Long-term outcome of patients with dysthymia and panic disorder: a naturalistic 9-year follow-up study

Predictors of persistence of anxiety disorders across the lifespan: a systematic review

Despite the substantial disease burden of anxiety disorders, physicians have a poor understanding of factors that predict their typical persistent course. This systematic review of predictors of persistent anxiety disorders covered 48 studies with 29 690 patients diagnosed with an anxiety disorder that were published in PubMed, PsycINFO, and Web of Science between Jan 1, 1980 (introduction of DSM-III), and Dec 1, 2019. We also compared predictors between children, adolescents, adults, and older adults (ie, ≥55 years). A persistent course was primarily predicted by clinical and psychological characteristics, including having panic attacks, co-occurring personality disorders, treatment seeking, poor clinical status after treatment, higher severity and longer duration of avoidance behaviour, low extraversion, higher anxiety sensitivity, and higher behavioural inhibition. Unlike disorder onset, sociodemographic characteristics did not predict persistence. Our results outline a profile of patients with specific clinical and psychological characteristics who are particularly vulnerable to anxiety disorder persistence. Clinically, these patients probably deserve additional or more intensive treatment to prevent development of chronicity.

Thirty-year outcome of anxiety and depressive disorders and personality status: comprehensive evaluation of mixed symptoms and the general neurotic syndrome in the follow-up of a randomised controlled trial

BACKGROUND

Cohort studies of the long-term outcome of anxiety, depression and personality status rarely join together.

METHODS

Two hundred and ten patients recruited with anxiety and depression to a randomised controlled trial between 1983 and 1987 (Nottingham Study of Neurotic Disorder) were followed up over 30 years. At trial entry personality status was assessed, together with the general neurotic syndrome, a combined diagnosis of mixed anxiety-depression (cothymia) linked to neurotic personality traits. Personality assessment used a procedure allowing conversion of data to the ICD-11 severity classification of personality disorder. After the original trial, seven further assessments were made. Observer and self-ratings of psychopathology and global outcome were also made. The primary outcome at 30 years was the proportion of those with no Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnosis.Data were analysed using multilevel repeated measures models that adjusted for age and gender. Missing data were assumed to be missing at random, and the models allowed all subjects to be included in the analysis with missing data automatically handled in the model estimation.

RESULTS

At 30 years, 69% of those with a baseline diagnosis of panic disorder had no DSM diagnosis compared to 37-47% of those with generalised anxiety disorder, dysthymia or mixed symptoms (cothymia) (p = 0.027). Apart from those with no personality dysfunction at entry all patients had worse outcomes after 30 years with regard to total psychopathology, anxiety and depression, social function and global outcome.

CONCLUSIONS

The long-term outcome of disorders formerly called 'neurotic' is poor with the exception of panic disorder. Personality dysfunction accentuates poor recovery.

Pathways towards different long-term outcomes after naturalistic psychotherapy

This study suggests some potential pathways leading towards maintained gains or further growth versus deterioration after naturalistic psychotherapy with experienced clinicians. This is explored in a way that transcends specific theoretical orientations. Sixteen therapies, all showing reliable improvement on Outcome Questionnaire 45.2 (OQ-45) at treatment termination but varying in later post-therapy development, were included in this study. Building on previous content and correlational analyses, individual cases were explored qualitatively in search for developmental patterns of potential relevance for long-term outcome. Patterns re-emerging across several cases were described in light of the OQ-45 trajectories of clients providing them. Six pathways, associated with different long-term outcomes, emerged. Four of these, "Reflective route towards regulation of affects," "Gaining autonomy through a secure holding relationship," "Opening up as a new relational/emotional experience," and "Lasting acceptance of «reality»," re-emerged in clients showing maintained/growing treatment effects. Two pathways, entitled "Residual problems grow and overshadow progress" and "Core problems remain beneath superficial change," seemed linked to deterioration after termination of therapy. We suggest the former pathways as some possible routes towards enduring good outcome, and the latter as some patterns to avoid when trying to secure therapy gains will not be only temporary.

EMDR in the Treatment of Panic Disorder With Agoraphobia: A Case Description

The results of preliminary research investigating the application of eye movement desensitization and reprocessing (EMDR) treatment in panic disorder and panic disorder with agoraphobia suggests that reprocessing of past traumas produces significant reduction of anxiety and consequently, remission from panic attacks and avoidance behavior. This article describes the case study of a 30-year-old working professional where EMDR treatment, used to target early childhood traumas, led to reduction in symptoms of panic disorder with agoraphobia. Panic attacks diminished after 17 sessions of EMDR treatment, which followed Leeds’s treatment model. Treatment gains were maintained 5 years after termination. The study shows the value of solid preparation work, and of addressing the current triggers and recent events, before targeting historical traumas. EMDR worked as a first-line treatment to resolving the roots of the panic attacks, suggesting that the resolution of traumatic childhood memories can make a significant difference to current symptoms of panic disorder with agoraphobia.

Paroxetine in the treatment of dysthymic disorder without co-morbidities: A double-blind, placebo-controlled, flexible-dose study

Few published studies have evaluated selective serotonin reuptake inhibitors in dysthymia without current co-morbid major depression. In this 12-week study, 40 dysthymic patients were randomly assigned to either placebo (n=19) or 20-40 mg/day of paroxetine (n=21). At endpoint, the paroxetine group showed significantly greater improvement on the Clinical Global Impression Scale, Beck Depression Inventory, and Quality of Life Enjoyment and Satisfaction Questionnaire (p<0.05), and a trend to superiority over placebo on the Hamilton Depression Rating Scale. Response and remission were significantly higher with paroxetine than placebo (p<0.05). There were no significant differences in drop out rates or frequency of adverse effects, except for excessive sweating (greater with paroxetine, p=0.04). Reporting of multiple side effects was also higher with paroxetine than with placebo (p=0.02). Paroxetine is more effective than placebo in improving symptoms and quality of life in dysthymia, and is generally tolerable.

Comorbidity of personality disorders in anxiety disorders: a meta-analysis of 30 years of research

BACKGROUND

A comprehensive meta-analysis to identify the proportions of comorbid personality disorders (PD) across the major subtypes of anxiety disorders (AD) has not previously been published.

METHODS

A literature search identified 125 empirical papers from the period 1980-2010 on patients with panic disorders, social phobia, generalised anxiety, obsessive-compulsive (OCD) and post-traumatic stress disorder (PTSD). Several moderators were coded.

RESULTS

The rate of any comorbid PD was high across all ADs, ranging from .35 for PTSD to .52 for OCD. Cluster C PDs occurred more than twice as often as cluster A or B PDs. Within cluster C the avoidant PD occurred most frequently, followed by the obsessive-compulsive and the dependent PD. PTSD showed the most heterogeneous clinical picture and social phobia was highly comorbid with avoidant PD. A range of moderators were examined, but most were non-significant or of small effects, except an early age of onset, which in social phobia increased the risk of an avoidant PD considerably. Gender or duration of an AD was not related to variation in PD comorbidity.

LIMITATIONS

Blind rating of diagnoses was recorded from the papers as an indication of diagnostic validity. However, as too few studies reported it the validity of the comorbid estimates of PD was less strong.

CONCLUSIONS

The findings provided support to several of the proposed changes in the forthcoming DSM-5. Further comorbidity studies are needed in view of the substantial changes in how PDs will be diagnosed in the DSM-5.

The effectiveness of individual interpersonal psychotherapy as a treatment for major depressive disorder in adult outpatients: a systematic review

BACKGROUND

This systematic review describes a comparison between several standard treatments for major depressive disorder (MDD) in adult outpatients, with a focus on interpersonal psychotherapy (IPT).

METHODS

Systematic searches of PubMed and PsycINFO studies between January 1970 and August 2012 were performed to identify (C-)RCTs, in which MDD was a primary diagnosis in adult outpatients receiving individual IPT as a monotherapy compared to other forms of psychotherapy and/or pharmacotherapy.

RESULTS

1233 patients were included in eight eligible studies, out of which 854 completed treatment in outpatient facilities. IPT combined with nefazodone improved depressive symptoms significantly better than sole nefazodone, while undefined pharmacotherapy combined with clinical management improved symptoms better than sole IPT. IPT or imipramine hydrochloride with clinical management showed a better outcome than placebo with clinical management. Depressive symptoms were reduced more in CBASP (cognitive behavioral analysis system of psychotherapy) patients in comparison with IPT patients, while IPT reduced symptoms better than usual care and wait list condition.

CONCLUSIONS

The differences between treatment effects are very small and often they are not significant. Psychotherapeutic treatments such as IPT and CBT, and/or pharmacotherapy are recommended as first-line treatments for depressed adult outpatients, without favoring one of them, although the individual preferences of patients should be taken into consideration in choosing a treatment.

EMDR and Cognitive Behavioral Therapy in the Treatment of Panic Disorder: A Comparison

A pilot comparison was made between two treatments for panic disorder, eye movement desensitization and reprocessing (EMDR) and cognitive behavioral therapy (CBT). Treatment was provided in the private practice settings of 7 credentialed therapists, whose treatment fidelity was monitored throughout the study. Five outcome measures were administered at pretreatment, posttreatment, and 1-year follow-up. There was significant improvement for participants in both groups (N = 19) after 12 sessions of treatment. No significant differences in outcome were seen between the 2 therapies, except for lower frequency of panic attacks reported by those in the EMDR group. The current study reanalyzed the data previously reported in Faretta (2012). Further research in this area is suggested.

Sleep disturbances as a predictor of occupational injuries among public sector workers

The association between disturbed sleep and increased risk of occupational injury has been observed in several cross-sectional and case-control studies, but prospective evidence is lacking. We examined prospectively whether sleep disturbances predicted occupational injuries in a large population of Finnish public sector employees. A total of 48 598 employees working in 10 municipalities and 21 hospitals in various parts of Finland were included. Sleep disturbances were assessed with the four-item Jenkins Sleep Problems Scale. Records of sickness absence due to occupational injury during the year following the survey were obtained from employers' registers. A proportion (9076; 22%) of participants reported disturbed sleep, and 978 (2.4%) had a recorded occupational injury. After adjustment for socio-demographic characteristics, the odds ratio (OR) for occupational injury was 1.38 [95% confidence interval (CI) 1.02-1.87] times higher for men with experiences of disturbed sleep than for those without sleep disturbances, but not significant for women. Of the sub-dimensions of sleep disturbances, the OR for occupational injury was 1.69 (95% CI 1.26-2.26) for women with difficulties initiating sleep, but not significant for men. These associations remained after additional adjustment for work stress, sleep length, obesity, alcohol use and mental health. This study suggests that sleep disturbances are a significant predictor of occupational injuries even after accounting for a range of covariates.

Helpful and hindering factors for remission in dysthymia and panic disorder at 9-year follow-up: a mixed methods study

BACKGROUND

A better understanding is needed of factors behind the long-term outcome of dysthymic and panic disorders. Combining patients' perceptions of factors that help and hind remission with objective assessments of outcome may give greater insight into mechanisms for maintaining recovery.

METHODS

Twenty-three dysthymic and 15 panic disorder patients participated in a 9-year follow-up investigation of a naturalistic study with psychotherapy and antidepressants. Degree of remission was determined by reassessments with SCID-I & II interviews, self-reported symptoms and life-charting (aided by case records). Qualitative content analysis of in-depth interviews with all 38 patients was done to examine the phenomenon of enduring remission by exploring: 1) perceived helpful and hindering factors, 2) factors common to and specific for the diagnostic groups, 3) convergence between patients' subjective views on remission with objective diagnostic assessments.

RESULTS

About 50% of the patients were in full or partial remission. Subjective and objective views on degree of remission generally converged, and remission was perceived as receiving 'Tools to handle life'. Common helpful factors were self-understanding, enhanced flexibility of thinking, and antidepressant medication, as well as confidence in the therapist and social support. The perceived main obstacle was difficulty in negotiating treatments. Remitted had overcome the obstacles, whereas many non-remitted had problems expressing their needs. Patients with dysthymia and panic disorder described specific helpful relationships with the therapist: 'As a parent' versus 'As a coach', and specific central areas for change: self-acceptance and resolution of relational problems versus awareness and handling of feelings.

CONCLUSION

A general model for recovery from dysthymic and panic disorders is proposed, involving: 1) understanding self and illness mechanisms, 2) enhanced flexibility of thinking, and 3) change from avoidance coping to approach coping; and recognising that a vehicle for this change is a helpful relationship to the health care provider. The perceived needs of specific treatment ingredients suggest that it is essential to differentiate between early-onset dysthymia and secondary depressions. The perceived access problems will be further investigated.

Barriers in the help-seeking process: a multiple-case study of early-onset dysthymia in Sweden

The aim of this study was to investigate barriers to diagnosis and adequate treatment of patients with early-onset dysthymia by studying how understandings of illness by patients and providers have evolved and how treatments have been negotiated over time. A theory-testing and explorative multiple-case study design was used with developmental cognitive theory as framework. Data pertaining 10 non-remission dysthymic patients were analyzed using five sources: 1) case records, 2) interviews, 3) self-report questionnaires, 4) observations, and 5) life-charting, eliciting life events, course and treatments. The analysis comprised qualitative content analysis and a coding scheme of knowledge structures. Barriers could be explained by misunderstandings as patients mainly expressed illness in concrete, perceptually bound knowledge structures and providers focused on one aspect, instead of on the complexity of concurrent aspects. Another barrier, associated to comorbid personality disorder, was a core pattern of concealing due to fear of rejection and mistrust. Other barriers were connected to providers' attitudes and contextual factors such as access problems and lack of follow-up. A theoretical model that involves patients' understanding of illness in preoperational thinking and providers' cognitive errors can explain communication barriers. Means of shared understanding and treatment planning are suggested. Future treatment research could elucidate the impact of the core belief of rejection with associated strategy of concealing by assessing these variables as predictors and as targets for change.
