Researchers also claimed that the PHQ-9 provides the clinically appropriate classification of symptoms to be used for planning care (Mitchell, Yadegarfar, Gill, & Stubbs, 2016 Pratt & Brody, 2014 Simon et al., 2016). (2017) noted that predictive validity of this instrument is high, and the PHQ-9 has relevant psychometric properties to be applied to wide populations. According to Burdzovic and Brunborg (2017), this tool can be used for adolescents who belong to different cultures and backgrounds without decreasing its validity or minimizing effectiveness. The PHQ-9 is a valid and reliable instrument for detecting signs of depression, as it is reported in many studies with reference to different ethnic and cultural contexts. Apply the Findings of the Scholarly Research Articles to the Use of This Evaluation Tool and Describe Its Validity and Reliability This tool is effective to measure depression in adolescents with the focus on identifying possible suicidal ideations. Thus, the PHQ-9 is important to identify patients with a high risk of suicide attempts depending on the severity of reported symptoms (Simon et al., 2016). Furthermore, the PHQ-9 is essential for diagnosing adolescents and providing appropriate care because this instrument also measures the severity of depression. The instrument is easy to use, and adolescents usually have no problems with filling the PHQ-9 protocol.
PHQ 9 ADOLESCENT VALIDITY AND RELIABILITY MANUAL
The version for adolescents includes nine items that are helpful to indicate signs of depression according to the Diagnostic and Statistical Manual of Mental Disorders, and this aspect adds to the PHQ-9’s validity (Breland et al., 2014). The PHQ-9 is a self-report assessment instrument that is applied to screen early signs of depression in adolescents.
