RESUMEN

BACKGROUND: Delirium is the most prevalent neuropsychiatric syndrome experienced by patients admitted to inpatient clinical units, occurring in at least 20% of medically hospitalized patients and up to 85% of those admitted to critical care units. Although current guidelines recommend the implementation of universal prevention strategies, the use of management strategies largely depends on constant surveillance and screening. This allows for the timely diagnosis and correction of its underlying causes and implementation of management strategies. OBJECTIVE: It was to adapt and analyze the Spanish adaptation of the Stanford Proxy Test for Delirium (S-PTDsv) instrument for its use among Spanish-speaking populations. The S-PTD is an instrument consisting of 13 observational items to be completed by a clinician observer, usually the patient's nurse. The completion of the questionnaire takes about 1 minute and does not require the active participation of the person evaluated, which has important clinical advantages compared to other available instruments (e.g., the Confusion Assessment Method). METHODS: The psychometric properties of the S-PTDsv were evaluated in a population of 123 patients using a quantitative, cross-sectional design. All subjects were over 18 years of age and hospitalized in various inpatient medico-surgical and intensive care unit services, either at the Barcelona Clinical Hospital (Barcelona, Spain) or the UC-Christus Health Network Clinical Hospital (Santiago, Chile, S.A.). The ultimate diagnosis of delirium was made by a member of the Psychiatry Consult Service by means of an independent neuropsychiatric evaluation based on the Fifth Edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria, published in 2013, which is the latest version of the diagnostic manual. All study tests were performed by study personnel who were blinded to each other's test results within an hour of each other. RESULTS: In the receiver operator characteristic (ROC) curve analysis, the S-PTDsv demonstrated excellent classification qualities when compared with the DSM-5 as the classification reference standard. Using a cutoff point of ≥3, the S-PTDsv had a sensitivity of 94% and a specificity of 97%. The area under the curve indicator was equal to 0.95, suggesting the S-PTDsv has an excellent overall performance in accurately identifying cases of delirium. Accordingly, the S-PTDsv's positive predictive value = 0.93, and the negative predictive value = 0.97. The internal reliability measured with Cronbach's alpha was 0.96. Confirmatory factor analysis revealed a 1-dimensional structure with high loadings (>0.72), demonstrating that all items similarly contribute to the total diagnostic dimension, suggesting adequate construct validity. This provided evidence of convergent validity. CONCLUSIONS: The performance of the S-PTDsv, as compared to a blinded neuropsychiatric assessment based on DSM-5, indicates that it is an effective instrument for the detection of delirium, in the Spanish-speaking populations. These results are comparable and consistent with previously published studies in the English language version.

RESUMEN

Evidence-based assessment (EBA) in mental health is a critical aspect of improving patient outcomes and addressing the gaps in mental health care. EBA involves the use of psychometric instruments to gather data that can inform clinical decision-making, inform policymakers, and serve as a basis for research and quality management. Despite its potential, EBA is often hindered by barriers such as workload and cost, leading to its underutilization. Regarding low- and middle-income countries (LMIC), the implementation of EBA is recognized as a key strategy to address and close the prevalent mental health treatment gap.To simplify the application of EBA including in LMIC, an international team of researchers and practitioners from Tanzania, Kosovo, Chile, and Switzerland developed the Mental Health Information Reporting Assistant (MHIRA). MHIRA is an open-source electronic health record that streamlines EBA by digitising psychometric instruments and organising patient data in a user-friendly manner. It provides immediate and convenient reports to inform clinical decision-making.The current article provides a comprehensive overview of the features and technical details of MHIRA, as well as insights from four implementation scenarios. The experience gained during the implementations as well as the user-feedback suggests that MHIRA has the potential to be successfully implemented in a variety of clinical contexts and simplify the use of EBA. However, further research is necessary to establish its potential to sustainably transform healthcare services and impact patient outcomes.In conclusion, MHIRA represents an important step in promoting the widespread adoption of EBA in mental health. It offers a promising solution to the barriers that have limited the use of EBA in the past and holds the potential to improve patient outcomes and support the ongoing efforts to address gaps in mental health care.

RESUMEN

BACKGROUND: Borderline personality disorder (BPD) is characterized by frequent and intense moment-to-moment changes in affect, behavior, identity, and interpersonal relationships, which typically result in significant and negative deterioration of the person's overall functioning and well-being. Measuring and characterizing the rapidly changing patterns of instability in BPD dysfunction as they occur in a person's daily life can be challenging. Ecological momentary assessment (EMA) is a method that can capture highly dynamic processes in psychopathology research and, thus, is well suited to study intense variability patterns across areas of dysfunction in BPD. EMA studies are characterized by frequent repeated assessments that are delivered to participants in real-life, real-time settings using handheld devices capable of registering responses to short self-report questions in daily life. Compliance in EMA research is defined as the proportion of prompts answered by the participant, considering all planned prompts sent. Low compliance with prompt schedules can compromise the relative advantages of using this method. Despite the growing EMA literature on BPD in recent years, findings regarding study design features that affect compliance with EMA protocols have not been compiled, aggregated, and estimated. OBJECTIVE: This systematic meta-analytic review aimed to investigate the relationship between study design features and participant compliance in EMA research of BPD. METHODS: A systematic review was conducted on November 12, 2021, following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and MOOSE (Meta-analyses of Observational Studies in Epidemiology) guidelines to search for articles featuring EMA studies of BPD that reported compliance rates and included sufficient data to extract relevant design features. For studies with complete data, random-effect models were used to estimate the overall compliance rate and explore its association with design features. RESULTS: In total, 28 peer-reviewed EMA studies comprising 2052 participants were included in the study. Design features (sampling strategy, average prompting frequency, number of items, response window, sampling device, financial incentive, and dropout rate) showed a large variability across studies, and many studies did not report design features. The meta-analytic synthesis was restricted to 64% (18/28) of articles and revealed a pooled compliance rate of 79% across studies. We did not find any significant relationship between design features and compliance rates. CONCLUSIONS: Our results show wide variability in the design and reporting of EMA studies assessing BPD. Compliance rates appear to be stable across varying setups, and it is likely that standard design features are not directly responsible for improving or diminishing compliance. We discuss possible nonspecific factors of study design that may have an impact on compliance. Given the promise of EMA research in BPD, we also discuss the importance of unifying standards for EMA reporting so that data stemming from this rich literature can be aggregated and interpreted jointly.

RESUMEN

Experts in personality disorders (PDs) generally prefer dimensional diagnostic systems to categorical ones, but less is known about experts' attitudes toward personality pathology diagnoses in adolescents, and little is known about public health shortfalls and advocacy needs and how these might differ geographically. To fill these gaps, the International Society for the Study of Personality Disorders surveyed 248 professionals with interests in PDs about their attitudes toward different diagnostic systems for adults and adolescents, their PD-related clinical practices, and perceived advocacy needs in their area. Results suggested that dimensional diagnostic systems are preferable to categorical and that skepticism about personality pathology in adolescents may not be warranted. The most pressing advocacy need was the increased availability of PD-related services, but many other needs were identified. Results provide a blueprint for advocacy and suggest ways that professional societies can collaborate with public health bodies to expand the reach of PD expertise and services.

RESUMEN

The Diagnostic and Statistical Manual of Mental Disorders-fifth Edition's (DSM-5) Level of Personality Functioning Scale (LPFS) was introduced as a dimensional rating of impairments in self- and interpersonal functioning, and the LPFS-Brief Form (LPFS-BF) was the first published corresponding self-report. The updated LPFS-BF 2.0 has been translated into several languages and international research supports many of the instrument's psychometric properties; however, its measurement invariance has only been evaluated across a few countries. This study expands previous studies as an introductory step in a global evaluation of the LPFS-BF 2.0s measurement invariance. Archival data (N = 5,618, 57% female) from seven countries (Canada, Chile, Denmark, Germany, Italy, United Arab Emirates, United States of America) were used for this study. Participants were recruited from both community (n = 4,677) and student (n = 941) populations. After confirming adequate model fit separately in the community and student samples, we evaluated a series of increasingly stringent model comparisons to test three aspects of measurement invariance (configural, metric, scalar) and then examined latent mean differences across countries. Full scalar invariance was supported in the community sample and partial scalar invariance was supported in the student sample. Evaluation of latent mean differences revealed multiple significant differences. Overall, the LPFS-BF 2.0 appears to assess self- and interpersonal functioning impairment similarly across the included countries. Findings are discussed through the lenses of the cultures from which participants were recruited, as well as in the context of alternative explanations. Limitations, plans for future research, and implications for both research and clinical practice are offered. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMEN

QUESTION: Most adolescents live in low- and middle-income countries (LMIC), and about 10% of them face mental problems. The mental health provision gap in low- and middle-income countries could be addressed by evidence-based practices, however costs are implementational barriers. Digitalization can improve the accessibility of these tools and constitutes a chance for LMIC to use them more easily at a low cost. We reviewed free and brief evidence-based mental health assessment tools available for digital use to assess psychopathology across different domains in youth. METHODS: For the current study, instruments from a recent review on paper-based instruments were re-used. Additionally, a systematic search was conducted to add instruments for the personality disorder domain. We searched and classified the copyright and license terms available from the internet in terms of free usage and deliverability in a digital format. In the case that this information was insufficient, we contacted the authors. RESULTS: In total, we evaluated 109 instruments. Of these instruments, 53 were free and digitally usable covering 11 mental health domains. However, retrieving information on copyright and license terms was very difficult. CONCLUSIONS: Free and digitally adaptable instruments are available, supporting the strategy of using instruments digitally to increase access. The instrument's authors support this initiative, however, the lack of copyright information and the difficulties in contacting the authors and licence holders are barriers to using this strategy in LMIC. A comprehensive, online instrument repository for clinical practice would be an appropriate next step to make the instruments more accessible and reduce implementation barriers.

RESUMEN

This commentary section is based on a comparative analysis of the five articles and case examples presented in this special issue. The place of Case Formulation in the field of psychotherapy is conceptualized as a necessary bridge between diagnostic systems and clinical practice. The common aspects of the five approaches included in the issue, as well as of the cases to which they were applied, are discussed to explore their possible cross-theoretical nature, especially in psychotherapy with more severe cases. All the clients presented in this section have experienced traumas, which manifest themselves as difficulties in their interpersonal relationships. We discuss the value of Case Formulation in the context of clinical practice and research as well as the challenges of fostering the cross-theoretical approach of this tool.

RESUMEN

Background: Population-attributable risk (PAR) may help estimate the potential contribution of adverse childhood experiences (ACEs) to serious clinical presentations of depression, characterized by suicidality, previous psychiatric admissions, and episode recurrence. Objective: To determine the PAR of ACEs for serious clinical presentations of depression (high suicide risk, previous psychiatric admissions, and recurrent depression) in outpatients with ICD-10 clinical depression. Method: Systematic chart review of 1,013 adults who were assessed and/or treated in a mental health clinic in Santiago, Chile for a major depressive episode. Data were collected on demographics and clinical characteristics of depression. Exposure to ACEs was determined with the Brief Physical and Sexual Abuse Questionnaire, assessing seven types of ACEs. Multivariable logistic regression analysis was used to assess the association between exposure to ACEs and suicidality, previous psychiatric admissions, and recurrence. Predicted probabilities were used for calculations of PAR. Results: Of the 1,001 study participants with complete data, 53.3% had recurrent depression, 13.5% had high suicide risk, and 5.0% had previous psychiatric admissions. Exposure to at least one ACE was recorded for 69.0% of the sample. Exposure to at least one ACE and specific types of ACEs (i.e. childhood sexual abuse and traumatic separation from caregiver) were associated with serious clinical presentations of depression. A dose-response relationship was observed between cumulative exposure to ACEs and the most serious clinical presentations of depression. ACEs were attributed to a significant proportion of disease: 61.6% of previous psychiatric admissions, 45.0% of high suicide risk, and 14.5% of recurrent depression. Conclusions: A substantial proportion of serious clinical presentations of depression among outpatients are associated with ACEs. Early detection of depressive episodes associated with ACEs, and tailored treatment for these patients, may potentially reduce the incidence of serious complications in this population.


Introducción: El riesgo atribuible poblacional (RAP) puede ayudar a estimar la potencial contribución de las experiencias adversas infantiles (EAIs) a las presentaciones clínicas serias de la depresión, caracterizadas por riesgo suicida, hospitalizaciones psiquiátricas previas y recurrencia de episodios.Objetivo: Determinar el RAP de las EAIs para las presentaciones clínicas serias de la depresión (alto riesgo suicida, hospitalizaciones psiquiátricas previas y depresión recurrente) en pacientes deprimidos ambulatorios.Método: Revisión sistemática de fichas clínicas de 1.013 adultos que fueron evaluados y/o tratados en una clínica de salud mental en Santiago, Chile por un episodio depresivo mayor. Se recolectaron datos demográficos y sobre características clínicas de la depresión. La exposición a EAIs se determinó con el Brief Physical and Sexual Abuse Questionnaire, evaluándose siete tipos de EAIs. Se usó análisis de regresión logística multivariada para evaluar la asociación entre exposición a EAIs y riesgo suicida, hospitalizaciones psiquiátricas previas y recurrencia. Las probabilidades predichas fueron utilizadas para los cálculos de los RAP.Resultados: De 1.001 participantes del estudio con datos completos, 53,3% tuvieron una depresión recurrente, 13,5% tuvieron alto riesgo suicida, y 5,0% tuvieron hospitalizaciones psiquiátricas previas. La exposición a al menos un EAI se registró en 69,0% de la muestra. La exposición a al menos un EAI y tipos específicos de EAIs (i.e. abuso sexual infantil y la separación traumática del cuidador), se asociaron con presentaciones clínicas serias de la depresión. Se observó una relación dosis-respuesta entre la exposición cumulativa a EAIs y las presentaciones clínicas más serias de la depresión. Las EAIs se atribuyeron una proporción significativa de la enfermedad: 61,6% de las hospitalizaciones psiquiátricas previas, 45,0% del alto riesgo suicida, y 14,5% de depresión recurrente.Conclusiones: Una proporción sustancial de presentaciones clínicas serias de la depresión en pacientes deprimidos ambulatorios se asocian con EAIs. La detección temprana de los episodios depresivos asociados con EAIs y el tratamiento a la medida para estos pacientes podrían potencialmente reducir la incidencia de complicaciones serias en esta población.

RESUMEN

Distinct sources of stress have emerged during the COVID-19 pandemic. Particularly, fear is expected to generate significant psychological burden on individuals and influence on either unsafe behavior that may hinder recovery efforts or virus-mitigating behaviors. However, little is known about the properties of measures to capture them in research and clinical settings. To resolve this gap, we evaluated the psychometric properties of a novel measure of fear of illness and viruses and tested its predictive value for future development of distress. We extracted a random sample of 450 Chilean adult participants from a large cross-sectional survey panel and invited to participate in this intensive longitudinal study for 35 days. Of these, 163 ended up enrolling in the study after the demanding nature of the measurement schedule was clearly explained to them. For this final sample, we calculated different Confirmatory Factor Analyses (CFA) to evaluate the preliminary proposed structure for the instrument. Complementarily, we conducted a content analysis of the items to qualitatively extract its latent structure, which was also subject to empirical test via CFA. Results indicated that the original structure did not fit the data well; however, the new proposed structure based on the content analysis did. Overall, the modified instrument showed good reliability through all subscales both by its internal consistency with Cronbach's alphas ranging from 0.814 to 0.913, and with test-retest correlations ranging from 0.715 to 0.804. Regarding its convergent validity, individuals who scored higher in fears tended to also score higher in depressive and posttraumatic stress symptoms at baseline. Furthermore, higher fears at baseline predicted a higher score in posttraumatic stress symptomatology 7 days later. These results provide evidence for the validity, reliability, and predictive performance of the scale. As the scale is free and multidimensional potentially not circumscribed to COVID-19, it might work as a step toward understanding the psychological impact of current and future pandemics, or further life-threatening health situations of similar characteristics. Limitations, practical implications, and future directions for research are discussed.

RESUMEN

BACKGROUND: To assess whether linear effects or threshold effects best describe the association between early adverse stress (EAS) and complex and severe depression (i.e., depression with treatment resistance, psychotic symptoms, and/or suicidal ideation), and to examine the attributable risk of complex and severe depression associated with EAS. METHODS: A cross-sectional study was conducted using deidentified clinical data (on demographics, presence of complex and severe depression, and exposure to seven types of EAS) from 1,013 adults who were seen in an outpatient mental health clinic in Santiago, Chile, for a major depressive episode. Multivariate logistic regressions were fitted to estimate odds ratios (ORs), using a bootstrap approach to compute 95% bias-corrected confidence intervals (95% BC CIs). A detailed examination of the cumulative risk score and calculations of the attributable risk was conducted. RESULTS: Exposure to at least five EASs was reported by 3.6% of the sample. In the multivariate logistic regression models, there was a marked increase in the odds of having complex and severe depression associated with exposure to at least five EASs (OR = 4.24; 95% BC CI: 1.25 to 9.09), according to a threshold effect. The attributable risk of complex and severe depression associated with exposure to at least one EAS was 36.8% (95% BC CI: 17.7 to 55.9). CONCLUSIONS: High levels of EAS distinctively contribute to complex clinical presentations of depression in adulthood. Patients with complex clinical presentations of depression and history of EAS should need a differentiated treatment approach, particularly those having high levels of EAS.

RESUMEN

BACKGROUND: Childhood Trauma Questionnaire-Short Form (CTQ-SF) is an instrument to assess child abuse and neglect Aim: to adapt and confirm the psychometric properties of the Spanish version of the CTQ-SF in Chile. MATERIAL AND METHODS: The CTQ-SF was applied to 89 clinically depressed subjects (77.5% women) who consulted at an outpatient mental health clinic. Confirmatory factor analysis (CFA), reliability (Cronbach's α) tests, and convergent validity analyses with clinical markers of complex depression were carried out. RESULTS: The Chilean version of the CTQ-SF demonstrated an acceptable fit to a five-factor model, with adequate psychometric properties. The CFA revealed that a better fit to a five-factor model would be achieved after elimination of two items from the physical neglect scale, the less reliable scale of the questionnaire. The physical abuse scale discriminated between patients with a complex depression versus non-complex depression, and all the CTQ-SF's scales discriminated between patients with high suicide risk and/or history of psychiatric admissions versus those patients without this background. CONCLUSIONS: the Chilean version of the CTQ-SF shows evidence of structural and discriminant validity, and reliability, in a clinical sample. Better alternatives to specifically assess the physical neglect construct should be developed.

RESUMEN

Depression is often complicated by concurrent personality dysfunction, which poses significant challenges for clinicians and researchers. Complicated depression is thus broadly presented as a useful clinical and scientific entity, describing clients presenting with depressive symptoms that are further complicated by personality dysfunction or personality pathology. The article introduces a collection of research-based papers addressing the clinical management of patients with complicated depression. The articles in the issue provide an up-to-date framework for understanding different forms of complicated depression and provide useful clinical information to illuminate the treatment of clients presenting with difficulties at the intersection of depression and personality dysfunction.

RESUMEN

The primary aim of this study is to improve our understanding of therapists' experience of a "difficult patient" and consider the different variables involved in this label. What makes a patient be perceived as difficult by a therapist in public health services? Results of our analysis of 10 qualitative semistructured interviews of therapists working in public health service in Chile indicated that therapists' perceptions of a "difficult patient" depend on variables that go beyond the patient's intrinsic characteristics, including patients' negative attitude toward the therapist and treating team, patients' negative effects on therapists, and a difficult treatment context (e.g., work overload, scarce resources, limited number, and frequency of sessions). We illustrate the interaction of these dimensions and focus on the impact of the treating context on therapists' experience of a "difficult patient" through the case of a therapist working with a patient with complex depression in the public health system of Chile.

RESUMEN

OBJECTIVE: Because of the importance of the therapeutic alliance across psychotherapeutic treatments, it is important to study variables that predict the development of a positive therapeutic alliance. This study investigates if different levels of gender, age, and income match between therapists and clients predict early development of the therapeutic alliance. METHOD: The sample consisted of 28 therapists and 547 adult clients receiving individual psychotherapy for depressive symptoms. There were no exclusion criteria and no control over treatment delivery. Session-to-session assessments of the therapeutic alliance were collected and a growth mixture modeling framework with a priori identified classes corresponding to different levels of therapist-client match was utilized to examine differential alliance growth trajectories. RESULTS: No differential effect of match on any level was found on initial ratings of the alliance. Across levels of attribute match, clients tend to rate the alliance positively. Regarding growth, a "youth effect" and an "affluence effect" was noted. Dyads where the therapist is younger than the client, and dyads where the therapist is from a higher income status than the client, show additional growth in the alliance beyond positive initial ratings. This is effect is not constant across sessions. CONCLUSIONS: Matching on gender, income, and age can be used for case assignment heuristic, in particular to produce additional growth in the alliance beyond initial positive ratings. Clinical and scientific consequences of the study are discussed.

RESUMEN

This study assessed the psychometric properties of a Spanish version of the Shortened Outcome Questionnaire (OQ-30.2, Lambert et al., 2004) validated with a sample of 546 patients in an outpatient mental health clinic and 100 non-clinical adults in Chile. Our results show that this measure has similar normative data to the original measure, with a cutoff score for the Chilean population set at 43.36, and the reliable change index at 14. This Spanish OQ-30.2 has good internal consistency (α = 0.90), has concurrent validity with the Depressive, Anxious, and Somatoform disorders measuring scale (Alvarado and Vera, 1991), and is sensitive to change during psychotherapy. Consistent with previous studies, factorial analyses showed that both, the one-factor solution for a general scale and the three-factor solution containing three theoretical scales yielded poor fit estimates. Overall, our results are similar to past research on the OQ-45 and the OQ-30. The short version has adequate psychometric properties, comparable to those of the OQ-45, but provides a gain in application time that could be relevant in the setting of psychotherapy research with large samples, frequent assessments over time, and/or samples that may require more assistance completing items (e.g., low-literacy). We conclude that this measure will be a valuable instrument for research and clinical practice.
