Lifestyle changes after cancer treatment in patients and their partners: a qualitative study.

PURPOSE: Oncologists nowadays promote healthy lifestyle choices more often, focusing on diet, physical activity, smoking, alcohol consumption, and sleep, but the question is whether this is enough to establish actual change. As patients will have to achieve a healthy lifestyle at home in daily life, it is important to understand barriers and facilitators for lifestyle change for both patients and their partners. METHODS: A qualitative interview study was done among patients who received chemotherapy for testicular (n = 10) or breast cancer (n = 7) and their partners (n = 17). The interview focused on how much they remembered the lifestyle advice given in hospital, whether and what they had adapted since diagnosis, and what they deemed as facilitators and barriers in maintaining lifestyle change. RESULTS: Results showed that many patients and partners recalled that some advice was given in hospital but experienced this as too general and only at the start of treatment. Social contacts and the entire cancer experience helped facilitate change but were also seen as barriers. Other barriers were not considering healthy behaviors a priority or experiencing unhealthy choices as something nice after a trying time. CONCLUSIONS: Oncologists and hospitals that provide lifestyle advice should provide cancer- and person-specific lifestyle advice, should offer this advice repeatedly into survivorship, and include the partner, as they are dedicated to improving lifestyle as well. IMPLICATION FOR CANCER SURVIVORS: Staying healthy after cancer is important to both patients and their partners, and both experience their own facilitators and barriers to achieving this. Seeing a healthy lifestyle as a joint goal might facilitate change.

Disclosing a history of childhood cancer to romantic partners.

OBJECTIVE: To describe young adult childhood cancer survivors' disclosure of their cancer history (i.e., disclosure behavior, difficulty, and timing), perceived partner responses, and associations with relationship status satisfaction. METHODS: German long-term survivors of childhood cancer (N = 509; response rate: 31.3%, age 21-26, 59.7% female) completed a registry-based nationwide survey (embedded mixed methods design, including closed and open-ended questions) on measures about disclosure history (behavior, difficulty, and timing), partner responses, and relationship status satisfaction. Statistical (χ2 -, t-, or F-tests) and qualitative analyses were conducted. RESULTS: Half of all survivors always disclosed their cancer history to romantic partners. Thereby, three themes for considering (non-)disclosure were identified: Survivors' attitudes, having integrated cancer as part of their identity, and anticipated effects on romantic relationships. About 40% indicated having no difficulties with disclosing their cancer history. The timing of disclosure varied, with most survivors disclosing after a few dates. Facilitators of disclosure were the visibility of their former illness (e.g., scars), having trust in a (potential) partner, getting older/mature, and previous positive experiences with disclosure. Few survivors (13.8%) had ever experienced negative responses from dating partners. Yet, those who had negative experiences, found it more difficult to disclose their cancer history. Survivors were overall rather satisfied with their relationship status, with partnered survivors reporting greater satisfaction than singles (Hedge's g = 1.68); and particularly partnered survivors with past positive responses being most satisfied. CONCLUSIONS: Young adult childhood cancer survivors appear rather open in disclosing their cancer history to (potential) romantic partners, and few experienced negative responses. Psycho-educational programs may emphasize such findings in helping to prevent fear of disclosure or avoidance of dating and disclosure among survivors.

Contraceptive methods and fertility testing in young adult survivors of childhood cancer.

PURPOSE: Reproductive health is important, but often neglected in cancer survivorship care. This study explored contraceptive use and factors associated with fertility testing among young adult survivors of childhood cancer in Germany. METHODS: Young adult survivors of childhood cancer were identified through the German Childhood Cancer Registry and completed a mailed survey. Survivors were queried regarding contraceptive use, reproductive goals, uncertainty about fertility, and completion or interest in fertility testing. Multivariable stepwise logistic regression models were used to calculate Odds Ratios (OR) and 95% confidence intervals (CI) as a means of identifying factors associated with completion of and interest in fertility testing. RESULTS: Survivors (N = 472; 57.8% female; aged 23.3 ± 1.5 years, and 14.9 ± 5.0 years from diagnosis), reported high rates of contraceptive use, including 61.2% using a single method, 30.6% dual methods, and 8.1% no/less effective methods. Few survivors had completed fertility testing (13.0%), although 58.8% were interested. Having been diagnosed during adolescence (OR = 2.66, 95%CI: 1.39-5.09), greater uncertainty about fertility (OR = 1.16, 95%CI: 1.03-1.31), and use of dual contraceptive methods (OR = 1.94, 95%CI: 1.02-3.69) were associated with having completed fertility testing. Factors associated with interest in fertility testing included goals of wanting to have children (OR = 7.76, 95%CI: 3.01-20.04) and greater uncertainty about fertility (OR = 1.19 95%CI: 1.06-1.33). CONCLUSION: In this sample of young adults who survived childhood cancer, most reported contraceptive use. Few survivors had completed fertility testing, although more than half were interested. Interventions are needed to address potential barriers to fertility testing and help survivors manage fertility-related uncertainty.

Psychosexual Development and Sexual Functioning in Young Adult Survivors of Childhood Cancer.

BACKGROUND: Childhood cancer and its treatment can impair survivors' development throughout life, particularly psychosexual development, which can be affected in complex ways and is crucial for survivors' well-being. Yet, research is scarce. AIM: This study assessed psychosexual development (milestone attainment, age at attainment, perceived timing) in young adult survivors of childhood cancer. It further examined sexual satisfaction and sexual functioning, and whether survivors' perceived timing of sexual debut was related to satisfaction or functioning. METHODS: A registry-based nationwide survey was completed by N = 492 German survivors of childhood cancer (age 21-26 years, 6-26 years postdiagnosis). They completed standardized measures of psychosexual milestones (eg, first kiss, sexual debut), sexual satisfaction, and sexual functioning. Psychosexual development was compared to normative data (N = 1,533). OUTCOMES: Psychosexual development, sexual satisfaction, and sexual functioning were the primary outcome measures. Psychosexual development was characterized in three ways: milestone attainment (yes/no), age at attainment, perceived timing ("right" time, too early/late). RESULTS: Milestone attainment was comparable to normative data, except for sexual debut: Survivors were less often experienced (82.5% vs 88%; P = .002) and older at sexual debut (17.4 vs 16.2 years; g = 0.55), but most survivors (58.3%) perceived their timing as "right." Survivors of brain tumors were least likely to have had their sexual debut, but if experienced age at sexual debut was similar to other survivors. Female survivors were somewhat more experienced than males (eg, first kiss, first relationship; <10% difference), but they were somewhat older when they first kissed (g = 0.26). Age at diagnosis was unrelated to milestone attainment. Perceived early/late sexual debut was related to lower satisfaction in female survivors (P = .026), but unrelated to sexual dysfunction. Instead, partnered men reported particularly low dysfunction whereas women reported similar levels of sexual dysfunction irrespective of their relationship status (P = .049). Overall, sexual functioning was favorable (60.2%: not/barely problematic). CLINICAL IMPLICATIONS: Most survivors reported favorable sexual satisfaction and functioning, but a minority of survivors may need supportive services. STRENGTHS & LIMITATIONS: This project represents one of few large-scale studies on psychosexual development in childhood cancer survivors relative to normative data, and is the first to link development to sexual satisfaction/functioning. Assessing satisfaction/functioning with validated, but brief measures limits detailed insights, but was inclusive of any sexual orientation. Medical background information based on registry data was limited. CONCLUSION: Results showed normative psychosexual development (except for sexual debut) in most survivors. A self-determined attitude toward sexuality (ie, engaging in sexual activities at the "right" time) may generally determine positive sexual experiences. Lehmann V, Gerhardt CA, Baust K, et al.

How does the Untire app alleviate cancer-related fatigue? A longitudinal mediation analysis.

OBJECTIVE: A waiting-list randomized controlled trial supported the effectiveness of the multimodal Untire app in reducing cancer-related fatigue (CRF) in cancer patients and survivors. However, little is known about the causal mechanisms of different app components through which the intervention effect was achieved. We aim to examine whether specifically targeted factors (i.e., fatigue catastrophizing, depression, mindfulness, sleep, and physical activity) mediated the intervention effects of the Untire app on fatigue outcomes. METHODS: Seven hundred ninety-nine persons with CRF were randomized (2:1) into intervention (n = 519) and waiting-list control (n = 280) groups. Self-report data on the primary outcome fatigue severity and interference and the abovementioned potential mediators were collected at baseline and 12 weeks. Participants who completed the 12-week assessment were included in the analyses (intervention = 159; control = 176). We performed longitudinal multi-categorical multiple mediation analysis using PROCESS macro to examine whether the potential mediators explained the overall intervention effects. RESULTS: Improvements in fatigue catastrophizing (bootstrap 95% CI (-0.110; -0.011)), depression (bootstrap 95% CI (-0.082; -0.004)), and mindfulness (bootstrap 95% CI (-0.082; -0.002)), significantly mediated the intervention effect on fatigue severity, whereas sleep quality (bootstrap 95% CI (-0.081; 0.009)), sleep disturbance (bootstrap 95% CI (-0.038; 0.029)), and physical activity (bootstrap 95% CI (-0.068; 0.000)) did not. Similar associations were found for fatigue interference. CONCLUSIONS: Untire app access reduces fatigue severity and interference mainly by decreasing fatigue catastrophizing, depression, and by increasing mindfulness. Supporting these psychological mechanisms is crucial for reducing fatigue among cancer patients and survivors.

Web-based self-help intervention for partners of cancer patients based on acceptance and commitment therapy and self-compassion training: a randomized controlled trial with automated versus personal feedback.

PURPOSE: To evaluate the effectiveness of two versions (personal or automated feedback) of a psychological Web-based self-help intervention targeting partners of cancer patients. The intervention was based on acceptance and commitment therapy (ACT) and self-compassion training. Participants' adherence and their satisfaction were also studied. METHODS: Two hundred three partners of patients with heterogeneous entities of cancer were randomized into three conditions: personal feedback (PF) (n = 67), automated feedback (AF) (n = 70), or waiting list (WL) control (n = 66). Participants completed measures at baseline (T0) and post-intervention (T1; 3 months after baseline) to assess psychological distress (HADS; primary outcome), positive mental health, caregiver strain, general health (secondary outcomes), posttraumatic growth, resilience, self-compassion, psychological flexibility, sense of mastery, and relational communication style (process measures). Participants in the two experimental conditions also completed these measures at follow-up (T2; 6 months after baseline). RESULTS: There was no significant difference in change in psychological distress, positive mental health, caregiver strain and general health from T0 to T1 for either of the experimental conditions compared with the WL-condition. However, when compared to a WL-condition, the PF-condition was effective in increasing psychological flexibility (effect size d = 0.49) and resilience (d = 0.12) and decreasing overprotection (d = 0.25), and the AF-condition was effective in reducing overprotection (d = 0.36) and improving protective buffering (d = 0.36). At follow-up, the PF-condition was more effective than the AF-condition for improving mental health (d = 0.36), psychological flexibility (d = 0.60), mastery (d = 0.48), and protective buffering (d = 0.24). Participants positively appreciated the intervention and 69% participants were adherent. CONCLUSION: This study demonstrates that a Web-based intervention based on ACT and self-compassion training with automated or personal feedback does not seem to improve psychological distress; however, it may have the potential to support partners of cancer patients to cope with the difficult situation they are facing. The condition with personal feedback seemed to be more beneficial.

Smoking-Related Social Control in Indonesian Single-Smoker Couples.

BACKGROUND: The majority of Indonesian smokers are men and those who are married nearly always have a non-smoking wife (i.e. single-smoker couples). Previous studies have suggested that Indonesian women dislike smoking. However, contesting their husbands' smoking could be seen as disrespectful. In this study, we examine whether, and if so how, wives employ social control tactics to change their husbands' smoking and how the smokers perceive the tactics. METHOD: In-depth interviews (N = 12) with five single-smoker couples (N = 10 individual interviews) and two non-smoking wives of smokers (N = 2) were conducted in Jogjakarta, Indonesia. We used a social control framework and thematic analysis approach to analyse the transcribed interviews. RESULTS: Three themes emerged from smokers and their wives: (1) although the wives know that smoking is bad, they have to tolerate it, (2) wives and their husbands find it important to maintain harmony and (3) their family's needs serve as common ground. All the wives interviewed exerted social control to some degree, especially when they were pregnant or had children. Smokers reacted positively to social control and agreed to child-related house rules, but not to requests to give up smoking. CONCLUSION: Wives do exert social control and smokers are willing to accommodate and adapt their smoking. However, wives' influence on smoking may be limited in Indonesia, and focusing on managing their husbands' smoking at home rather than overall smoking might be more fruitful.

Beating cancer-related fatigue with the Untire mobile app: Results from a waiting-list randomized controlled trial.

OBJECTIVE: This waiting-list randomized controlled trial examined the effectiveness of a self-management mHealth app in improving fatigue and quality of life (QoL) in cancer patients and survivors. METHODS: Persons with cancer-related fatigue (CRF) were recruited across four English speaking countries, via social media, and randomized into intervention (n = 519) and control (n = 280) groups. Whereas the intervention group received immediate access to the Untire app, the control group received access only after 12-weeks. Primary outcomes fatigue severity and interference, and secondary outcome QoL were assessed at baseline, 4, 8, and 12-weeks. We ran generalized linear mixed models for all outcomes to determine the effects of app access (yes/no), over 12-weeks, following the intention-to-treat principle. RESULTS: Compared with the control group, the intervention group showed significantly larger improvements in fatigue severity (d = 0.40), fatigue interference (d = 0.35), and overall QoL on average (d = 0.32) (P's < .01), but not for overall QoL in the past week (P = .07). Sensitivity analyses indicated that participants with medium or high app use benefited most when compared with nonusers and control participants (P's ≤ .02). The intervention effect on fatigue interference was slightly stronger in younger participants (≤56 vs. >56). Effects did not depend on education and cancer status. Reliable change analyses indicated that significantly more people showed full recovery for fatigue in the intervention vs the control group (P's = .02). CONCLUSIONS: The Untire app can be an effective mHealth solution for cancer patients and survivors with moderate to severe CRF.

Parental protective and risk factors regarding cannabis use in adolescence: A national sample from the Chilean school population.

Background: Research has increased our understanding of the parental factors associated with the initiation and development of cannabis use disorder in adolescents, but few studies about this have been performed in middle- or low-income countries.Objective: First, to examine whether perceived past parental drug use, parental monitoring, and attitude toward adolescent cannabis use are associated with general and problematic cannabis use in Chilean adolescents. Second, to explore whether perceived past parental drug use weakens the associations of protective factors with general and problematic adolescent cannabis use.Methods: Regression analyses were performed on cross-sectional data from a multistage probabilistic sample stratified by clusters (municipalities, school and grade) of 43,060 students (47% male, mean age 15.5 years) from grades 8 to 12, which was collected from the Chilean National School Survey on Drug Use (2013).Results: Perceived past parental drug use increased the likelihood of adolescent cannabis use in general, but not its problematic use. Parental monitoring of adolescents' whereabouts and parental opposition to adolescent cannabis use decreased the likelihood of adolescent cannabis use in general, as well as problematic use. Perceived past parental drug use only interacted with parental monitoring of school activities.Conclusions: In line with research from the United States, the Netherlands and Spain, parental monitoring of adolescents' whereabouts and a strong parental opposition to cannabis use appear to be protective factors, irrespective of past parental use. However, the effectiveness of monitoring adolescents' school activities seems to decrease when parents are perceived as having used drugs in the past.

Impact of Painful Wound Care in Epidermolysis Bullosa During Childhood: An Interview Study with Adult Patients and Parents.

Epidermolysis bullosa (EB) is a group of rare inherited bullous skin disorders that differ in nature and severity. Currently, there is no cure for the disease. One of the complex problems of EB is the repetitive and painful care of skin wounds. The purpose of this study was to explore how adult patients and parents experienced the impact of wound care during childhood and which coping strategies they considered as helping. A qualitative study was performed, comprising semi-structured in-depth interviews with 7 adult patients and 6 parents. The impact, physically, psychologically and on daily life, was apparent for patients and parents. Helpful coping strategies were transferring care, regulating emotions, and dyadic strategies, such as supporting each other by distraction, encouragement, using rituals and collaboration. The most important finding of this study is the need for a more thorough investigation into the effectiveness of dyadic coping strategies.

The reciprocal relationship between daily fatigue and catastrophizing following cancer treatment: Affect and physical activity as potential mediators.

OBJECTIVE: Fatigue is a distressing symptom many cancer patients experience even after completion of treatment. Although theory and empirical evidence indicate that negative cognitions perpetuate fatigue after completion of treatment, insight into how this process unfolds in daily life is limited. This study used an intensive longitudinal design to investigate the reciprocal relationship between catastrophizing and fatigue in daily life and whether affective and behavioral processes mediate these relationships. METHODS: Post-treatment colorectal cancer patients (n = 101) completed daily diaries (14 days, 3 times daily) regarding their fatigue, catastrophizing, positive and negative affect, and physical activity. Multilevel modeling was applied to investigate within-person associations within days. RESULTS: Analyses revealed a positive reciprocal relationship between fatigue and catastrophizing throughout the day. That is, high levels of catastrophizing were associated with increases in fatigue within patients. In turn, but to a lesser extent, high levels of fatigue predicted increases in catastrophizing at the next assessment. Low positive affect and high negative affect mediated the effect of catastrophizing on increases in fatigue. Only negative affect mediated the reverse relationship. Physical activity did not mediate either relationship. CONCLUSIONS: This study provides evidence for a mutually reinforcing relationship between catastrophizing and fatigue in daily life, which might explain the perpetuation of fatigue after completion of cancer treatment. Fatigue-specific cognitive behavior therapy could be improved by educating patients about this daily reciprocal relationship, train them to quickly replace catastrophizing thoughts in daily life, and help them to cope with affective changes induced by fatigue.

Intent to use a web-based psychological intervention for partners of cancer patients: Associated factors and preferences.

This study examined partners of cancer patients intention to use a web-based psychological intervention, their preferences regarding its preconditions, functionalities and topics, and factors related to their intention. One hundred and sixty-eight partners completed a questionnaire about these aspects. Forty-eight percent of the partners would (maybe) make use of a web-based intervention. Partners who intended to participate were significantly younger, used the Internet more often, and perceived more caregiver strain. Most partners preferred an intervention that takes less than 1 hour/week, lasts five weeks or more, and contains information and peer support. Half of the partners would like to receive online guidance.

Psychosexual development and satisfaction in long-term survivors of childhood cancer: Neurotoxic treatment intensity as a risk indicator.

BACKGROUND: Risk factors for impairment in psychosexual development and satisfaction among adult survivors of childhood cancer are poorly understood. The authors compared psychosexual outcomes between survivors and healthy controls, and tested whether at-risk survivors can be identified by 1) treatment neurotoxicity or 2) diagnosis. METHODS: A total of 144 young adult survivors of childhood cancer and 144 matched controls completed questionnaires regarding psychosexual development, sexual satisfaction, and satisfaction with relationship status. Survivors were aged 20 to 40 years and were 5 to 34 years after diagnosis. Using medical chart data, survivors were divided into non-neurotoxic (48 survivors), low-dose (36 survivors), and high-dose (58 survivors) neurotoxic treatment groups. RESULTS: Apart from having fewer lifetime sex partners, survivors did not appear to differ from controls. However, survivors of brain tumors and any survivor who received high-dose neurotoxic treatment reported the lowest rates of achieving milestones of psychosexual development, whereas sexual and relationship status satisfaction were found to be related to relationship status. Neurotoxic treatment intensity further distinguished between survivors of brain tumors with and without psychosexual impairment. CONCLUSIONS: The intensity of neurotoxic treatment may be a valuable indicator of risk for psychosexual impairment relative to diagnosis alone. Health care providers should assess romantic/sexual problems among survivors at risk and make referrals if needed. Cancer 2017;123:1869-1876. © 2017 American Cancer Society.

The interdependence of posttraumatic stress symptoms in parental dyads during and after their child's treatment for cancer.

BACKGROUND: Cancer in a child is highly distressing and some parents are at increased risk for developing posttraumatic stress symptoms (PTSS). However, the interdependence of PTSS in parental dyads has rarely been accounted for. The aim was to explore the dyadic relationship of PTSS in parents of children diagnosed with cancer. MATERIAL AND METHODS: The sample includes 150 parents (75 dyads) of 75 children diagnosed with cancer in Sweden during 2002-2004, with follow-up until one year after end of treatment. Data on PTSS from six assessments were included. The first three assessments were carried out during treatment and the remaining after end of treatment. Actor-partner interdependence models were estimated using a structural equation modeling approach to explore the dyadic relationship of PTSS. Actor effects refer to intra-individual dependency over time, and partner effects refer to inter-individual dependency over time, i.e., how much an individual's symptom levels are affected by their partner's symptom levels at the previous assessment. RESULTS: Results show both actor and partner effects during the child's treatment. Only an actor effect remained following end of treatment where level of PTSS at one assessment was associated with the level of PTSS at the subsequent assessment. The association between mothers' and fathers' PTSS did not remain after end of treatment. CONCLUSIONS: Parents appear to react as an interdependent emotional system during the child's treatment but this effect disappears after end of treatment. Results suggest psychological interventions for parents during the child's cancer treatment should also be sensitive to and address the influence that distress in one partner may have on the other.

Satisfaction with sex life in sexually active heterosexual couples dealing with breast cancer: a nationwide longitudinal study.

BACKGROUND: A breast cancer (BC) diagnosis can profoundly affect the sex life of patient and partner within a couple. The purpose of the present study is to examine whether individual and partner sexual functioning, affectionate behavior, emotional closeness and depressive symptoms are associated with change over time in satisfaction with sex life of sexually active heterosexual couples dealing with BC and to explore whether the associations differ between patients and partners after adjustment for basic sociodemographic characteristics, comorbidity and BC treatment. MATERIAL AND METHODS: Women with BC and their male partners participated in a longitudinal study (Time 1, ≤4 months after surgery; Time 2, 5 months later). Participants completed items from the PROMIS® Sexual Function and Satisfaction measure (version 1.0), two items measuring affectionate behavior, a single item measuring emotional closeness and the Center for Epidemiologic Studies-Depression Scale. Registers provided sociodemographic and medical information. Multilevel models were used, which take the interdependency of couples' scores into account. RESULTS: A total of 287 sexually active couples were included in the analyses. Less vaginal discomfort and more vaginal lubrication were associated with increases in patients' satisfaction with sex life. Patients' and partners' satisfaction increased with higher ratings of their own orgasm ability and of partners' timing of ejaculation. Patients' reports of affectionate behavior were positively associated with their partners' satisfaction, and vice versa for partners. Patients' satisfaction increased the more emotional closeness their partner experienced. Partners' depressive symptoms were negatively associated with their satisfaction. Sociodemographic factors and BC treatment were not significantly associated with change in satisfaction. CONCLUSION: Satisfaction with sex life in sexually active couples dealing with BC needs to be seen as a couple issue. Health professionals should take the partner into account when addressing sexuality issues. Couples' functioning and relationship-related factors may be promising targets for couple interventions.

The impact of older person's frailty on the care-related quality of life of their informal caregiver over time: results from the TOPICS-MDS project.

PURPOSE: To examine the impact of changes in an older person's frailty on the care-related quality of life of their informal caregiver. METHODS: Five research projects in the TOPICS-MDS database with data of both older person and informal caregiver at baseline and after 12 months follow-up were selected. Frailty was measured in five health domains (functional limitations, psychological well-being, social functioning, health-related quality of life, self-rated health). Care-related quality of life was measured with the Care-Related Quality of Life instrument (CarerQoL-7D), containing two positive (fulfilment, perceived support) and five negative dimensions (relational problems, mental health problems, physical health problems, financial problems, problems combining informal care with daily activities). RESULTS: 660 older person/caregiver couples were included. Older persons were on average 79 (SD 6.9) years of age, and 61% was female. Caregivers were on average 65 (SD 12.6) years of age, and 68% was female. Results of the multivariable linear and logistic regression analyses showed that an increase in older person's frailty over time was related to a lower total care-related quality of life of the caregiver, and to more mental and physical health problems, and problems with combining informal care with daily activities at follow-up. A change in the older person's psychological well-being was most important for the caregiver's care-related quality of life, compared to the other health domains. CONCLUSIONS: Health professionals observing decreasing psychological well-being of an older person and increasing hours of informal care provision should be aware of the considerable problems this may bring to their informal caregiver, and should tailor interventions to support informal caregivers according to their specific needs and problems.

Caregiving demands and caregivers' psychological outcomes: the mediating role of perceived injustice.

OBJECTIVES: This study hypothesized that higher caregiving demands are related to higher perceived injustice. Furthermore, this study investigated the mediating role of perceived injustice in the link between caregiving demands and caregivers' psychological well-being. DESIGN: A cross-sectional design. SETTING: The Pain Centre of the university medical centre. SUBJECTS: Participants were 184 family caregivers of patients with chronic musculoskeletal pain. MAIN MEASURES: Participants completed questionnaires that assessed caregiving demands (i.e. The Dutch Objective Burden Inventory), perceived injustice (i.e. The Injustice Experience Questionnaire), how much they considered different sources responsible for the injustice they experienced (i.e. A newly developed inventory), perceived burden (i.e. The Zarit Burden Interview), distress (i.e. The Depression, Anxiety, and Stress Scale), and anger (i.e. The Hostility subscale of the Symptom Checklist-90-Revised). RESULTS: The findings showed that caregiving demands are significantly related to perceived injustice in family caregivers (r = .44; P < .001). Only a small group of family caregivers considered the patient or themselves responsible, but more than half of the caregivers considered healthcare providers at least somewhat responsible for the unjust situation. Finally, perceived injustice mediated the association between caregiving demands and burden (b = .11, CI: .04-.23) and distress (b = .05, CI: .006-.12), but not anger (b = .008, CI: -.01-.06). CONCLUSION: The findings suggest that perceived injustice plays an important role in the well-being of family caregivers and caregivers' well-being may be improved by changing their perceptions about their caregiving tasks and their condition.

Marijuana Use and Dependence in Chilean Adolescents and Its Association with Family and Peer Marijuana Use.

PURPOSE: The purpose of the study is to examine (1) whether family and peer marijuana use are independently related to adolescent marijuana use in Chile, (2) whether family and peer marijuana use are associated with adolescent marijuana dependence in adolescents using marijuana, and (3) whether the adolescent's age moderates the association between family or peer use and adolescent marijuana use and/or dependence. METHOD: This study used data from the National Survey on Drug Use in the General Population in Chile (a cross-sectional observational study), which was conducted in 2008 and 2010 in 4413 adolescents aged 12-19. Adolescents answered questions about their past-year marijuana use and dependence (ICD-10 criteria) and the marijuana use of their family and peers. Logistic regressions were performed while controlling for confounders. RESULTS: Adolescents who had a family member who used marijuana were five times more likely to use the drug. Adolescents with a close friend who used marijuana were eight times more likely to use marijuana. When adolescents were using marijuana, they were three times more likely to be dependent if they had a family member who used the drug. However, no significant relationship was found between peer use and dependence. No statistically significant interactions were found between family or peer use and age. CONCLUSION: Family and peer marijuana use was independently associated with adolescent's past-year marijuana use; however, only family marijuana use was statistically associated with adolescent's marijuana dependence.

The buffering effect of family functioning on the psychological consequences of headache.

The current study aimed to examine whether high family functioning mitigates the association between headache intensity and distress. The sample consisted of 124 patients with chronic or recurrent headache. Patients completed validated questionnaires about headache intensity, family functioning, and distress. Hierarchical regression analyses were performed to examine the interaction between headache intensity and family functioning on distress. Headache intensity was positively associated with distress (r = .28, p = .002). As hypothesized, family functioning moderated this association (B = -.01, p = .023). More specifically, the positive association between headache intensity and distress was significant only among patients with lower family functioning (B = .01, p < .001) and not among patients with higher levels of family functioning (B = .006, p = .075). Functional families appear to buffer the distress level in patients; they showed relatively low levels of distress regardless of the severity of their headache. In contrast, patients with dysfunctional families who experienced more pain reported more distress, presumably because they did not receive adequate help and support from these families. This study underlines the importance of a broader perspective on family dynamics in coping with pain.

Body issues, sexual satisfaction, and relationship status satisfaction in long-term childhood cancer survivors and healthy controls.

OBJECTIVE: Research on body image and sexual satisfaction after adult onset cancer has shown significant and lasting impairments regarding survivors' sexuality and romantic relationships. However, knowledge about these topics and their associations in adult survivors of childhood cancer is largely lacking. METHODS: Participants completed web-based questionnaires concerning body image, body dissociation, sexual satisfaction, and relationship status satisfaction (i.e., satisfaction with either being in a relationship or being single). Survivors (n = 87) and controls (n = 87) were matched on age and gender, with a mean age of 27 years (range: 20-40). Survivors were most often diagnosed with leukemia (46%), at an average of 16 years prior to study participation (range: 6-33 years). RESULTS: Similar numbers of survivors and controls were single (n = 24/31), in a committed relationship (n = 33/23), or married (n = 30/33). Survivors and controls reported comparable levels of body image, body dissociation, sexual experiences, and sexual and status satisfaction (d = 0.15-0.28). Higher status satisfaction was associated with being in a relationship (compared with being single, ß = 0.439), more positive body image (ß = 0.196), and higher sexual satisfaction (ß = 0.200). CONCLUSIONS: Adult survivors of childhood cancer were comparable to healthy peers regarding views of their bodies and psychosexual development, which was unexpected. Independent of whether people experienced cancer or not, their status satisfaction was associated with their relationship status, body image, and sexual satisfaction. Future research should explore why sexual and body problems are identified after adult onset cancer, whereas this seems to be less of a problem in childhood cancer survivors.
