The Effectiveness of Sensory-Motor Integration Exercises on Social Skills and Motor Performance in Children with Autism

PURPOSE

The current study aims to investigate the effectiveness of sensory-motor integration exercises on social skills and motor performance in children with autism spectrum disorder (ASD).

METHODS

This is a quasi-experimental study with a pre-test-post-test design and with a control group. The statistical population of this research included all children with ASD aged 9-11 years old in Babolsar city in 2022, among whom 30 were selected through convenient sampling from the transplant center of Babolsar, and were randomly assigned into two experimental and control groups. Then, the experimental group received the treatment program in 12 sessions. The data collection instrument included Gresham and Elliott's social skills questionnaire (Gresham FM, Elliott SN (1993) Social skills intervention guide: systematic approaches to social skills training. Spec Serv Sch 8(1):137-158) and Ulrich's motor performance test (Ulrich B, Ulrich D (1985) The role of balancing ability in performance of fundamental motor skills in 3-, 4-, and 5-year-old children. Motor Dev: Curr Select Res 1:87-97). Data analysis was conducted using covariance analysis in SPSS21.

RESULTS

The multivariate covariance analysis test showed that there is a significant difference between the experimental and control groups in the variable of social skills and motor performance, respectively (P < 0.001).

CONCLUSION

According to the research findings, it can be concluded that sensory-motor integration exercises can be used as an appropriate intervention in promoting and improving social skills and motor performance of children with autism spectrum. Results of this study can be helpful for therapists and educators who deal with autistic children.

Screen Time and Autism Spectrum Disorder: A Systematic Review and Meta-Analysis

Importance

Contemporary studies raise concerns regarding the implications of excessive screen time on the development of autism spectrum disorder (ASD). However, the existing literature consists of mixed and unquantified findings.

Objective

To conduct a systematic review and meta-analyis of the association between screen time and ASD.

Data Sources

A search was conducted in the PubMed, PsycNET, and ProQuest Dissertation & Theses Global databases for studies published up to May 1, 2023.

Study Selection

The search was conducted independently by 2 authors. Included studies comprised empirical, peer-reviewed articles or dissertations published in English with statistics from which relevant effect sizes could be calculated. Discrepancies were resolved by consensus.

Data Extraction and Synthesis

This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline. Two authors independently coded all titles and abstracts, reviewed full-text articles against the inclusion and exclusion criteria, and resolved all discrepancies by consensus. Effect sizes were transformed into log odds ratios (ORs) and analyzed using a random-effects meta-analysis and mixed-effects meta-regression. Study quality was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. Publication bias was tested via the Egger z test for funnel plot asymmetry. Data analysis was performed in June 2023.

Main Outcomes and Measures

The 2 main variables of interest in this study were screen time and ASD. Screen time was defined as hours of screen use per day or per week, and ASD was defined as an ASD clinical diagnosis (yes or no) or ASD symptoms. The meta-regression considered screen type (ie, general use of screens, television, video games, computers, smartphones, and social media), age group (children vs adults or heterogenous age groups), and type of ASD measure (clinical diagnosis vs ASD symptoms).

Results

Of the 4682 records identified, 46 studies with a total of 562 131 participants met the inclusion criteria. The studies were observational (5 were longitudinal and 41 were cross-sectional) and included 66 relevant effect sizes. The meta-analysis resulted in a positive summary effect size (log OR, 0.54 [95% CI, 0.34 to 0.74]). A trim-and-fill correction for a significant publication bias (Egger z = 2.15; P = .03) resulted in a substantially decreased and nonsignificant effect size (log OR, 0.22 [95% CI, -0.004 to 0.44]). The meta-regression results suggested that the positive summary effect size was only significant in studies targeting general screen use (β [SE] = 0.73 [0.34]; t58 = 2.10; P = .03). This effect size was most dominant in studies of children (log OR, 0.98 [95% CI, 0.66 to 1.29]). Interestingly, a negative summary effect size was observed in studies investigating associations between social media and ASD (log OR, -1.24 [95% CI, -1.51 to -0.96]).

Conclusions and Relevance

The findings of this systematic review and meta-analysis suggest that the proclaimed association between screen use and ASD is not sufficiently supported in the existing literature. Although excessive screen use may pose developmental risks, the mixed findings, the small effect sizes (especially when considering the observed publication bias), and the correlational nature of the available research require further scientific investigation. These findings also do not rule out the complementary hypothesis that children with ASD may prioritize screen activities to avoid social challenges.

Effect of Mobile Phone Addiction on Physical Exercise in University Students: Moderating Effect of Peer Relationships

OBJECTIVE

The influence of mobile phone addiction (MPA) on physical exercise in university students was explored, and peer relationships were introduced as a moderating variable.

METHODS

A cross-sectional study design was adopted, and an online survey questionnaire was conducted to investigate two universities in Nantong City, Jiangsu Province, and Chongzuo City, Guangxi Zhuang Autonomous Region. A total of 4959 university students completed the questionnaire. Measurement tools included the Mobile Phone Addiction Tendency Scale, the Physical Activity Rating Scale, and the Peer Rating Scale of university students.

RESULTS

University students scored 39.322 ± 15.139 for MPA and 44.022 ± 7.735 for peer relationships, with 87.8% of their physical exercise, in terms of exercise grade, being classified as medium or low intensity. The MPA of the university students was negatively correlated with peer relationships (r = -0.377, p < 0.001) and physical exercise behavior (r = -0.279, p < 0.001). The moderating effect of peer relationships on the MPA-physical exercise behavior relationship was significant (ΔR² = 0.03, p < 0.001).

CONCLUSIONS

The physical exercise of university students was at a medium or low intensity. The more serious the university students' addiction to mobile phones was, the lower the amount of physical exercise. The physical activity of males was higher than that of females. MPA and peer relationships were the limiting factors of the physical exercise behavior of university students. Under the lower effect of peer relationship regulation, MPA had a greater negative impact on physical exercise behavior. The data from this research can provide theoretical support to improve the participation of university students in physical activities.
