ABSTRACT
OBJECTIVES: Mental chronometry is the scientific study of cognitive processing speed measured by reaction time (RT), which is the elapsed time between the onset of a stimulus and an individual's response. This study aims at measuring the RT among young children with autism spectrum disorders (ASD) and comparing it with normal (typically developing) children. METHODS: 60 ASD children were selected from different ASD centers, and 60 normal children were selected from different kindergartens for participation in this study. Participants were aged 3-6 years old. The RT was measured using the Fitlight trainer device. The findings were statistically evaluated using independent t-tests and ANOVA tests. RESULT: Significant differences (p < 0.0001) were found between both groups in all tasks, and ASD children demonstrated slower RT compared to the normal group. The RT measured through three senses (visual, auditory, and touch) for ASD and normal were 3.64 ± 2.16, 13.19 ± 2.41(trial), 1835.23 ± 757.95, 697.12 ± 87.83 (second), and 1550.89 ± 499.76, 752.67 ± 124.02 (second) respectively. CONCLUSION: The evaluated RT showed significant impairment in RT among ASD in comparison to normal children and this was true for the three senses. The Fitlight trainer could be used to assess RT and stimulus-response among ASD children in various cognitive tasks. Similar studies, involving larger samples from different areas and involving other sense organs, are indicated to confirm the results.
ABSTRACT
BACKGROUND AND OBJECTIVE: This study aims at assessing the prevalence and risk factors of Adjustment disorder (AD), the AD subtypes, and the common causing stressors. PATIENTS AND METHODS: A cross sectional study was conducted at outpatient psychiatric clinic in Duhok City from July 2008 to July 2009. 637 patients equal and above 18 of both genders were selected randomly. SCID-I/P (Version 2.0) was adopted to diagnose patients with AD. SPSS (version 21), was used for data analysis. RESULTS: The study showed that the prevalence of AD was 11.5%. It was more common among youngest age group (15-25 years) with a rate 69.9% (p=0.001) while lowest educational level (illiterate and primary) 53.5% (p=0.040), single 54.8% (p<0.001), students 39.7 (p<0.001) and from urban areas 71.2% (p=0.012) with statistically significant association. Although AD was more common among females (61.6%), no significant association was found between AD and gender (p=0.380). The most common subtype of AD was AD with mixed anxiety and depressed mood (34.2%) and was the commonest among females (19.2%) followed by AD with Anxiety subtype 30.1% which was the commonest among males (13.7%). The commonest psychosocial stressor was the illnesses (28.8%) followed by love affairs (26%) and domestic problems (16.4%). CONCLUSIONS: The prevalence of AD was found to be high. The risk factors included young, low educational level, single, students, and those from urban areas. The most common subtype was AD with mixed anxiety and depressed mood and the commonest psychosocial stressor was the illnesses followed by love affairs and domestic problems.
