Some practical aspects should be considered by the clinician when evaluating major depressive disorder (Dozois & Dobson, 2009). Depressed individuals tend to express their problems in detail when they are aware of what is expected of them during the initial assessment phase. Warning depressed clients about possible disruptions early on, in addition to providing motivation, helps improve the effectiveness of the assessment (Dozois & Dobson, 2009). Since depressed individuals tend to commit cognitive biases (Dozois & Beck, 2008), it is necessary to determine the actual deterioration by evaluating the patient's daily routine in terms of different areas of functioning. Each diagnostic criterion must be addressed in different ways (Shea, 1988). Sometimes, the patient describes their symptoms in a more peculiar way. Therefore, the doctor must translate these concerns into the nosological system (Dozois & Dobson, 2009). Bolland and Keller (2009) underline the need to evaluate the number of previous episodes and their duration since this information is one of the predictive factors of the risk of subsequent relapse (Solomon et al, 2000). Dozois and Dobson (2009) reported relying carefully on information from the previous episode as the client may make reporting errors. Reporting bias can be reduced by ensuring that the patient understands the time frame to which he or she is referring (Dozois & Dobson, 2009) and by providing contextual cues to the patient's memory (Shea, 1988). Information regarding previous treatments, medical history, the patient's motivation for change, etc. they can help identify resources for change (Dozois & Dobson, 2009). It is also helpful to assess the client's strengths, which will help formulate... half of the document... however, if medical conditions worsen the symptoms of depression, the mood disorder is diagnosed as major depressive disorder and the medical condition is diagnosed as major depressive disorder. listed in Axis III of the DSM-IV-TR (APA, 2000a). It is difficult to distinguish between depression and dementia (Gualtieri and Johnson, 2008), but some differences can be noted between the two (Dozois and Dobson, 2009). For example, in depression recent memory is more affected than remote memory; such symptoms are not prominent in dementia (Dozois and Dobson, 2009). Conclusion: For an accurate assessment of major depressive disorder, the clinician should not rely on results obtained from a psychometric instrument. Rather, it should seek to integrate information obtained from multiple sources to obtain a holistic picture of the patient. Clinicians must also consider the above-mentioned practical issues while carrying out the assessment for major depressive disorder.
