Template:Personality disorders sidebarDependent personality disorder (DPD) is a personality disorder characterized by a pervasive dependence on other people and subsequent submissiveness<ref name=":2">Template:Cite book</ref><ref name=":1" /> and clinginess.<ref name=":1" /> This personality disorder is a long-term condition<ref>Template:Cite web</ref> in which people depend on others to meet their emotional and physical needs. Individuals with DPD often struggle to make independent decisions and seek constant reassurance from others.<ref name=":1">Template:Cite book</ref> This dependence can result in a tendency to prioritize the needs and opinions of others over their own.<ref name="Practitioner's Guide to Evidence-Ba" />

People with DPD depend excessively on others for advice, decision-making and the fulfillment of other needs, as they lack confidence in their abilities, competence and judgment.<ref name="Practitioner's Guide to Evidence-Ba">Template:Cite book</ref> They may thus act passively and avoid responsibilities, delegating them to others.<ref name=":1" /> Additionally, individuals with this disorder often display a pessimistic outlook, anticipating negative outcomes in various situations. They may also be introverted, highly sensitive to criticism, and fearful of rejection.<ref name="Practitioner's Guide to Evidence-Ba" />

They typically prefer not to be alone and may experience distress, isolation, or loneliness when separated from their support system, such as a close relationship with someone they depend on. They may thus feel a need to try to obtain a new such relationship quickly.<ref name=":1" /> In order to ensure that they retain people they depend on, those with DPD are willing to meet their wishes and demands,<ref name=":2" /> even when it entails self-sacrifice such as letting others abuse them.<ref name=":1" /> People with DPD may also fear that expressions of disagreement or anger may result in others leaving them.<ref name=":1" />

In the current edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR; 2022), dependent personality disorder is classified as a cluster C ("anxious or fearful") personality disorder.<ref>Template:Cite book</ref> There was a diagnostic category for DPD in the previous revision of the International classification of Diseases, ICD-10; but the ICD-11 no longer has distinct diagnoses for personality disorders.

Template:Visible anchor of DPD is typically in the form of psychotherapy,<ref name="Dependent Personality Disorder">Template:Cite web</ref> The main goal of this therapy is to make the individual more independent and help them form healthy relationships with the people around them. This is done by improving their self-esteem and confidence.<ref name="Dependent Personality Disorder" /> Particularly, cognitive-behavioral therapy (CBT) aims to improve self-confidence, autonomy, and coping mechanisms.<ref name=":2" /> Medication can be used to treat patients who suffer from depression or anxiety because of their DPD, but this does not treat the core problems caused by the disorder.<ref name="Dependent Personality Disorder" />

Causes

The exact cause of dependent personality disorder is unknown,<ref name="Sed2009">Template:Cite book</ref> but has been associated with various genetic and environmental factors. A study in 2012 estimated that between 55% and 72% of the risk of the condition is inherited from one's parents.Template:Sfn

Dependent traits in children tended to increase with parenting behaviours and attitudes characterized by overprotectiveness and authoritarianism. Thus the likelihood of developing dependent personality disorder increased, since these parenting traits can limit them from developing a sense of autonomy, rather teaching them that others are powerful and competent.<ref name=":02">Template:Cite book</ref> Individuals with a history of neglect or an abusive upbringing may have an increased risk of developing DPD,Template:Citation needed particularly those who have experienced long-term abusive relationships.Template:Citation needed

The difference between a "dependent personality" and a "dependent personality disorder" is somewhat subjective, which makes diagnosis sensitive to cultural influences such as gender role expectations.<ref>Template:Cite journal</ref> There is a higher frequency of the disorder seen in women than men; hence, expectations relating to gender role may contribute to some extent.<ref name=":02" />

Research suggests a link between DPD and a family history of anxiety disorders. A 2004 twin study reported a heritability estimate of 0.81 for personality disorders collectively, indicating a strong genetic component in their development.<ref name="Coolidge,">Template:Cite book</ref> Traumatic or adverse experiences early in an individual's life, such as neglect and abuse or serious illness, can increase the likelihood of developing personality disorders, including dependent personality disorder, later in life. This is especially prevalent for those individuals who also experience high interpersonal stress and poor social support.<ref name=":02" />

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.<ref name="Practitioner's Guide to Evidence-Ba" />

DSM

Template:Further The American Psychiatric Association's 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.<ref>Template:Cite web</ref>

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:<ref name=":06">Template:Cite book</ref>

  1. Has difficulty making everyday decisions without an excessive amount of advice and reassurance from others.
  2. Needs others to assume responsibility for most major areas of their life.
  3. Has difficulty expressing disagreement with others because of fear of loss of support or approval.
  4. 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).
  5. Goes to excessive lengths to obtain nurturance and support from others, to the point of volunteering to do things that are unpleasant.
  6. Feels uncomfortable or helpless when alone because of exaggerated fears of being unable to care for themselves.
  7. Urgently seeks another relationship as a source of care and support when a close relationship ends.
  8. Is unrealistically preoccupied with fears of being left to take care of themselves.<ref>American Psychiatric Association. (2013). Diagnostic and statistical manual of mental disorders (5th ed.). Washington, DC: Author.</ref>

Alternative model

The diagnosis of personality disorders in the fourth edition of the DSM, including dependent personality disorder, was found to be problematic due to reasons such as excessive diagnostic comorbidity, inadequate coverage, arbitrary boundaries with normal psychological functioning, and heterogeneity among individuals within the same categorial diagnosis.<ref>Template:Cite journal</ref> As a result of deficits of this system for personality disorders, the DSM-5 introduced a new model called the Alternative DSM-5 Model for Personality Disorders (AMPD).<ref>Template:Cite book</ref> The AMPD does not list dependent personality disorder as its own diagnostic entity.<ref name=":12">Template:Cite journal</ref> However, it is stated in the AMPD that what is conceptualized as DPD can instead be diagnosed as personality disorder – trait specified,<ref name=":12" /><ref>Template:Cite book</ref> which is a dimensional diagnosis that is constructed from the individual expression of personalty disorder,<ref>Template:Cite journal</ref> as manifested in both a general impairment in personality functioning along with at least one pathological personality trait.<ref>Template:Cite journal</ref>

ICD

Template:Further The World Health Organization's ICD-11 has replaced the categorical classification of personality disorders in the ICD-10 with a dimensional model containing a unified personality disorder (Template:ICD11) with severity specifiers, along with specifiers for prominent personality traits or patterns (Template:ICD11).<ref>Template:Cite journal</ref> Severity is assessed based on the pervasiveness of impairment in several areas of functioning, as well as on the level of distress and harm caused by the disorder,<ref>Template:Cite journal</ref> while trait and pattern specifiers are used for recording the manner in which the disturbance is manifested.<ref>Template:Cite journal</ref> Dependent personality disorder shows a consistent association with the ICD-11 trait domain Negative Affectivity (Template:ICD11), reflecting features such as low self-confidence and reliance on others.<ref name=":0">Template:Cite journal</ref> It is also frequently linked to Disinhibition (Template:ICD11), possibly due to ICD-11's inclusion of irresponsibility within that domain.<ref name=":0" /> Prior trait-based research and expert sources suggest that impulsivity may also be related to dependent traits.<ref name=":0" />

The previous edition, namely the ICD-10, lists dependent personality disorder as Template:ICD10 Dependent personality disorder:<ref name="dependent">Dependent personality disorder - International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10) Template:Webarchive</ref>

It is characterized by at least 4 of the following:

  1. Encouraging or allowing others to make most of one's important life decisions;
  2. Subordination of one's own needs to those of others on whom one is dependent, and undue compliance with their wishes;
  3. Unwillingness to make even reasonable demands on the people one depends on;
  4. Feeling uncomfortable or helpless when alone, because of exaggerated fears of inability to care for oneself;
  5. Preoccupation with fears of being abandoned by a person with whom one has a close relationship, and of being left to care for oneself;
  6. Limited capacity to make everyday decisions without an excessive amount of advice and reassurance from others.

Associated features may include perceiving oneself as helpless, incompetent, and lacking stamina.

Includes:

  • 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.<ref name=":06"/> 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.<ref name=":06"/>

Based on the Q-Sort method and prototype matching, the SWAP-200 is a personality assessment procedure relying on an external observer's 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.<ref name=":06"/>

The traits that define dependent personality disorder according to SWAP-200 are:

  1. 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.
  2. Since they tend to be ingratiating and submissive, people with DPD tend to be in relationships in which they are emotionally or physically abused.
  3. They tend to feel ashamed, inadequate, and depressed.
  4. They also feel powerless and tend to be suggestible.
  5. They are often anxious and tend to feel guilty.
  6. These people have difficulty acknowledging and expressing anger and struggle to get their own needs and goals met.
  7. Unable to soothe or comfort themselves when distressed, they require involvement of another person to help regulate their emotions.<ref name=":06"/>

Psychodynamic Diagnostic Manual

The Psychodynamic Diagnostic Manual (PDM) approaches dependent personality disorder in a descriptive, rather than prescriptive sense and has received empirical support. The Psychodynamic Diagnostic Manual includes two different types of dependent personality disorder:<ref name=":06"/>

  1. Passive-aggressive
  2. Counter-dependent <ref name=":06"/>

The PDM-2 adopts and applies a prototypic approach, using empirical measures like the SWAP-200. It was influenced by a developmental and empirically grounded perspective, as proposed by Sidney Blatt.<ref name=":06"/> This model is of particular interest when focusing on dependent personality disorder, claiming that psychopathology comes from distortions of two main coordinates of psychological development:

  1. The anaclitic/introjective dimension.
  2. The relatedness/self-definition dimension.<ref name=":06"/>

The anaclitic personality organization in individuals exhibits difficulties in interpersonal relatedness, exhibiting the following behaviours:

  • Preoccupation with relationships
  • Fear of abandonment and of rejection
  • Seeking closeness and intimacy
  • Difficulty managing interpersonal boundaries
  • Tend to have an anxious-preoccupied attachment style.<ref name=":06"/>

Introjective personality style is associated with problems in self-definition.<ref name=":06"/>

Differential diagnosis

Similarities between individuals with dependent personality disorder and individuals with borderline personality disorder include having a fear of abandonment. Those with dependent personality disorder do not necessarily exhibit impulsive behaviour or unstable affect experienced by those with borderline personality disorder, differentiating the two disorders.<ref>Template:Cite book</ref>

Epidemiology

Based on a recent survey of 43,093 Americans, 0.49% of adults meet diagnostic criteria for DPD (National Epidemiologic Survey on Alcohol and Related Conditions; NESARC; Grant et al., 2004).<ref>Template:Cite book</ref> Traits related to DPD, like most personality disorders, emerge in childhood or early adulthood. Findings from the NESArC study found that 18 to 29 year olds have a greater chance of developing DPD. DPD is more common among women compared to men as 0.6% of women have DPD compared to 0.4% of men.<ref name="Practitioner's Guide to Evidence-Ba"/>

A 2004 twin study suggests a heritability of 0.81 for developing dependent personality disorder. Because of this, there is significant evidence that this disorder runs in families.<ref name="Coolidge,"/>

Children and adolescents with a history of anxiety disorders and physical illnesses are more susceptible to acquiring this disorder.<ref name="Nolen-Hoeksema,">Template:Cite book</ref>

Millon's subtypes

Psychologist Theodore Millon identified five adult subtypes of dependent personality disorder.Template:SfnTemplate:Sfn Any individual dependent may exhibit none or one or more of the following:

Subtype Features Traits
Disquieted dependent Including avoidant features Restlessly perturbed; disconcerted and fretful; feels dread and foreboding; apprehensively vulnerable to abandonment; lonely unless near supportive figures.
Selfless dependent Including masochistic features Merges with and immersed into another; is engulfed, enshrouded, absorbed, incorporated, willingly giving up own identity; becomes one with or an extension of another.
Immature dependent Variant of "pure" pattern Unsophisticated, half-grown, unversed, childlike; undeveloped, inexperienced, gullible, and unformed; incapable of assuming adult responsibilities.
Accommodating dependent Including histrionic features Gracious, neighborly, eager, benevolent, compliant, obliging, agreeable; denies disturbing feelings; adopts submissive and inferior role well.
Ineffectual dependent Including schizoid features Unproductive, gainless, incompetent, meritless; seeks untroubled life; refuses to deal with difficulties; untroubled by shortcomings.

History

The conceptualization of dependency, within classical psychoanalytic theory, is directly related to Sigmund Freud's oral psychosexual stage of development. Frustration or over-gratification was said to result in an oral fixation and in an oral type of character, characterized by feeling dependent on others for nurturing and by behaviors representative of the oral stage. Later psychoanalytic theories shifted the focus from a drive-based approach of dependency to the recognition of the importance of early relationships and establishing separation from these early caregivers, in which the exchanges between the caregiver and the child become internalized, and the nature of these interactions becomes part of the concepts of the self and of others.<ref name=":06"/>
