Decision-making in rectal and colorectal cancer: systematic review and qualitative analysis of surgeons’ preferences

Surgeons are experiencing difficulties implementing recommendations not only owing to incomplete, confusing or conflicting information but also to the increasing involvement of patients in decisions relating to their health. This study sought to establish which common factors including heuristic factors guide surgeons’ decision-making in colon and rectal cancers. We conducted a systematic literature review of surgeons’ decision-making factors related to colon and rectal cancer treatment. Eleven of 349 identified publications were eligible for data analyses. Using the IRaMuTeQ (Interface of R for the Multidimensional Analyses of Texts and Questionnaire), we carried out a qualitative analysis of the significant factors collected in the studies reviewed. Several validation procedures were applied to control the robustness of the findings. Five categories of factors (i.e. patient, surgeon, treatment, tumor and organizational cues) were found to influence surgeons’ decision-making. Specifically, all decision criteria including biomedical (e.g. tumor information) and heuristic (e.g. surgeons’ dispositional factors) criteria converged towards the factor ‘age of patient’ in the similarity analysis. In the light of the results, we propose an explanatory model showing the impact of heuristic criteria on medical issues (i.e. diagnosis, prognosis, treatment features, etc.) and thus on decision-making. Finally, the psychosocial complexity involved in decision-making is discussed and a medico-psycho-social grid for use in multidisciplinary meetings is proposed.     

Virtual voices: social support and stigma in postnatal mental illness Internet forums

Many women with postnatal mental illness do not get the treatment they need and this is often because stigma prevents disclosure. The purpose of this study was to explore online social support for postnatal mental illness, how women experience stigma and potential disadvantages of using Internet forums. Interviews were conducted with fifteen participants who had suffered postnatal mental illness and had used forums. Systematic thematic analysis identified common themes in relation to social support, stigma and disadvantages of using forums. Most women felt they benefited from visiting forums by developing a shared understanding and discourse about their illness. Findings suggest future research should investigate if women benefit from using online social support provided by forums, if use challenges stigma and further explore potential concerns about using forums.     

Exploring rates of transgender individuals and mental health concerns in an online sample

Background: Prevalence estimates of adults identifying as transgender are scarce, particularly in the United States. Method: The current study endeavored to estimate the prevalence of individuals identifying as transgender in a large online sample of adult U.S. residents (n = 6,727) and compare the prevalence of common mental health disorders (depression, anxiety, attention-deficit/hyperactivity disorder) and the age of onset for individuals identifying as men or women versus those identifying as transgender. Results: The prevalence estimate of individuals identifying as transgender was 0.8%. Individuals identifying as transgender were significantly more likely than individuals identifying as men or women to report having had a single diagnosis or co-occurring diagnoses for all three disorders examined. Additionally, transgender individuals were more likely than individuals identifying as men or women to receive a diagnosis of anxiety or depression at a younger age. Conclusion: Given the prevalence of transgender individuals and the associations with common mental health conditions, clinicians must be informed and competent to care for their clinical needs. This study introduces online crowdsourcing resources as a potentially fruitful option for reaching and researching gender diversity.

Developing new online calibration methods for multidimensional computerized adaptive testing

Multidimensional computerized adaptive testing (MCAT) has received increasing attention over the past few years in educational measurement. Like all other formats of CAT, item replenishment is an essential part of MCAT for its item bank maintenance and management, which governs retiring overexposed or obsolete items over time and replacing them with new ones. Moreover, calibration precision of the new items will directly affect the estimation accuracy of examinees’ ability vectors. In unidimensional CAT (UCAT) and cognitive diagnostic CAT, online calibration techniques have been developed to effectively calibrate new items. However, there has been very little discussion of online calibration in MCAT in the literature. Thus, this paper proposes new online calibration methods for MCAT based upon some popular methods used in UCAT. Three representative methods, Method A, the ‘one EM cycle’ method and the ‘multiple EM cycles’ method, are generalized to MCAT. Three simulation studies were conducted to compare the three new methods by manipulating three factors (test length, item bank design, and level of correlation between coordinate dimensions). The results showed that all the new methods were able to recover the item parameters accurately, and the adaptive online calibration designs showed some improvements compared to the random design under most conditions.

Scientific Peer Review: A Case Study From Local And Global Analyses.

The dialog between Staddon (2001, 2004) and Baum (2004) raises general questions about the nature of scientific peer review. Their dialog displays effects on peer review of differences of opinion about the relative merits of local and global analyses. Baum (1995, 1997, 2001, 2002) favors global analyses as a paradigm different, newer, and better than the local, dynamic, real‐time approach that plays a significant role in Staddon (2001). According to the Kuhnian perspective (Kuhn, 1996) Baum advocates, we can better understand his review of Staddon (2001) by considering the implications for it of his commitment to the idea that a global analysis is a superior scientific paradigm. This commentary examines some characteristics of local and global analyses, as well as some of their possible implications for peer review in the context of a reviewer's belief in the Kuhnian idea of incommensurability: According to this idea, a reviewer who either is, or who believes he is, from one paradigm is unlikely, for better or worse, to understand or perhaps even tolerate work from a different paradigm. It is recommended that a process be developed to encourage “truth in peer reviewing” to reduce possible conflicts of interest embedded in the current conception of scientific peer review.     

Clinical and demographic features of the online counselling client population

The purpose of this research was to determine the demographics and characteristics of clients seeking online counselling over an eight‐month period of clinical online practice. Two hundred and seventeen clients seeking Internet counselling completed a Counselling Application and a Life History Questionnaire. The characteristics of the relatively new client population include the following categories: gender, age groups, martial status, education, primary reason for seeking online therapy, secondary issues, frequency of email exchanges, and online vs. face‐to‐face counselling preferences. Implications for online counselling practice are discussed.
