Comparison studies conducted to determine which instructional interventions are most efficient for teaching discrete behaviors to individuals with disabilities are potentially valuable, although some threats to internal validity may be more likely in these studies. Studies included in this review typically met common internal validity standards, such as reliability measurement, but often did not include controls specific to comparison designs. Comparisons often included young children with autism and were frequently conducted by researchers in self-contained classroom settings. Systematic instruction was effective in nearly all comparisons, although many included undifferentiated data (i.e., both interventions were equally effective), and within-participant replications were often inconsistent (i.e., outcomes varied across comparisons for a single participant). Results suggest implementers should conduct high-fidelity instruction with corrective and instructive feedback and should choose intervention variations based on participant preference. We recommend researchers include control sets or time-lagged introductions, counterbalance behavior sets, and measure differential acquisition over time.

Antecedent interventions are often used preventatively to address engagement, but few studies have evaluated their effectiveness with students at risk for disability. This study evaluated the effectiveness of two commonly recommended antecedent interventions that have limited empirical support for use with students at risk: social stories and visual supports. Both interventions were evaluated separately in the context of two single-case alternating treatments designs across five elementary students at risk for emotional and behavioral disorders. Social stories were not effective for improving students’ levels of engagement during targeted activities; visual supports resulted in increases in students’ engagement relative to baseline conditions. Future use of visual supports for students at risk should include evaluations of the feasibility of implementation by teaching staff.

(DERS). Results:The DERS scores among these two groups were not significantly different before the treatment. Statistical analysis showed that both online and live DBT significantly reduced DERS scores in all 6 categories and there was no significant differences in amount of the changes in the scores in the 2 groups. Conclusion: Despite the proven efficacy of psychotherapy, there are some barriers, including being resistant to taking part in live sessions, long wait-lists and transportation. With Internet use rising, delivering online psychotherapy might be an alternative method.
