There is a need for brief screening tools to identify adolescents at risk for anxiety disorders. The Youth Anxiety Measure for DSM-5 has been recently developed to assess youths’ anxiety symptoms in terms of the current classification system. The goal of this study is to provide a first test of its psychometric properties in a community sample of adolescents in Spain. Methods: The sample consisted of 505 13- to 17-year-old adolescents who completed Part I of the YAM-5 (YAM-5-I), which measures symptoms of the major anxiety disorders. Results: Data indicated that the YAM-5-I displays appropriate internal consistency reliability. In addition, support was also found for the construct validity of the measure: most items loaded on a factor that represented the hypothesized anxiety syndromes, although it should also be noted that some items exhibited issues and therefore had to be discarded. Limitations: Cross-cultural and trans-national studies are needed to determine psychometric properties of scale across languages and cultures. Conclusions: Our findings suggest that the YAM-5-I has satisfactory psychometric properties, which indicates that it can be used as a screening tool in Spanish-speaking adolescents from the general population. 1. Introduction Anxiety disorders are among the most prevalent mental health problems. Although current anxiety scales have proven to be reliable and valid indices of anxiety symptomatology in youths, they are not up to date with the latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013). However, DSM-5 has made two main changes with regard to the anxiety disorders section: (1) selective mutism is now included as anxiety appears to be a key symptom of this problem (Muris and Ollendick, 2015), while (2) obsessive-compulsive disorder and trau- matic stress disorders have been removed from the section as they are no longer considered as pure anxiety syndromes. In an attempt to construct a screening scale for assessing anxiety symptoms in children and adolescents in terms of the contemporary classification system, Muris et al. (2016) recently developed the Youth Anxiety Measure for DSM-5 (YAM-5), with good psychometric proper- ties. The YAM-5 consists of two parts: Part I is measuring symptoms of the major anxiety disorders (i.e., separation anxiety disorder, general- ized anxiety disorder, panic disorder, social anxiety disorder, and selective mutism), whereas Part II is dedicated to assess symptoms of phobias (i.e., various types of specific phobias and agoraphobia). The present study aimed to investigate the reliability and validity of Part I of the newly developed YAM-5 in Spanish adolescents. More specifically, we examined (a) age and gender differences; (b) factor structure of the recently designed scale; (c) measurement invariance in gender and age; (d) reliability of scale; and (e) concurrent validity of scale with social anxiety measures. 2. Method 2.1. Participants The sample consisted of 505 participants aged between 13 and 17 years old (M =14.94, SD =1.25), of which 238 (47%) were boys. Participants were recruited from 1 private and 4 public high schools in a medium-size state in the south of Spain. Schools were selected by a clustered random sampling method from the school lists of the Department of Education to ensure that the socioeconomic status and ethnic composition of the sample were representative of the http://dx.doi.org/10.1016/j.jad.2016.10.045 Received 26 June 2016; Accepted 22 October 2016 ⁎ Corresponding author.
