Depression is a precise and unswerving disorder which is categorized by fixed established symptoms and is generally cured with a combination of psychotherapy and medication. in order to diagnose healthcare professionals and researchers used standard rating scale to diagnose this disease differ as per the symptoms they grade.  It has been observed that one-size-fits-all treatment is ineffective according to the finding of Eiko Fried from the University of Amsterdam (UvA).  Depression is often viewed as a common medical disorder. To determine in is having depression or not the researchers and clinicians question patients about the symptoms that are symptomatic of depression, like sadness, feeling of suicidal willingness or sleep problems. In case those person who have many depression signs, it is considered that he /she is depressed. To see the heterogeneous nature of depression Fried investigation is very useful to get a conclusion.


Fried utilized a substance examination to explore the manifestation cover of 7 rating sizes of side effects that are regularly utilized as a part of Fried research. One of the scales is the Hamilton Rating Scale of Depression, which contains 17 prevalently physical misery indications like loss of motion, weight reduction and psychomotor impediment. Another is the Beck Depression Inventory, which incorporates 21 for the most part psychological full of feeling side effects, for example, emotions like uselessness, blame, crying and self-hate.
What he found was that these and other rating scales demonstrate shockingly little manifestation cover. Also, together they highlight an aggregate of 52 distinctive despondency indications running from misery, absence of intrigue and self-destructive ideation to genital issues, crabbiness and uneasiness. These discoveries underline the striking heterogeneity of melancholy, a confusion for the most part saw as one predictable disorder, says Fried. 'Patients determined to have despondency are regularly thought to have comparative sorts of issues and in this way get fundamentally the same as treatment. In any case, the way that 7 regular rating sizes of melancholy contain more than 50 unique manifestations demonstrates how strikingly extraordinary discouraged patients can be as far as the issues they encounter. This appears to demonstrate the requirement for more customized treatment and might clarify why ebb and flow "one-estimate fits-all" arrangements like antidepressants show so little viability.'

Foreordained result

Fried trusts his discoveries could likewise represent a noteworthy issue for dejection inquire about on the grounds that the kind of scale utilized by specialists may decide the result of a logical study. Broiled: 'For instance, envision you are a scientist and need to concentrate on the mind structure of discouraged patients. This is normally done by giving an expansive gathering of individual’s one particular dejection scale, and if these individuals have a specific number of side effects they are enlisted into the study as discouraged.' According to Fried, his discoveries propose that the sort of scale a scientist uses may manage the sort of individuals who are selected in the study. 'For example, if a specialist uses Hamilton's scale, which is centered around physical indications, the sorts of members she looks at in her cerebrum study will vary drastically from the individuals who might be selected if she somehow happened to utilize Beck's intellectual full of feeling scale. Furthermore, these distinctive gatherings of individuals will probably vary in their cerebrum structures. As this and earlier studies appear, discouraged individuals contrast significantly in the issues they experience and side effects they show. This reasonable clarifies why such a large number of various sorrow thinks about arrive at altogether different conclusions.'
