Efficacy of virtual interventions for reducing symptoms of depression in community-dwelling older adults: a systematic review.

BACKGROUND: Older adults experience symptoms of depression, leading to suffering and increased morbidity and mortality. Although we have effective depression therapies, physical distancing and other public health measures have severely limited access to in-person interventions. OBJECTIVE: To describe the efficacy of virtual interventions for reducing symptoms of depression in community-dwelling older adults. DESIGN: Systematic review. SETTING: We searched MEDLINE, EMBASE, Cochrane Libraries, PsycINFO, and gray literature from inception to July 5, 2021. PARTICIPANTS AND INTERVENTIONS: We included randomized trials (RCTs) comparing the efficacy of virtual interventions to any other virtual intervention or usual care in community-dwelling adults ≥60 years old experiencing symptoms of depression or depression as an outcome. MEASUREMENTS: The primary outcome was change in symptoms of depression measured by any depression scale. RESULTS: We screened 12,290 abstracts and 830 full text papers. We included 15 RCTs (3100 participants). Five RCTs examined persons with depression symptoms at baseline and ten examined depression as an outcome only. Included studies demonstrated feasibility of interventions such as internet or telephone cognitive behavioral therapy with some papers showing statistically significant improvement in depressive symptoms. CONCLUSIONS: There is a paucity of studies examining virtual interventions in older adults with depression. Given difficulty in accessing in-person therapies in a pandemic and poor access for people living in rural and remote regions, there is an urgent need to explore efficacy, effectiveness, and implementation of virtual therapies.

Immersion in altered experience: An investigation of the relationship between absorption and psychopathology.

Understanding alterations in perceptual experiences as a component of the basic symptom structure of psychosis may improve early detection and the identification of subtle shifts that can precede symptom onset or exacerbation. We explored the phenomenological construct of absorption and psychotic experiences in both clinical (bipolar psychosis and schizophrenia spectrum) and non-clinical participants. Participants with psychosis endorsed significantly higher absorption compared to the non-clinical group. Absorption was positively correlated with all types of hallucinations and multiple types of delusions. The analysis yielded two distinct cluster groups that demarcated a distinction along the continuum of self-disturbance: on characterized by attenuated ego boundaries and the other stable ego boundaries. The study suggests that absorption is a potentially important but under-researched component of psychosis that overlaps with, but is not identical to the more heavily theorized constructs of aberrant salience and hyperreflexivity.

The intrasubjectivity of self, voices and delusions: A phenomenological analysis.

To advance the area of phenomenology of voices and their interrelatedness to forms of delusions this study investigated the prevalence and interrelatedness of co-occurring auditory verbal hallucinations (AVHs) and delusions. Additionally we explored the characterization of distinct sub-categories/clusters of AVHs and delusions. Ninety-two participants experiencing psychosis were administered standardized clinical measures. We found a significant diagnostic difference with increased prevalence of co-occurring AVHs and delusions within the schizophrenia group compared to the bipolar with psychosis group. Regardless of diagnosis, there was a significant positive correlation between AVHs and delusions of reference, persecution, control, thought insertion, thought withdrawal and thought broadcasting. However, no significant relationship was found between AVHs and grandiose, somatic, religious, guilty or jealousy-themed delusions. Cluster analysis yielded two distinct cluster groups. Cluster One: Voices and Thought Delusions, and Cluster Two: Voices and Thematic Delusions. Cluster One participants showed elevated disorganized, cognitive and depressive symptoms, but not negative symptoms or excitement. This study underscores the need for expanded clinical and phenomenological research into the intersection of AVHs and delusions, including work that seeks to deconstruct conventional divisions between ostensible symptoms of perception' (hallucinations) and belief' (delusions).

Listening to Schneiderian Voices: A Novel Phenomenological Analysis.

BACKGROUND/AIMS: This paper reports on analyses designed to elucidate phenomenological characteristics, content and experience specifically targeting participants with Schneiderian voices conversing/commenting (VC) while exploring differences in clinical presentation and quality of life compared to those with voices not conversing (VNC). METHODS: This mixed-method investigation of Schneiderian voices included standardized clinical metrics and exploratory phenomenological interviews designed to elicit in-depth information about the characteristics, content, meaning, and personification of auditory verbal hallucinations. RESULTS: The subjective experience shows a striking pattern of VC, as they are experienced as internal at initial onset and during the longer-term course of illness when compared to VNC. Participants in the VC group were more likely to attribute the origin of their voices to an external source such as God, telepathic communication, or mediumistic sources. VC and VNC were described as characterological entities that were distinct from self (I/we vs. you). We also found an association between VC and the positive, cognitive, and depression symptom profile. However, we did not find a significant group difference in overall quality of life. CONCLUSIONS: The clinical portrait of VC is complex, multisensory, and distinct, and suggests a need for further research into the biopsychosocial interface between subjective experience, socioenvironmental constraints, individual psychology, and the biological architecture of intersecting symptoms.

Diagnostic and prognostic significance of Schneiderian first-rank symptoms: a 20-year longitudinal study of schizophrenia and bipolar disorder.

OBJECTIVE: This research addresses the following questions: what is the prevalence and severity of first-rank symptoms (FRS) during an extended period of time in patients with schizophrenia and bipolar disorder with psychosis? Are the specific FRS listed in Diagnostic and Statistical Manual of Mental Disorders DSM, Third Edition, Revised/Fourth Edition Criterion A for schizophrenia diagnosis (a voice keeping a running commentary or voices conversing) more prevalent and severe in patients with schizophrenia than bipolar disorder with psychosis? Lastly, do FRS at index hospitalization in patients with schizophrenia predict the absence of later recovery? METHODS: This research follows a sample of patients with psychotic disorders who were evaluated at index hospitalization and then prospectively followed-up at 6 evaluations during next 20 years (n = 86). All patients were evaluated as part of a prospective research study designed to measure multiple factors of phenomenology, severity of illness, course of illness, prognosis, and global outcome. RESULTS: First-rank symptoms are not exclusive to schizophrenia; they also occur in some bipolar patients. However, they are more frequent and more severe in patients with schizophrenia than bipolar disorder. Schizophrenia patients with FRS during the acute phase are more likely to have poorer long-term outcome than schizophrenia patients who do not have FRS during the acute phase. CONCLUSIONS: Our results indicate FRS at the acute phase are not a clinicopathologic correlate specific to schizophrenia. However, the presence and severity of any FRS and specifically of the 2 FRS associated with Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised/Fourth Edition Criterion A are more prevalent and more severe in patients with schizophrenia than patients with bipolar disorder.

Neurocognition in schizophrenia: a 20-year multi-follow-up of the course of processing speed and stored knowledge.

Individuals with schizophrenia have relative deficits in cognition, although little is known regarding the course of such deficits across the life span and at various stages of the illness. Furthermore, the relationship between psychosis and cognition has not been adequately explored to this point. Prospective, longitudinal, multi-assessment studies of the same patients across time are rare in the field and provide a unique opportunity to examine long-term changes in cognition among individuals with schizophrenia. As part of The Chicago Follow-up Study, we prospectively assessed 244 psychiatric inpatients, including individuals with schizophrenia, other psychotic disorders, and nonpsychotic depression. Assessments were conducted 7 times (once at index hospitalization and then 6 times subsequently for the next 20 years) to provide longitudinal data about cognition and symptoms, with a focus on 2 aspects of cognition: processing speed and the ability to access general knowledge. The Digit Symbol-Coding and Information subtests from the Wechsler Adult Intelligence scale were used to measure the 2 cognitive domains at each assessment. At all 7 assessments, individuals with schizophrenia performed more poorly than the other diagnostic groups on the 2 cognitive measures. However, after the acute phase (index hospitalization), individuals with schizophrenia demonstrated significant improvements in cognition and did not show evidence of cognitive decline over the remaining 6 assessments spanning 20 years. Our data support the presence of relative cognitive impairment in schizophrenia, as well as a pattern of stability in some cognitive areas after the acute phase. In addition, we find evidence for an association between relative cognitive impairment and psychosis.

Periods of recovery in deficit syndrome schizophrenia: a 20-year multi-follow-up longitudinal study.

Periods of recovery were examined in patients with and without deficit syndrome schizophrenia. Fifty-six patients with schizophrenia were studied, 39 of whom were divided into deficit and nondeficit syndrome schizophrenia subtypes using a proxy method. We also studied 39 nonpsychotic depressive comparison patients. Patients were evaluated as part of the Chicago Follow-up Study, which prospectively examined patients at regular intervals over a 20-year period. Using standardized instruments, patients were evaluated for the deficit syndrome, global recovery, rehospitalization, social dysfunction, occupational disability, and symptom presentation. Recovery was examined at 6 time points measured at 2-, 4.5-, 7.5-, 10-, 15-, and 20-year postindex hospitalization. Cumulatively, over the 20-year period, 13% of patients classified as meeting criteria for the deficit syndrome showed 1 or more 1-year periods of global recovery, in comparison to 63% of nondeficit schizophrenia patients and 77% of depressed patient controls. Results indicate that the deficit syndrome represents a persistently impaired subsample of schizophrenia patients, with continuous social, occupational, and symptom impairment. In contrast, nondeficit syndrome schizophrenia patients showed at least some periods of remission or recovery, with the likelihood of these periods increasing as they became older. Findings provide further support for the validity of the deficit syndrome concept and suggest that deficit status is characterized by a more persistently impaired course of illness and particularly poor long-term prognosis.

Sex differences in schizophrenia and other psychotic disorders: a 20-year longitudinal study of psychosis and recovery.

This longitudinal study was designed to provide data on sex differences in the course of schizophrenia and other psychotic disorders. Ninety-seven participants (43 women and 54 men) were assessed during index hospitalization when they were in the acute phase of illness and then reassessed prospectively at 6 consecutive follow-ups over a 20-year period. Patients were evaluated by a series of standardized measures on many aspects of illness including the presence of psychosis, global outcome, and rate of recovery. When women were compared to men in this sample, the data demonstrated a lower percentage of psychotic activity for women over the course of illness (significant at the 7.5- and 20-year follow-ups), and a significant improvement in psychotic activity over 20 years for women (P < .05), but not for men. In addition, women showed significantly better global functioning (P < .05) at 3 of the 6 follow-ups (the 2-, 7.5-, and 10-year follow-ups). Significantly higher percentages (P < .05) of women were in recovery at 2 of the 6 follow-up years (the 2- and 10-year follow-ups). Cumulatively, 61% of the women with schizophrenia showed a period of recovery at some point during the 20-year period compared to 41% of the men. The sex difference patterns were similar for patients with schizophrenia and for those with other types of psychotic disorders. Sex differences in this sample were specifically not attributable to differences in age of onset or premorbid developmental achievements.

Subjective evaluations of research participation by persons with mental illness.

The present study focuses on the subjective experience of psychiatric patients who participate in psychobiological research, based on patients' self-reported evaluations of the experience. We studied 313 persons with mental illness admitted to an inpatient research unit. Each participant was administered the Patient Satisfaction Questionnaire, a structured self-report questionnaire designed to assess satisfaction with research participation and clinical care. Individuals who completed the research protocol were significantly more satisfied globally and more likely to express that treatment had been effective. Factors contributing to willingness to participate in future research included favorable perceptions of: (a) psychoeducation, (b) safety, and (c) comfort level with research procedures. Research participants were willing to participate in future research regardless of their perception of medication efficacy. This study emphasizes the importance of understanding the opinions of persons with mental illness who participate in research. Overall, the data suggest that persons with mental illness find psychiatric research to be beneficial. Although therapeutic misconception cannot be ruled out given the methodology used, at the very least the data indicate no sign that subjects found research participation to be harmful. Further studies should explore the source of this perception and attempt to separate the effect of "therapeutic misconception" from possible real benefit of protocol-driven assessment and treatment in a reputable clinical environment.

Sex differences in outcome and recovery for schizophrenia and other psychotic and nonpsychotic disorders.

OBJECTIVE: It is generally believed by the field of psychiatry that women with schizophrenia have better outcomes and higher rates of recovery than their male counterparts, because many studies on the topic support this finding. Fewer data are available to assess potential sex differences among individuals with other psychotic disorders. This study used longitudinal data on sex differences previously unavailable to the field to examine long-term global outcome, potential recovery, course of illness, and rehospitalization for schizophrenia, other psychotic disorders, and nonpsychotic disorders. METHODS: A total of 239 young psychiatric patients (mean age of 23.4 years) were assessed prospectively at the index hospitalization and then followed over 15 years at five follow-up points (at a mean of two, 4.5, 7.5, ten, and 15 years). The sample consisted of 69 patients with schizophrenia, 56 with other psychotic diagnoses, and 114 with nonpsychotic psychiatric disorders. RESULTS: Sex differences in outcome were found for both patients with schizophrenia and those with other psychotic disorders, with women consistently showing better functioning over time, more frequent periods of good functioning and periods of recovery, less likelihood of uniformly poor outcome, and fewer and shorter rehospitalizations. Unlike both groups of patients who were psychotic, the patients with nonpsychotic disorders showed no significant sex differences in outcome. CONCLUSIONS: Both longitudinally and at each individual follow-up point, the data suggest that women with schizophrenia and with other types of psychotic disorders generally show better outcome than men with similar diagnoses. The sex differences in outcome for patients with schizophrenia were consistent over time. However, these sex differences were only moderate in size compared with the much larger difference in outcome between the diagnostic groups. The longitudinal data add a new dimension to previous research and suggest that sex differences in outcome are not specific to patients with schizophrenia but rather occur among patients with psychotic disorders in general.

Do patients with schizophrenia ever show periods of recovery? A 15-year multi-follow-up study.

Contrary to older views, with modern treatment some or many patients with schizophrenia may show intervals of recovery. The current 15-year prospectively designed follow-up research comparing schizophrenia patients with other types of psychotic and nonpsychotic patients studied how many schizophrenia patients ever show intervals of recovery. Two hundred seventy-four early young psychiatric patients from the Chicago Followup Study, including 64 schizophrenia patients, 12 schizophreniform patients, 81 other psychotic patients, and 117 nonpsychotic patients, were assessed as inpatients and then reassessed 5 times over 15 years. Patients were evaluated for recovery for 1 or more years using an operational definition of recovery. Cumulatively, over the 15-year period slightly over 40% of patients with schizophrenia showed 1 or more periods of recovery. However, schizophrenia is still a relatively poor outcome disorder, showing poorer courses than other types of psychotic and nonpsychotic disorders (p < .001). Most schizophrenia patients did not show the severe social isolation often described prior to the modern treatment era. Schizophreniform patients tended to show more favorable outcomes than schizophrenia patients. Over 50% of the schizophrenia patients did not have a disorder that was chronic and continuous. Rather, their disorder was episodic, although for many more vulnerable and less resilient schizophrenia patients the episodes were more frequent and severe, with slower recovery.

Can sex offenders who minimize on the MMPI conceal psychopathology on the Rorschach?

Rorschach sensitivity to minimization is important in forensic evaluations of sex offenders because these individuals frequently deny psychological problems. To study Rorschach minimization, we divided alleged sex offenders according to whether they minimized on the MMPI (Hathaway & McKinley, 1943) or MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) and compared their Rorschachs on indexes of distress, faulty judgment, interpersonal dysfunction, and cognitive distortions. We predicted there would be no differences between MMPI minimizers and nonminimizers on these indexes and that sex offenders of both groups would show greater psychopathology than normative adult samples. Results indicate that mini- mizers produce normal MMPI clinical profiles but still show evidence of psychopathology on the Rorschach. As predicted, sex offenders showed more Rorschach psychopathology than normative samples. Sex offenders' protocols that contained sexual content also showed perceptual distortions. These findings indicate that the Rorschach is resilient to attempts at faking good and may therefore provide valuable information in forensic settings where intentional distortion is common.
