Objective: Women dealing with breast cancer (BC) face many challenges, one of which is the fear of cancer recurrence (FCR). This study examined whether disease severity predicts FCR 6 months after cancer diagnosis through psychological distress and whether cognitive-emotion regulation moderates this effect.

Method: The study sample included 656 women from Italy (27.5%), Finland (31.9%), Israel (19.8%), and Portugal (20.8%) diagnosed with Stages I-III of BC. Participants' age ranged between 40 and 70 years (M = 54.92, SD = 8.22). Participants were tracked following BC diagnosis and at 3 and 6 months follow-up. Participants filled out self-report questionnaires, including the FCR inventory-short form, the Hospital Anxiety and Depression Scale, and the cognitive-emotion regulation questionnaire along with medical-social-demographic data.

Results: Greater disease severity at baseline indicated by higher cancer stage predicted greater psychological distress, which in turn predicted greater psychological distress at 3 months. The latter predicted greater FCR at 6 months. This serial mediation model was moderated by negative cognitive-emotion regulation. The mediating effect of disease severity on FCR through psychological distress was significant only in women with mean or higher levels of negative cognitive-emotion regulation.

Conclusion: This study suggests that facilitating psychological well-being and effective cognitive-emotion regulation in the early stages after a cancer diagnosis may protect women from FCR. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Childhood trauma may contribute to lifelong health through chronic systemic inflammation. However, associations between childhood trauma and inflammation are mixed, indicating that distinct types of childhood trauma may relate to inflammation differently. Moreover, most studies use a single assessment of inflammatory markers that may not reliably estimate stable interindividual differences. The current study is the first to examine relationships between childhood trauma and an ecologically valid measure of inflammation derived from repeated assessments of interleukin (IL)-6 in daily life. We also examine the possibility that glucocorticoid sensitivity and patterns of daily cortisol may contribute to observed associations. Finally, we explore whether biological sex moderates relationships between childhood trauma and IL-6.

Method: Participants were 283 healthy adults aged 40-64 (57% female, 23% Black, Indigenous, and People of Color) who completed the Childhood Trauma Questionnaire and self-collected dried blood spots at home on 4 days to measure IL-6. Measures of salivary cortisol and blood-based glucocorticoid sensitivity were also assessed.

Results: Childhood trauma was not associated with IL-6 in the sample as a whole. However, exploratory analyses showed that childhood trauma related to IL-6 differently for males and females, such that total trauma and emotional neglect predicted higher IL-6 for males but not females. Results persisted after adjustment for covariates. There was no evidence for indirect effects via cortisol or glucocorticoid sensitivity.

Conclusions: Childhood trauma and, specifically, emotional neglect were associated with IL-6 in daily life among middle-aged males. Additional research is needed to elucidate biological and behavioral pathways underlying these associations. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: To determine the day-to-day associations between minority stressors (i.e., anticipated and experienced discrimination) and sleep health outcomes (i.e., total sleep time (TST), sleep disturbances, and sleep-related impairment) among sexual and gender minority (SGM) people of color.

Method: An online sample of SGM people of color living in the United States participated in a 30-day daily diary study. Daily anticipated and experienced discrimination as well as subjective sleep outcomes were assessed via electronic diaries using validated measures. Wrist-worn actigraphy was used to objectively assess TST. Multilevel linear models (MLMs) were used to estimate the independent associations of daily intersectional minority stressors with subsequent sleep outcomes, adjusted for demographic factors and lifetime discrimination.

Results: The sample included 43 SGM people of color with a mean age of 27.0 years (± 7.7) of which 84% were Latinx, 47% were multiracial, and 37% were bisexual. Results of MLMs indicated that greater report of daily experienced discrimination was positively associated with same-night sleep disturbances, B (SE) = 0.45 (0.10), p < .001. Daily anticipated discrimination was positively associated with sleep-related impairment on the following day, B (SE) = 0.77 (0.17), p < .001. However, daily anticipated and experienced discrimination were not associated with same-night TST.

Conclusions: Findings highlight the importance of considering the differential effects of daily intersectional minority stressors on the sleep health of SGM people of color. Further research is needed to identify factors driving the link between daily minority stressors and sleep outcomes to inform sleep health interventions tailored to this population.

Objective: The goal of this article is to describe a conceptual multilevel model that provides evidence of embodiment of a societal stressor on the health of the individuals and illustrate with simulated data how omitting components in the analysis model fails to properly capture how context influences health.

Method: We describe a two-level model with variables at each level: stress at the group level and appraisal at the individual level. These factors are assumed to influence the blood pressure of individuals. Importantly, the person-level predictor is responsible for bringing the group-level predictor to the individual level by a cross-level interaction between stress and appraisal and/or a mediated effect of stress. When combined, the model components may be partitioned into a pure direct effect, a pure indirect effect, pure interaction effect, and an interaction-in-mediation effect. Data were generated in accordance with the model with each component accounting for some proportion of variance in blood pressure.

Results: To the extent these components operate in the process of embodiment, a proposition we argue is reasonable, failure to specify the analytic model with all components leads to failure to characterize embodiment and misattribution of the effect and mechanism.

Conclusions: To fully quantify embodiment of a societal stressor on a health outcome, studies should use multilevel designs and estimate cross-level interactions and mediated effects. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Purpose: This study aimed to examine the double-edged effect of social mobility belief on socioeconomically disadvantaged adolescents' mental and physical health and further explore whether intentional self-regulation is the common psychological mechanism of social mobility belief affecting physical and mental health.

Method: A total of 469 adolescents (M_age = 13.96 years, 49.3% boys) from two rural public schools in China were included in this study. Adolescents completed questionnaires measuring social mobility belief and mental health (life satisfaction, self-esteem, and depression). Physical health (allostatic load) was reflected by six indicators (resting diastolic and systolic blood pressure, body mass index, epinephrine, norepinephrine, and cortisol).

Results: Social mobility belief was positively correlated with adolescents' life satisfaction and self-esteem but negatively correlated with depression. Intentional self-regulation mediated the relationships between social mobility belief and mental health. In addition, the results showed that intentional self-regulation mediated the relationship between social mobility belief and adolescents' physical health.

Conclusions: Social mobility belief may be a "skin-deep" resilience resource positively related to mental health but negatively correlated with physical health through intentional self-regulation among socioeconomically disadvantaged adolescents.

Objectives: This study investigated the causal impact of sleep durations on participants' physical activity (PA) in real-world conditions.

Method: We performed a secondary analysis of PA data from 146 young adults using a randomized crossover design: both restricted (5-6 hr/night) and well-rested (8-9 hr/night) sleep weeks were assessed, with a washout week in between. Sleep and activity were tracked via research-grade actigraphy. Data analysis of PA involved repeated-measures analysis of variance (ANOVA) and regression techniques.

Results: Analysis plans and hypothesis were preregistered before data analysis. The exogenously assigned sleep restriction (SR) treatment reduced nightly sleep an average of 92.65 min (± 40.44 min) compared to one's well-rested sleep treatment. The impact of SR on PA was substantial, leading to a 7% reduction in average hourly PA: 18,081.2 (well-rested) versus 16,818.2 (restricted sleep). Significant findings were revealed in daily, F(1, 6) = 84.37, p < .001, η_p² = 0.934, and hourly comparisons, F(1, 166) = 30.47, p < .001, η_p² = 0.155. Further, sensitivity analysis using a variety of regression specifications also found that exogenously assigned SR decreased average wake-hour activity counts by approximately 4.4%-4.7% (p < .01 in all cases) when controlling for other factors. Exploratory analysis showed the PA effects of SR manifested via reductions in PA intensity with concurrent increases in the proportion of time considered as sedentary.

Conclusions: SR significantly lowered PA by around 7%, characterized by reduced intensity and elevated sedentary behavior in a naturalistic setting. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: The current study examined how average daily loneliness (between-persons [BPs]), intraindividual variability in loneliness across days (within-persons [WPs]), and loneliness stability informed physical health symptomatology.

Method: We utilized daily diary data from a national sample of 1,538 middle-aged adults (M_age = 51.02; 57.61% women) who completed eight end-of-day telephone interviews about daily experiences, including loneliness and physical health symptoms (e.g., headaches, nausea). Via multilevel modeling, we examined average daily loneliness (BPs), intraindividual variability in loneliness (WPs), stability in loneliness (individual mean-squared successive difference) in association with the number and average severity of daily physical health symptoms.

Results: When participants were less lonely on average, and on days when loneliness was lower than a person's average, they had fewer and less severe physical health symptoms. Additionally, participants who were more stable in loneliness across 8 days had less severe physical health symptoms. Further, there was a stronger association between instability in loneliness and more physical health symptoms for people who were lonelier on average. Finally, the increase in physical health symptom severity associated with WP loneliness was strongest for participants with low variability in loneliness.

Conclusion: Loneliness is associated with physical health symptoms on a day-to-day basis, especially for people who are highly variable in loneliness. Considerations of multiple sources of variation in daily loneliness may be necessary to adequately address loneliness and promote health. Public health interventions addressing loneliness may be most effective if they support social connectedness in people's everyday lives in ways that promote stable, low levels of loneliness.

Objective: Aiming to identify potential intervention targets to achieve more equitable outcomes from behavioral weight loss (BWL) programs, the current study examined whether Black and White individuals experienced similar increases in physical activity (PA) engagement, perceived PA barriers, and PA enjoyment during an 18-month BWL program.

Method: Adults (N = 290) enrolled in an 18-month BWL program from 2014 to 2016 completed accelerometer-based measurements of moderate-to-vigorous PA and self-reported measures of PA barriers and enjoyment at months 0, 6, 12, and 18.

Results: Black participants had significantly fewer minutes of PA than White participants at baseline, 6, 12, and 18 months. Black participants reported fewer barriers to PA than White participants at 0 and 6 months but not at 12 or 18 months. They also reported higher PA enjoyment than White participants at 0 and 6 months but not at 12 or 18 months. Furthermore, whereas White participants had a significant reduction in PA barriers and an increase in PA behavior overtime, Black participants did not. There was no interaction between race and time on PA enjoyment.

Conclusions: Traditional BWL interventions may be ineffective for promoting PA among Black participants and may not appropriately address the unique PA barriers that Black participants experience. An improved understanding of differences in PA behaviors during BWL among Black and White individuals could help delineate why Black participants do not appear to benefit as much as White participants from traditional BWL programs and inform intervention strategies.

Objective: Received social support undermining engagement in life activities of individuals with chronic pain (e.g., solicitousness, support for functional dependence) is consistently correlated with worse physical functioning, pain severity, and disability. Whether such responses lead to worse pain outcomes (operant model of pain) or the latter lead to more supportive responses undermining activity engagement (social communication and empathy models of pain) is unknown, given the lack of cross-lagged panel studies. Furthermore, the mediating role of activity patterns in such relationships over time is entirely unclear. This study aimed to bridge these gaps.

Method: This was a 3-month prospective study with three waves of data collection (T1-T3; 6-week lag in-between), including 130 older adults (71% women; M_age = 78.26) with musculoskeletal chronic pain attending day-care centers. At every time point, participants filled out self-report measures of staff social support for functional dependence, activity patterns, physical functioning, pain severity, and interference. Scales showed good/very good test-retest reliability (ICC = .74-.96) and internal consistency (all α > .90).

Results: Parsimonious cross-lagged panel mediation models showed the best fit (χ²/df < 2.44; CFI > .96; GFI > .93; RMSEA < .09). Bidirectional effects were found over time, but poorer pain outcomes at T1 (higher pain severity/interference, lower physical functioning) more consistently predicted higher social support for functional dependence than vice versa. Poorer pain outcomes (T1) predicted more avoidance/less overdoing (T3), via increased received support for functional dependence (T2).

Conclusion: Further research on the cyclical relationships between the study variables across chronic pain trajectories is needed to harness the power of interpersonal relationships in future self-management interventions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: A change toward Eveningness in circadian sleep-wake behavior is generally seen from childhood to adolescence, but less is known about circadian changes during adulthood. Circadian changes during mid-adulthood are of high interest, since Eveningness associates with a range of health-related problems, including psychological symptoms and mental disorders. In this study, we examined the circadian stability across 10 years, from 42 to 52 years of age, and how it is associated with sleep and mental health in a Finnish general population cohort follow-up-based (n = 976). Method: Circadian type was assessed at both ages with a widely used item for self-estimated Morningness/Eveningness from the original Horne-Östberg Morningness-Eveningness Questionnaire. Generalized estimating equations were used for analyzing how a change in Morningness/Eveningness was associated with sleep and mental health longitudinally. Results: Our findings indicate that the circadian type is a highly stable trait during mid-adulthood with mainly moderate changes occurring in 42.2% of adults and no circadian change among 57.8% of adults. Most changes occurred within the same circadian type (23.9%), second to changes between moderate circadian types (13.3%). Changes between the Definite Evening-types and Morning-types were very rare (0.5%). Stable Evening-types reported more insufficient sleep, discrepancy between sleep duration on workdays and free days, and depression as compared to stable Morning-types. Moderate changes toward Morningness, comprising mostly those within Morning-types, were associated with reduced distress and psychological symptoms. Conclusions: In conclusion, our findings show high stability of mid-adulthood circadian type. However, changes toward Morningness seem to be associated with improved mental health.
