Cognitive-behavioral therapy for children who have obsessive-compulsive disorder

Obsessive-compulsive disorder (OCD) is a relatively chronic and impairing disorder in children and adolescents. Whereas childhood OCD was largely ignored in the past, major advances in the identification and treatment over the past 20 years have led to a significant upsurge in the prevalence of youngsters seeking treatment for this problem. The present article describes the use of exposure-based cognitive-behavioral therapy (CBT) for the treatment of childhood OCD. Although the phenomenology of OCD is largely consistent across the age span, traditional adult CBT approaches have been modified for use with children and adolescents in order to address those developmental differences that do exist. The case example describes the use of CBT for a child who has OCD and highlights these developmental considerations, including age-appropriate techniques to address family involvement in the disorder and the impact of symptoms on the psychosocial functioning of the patient.     

Depression in comorbid obsessive-compulsive disorder and posttraumatic stress disorder

Previous findings suggested a unique role that depression symptoms might play in the comorbid relationship between obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD). However, the nature of this role remains unclear. Thus, the current study examined ways in which OCD and PTSD symptoms vary as a function of depression, as well as the mediating role of depression in the OCD-PTSD relationship, in 104 individuals seeking treatment for refractory OCD. Findings revealed that depressed individuals in the treatment-refractory OCD sample report higher levels of overall obsessing and greater severity of PTSD. In addition, depression appeared to mediate the relation between OCD and PTSD. Implications of findings are discussed.     

Major depression in panic disorder patients with comorbid social phobia

Rates of depression among panic disorder patients are particularly elevated in patients with comorbid social phobia. However, it is unclear whether this association is specific to social phobia, or whether any comorbid anxiety disorder increases the risk of depression. We assessed 100 panic disorder patients and found a significantly higher incidence of lifetime major depression for panic patients with comorbid social phobia or generalized anxiety disorder (GAD). Panic patients with comorbid social phobia had significantly higher scores on measures of dysfunctional attitudes and lower scores on measures of assertiveness; these variables may mediate the link between social phobia and depression in this population.     

Cognitive behavioral therapy for insomnia enhances depression outcome in patients with comorbid major depressive disorder and insomnia

STUDY OBJECTIVE: Insomnia impacts the course of major depressive disorder (MDD), hinders response to treatment, and increases risk for depressive relapse. This study is an initial evaluation of adding cognitive behavioral therapy for insomnia (CBTI) to the antidepressant medication escitalopram (EsCIT) in individuals with both disorders. DESIGN AND SETTING: A randomized, controlled, pilot study in a single academic medical center. PARTICIPANTS: 30 individuals (61% female, mean age 35 +/- 18) with MDD and insomnia. INTERVENTIONS: EsCIT and 7 individual therapy sessions of CBTI or CTRL (quasi-desensitization). Measurements and results: Depression was assessed with the HRSD17 and the depression portion of the SCID, administered by raters masked to treatment assignment, at baseline and after 2, 4, 6, 8, and 12 weeks of treatment. The primary outcome was remission of MDD at study exit, which required both an HRSD17 score < or =7 and absence of the 2 core symptoms of MDD. Sleep was assessed with the insomnia severity index (ISI), daily sleep diaries, and actigraphy. EsCIT + CBTI resulted in a higher rate of remission of depression (61.5%) than EsCIT + CTRL (33.3%). EsCIT + CBTI was also associated with a greater remission from insomnia (50.0%) than EsCIT + CTRL (7.7%) and larger improvement in all diary and actigraphy measures of sleep, except for total sleep time. CONCLUSIONS: This pilot study provides evidence that augmenting an antidepressant medication with a brief, symptom focused, cognitive-behavioral therapy for insomnia is promising for individuals with MDD and comorbid insomnia in terms of alleviating both depression and insomnia.     

Cognitive behavior therapy in panic disorder and comorbid major depression. A naturalistic study

BACKGROUND: There is a lack of evidence about the effectiveness of cognitive behavior therapies (CBT) in settings of routine clinical care as well as in the treatment of panic and comorbid disorders. METHODS: We investigated a group-oriented CBT approach for 80 patients with panic disorder including 35 patients with current comorbid major depression. Assessments took place 6 months before treatment, at the beginning and end of treatment, and 1 year later. Structured interviews and multiple clinical self-rating scales were used. RESULTS: Panic patients with comorbid major depression showed higher anxiety-specific and nonspecific pathology. The most striking benefits were in reducing avoidance behavior, while improvements concerning catastrophic beliefs were smaller, but still significant. For most self-rating scale results, patients with and without comorbid depression improved to a comparable degree. However, the end-state functioning of patients with panic disorder and current comorbid depression at admission is significantly lower than for patients with panic disorder alone. CONCLUSIONS: The results point to the necessity to develop and improve treatment approaches for patients with comorbidity of panic disorder and current major depression.     

Potential mediators of cognitive-behavioral therapy for adolescents with comorbid major depression and conduct disorder

Several possible mediators of a group cognitive-behavioral therapy (CBT) for depressed adolescents were examined. Six measures specific to CBT (e.g., negative cognitions, engagement in pleasurable activities) and 2 nonspecific measures (therapeutic alliance, group cohesion) were examined in 93 adolescents with comorbid major depressive disorder and conduct disorder who were randomly assigned to the Adolescent Coping With Depression (CWD-A) course or a life skills control condition. Change on the Automatic Thoughts Questionnaire (S. D. Hollon & P. C. Kendall, 1980) appeared to mediate treatment effects on depressive symptoms. Therapeutic alliance by the 3rd session was higher among the CWD-A participants but did not predict reductions in depressive symptoms. Findings suggest that reducing negative thinking may be the primary mechanism through which the CWD-A intervention reduces depression.     

Thought disorder in patients with obsessive-compulsive disorder

We examined the presence of disordered thinking/perception in patients with obsessive-compulsive disorder (OCD). Recently, an obsession model has been proposed, which classifies obsessions into two different subtypes: autogenous obsessions and reactive obsessions (Lee & Kwon, 2003). Based on this model, we hypothesized that OCD patients primarily displaying autogenous obsessions as opposed to reactive obsessions would display more severely disordered thinking/perception. We compared 15 OCD patients primarily displaying autogenous obsessions (AOs), 14 OCD patients primarily displaying reactive obsessions (ROs), 32 patients with schizophrenia (SPRs), and 28 patients with other anxiety disorders (OADs) with respect to thought disorders as assessed by the Comprehensive System of the Rorschach Inkblot Test. Results indicated that both AOs and SPRs displayed more severe thought disorders compared to ROs or OADs. Theoretical and clinical implications are discussed.     

Treatment of major depression in the context of panic disorder.

BACKGROUND: Individuals with major depression frequently have panic attacks, and often panic disorder, but rarely have researchers studied the impact of comorbidity of panic on the outcome of psychological treatment of depression. METHODS: In this study, patients with comorbid panic and depression were first treated with cognitive-behavioral therapy (CBT) for panic. Depression symptoms in this treated group were compared to a group of patients with major depression who were on a minimal therapist contact waitlist. In the second phase of the study, patients in both groups (comorbid and depression-only) were treated with CBT for depression. RESULTS: CBT for panic had little effect on co-existing depression, suggesting a specificity of action for CBT directed at different disorders. In addition, the presence of current or recently remitted panic attacks or agoraphobic avoidance did not interfere with the outcome of CBT for depression. CONCLUSION: These findings stand in contrast to previous studies showing greater linkage between depression and panic in treatment outcome. LIMITATIONS: While there are implications for treatment planning, these conclusions may be limited by the exclusion criteria and the highly structured treatment approach of separating treatment for panic from treatment for depression.     

Memory mood congruency phenomenon in bipolar I disorder and major depression disorder patients

The objective of the present study was to evaluate memory performance in tasks with and without affective content (to confirm the mood congruency phenomenon) in acutely admitted patients with bipolar I disorder (BD) and major depression disorder (MDD) and in healthy participants. Seventy-eight participants (24 BD, 29 MDD, and 25 healthy controls) were evaluated. Three word lists were used as the memory task with affective content (positive, negative and indifferent). Psychiatric symptoms were also evaluated with rating scales (Young Mania Rating Scale for mania and Hamilton Depression Rating Scale for depression). Patients were selected during the first week of hospitalization. BD patients showed higher scores in the word span with positive tone than MDD patients and healthy controls (P = 0.002). No other difference was observed for tests with affective tone. MDD patients presented significantly lower scores in the Mini-Mental State Exam, logical memory test, visual recognition span, and digit span, while BD patients presented lower scores in the visual recognition test and digit span. Mood congruency effect was found for word span with positive tone among BD patients but no similar effect was observed among MDD patients for negative items. MDD patients presented more memory impairment than BD patients, but BD patients also showed memory impairment.     

Phenomenological and comorbid features associated in obsessive-compulsive disorder: influence of age of onset

BACKGROUND: To explore clinical features of symptoms and comorbidity according to the age of onset of patients suffering from obsessive-compulsive disorder (OCD). METHODS: The survey involved collecting data from both patient members of an OCD association, and a sample of 175 OCD patients seen in OCD specialty practice. All the patients (n=617) responded to a questionnaire on family and personal psychiatric OCD history, phenomenological features of OCD and comorbidity. They were classified according to OCD age at onset [group early age of onset (EO): under 15, group late age of onset (LO): older than 15]. RESULTS: A higher percentage of patients from Group LO complained of OCD triggering by factors such as professional difficulties and childbirth (P<0.05); also they more often had (P=0.05) a sudden onset of symptoms. On the other hand, clinical features, such as superstition and magic thoughts, parasite obsessions and repeating, counting, hoarding, tapping/rubbing and collecting compulsions were significantly more frequent (P<0.05) in EO; likewise, history of tics was more frequent in this group. The existence of comorbid depression (at least one episode) did not show any significant difference between groups. However, depression preceding OCD was more frequent in LO. There was no significant difference in treatment response according to age of onset OCD. CONCLUSIONS: The results showed a clear association of EO with obsessions of superstition and parasites, repetitive compulsions and motor and vocal tics, whereas a sudden onset, triggering factors and a more frequent depression preceding OCD characterized LO.     

Symptoms of posttraumatic stress disorder in patients who have had a myocardial infarction

Symptoms of posttraumatic stress disorder (PTSD) and risk factors for recurrent ischemia were evaluated in 65 survivors of a myocardial infarction (MI) at baseline and 6 months afterward. PTSD patients had more uncontrolled cardiovascular risk factors at baseline. Patients with PTSD (N=14) were offered trauma-focused cognitive-behavior treatment (CBT) plus a nonspecific intervention to improve adherence to medical recommendations. Adherence to aspirin improved in recipients of the nonspecific intervention (N=8); PTSD symptoms and cardiovascular risk improved in patients who received CBT (N=6). PTSD may be a treatable risk factor for poor post-MI outcome. Further research is needed to evaluate treatment options.     

Attribution retraining group therapy for outpatients with major depression disorder, generalized anxiety disorder, and obsessive-compulsive disorder: a pilot study

The aim of this present study is to examine the efficacy of attribution retraining group therapy (ARGT) and to compare the responses of outpatients with major depression disorder (MDD),generalized anxiety disorder (GAD) and obsessive-compulsive disorder (OCD).We carried out a prospective uncontrolled intervention study with a 8-weeks of ARGT on sixty three outpatients with MDD,GAD or OCD.Hamilton rating scale for depression,Hamilton rating scale for anxiety,Yale-Brown obsessive-compulsive scale,attribution style questionnaire,self-esteem scale,index of well-being,and social disability screening schedule were administered before and after treatment.Significant improvement in symptoms and psychological and social functions from pre-to posttreatment occurred for all participants.The changes favored MDD patients.Our study suggested that ARGT may improve the symptoms and psychological-social functions of MDD,GAD,and OCD patients.MDD patients showed the best response.     

Impact of comorbid depressive symptoms on nonverbal memory and visuospatial performance in obsessive-compulsive disorder

Introduction. Recent research has suggested that some executive dysfunctions in obsessive-compulsive disorder (OCD) represent an epiphenomenon of comorbid depressive symptoms. The present study investigated whether the impact of comorbid depressive symptoms on cognitive dysfunction in OCD extends to nonverbal memory impairment. Methods. A total of 32 OCD patients and 20 healthy controls took part in the study. Participants were administered a neurocognitive battery with a focus on nonverbal memory and visuospatial functions. Results. While evidence was provided that neurocognitive processes necessitating visuospatial transformation and visuoconstruction are deficient in OCD patients regardless of comorbid depressive symptoms, nonverbal memory dysfunctions were only apparent for patients with elevated scores in the Hamilton Depression (HDRS) Rating Scale (total score S 8). Correlations with subscores of the HDRS revealed that core depressive symptoms are related to nonverbal memory deficits in OCD. Mental rotation, middle discrimination, and position discrimination were found to be unaffected in OCD. Y-BOCS scores, length of illness, onset of illness, number of hospital admissions, and checking compulsions were not associated with neurocognitive disturbances. Conclusions. Nonverbal memory is disturbed in only a subgroup of OCD patients displaying elevated HDRS scores (HDRS S 8). It is claimed but awaits further empirical testing that differences in depression profile across OCD studies have contributed to inconsistencies in prior investigations on neurocognitive functioning in OCD. Our results are questioning the hypothesis that nonverbal deficits are a causal factor for the development of checking compulsions.     

Parents of patients with obsessive-compulsive disorder

Family histories obtained from 27 patients with obsessive-compulsive disorder failed to find a single parent with the disorder. To augment the family history data the Leyton Obsessional Inventory was completed by a subset of 10 patients and by their 20 parents. Although as a group parents showed lower Leyton Obsessional Inventory symptom scores than their obsessional offspring, 3 parents who had not been identified by family history were distinguished by high symptom scores in the absence of significant resistance or interference.     

Preliminary evidence for an association between a dopamine D3 receptor gene variant and obsessive-compulsive personality disorder in patients with major depression.

We have previously reported that the Ser9Gly dopamine D3 receptor (DRD3) polymorphism was associated with increased rates of obsessive-compulsive personality disorder (OCPD) symptomology. We tested the replicability of this association within a further two independent groups of individuals with a history of depression, from a clinical sample (n = 149) and a family study (n = 213). The data from the replication samples and the original sample, within which the association was found, were compiled within a meta-analysis. Although the independent samples did not replicate the original finding, the meta-analysis elucidated significant evidence supporting the association. An individual with Gly/Gly genotype is 2.4 (P = 0.017) times more likely to be diagnosed with OCPD. Male gender was also found to be a significant predictor of OCPD diagnosis (OR = 2.82, P = 0.001). An exploration of an association of DRD3 with Axis I anxiety disorder diagnoses and Temperament and Character Inventory (TCI) traits, in particular persistence, revealed no support for an association. We conclude that DRD3 may contribute to the development of OCPD.     

Repetitive Transcranial Magnetic Stimulation (rTMS) in the treatment of panic disorder (PD) with comorbid major depression

BACKGROUND: Studies suggest that the dorsolateral prefrontal cortex (DLPFC) participates in neural circuitry that is dysregulated in Panic Disorder (PD) and Major Depressive Disorder (MDD). We tested whether low-frequency repetitive Transcranial Magnetic Stimulation (rTMS) could normalize the overactivity of right frontal regions and thereby improve symptoms. METHODS: Six patients with PD and comorbid MDD were treated with daily active 1-Hz rTMS to the right DLPFC for 2 weeks in this open-label trial. RESULTS: Clinical improvements were apparent as early as the first week of treatment. After the second week, 5/6 of patients showed improvements in panic and anxiety, and 4/6 showed a decrease in depression, with sustained improvement at 6 months of follow-up. Right hemisphere resting motor threshold increased significantly after rTMS. LIMITATIONS: Limitations of this study are the open design and the small sample size. CONCLUSIONS: Slow rTMS to the right DLPFC resulted in significant clinical improvement and reduction of ipsilateral motor cortex excitability. Replications in larger sample will help to clarify the relevance of this preliminary data and to define the potential role of right DLPFC rTMS in panic with major depression.     

Factors associated with major depressive disorder occurring after the onset of obsessive-compulsive disorder

BACKGROUND: We aimed to investigate the correlates of major depressive disorder (MDD) occurring after the onset of obsessive-compulsive disorder (OCD). METHODS: Forty-three OCD patients who developed MDD after the onset of OCD (OCD-MDD group) and 67 OCD patients without MDD (non-MDD, NMDD group) were compared with regard to sociodemographic characteristics, clinical history, symptom severity, types of obsessions and compulsions, insight degree, comorbid axis I and axis II diagnosis and quality-of-life level. RESULTS: The OCD-MDD group scored significantly higher on measures of obsessions, compulsions and depression severity than did the NMDD. Significantly more aggressive obsessions were identified in the OCD-MDD group than in the NMDD group. The OCD-MDD group was also significantly more likely than the NMDD group to have generalized anxiety disorder (GAD). There was no significant difference in the rate of personality disorders between the groups. The OCD-MDD group reported significantly lower levels of quality of life (QOL) in the domains of physical health, psychological health and social relationships. Depression severity was associated with obsession but not with compulsion severity. In a logistic regression model, obsession severity, presence of GAD and aggressive obsessions emerged as the factors associated with the occurrence of MDD. LIMITATIONS: To exclude ineligible patients, we gathered the information about past mood episodes cross-sectionally. CONCLUSIONS: These results suggest that psychopathological processes mediated by specific obsessions as well as excessive anxiety and worries may render the neurocircuities more vulnerable to the development of MDD. The occurrence of MDD in OCD cannot sufficiently be explained as a secondary complication to the disability of OCD.
