An Analysis of High School Students' Academic Achievement and Anxiety Over Graphical Chemistry Problems About The Rate of Reaction: The Case of Sivas Province

The study deals with the evaluation of the achievement of high school students concerning such topics as "reaction rate, reaction order, factors affecting reaction" which are included in the unit of "Reaction Rate and Chemical Equilibrium", a part of chemistry program. To this, three measurement tools used as data collection tools; the "Achievement Test on Reaction Rate" (RRAT), the "Graphical Test on Reaction Rate (RRGT) and the "Anxiety Scale on the Use of Graphics" (ASUG) in chemistry problems. The participants of the study were 129 eleventh graders attending four Anatolian high schools in the province of Sivas. The study was carried out on one group. The findings obtained showed that the participants had higher mean scores in RRAT in contrast to those in RRGT. It was further found that the anxiety of the participants in regarding to the problems with graphics is higher. It was also determined that there is a statistically significant, negative and weal correlation between the student achievement in RRGT and the anxiety levels in regarding to the problems with graphics.

The effect of sleep disorders on quality of life in patients with epilepsy: A multicenter study from Turkey

Objective: We aimed to investigate sleep disorders in patients with epilepsy (PWE) and to investigate the effects of sleep disorders on quality of life. Methods: In our multicenter study conducted in Turkey, 1358 PWE were evaluated. The demographic and clinical data of the patients were recorded. The Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), and Quality of Life in Epilepsy Inventory-10 (QOLIE-10) were administered. Results: The mean age of 1358 patients was 35.92 ± 14.11 (range, 18–89) years. Seven hundred fifty-one (55.30 %) were women. Some 12.7 % of the patients had insomnia (ISI > 14), 9.6 % had excessive daytime sleepiness (ESS > 10), 46.5 % had poor sleep quality (PSQI > 5), and 354 patients (26.1 %) had depressive symptoms (BDI > 16). The mean QOLIE-10 score was 22.82 ± 8.14 (10–48). Resistant epilepsy was evaluated as the parameter with the highest risk affecting quality of life Adjusted odds ratio (AOR = 3.714; 95 % confidence interval (CI): [2.440–5.652] < 0.001)). ISI (AOR = 1.184; 95 % CI: [1.128–1.243]; p < 0.001), ESS (AOR = 1.081; 95 % CI: [1.034–1.130]; p < 0.001), PSQI (AOR = 0.928; 95 % CI: [0.867 – 0.994]; p = 0.034), BDI (AOR = 1.106; 95 % CI: [1.084–1.129]; p < 0.001), epilepsy duration (AOR = 1.023; 95 % CI: [1.004–1.041]; p = 0.014), were determined as factors affecting quality of life. Significance: Sleep disorders are common in PWE and impair their quality of life. Quality of life can be improved by controlling the factors that may cause sleep disorders such as good seizure control, avoiding polypharmacy, and correcting the underlying mood disorders in patients with epilepsy
