Using an Internet-Based Breast Cancer Risk Assessment Tool to Improve Social-Cognitive Precursors of Physical Activity.

ABSTRACT: BACKGROUND:Internet-based cancer risk assessment tools might serve as a strategy for translating epidemiological risk prediction research into public health practice. Understanding how such tools affect key social-cognitive precursors of behavior change is crucial for leveraging their potential into effective interventions. PURPOSE:To test the effects of a publicly available, Internet-based, breast cancer risk assessment tool on social-cognitive precursors of physical activity. METHODS:Women (N = 132) aged 40-78 with no personal cancer history indicated their perceived risk of breast cancer and were randomly assigned to receive personalized ( www.yourdiseaserisk.wustl.edu ) or nonpersonalized breast cancer risk information. Immediately thereafter, breast cancer risk perceptions and physical activity-related behavioral intentions, self-efficacy, and response efficacy were assessed. RESULTS:Personalized information elicited higher intentions, self-efficacy, and response efficacy than nonpersonalized information, P values < 0.05. Self-efficacy and response efficacy mediated the effect of personalizing information on intentions. Women who received personalized information corrected their inaccurate risk perceptions to some extent, P values < 0.05, but few fully accepted the information. CONCLUSION:Internet-based risk assessment tools can produce beneficial effects on important social-cognitive precursors of behavior change, but lingering skepticism, possibly due to defensive processing, needs to be addressed before the effects can be maximized.

Project description:BackgroundPersistent cognitive impairment is prevalent in unipolar and bipolar disorders and is associated with decreased quality of life and psychosocial dysfunction. The screen for cognitive impairment in psychiatry (SCIP) test is a validated paper-and-pencil instrument for the assessment of cognition in affective disorders. However, there is no digital cognitive screening tool for the brief and accurate assessment of cognitive impairments in this patient group.ObjectiveIn this paper, we present the design process and feasibility study of the internet-based cognitive assessment tool (ICAT) that is designed based on the cognitive tasks of the SCIP. The aims of this feasibility study were to perform the following tasks among healthy individuals: (1) evaluate the usability of the ICAT, (2) investigate the feasibility of the ICAT as a patient-administered cognitive assessment tool, and (3) examine the performance of automatic speech recognition (ASR) for the assessment of verbal recall.MethodsThe ICAT was developed in a user-centered design process. The cognitive measures of the ICAT were immediate and delayed recall, working memory, and psychomotor speed. Usability and feasibility studies were conducted separately with 2 groups of healthy individuals (N=21 and N=19, respectively). ICAT tests were available in the English and Danish languages. The participants were asked to fill in the post study system usability questionnaire (PSSUQ) upon completing the ICAT test. Verbal recall in the ICAT was assessed using ASR, and the performance evaluation criterion was word error rate (WER). A Pearson 2-tailed correlation analysis significant at the .05 level was applied to investigate the association between the SCIP and ICAT scores.ResultsThe overall psychometric factors of PSSUQ for both studies gave scores above 4 (out of 5). The analysis of the feasibility study revealed a moderate to strong correlation between the total scores of the SCIP and ICAT (r=0.63; P=.009). There were also moderate to strong correlations between the SCIP and ICAT subtests for immediate verbal recall (r=0.67; P=.002) and psychomotor speed (r=0.71; P=.001). The associations between the respective subtests for working memory, executive function, and delayed recall, however, were not statistically significant. The corresponding WER for English and Danish responses were 17.8% and 6.3%, respectively.ConclusionsThe ICAT is the first digital screening instrument modified from the SCIP using Web-based technology and ASR. There was good accuracy of the ASR for verbal memory assessment. The moderate correlation between the ICAT and SCIP scores suggests that the ICAT is a valid tool for assessing cognition, although this should be confirmed in a larger study with greater statistical power. Taken together, the ICAT seems to be a valid Web-based cognitive assessment tool that, after some minor modifications and further validation, may be used to screen for cognitive impairment in clinical settings.

Project description:ImportanceThe increasing prevalence of cognitive decline, impairment, and dementia spurs intense interest in cognitive preservation strategies.ObjectiveTo explore the longitudinal association between physical activity (PA) and cognitive performance among women at midlife.Design, setting, and participantsThis cohort study is an analysis from the Study of Women's Health Across the Nation. Enrollment occurred from 1996 through 1997, and follow-up extended into 2017. Included individuals were those who had undergone cognitive measures during the first 3 cognitive test visits and had at least 1 additional cognitive measurement. Stroke prior to baseline was an exclusion, and observations were censored for subsequent stroke. Data were analyzed from June 2018 through August 2019.ExposuresEngaging in sport or exercise PA (self-reported).Main outcomes and measuresThe Symbol Digit Modalities Test (SDMT) was used to assess cognitive processing speed. The East Boston Memory Test-Delayed (EBMT-D) was used to measure verbal episodic memory. The digit span backwards (DSB) test was used to evaluate working memory.ResultsAmong 1718 women with a median (range) observation time of 11.9 (0.60-13.5) years, the mean (SD) baseline age was 45.7 (2.5) years. From baseline through age 61 years, mean change in SDMT score was -0.20 annually (95% CI, -0.26 to -0.15; P < .001). After age 61 years, the mean change in SDMT was -0.51 yearly (95% CI, -0.54 to -0.41; P < .001). Beginning at age 58 years of the mean change in EBMT was -0.03 yearly (95% CI, -0.04 to -0.02; P < .001). Starting at age 61 years, mean (SD) change in DSB was -0.03 annually (95% CI, -0.04 to -0.01; P = .001). When adjusted for attrition and practice effect, PA was associated with higher concurrent SDMT and EBMT scores and a smaller decrease in SDMT score. For each unit increment in PA, there was a 0.36 increment in concurrent SDMT score (95% CI, 0.14 to 0.59; P = .002) and a 0.10 increment in concurrent EBMT score (95% CI, 0.05 to 0.15; P < .001). Greater PA was associated with a smaller annual mean decrease in SDMT score (0.06 yearly; 95% CI, 0.02 to 0.09; P = .001). After additional adjustment for demographic characteristics, menopause symptoms, hormone therapy use, and the presence of diabetes and hypertension, PA was not associated with trajectories (ie, levels or slopes) of any cognitive outcome.Conclusions and relevanceThis cohort study found no association between greater PA levels and cognitive outcomes among women in midlife, unlike cohort studies that begin observations at later ages, which may be associated with confounding by reverse causation (ie, cognitive decline associated with an outcome of lower PA levels).

Project description:Interventions: The intervention arm is named HoPS, an acronym of Home-based Physical Activity for Survivors. HoPS intervention programme aims to improve physical activity level among cancer survivors, in particular breast and colorectal cancer by employing Social Cognitive Theory (SCT) in the development of the programme. It combines of psychoeducation and social media approach to behavioural intervention. Participants of the HoPS will be provided with a non-tailored printed material and gradual tapering down of face-to-face group meetings to improve knowledge and skills of physical activity. While WhatsApp is used as a structured direct remote feedback strategy to allow for supervised home-based physical activity. 1. Face-to-face group meetings There will be 2 meet up sessions for all participants in the HoPS group. The sessions provide a standardized lectures deliver by the researcher using power point slides. The first session of lecture (1-hour duration) will cover the areas of a brief introduction of HoPS programme, physical activity knowledge and goal setting. The second session of lecture (15-minutes duration) will cover for barriers to physical activity and following that a sharing session (15-minutes duration) by a role model (a cancer survivor) to share her experience in engaging in physical activity. In each of the sessions, after the lectures, an exercise session will be conducted by a certified exercise instructor with at least 3 years experienced in coaching for exercise. The duration of this exercise session will be 2 hours and the focus is train the participants on how to perform a proper and correct exercise for cancer survivors. This will involved aerobic exercises and resistance exercis Primary outcome(s): Total MET-minutes/week using validated IPAQ [Baseline, at 8-week (immediately after intervention) and at 16-week post intervention] Study Design: Purpose: Educational / counselling / training; Allocation: Randomised controlled trial; Masking: Blinded (masking used);Assignment: Parallel;Type of endpoint: Efficacy
