“…It is important to note however that none of these studies employed the present methodology of a population-based random sample, as this method would be prohibitive because the cities cited earlier in this paper range in population from about 135,000 to over 13,000,000. The ADHD prevalence rate in the present study was also similar to studies conducted in the Middle East and Far East, for example, the ADHD prevalence rate was 8.1% in Turkey (Ersan, Dogan, Dogan, & Sumer, 2001), 9.4% in Qatar (Bener, Al Qahtani, & Abdelaal, 2006), and 8.9% in China (Leung et al 1996).…”

This study investigated the prevalence of attention-deficit/hyperactivity disorder (ADHD) in a rural population in Birjand, south east Iran. The total population of elementary students in this region was 3408. A random sample method selected 1381 children (727 boys, and 654 girls; mean of age = 8.2 years, SD = 1.5 years). Conners Rating Scales and Diagnostic and the Statistical Manual for Mental Disorders (DSM-IV-TR) were used for screening and diagnosis of ADHD. Ninety-nine students (7.2% of the students) were identified as ADHD (10.3% of the boys and 3.7% of the girls). The combined ADHD subtype was the most prevalent (44%), hyperactive-impulsive subtype was second (38%), and inattentive was third (17%). This subtype pattern was the same for boys, however, hyperactive-impulsive subtype more prevalent in girls (63%). It seems that ADHD appears to be a common problem among primary school children in the rural Iran, and findings are similar but higher than world-wide ADHD prevalence estimates (5.3%). The present prevalence rate for ADHD is closer to world-wide study estimates that are based on DSM-IV and International Classification of Diseases (ICD-10) criteria.

“…However, the prevalence we found was higher than that of other prevalence studies carried out in Turkey in different years. A study conducted by Gul et al, 32 for instance, reported a prevalence of 8.6% and another one, reported by Ersan et al, 33 found a prevalence of 8.1%. Güler et al, 34 by contrast, reported a prevalence of 2.7-9.6% based on parent assessment and 2-10.1% based on teacher evaluation.…”

“…The global subtype studies reported that the combined and the inattentive types were the most common, 24,25 while two epidemiological studies from Turkey found that the hyperactive type was the most common. 32,33 These differences in the rates of various subtypes may stem from methodological variations as well as cultural discrepancies. More society-based studies are needed to interpret our results with respect to subtype distribution.…”

Objective: We evaluated the prevalence of attention-deficit/hyperactivity disorder (ADHD) among primary school children in Nicosia, a province of the Turkish Republic of Northern Cyprus (TRNC). interview (Kiddie Schedule for Affective Disorders and Schizophrenia for School Aged Children-Present and Lifetime; K-SADS-PL). ADHD was diagnosed with use of the K-SADS-PL in both children and their parents as well as in accordance with DSM-IV-TR ÖZET Amaç: Kuzey Kıbrıs Türk Cumhuriyeti'ndeki (KKTC) ilkokul öğrencilerinde dikkat eksikliği/hiperaktivite bozukluğu-nun (DEHB) yaygınlığını araştırdık. Yöntem: DEHB değerlendirme ölçekleri 6-11 yaş arasındaki ilkokul öğrencile-rinin anne-babaları ve öğretmenleri tarafından dolduruldu. Çalışma iki basamakta gerçekleştirildi. Birinci basamakta Turgay DSM-IV-Yıkıcı Davranış Bozuklukları Çocuk ve Adolesan Değerlendirme ve Tarama Ölçeği (T-DSM-IV-S) ölçeği 1140 öğrencinin ailesine yollandı. Aynı ölçek, ölçeği doldurulmuş olan çocukların öğretmenlerine de verildi. İkinci basamakta anne-babaları veya öğretmenleri tarafından doldurulan ölçeklerde 12 puandan fazla alan çocuk-ların anne-babaları ve çocukları yarı yapılandırılmış görüşme (Çocuk ve Gençler için Duygulanım Bozuklukları ve Şizofreni ölçeği; K-SADS-PL) için kliniğe çağırıldı. DEHB tanısı çocuklarda ve anne-babalarında hem K-SADS-PL kullanılarak, hem de DSM-IV-TR

“…Pierrehumbert et al [8] reported no difference in the prevalence of ADHD symptoms in school-aged Swiss children between parent (8.0%) and teacher (9.6%) evaluations, using the clinical cutoff point for the ADHD index. Erşan et al [10] found no significant difference in ADHD symptoms of school-aged Turkish children, using DSM-IV criteria, based on parent (9.6%) and teacher (7.3%) evaluations. Furthermore, Polanczyk and Jensen [7] retrieved 71 studies during a recent systematic review of epidemiological studies on ADHD published in the last decade.…”

Objective Clarifying the characteristics of attention-deficit/ hyperactivity disorder (ADHD) symptoms in childhood is important for the prevention and management of this disorder. The purpose of this study was to determine the prevalence of ADHD symptoms in Japanese preschool children based on evaluations performed by parents or teachers. Methods A questionnaire survey was performed to evaluate the estimated prevalence of ADHD symptoms in preschool children in Niigata City, Japan. The first survey, conducted in 2003, involved an evaluation of ADHD symptoms by their school teachers. The second survey, conducted in 2006, involved an evaluation of the symptoms by parents. The teacher survey included 9,956 children, and the parent survey included 7,566 children. Parents and teachers assessed ADHD symptoms in children using a 14-item questionnaire based on DSM-III-R. Children with a score of 8 or higher were classified as having ADHD symptoms. Results The overall prevalence of ADHD symptoms was 2,349/7,566 (31.1%) in the parent survey and 431/9,956 (4.3%) in the teacher survey, with a prevalence ratio of 7.2 (95% CI: 6.5-7.9). Likelihood ratio test indicated that variables significantly associated with the presence of ADHD symptoms were gender, age, school type, interaction between gender and observer, and interaction between school type and observer (each with P \ 0.0001). ConclusionsThe large difference between the estimated prevalence of ADHD symptoms in Japanese preschool children from teacher and parent surveys suggests that compared to teachers, parents consider their children's symptoms much more serious. Thus, parental evaluation of ADHD symptoms using DSM criteria may be inappropriate for ADHD screening.
