2 DSM-5 Criteria Characterized by uncontrollable and excessive worrying/anxiety for more days than not for at least 6 months about several events and activities causing significant distress/impairment in functioning Anxiety/worry is out of proportion to actual likelihood or impact of event/activity Worries are more excessive, more distressing, have longer duration, and occur more spontaneously than those experienced by non-pathological individuals Three of the six following symptoms must be present for diagnosis in adults; Only one symptom must be present for children: Restlessness or feeling on edge Easily fatigued Difficulty concentrating or mind going blank Irritability Muscle Tension Difficulty sleeping (DSM-5, 2013)

3 DSM-5 Criteria Worries and distress must not be attributable to substances or other medical conditions. Cannot be better explained by another mental disorder (e.g., another anxiety disorder, worry about weight gain in anorexia, delusional beliefs in schizophrenia) Somatic symptoms include sweating, nausea, diarrhea, IBS, trembling, soreness, aches Symptoms of autonomic hyperarousal, such as increased heart rate, shortness of breath, dizziness, are less prominent in GAD than other anxiety disorders (e.g., panic disorder) Genetic factors: account for 1/3rd of the risk of GAD, including overlap of neuroticism Temperamental factors: Behavioral inhibition, negative affectivity/neuroticism, harm avoidance Environmental factors: DSM does not identify any environmental factors for making diagnosis, although childhood adversity and parental overprotection may be associated with GAD (DSM-5, 2013)

4 DSM-5 in Children Children with GAD often worry about competence or quality of performance, especially relating to school and sports, and/or catastrophic events (e.g., earthquakes) Children may be overly conforming, perfectionistic, unsure of themselves, and/or redo tasks because of excessive dissatisfaction DSM claims that GAD may be over-diagnosed in children and emphasizes making sure to rule out alternative diagnoses such as Social Anxiety Disorder, Separation Anxiety Disorder, and Obsessive Compulsive Disorder

5 DSM-5 Schematic GAD Core Features worry, restlessness/feeling on edge, fatigue, difficulty concentrating, irritability, muscle tension, difficulty sleeping Genetic Factors Temperamental Factors behavioral inhibition, negative affectivity, harm avoidance Somatic Symptoms sweating, nausea, diarrhea, trembling, soreness, startled responses, IBS Secondary Features functional impairment, distress about competence and quality of performance, unsure of self, dissatisfaction Neuroticism

6 GAD Child Example “John is a 10-year-old fifth grader who always seems to be worrying. He constantly worries about such things as his grades, being good enough at baseball, his appearance, arriving on time to classes and activities, and the health of his mother and father. John worries about these things almost everyday and has been worrying like this for almost a year now. When he worries he often feels restless, becomes TIRED and irritated easily, has trouble concentrating, and has difficulty falling asleep. In fact, John worries so much that he just cannot seem to have fun or concentrate on his school work anymore. For example, while planning his 10th birthday, John worried for two weeks about whether his friends would come, whether it would rain, whether there would be enough food, whether everyone would have fun, etc.” -Society of Clinical Child and Adolescent Psychology, Division 53, American Psychological Association

7 History First made appearance in the DSM-III in Only 1 month symptom duration necessary The symptom of worry was not required for diagnosis, but was listed as one of the 4 possible symptoms in criteria Until the DSM-III-R (1987), GAD was not defined well enough and was used as an “other” diagnostic category for individuals who did not fit diagnosis of other anxiety disorders (Rowa, Hood, Antony, 2013)

8 Onset/Prevalence Onset is rarely before adolescence. Onset is less common in childhood than other anxiety disorders (e.g., Social Anxiety Disorder, Separation Anxiety Disorder) Median onset of GAD is 30 years, but age at onset is spread over a broad range Those with GAD report feeling anxious/nervous their whole lives and symptoms are chronic across the lifespan 12 month prevalence is 0.9% in adolescents and 2.9% in adults Lifetime morbid risk is 9% Female to male ratio of prevalence is 2:1 (DSM-5, 2013) 5.7% Lifetime Prevalence (Kessler, et al., 2005) The earlier the onset, the higher the symptoms severity and comorbidity to other disorders (Campbell, Brown, & Grisham, 2003)

9 Cognitive Processes Children with GAD exhibit: probability overestimation- thinking a feared consequence is more likely to occur than it truly is catastrophizing- assuming an outcome will be much more unmanageable than it actually is (Suarez & Bell-Dolan, 2001) Anxious children: Interpret ambiguous events as being negative and/or dangerous more often than externalizing, borderline, or control children Underestimate their competencies and view themselves as being less influential than control children (Bogels & Zigterman, 2000)

10 Comorbidity Commonly comorbid with other anxiety disorders and depression in women and substance use in males Based on the DSM-5’s criteria, GAD symptoms should be present before an onset or after remission of depression in order for a comorbid diagnosis (DSM-5, 2013) 90.4% lifetime comorbidity in people with a history of GAD (National Comorbidity Survey; Wittchen, Zhao, Kessler & Eaton, 1994)

11 Comorbidity and Risk Factors of GAD Beesdo, Pine, Lieb, 2010: Longitudinal community study in Germany Investigated developmental factors and comorbidity of GAD with other anxiety disorders and depression Looked into parental, temperamental (e.g., behavioral inhibition), and environmental factors 3021 participants (14-24 years) at baseline. GAD diagnosis (n = 106). Follow-up at 3 time points Results showed strong associations with panic and phobias (odds ratio, 7.06; 95% CI, ; p <.001) and depressive disorders (odds ratio, 4.44; 95% CI, ; p <.001) Phobias and panic disorder, GAD, and depressive disorders significantly predicted the onset of one another Highest HRs emerged for GAD predicting anxiety disorders (HR, 4.14) and anxiety disorders predicting GAD (HR, 5.05)

12 (Beesdo, Pine, Lieb, 2010)

14 Comorbidity and Risk Factors of GAD Comorbidity: Panic and phobias Depressive Disorders Genetic Factors: 29% of those with GAD, had parents with GAD (HR=3.77, p <.001) 15% had parents with an anxiety disorder, but no depressive disorder 22% had parents with a depressive disorder but no anxiety disorder (HR=1.77, p <.03) 8% had parents with both Environmental Factors: 28% had experienced childhood separation events (HR=2.44, p <.001)- not included in DSM-5 3% had Parental Overprotection (HR=1.48, p <.02) –not included in DSM-5.5% had Dysfunctional family functioning (HR=1.48, p <.02) - not included in DSM-5 Temperamental Factors: Only 6% showed harm avoidance (HR=1.69, p <.001) – matches up with DSM-5 Only.5% showed behavioral inhibition (HR=1.97, p <.001) - matches up with DSM-5 Only 4% showed reward dependence (HR=.84, p <.02)

15 Temperamental Factors and GAD Behavioral Inhibition: tendency for children to be afraid or anxious of new situations, causing them to be distressed and sometimes withdraw. Common symptom of social anxiety. Harm Avoidance: characterized by excessive worrying, pessimism, shyness, and being fearful and doubtful Negative Affectivity/Neuroticism: experience of negative emotions and poor self-concept/characterized by anxiety, fear, moodiness, worry, frustration, jealousy, and loneliness

16 Temperamental Factors- Behavioral Inhibition Followed up from 4 months to 7.5 years Direct observations from children High reactive and inhibited infants are at a higher risk for having anxious symptoms later in development Highly reactive at 4 months: Frequent vigorous motor activity Arching of the back Fretting and crying (Kagan & Snidman, 1999)

17 Temperamental Factors- Behavioral Inhibition Only.5% showed behavioral inhibition (Beesdo, Pine, Lieb, 2010) Longitudinal study of behavioral inhibition as a predictor of anxiety disorders in children 3 year follow-up Children have higher rates of childhood-onset anxiety disorders Behavioral inhibition may present familial risk for anxiety disorders (Rosenbaum, et. al, 1993)

18 Temperamental Factors- Harm Avoidance 6% of children with GAD exhibited harm avoidance (Beesdo, Pine, Lieb, 2010) In a sample of exclusively Caucasian children (N = 334, M = 10.4 years): Harm avoidance scores were shown to be significantly predictive of GAD diagnoses in exclusively Caucasian children (AUC =.791, P <.001) There were also children with high harm avoidance scores who did not qualify for a diagnosis of GAD (Rettew, Doyle, Kwan, Stanger, & Hudziak, 2006)

19 Temperamental Factors- Neuroticism Hale, Klimstra, & Meeus, 2010: Study of the GAD symptom of worry in relation to neuroticism 5 year longitudinal study Early adolescents (n = 923, M = 12.4, 49% girls) and middle (n = 390, M = 16.7, 57% girls) adolescents from general population Results: Neuroticism measured on Goldberg’s Big Five Questionnaire GAD symptoms measured on Screen for Child Anxiety Related Emotional Disorders (SCARED) GAD and neurotic symptoms both stable over 5 years Were related at every time point and both predicted the other across time points

20 The pathway from GAD symptoms to neuroticism were stronger than neuroticism to GAD symptoms (Hale, Klimstra, & Meeus, 2010)

21 Neurobiological Factors GAD known to affect fear networks in brain Show dysregulation in central fear circuits, including: anterior limbic network (ALN) connections between amygdala and ventromedial prefrontal cortex area ventrolateral prefrontal cortex (VLPFC) rostal insula (ACC) subgenual and rostral anterior cingulate cortex (Yamasaki, LaBar, & McCarthy, 2002) Serotonergic area is linked to the ALN, which is why SSRIs are effective in medicating children with GAD SSRIs increase activity in VLPFC in children Dysregulation in these areas can also be seen in those who have other anxiety disorders and major depressive disorder, which GAD is often comorbid with (Strawn, Wehry, DelBello, Rynn, & Strakowski, 2012)

24 Neurobiological Factors- Amygdala Roy et al., 2013: There is evidence that GAD may affect functioning in the amygdala Investigated amygdala network dysfunction with resting state fMRI scans 15 adolescents with GAD, 20 control adolescents Results: Adolescents with GAD showed disruptions in amygdala-based intrinsic functional connectivity networks, including regions in medial prefrontal cortex, insula, and cerebellum Adolescents with GAD displayed alterations in amygdala circuits involved in emotion processing, which is similar to findings in adults, as well as, in fear processing and the coding of interoceptive states. Anxiety severity scores and amygdala functional connectivity with insula and superior temporal gyrus were positively related for adolescents with GAD Evidence of overlap of the right basolateral and centromedial amygdala networks in the adolescents with GAD

25 (Roy et al., 2013)

26 Environmental and Family Factors Hale, Engels & Meeus, 2006: Examined perceived parenting styles and GAD symptoms Found positive association between perceived parental alienation and rejection with GAD symptoms in adolescents Hale, Klimstra, Branje, Wijsbroek, & Meeus, 2013: Longitudinal community study 923 adolescents (M = 12.4 years; 49.3% girls, 50.7% boys) SEM conducted to examine relationship between perceived parental interactions (parental rejection, over-control, attachment behaviors)and adolescents’ GAD symptoms GAD symptoms significantly predicted perception of parental interactions

27 Hale, Klimstra, Branje, Wijsbroek, & Meeus, 2013

28

29 Diagnostic measures Generalized Anxiety Disorder Questionnaire (GADQ-IV; Newman et al., 2002) Y/N 2 questions with a severity scale 1 open-ended question on frequent worries Strong psychometric properties Anxiety Disorders Interview Schedule for Children/Parents (ADIS C/P; Silverman & Albano, 1996) Semi-structured interview

30 Treatment of GAD Division 53 recognizes the following empirically supported treatments for working in relieving general symptoms of anxiety in young people: Individual CBT Group CBT (without parents) Group CBT with parents Social skills training Exposure treatment

31 Treatment- CBT Empirically effective Cognitive-Behavioral Therapy: Includes components of: psychoeducation, relaxation training, monitoring cues and targets of worrying, imaginal exposure, cognitive restructure

32 Treatment- TBT Clementi & Alfano, 2010: Kids with GAD have found to have sleep problems as well New intervention: Targeted Behavioral Therapy (TBT; Alfano, 2010) targets anxiety and sleep problems 4 children: 2 boys, 2 girls with GAD (7–12 years) TBT: sleep intervention (sleep improvement strategies) systematic desensitization for reducing intolerance of uncertainty In vivo exposures for anxiety Anxiety and sleep were rated weekly during 4-week baseline, 14-weeks of treatment, and followed up at post-treatment and 3-months follow up Therapists were blind to all weekly ratings

33 Treatment- TBT Results: Anxiety Disorders Interview Schedule for Children/Parents (ADIS C/P; Silverman & Albano, 1996). Semi-structured No child had a GAD diagnosis at follow-up

34 Treatment- SSRIs Rynn, Siqueland, & Rickels, children/adolescents with primary diagnosis of GAD (5-17 years) Anxiety Disorders Interview Schedule for Children—Revised 9 week double-blind, randomly selected treatment: 11 given SSRI, Sertraline (25 mg first week, 50 mg for duration) 11 given placebo Weekly visits to check-up on medication effects and gather assessment of symptoms Results: From week 4 onward, scores improved for SSRI group on the Hamilton Anxiety Rating Scale (HARS) and Clinical Global Impression Severity (CGI) 10/11 kids on Sertraline rated themselves as “improved” on the CGI at week 9 Only 1/11 kid on placebo rated self as “improved” on the CGI at week 9

35 Rynn, Siqueland, & Rickels, 2001

36 Treatment-Type and Results Children randomly assigned to medication (Sertraline, Venlafaxine ER, Fluoxetine, or Fluvoxamine), CBT, placebo, or combination of medication and CBT for either 8, 9, or 12 weeks Anxiety scores on the Pediatric Anxiety Rating Scale (PARS) or Hamilton Anxiety Rating Scale (HAM-A) Significant improvements of anxiety scores in children who received: Treatment of SSRI (Sertraline) for 9 weeks Combination treatment of Sertraline and CBT for 12 weeks
