The Psychometric Properties of Turkish Version of Autism Spectrum Screening Questionnaire in Children aged 6-18 years

The objective of this study is to determine the psychometric properties of the Turkish version of the Autism Spectrum Screening Questionnaire (ASSQ-TR) and to find the best cutoff score for Pervasive Developmental Disorder (PDD) cases. Children between 6 to 18 years old with diagnoses of PDD, Obsessive Compulsive Disorder (OCD), and Attention Deficit Hyperactivity Disorder (ADHD) were included. The healthy control (HC) group was recruited from children who did not have any psychiatric complaints or history. Furthermore, parents of 268 children filled the ASSQ-TR. Of the children, 51 were PDD, 67 were ADHD, 50 were OCD, and 100 were HC. In order to show the reliability of the ASSQ-TR, Cronbach's alpha values and test-retest were evaluated. ROC analyses was carried out to show concurrent validity and to determine the cutoff score. The Cronbach's alpha of ASSQ-TR is 0,86, while the test-retest reliability is r: 0,98. Total ASSQ-TR scores of children with PDD (27,96±9,5) were significantly higher than other groups (p<0,001). ROC analysis of ASSQ-TR showed the area under curve to be 0,97 with a cutoff of 16, having the maximum sensitivity (94,1%), specificity (89,0%), and 90,7% diagnostic accuracy of PDD versus HC scores. Our pilot data showed that ASSQ-TR is a reliable instrument that successfully differentiates clinically diagnosed PDD from HC. This instrument might therefore be useful for the screening of PDD in school-aged children in Turkish populations.

Psychometric Properties of Turkish Version of the Dutch Objective Burden Inventory

The purpose of this study was to assess the psychometric properties of the Dutch Objective Burden Inventory (DOBI) for the Turkish society. This is a descriptive, methodological study. The sample was composed of 230 heart failure patients' caregivers. The DOBI was translated using translation and back-translation. The translated Turkish version was submitted to eight experts who analyzed it for its content validity. Scores from the experts were evaluated using the Kendall W analysis, and no statistically significant difference was found among the scores (Kendall W=.13, p=.338). In the confirmatory factor analysis, factor loading was found to be between 0.75 and 1.00 for all subscales. Thus, the DOBI demonstrated acceptable internal consistency (the components displayed α scores from .96 to .99), good test-retest reliability (no statistically significant differences were found, p>.050). The Turkish version of the DOBI scale is a valid and reliable tool for the Turkish population. It can be used in nursing practices and research.

Psychometric Properties of Turkish Version of the Behavior Problems Scale for High School Students

Objective: The purpose of the study was to investigate the validity and reliability of the Behavior Problem Scale (BPS) in a sample of Turkish high school students. Methods: This is a descriptive study and confirmatory factor analysis was used. The scale was administered to 542 Anatolian high school students from 9th, 10th and 11th grades in Ankara. Results: Confirmatory factor analysis was conducted for both single and two-factor models of the BPS and the following indices were obtained: (χ2(35)=166.09, p=0.01; χ2/df-ratio=4.74; GFI=0.939, CFI=0.893, RMSEA=0.083, and SRMR=0.049) for two-factor model. The internal consistency of the BPS was assessed by Cronbach’s alpha, which was 0.80 for the total; 0.71 for rudeness; and 0.70 for disobedience. For criterion validity, Multidimensional Students’ Life Satisfaction Scale (MSLSS) was used. Pearson correlation coefficient revealed a significant negative correlation between BPS scores and MSLSS, suggesting that participants with a high BPS scores were more likely to score lower on the MSLSS. Conclusion: The results of this study showed that the Turkish version of the BPS provides a reliable and valid measure for Turkish high school students.

Psychometric Properties of the Turkish Version of the Composite Scale of Morningness

The Composite Scale of Morningness is widely used and translated into several languages. The aim of the study was to present psychometric properties of Turkish version of CSM based on a sample of high school and university students. A total of 543 high school and 650 university students have participated in to the study. The internal consistency coefficient was found to be .73 (high school) and .80 (university). The test-retest reliability of the scale was .89 in high school sample and .84 in university sample. The mean CMS scores did not differ by gender in both samples. Exploratory and confirmatory factor analysis revealed that the scale is valid. As an external validation, morningness was associated with MEQ scores, sleep length, mid-point of sleep, rising and retiring time. The data obtained in the study suggested that the Turkish version of the CSM is a reliable and valid instrument to assess circadian preference in both high school and university samples.

Psychometric Properties of Turkish Version of Childhood Trauma Questionnaire among Adolescents with Gender Differences

The aim of this study was to investigate the psychometric properties of the Turkish version of Childhood Trauma Questionnaire (CTQ) and its subscales among adolescents. The participants consisted of 1275 high school students (14 - 19 years) with a mean age of 16.33 (SD = 1.01). The confirmatory factor analysis has revealed that CTQ has three subscale (physical abuse, emotional abuse, sexual abuse). Cronbach’s alpha for the total scale was .91, for physical abuse .84, for emotional abuse .89, for sexaul abuse .70. The test-retest correlation coefficient for the total score (n = 65) was .81, for physical abuse .82, for emotional abuse .80, and sexual abuse .75 at 3 weeks indicating adequate reliability. Discriminant validity was satisfactory. The results of the study have shown that the Turkish version of CTQ psychometrically sound among high school students.

Psychometric properties of Turkish version of Dutch Eating Behaviour Questionnaire (DEBQ). A preliminary results

The purpose of this study was to test the reliability and validity of Dutch Eating Behaviour Questionnaire (DEBQ) among Turkish university students. The questionnaire was administered to 508 participants. Construct validity was assessed by principal component factor analysis with varimax rotation and reliability was tested by Cronbach's alpha coefficient. For testing criterion related validity, EAT-40 with DEBQ was also administered to 508 participants. Results showed the presence of three major factors (emotional eating, restrained eating and external eating) with loadings similar to those of the original questionnaire. Three subscales of DEBQ had higher internal consistency and test–retest reliability. The obtained correlation between EAT-40 and DEBQ was ranged from 0.12 to 0.39. This study clearly demonstrates the factorial validity and the reliability of a Turkish version of the DEBQ.

Validation study of the Turkish version of the Yale—Brown Obsessive Compulsive Scale for heavy drinking in a group of male patients

Psychometric properties of Turkish version of the Yale Brown Obsessive Compulsive Scale for heavy drinking (YBOCS-hd) were examined in alcohol-dependent male patients. Factor structure, internal consistency and discriminant validity of the YBOCS-hd were analysed in a sample of 117 male patients diagnosed with alcohol dependence. To study its convergent validity, the YBOCS-hd was correlated with the Addiction Severity Index in 34 of the patients. A test - retest reliability study was performed on the data from 34 patients. Correlation between the YBOCS-hd total score and the ASI Alcohol Use score was moderate (r = 0.51). One factor explained 50.2% of the variance. The YBOCS-hd was able to discriminate the groups abstinent for less than 1 month and a second group with at least 1 month of abstinence. Test - retest correlation was high (r = 0.81, ICC = 0.81). The Turkish version of the YBOCS-hd proved to be a reliable and valid instrument measuring craving in alcohol-dependent male individuals.
