhance protective caregiving will attenuate the positive association between Black adolescents' encounters with discrimination and subsequent increases in mental health problems. Design, Setting, and Participants: This secondary analysis used data from 2 randomized clinical trials testing family-centered prevention programs: the Strong African American Families-Teen (SAAF-T) program and the Adults in the Making (AIM) program. The programs were implemented in community locations convenient for participants in 12 rural Georgia counties. For the SAAF-T trial, Black adolescents and their primary caregivers were recruited from 2007 to 2008. In the AIM trial Black adolescents and their primary caregivers were recruited from 2006 to 2007. Data for this study were analyzed from June to August 2020. Exposures: Adolescents provided data at baseline on the frequency of their encounters with racial discrimination. Treatment group participants in each trial took part in a family-centered prevention program designed to prevent substance use and mental health problems. SAAF-T is a 5-session, 10-hour psychosocial intervention for families with a Black adolescent aged 14 to 16 years. AIM is a 6-session, 12-hour psychosocial intervention for families with a Black youth who is a high school senior. Main Outcomes and Measures: The primary outcomes were mental health problems, including conduct problems and depression or anxiety symptoms. Results: The SAAF-T study included 502 Black adolescents (mean [SD] age, 16.0 [0.6] years; 281 [56.0%] girls), including 252 randomized to the intervention and 250 randomized to the control, and the AIM trial included 367 Black adolescents (mean [SD] age, 17.7 [0.8] years; 217 [59.1%] girls and women), including 187 randomized to the intervention and 180 randomized to the control. Adolescents assigned to the SAAF-T intervention group who frequently experienced discrimination at baseline evinced fewer subsequent increases in conduct problems (incident risk ratio, 0.530 [95% CI, 0.340 to 0.783]). Adolescents assigned to the AIM intervention group who frequently experienced discrimination at baseline evinced fewer subsequent increases in conduct problems (mean difference, -0.361 [95% CI, -0.577 to -0.144]) and fewer subsequent increases in depression or anxiety symptoms (mean difference, -0.220 [95% CI -0.402 to -0.038]). Moderated mediation analyses suggested that enhanced protective caregiving was partially responsible for all observed interaction effects (indirect effect: SAAF-T conduct problems, -0.063 [95% CI, -0.127 to -0.001]; AIM conduct problems, -0.048 [95% CI, -0.095 to -0.001]; AIM depression or anxious symptoms, -0.036 [95% CI, -0.074 to 0]). Conclusions and Relevance: This secondary analysis of 2 randomized clinical trials found that participation in family-centered preventive interventions attenuated the association between frequent exposure to discriminatory behaviors and subsequent mental health problems. Notably, all but 1 of the treatment and moderated-mediation findings were reproduced across the SAAF-T and AIM trials. Trial Registrations: ClinicalTrials.gov Identifiers: SAAF-T, NCT04501471; AIM, NCT04510116.

Opioid use at the transition to emerging adulthood: A latent class analysis of non-medical use of prescription opioids and heroin use.

BACKGROUND: Although rates of nonmedical opioid use are highest in late adolescence and emerging adulthood, efforts to understand the extent of the heterogeneity in opioid misuse during this time have been limited. The current study aimed to derive and define typologies of opioid use in high school students at the onset of emerging adulthood. METHODS: Survey responses from a statewide sample of high school students aged 18 and 19 (N = 26,223) were analyzed. Group-based comparisons between participants reporting opioid use and those not reporting opioid use were conducted. Among those reporting opioid use (n = 1,636), we conducted a latent class analysis (LCA) to identify heterogeneous subgroups of opioid users on the basis of non-medical use of prescription opioids (NMUPO) and heroin use. The resulting classes were then compared across various risk and protective factors using multinominal logistic regression. RESULTS: Consistent differences were observed between participants using opioids and participants not using opioids, with moderate to large effect sizes. Results from LCA revealed three subclasses: NMUPO-Any Use, NMUPO To Get High, and Heroin Use. Subclass differences were observed for non-opioid substance use, mental health, and demographics. CONCLUSIONS: Findings from this study underscore the variability of youth who engage in opioid use in late adolescence. Results also indicate that opioid use during adolescence is likely indicative of a broader set of substance use and mental health issues.

Can Interventions that Strengthen Couples' Relationships Confer Additional Benefits for their Health? A Randomized Controlled Trial with African American Couples.

This study examined the effects of the Protecting Strong African American Families (ProSAAF) prevention program on adults' self-reported health outcomes 25 months after enrollment. ProSAAF is a couple-focused prevention program specifically designed to meet the needs of African-American families residing in the rural South. African-American couples (N = 346) with an early adolescent child participated in a randomized controlled trial of the program. Dyadic data analyses indicated significant direct effects on changes in couple functioning post-intervention as well as significant indirect effects of ProSAAF on changes in health through post-intervention improvements in couple functioning. These benefits were documented for men's and women's general health, depressive symptoms, and problematic sleep. There were no significant direct effects of ProSAAF participation on changes in health. Findings provide tempered optimism regarding the potential benefits of couple-focused programming for adults' physical, mental, and behavioral health.

The complexities of family mealtimes in the 21st century: A latent profile analysis.

The goal of the present study was to characterize more than 500 families regarding family mealtime organization patterns. Family profiles were developed based on patterns detected across a set of sociological and psychological variables. Latent profile analyses indicated three distinct subgroups of families: Food Secure and Organized (55% of the sample), Very Low Food Security and Disorganized (27%), and Low Food Security and Organized (18%). Examination of group membership correlates revealed significant differences related to family mealtime behaviors and food preparation strategies, but not food shopping location or areas of requested change around family mealtimes. Findings highlight homogenous subgroups of families on the basis of co-occurring psychological and sociological factors pertinent to family mealtimes, with those families possessing the highest levels of risk in multiple domains also reporting family mealtime organization patterns associated with less healthy eating. Findings provide a snapshot into the organization, and complexities, of family meals for the American family today, highlighting the need for researchers and practitioners interested in promoting healthy food intake within American families to consider both psychological and sociological factors that influence family mealtime organization.

Direct and indirect effects of a couple-focused preventive intervention on children's outcomes: A randomized controlled trial with African American families.

OBJECTIVE: This study examined the effects of the Protecting Strong African American Families (ProSAAF) prevention program on children's outcomes more than 2 years after enrollment, including direct effects of the intervention and indirect effects through couple functioning and parent-child relations. METHOD: Three hundred forty-six African American couples with an early adolescent child participated; all families lived in rural, low-income communities in the southern United States. Families were randomly assigned to ProSAAF or control conditions and completed four waves of data collection. Couples reported couple functioning at baseline (Wave 1) and at 9-month follow-up (Wave 2), and parent-child relations at 17-month follow-up (Wave 3). Children reported their conduct problems, affiliation with deviant peers, substance use, sexual onset, depressive symptoms, and self-control at 25-month follow-up (Wave 4). RESULTS: Path analyses indicated significant indirect effects of ProSAAF on children's outcomes through improvements in couple functioning and better parent-child relations. There were no significant direct effects of the intervention on children's outcomes or significant indirect effects through couple functioning alone. CONCLUSIONS: This couple-focused prevention program has positive indirect effects on several child outcomes through the intervening processes of promoting improvements in couple functioning and better parent-child relations. These findings provide cautious optimism regarding the possible benefits of couple-focused programming on participants' children while suggesting ways in which future couple-focused interventions could yield stronger effects on these youth.

If You Host It Online, Who Will (and Will Not) Come? Individual and Partner Enrollment in a Web-Based Intervention for Distressed Couples.

Given the increasing utilization of online recruitment and delivery for prevention programming, the current study was designed to examine the ways in which recruitment and eligibility factors affect the resulting size and composition of participants in an online intervention. Study hypotheses were tested from a sample of 2512 low-income individuals who sought to enroll in OurRelationship, a web-based intervention for distressed couples. Results indicated that more than half of the sample (62%) learned about the OurRelationship program from results of an online search engine. Differences in participant characteristics were observed on the basis of recruitment source, with individuals recruited from an online search and from social media being characterized by higher levels of relationship distress and personal psychological distress relative to those who learned about the program through other means. Partner participation requirements also had a significant effect on the final sample of participants, as more than half of help-seeking individuals (52%) had partners who did not complete the screening enrollment form and were thus ineligible to receive services. Furthermore, compared with individuals whose partners completed the enrollment form, individuals whose partners did not participate were characterized by greater levels of break-up potential, physical aggression, communication conflict, psychological distress, and anger. Findings from the study suggest that some, but not all, online sources recruit more at-risk populations as well as illustrate the ways in which partner participation requirements can screen out interested individuals that appear in most need of services. Implications for prevention researchers and practitioners are discussed.

Why now? Examining antecedents for substance use initiation among African American adolescents.

Current adolescent substance use risk models have inadequately predicted use for African Americans, offering limited knowledge about differential predictability as a function of developmental period. Among a sample of 500 African American youth (ages 11-21), four risk indices (i.e., social risk, attitudinal risk, intrapersonal risk, and racial discrimination risk) were examined in the prediction of alcohol, marijuana, and cigarette initiation during early (ages 11-13), mid (ages 16-18), and late (ages 19-21) adolescence. Results showed that when developmental periods were combined, racial discrimination was the only index that predicted initiation for all three substances. However, when risk models were stratified based on developmental period, variation was found within and across substance types. Results highlight the importance of racial discrimination in understanding substance use initiation among African American youth and the need for tailored interventions based on developmental stage.

Peer influence, Frontostriatal connectivity, and delay discounting in African American emerging adults.

Prior research has demonstrated the importance of delay discounting in adverse health behaviors, such as addiction, attention deficit hyperactivity disorder, risk taking, and obesity. Nevertheless, the functional connectivity of neural circuitry associated with delay discounting and the ways in which the social environment may influence frontostriatal connectivity remain largely unknown, particularly in African Americans. Building on recent literature implicating frontostriatal connectivity during active delay discounting decision making and at rest, we used functional magnetic resonance imaging to assess the association between delay discounting and frontostriatal resting state connectivity (rsFC). We also examined the capacity of social relationships with parents and peers to longitudinally predict frontostriatal rsFC. The study cohort was composed of 91 rural African American emerging adults followed over a 6-year period. Greater (i.e., more positive) frontostriatal rsFC was associated with decreased delay discounting (i.e., less impulsive decision making). In addition, peer relationships at ages 20 and 21 significantly predicted frontostriatal rsFC at age 25 above and beyond parental influence. A significant indirect effect of peer affiliation on delay discounting through frontostriatal rsFC also emerged. These results indicate a role of frontostriatal connectivity in delay discounting decision making and highlight peers' unique influence on decision making behaviors through frontostriatal rsFC during emerging adulthood.

Trajectories of relationship confidence in intimate partnerships.

The current study examined trajectories of relationship confidence, defined as the belief that oneself and the partner together have the skills needed to navigate conflict and maintain a partnership into the future. This study uses data from a sample of 1,294 partnered but unmarried young adults to examine trajectories of relationship confidence across 11 waves of assessment over more than 4 years and the between- and within-person predictors of those trajectories. On average, relationship confidence was high at the outset of the study and remained stable over time. Underlying the overall stability, however, men's and women's trajectories flowed in opposite directions. Women started with more confidence than men, and their confidence decreased over time while men's increased, although the analysis of individuals rather than couples must be considered when interpreting this finding. Individuals in longer partnerships, who were cohabiting at Wave 1, with lower levels of avoidant attachment, more frequent positive interactions and higher satisfaction at Wave 1, and those who married during the study, had higher initial relationship confidence. Having children with a prior partner predicted lower initial confidence and faster decreases over time only for women. At the within-person level, relationship confidence was higher than usual at waves when more positive interactions, less negative interactions, and higher relationship satisfaction were reported, particularly for women. Results highlight the substantial variability in trajectories of relationship confidence among individuals in unmarried relationships as well as an array of factors that influence its development.

"Will you complete this survey too?" Differences between individual versus dyadic samples in relationship research.

This study examines the ways in which collecting data from individuals versus couples affects the characteristics of the resulting sample in basic research studies of romantic relationships. From a nationally representative sample of 1,294 individuals in a serious romantic relationship, approximately half of whom were randomly selected to invite their partner to participate in the study, we compare relationship, individual, and demographic characteristics among 3 groups: individuals randomized to invite their partner and whose partner participated in the study, individuals randomized to invite their partner but whose partner did not participate, and individuals who were not randomized to invite their partner. Results indicated that individuals whose partner participated reported the highest levels of relationship and individual well-being relative to comparison groups, as well as individuals who participated alone despite being asked to invite their partner, reported the lowest levels of relationship and individual well-being relative to comparison groups. Effect size magnitudes indicated the strongest group differences with respect to relationship variables, particularly cognitive appraisals of overall relationship stability and satisfaction. Implications for romantic relationship research and study design are discussed. (PsycINFO Database Record (c) 2020 APA, all rights reserved).
