Training interoceptive sensitivity (IS) might be a first step in effectively promoting intuitive eating (IE). A dyadic interoception-based pilot randomized controlled trial was conducted to increase IE among couples aged 50+. The training consisted of three exercises, a Body Scan (BS), a hunger exercise (HU), and a satiety (SA) exercise. This study explored how spouses accepted the (dyadic vs. single) training. In a mixed-methods convergence design, the findings of a survey (n = 68 couples) and focus groups (n = 4) were synthesized. Moderate general acceptance (e.g., regarding feasibility and low burden) and a hierarchical gradient in favor of the BS (e.g., pleasantness and improved sleep quality) emerged. Barriers concerned a perceived lack of the exercises\' usefulness and a limited understanding of the training purpose. A wish for regular feedback and exchange with the study stuff and other participants was expressed. Spousal training involvement was experienced as being rather beneficial. Previously harmonized dietary practices and daily routines appeared as constructive pre-conditions for the joint training. This study highlights the potential and implications of training couples in IS. Future interventions should involve a regular exchange and closer guidance by study staff to promote a better understanding of the processes and goals of IS and IE.

OBJECTIVE: To evaluate the clinical effects of a couple-focused dyadic coping intervention in colorectal cancer (CRC) couples.
METHODS: The study was a single-blinded randomized controlled study which 226 CRC couples were recruited and randomized to either the intervention (N = 113) or the control (N = 113) group. All couples received usual care while the six-week dyadic coping intervention was provided to the intervened couples in psycho-education and skill training methods through face-to-face combined with telephone formats. Measurement data, including dyadic coping, marital satisfaction, quality of life and psychological well-being were collected at pre- and post-intervention periods. And multilevel model (MLM) was applied to analyze the effects of the intervention and the role tendency.
RESULTS: A total of 173 couples completed the program and post-intervention evaluation. The retention rate was 76.5%. Results from MLM showed that the dyadic coping intervention is effective in promoting levels of dyadic coping (P < 0.001), marital satisfaction (P = 0.042), mental health (P = 0.006), and positive psychological well-being (P < 0.001), and alleviating depression (P = 0.015) in CRC couples. For role tendency, the intervention found to be more effective in CRC spousal caregivers\' positive psychological well-being compared to the patients (P = 0.037).
CONCLUSIONS: The couple-based dyadic coping intervention is effective in promoting dyadic coping and improving psychological adjustment in CRC couples. More studies were needed to further evaluate the program and its long-term efficacy in the future. In addition, given the positive effects of the intervention, clinical nursing stuffs may consider implementing such intervention in their routine work while caring for CRC couples.

Most people with dementia live at home and depend on informal caregivers for care. Both caregivers and persons with dementia can experience negative psychological and behavioural effects as the disease progresses. Non-pharmacological interventions can alleviate these effects and dyadic interventions, involving both caregiver and person with dementia, may be particularly effective. In this systematic review, the effect of dyadic interventions involving community-dwelling persons with dementia and their informal caregivers was researched. This article is an update of a review of dyadic interventions up to 2012 (Van\'t Leven et al., 2013). Twenty-two randomized controlled trials published between January 2012 and March 2023 met eligibility criteria, representing 3857 dyads. Results of a meta-analysis showed no overall intervention effect. Thirteen studies reported positive intervention effects, 9 studies reported no intervention effects. Intervention content and participant characteristics and knowledge of the disease varied widely between the studies reviewed. Effective interventions were those that matched activities for the person with dementia to their interests and abilities and educating the caregiver about dementia and communication. Interventions of moderate length (3-4 months) tended to be more effective than longer or shorter interventions. Future studies should further explore the factors contributing to the effects of dyadic interventions.

There are a growing number of early-phase (i.e., Stage I, NIH Stage Model) interventions targeted at family care dyads navigating chronic health conditions in older adults. Currently, the benefits of these interventions are often evaluated for older adults and their family care partners separately, even when controlling for interdependence. Without understanding the benefits (and potential harms) for dyads as a whole, understanding of program impact is incomplete. Moreover, few health behavior interventions involving dyads include relational measures to ensure no unintended consequences for the dyad or account for within-dyad pretest risk level.
We used secondary data from a quasi-experimental trial involving 39 couples in which 1 member of the dyad was living with Parkinson\'s disease as an exemplar demonstration of 3 proposed approaches: an above-zero approach, a pretest risk status approach, and an expanded pattern analysis matrix approach.
Approaches provided evidence for dyadic benefits of the intervention compared to the wait-list comparison condition, but carried different assumptions that did not always categorize dyads similarly.
Implications of using each approach and selecting different benchmarks for defining success are discussed. The descriptive approaches proposed, provide a rationale for more intentional evaluation of small-sample, early-phase dyadic interventions.

OBJECTIVE: To investigate the effects of dyadic intervention on anxiety, depression, care burden and quality of life in informal caregivers of palliative patients with lung cancer.
BACKGROUND: Informal caregivers of palliative lung cancer patients bear a large number of negative emotions during the process of caring for the patients. Dyadic intervention has the potential for improving them but the overall effect is unclear.
METHODS: A systematic review and meta-analysis.
METHODS: All randomized controlled trials were retrieved from the following databases until 4 May 2023: Web of Science, Embase Ovid, PubMed, Cochrane Central Register of Randomized Controlled Trials, Weipu, Wanfang and Chinese National Knowledge Infrastructure databases.
METHODS: This review was performed by Stata 12.0 and Review Manager 5.3.
RESULTS: Thirteen randomized controlled trials were in accordance with the inclusion and exclusion criteria (n = 1807). The results revealed that dyadic intervention significantly improved family caregivers\' anxiety, depression and caregiver burden of palliative patients with lung cancer. There was no significant difference in quality of life between the dyadic intervention group and family caregivers who did not receive the dyadic intervention.
CONCLUSIONS: Dyadic intervention positively impacts the experience of family caregivers of palliative patients with lung cancer.

Evidence on the effectiveness of cooking activities as a well-being promotion intervention for older adults with subjective cognitive decline (SCD) and their caregivers is scarce. In view of this, a randomized controlled trial was conducted to examine whether a dyadic cooking-based intervention can improve the subjective health and well-being of older adults with SCD and their caregivers, as well as the cooking competence of the former group.
Randomized controlled trial.
Community.
Sixty pairs of community-dwelling older adults aged 60 years or above with SCD (mean age = 78.4 years) and their caregivers (mean age = 65.3 years) were randomly assigned to the intervention group (N = 30 pairs) and the wait-list control group (N = 30 pairs).
The intervention was an innovative 5-week (two hours per week) dyadic cooking-based intervention employing procedural learning methods specifically adapted for older adults with SCD.
The outcome measures included 1) a well-being index composed by four indicators: life satisfaction, feeling of happiness, sense of purpose and meaning in life, and perceived health, and 2) cooking competence.
For both older adults with SCD and their caregivers, the increases in the well-being index were significantly greater in the intervention group than in the control group (β = 0.508, 95% CI [0.036, 0.980]). For older adults with SCD, the increases in the cooking competence score were significantly greater in the intervention group than in the control group (β = 1.629, 95% CI [0.165, 3.071]).
The dyadic cooking-based intervention resulted in improvements in the cooking competence and well-being of older adults with SCD, as well as the well-being of caregivers.

OBJECTIVE: Dyadic interventions, involving two persons with a preexisting close relationship, offer the opportunity to activate support persons (SPs) to improve health for adults with chronic conditions. Requiring SP coparticipation can challenge recruitment and bias samples; however, the associations between voluntary SP coparticipation and recruitment outcomes across patient characteristics are unknown.
METHODS: The Family/Friend Activation to Motivate Self-care 2.0 randomized controlled trial (RCT) enrolled adults with Type 2 diabetes (T2D) from an academic health system. Participants were asked-but not required-to invite an SP to coenroll. Using data from the electronic health record we sought to describe RCT enrollment in the setting of voluntary SP coparticipation.
RESULTS: In a diverse sample of adults with (T2D) (48% female, 44% minoritized race/ethnicity), most participants (91%) invited SPs and (89%) enrolled with SPs. However, prerandomization withdrawal was significantly higher among participants who did not have consenting SPs than those who did. Females were less likely to invite SPs than males and more Black PWD were prerandomization withdrawals than randomized.
CONCLUSIONS: Voluntary SP coenrollment may benefit recruitment for dyadic sampling; however, more research is needed to understand if these methods systematically bias sampling and to prevent these unintended biases.

UNASSIGNED: Hispanic/Latina girls have a low prevalence of moderate-intensity physical activity (PA) compared to their male counterparts and non-Hispanic White girls. Mothers influence their children\'s activity levels by creating and supporting PA opportunities, modeling PA, and reinforcing children\'s efforts to be physically active. The Conmigo trial will evaluate a mother-daughter intervention to promote PA and examine potential mechanisms of change including mothers\' PA, parenting regarding PA, and mother-daughter communication.
UNASSIGNED: This randomized controlled trial examines the feasibility, acceptability, and impact of a 12-week intervention promoting PA in preadolescent Latina girls in San Diego County, CA. Participants (n = 90 dyads) are randomized to the Conmigo PA intervention or to a control group that receive an abbreviated version of the intervention. The intervention was informed by Social Cognitive Theory and Family Systems Theory and emphasize family-level factors to promote PA using an actor-partner model. Mothers and daughters attend weekly 90-min sessions in English or in Spanish via Zoom video conferencing, supported by facilitator follow-ups and WhatsApp supportive chat group for mothers. Objective (accelerometer) and self-report measures at baseline, 3 months, and 6 months capture the frequency and intensity of PA and correlates and predictors of PA. We also examine the impact of the intervention on the bidirectional influence of mother-daughter PA.
UNASSIGNED: The findings from the Conmigo trial will form the basis of a randomized controlled community trial and will move the field forward in identifying targets of change in preventing chronic disease risk in Hispanic/Latino communities.

BACKGROUND: Stroke can cause a variety of physical and psychosocial disturbances for both survivors and their family caregivers (i.e., stroke dyads). Dyadic psychoeducation appears to be a promising approach for providing knowledge of stroke and self-care or caregiving skills to improve stroke dyads\' health outcomes. Therefore, a family-focused psychoeducation intervention was designed and tested to improve the health outcomes of stroke dyads.
OBJECTIVE: To examine the effects of a family-focused dyadic psychoeducational intervention on the functional and psychosocial outcomes of stroke survivors and family caregivers.
METHODS: A single-blinded, parallel-group randomised controlled trial with repeated-measures design.
METHODS: Two general hospitals and one rehabilitation facility in Jinan, China.
METHODS: Stroke survivors and family caregivers (N = 162 dyads).
METHODS: The dyads were randomly allocated to either psychoeducation or control group with usual care only (N = 81 dyads per group). The intervention included three structured face-to-face education sessions (one hour per session) in hospital pre-discharge and four weekly telephone counselling calls post-discharge. Study outcomes included survivor functioning and caregiver burden (primary outcomes), and other secondary outcomes (i.e., caregiving competence, dyads\' coping, depressive and anxiety symptoms, family functioning, and dyadic relationship, as well as survivor healthcare utilisation and caregiving-related injury). Data were collected at baseline (T0) and immediately (T1) and 3 months post-intervention (T2). The intervention effects were estimated using generalised estimating equation models.
RESULTS: Participants in the psychoeducation group revealed significantly greater reductions on caregiver burden than the control group at T1 (β = -6.01, p = 0.026) and T2 (β = -6.73, p = 0.039), but non-significant effects on survivor functioning, except in emotion domain at T1 (β = 7.22, p = 0.015). In addition, the intervention demonstrated significantly greater improvements on caregiving competence (β = 0.98, p = 0.013; β = 1.58, p < 0.001), survivors\' depressive symptoms (β = -1.56, p = 0.007; β = -2.06, p = 0.005), and dyadic relationship (β = 0.26, p = 0.012; β = 0.27, p = 0.022) at T1 and T2, as well as on survivor coping at T2 (β = 6.73, p = 0.008).
CONCLUSIONS: Our study added values on the benefits of family-focused dyadic psychoeducation to routine stroke rehabilitation and family care. Future research can evaluate its long-term effects for families of stroke survivors with diverse socio-demographic and stroke-related characteristics.
BACKGROUND: Chinese Clinical Trial Registry (ChiCTR2100042684). Recruitment: March to June 2021.

UNASSIGNED: Cancer-related fatigue is one of the most common adverse reactions to cancer survivors, which has a significant impact on the daily life. As a traumatic event, cancer not only brings great physical and mental harm to patients, but also poses a threat to the physical and psychological health of caregivers. Current studies have shown that physical activity improves cancer-related fatigue in cancer survivors. And studies have suggested that dyadic interventions are more effective in improving patient outcomes and may also provide some benefits to caregivers. But the literature on the effects of dyadic-based physical activity on improving cancer-related fatigue has not been synthesized. This scoping review described the scope and impact of studies on cancer-related fatigue with dyadic-based physical activity interventions.
UNASSIGNED: Six databases which is PubMed, Cochrane Library, Web of Science, Embase, CINAHL and Medline were searched for all studies of dyadic-based physical activity interventions with outcome measures including cancer-related fatigue published since the inception of the databases through May 2022. The search strategy was developed based on PICO principles.
UNASSIGNED: This article includes 6 pre and post-test designs and 2 randomized controlled trial design. The majority of participants were survivors with breast and lung cancer. The overall results showed that the effectiveness of dyadic-based physical activity interventions in improving cancer-related fatigue was unsatisfactory.
UNASSIGNED: This scoping review suggests that current dyadic-based physical activity interventions are not well-researched among cancer survivors. In the future, more high-quality studies with more sophisticated and rigorous interventions are needed.
