    Input: Background : Cancer patients experience many physical and psychosocial problems for which they need support . WebChoice is an Internet-based , interactive health communication application that allows cancer patients to monitor their symptoms and problems , provides individually tailored information and self-management support , e-communication with expert cancer nurses , and an e-forum for group discussion with other patients . Objective : The objective of this study was to examine the effects of WebChoice on symptom distress ( primary outcome ) , depression , self-efficacy , health-related quality of life , and social support ( secondary outcomes ) . Methods : In this 1-year repeated- measures r and omized controlled trial , 325 breast and prostate cancer patients were r and omized into 1 experimental group  with access to WebChoice and 1 control group who received URLs of publicly available cancer Web sites . Results : Group differences on symptom distress were significant only for the global symptom distress index on the Memorial Symptom Assessment Scale ( slope estimate , −0.052 [ 95 % confidence interval , −0.101 to −0.004 ] ; t = 4.42 ; P = .037 ) . There were no significant group differences on secondary outcomes . Additional analyses showed significant within-group improvements in depression in the experimental group only . In the control group , self-efficacy and health-related quality of life deteriorated significantly over time . Conclusion : This r and omized controlled trial is one of the first to evaluate effects of an interactive health communication application to support cancer patients in illness management on symptoms . Although only 1 hypothesis was partially supported , the combined results show a clear trend toward better scores in the intervention group on most outcome measures . Implication s for Practice : If findings can be supported with additional research , WebChoice may become an important tool to support nursing care that can equip cancer patients to better manage their illness Abstract OBJECTIVE : Assess impact of a computer-based patient support system on quality of life in younger women with breast cancer , with particular emphasis on assisting the underserved . DESIGN : R and omized controlled trial conducted between 1995 and 1998 . SETTING : Five sites : two teaching hospitals ( Madison , Wis , and Chicago , Ill ) , two nonteaching hospitals ( Chicago , Ill ) , and a cancer re source center ( Indianapolis , Ind ) . The latter three sites treat many underserved patients . PARTICIPANTS : Newly diagnosed breast cancer patients ( N=246 ) under age 60 . INTERVENTIONS : Experimental group received Comprehensive Health Enhancement Support System ( CHESS ) , a home-based computer system providing information , decision-making , and emotional support . MEASUREMENTS AND MAIN RESULTS : Pretest and two posttest surveys ( at two- and five-month follow-up ) measured aspects of participation in care , social/information support , and quality of life . At two-month follow-up , the CHESS group was significantly more competent at seeking information , more comfortable participating in care , and had greater confidence in doctor(s ) . At five-month follow-up , the CHESS group had significantly better social support and also greater information competence . In addition , experimental assignment interacted with several indicators of medical underservice ( race , education , and lack of insurance ) , such that CHESS benefits were greater for the disadvantaged than the advantaged group . CONCLUSIONS : Computer-based patient support systems such as CHESS may benefit patients by providing information and social support , and increasing their participation in health care . These benefits may be largest for currently underserved population CONTEXT Rapid increases in access to the Internet have made it a viable mode for public health intervention . No controlled studies have evaluated this re source for weight loss . OBJECTIVE To determine whether a structured Internet behavioral weight loss program produces greater initial weight loss and changes in waist circumference than a weight loss education Web site . DESIGN R and omized , controlled trial conducted from April to December 1999 . SETTING AND PARTICIPANTS Ninety-one healthy , overweight adult hospital employees aged 18 to 60 years with a body mass index of 25 to 36 kg/m(2 ) . Analyses were performed for the 65 who had complete follow-up data . INTERVENTIONS Participants were r and omly assigned to a 6-month weight loss program of either Internet education ( education ; n = 32 with complete data ) or Internet behavior therapy ( behavior therapy ; n = 33 with complete data ) . All participants were given 1 face-to-face group weight loss session and access to a Web site with organized links to Internet weight loss re sources . Participants in the behavior therapy group received additional behavioral procedures , including a sequence of 24 weekly behavioral lessons via e-mail , weekly online su bmi ssion of self-monitoring diaries with individualized therapist feedback via e-mail , and an online bulletin board . MAIN OUTCOME MEASURES Body weight and waist circumference , measured at 0 , 3 , and 6 months , compared the 2 intervention groups . RESULTS Repeated- measures analyses showed that the behavior therapy group lost more weight than the education group ( P = .005 ) . The behavior therapy group lost a mean ( SD ) of 4.0 ( 2.8 ) kg by 3 months and 4.1 ( 4.5 ) kg by 6 months . Weight loss in the education group was 1.7 ( 2.7 ) kg at 3 months and 1.6 ( 3.3 ) kg by 6 months . More participants in the behavior therapy than education group achieved the 5 % weight loss goal ( 45 % vs 22 % ; P = .05 ) by 6 months . Changes in waist circumference were also greater in the behavior therapy group than in the education group at both 3 months ( P = .001 ) and 6 months ( P = .005 ) . CONCLUSIONS Participants who were given a structured behavioral treatment program with weekly contact and individualized feedback had better weight loss compared with those given links to educational Web sites . Thus , the Internet and e-mail appear to be viable methods for delivery of structured behavioral weight loss programs Purpose Patients undergoing radiotherapy for prostate cancer suffer from a variety of symptoms which influence health-related quality of life . We have developed an application ( Interaktor ) for smartphones and tablets for early detection , reporting and management of symptoms , and concerns during treatment for prostate cancer . The study evaluates the effect on symptom burden and quality of life when using the application for real-time symptom assessment and management during radiotherapy for localized prostate cancer . Methods A non-r and omized controlled study was used at two university hospitals in Sweden where 64 patients constituted a control group and 66 patients made up an intervention group . The intervention group was asked to report symptoms via the application daily during the treatment as well as 3 weeks after . The EORTC QLQ-C30 and its module PR25 and the Sense of Coherence question naire were administered at three time points in both groups . Results The intervention group rated significantly lower levels of fatigue and nausea at the end of radiotherapy . Moreover , they had significantly less burden in emotional functioning , insomnia , and urinary-related symptoms at the end of treatment as well as 3 months later compared with the control group . In the multivariate analyses , with education and sense of coherence as covariates , the intervention group still significantly rated emotional functioning ( p = 0.007 ) , insomnia ( p = 0.017 ) , and urinary-related symptoms ( p = 0.008 ) as better than the control group at T2 . ConclusionS tudy findings suggest that Interaktor could be an efficient mHealth tool for facilitating supportive care needs during cancer treatment PURPOSE Early breast cancer survivors ( BCSs ) report high unmet care needs , and easily accessible care is not routinely available for this growing population . The Breast Cancer E-Health ( BREATH ) trial is a Web-based self-management intervention to support the psychological adjustment of women after primary treatment , by reducing distress and improving empowerment . PATIENTS AND METHODS This multicenter , r and omized , controlled , parallel-group trial evaluated whether care as usual ( CAU ) plus BREATH is superior to CAU alone . BREATH is delivered in sixteen fully automated weekly modules covering early survivorship issues . Two to 4 months post-treatment , BCSs were r and omly assigned to receive CAU + BREATH ( n = 70 ) or CAU alone ( n = 80 ) using a stratified block design ( ratio 1:1 ) . Primary outcomes were distress ( Symptom Checklist-90 ) and empowerment ( Cancer Empowerment Question naire ) , assessed before r and om assignment ( baseline , T0 ) and after 4 ( T1 ) , 6 ( T2 ) , and 10 months ( T3 ) of follow-up . Statistical ( analysis of covariance ) and clinical effects ( reliable change index ) were tested in an intention-to-treat analysis ( T0 to T1 ) . Follow-up effects ( T0 to T3 ) were assessed in assessment completers . RESULTS CAU + BREATH participants reported significantly less distress than CAU-alone participants ( -7.79 ; 95 % CI , -14.31 to -1.27 ; P = .02 ) with a small-to-medium effect size ( d = 0.33 ) , but empowerment was not affected ( -1.71 ; 95 % CI , 5.20 to -1.79 ; P = .34 ) . More CAU + BREATH participants ( 39 of 70 [ 56 % ] ; 95 % CI , 44.1 to 66.8 ) than CAU-alone participants ( 32 of 80 [ 40 % ] ; 95 % CI , 30.0 to 51.0 ) showed clinical ly significant improvement ( P = .03 ) . This clinical effect was most prominent in low-distress BCSs . Secondary outcomes confirmed primary outcomes . There were no between-group differences in primary outcomes during follow-up . CONCLUSION Access to BREATH reduced distress among BCSs , but this effect was not sustained during follow-up Background Physical activity ( PA ) behavior change interventions among cancer survivors have used face-to-face , telephone , email , and print-based methods . However , computer-tailored , Internet-delivered programs may be a more viable option to achieve PA behavior change . Objective The objective of this study is to test the feasibility and preliminary efficacy of a Web-based PA behavior change program among cancer survivors . Methods Nova Scotian cancer survivors ( N=415 ) who previously expressed interest in a research study were approached . Interested participants were asked to complete an online assessment of PA and quality of life ( QOL ) before being r and omized to either a theory-based PA behavior change program using the PA tracking website UWALK ( UCAN ; n=48 ) or usual care ( UC ; n=47 ) . After the intervention ( 9 weeks ) , participants completed another  online assessment of PA and QOL  as well as measures to evaluate the program and website .  Descriptive analyses from surveys and Web analytic software were used to assess feasibility and mean change scores were used to test efficacy . Results Of all contacted survivors , 95 ( 22.3 % , 95/415 ) completed baseline measures and were r and omized with 84 ( 88 % , 84/95 ) completing the 9-week assessment . The behavior change program and website were rated highly on the satisfaction items . Average logins were 10.3 ( 1.1 per week ) and 26.0 % ( 111/432 ) of the weekly modules were completed . Most participants ( 71 % , 29/41 ) indicated they were more aware of their daily PA levels and 68 % ( 28/41 ) found the site easily navigable . Adjusted group differences in total exercise minutes favored the UCAN group by an increase of 42 minutes ( 95 % CI -65 to 150 ; P=.44 , d=0.17 ) . Results were more pronounced , though still nonsignificant , among those not meeting guidelines at baseline where UCAN increased PA by 52 minutes compared to a decrease of 15 minutes in UC ( adjusted between group difference=75 , 95 % CI -95 to 244 ; P=.38 , d=0.27 ) . Conclusions We found that Internet-delivery may be a feasible alternative to more costly methods to promote PA among Nova Scotian cancer survivors . Moreover , there was a trend toward increased PA among those in the UCAN group , especially among those who were not meeting PA guidelines at baseline . Future research should focus on recruiting inactive cancer survivors and engaging them in the website to determine the optimal potential of Web-based interventions for promoting PA in cancer survivors Background Oral chemotherapy is increasingly used in place of traditional intravenous chemotherapy to treat patients with cancer . While oral chemotherapy includes benefits such as ease of administration , convenience , and minimization of invasive infusions , patients receive less oversight , support , and symptom monitoring from clinicians . Additionally , adherence is a well-documented challenge for patients with cancer prescribed oral chemotherapy regimens . With the ever-growing presence of smartphones and potential for efficacious behavioral intervention technology , we created a mobile health intervention for medication and symptom management . Objective The objective of this study was to develop and evaluate the usability and acceptability of a smartphone app  to support adherence to oral chemotherapy and symptom management in patients with cancer . Methods We used a 5-step development model to create a comprehensive mobile app with theoretically informed content . The research and technical development team worked together to develop and iteratively test the app . In addition to the research team , key stakeholders including patients and family members , oncology clinicians , health care representatives , and practice administrators contributed to the content refinement of the intervention . Patient and family members also participated in alpha and beta testing of the final prototype to assess usability and acceptability before we began the r and omized controlled trial . Results We incorporated app components based on the stakeholder feedback we received in focus groups and alpha and beta testing . App components included  medication reminders , self-reporting of medication adherence and symptoms , an education 
    Output:
    
Results from the studies showed a high level of engagement .
Self-efficacy , psychological symptoms , and quality of life were the most commonly assessed psychosocial variables .
The present review showed that despite the heterogeneity in the studies assessed and inconsistent results , DI may constitute an excellent means to help cancer patients and survivors cope better with the disease and with treatment side effects , as they can improve self-management and wellbeing .
