Enabling, Not Cultivating: Received Social Support and Self-Efficacy Explain Quality of Life After Lung Cancer Surgery

Social isolation, coping efficacy, and social well-being over time in patients with lung cancer

BACKGROUND

Little work has examined how coping efficacy and lung cancer-related social isolation relate to social well-being in the context of a patient's computed tomography (CT) scan. Researchers tested the cross-sectional relationship of social isolation and social well-being, and the longitudinal relationship between coping efficacy and social well-being before CT scans.

METHOD

25 patients with lung cancer, within 6 months of their upcoming CT scan, participated. Baseline surveys collected clinical information, demographics, and social isolation; repeated monthly surveys collected coping efficacy and social well-being every 30 days until one's scan.

RESULTS

[Cross-sectional] High levels of social isolation were associated with low levels of social well-being. [Longitudinal] On months patients reported high coping efficacy, they also reported increases in social well-being.

CONCLUSIONS

Social interventions may improve well-being among those with lung cancer as our work shows that getting and receiving support are strongly related to well-being in the time surrounding a scan.

Effectiveness of Roy Adaptation Model-Based Cognitive Stimulation Therapy in Elderly Patients with Non-Small Cell Lung Cancer Undergoing Curative Resection

This study aimed to investigate the effects of a Roy adaptation model (RAM)-based cognitive stimulation therapy (CST) intervention on elderly patients diagnosed with primary non-small cell lung cancer (NSCLC) undergoing curative resection. A total of 280 patients diagnosed with primary NSCLC were randomized into RAM-based CST group and control group. Outcomes were assessed at three intervals: pre-surgery, discharge, and one-month post-discharge. Cognitive function was evaluated using Mini-Cognitive test. Postoperative delirium prevalence was determined within 48 hours post-surgery using Nursing Delirium Screening Scale. The Hospital Anxiety and Depression Scale evaluated anxiety and depression symptoms, while Quality of Life (QoL) was assessed via Short Form-36 (SF36) Health Survey. The RAM-based CST group demonstrated significantly higher Mini-Cog test scores than the control group upon discharge and post-intervention. Patients with RAM-based CST exhibited a decrease in postoperative delirium compared to the control group. The RAM-based CST intervention yielded an improvement in anxiety and depression at discharge and 1-month post-discharge compared to preoperative levels. Additionally, the RAM-based CST group exhibited substantial enhancements in SF36 subcategory scores at 1-month post-discharge compared to pre-surgery. At post-intervention, the RAM-based CST group demonstrated significantly higher scores than the control group across various health-related domains, including role limitations due to emotional problems, mental health, general health perception, bodily pain, and role limitations due to physical problems. The RAM-based CST intervention in elderly NSCLC patients undergoing curative resection yielded significant enhancements in cognitive function, reduced delirium incidence, improved emotional well-being, and better QoL postoperatively.

An Integrative Medicine Educational Program for Radiation Oncology Patients: Patient-Reported Outcomes

Purpose

Complementary health approaches (CHAs) equip patients to self-manage radiation therapy (RT)-related symptoms and fulfill unmet needs, but few disclose CHA use to their radiation oncologist. An integrative medicine educational program (IMEP) was developed to assess its ability to improve patient self-efficacy for symptom management and CHA use disclosure.

Methods and Materials

The IMEP included 4 1-hour sessions covering topics of (1) meditation, (2) yoga, (3) massage therapy, and (4) nutrition. Individuals over age 18 years and actively receiving RT were administered presession and postsession surveys. The primary outcomes were intention to disclose CHA use and self-efficacy. Qualitative data were assessed with a thematic approach.

Results

Overall, 23 patients attended 1 or more sessions, yielding 43 completed surveys. Compared with 35.9% of participants who had disclosed CHA use before the session, 67.4% intended to disclose after the session. Of the 5 self-efficacy statements, there were significant improvements in "I have ownership over my health" (increase of 0.42; 95% CI, 0.07-0.77; P = .01), "I have tools to manage my disease on my own" (1.14; 95% CI, 0.42-1.87; P = .001), and "I have control over my cancer" (0.96; 95% CI, 0.39-1.53; P < .001). Barriers to involvement included transportation, timing relative to RT appointment, and poor performance status.

Conclusions

A radiation-specific IMEP resulted in a high rate of intention to disclose CHA use and improvements in patients' reported self-efficacy to manage radiation-related symptoms. However, substantial resources were needed to deliver the IMEP. Future work must focus on increasing accessibility through telehealth and flexible timing.

Mediating effects of general self-efficacy on social support and quality of life in patients after surgical aortic valve replacement

AIM

To explore whether general self-efficacy can mediate the relationship between social support and quality of life in patients after surgical aortic valve replacement.

DESIGN

A cross-sectional design.

METHODS

The final analysis included 283 patients who underwent surgical aortic valve replacement from May 2021 to September 2021. They completed a set of questionnaires, including the Chinese version of the General Self-Efficacy Scale, the Chinese Questionnaire of Quality of life in Patients with Cardiovascular Diseases and the Social Support Rating Scale. The PROCESS Macro in SPSS was used to analyse the mediating effect.

RESULTS

Quality of life and all of its dimensions were significantly related to social support and general self-efficacy. A significant indirect effect of social support existed through general self-efficacy in relation to quality of life with the mediation effect ratio of 32.82%.

Postoperative Symptom Burden in Patients Undergoing Lung Cancer Surgery

CONTEXT

Previous studies on quality of life (QOL) after lung cancer surgery have identified a long duration of symptoms postoperatively. We first performed a systematic review of QOL in patients undergoing surgery for lung cancer. A subgroup analysis was conducted focusing on symptom burden and its relationship with QOL.

OBJECTIVE

To perform a qualitative review of articles addressing symptom burden in patients undergoing surgical resection for lung cancer.

METHODS

The parent systematic review utilized search terms for symptoms, functional status, and well-being as well as instruments commonly used to evaluate global QOL and symptom experiences after lung cancer surgery. The articles examining symptom burden (n = 54) were analyzed through thematic analysis of their findings and graded according to the Oxford Centre for Evidence-based Medicine rating scale.

RESULTS

The publication rate of studies assessing symptom burden in patients undergoing surgery for lung cancer have increased over time. The level of evidence quality was 2 or 3 for 14 articles (cohort study or case control) and level of 4 in the remaining 40 articles (case series). The most common QOL instruments used were the Short Form 36 and 12, the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire, and the Hospital Anxiety and Depression Score. Thematic analysis revealed several key findings: 1) lung cancer surgery patients have a high symptom burden both before and after surgery; 2) pain, dyspnea, cough, fatigue, depression, and anxiety are the most commonly studied symptoms; 3) the presence of symptoms prior to surgery is an important risk factor for higher acuity of symptoms and persistence after surgery; and 4) symptom burden is a predictor of postoperative QOL.

CONCLUSION

Lung cancer patients undergoing surgery carry a high symptom burden which impacts their QOL. Measurement approaches use myriad and heterogenous instruments. More research is needed to standardize symptom burden measurement and management, with the goal to improve patient experience and overall outcomes.

Social cognitive mechanisms in healthcare worker resilience across time during the pandemic

PURPOSE

Healthcare workers are at increased risk for mental health problems during disasters such as the COVID-19 pandemic. Identifying resilience mechanisms can inform development of interventions for this population. The current study examined pathways that may support healthcare worker resilience, specifically testing enabling (social support enabled self-efficacy) and cultivation (self-efficacy cultivating support) models.

METHODS

Healthcare workers (N = 828) in the Rocky Mountain West completed self-report measures at four time points (once per month from April to July of 2020). We estimated structural equation models to explore the potential mediating effects that received social support and coping self-efficacy had (at time 2 and time 3) between traumatic stress symptom severity (at time 1 and time 4). Models included covariates gender, age, minority status, and time lagged co-variations between the proposed mediators (social support and coping self-efficacy).

RESULTS

The full model fit the data well, CFI = .993, SRMR = .027, RMSEA = .036 [90% CIs (0.013, 0.057)]. Tests of sequential mediation supported enabling model dynamics. Specifically, the effects of time 1 traumatic stress severity were mediated through received social support at time 2 and time 3 coping self-efficacy, in sequential order to reduce time 4 traumatic stress severity.

CONCLUSIONS

Findings show the importance of received social support and coping self-efficacy in mitigating psychopathology risk. Interventions can support mental health by focusing on social resource engagement that facilitates coping empowerment, which may decrease risk for mental health job-related problems among frontline healthcare workers exposed to highly stressful events.

3Cs: the experiences of informal caregivers of patients undergoing thoracic surgery

The informal caregiver is pivotal to the postoperative experience of patients. The purpose of this study was to explore the informal caregivers' experience while accompanying patients through thoracotomy surgery. Specifically, and exclusively, the informal carers' personal reactions, needs and views regarding their experience in the patients' surgery trajectory were explored. A convenience sample of eight informal caregivers of patients who had undergone thoracotomy were interviewed approximately 2 weeks following discharge from a general hospital in Malta. The findings revealed knowledge regarding participants' experiences of demands and fears associated with the 3Cs: cancer, challenges and coping. The impact of timely information-sharing and support on the informal caregiver's experience was highlighted. These findings suggest that careful consideration of both a patient's and informal caregiver's needs promotes an enhanced hospitalisation experience, and creates opportunity for a better transition back home. Implications for research and practice are discussed.

Parental self-efficacy and family quality of life in parents of children with autism spectrum disorder in China: The possible mediating role of social support

OBJECTIVE

This study explored the related factors of FQOL in parents of children with ASD and examined whether social support mediates the relationship between parental self-efficacy and FQOL in parents of children with ASD.

DESIGN AND METHODS

Using a cross-sectional design, a total of 260 parents of children with ASD were recruited from September 2019 to November 2020. They completed the Beach Center Family Quality of Life Scale, the Parenting Sense of Competence Scale, and the Social Support Rating Scale.

RESULTS

Parental self-efficacy and social support explained approximately 49.5% of the variance in FQOL. After controlling for the confounding influence of parents' education level, parental self-efficacy had a direct effect on FQOL (β = 0.292, SE = 0.108, P < 0.01) and an indirect effect on FQOL (β = 0.165, SE = 0.069, P < 0.01). Effects were mediated through social support, with partial mediating effects accounting for 36.11% of the total effect.

CONCLUSIONS

Both parental self-efficacy and social support are critical to promoting FQOL, and a partial mediating effect of social support was established.

PRACTICAL IMPLICATIONS

Interventions for families with children with ASD should focus on enhancing parental self-efficacy, followed by a perceived social support and FQOL prompt.

Cultivation or enabling? Day-to-day associations between self-efficacy and received support in couples

OBJECTIVE

Theories and empirical findings identify social support and self-efficacy as important variables for behavior change. Two competing hypotheses describe the bidirectional relationship of these two constructs: The cultivation hypothesis assumes that self-efficacy facilitates social support, whereas the enabling hypothesis assumes that social support fosters self-efficacy. To shed more light on the interplay of interpersonal and intrapersonal factors in the behavior change context in daily life, the present study aims to investigate these hypotheses at the within-person level.

METHODS

In total, 99 overweight heterosexual couples intending to increase their physical activity participated in this dyadic intensive longitudinal study. Both partners independently reported on their self-efficacy and their support receipt from their partner in smartphone-based end-of-day diaries across 14 days. To investigate the competing hypotheses prospective lagged multilevel models were applied.

RESULTS

For both partners, higher-than-average levels of self-efficacy on a given day predicted higher support receipt the next day, confirming the cultivation hypothesis. We found no effect of higher-than-average levels of support receipt on a given day on self-efficacy the next day, disconfirming the enabling hypothesis. Same-day support receipt and previous day self-efficacy were positively related to daily physical activity.

CONCLUSIONS

This is the first study investigating the cultivation and the enabling hypothesis on a day-to-day basis using a dyadic intensive longitudinal approach. Findings support the cultivation hypothesis at the within-person level, suggesting that self-efficacy may help to facilitate support receipt close in time. Future studies should use within-person experimental designs and ecological momentary assessments within days to increase our understanding of the temporal dynamics of the cultivation and enabling effect.

Evolution and impact of self-efficacy during French COVID-19 confinement: a longitudinal study

Based on social cognitive theory, we propose that self-efficacy is a personal resource that protects people from the impact of confinement in the context of the COVID-19 pandemic. In a longitudinal study where 197 French citizens were surveyed over 8 weeks of confinement (though only 25 participants responded each of these 8 weeks), we examined the relationships between general self-efficacy and positive affect, negative affect and adaptive performance at work. Consistent with theoretical expectations, self-efficacy was relatively stable during confinement and was positively related to positive affect and negatively related to negative affect. Self-efficacy was also positively correlated with all dimensions of adaptive performance at work during confinement. The role of self-efficacy as a protective factor against depressive risks induced by the stressful COVID-19 pandemic is discussed.

Self-efficacy for Coping with cancer: Psychometric properties of the Cancer Behavior Inventory version 3.0 - Korean

PURPOSE

To validate the Cancer Behavior Inventory version 3.0 - Korean (CBI 3.0 - K), a holistic measure of self-efficacy for coping with cancer by including spiritual coping subscale.

METHOD

Psychometric properties of the CBI 3.0 - K were evaluated among 453 cancer patients. Confirmatory factor analysis was conducted to examine structural validity. Internal consistency was measured with Cronbach's alpha. For convergent validity, correlations with the Functional Assessment of Cancer Therapy-Gastric Gastric Cancer Subscale (GaCS), the Hospital Anxiety and Depression Scale (HADS), the Multidimensional Scale of Perceived Social Support (MSPSS), the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACT-Sp) subscale and the European Organization for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ-C30) Global Health Status/QoL subscale were analyzed.

RESULTS

The CBI 3.0 - K supported the original 7 factor structure of the CBI Version 3.0 with relocation of one item which reflected self-efficacy for coping utilizing personal resources. High levels of internal consistencies were demonstrated. Convergent validity was established with moderate to strong correlations with the GaCS, the HADS, the FACIT-Sp, and the EORTC QLQ-C30 subscales, and moderate correlation with the MSPSS. Known group validity with the Using Spiritual Coping subscale was demonstrated.

CONCLUSIONS

The CBI 3.0 - K will facilitate comprehensive assessment of patients' self-efficacy for coping by including spiritual coping subscale. Assessment on responsiveness of the CBI 3.0 - K to interventions designed to enhance coping is strongly recommended.

Cultivation and Enabling Effects of Social Support and Self-Efficacy in Parent-Child Dyads

Background

There are two alternative mechanisms, elucidating the reciprocal relationship between self-efficacy and social support when explaining health outcomes: self-efficacy beliefs may operate as the establisher of social support (the cultivation model) or social support may enable the formation of self-efficacy beliefs (the enabling model).

Purpose

In line with the cultivation hypothesis, it was tested if self-efficacy (measured in parents and children) would indirectly predict parental and child moderate-to-vigorous physical activity (MVPA), via the mediator, social support (parent-provided, child-received). In line with the enabling hypothesis, it was tested if social support would predict MVPA indirectly, via the mediator, self-efficacy.

Methods

A total of 879 parent–child dyads (1758 individuals; 52.4% girls, aged 5–11 years old, 83.2% mothers) provided self-reports at the baseline (T1) and the 7- to 8-month follow-up (T2). Body weight and height were measured objectively. Manifest path analyses were performed, controlling for the baseline levels of the mediator and dependent variables.

Results

A similar number of significant simple indirect effects was found for the cultivation and the enabling model. Across the models, the indirect effects followed similar patterns: (a) within-individual indirect effects in children; (b) across-individual indirect effects, with the independent variable measured in children and the mediator/dependent variables measured in parents (e.g., child self-efficacy predicted parental support provision and, indirectly, parental MVPA); (c) across-individual indirect effects, accounting for self-efficacy and MVPA measured in children, combined with parental reports of social support.

Conclusions

The findings provide support for both cultivation and enabling models in the context of MVPA among parent–child dyads.

Examining Variation in Emotional Distress among Individuals with a Cancer Diagnosis

This study examined whether emotional distress among U.S. adults diagnosed with cancer was influenced by death rates, survival rates, and new cases based on cancer type and individual-level variables (health efficacy, perceived health, and use of information and communication technologies and social media for health-related reasons). Health Information National Trends Survey 5 data from cycle 1 and cycle 2 were used to examine emotional distress among individuals who had experienced 1 of 17 different types of cancer diagnoses. A multilevel model and follow-up one-way ANOVA indicated a small statistically significant difference in emotional distress across cancer types. To investigate the influence of individual-level variables on emotional distress, a hierarchical regression analysis indicated that, after controlling for perceived health and health efficacy, using social media in a greater number of health-related ways significantly predicted greater emotional distress, while using information and communication technologies in a greater number of health-related ways did not.

The effect of cognitive dysfunction on mid- and long-term mortality after vascular surgery

Background

In recent decades, previous studies have noted the importance of frailty, which is a frequently used term in perioperative risk evaluations. Psychological and socioeconomical domains were investigated as part of frailty syndrome. The aim of this study was to assess the importance of these factors in mortality after vascular surgery.

Methods

In our prospective, observational study (ClinicalTrials.gov Identifier: NCT02224222), we examined 164 patients who underwent elective vascular surgery between 2014 and 2017. At the outpatient anaesthesiology clinic, patients completed a questionnaire about cognitive functions, depression and anxiety, social support and self-reported quality of life were assessed using a comprehensive frailty index, in addition to medical variables. Propensity score matching was performed to analyse the difference between patients and controls in a nationwide population cohort. The primary outcome was 4 year mortality. The Kaplan-Meier method and Cox regression analysis were used for statistical analyses.

Results

The patients’ mean age was 67.05 years (SD: 9.49 years). Mini-Mental State Examination scores of less than 27 points were recorded for 41 patients. Overall mortality rates were 22.4 and 47.6% in the control and cognitive impairment groups, respectively (p = 0.013). In the univariate Cox regression analysis, cognitive impairment measured using age- and education-adjusted MMSE scores increased the risk of mortality (AHR: 2.842, 95% CI: 1.389-5.815, p = 0.004).

Conclusion

Even mild cognitive dysfunction measured preoperatively using the MMSE represents a potentially important risk factor for mortality after vascular surgery.

Health-Related Quality of Life After Lobectomy for Lung Cancer: Conceptual Framework and Measurement

BACKGROUND

Lung cancer surgery has a significant impact on health-related quality of life (HRQOL). In prior studies of HRQOL after lung cancer surgery, researchers selected the HRQOL domains of interest. To increase the patient-centeredness of these studies, we conducted a qualitative study to ascertain which aspects of HRQOL are most relevant to them postoperatively and to identify Patient-Reported Outcome Measurement Information System measures most germane to patients undergoing lobectomy for lung cancer.

METHODS

We conducted in-depth semistructured interviews with 25 patients after lobectomy for lung cancer to solicit input regarding the physical, social, and emotional HRQOL domains relevant after surgery. Interviews were transcribed verbatim, and a thematic content analysis to identify HRQOL themes was performed. Themes were integrated to create a conceptual framework to guide outcome measurement selection.

RESULTS

Qualitative analysis indicated that within the physical health domain, patients were most concerned about general physical function (100% of participants), pain (96%), fatigue (96%), and dyspnea (76%). Neuropathic pain was reported by 28% of participants. Instrumental (100%) and emotional social support (88%) and positive emotions/relief/hope (96%) were also important. Two cross-cutting themes were the desire to maintain independence (32%) and preparing for surgery/expectations (92%).

CONCLUSIONS

Our results indicate that a number of physical, social, and emotional HRQOL domains are relevant after lobectomy for lung cancer. These domains are currently represented by Patient-Reported Outcome Measurement Information System measures and can be readily assessed for clinical or research purposes.

Pain and Opioid Use After Thoracic Surgery: Where We Are and Where We Need To Go

As many as one third of patients undergoing minimally invasive thoracic surgery and one half undergoing thoracotomy will have chronic pain, defined as pain lasting 2 to 3 months. There is limited information regarding predictors of chronic pain and even less is known about its impact on health-related quality of life, known as pain interference. Currently, there is a focus on decreased opioid prescribing after surgery. Interestingly, thoracic surgical patients are the least likely to be receiving opioids before surgery and have the highest rate of new persistent opioid use after surgery compared with other surgical cohorts. These studies of opioid use have identified important predictors of new persistent opioid use, but their findings are limited by failing to correlate opioid use with pain. The objectives of this invited review are to present the findings of pertinent studies of chronic pain and opioid use after thoracic surgery, "where we are," and to discuss gaps in our knowledge of these topics and opportunities for research to fill those gaps, "where we need to go."

Inter-Relations between Partner-Provided Support and Self-Efficacy: A Dyadic Longitudinal Analysis

BACKGROUND

Existing evidence indicates that social support may enhance recipients' self-efficacy (enabling hypothesis) or that self-efficacy facilitates support receipt (cultivation hypothesis). However, less is known about the time-lagged support-self-efficacy relationship in couples. Our aim was to disentangle reciprocal interrelations among stable and time-varying components of support provision and self-efficacy in couples over time.

METHODS

We conducted secondary analyses of a published randomised controlled trial with six assessments, spanning 1 year and N = 338 heterosexual couples (age range: 18-80 years). Women's and men's reports on physical activity-specific provided support and physical activity-specific self-efficacy were analysed.

RESULTS

Based on the actor-partner interdependence model, we compared nested random intercepts cross-lagged panel models. The final model revealed no gender effects. Stable levels of both partners' support provision and self-efficacy were positively associated. At the time-varying level, one partner's self-efficacy predicted the other partner's support provision later on. No lagged-association emerged for the opposite predictive direction.

CONCLUSIONS

Partners' stable shares of provided support and self-efficacy were interrelated, whereas higher time-varying self-efficacy of one partner seemed to activate support provision from the other partner, confirming the cultivation hypothesis but not the enabling hypothesis.

Efficacy of an Internet-based intervention for job stress and burnout among medical professionals: study protocol for a randomized controlled trial

BACKGROUND

Medical professionals are at high risk of job stress and burnout. Research shows that work-related stress can be reduced through enhancing psychological resources, in particular, self-efficacy and perceived social support. These psychological resources can operate either individually or sequentially: in line with the cultivation hypothesis, self-efficacy precedes and cultivates perceived social support, whereas according to the enabling hypothesis it is perceived social support that comes first and enables self-efficacy. Based on this theoretical framework we developed an internet-based intervention, Med-Stress, dedicated to healthcare providers and aimed at reducing job stress and burnout. Med-Stress contains two modules that enhance self-efficacy and perceived social support, which are tested in four variants reflected in four study conditions. We expect that sequential enhancement of resources: self-efficacy and social support or social support and self-efficacy will yield larger posttest results than individual enhancement.

METHODS

In this four-arm randomized controlled trial we will test four variants of the Med-Stress intervention. The trial is open for professionally active medical providers aged at least 18 years (N = 1200) with access to an Internet-connected device. We will compare the effects of two experimental conditions reflecting cultivation and enabling effects of self-efficacy and perceived social support (sequential enhancement of resources), and two active controls strengthening self-efficacy or perceived social support. Job stress and job burnout will be the primary outcomes, whereas depression, job-related traumatic stress, and work engagement will be secondary ones. Additionally, we will measure perceived social support, self-efficacy to manage job stress and burnout, and the ability to obtain social support, exposure to traumatic events, and users' expectancy and credibility of the intervention. All assessments will be applied before the intervention, at posttest (at 3 or 6 weeks depending on the study condition), and at 6-month and 12-month follow up. In the case of experimental groups, additional measurements will be taken after enhancing each resource.

DISCUSSION

Resource-based interventions are relatively context-free and could potentially benefit medical professionals across the field. If Med-Stress is successful, its most effective variant could be implemented in the healthcare system as a standalone, supportive tool for employees.

A Review of Quality of Life Measures used in Surgical Outcomes for Stage I Lung Cancers

This review summarizes the literature on QoL in early stage lung cancer patients who underwent surgery. PubMed and PsycINFO were searched. Twelve articles from 10 distinct studies were identified for a total of 992 patients. Five QoL measures were used. One study reported only on pre-surgical QoL, six only on post-surgical QoL and three studies reported on both pre- and post-surgical QoL. Timing for the administration of post-surgical QoL surveys varied. The literature on QoL in Stage I non-small-cell lung cancer patients is very sparse. Additional research is needed to explore the impact of different surgical approaches on QoL.

Why and for Whom May Coping Planning Have Adverse Effects? A Moderated Mediation Analysis

BACKGROUND

Coping planning, the formation of plans to overcome behavioral barriers is assumed to promote health behavior maintenance, but the literature on this is inconsistent. In this study, we aimed to investigate the mechanisms of a coping planning intervention that adversely affected maintained safe water consumption. We also explored perceived behavioral difficulty as a potential moderator of coping planning interventions.

METHODS

In the second phase of a cluster-randomised trial, households (N = 177 analyzed) were randomly allocated to a coping planning intervention or a comparison group (repetition of interventions from first intervention phase). Safe water consumption, the mechanisms of coping planning, and perceived difficulty were measured pre-post. The data were analyzed using mediation and moderated mediation analysis.

RESULTS

Changes in behavioral intention mediated the intervention effects on behavioral maintenance (b = -0.36, 95% CI [-0.91, -0.03]). Changes in perceived coping planning (b = 0.08, 95% CI [-0.12, 0.34]), and maintenance self-efficacy (b = -0.13, 95% CI [-0.45, 0.01]) did not mediate the effects. Prior perceived difficulty moderated the coping planning intervention effects on maintenance via intention.

CONCLUSIONS

Coping planning may decrease motivation for health behavior maintenance for persons who experienced few barriers prior to the planning intervention.

Inter-relations among negative social control, self-efficacy, and physical activity in healthy couples

OBJECTIVES

In romantic relationships, partners can influence each other's health-relevant behaviour by exerting negative social control (e.g., pressuring), however, with mixed success. To elucidate this phenomenon, we examined couples motivated to increase their physical activity and investigated the degree to which both partners exerted negative control on each other, their self-efficacy, reciprocal associations among the two behaviour-specific constructs, and their relationship with moderate-to-vigorous physical activity (MVPA).

DESIGN

This was a longitudinal study with three assessment periods (T0, T2, T3) spanning 7 weeks.

METHODS

We performed secondary analyses with data from the control condition (N = 113 heterosexual couples) of a published randomized controlled trial. Dyadic mediator models specified either both partners' self-efficacy as predictors and provided negative partner control to each other as mediators or vice versa. The outcomes comprised both partners' accelerometer-assessed MVPA. Mediators and outcomes were controlled for their T0 values.

RESULTS

The first model showed that women's and men's provided negative partner control (T0) was positively related to the other partners' self-efficacy (T2). Testing the alternative predictive direction, the second model showed that only women's self-efficacy (T0) was associated with more provided negative partner control (T2) by men. Women and men showed less MVPA (T3) when their partners had provided them with more negative control at T2.

CONCLUSIONS

As negative control provided to partners may be detrimental to their behaviour change, interventionists should advise couples to avoid it. However, active ingredients of negative control that may benefit recipients' self-efficacy beliefs should be investigated in future work. Statement of contribution What is already known on this subject? Couples often try to change each other's health behaviour not just using supportive tactics, but also controlling ones. Negative partner control (e.g., rebuking and nagging) was found to have adverse or no effects on control recipients' health behaviour change. To understand underlying mechanisms of this relationship, reactance and negative affect of recipients have been investigated, but only rarely their self-efficacy, a consistent individual predictor of behaviour change that is likely to share reciprocal relations with social exchange processes, including negative social control. What does this study add? Although harmful for behaviour change, negative partner control may increase control recipients' self-efficacy. Higher self-efficacy of one partner may also increase provided negative partner control by the other.

Sedentary behaviours and health-related quality of life. A systematic review and meta-analysis

Researchers have speculated that sedentary behaviour may reduce health-related quality of life (HRQOL), but the extent to which this is true remains unknown. Our study sought to systematically review and synthesise research on the relationship between sedentary behaviours and HRQOL and to investigate if these relationships are moderated by age, health status, and HRQOL domain. The review was registered with PROSPERO (no. CRD42016036342). We searched six electronic databases. The selection process resulted in including k = 27 original studies; k = 18 were included in a meta-analysis. Data were synthesised twice, using the methods of systematic review and meta-analysis, in order to reduce biases related to a small number of included studies. Both the systematic review and meta-analytical methods indicated that lower levels of sedentary behaviours were associated with higher physical HRQOL (estimate of average effect: r = -.140; 95% CI -.191, -.088). Moderator analyses indicated that associations between the physical HRQOL domain and sedentary behaviours may be similar in strength across age- and health status groups. Causal inferences could not be drawn as most studies were cross-sectional. Concluding, sedentary behaviours were related to better physical HRQOL but not reliably to mental and social HRQOL.
