“…The CCSBS was developed using rigorous methods [24][25][26][27] and this study evaluated the included scales for future use in survey research on CRC screening with SA populations. The results of pilot testing demonstrated good feasibility for recruitment, interviewer-led administration, and data collection with improved tablet functionality.…”

“…The concerns raised by Site A participants regarding number of response categories was important because in prior work, a 5-point Likert scale was used [26,27]. The decision to change to a 7-point Likert scale occurred because we wanted to have greater discriminative power [43].…”

“…This pilot study assessed psychometric properties of the developed scales to verify findings from prior studies [24][25][26][27]. The final survey was reduced to 4 scales and 34 items: perceived susceptibility, perceived severity, perceived barriers (home stool test and colonoscopy), and subjective norm.…”

“…A priori sample size was determined to assess psychometric properties of scales by examining the ratio of participants to parameter to be estimated for a 60-item factor analysis [31], resulting in a sample size of 300. Given that prior cognitive testing was performed [27], we believed items were conceptually consistent across Urdu and English language surveys; thus, this sampling frame was satisfactory to meet study objectives.…”

“…The purpose of the survey is to describe or predict CRC screening that influences uptake among SAs. The CCSBS was cross-culturally adapted into the Urdu language and its cognitive testing demonstrated good content validity [27]. The primary objective of the current study is to evaluate feasibility of survey administration, data collection using computer assisted personal interviewing (CAPI) software, and response burden; and the secondary objectives are to examine psychometric properties of sub-scales along with prevalence of CRC screening among SAs in Ontario, Canada.…”

Purpose: The purpose of the study was to pilot test the English and Urdu version of the Colon Cancer Screening Behaviours Survey among South Asians in Canada. The first objective was to evaluate feasibility of administration, data collection using computer assisted personal interviewing software on a tablet, and response burden. The second objective was to examine the prevalence of colorectal cancer screening among South Asians and evaluate the psychometric properties of sub-scales in the survey. Methods: Purposive, network and snowball sampling were used to recruit participants for this cross-sectional study. Interviewer-led administration of the Colon Cancer Screening Behaviours Survey was conducted across two cities in Ontario, Canada. Qualitative data analysis assessed feasibility; and sub-scales were evaluated through principal component analysis, item-scale correlations, and construct validity using multiple linear and logistic regression. Results: A total of 328 South Asians participated, 47% Urdu speaking, and 53% English speaking. There was a 23% refusal rate to participate. Feasibility identified: (1) successful recruitment despite reasons for refusal; (2) problematic items and response categories; and (3) computer/tablet limitations. Principal component analysis identified 14 components that explained 68.7% of total variance; 34 items were retained after factor analysis. Internal consistency of 4 scales ranged from 0.79-0.91. There were significant differences in perceived barriers scale scores (− 12.21; 95% CI, − 17.13 to-7.28; p < 0.0001) between those who participated and those who did not participate in screening. No association was found with years of residence and uptake of screening after adjustment (OR 0.91 (0.46-1.79), p = 0.783). Conclusions: Recruitment and data collection methods are feasible among South Asians if functionality of the tablet selected is improved. The Colon Cancer Screening Behaviours Survey was finalized and retained items in subscales demonstrated good psychometric properties to assess behaviours for colon cancer screening among South Asians in Canada. The interviewer-led survey may be used by public health, cancer care or other health practitioners to describe or predict colorectal cancer screening behaviours among South Asians in similar settings or adapted and tested in other contexts.

Purpose While there is literature that examines factors associated with low participation in cancer screening among Canadian ethnic groups, there is limited understanding of black visible minorities, particularly Somalis. Thus, the purpose of this study is to synthesize knowledge pertaining to the perceptions, beliefs and barriers of Somali women and men toward screening for breast, cervical and colorectal cancers in countries such as Canada. Design/methodology/approach The scoping review methodology was used to search for peer-reviewed articles that explicitly examined perceptions, beliefs and barriers among Somalis toward screening for breast, cervical and colorectal cancers in developed countries. The following electronic databases were searched without time frame restrictions, namely, OVID Medline, Embase, CINHAL, PubMed, Scopes and ProQuest. A total of 402 peer-reviewed articles were identified and screened. Three articles were identified through reference list screening (one eligible) and consultation with experts in the networks (two eligible). In total, 12 studies met the inclusion criteria for synthesis. Thematic analysis was used to analyze the selected articles for key themes and the synthesis was informed by the socio-ecological model. Findings The majority of studies originated from the USA and focused primarily on Somali women and cervical cancer screening. Themes that emerged from the literature include individual-level negative experiences and socio-cultural perceptions/beliefs; community-level barriers in cancer screening; and systemic challenges in navigating the health-care system. Many of the studies focused on individual and community-level determinants of cancer screening, with little attention to systemic level determinants. Other gaps identified include factors influencing Somali men’s low participation in cancer screening; limited studies on colorectal cancer and Somali women; and specific cancer-screening barriers faced by Somalis within the Canadian context. Originality/value The findings of the review reveal multiple cancer screening challenges for Somali communities and the gained insights should inform both health and social care practitioners and policymakers.

Cross-cultural survey development: The Colon Cancer Screening Behaviors Survey for South Asian populations

ObjectiveThe objective of this work was to develop a survey that considered cultural relevance and diversity of South Asian populations, with the aim of describing or predicting factors that influence colorectal cancer screening intention and adherence. The scientifically rigorous approach for survey development informed the final phase of an exploratory mixed method study. This initial survey was later cross-culturally translated and adapted into the Urdu language, and thereafter, items were cognitively tested for conceptual relevance among South Asian immigrants.ResultsThe initial development of the Colon Cancer Screening Behaviours Survey for South Asian populations was completed using a number of steps. Development involved: the identification of key concepts and conceptual model; literature search for candidate measures and critical appraisal; and, expert consultation to select relevant measures. Five published surveys included measures that covered concepts relevant to South Asians and colorectal cancer screening behaviours. However, measures from these surveys missed content that emerged through parallel field work with South Asians, and additions were required along with item modifications. In the final stage, cross-cultural translation and adaptation into Urdu, and cognitive testing were completed. Future research will require an examination of proposed relationships, and psychometric testing of measures in the survey.Electronic supplementary materialThe online version of this article (10.1186/s13104-017-3098-3) contains supplementary material, which is available to authorized users.
