DSM criteria Flashcards
anorexia nervosa - criteria
A. Restriction of energy intake relative to requirements, leading to a significantly low body weight in the context of age, sex, developmental trajectory, and physical health
B. Intense fear of gaining weight or of becoming fat, or persistent behavior that interferes with weight gain, even though at a significantly low weight.
C. Disturbance in the way in which one’s body weight or shape is experienced, undue influence of body weight or shape on self-evaluation, or persistent lack of recognition of the seriousness of the current low body weight
anorexia nervosa
criteria - remission & severity
Remission:
- Partial if criteria A (i.e., low body-weight) has not been met for a sustained period, but either criteria B (i.e., fear of gaining weight) or criteria C (i.e., disturbed self-perception) is still met
- Full if none of the criteria are met for a sustained period
Severity specifier: minimum level of severity is based on BMI for adults
- Mild if equal or less to 17
- Moderate if 16-16.99
- Severe if 15-15.99
- Extreme if less than 15
anorexia nervosa
diagnostic features
Crit A: sig low weight - as BMI for adults and BMI percentile for children
Crit B: sig fear of gaining weight - due to distortions, concern about weight gain may increase as weight falls
- Some may not recognize/acknowledge a fear of weight gain
- In absence of fear other markers should be used
Crit C: significance of body weight and shape distorted - heterogeneity in how this cognition operates within individuals
anorexia nervosa
associated features supporting diagnosis
The pathological behaviors that occur in AN can onset potentially life-threatening medical conditions (e.g. nutritional deficiency)
when seriously underweight, many AN indiv have depressive signs and symptoms
obsessive-compulsive features - both food and non-food related
other features:
- concerns about eating in public
- feelings of ineffectiveness
- strong need to be in control
- inflexible thinking
- limited social spontaneity
- overly restrained emotional expression
the binge-eating/purging type have higher rates of impulsivity and are more likely to abuse substances
anorexia nervosa
other info
(prevalence, development/course, risk, comorbidity)
Prevalence: the 12-month prevalence among young females is approximately 0.4% (2013)
- gender gap is 10:1
Development and course
- Commonly begins during adolescence / young adulthood
- Onset associated with stressful life event
- Course is highly variable
- Changed eating prior to full onset
- Some (most), people never fully recover after a single episode
- Mortality is about 5% - from medical complications due to not eating and suicide
Risk and prognostic factors:
- Temperamental: indiv who develop anxiety disorders or display obsessional traits in childhood are at increased risk
- Environmental: associated with cultures and settings in which thinness is valued
Genetic and physiological: increased risk in first-degree relatives;
Comorbidity:
- Bipolar
- MDD
- Anxiety
- SUD in the binge-eating/purging type
bulimia nervosa - criteria
A. Recurrent episodes of binge eating. An episode of binge eating is characterized by both of the following:
1. Eating, in a discrete period of time (e.g., within any 2-hour period), an amount of food that is definitely larger than what most individuals would eat in a similar period of time under similar circumstances.
2. A sense of lack of control over eating during the episode (e.g., a feeling that one cannot stop eating or control what or how much one is eating).
B. Recurrent inappropriate compensatory behaviors in order to prevent weight gain, such as self-induced vomiting; misuse of laxatives, diuretics, or other medications; fasting; or excessive exercise.
C. The binge eating and inappropriate compensatory behaviors both occur, on average, at least once a week for 3 months.
D. Self-evaluation is unduly influenced by body shape and weight.
E. The disturbance does not occur exclusively during episodes of anorexia nervosa
bulimia nervosa
criteria - remission and severity
Severity: the minimum level of severity is based on the frequency of inappropriate compensatory behaviors
- Mild: An average of 1–3 episodes of inappropriate compensatory behaviors per week.
- Moderate: An average of 4–7 episodes of inappropriate compensatory behaviors per week.
- Severe: An average of 8–13 episodes of inappropriate compensatory behaviors per week.
- Extreme: An average of 14 or more episodes of inappropriate compensatory behaviors per week.
Remission:
- In partial remission: after full criteria met, some, but not all, criteria not met for sustained time
- In full remission: no criteria for sustained time
bulimia nervosa
diagnostic features
3 essential features: Criterion A, Criterion B, and Criterion D
- To diagnose, at least once per week for 3 months (crit C)
Main trigger is negative affect - others incl: interpersonal stressors, dietary restraint, boredom
- Binging minimizes negative affect in the short-term, but has delayed consequences
Body weight/shape determines self-esteem (CritD)
Associated features supporting diagnosis:
- Bulimics are typically within normal weight or overweight (BMI above 30)
- When not binging, bulimics restrict their calorie intake
- Amenorrhea (i.e., menstrual irregularity) is common among females with bulimia
- Can lead to severe physical complications
bulimia nervosa
other info
(prevalence, development/course, risk, comorbidity)
Prevalence: 12-month prevalence among young females is 1%-5%;
- Highest in young adults - onset peaks in later adolescence
- Gender gap 10:1
Development and course:
- Onset before puberty or after 40 is uncommon
- Frequently begins during / after an episode of dieting to lose weight
- SLEs
- Disturbed eating persists for at least several years in most clinical samples
- Course is chronic or intermittent, with periods of remission
- Elevated risk of mortality (all-cause and suicide): 2%
- Some cross-over from BN to BED + few from BN to AN
Risk and prognostic criteria
- Temperamental - weight concerns, low self-esteem, depressive symptoms, SAD, and overanxious disorder of childhood
- Environmental - internalization of a thin body ideal + childhood sexual/physical abuse
- Genetic and physiological - childhood obesity and early pubertal maturation + familial transmission and genetic vulnerabilities
Comorbidity - generally common, with most having at least one other mental disorder and many experiencing multiple ones
- depressive and bipolar disorders
- anxiety
- Substance use
- Personality disorders, most often BPD
BED - criteria
(+severity)
A. Recurrent episodes of binge eating
B. The binge-eating episodes are associated with three (or more) of the following:
1. Eating much more rapidly than normal
2. Eating until feeling uncomfortably full
3. Eating large amounts of food when not feeling physically hungry
4. Eating alone because of feeling embarrassed by how much one is eating
5. Feeling disgusted with oneself, depressed, or very guilty afterward.
C. Marked distress regarding binge eating is present.
D. The binge eating occurs, on average, at least once a week for 3 months.
E. The binge eating is not associated with the recurrent use of inappropriate compensatory behavior as in bulimia nervosa and does not occur exclusively during the course of bulimia nervosa or anorexia nervosa.
Severity: The minimum level of severity is based on the frequency of episodes of binge eating
- Mild: 1–3 binge-eating episodes per week.
- Moderate: 4–7 binge-eating episodes per week.
- Severe: 8–13 binge-eating episodes per week.
- Extreme: 14 or more binge-eating episodes per week
BED
diagnostic features
Diagnostic features - almost the same as bulimia but without purging
Individuals with BED are typically ashamed of their eating problems and attempt to conceal their symptoms
Binging is usually done alone
Triggered by negative affect
Associated features supporting diagnosis:
- Reliably associated with being overweight/obesity in treatment-seeking individuals
- However, distinct from obesity - BED eat more, higher impairment, lower QOL, more subj distress, and higher psychiatric comorbidity
BED
other info
(prevalence, development/course, risk, comorbidity)
Prevalence: 12-month prevalence is 1.6% for females and 0.8% for males
- Gender gap is smaller than in bulimia
- Similar across ethnic groups
Development and course
- Little known about development
- Binge-eating is common in adolescent and college-age samples
- Dieting follows the development of binge eating in many BED indiv - in contrast to bulimia where dieting precedes binging
- Typically begins in adolescence and young adulthood, but can begin in later adulthood;
- Remission rates for BED higher than for bulimia and anorexia
- Cross over to other EDs is uncommon
Risk and prognostic factors
- Genetic and physiological - BED appears to run in families
Comorbidity
- bipolar, depressive & anxiety disorders
- To a lesser degree, substance use disorders
pica - criteria
A persistent eating of nonnutritive, nonfood substances over a period of at least 1 month
B. this is inappropriate to the developmental level of the individual
C. it is not part of a cultural/socially normative practive
D. if it occurs in the contenxt of another mental disorder or a medical condition, it is sufficiently severe to warrant additional clinical attention (ie autism, intellectual disability, schizophrenia)
rumination disorder - criteria
A. repeated regurgiation (ie swalled food going up (reflux)) over a period of at least 1 month
- regurgiated food may be re-chewed, re-swallowed, or spit out
B. this is not attributable to an associated gastrointenstinal or other medical conditon
C. this doesn’t occur during other eating disorders
D. if it is in a context of another mental/physical disorder, the symptoms are sufficiently severe to warrant attention
avoidant/restrictive food intake disorder - criteria
A. an eating disturbance (ie apparent lack of interest in food/eating, avoidance of food, concern about eating) as manifested by persistent failure to meet appropriate nutritional and/or energy needs associated with one (or more) of the following:
1. significant weight loss (or failure to achieve expected weight gain in children)
2. significant nutritional deficiency
3. dependence on external feeding/oral supplements
4. marked interference w/psychosocial functioning
B. not better explained by lack of available food / culturally sanctioned practice
C. does not occur during AN/BN, and there is no evidence of a disturbance in the way in which one’s body weight is experienced
D. not attributable to another medical/mental condition
sexual dysfunctions (in general)
a heterogeneous group of disorders that are typically characterized by a clinically sig disturbance in a person’s ability to respond sexually/experience sexual pleasure
Subtypes:
- Lifelong = a sexual problem that has been present from first sexual experiences
- Acquired = sexual disorders that develop after a period of relatively normal sexual function
- Generalized = SD that are not limited to certain types of stimulation, situations, or partners
- Situational = SD that only occur with certain types of stimulation, situations, or partners
Factors to consider during assessment:
1. Partner factors
2. Relationship factors
3. Individual vulnerability factors - i.e. stressors & comorbidities
4. Cultural/religious factors
5. Medical factors relevant to prognosis, course, or treatment
delayed ejaculation - criteria
A. either of the following symptoms must be experienced on almost all or all occasions (approximately 75%–100%) of partnered sexual activity and without the individual desiring delay:
1. marked delay in ejaculation
2. marked infrequency or absence of ejaculation
B. Crit A symptoms have persisted for a minimum duration of approximately 6 months
C. Crit A symptoms cause clinically significant distress in the individual
D. Not better explained by a nonsexual mental disorder or as a consequence of severe relationship distress/other sig stressors; not due to medication/substance or another mental condition
specify whether:
- lifelong/acquired
- generalized/situational
specify severity:
- mild
- moderate
- severe
delayed ejaculation
diagnostic features
Difficulty/inability to ejaculate despite the presence of adequate sexual stimulation and the desire to ejaculate
Usually involves partnered sexual activity
No precise definition of ‘delay’ as there is nonconsensus as to what constitutes a reasonable time to reach orgasm or what is unacceptably long for men
Associated features supporting diagnosis:
- Partner may report prolonged thrusting to achieve orgasm to the point of exhaustion/genital discomfort and then ceasing efforts
- Some avoid sexual activity bc of the pattern of delay
- Some report feeling less sexually attractive
- The 5 factors should be considered
delayed ejaculation
other info
Prevalence: least common male sexual complaint - less than 1% of men
Development and course:
- Minimal evidence for acquired subtype
- An increase in prevalence around age 50 which continues
Risk and prognostic factors:
- Age-related loss of the fast-conducting peripheral sensory nerves
- Age-related decreased sex steroid secretion
Culture-related diagnostic issues - most common among men in Asian populations
Functional consequences
- May contribute to difficulties in conception
- Associated w/considerable distress in one/both partners
Differential diagnosis:
- Another medical condition: a situational aspect is suggestive of a psychological basis for the problem - e.g., men who can ejaculate during sex with one but not with another
- Substance/medication use - pharmacological agents can cause ejaculatory problems
- Dysfunction with orgasm - ascertain whether the complaint concerns delayed ejaculation or the sensation of orgasm, or both
Comorbidity: some evidence that it may be comorbid with severe MDD
erectile disorder - criteria
A. At least one of the 3 following symptoms experienced on 75-100% of occasions of sexual activity (in situational or generalized contexts)
1. Marked difficulty in obtaining an erection during sexual activity
2. Marked difficulty in maintaining an erection until the completion of sexual activity
3. Marked decrease in erectile rigidity
B. Symptoms persists for minimum 6 months
C. Symptoms cause clinically sig distress
D. Not better explained by a nonsexual mental disorder, etc.,
Specify if:
Lifelong / acquired
Generalized / situational
Specify severity from mild to severe
erectile disorder
diagnostic features
The key feature is the repeated failure to obtain or maintain erection during partnered sexual activities
May be specific or generalized
Associated features supporting diagnosis:
- Men may present low self-esteem, low self-confidence, and a decreased sense of masculinity, and may experience depressed affect
- Decreased sexual desire / satisfaction in partner
- Fear / avoidance of future sexual encounters
- The five factors should be assessed
erectile disorder
other info
Prevalence: strong age-related increase, particularly after age 60
Development and course
- Erectile failure on first sexual attempt has been found to be related to having sex w/a previously unknown partner, substance use, not wanting to have sex and peer pressure
- Minimal evidence that erectile dysfunction spontaneously remits without professional intervention
- Acquired erectile disorder is likely to be persistent/chronic in most men
Risk and prognostic factors:
- Temperamental: neuroticism, submissive personality traits, alexithymia (deficits in cog processing of emotions)
- Course modifiers: age, smoking tobacco, lack of physical exercise, diabetes, and decreased drive
Diagnostic markers:
- Measuring erections during sleep - helps differentiate organic from psychogenic erectile problems
- if one gets erections while sleeping but not with a partner than its most likely psychological
Differential diagnosis
- Nonsexual mental disorders: MDD - erectile disorder accompanying severe depressive disorder may occur
- Normal erectile function
- Substance medication use
- Another medical condition
- other sexual dysfunctions
Comorbidity: other sexual diagnoses + anxiety and depressive disorders
male hypoactive sexual desire disorder - criteria
A. Persistently or recurrently deficient (or absent) sexual/erotic thoughts or fantasies and desire for sexual activity; the judgment of deficiency is made by the clinician, taking into account factors that affect sexual functioning, such as age and general/sociocultural contexts of the individual’s life
B. Symptoms persist for a minimum dura)on of approximately 6 months
C. Crit A symptoms cause clinically sig distress in the individual
D. Not better explained by a nonsexual mental disorder or as a consequence of severe relationship distress/other sig stressors; not due to medication/substance or another mental condition
Specify whether:
Lifelong / acquired
Generalized / situational
Specify severity
male hypoactive sexual desire disorder
diagnostic features
Interpersonal context must be taken into account
Both low/absent desire for sex and deficient/absent sexual thoughts must be present for a diagnosis
Variation in how desire is expressed
Associated features supporting diagnosis
- Sometimes associated with erectile/ejaculatory problems - e.g., erectile dysfunction may lead one to stop being interested in sex
- Sexual activities may sometimes occur even in the presence of low sexual desire
- Relationship-specific-preferences must be taken into account
