Peer Feedback: Recommendations for Behavior Analysts' Training and Supervision

The increase in demand for behavior analysts in recent years has also increased the importance of effective supervision practices in the field of behavior analysis. A critical supervisory skill is performance feedback, which entails proficiency with two distinct, yet inseparable repertoires of technical and nontechnical skills. Supervisors report never receiving explicit training in feedback (Sellers et al., 2019) and graduate training programs provide little to no training in nontechnical skills (LeBlanc, Taylor et al., 2020b; Pastrana et al., 2018). As with any skill, to develop proficiency with feedback delivery and reception, trainees may require ample practice opportunities. One mechanism to provide trainees routine practice opportunities is to use peers as behavior change agents and peer feedback as an instructional method. The utility of peer feedback has been recognized in the organizational behavior management (OBM) literature (e.g., behavior-based safety interventions; Lebbon et al., 2012; Wirth & Sigurdsson, 2008), and has been used successfully in medical student training and evaluation for several decades. In the context of behavior analytic training and supervision peer feedback has yet to be established as a training method. Similarities in the behavioral and medical fields (e.g., significance of professional and interpersonal skills for successful therapeutic relationships) make the medical field a good model from which behavior analysts can learn. Using peer feedback in training and supervision for behavior analysts may provide trainees with similar benefits to those reported in medical student training literature.

Fighting colorectal cancer: molecular epidemiology differences among Ashkenazi and Sephardic Jews and Palestinians

BACKGROUND

To evaluate and compare differences in the molecular genetics among high-risk (Ashkenazi Jews), intermediate-risk (Sephardic Jews) and low-risk (Palestinians) groups for colorectal cancer who live in the same geographical region.

PATIENTS AND METHODS

The 1995-1996 records from the Tel Aviv Medical Center and Muqased hospital (East Jerusalem) randomly identified patients with colorectal cancer. There were 25 patients from each ethnic group. Epidemiological data were obtained from interviews with the patients and from their hospital charts. The levels of cyclin D1, beta-catenine, p27, p53, Ki-67 and Her-2/neu proteins were determined by immunohistochemistry. The main outcome measures were the association between gene expression and colorectal incidence in the different ethnic groups.

RESULTS

Ashkenazi Jews have the highest rate of colorectal cancer, and are diagnosed at an early stage compared with Palestinians (72% and 33% of the cases are in Dukes' A and B, respectively), and, hence, this may explain the better 5-year survival rate among this group. Sephardic Jews are diagnosed at a more advanced stage, the tumors are poorly differentiated and they lack p27. Palestinians have significantly higher cyclin D1 levels. There was a statistically significant inverse correlation between the expression of beta-catenine and cyclin D1, as well as p53 and p27 (P <0.05).

CONCLUSIONS

Increased expression of cyclin D1, p53, Ki-67, beta-catenine and Her-2/neu, and decreased expression of p27 may be important events in the three ethnic groups with colorectal cancer. The lower mortality rate among Ashkenazi Jews may be partially explained by their better molecular biology profile.
