Single-case design emphasis in American Psychological Association-accredited school psychology programs.

Single-case design (SCD) is an underutilized research methodology in school psychology literature. Despite its relevance to practitioners and applied intervention researchers alike, the majority of intervention research disseminated in school psychology journals tends to involve group designs, such as the randomized controlled trial. Group designs are useful for answering a wide variety of research questions but may not always be relevant to practitioners seeking procedures that work for their students or researchers seeking for the optimal design to answer their research questions. In comparison, the relative dearth of SCD studies in school psychology literature, in conjunction with common values among the field regarding data-based decision making and the scientist-practitioner model to training, raises questions about the cause of this gap. The present study sought to review doctoral training programs in school psychology and evaluate their relative emphasis on SCD in training. Seventy-six American Psychological Association-accredited school psychology programs were reviewed, and results indicated that roughly two thirds of programs do not emphasize SCD during training. Implications regarding school psychology training and research are discussed and recommendations are provided on future directions for school psychology trainers and researchers.

The Effects of an Inclusive Badminton Program on Static Postural Control for Individuals with Intellectual and Developmental Disabilities.

The purpose of the study was to examine static postural control/balance in young adults with intellectual and developmental disabilities (IDD) and typically developing (TD) young adults before, during, and after an inclusive badminton intervention. Eight participants (four IDD-BADM and four TD-BADM) participated in a 12-week inclusive badminton intervention, with the other eight participants as matched controls (four IDD-CONTR and four TD-CONTR) (74.19 kg ± 9.8 kg, 171.96 cm ± 5.4 cm; 21.7 ± 1.8 years of age; nine females and seven males; eight with IDD and eight TD). The study followed a repeated measures design (pre, mid, post) before the intervention, at 6 weeks, and after 12 weeks. Static postural sway conditions included: bilateral stance eyes open (20 s), eyes closed (10 s), foam eyes open (20 s), foam eyes closed (10 s), and unilateral stance eyes open (10 s) and foam eyes open (10 s). Sway measurements included: average anterior/posterior (A/P) displacement (in), average medial/lateral (M/L) displacement (in), average 95% ellipsoid area (in2), and average velocity (ft/s). Significant time × group interactions were reported for average velocity (EO) (p = 0.030), average length (EO) (p = 0.030), 95% ellipsoid area (EO) (p = 0.049), and average A/P displacement (1LEO) (p = 0.036) for IDD-BADM. Significant time main effects were reported for average A/P displacement (FEO) (p = 0.040) for IDD groups. Significant time main effects were reported for average M/L displacement (EO) (p = 0.001), (EC) (p = 0.004), (FEO) (p = 0.005), (FEC) (p = 0.004), and average A/P displacement (EO) (p = 0.006) and (FEO) (p = 0.005) for TD groups. An inclusive badminton program indicated evidence of improved static postural control for those with IDD. However, no significant differences were reported for TD peers.
