Understanding Cancer Worry Among Patients in a Community Clinic-Based Colorectal Cancer Screening Intervention Study

Methodological Quality of PROMs in Psychosocial Consequences of Colorectal Cancer Screening: A Systematic Review

Objective

This systematic review aimed to assess the adequacy of measurement properties in Patient-Reported Outcome Measures (PROMs) used to quantify psychosocial consequences of colorectal cancer screening among adults at average risk.

Methods

We searched four databases for eligible studies: MEDLINE, CINAHL, PsycINFO, and Embase. Our approach was inclusive and encompassed all empirical studies that quantified aspects of psychosocial consequences of colorectal cancer screening. We assessed the adequacy of PROM development and measurement properties for content validity using The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) risk of bias checklist.

Results

We included 33 studies that all together used 30 different outcome measures. Two PROMs (6.7%) were developed in a colorectal cancer screening context. COSMIN rating for PROM development was inadequate for 29 out of 30 PROMs (97%). PROMs lacked proper cognitive interviews and pilot studies and therefore had no proven content validity. According to the COSMIN checklist, 27 out of 30 PROMs (90%) had inadequate measurement properties for content validity.

Discussion

The majority of included PROMs had inadequate development and measurement properties. These findings shed light on the trustworthiness of the included studies' findings and call for reevaluation of existing evidence on the psychosocial consequences of colorectal cancer screening. To provide trustworthy evidence about the psychosocial consequences of colorectal cancer screening, editors could require that studies provide evidence of the methodological quality of the PROM. Alternatively, authors should transparently disclose their studies' methodological limitations in measuring psychosocial consequences of screening validly.

Self-Reported Reasons for Inconsistent Participation in Colorectal Cancer Screening Using FIT in Flanders, Belgium

Background: In Flanders, the uptake in the population-based colorectal cancer (CRC) screening program (using fecal immunochemical test, FIT) is suboptimal (~50%). This study explored the reasons for inconsistent participation in FIT screening among irregular participants in Flanders. Methods: An online survey with both open questions and fixed statements was sent to irregular participants (2016–2018) in the Flemish CRC screening program. A reminder email followed eight weeks after the first email. Data analysis used both qualitative and quantitative approaches. Post-stratification weights based on gender, age group, and the first two digits of the postcode were employed to reduce non-response bias. Results: In total, 5328 out of 19,592 irregular participants responded to the survey. While the main reasons not to participate were related to ‘postponing participation’ and ‘having other priorities’, the main reasons to participate were related to the importance of (preventive) health checks. The role of general practitioners (GPs) in promoting CRC screening also emerged as an important theme among the respondents’ answers (based on fixed statements). Conclusions: The study reported the main reasons for inconsistent participation in FIT screening for CRC in Flanders. The findings are helpful in guiding tailored interventions to increase FIT screening uptake in the region.

Online Health Information Seeking and eHealth Literacy Among Spanish Language-Dominant Latino Adults Receiving Care in a Community Clinic: Secondary Analysis of Pilot Randomized Controlled Trial Data

BACKGROUND

eHealth literacy is the ability to seek, obtain, and decipher online health information (OHI) for health and disease management. Rapid developments in eHealth (eg, health care services and online information) place increased demands on patients to have high eHealth literacy levels. Yet, greater emphasis on eHealth may disproportionately affect groups with limited eHealth literacy. Cultural background, language, and eHealth literacy are influential considerations affecting health care and information access, health care use, and successful eHealth resource use, and they may influence OHI seeking for behavioral change toward cancer prevention.

OBJECTIVE

This study aimed to characterize the extent of OHI seeking and eHealth literacy among Spanish-dominant (SD) Latino adults aged 50 to 75 years. Further, we aimed to examine potential associations between sociodemographic characteristics, Preventive Health Model (PHM) constructs, OHI-seeking behaviors, and eHealth literacy, separately.

METHODS

Participants (N=76) self-identified as Latino, were enrolled in a colorectal cancer (CRC) screening intervention, were aged 50 to 75 years, were at average risk for CRC, were not up to date with CRC screening, and preferred receiving health information in Spanish. We describe participants' sociodemographic characteristics, PHM constructs, OHI-seeking behaviors, and eHealth literacy-among those seeking OHI-assessed at enrollment. Descriptive analyses were first performed for all variables. Next, primary univariate logistic analyses explored possible associations with OHI seeking. Finally, using data from those seeking OHI, exploratory univariate analyses sought possible associations with eHealth literacy.

RESULTS

A majority (51/76, 67%) of the participants were female, 62% (47/76) reported not having graduated high school, and 41% (31/76) reported being unemployed or having an annual income of less than US $10,000. Additionally, 75% (57/76) of the participants reported not having health insurance. In total, 71% (54/76) of the participants reported not having sought OHI for themselves or others. Univariate logistic regression suggested that higher educational attainment was significantly associated with an increased likelihood of having sought OHI (odds ratio 17.4, 95% CI 2.0-150.7; P=.009). Among those seeking OHI (22/76, 29%), 27% (6/22) were at risk of having low eHealth literacy based on an eHealth Literacy Scale score of less than 26. Among OHI seekers (22/76, 29%), an examination of associations found that higher eHealth literacy was associated with greater self-efficacy for screening with the fecal immunochemical test (β=1.20, 95% CI 0.14-2.26; P=.02).

CONCLUSIONS

Most SD Latino participants had not sought OHI for themselves or others (eg, family or friends), thus potentially limiting access to beneficial online resources. Preliminary findings convey that higher eHealth literacy occurs among those with higher self-efficacy for CRC screening. Findings inform areas of focus for future larger-scale investigations, including further exploration of reasons for not seeking OHI among SD Latino adults and an in-depth look at eHealth literacy and cancer screening behaviors.
