Asthenic, inadequate, passive, and self-defeating personality (disorder)
It is a requirement of ICD-10 that a diagnosis of any specific personality disorder also satisfies a set of general personality disorder criteria. SWAP-200
The SWAP-200 is a diagnostic tool that was proposed with the goal of overcoming limitations, such as limited external validity for the diagnostic criteria for dependent personality disorder, to the DSM. It serves as a possible alternative nosological system that emerged from the efforts to create an empirically based approach to personality disorders – while also preserving the complexity of clinical reality. Dependent personality disorder is considered a clinical prototype in the context of the SWAP-200. Rather than discrete symptoms, it provides composite description characteristic criteria – such as personality tendencies.Based on the Q-Sort method and prototype matching, the SWAP-200 is a personality assessment procedure relying on an external observers judgment. It provides:

A personality diagnosis expressed as the matching with ten prototypical descriptions of DSM-IV personality disorders. A personality diagnosis based on the matching of the patient with 11 Q-factors of personality derived empirically. A dimensional profile of healthy and adaptive functioning.The traits that define dependent personality disorder according to SWAP-200 are:

They tend to become attached quickly and/or intensely, developing feelings and expectations that are not warranted by the history or context of the relationship. Since they tend to be ingratiating and submissive, people with DPD tend to be in relationships in which they are emotionally or physically abused. They tend to feel ashamed, inadequate, and depressed. They also feel powerless and tend to be suggestible.
Diagnosis
Clinicians and clinical researchers conceptualize dependent personality disorder in terms of four related components:

Cognitive: a perception of oneself as powerless and ineffectual, coupled with the belief that other people are comparatively powerful and potent. Motivational: a desire to obtain and maintain relationships with protectors and caregivers. Behavioral: a pattern of relationship-facilitating behavior designed to strengthen interpersonal ties and minimize the possibility of abandonment and rejection. Emotional: fear of abandonment, fear of rejection, and anxiety regarding evaluation by figures of authority. American Psychiatric Association and DSM
The Diagnostic and Statistical Manual of Mental Disorders (DSM) contains a dependent personality disorder diagnosis. It refers to a pervasive and excessive need to be taken care of which leads to submissive and clinging behavior and fears of separation. This begins prior to early adulthood and can be present in a variety of contexts.In the DSM Fifth Edition (DSM-5), there is one criterion by which there are eight features of dependent personality disorder. The disorder is indicated by at least five of the following factors:
Has difficulty making everyday decisions without an excessive amount of advice and reassurance from others. Needs others to assume responsibility for most major areas of their life. Has difficulty expressing disagreement with others because of fear of loss of support or approval. Has difficulty initiating projects or doing things on their own (because of a lack of self confidence in judgment or abilities rather than a lack of motivation or energy).
