Objective: This study was designed to investigate the effects of individual, dyadic, and collaborative planning on moderate-to-vigorous physical activity (MVPA; primary outcome) and energy-dense food intake (secondary outcome) in dyads of parents and their 9-15-year-old children. Individual planning reflects an "I-for-me" planning of one person's behavior. Collaborative ("we-for-us") planning refers to joint planning of both dyad members' behavior, whereas dyadic ("we-for-me") planning involves joint planning of only the target person's behavior.

Method: N = 247 dyads participated in a randomized controlled trial with individual, dyadic, or collaborative physical activity (PA) planning and control conditions (education about PA, sedentary behavior, nutrition, energy intake-expenditure balance). MVPA was measured with ActiGraph wGT3X-BT accelerometers at baseline, 1-week, and 36-week follow-ups. Energy-dense food intake was self-reported at baseline, 9-week, and 36-week follow-ups. Linear mixed models were fit for parents and children separately.

Results: At the 36-week follow-up, children in the dyadic "we-for-me" planning condition decreased their MVPA compared to the control condition. At the same time, children in the dyadic planning condition also decreased energy-dense food intake at the 36-week follow-up. No effects were found among children in individual and collaborative PA planning conditions. Parents in any experimental conditions decreased energy-dense food intake.

Conclusions: Children's decrease in MVPA in dyadic PA planning condition was offset by a reduction of energy intake, which may represent a compensatory mechanism. The limited effectiveness of the dyadic "we-for-me" interventions in parent-child dyads may result from young people's needs for individuation and their reactance to parental support.

Objective: Psychological distress in cancer survivors may be partially attributable to fear of cancer recurrence (FCR). Simonelli et al. (2017) proposed a conceptual model of FCR, which suggests that cancer cues (e.g., physical symptoms) may prompt maladaptive emotional processing leading to heightened FCR, and thus increased psychological distress. This prospective study tested this model by examining the cascading pathways by which physical symptom burden, emotion dysregulation, and FCR were associated with posttraumatic stress symptoms (PTSS) and anxiety among recently diagnosed cancer survivors.

Method: Psychosocial and well-being data from 486 breast (63.7%), prostate (25.7%), and colorectal (10.7%) cancer survivors (M_age = 58.7 years; 31% male) were collected over 12 months as they transitioned off primary treatment into early survivorship. A path analysis was performed to examine whether physical symptom burden led to more emotion dysregulation and elevated FCR and, in turn, more psychological distress (PTSS and anxiety).

Results: Greater physical symptom burden at Time 1 was associated with more emotion dysregulation at Time 2, which was related to heightened FCR at Time 3 and, in turn, more psychological distress at Time 4. Additionally, the indirect effect of physical symptom burden on FCR through emotion dysregulation and the indirect effects of emotion dysregulation on PTSS and anxiety through FCR were also significant.

Conclusions: The findings support Simonelli et al.'s (2017) conceptual model of FCR and distress and highlight the importance of assessing and addressing physical symptom burden and improving emotional processing abilities to help mitigate heightened psychological distress among cancer survivors.

Cancer poses significant challenges for patients and caregiving partners. Avoidant communication has been linked to poorer psychosocial adjustment to cancer. Two conceptual models have been proposed to account for this linkage: the social-cognitive processing and relationship intimacy models.

Objective: To examine the utility of these models in explaining patient and partner psychological and relationship adjustment on a day-to-day basis using ecological momentary assessment.

Method: Patients with breast, colorectal, or lung cancer and their partners (286 dyads) were prompted twice daily for 14 days via smartphone to answer questions about communication with their partner, adjustment (psychological distress and relationship satisfaction), and hypothesized mediators (avoidant thoughts and intimacy). Data were collected from 2017 to 2020.

Results: Participants responded to 92% of prompts and completed 91%. Results supported the relationship intimacy but not the social-cognitive processing model. On afternoons when participants (both patients and caregivers) held back or perceived avoidance or criticism from their partner, they reported less intimacy, as did their partners; this lowered intimacy, in turn, led to participants' (both patients' and caregivers') own lowered relationship satisfaction that evening and to patients' lowered relationship satisfaction through caregivers' lowered intimacy (one-tailed Bayesian ps < .025). When distress was the criterion, patients' holding back or perceived avoidance/criticism led to their own increased distress through their own decreased intimacy, and caregivers' holding back or perceived avoidance/criticism led to patients' increased distress through patients' lowered intimacy (one-tailed Bayesian ps < .005).

Conclusions: Findings offer implications for interventions designed to improve communication and enhance closeness. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Obesity is one of the most prominent health issues in modern society. Although previous research has identified chronic psychological stress as a risk factor for obesity, much of this research only examined how an individual's own stress affects their adiposity. The current study utilized an actor-partner interdependence model to examine the unique associations of youths' and parents' chronic stress with both their own and each other's adiposity.

Method: Five hundred sixty-nine dyads of youths (48.7% females, 49.9% Whites, M_age = 13.70 years) and one of their parents (82.6% females, 58.2% Whites, M_age = 45.38 years) participated in a cross-sectional lab study, where both youths and parents completed interviews and anthropometric measurements. Trained interviewers conducted the UCLA Life Stress Interview to assess chronic psychological stress of youths and parents, respectively. Youth and parent adiposity was measured using three indicators, including body mass index, waist circumference, and body fat percentage.

Results: The actor-partner interdependence model showed that when both youths' and parents' chronic stress were included simultaneously in the model, youths' chronic stress was uniquely associated with both their own and their parents' adiposity, and parents' chronic stress was also uniquely associated with youths' adiposity.

Conclusion: Chronic psychological stress of youths and parents is uniquely associated with each other's adiposity, over and above their own stress. Thus, the psychosocial experiences of close others can be linked to both youth and adult obesity. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Despite the proven benefits of vaccination, people differ in their willingness to get vaccinated. These differences are the result of multiple factors, including social, cultural, and psychological variables. This meta-analysis estimated the effects of people's Big Five personality traits on their vaccination attitudes, intentions, and behaviors and examined the role of theoretically and empirically derived moderator variables.

Method: We meta-analyzed data from 28 studies that sampled over 48,000 individuals to estimate the effects of Big Five personality traits on vaccination attitudes, intentions, and behaviors. In addition, we tested the moderating effects of age, gender, sample region, sample type (representative vs. convenience), vaccination measure (attitude, intention, behavior, compound), vaccination type (COVID-19, Influenza, or other), and reliability of the Big Five measure on the links between personality traits and vaccination.

Results: People with high levels in agreeableness and extraversion, and low levels in neuroticism reported more positive attitudes toward vaccination, whereas open people reported stronger intentions to get vaccinated. Open and agreeable people were also more positive about novel COVID-19 vaccines, whereas extraverted people were more positive about influenza vaccines. There were no effects for conscientiousness. Overall, effect sizes were small but generalized across age. Other moderator effects suggested a more nuanced picture across cultural regions, sample types, and gender.

Conclusions: The findings provide a compelling picture of significant, albeit small, effects of personality traits on vaccination. Questions remain about the processes through which personality traits may affect vaccination attitudes, intentions, and potentially also behavior.

Objective: Eating in response to stress can become habitual and have long-term consequences for weight gain, but little research has explored what may help break stress-eating cycles. We examined daily social resources as potential protective factors against daily stress eating and eventual weight gain.

Method: In Study 1 (N = 1,264), we assessed stress-eating tendencies, body mass index (BMI) and waist-to-hip ratio (WHR) at baseline, receipt of emotional support over 8 days (9,649 reports), and tracked BMI/WHR after about 10 years. We examined the average likelihood of receiving emotional support as a moderator of the link between stress eating and BMI/WHR at the follow-up. In Study 2 (N = 536; 10,288 reports), we assessed stress-eating status and BMI at baseline, social responsiveness (feeling that others are caring), and stress-eating behavior over 24 days and tracked BMI a year later. We examined if social responsiveness moderates stress-eaters' daily stress-eating behaviors and changes in BMI.

Results: In Study 1, stress eating predicted increases in BMI and WHR at the 10-year follow-up but not among individuals who were more (vs. less) likely to receive emotional support in daily life. In Study 2, stress eaters tended to report more daily stress-eating behaviors compared to nonstress eaters, but such tendency was attenuated on days they perceived high (vs. low) levels of social responsiveness. Stress eating did not predict BMI at the 1-year follow-up.

Conclusions: These observational findings suggest that social resources in daily lives may have long-term benefits for stress eaters, potentially by reducing their everyday stress eating. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Despite the popularity of mindfulness in research and interventions, information is missing about how and why mindfulness may benefit employee sleep health. Drawing from emotion regulation theory, we evaluate affective rumination, negative affect, and positive affect as potential mechanisms. We also explore differential effects of trait and state attentional mindfulness on both subjective (e.g., quality and sufficiency) and actigraphy-measured aspects (e.g., duration and wake after sleep onset) of sleep health.

Method: Ecological momentary assessment and sleep actigraphy data were collected across two independent samples of health care workers (N1 = 60, N2 = 84). Ecological momentary assessment was also used to collect daily information on state mindfulness, affect, and rumination.

Results: Our results support rumination and, to a less consistent extent, negative affect as mediators of the association between mindfulness and sleep health but not positive affect. Trait and state mindfulness demonstrate comparable benefits for employee sleep health, but these benefits largely emerge for subjective sleep dimensions than actigraphy-measured.

Conclusions: These findings support emotion regulation as a sound theoretical framework for sleep and mindfulness research and may support more informed workplace mindfulness interventions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objectives: To examine the prospective association between perceived everyday discrimination and Type 2 diabetes incidence in a large population-based sample.

Method: Data were from the Health and Retirement Study of 14,900 individuals aged ≥ 50 years without a diabetes diagnosis. Participants self-reported experiences of everyday discrimination and diabetes status. Associations between baseline perceived everyday discrimination (one time point) and incident diabetes in the following 10 years were modeled using Cox regression, adjusting for potential confounders. Exploratory analyses assessed the association between repeated reports of perceived everyday discrimination (reports of everyday discrimination at more than one time point) and later diabetes onset.

Results: A total of 917 (6.15%) of the 14,900 participants developed Type 2 diabetes over a maximum 10-year follow-up (Mdn = 6). Baseline perceived everyday discrimination was prospectively associated with an increased risk of diabetes (hazard ratio = 1.37, 95% confidence interval [1.15, 1.63], p < .001) independent of age, sex, wealth, race and ethnicity, and education. This association was robust to further adjustment for body mass index, hypertension, physical activity, smoking, alcohol consumption, and depression. In exploratory analyses, repeated reports of everyday discrimination were not significantly associated with incident diabetes.

Conclusions: Individuals who perceive everyday discrimination are more likely to develop Type 2 diabetes than those who do not perceive everyday discrimination. Further research is needed to investigate the potential pathways linking discrimination and diabetes onset. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Most work on place-based (e.g., rural-urban) health disparities has been conducted with population-level data, which is limited in its capacity for causal inferences about individuals and lifespan health. The present study leverages individual-level longitudinal data, spanning up to 29 years, to understand how rurality-urbanicity predicts risk for all-cause mortality; whether these associations hold above and beyond socioeconomic status (SES); and whether the association between rurality-urbanicity and mortality risk varies by sex, SES, race, ethnicity, and partner status.

Method: The present preregistered study uses data from two large longitudinal studies of U.S. Americans (Health and Retirement Study and Midlife in the United States; total N = ∼55,000), who reported on their sociodemographic characteristics, had their addresses linked to geographical indicators (i.e., rural-urban continuum codes), and have data from the National Death Index regarding the vital status and survival time.

Results: Using Cox proportional hazards regression models, findings showed that suburban and rural residents were at a 12% and 18% greater risk for earlier mortality compared to urban residents in Health and Retirement Study, but the associations between rurality-urbanicity and mortality risk were nonsignificant in Midlife in the United States. The longitudinal associations between rurality-urbanicity and mortality risk were largely independent of SES. Finally, there was only one statistically significant interaction effect, suggesting the strength and direction of the association between rurality-urbanicity and mortality risk was largely the same across sociodemographic subgroups.

Conclusions: There is tentative evidence suggesting that rurality-urbanicity is an important social determinant of longevity, over and above other sociodemographic factors. Future studies should explore how to promote longer and healthier lives among rural residents. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: The current study applied survival analysis to examine factors associated with nondisclosure of human immunodeficiency virus (HIV) serostatus among mothers living with HIV (MLH) who had participated in a cognitive-behavioral intervention to disclose their HIV status to their children.

Method: Data were utilized from MLH in the intervention arm of the teaching, raising, and communicating with kids (TRACK; Schulte et al., 2021) trial focusing on serostatus disclosure/nondisclosure across four time points (baseline, 3, 9, and 15 months). MLH (M_age = 39.4) resided in California or Georgia and identified as Latina (33%), Black (54%), White (5%), or multiracial (8%). Physical, mental health, and psychosocial measures from the 3-month assessment were used to predict nondisclosure applying Cox regression survival analysis.

Results: Nondisclosure was associated with MLH reporting better physical and mental health, less conflict with their child, better cohesion within their families, and less perceived stigma. MLH reporting better physical functioning were 58% less likely to disclose compared to those reporting physical limitations (hazard ratio [HR] = 0.42). Those reporting lower levels of disclosure self-efficacy were 59% less likely to disclose than those reporting higher levels (HR = 2.47); by 67 weeks into the study, the nondisclosure rate was 56% for those reporting lower self-efficacy compared to 24% for those reporting higher self-efficacy.

Conclusions: Addressing the inclination not to disclose when the MLH is feeling healthy may be an aspect to incorporate into future interventions. Furthermore, improving disclosure self-efficacy to a high level appears to be a critical component to intervention success. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
