Perceived Emotional Invalidation, Psychological Distress and Relationship Satisfaction in Couples: An Actor-Partner Interdependence Mediation Analysis.

Research has demonstrated a clear link between perceived emotional invalidation and increased psychological distress. However, available studies have predominantly focused on individual data, and leave the impact on relationship satisfaction largely unexplored. Considering the systemic-transactional model, our study aimed to examine the association between perceived emotional invalidation, psychological distress, and couple relationship satisfaction from a dyadic perspective. We conducted a cross-sectional study involving 240 mixed-gender couples from Portugal employing the Actor-Partner Interdependence Mediational Model to analyse the data to examine actor and partner direct and indirect effects. Results showed that, for both women and men, own perceived emotional invalidation was associated with own psychological distress but not with own relationship satisfaction. Also, own psychological distress was associated with own relationship satisfaction but only for women. Finally, one actor and one partner indirect effects were found. Women perceived emotional invalidation was associated with their own psychological distress which in turn contributed to lower levels of relationship satisfaction for both them and their partners. This study contributes to a deeper understanding of the dyadic effects of perceived emotional invalidation on psychological distress and relationship satisfaction within romantic relationships identifying interpersonal emotional dynamics as an important target of interventions.

Examining within- and between-member cohesion and working alliance effects on group members' motivation: a preliminary actor-partner interdependence study.

OBJECTIVE: Informed by the person-environment fit theory, this preliminary study examined if a fit between a group member's treatment experience and their working therapy context (other group members' aggregated treatment experiences) were related to their level of motivation within a group treatment for healing from internalized weight stigma. METHOD: We examined the relationship between two types of within-member and between-member's group cohesion, working alliance, and motivation. Specifically, we utilized the Actor-Partner Interdependence Model to operationalize the impact of actor's within-member cohesion and alliance (personal changes over time) and between-member cohesion and alliance (individual differences) as well as partner's within-member cohesion and alliance (contextual changes over time) and between-member cohesion and alliance (contextual differences) on group members' motivation. This study utilized self-report data from 26 group members who participated in three online weight stigma psychotherapy groups. RESULTS: For cohesion, results suggested that the relationship between partner within-member cohesion and motivation was larger for members who reported low cohesion across all the sessions compared to the other members of their group. Additionally, an individual group member who perceived a group session more cohesive than they did on average, reported increased motivation in that session, and this relationship was stronger for members who on average perceived their group less cohesive than other group members. Lastly, session-level alliance was more strongly associated with an individual member's motivation in that session when the other group members reported lower group alliance on average. CONCLUSIONS: These findings underscore the significance of member-group fit in group therapy and the reciprocal impact of individual members and the group on each other's therapy outcomes.

Relationship between marital satisfaction and defeat in IVF-ET: based on actor-partner interdependence model approach.

OBJECTIVE: A person's marital satisfaction is a strong predictor of their own mental health outcomes. However, marital satisfaction results from both spouses' experiences, so a partner's marital satisfaction also affects his or her mental health outcomes. This study adopted the actor-partner interdependence model approach (APIM) to evaluate the relationship between marital satisfaction and sense of defeat in vitro fertilization-embryo transfer (IVF-ET) couples. METHODS AND MEASURES: In this cross-sectional study, 181 infertile couples undergoing IVF-ET treatment were recruited using the Marital Satisfaction Scale of the ENRICH Marital Quality Questionnaire and Defeat Scale. Through APIM and Pearson analysis, the path relationship between marital satisfaction and defeat was analyzed. RESULTS: The varying degrees of defeat in IVF-ET couples, are closely related to actors' and partners' marital satisfaction. In terms of actor effects, the Marital Satisfaction of both husbands (ß = -0.71, p < 0.001) and wives (ß = -0.46, p = 0.001) have a significant effect on individual Defeat. With regard to partner effects, husbands' Marital Satisfaction (ß = -0.23, p = 0.038) has a significant impact on wives' Defeat and the wives' Marital Satisfaction (ß = -0.45, p = -0.005) has a significant impact on husbands' Defeat. CONCLUSION: IVF-ET couples must be looked at as a whole, and it is critical to include couples and not just men or women when studying infertility. The importance of their interaction is essential to improve the psychosocial adaptation of infertile couples in IVF-ET treatment.

Association between stigma and quality of life among chronic refractory wounds patients and informal caregivers: an actor-partner interdependence model analysis.

PURPOSE: The co-occurrence of health impairments in patients and their informal caregivers may be particularly common in intimate care settings in China. Patients with Chronic Refractory Wounds (CRWs) and their informal caregivers constitute a dyad and exhibit dyadic effects during the caring process. Unfortunately, no study has yet explored the dyadic effects of stigma on the QoL of patients with CRWs and their caregivers. METHODS: We used a convenience sampling method and recruited CRWs patient-caregiver dyads (N = 207) in China between April 2022 and October 2023. RESULTS: We found that: (i) dyadic members experience varying degrees of stigma; (ii) the actor-partner effect of CRWs patients' stigma on their own and their informal caregivers' QoL was significant (Path A1: ß = - 1.27, Path A2: ß = - 0.37, Path P1: ß = - 0.08, Path P2: ß = - 0.18); (iii) informal caregivers' stigma adversely affects both their own and their patients' psychological QoL((Path A4: ß = - 0.65, Path P4: ß = - 0.52)). Informal caregivers' stigma can negatively impact patients' physical QoL (Path P3: ß = - 0.17), whereas it does not significantly affect their own physical QoL. CONCLUSION: There is a notable actor-partner effect of the CRWs patients' stigma on their own and their informal caregivers' QoL. CRWs patients' stigma should become a priority for the government to improve CRWs patients' and informal caregivers' QoL. Besides, health professionals should be addressing several assessments and interventions to decrease informal caregivers' affiliate stigma symptoms and improve CRWs patients' and informal caregivers' QoL.

Congruence Between Older Chinese Immigrants and Their Adult Children on Hospice Attitudes and Preferences: An Actor-Partner Interdependence Model.

Objectives: This study investigates the alignment of awareness, attitudes, and preferences regarding hospice care between older Chinese immigrants and their adult children. Methods: Forty older Chinese immigrants and their adult children in New York City were assessed for their awareness, attitudes, and preferences for hospice care. McNemar's and Cohen's Kappa tests examined differences and congruence within parent-child dyads. The Actor-Partner Interdependence Model (APIM) was employed for dyadic analysis using structural equation modeling (SEM). Results: Discrepancies were observed between older parents and adult children, with the latter showing higher awareness and more positive attitudes toward hospice care compared to their parents. While 84.2% of older parents expressed willingness to accept hospice care, only 65.7% of their children believed their parents would desire hospice, and only 39.5% of children expressed a preference for hospice care for their parents. Kappa coefficients indicated poor-to-slight agreement within parent-child dyads, but there was a fair level of agreement in children's perceptions of their parents' preferences and their own preferences for parents. APIM revealed significant actor effects but nonsignificant partner effects, suggesting that parents' and children's preferences are influenced by their own attitudes, but not by those of other family members within the parent-child dyads. Conclusion: The incongruence in attitudes and preferences for hospice care between Chinese immigrant older adults and their children emphasizes the need for culturally-informed education and interventions to facilitate open conversations and ensure patient-centered end-of-life care for older Chinese immigrants.

Relationship between dyadic coping, resilience and fear of childbirth in expectant couples: An actor-partner interdependence model approach.

BACKGROUND: Fear of childbirth is a common concern in pregnant women and their spouses due to the unpredictability of the process and outcome of a delivery, which results in adverse effects on mental health, birth outcomes and family intimacy. However, there is a lack of studies that explore the influencing factors of fear of childbirth among expectant couples from a dyadic perspective. The aim of this study is to explore the correlation of dyadic coping, resilience and fear of childbirth in pregnant couples and to construct an actor-partner interdependence model to verify dyadic effects. METHODS: This cross-sectional survey included 420 couples and was conducted between November 2022 and March 2023 in the obstetric department at two hospitals in China. Convenience sampling and an actor-partner interdependence model was used. FINDINGS: The prevalence of fear of childbirth among pregnant women and their spouses is 37.4 % and 33.1 %, respectively. Women's resilience and dyadic coping had a partner effect on spouses' fear of childbirth, in addition to an actor effect on their own fear of childbirth. Spouses' resilience and dyadic coping had only actor effects on themselves, and no partner effect was found on the pregnant women. CONCLUSION: Women's fear of childbirth was positively associated with spouses' fear of childbirth. Interventions for fear of childbirth should include improving resilience and enhancing dyadic stress support and coping. This study provides empirical evidence for future clinical research and interventions on the psychological status of pregnant women and their partners during pregnancy.

Factors effecting on health-promoting behaviors in iranian pregnant women and their husbands: the actor-partner interdependence model (APIM).

INTRODUCTION: Pregnancy is an important period of life for women and their husbands as the couple's health is essential. The present study evaluated the impact of some factors (marital adjustment with depressive symptoms) on health-promoting behaviors in pregnant women and their husbands based on the actor-partner interdependence model (APIM). MATERIALS AND METHODS: This descriptive study examined 211 couples (pregnant women and their husbands) in pregnancy clinics of Babol University of Medical Sciences using a convenience sampling method. The participants completed Spanier's Dyadic Adjustment Scale (DAS) (1979), Edinburgh Postnatal Depression Scale (EPDS) (1987), and Walker's Health Promoting Lifestyle Profile II (HPLPII) questionnaire (1997). The relationships between women and their husbands were also evaluated using structural equation modeling with R software according to the Lavaan (latent variable analysis) package based on APIM-SEM. RESULTS: The pregnant women's marital adjustment positively affected their health-promoting behaviors (ß = 0.456, 95% Cl: 0.491-0.998, p < 0.001) and their husbands' (ß = 0.210, 95% Cl: 0.030-0.726, p = 0.048). Pregnant woman's depressive symptoms also negatively affected their health-promoting behaviors (ß=-0.088, 95% Cl: -0.974-0.074, P = 0.236) and their husbands' health-promoting behaviors (ß=-0.177, 95% Cl: -0.281 - -0.975, P = 0.011). Furthermore, the husband's marital adjustment only positively affected his studied behaviors (ß = 0.323, 95% Cl: 0.0303-0.895, P < 0.001) but did not affect the pregnant woman's health behaviors. The husband's depressive symptoms had a negative impact on his studied behaviors (ß = 0.219, 95% Cl: -0.122 - -0.917, P = 0.001) and did not affect the pregnant woman's depressive symptoms. Our findings confirmed the mediating role of depressive symptoms in pregnant women and their husbands on the association of marital adjustment and health-promoting behaviors. According to the actor-partner study, a pregnant woman's marital adjustment scores positively affected her studied behaviors and her husband (ß = 0.071, 95% Cl: 0.042-0.278, P = 0.015) by decreasing her depression score. Therefore, the husband's marital adjustment score positively affected his studied behaviors by decreasing his depression score (ß = 0.084, 95% Cl: -0.053 -0.292, P = 0.005), and it did not affect his wife's health-promoting behaviors. DISCUSSION AND CONCLUSION: These findings suggest healthcare providers, obstetricians, and psychologists evaluate the husbands' symptoms of depression and health-promoting behaviors in the routine pregnancy care of pregnant women. They also pay great attention to marital adjustment as a determinant of reducing depressive symptoms in pregnant women and their husbands.

Testing the Associations Between Attachment Anxiety, Relational Aggression and Depressive Symptoms in Romantic Relationships: Actor-Partner Interdependence Model and Actor-Partner Interdependence Mediator Model.

Emerging adulthood is a pivotal period for romantic relationships, yet the specific mechanisms through which attachment anxiety influences relationship dynamics and psychological outcomes in this phase are poorly understood. Particularly, in the context of romantic dyads, understanding how partners' behaviors and emotional patterns reciprocally influence each other remains underexplored. This study utilizes the Actor-Partner Interdependence Model and Actor-Partner Interdependence Mediator Model to explore the relationship between attachment anxiety,relational aggression (both perpetration and victimization), and depressive symptoms among emerging adults. A sample of 138 mixed-sex emerging adulthood couples from China, was recruited (Mage = 21.40, SD = 2.54; 50% female, 62.6% reporting that this relationship was ongoing for more than a year). Attachment anxiety significantly predicted relational aggression in both partners, with male attachment anxiety also significantly predicted female relational aggression. Significant indirect effects of both partners' relational aggression perpetration and victimization on their own and each other's relationship between attachment anxiety and depressive symptoms. These findings contribute to understanding the intricate dynamics of attachment anxiety and relational aggression in romantic relationships during emerging adulthood, emphasizing the need for targeted interventions to mitigate these risks.

The Relationship between Addictive Use of Short-Video Platforms and Marital Satisfaction in Older Chinese Couples: An Asymmetrical Dyadic Process.

Increasing evidence indicates that the addictive use of social media can have a detrimental effect on marital satisfaction, due mainly to the decrease in time and focus given to one's spouse. However, the impact of social media use among older couples remains under-investigated, and the research that does exist relies on individual-level data that do not allow the exploration of the dynamics between the dyadic partners. Therefore, the present study focused on older adults' use of short-video platforms, as these have been shown to be particularly addictive for older adults. A sample of 264 older couples was gathered (meanage = 68.02, SD = 8.68), and both spouses completed surveys reporting addictive use of short-video platforms, negative emotions, and marital satisfaction. Using an actor-partner interdependence model, we found an asymmetrical dyadic process in that the addictive use of short-video platforms by the wives was not only related to their own negative emotions, but also those of their spouse, as well as to decreased marital satisfaction. Meanwhile, addictive use by the husbands seemed to relate only to their own increased negative emotions, as well as to decreased marital satisfaction. Together, the findings from this study reveal dyadic dynamics with delineated pathways through which the addictive use of short-video platforms can damage older couples' interactive processes and marital satisfaction.

Is passion contagious in coach-athlete dyads? A dyadic exploration of the association between passion, affective and need-based experiences in individual sports.

The Dualistic Model of Passion distinguishes between harmonious and obsessive passion, which are associated with athletes' and coaches' adjustments. Whereas prior research sampled either athletes or coaches, the present study used a dyadic approach to explore the bidirectional influence of passion on affective experiences in coaches and athletes. Using a cross-sectional dyadic design, 198 coach-athlete dyads involved in an individual sport at different competition levels, reported on their passion, need-based, and affective experiences. Both actor effects (i.e., intrapersonal dynamics within athletes or coaches) and partner effects (i.e., interpersonal dynamics from coach to athlete and vice versa) were examined. Furthermore, dyadic mediation models were used to investigate the potential mediating role of need-based experiences in the association between passion and affective experiences. Results unveiled compelling evidence for actor effects, indicating that one's own harmonious passion was positively related to one's own more adaptive outcomes and negatively to one's own more maladaptive outcomes, whereas obsessive passion was positively related to maladaptive outcomes. Further, very limited evidence for partner effects, in which coaches' passion affected athletes' outcomes or vice versa, was found. The dyadic mediation models underscored the role of need-based experiences in mediating the association between passion and affective experiences, but only at the intrapersonal level. As such, one's own passion experiences were related to one's own need-based experiences, which in turn were related to one's own affective experiences. The study provided no evidence for interpersonal mediation effects.

Childcare sharing and family happiness: analyzing parental and child well-being in the actor-partner interdependence model.

Introduction: The exploration of the relationship between parental and child happiness, particularly in the context of shared childcare responsibilities, has not been examined in Korean families. Methods: Using a two-wave longitudinal design and data from 1,403 families from the Panel Study on Korean Children, this study employed the actor-partner interdependence model to examine the dynamics of childcare sharing between mothers and fathers in South Korea. Results: Mothers' childcare sharing was found to have no significant impact on their own and their partner's happiness, reflecting traditional gender norms that undervalue mothers' contributions. In contrast, fathers' childcare sharing had a positive impact on their own and their spouse's happiness, suggesting a growing recognition of fathers' involvement. Furthermore, fathers' active participation in childcare was found to promote their children's happiness through their own happiness. Discussion: This study reflects the complexity of evolving family roles and the covert persistence of traditional gender roles in modern Korean parenting. It suggests the importance of work and family policies that support changes in family dynamics by providing a more nuanced understanding of how changing family roles and responsibilities can enhance overall family well-being.

Companionship goals and marital goal concordance contribute to relationship satisfaction partly through dyadic coping in dating couples.

BACKGROUND: Marital goals reflect individuals' understanding of the purpose of marriage and could influence the dyadic interactions and satisfaction in intimate relationships. The current study examines how each partner's marital goals and the concordance of marital goals between the partners influence dating couples' relationship satisfaction through dyadic coping. METHOD: The sample consisted of 200 heterosexual dating couples from Hong Kong. Both partners completed a survey that assessed three types of marital goals, dyadic coping, relationship satisfaction, and other background variables. Path analysis was conducted to estimate the Actor-Partner Interdependence Model (APIM) with each partner's three types of marital goals and marital goal concordance between the two partners as the predictors, each partner's dyadic coping as the mediators, and each partner's relationship satisfaction as the outcomes. RESULTS: Women's dyadic coping significantly mediated the effects of women's companionship goals and marital goal concordance on both partners' marital satisfaction. Meanwhile, men's dyadic coping significantly mediated the effects of men's companionship goals and marital goal concordance on their own relationship satisfaction. CONCLUSION: The current study offered the first evidence supporting the importance of marital goals, the goal concordance between the partners, and dyadic coping in dating relationships.

Impulsive Decision-Making, Affective Experiences, and Parental History of Self-Injurious Thoughts and Behaviors within Parent-Adolescent Dyads.

Impulsive decision-making, particularly during states of affective intensity, is associated with greater risk of engagement in self-injurious thoughts and behaviors (SITBs) during adolescence. The proximal (dyadic parent-adolescent affect and impulsivity) and distal (family history of SITBs) risk factors that occur within the family system could be relevant processes at stake in the intergenerational transmission of risk. The current study tests the interdependence of parent-adolescent factors associated with risk for SITBs and probes the extent to which parent-adolescent affective states influence their own (actor-effects) and each other's (partner-effects) impulsive decision-making, and further whether these relationships are moderated by a parent's history of SITBs. Participants included 212 (106 dyads) community parents and their adolescents who completed self-report and behavioral tasks related to positive and negative affective states, impulsive decision-making, and lifetime history of SITBs. Application of the Actor-Partner Interdependence Model (APIM) revealed a partner-effect where greater parent negative affect in the past week was associated with elevated adolescent impulsive decision-making among families with a history of SITBs (Estimate = 0.66, Standard Error = 0.13, p < 0.001). In addition, a significant actor-effect was observed where greater positive affect was associated with decreased impulsive decision-making among adolescents (Estimate = -0.21, Standard Error = 0.10, p = 0.03), however, moderating effects of parent history of SITBs were not detected. Findings from the present study shed light on the interdependence of affect and impulsivity within parent-adolescent dyads, and the extent to which these interactions may be particularly salient for families with known vulnerabilities for SITBs.

The Longitudinal Dyadic Associations Between Social Participation and Cognitive Function in Older Chinese Couples.

OBJECTIVES: Based on the "linked lives" tenant of the life course perspective, this longitudinal study aims to examine the actor and partner effects of social participation on cognitive function in older Chinese couples. METHODS: A total of 1,706 couples aged 60 and older were included in the final analyses. Social participation was measured using 2 questions regarding types of activities and frequency. Cognitive function was measured using a combination of memory, orientation, visuoconstruction, attention, and calculation. The lagged-dependent APIM was used to model the dyadic associations between social participation and cognitive function. RESULTS: The time-averaged actor effects of both husbands' and wives' social participation on their own cognitive function were significant (p < .001 for both). The time-averaged partner effect of husbands' social participation on wives' cognitive function was significant (p < .001) but the reverse-the effect of wives' social participation on husbands' cognitive function-was not (p = .381). The time-specific actor and partner effects were not significant (p > .05 for all). DISCUSSION: Our findings indicate an asymmetrical pattern of actor-partner interdependence, where husbands' social participation may affect their wives' cognitive function on average, but wives' social participation does not affect their husbands' cognitive function. Clinical practitioners should invite both partners, especially husbands, to participate in social participation interventions to facilitate crossover benefits for wives. Moreover, policymakers should build more facilities to encourage older couples to engage in social activities to prevent cognitive decline.

A dyadic perspective on parent-child dyadic coping in children with a chronic condition.

OBJECTIVE: In this study, we examined the extent to which parents and their children with a chronic condition communicate their stress to one another and whether stress communication is associated with different forms of dyadic coping. METHODS: In a sample of 239 parent-child dyads, self-reported stress communication and different forms of perceived dyadic coping (i.e., emotion-oriented, problem-oriented, and negative dyadic coping) were assessed using a cross-sectional design. RESULTS: We first found that children's stress communication was positively associated with more positive (r = 0.28, p < .001) and less negative dyadic coping responses by children (r = -0.22, p < .001). Children's stress communication was also associated with more positive (r = 0.52, r = 0.45, p's < 0.001), and less negative dyadic coping responses by parents (r = -0.19, p < .001). Using dyadic data of children with a chronic condition and their parents, we found that more stress communication of children was associated with healthier coping responses of both children (perceived emotion-oriented dyadic coping: ß = 0.23, p < .001) and parents (perceived emotion-oriented dyadic coping: ß = 0.33, p < .001; perceived problem-oriented dyadic coping: ß = 0.22, p < .001). CONCLUSION: This underscores the importance of communication and adaptive coping strategies of parents and children in the context of a child's chronic condition. These findings may help us find ways to support children and their parents to optimally communicate about and deal with their stress.

Associations between dyadic communication and dyadic coping of patients with cervical cancer and their spouses: a study utilizing the actor-partner interdependence model.

There is a growing focus on exploring dyadic interactions and outcomes between couples undergoing cervical cancer (CC). The purpose of this cross-sectional study was to figure out how dyadic communication influences both CC patients' and spouses' coping abilities. A sample of 286 CC dyads completed questionnaires assessing dyadic communication and dyadic coping. The actor-partner interdependence model was used to analyze the interaction effect between the dyads. Dyadic communication among cervical cancer (CC) patients has a predictive effect on their own negative dyadic coping (ß = - 0.141, P = 0.034) and on their spouses' delegated dyadic coping (ß = 0.133, P = 0.044). In contrast, dyadic communication among CC spouses is negatively associated with their own supportive dyadic coping (ß = - 0.237, P < 0.001), delegated dyadic coping (ß = - 0.156, P = 0.018), common dyadic coping (ß = - 0.148, P = 0.026) and also with CC patients' supportive dyadic coping (ß = - 0.153, P = 0.022). Dyadic communication between CC patients and their spouses affect their own and each other's dyadic coping. Exploring interventions focused on the CC couples' communication strategies to enhance their positive dyadic coping should be considered.

Dyadic effects of stigma on quality of life in people with schizophrenia and their family caregivers: Mediating role of patients' perception of caregivers' expressed emotion.

Schizophrenia, as a stressful diagnosis, profoundly impacts the whole family, especially people with schizophrenia and their caregivers. This study tested the potential mediating role of expressed emotion in the association between mental health stigma and quality of life in caregiver-patient dyads. Using a 2-wave longitudinal design with a 6-month interval between assessments, 161 dyads of patients with schizophrenia and their family caregivers (one patient and one caregiver) completed measures of mental health stigma, expressed emotion, and quality of life. The results showed that patients' self-stigma had no significant actor or partner effect on expressed emotion or quality of life. In contrast, caregivers' stigmatizing attitudes toward patients had a significant partner effect on patients' perception of caregivers' expressed emotion and quality of life. The mediating effect of patients' perception of caregivers' expressed emotion in the association between caregivers' stigmatizing ideas toward patients and patients' quality of life was significant. By focusing on the interdependence of patients and their caregivers, this study highlights the role of caregivers' stigmatizing attitudes toward patients and patients' perception of caregivers' expressed emotion on patients' quality of life. Psychoeducation and interventions should not only aim to reduce the self-stigma of people with schizophrenia but also their caregivers' stigmatizing ideas toward patients. Family interventions targeted at reducing the EE level of caregivers and patients' perception of caregivers' EE would also benefit the adaptation and quality of life of people with schizophrenia and their caregivers.

Depression Negatively Impacts Dyadic Quality of Life Following Neuro-ICU Admission: A Prospective Study of Cognitively Intact Patients and Caregivers.

BACKGROUND: Admission to a neurological intensive care unit (Neuro-ICU) can increase risk for depressive and anxiety symptoms for both patients and caregivers. To better understand the long-term mental health impact of a Neuro-ICU admission, we examined the dyadic interdependence between depression and anxiety at Neuro-ICU admission with 3-month quality of life (QoL) for patients and caregivers in a longitudinal, observational cohort study. METHOD: We assessed depressive and anxiety symptoms (Hospital Anxiety and Depression Scale; HADS) reported by neurologically intact patients (n = 72) and their caregivers (n = 72) within 2 weeks of Neuro-ICU admission (baseline) and 3-months post-discharge (follow-up). We examined the longitudinal association between dyadic depression and anxiety at Neuro-ICU admission and 3-month QoL (World Health Organization; QOL-BREF) across four domains (Physical, Psychological, Social relationships, and Environmental QoL) in separate actor-partner interdependence models (APIM) for patients and caregivers. RESULTS: In the overall models, patients' own baseline depression levels were negatively associated with their own 3-month QoL in all domains (ß = - 0.53 to - 0.64, p < 0.001), and for caregivers, only in the psychological (ß = - 0.73, p < .001) and social relationships (ß = - 0.56, p < .001) domains. No actor effects were found for one's own baseline anxiety impacting one's own 3-month QoL. Partner effects for one's own depression were significant for caregivers on patients' 3-month psychological (ß = - 0.26, p < .02) and environmental (ß = - 0.29, p < .03) QoL, as well as for patients on caregiver's 3-month psychological QoL (ß = 0.25, p < .02). No partner effects were significant in association with baseline anxiety and 3-month QoL in both patients and caregivers. CONCLUSION: Neuro-ICU patients' and caregivers' baseline depression has significant negative impacts on their own long-term QoL. Caregivers demonstrate significant negative impacts on patient long-term QoL in domains related to emotional distress and caregiver burden. Early identification of mental health symptoms, especially depression, during Neuro-ICU admission may provide an intervention opportunity to improve QoL post-discharge for both dyad members.

Self- reported and informal caregiver proxy-reported met needs in persons living with dementia are associated with lower health-related quality of life: a dyadic, cross-sectional study.

OBJECTIVE: This study examined the dyadic association of self and informal caregiver proxy-reported met needs in persons living with dementia on the health-related quality of life (HRQOL). METHODS: A total of 237 persons with dementia and their caregivers were included from a previous observational study. HRQOL was assessed by the EuroQol-5D and the number of met needs by the Camberwell Assessment of Needs for the Elderly. The Actor-Partner Interdependence Model framework was used to analyze the effect of an individual's self or proxy-reported met needs on their own HRQOL (actor effects), and an individual's self or proxy-reported met needs on the other dyad member's HRQOL (partner effects). RESULTS: The number of self-reported met needs by persons living with dementia was negatively associated with their own HRQOL (actor effect b = -0.200, p < 0.001), and the HRQOL of informal caregivers (partner effect b = -0.114, p = 0.001). The number of proxy-reported met needs by informal caregivers was negatively associated with their own HRQOL (actor effect b = -0.105, p < 0.001) but not the person living with dementia's HRQOL (-0.025, p = 0.375). CONCLUSION: Study findings suggest that both self-reported and informal caregiver proxy-reported met needs in persons living with dementia should be considered in research and practice because they have different implications for each dyad members' HRQOL.

Post-traumatic stress and health-related quality of life after admission to paediatric intensive care: Longitudinal associations in mother-child dyads.

OBJECTIVE: Elevated post-traumatic stress symptoms (PTSS) and reduced health-related quality of life (HRQoL) are commonly experienced in both children and their parent's following admission to the paediatric intensive care unit (PICU). Previous research has demonstrated a conflict in the directionality between PTSS and HRQoL in children and their parents. Our study sought to explore the interconnection and transmission between PTSS and HRQoL in children and their mothers following an admission to the PICU. DESIGN: Prospective longitudinal design. SETTING: Two tertiary care PICUs in Brisbane, Australia. PATIENTS: Two hundred eighty-two mother-child dyads of children aged 2-16 years admitted to the PICU for >8 h. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: Four waves of dyadic data (n = 282 mother-child dyads) over a 12-month period from the PICU post-traumatic stress study were used. Cross-lagged panel modelling was used to examine the link between maternal-rated PTSS and HRQoL across children and their mothers. Actor-partner interdependence modelling was then used to examine the interconnections between mothers and children over time. In the dyadic model, partner effects were only present from mother to their child (i.e., higher maternal PTSS was predictive of higher child PTSS at subsequent time points). Higher maternal PTSS predicted lower maternal mental HRQoL but not lower child psychosocial HRQoL. Actor effects were also present with lower child psychosocial HRQoL, predicting higher child PTSS at subsequent time points. Findings indicated that a unidirectional transmission process from mother to child may be present after a child's life-threatening illness. CONCLUSIONS: This study provides evidence for a long-term negative influence of maternal PTSS on child PTSS in families who have experienced a paediatric critical illness or injury. This highlights the important role of maternal wellbeing in children's mental health outcomes following PICU admission. Further research needs to explore the temporal and dyadic relationships of PTSS and HRQoL.
