The Effect of Self-Determination Activities on Communication and Interaction Skills and Academic Success (Grade Point Average) of Students at Risk of Emotional-Behavioral Disorders: A Randomized Controlled Trial.

Background: Students with emotional and behavioral disorders (EBD) have lower academic efficiency than students with other disabilities and exhibit high levels of problematic behaviors and low levels of social functioning. This research aims to investigate the impact of self-determination activities on communication skills and scholastic achievement of students at risk of emotional-behavioral disorders. Methods: The study was conducted through a randomized controlled trial during the academic year 2018-2019. The samples included 54 female students (14 to 16 years) at risk of emotional-behavioral disorders from secondary schools in Tehran, Iran. The sampling was conducted through a random cluster method. The applied tools encompass Youth Self-report and Assessment of Communication and Interaction Skills. Academic success was measured by students' grade point average (GPA) in two terms. The intervention was held in 8 sessions of 90 minutes, once a week, after the first term of academic of students for the intervention group and the control group did not receive any intervention during this period. The data were analyzed by SPSS-22, MANCOVA, T-test, and Chi-Square tests. Results: The results of the multivariate analysis of covariance analysis showed self-determination has an impact on communication skills (physicality, information exchange and relations) of students at risk of emotional-behavioral disorders (p<0.05). Comparing the difference between the averages of the two students' means, it was found that there was a significant difference in the two groups after the intervention (p<0.001). Also, after the intervention, there was no significant difference between the two groups but the GPA of students in the intervention group increased from 13.19 to 15.61. Conclusion: The findings suggested self-determination is effective for academic success and communication skills of students at risk of emotional-behavioral disorders and can be used in educational programs for these students.

Effect of occupational therapy on self-determination skills of adolescents at risk of emotional and behavioral disorders: A randomized controlled trial.

Background: Self-determination skills enable to support an individual's needs and make decisions to function independently. Improvement of self-determination skills has had a positive result for adolescents at risk of Emotional and Behavioral Disorders (EBD). The aim of this study was to investigate the effect of occupational therapy interventions on the self-determination skills of adolescent girls at risk of emotional-behavioral disorders. Methods: In this single-blind control trial study, 14-16-years-old girl students (n=54) at risk of EBD were recruited by cluster sampling from secondary high schools of Tehran, Iran. Youth self-report Questionnaire (YSR) was used to include adolescents at risk of EBD in the study and were randomized into the intervention (n=27) and control group (n=27) by block randomization. The Student Self-Determination Scale (SDSS) and the Self-determination Parent Perception Scale (SDPPS) were used to collect data. Students in the intervention group participated in 8 - once a week- sessions of occupational therapy and the control group received no training. Data were analyzed by repeated-measures analysis of variance (RMANOVA), Bonferroni test and SPSS 16.0 version. The significance level was set at 0.05. Results: The score of self-determinations (SDSS) increased significantly in the intervention group after the intervention (p<0.001). Although the mean scores of self-determination at follow-up have increased in the intervention group compared to the post-test. No significant differences were found (p>0.05); also, the score of parents' perception of student self-determination (SDPPS) increased but there were not significantly different (p=0.064). Conclusion: The findings indicated self-determination skills could be taught to adolescents at risk of EBD in OT sessions. Since self-determination has been identified as the necessary skills for adolescents at-risk to transition into adulthood, occupational therapists have an important role in promoting self-determination skills in adolescents at risk of EBD.

Test-Retest Reliability and Minimal Detectable Change of Randomized Dichotic Digits in Learning-Disabled Children: Implications for Dichotic Listening Training.

BACKGROUND: Evaluation of dichotic listening to digits is a common part of many studies for diagnosis and managing auditory processing disorders in children. Previous researchers have verified test-retest relative reliability of dichotic digits results in normal children and adults. However, detecting intervention-related changes in the ear scores after dichotic listening training requires information regarding trial-to-trial typical variation of individual ear scores that is estimated using indices of absolute reliability. Previous studies have not addressed absolute reliability of dichotic listening results. PURPOSE: To compare the results of the Persian randomized dichotic digits test (PRDDT) and its relative and absolute indices of reliability between typical achieving (TA) and learning-disabled (LD) children. RESEARCH DESIGN: A repeated measures observational study. STUDY SAMPLE: Fifteen LD children were recruited from a previously performed study with age range of 7-12 yr. The control group consisted of 15 TA schoolchildren with age range of 8-11 yr. DATA COLLECTION AND ANALYSIS: The Persian randomized dichotic digits test was administered on the children under free recall condition in two test sessions 7-12 days apart. We compared the average of the ear scores and ear advantage between TA and LD children. Relative indices of reliability included Pearson's correlation and intraclass correlation (ICC2,1) coefficients and absolute reliability was evaluated by calculation of standard error of measurement (SEM) and minimal detectable change (MDC) using the raw ear scores. RESULTS: The Pearson correlation coefficient indicated that in both groups of children the ear scores of test and retest sessions were strongly and positively (greater than +0.8) correlated. The ear scores showed excellent ICC coefficient of consistency (0.78-0.82) and fair to excellent ICC coefficient of absolute agreement (0.62-0.74) in TA children and excellent ICC coefficients of consistency and absolute agreement in LD children (0.76-0.87). SEM and SEM% of the ear scores in TA children were 1.46 and 1.44% for the right ear and 4.68 and 5.47% for the left ear. SEM and SEM% of the ear scores in LD children were 4.55 and 5.88% for the right ear to 7.56 and 12.81% for the left ear. MDC and MDC% of the ear scores in TA children varied from 4.03 and 3.99% for the right ear to 12.93 and 15.13% for the left ear. MDC and MDC% of the ear scores in LD children varied from 12.57 and 16.25% for the right ear to 20.89 and 35.39% for the left ear. CONCLUSIONS: The LD children indicated test-retest relative reliability as high as TA children in the ear scores measured by PRDDT. However, within-subject variations of the ear scores calculated by indices of absolute reliability were considerably higher in LD children versus TA children. The results of the current study could have implications for detecting real training-related changes in the ear scores.

Effect of Play-based Therapy on Meta-cognitive and Behavioral Aspects of Executive Function: A Randomized, Controlled, Clinical Trial on the Students With Learning Disabilities.

INTRODUCTION: Although the effect of educational methods on executive function (EF) is well known, training this function by a playful method is debatable. The current study aimed at investigating if a play-based intervention is effective on metacognitive and behavioral skills of EF in students with specific learning disabilities. METHODS: In the current randomized, clinical trial, 49 subjects within the age range of 7 to 11 years with specific learning disabilities were randomly assigned into the intervention (25 subjects; mean age 8.5±1.33 years) and control (24 subjects; mean age 8.7±1.03 years) groups. Subjects in the intervention group received EF group training based on playing activities; subjects in the control group received no intervention. The behavior rating inventory of executive function (BRIEF) was administered to evaluate the behavioral and cognitive aspects of EF. The duration of the intervention was 6 hours per week for 9 weeks. Multivariate analysis of covariance was used to compare mean changes (before and after) in the BRIEF scores between the groups. RESULTS: The assumptions of multivariate analysis of covariance were examined. After controlling pre-test conditions, the intervention and control groups scored significantly differently on both the metacognition (P=0.002; effect size=0.20) and behavior regulation indices (P=0.01; effect size=0.12) of BRIEF. CONCLUSION: Play-based therapy is effective on the metacognitive and behavioral aspects of EF in students with specific learning disabilities. Professionals can use play-based therapy rather than educational approaches in clinical practice to enhance EF skills.
