This interview was designed to assess the lifetime presence of symptoms and other clinical features considered to comprise the panic-agoraphobic spectrum. The interview has 114 items grouped into nine domains. A total of 422 subjects, from 11 centres located throughout Italy, participated in this study. Data were collected from three groups of subjects: psychiatric patients meeting DSM-IV criteria for panic disorder (n = 141), cardiovascular patients (n = 140), including 29 with post-myocardial infarction, and university students (n = 141). The inter-rater reliability and the internal consistency of the SCI-PAS measures were assessed using the intra-class correlation coefficient and the Kuder-Richardson coefficient, respectively. Discriminant validity was assessed by comparing results in patients with panic disorder to those in the other groups. The interview required an average of 25 (±5) minutes to administer. Patients and clinicians found the scale to be highly useful, providing information not previously obtained. Internal consistency was good (>0.70) for six out of nine SCI-PAS domains. The inter-rater reliability was excellent (>0.70) for all the domains except for 'other phobias' (0.467). Patients with panic disorder scored significantly higher on each domain, and on the overall panic spectrum, than did the control subjects. In conclusion, the SCI-PAS is a useful clinical interview, which can be administered in a reasonable period of time. This assessment further demonstrates good internal consistency, discriminant validity, and inter-rater reliability.

Related somatic and psychiatric symptoms include muscle tension, sleep disturbance, and fatigue. Individuals with GAD have poorer quality of life, 3 with impairments in role functioning (encompassing social, occupational, and family functioning) on par with those observed in major depressive disorder and other common medical problems such as arthritis and diabetes. 4,5 The prevalence of GAD is as high as 7.3% in community-dwelling older adults 6 and higher in primary care 7 where they are most likely to present for treatment. 8 In older adults, GAD is associated with poorer quality of life, 9-11 increased health care utilization, 11 and cognitive impairment. 12,13 Addition

The purpose of this study was to determine whether comorbid GAD or PD was associated with poorer long-term outcomes of late-life MDD, in terms of symptoms, functional disability, and cognitive status. Seventy-nine older subjects with major depressive disorder who had responded to initial treatment in clinical trials were followed at yearly intervals for up to four years with assessment of their symptoms, cognitive status, and functional disability. For this analysis, subjects were divided into two groups, anxious and non-anxious, based on presence (n = 37) or absence (n = 42) of a lifetime diagnosis of GAD and/or PD. The anxious group showed a greater decline in memory, but not in other cognitive measures or measures of functional status. Depression recurrence was similar in the anxious and non-anxious groups. Among those in the anxious group, a later age of onset (> 55) of the anxiety disorder was associated with worse overall cognition at baseline, but a similar rate of decline in cognition over time, compared with early-onset anxiety disorder. We found evidence that comorbid GAD or PD is associated with a greater decline in memory in late-life MDD. The data also suggest that anxiety disorders with an onset later in life may be associated with cognitive impairment, although further study is needed to confirm this finding.

In the DSM-IV-TR, in fact, this condition was typically considered to begin in childhood. Clinical data report prevalence rates from 20 to 40%, showing high comorbidity rates with most mental disorders. Epidemiological data highlight that in fact one third of childhood cases persist into adulthood, while the majority of adult cases reports its first onset in adulthood. In all cases, Separation Anxiety Disorder is associated with a severe impact on the overall functioning. Most relevant research in the field is discussed highlighting the need of a paradigm shift in which clinicians are alerted to identify and treat this condition in all age upon the recent DSM-5 reformulation will be highlighted.

It is probably the greatest sorrow that can occur in an individual life. Grief is a normal, healthy response to loss, evolving through stages in the process of mourning. In some cases, bereavement may lead to the outburst of manic episode: despite literature data being scarce, reports have explored this important clinical entity, variously called as "funeral mania" or "bereavement mania". We systematically reviewed the literature exploring the possible relationships between bereavement and the onset of a manic episode, both first or recurrent pre-existing episode, besides describing a case report on a manic episode in the aftermath of a loss event, with an accurate evaluation of prior mild mood spectrum instability, supporting the role of loss-events as potential risk factor for bipolar illness progression. This article tries summarizing existing evidence on the debate whether clinicians should consider mania as a possible bereavement reaction.

Most bereaved individuals experience a period of acute grief that diminishes in intensity as they adapt to the changes brought about by their loss. Over the past four decades, a growing body of research has focused on a form of prolonged grief that is painful and impairing. There is a substantial and growing evidence base that supports the validity and significance of a grief-related disorder, including the clinical value of being able to diagnose it and provide effective targeted treatment. ICD-11 will include a new diagnosis of prolonged grief disorder (PGD). DSM-5 called this condition persistent complex bereavement disorder (PCBD) and included it in Section III, signaling agreement that a diagnosis is warranted while further research is needed to determine the optimal criteria. Given the remaining uncertainties, reading this literature can be confusing. There is inconsistency in naming the condition (including complicated grief as well as PGD and PCBD) and lack of uniformity in identifying it, with respect to the optimal threshold and timeframe for distinguishing it from normal grief. As an introductory commentary for this Depression and Anxiety special edition on this form of grief, the authors discuss the history, commonalities, and key areas of variability in identifying this condition. We review the state of diagnostic criteria for DSM-5 and the current ICD-11 diagnostic guideline, highlighting the clinical relevance of making this diagnosis.

Due to younger age and bereavement by sudden and violent deaths, military widows may be vulnerable to poor outcomes. No systematic research has examined these effects. Method: Using outpatient medical records from wives of active-duty military service members (SMs), we compared the prevalence of mental health conditions and mental healthcare visits among case widows (n = 1,375) to matched (on age, baseline healthcare utilization, SM deployment, and rank) nonbereaved control military wives (n = 1,375), from 1 year prior (Yr−1) to 2 years following (Yr+1 and Yr+2) SM death. Prevalence risk ratios and confidence intervals were compared to determine prevalence rates of mental health conditions and outpatient mental healthcare visits over time. Results: The prevalence of any mental health condition, as well as a distinct loss-and stress-related mental health conditions, significantly increased from Yr−1 to Yr+1 and Yr+2 for cases as did mental healthcare utilization. Widows with persistent disorders (from Yr+1 to Yr+2) exhibited more mental conditions and mental healthcare utilization than widows whose conditions remitted. Conclusion: Bereavement among military widows was associated with a two-to fivefold increase in the prevalence of depression, posttraumatic stress disorder, and adjustment disorder postdeath, as well as an increase in mental healthcare utilization. An increase in the prevalence of loss-and stress-related conditions beyond 1 year after death indicates persistent loss-related morbidity. Findings indicate the need for access to healthcare services that can properly identify and treat these loss-related conditions.

As four diagnostic criteria sets for a grief disorder have been proposed, their similarities and differences need to be elucidated.MethodsParticipants were family members bereaved by US military service death (N= 1732). We conducted analyses to assess the accuracy of each criteria set in identifying threshold cases (participants who endorsed baseline Inventory of Complicated Grief ⩾30 and Work and Social Adjustment Scale ⩾20) and excluding those below this threshold. We also calculated agreement among criteria sets by varying numbers of required associated symptoms.ResultsAll four criteria sets accurately excluded participants below our identified clinical threshold (i.e. correctly excluding 86–96% of those subthreshold), but they varied in identification of threshold cases (i.e. correctly identifying 47–82%). When th...

In order to identify their grief-related health care needs, a first step is to identify the characteristics of persistent and elevated grief in a military family sample. The present study identified military family members (n = 232) bereaved more than six months who endorsed an elevated level of grief. A confirmatory factor analysis and test of measurement invariance of factor structure were used to compare the factor structure of their Inventory of Complicated Grief (ICG) responses to that of a bereaved non-military-related clinical research sample with similar grief levels. Results confirmed an equivalent five-factor structure of the ICG in both the military family sample and the clinical research sample. The similarity in factor structure was present despite differences in demographic characteristics and bereavement experiences between samples. Thus, the ICG reliably measures per...

Performance of criteria sets for prolonged grief disorder and complicated grief were similarly assessed. Participants were family members of U.S. military service members who died of any cause since September 11, 2001 (N=1,732). Putative clinical and nonclinical samples were derived from this community sample using cutoff scores from the Inventory of Complicated Grief and the Work and Social Adjustment Scale. Items from a self-report grief measure (Complicated Grief Questionnaire) were matched to DSM-5 persistent complex bereavement disorder, prolonged grief disorder, and complicated grief criteria. Endorsed items were used to identify cases. Criteria sets varied in their ability to identify clinical cases. DSM-5 persistent complex bereavement disorder criteria id...

Anxiety sensitivity has recently emerged as a risk factor of suicide. This study aimed to investigate a possible association between anxiety sensitivity and a wish to die in individuals with complicated grief. Participants were evaluated for participation in a treatment study and completed an ancillary questionnaire-based study. Participants were 51 bereaved adults evaluated (age: mean, 54 [SD, 13.6] years; 78% [n = 40] women). Logistic regression was used to examine the relationship between anxiety sensitivity and a wish to die. Overall, anxiety sensitivity was associated with a wish to die at the level of a medium effect size, although it did not reach statistical significance. The anxiety sensitivity social concerns subscale was significantly associated with a wish to die. These findings add to a growing literature implicating anxiety sensitivity in reporting a wish to die.

We sought to determine whether measures of spectrum psychopathology are useful in deciding which patients with unipolar depression should receive pharmacotherapy versus depression-specific psychotherapy.MethodA total of 318 adult out-patients with major depression were randomly assigned to escitalopram pharmacotherapy or interpersonal psychotherapy (IPT) at academic medical centers at Pittsburgh, Pennsylvania and Pisa, Italy. Our main focus was on predictors and moderators of time to remission on monotherapy at 12 weeks.ResultsParticipants with higher scores on the need for medical reassurance factor of the Panic–Agoraphobic Spectrum Self-Report (PAS-SR) had more rapid remission with IPT and those with lower scores on the psychomotor activation...

Methods-The present study examined rates of bereavement and threshold CG symptoms (defined as a score ≥ 25 on the Inventory of Complicated Grief scale) in 111 outpatients with major depressive disorder (MDD) and 142 healthy controls participating in a study of stress and depression. Clinical and demographic characteristics were also compared for bereaved individuals with CG (MDD + CG) to those without (MDD-CG). Participants completed structured diagnostic interviews as well as measures of CG, depression, anxiety, exposure to traumatic events, and perceived social support. Results-Lifetime history of a significant loss did not differ for the MDD and control groups (79.3% vs. 76.1%), but bereaved participants with MDD had higher rates of threshold CG (25.0% vs. 2.8%). Amongst those with MDD, CG was associated with a higher prevalence of lifetime alcohol dependence, greater exposure to traumatic events, and lower perceived social support. Depressed women, but not men, with CG also had higher rates of panic disorder, social anxiety disorder, and posttraumatic stress disorder.

This investigation sought to provide clinically meaningful anchor points for the PDSS both in terms of clinical severity as measured by the Clinical Global Impression–Severity Scale (CGI-S) and to extend its clinical meaningfulness by examining its association with quality of life. A total of 63 individuals with a primary diagnosis of panic disorder were assessed on completion of a 6- or 8-week psychotherapy or pharmacotherapy trial for the treatment of panic disorder. As expected, the PDSS was correlated with both the CGI-S and quality of life. These results provide further support for the validity and clinical utility of the PDSS and provide simple anchors to help guide the potential use of the PDSS scale to measure treatment progress in clinical practice.

The goals of this preliminary study were to explore whether the dream content of 77 adults with complicated grief (CG) differed from that of a normative sample, and to explore whether CG patients who dream of the deceased differ from CG patients who do not dream of the deceased on measures of daytime emotional distress. CG dreams were characterized by more family and familiar characters including the deceased (in women), and fewer social interactions and emotions compared to norms. Increased representations of familiar characters in CG dreams may reflect attempts to reorganize relational cognitive schemas to compensate for the loss.
