RESUMO

BACKGROUND: Maternal antenatal depression affects 21-28% of expectants globally and negatively impacts both maternal and child health in the short and long term. OBJECTIVE: To compare the psychometric properties and clinical utility of the Edinburgh Postnatal Depression Scale (EPDS) and the Patient Health Questionnaire (PHQ-9) in pregnant individuals. METHODS: In this cross-sectional study, 953 third-trimester pregnant Italian individuals completed both the EPDS and the PHQ-9. RESULTS: Both scales demonstrated good internal consistency (EPDS ω=0.83, PHQ-9 ω=0.80) and a moderate correlation between their scores (r=0.59). Concordance at recommended cut-off points (≥14 for both) was moderate (k=0.55). Factor analyses indicated a bifactor solution for the EPDS (dimensions: "depression" and "anxiety") and for the PHQ-9 (dimensions: "depression", "pregnancy symptoms", "somatic"). Benchmarks for clinical change were also established. CONCLUSIONS: The EPDS and PHQ-9 capture distinct aspects of perinatal depressive symptomatology. Clinically, these findings recommend using both scales in obstetric and gynaecologic settings to minimize false positives and negatives.

RESUMO

Background: Psychotherapists need effective tools to monitor changes in the patient's affective perception of the therapist and the therapeutic relationship during sessions to tailor therapeutic interventions and improve treatment outcomes. This study aims to evaluate the factor structure, reliability, and validity of the in-Session Patient Affective Reactions Questionnaire (SPARQ), a concise self-report measure designed for practical application in real-world psychotherapy settings. Methods: Validation data was gathered from (N = 700) adult patients in individual psychotherapy. These patients completed the SPARQ in conjunction with additional measures capturing sociodemographic details, characteristics of therapeutic interventions, individual personality traits, mental health symptom severity, elements of the therapeutic relationship, and session outcomes. This comprehensive approach was employed to assess the construct and criterion-related validity of the SPARQ. Results: The SPARQ has a two-factor structure: Positive Affect (k = 4, ω total = .87) and Negative Affect (k = 4, ω total = .75). Bifactor confirmatory factor analysis (CFA) yielded the following fit indices: X2[df] = 2.53, CFI = .99; TLI = .98; RMSEA = .05; and SRMR = .02. Multi-group CFAs demonstrated measurement invariance (i) across patients who attended psychotherapy sessions in person versus in remote mode, and (ii) across patients with and without psychiatric diagnoses confirmed metric invariance. Furthermore, the SPARQ showed meaningful correlations with concurrently administered measures. Discussion: The SPARQ proves to be a valuable instrument in clinical, training, and research contexts, adept at capturing patients' session-level affective responses towards their therapist and perceptions of the therapeutic alliance. Comprehensive descriptive statistics and a range of score precision indices have been reported, intended to serve as benchmarks for future research.

RESUMO

Recognizing the need for a concise self-report measure of mentalizing capacity, we developed a 12-item iteration of the well-established Mentalization Scale (MentS). Using college student and community samples of Serbian adults (N = 566), we performed a precise selection of items and then examined the psychometric attributes of the shortened scale (MentS-12). The new scale maintains the original three-dimensional structure: self-related mentalization, other-related mentalization, and motivation to mentalize. MentS-12 proves to be both reliable and structurally consistent. To improve its utility in therapeutic contexts, we determined clinical change thresholds for both the complete and abbreviated forms. We hope that its feasibility stimulates the integration of the MentS-12 in longitudinal research projects and real-world clinical settings.

RESUMO

BACKGROUND: The quality of the therapeutic relationship is pivotal in determining psychotherapy outcomes. However, facilitating patients' self-awareness, reflection on, and sharing of their affective responses toward their therapist remains underexplored as a potential tool for enhancing this relationship and subsequent treatment outcomes. OBJECTIVE: The primary objective of this study is to examine whether and how the patients' regular self-monitoring and self-reflection (fostered by the systematic compilation of a brief postsession battery) on their affective reactions toward the psychotherapist impact the quality of the therapeutic relationship and treatment outcomes in individual psychotherapy. Secondary objectives are to (1) explore whether and how the characteristics of the patient, the therapist, and the process moderate the effect of regular self-monitoring on the therapeutic relationship and outcomes; (2) examine the relationships between the affective response of the patient, the alliance, and the result of the therapy session outcome; and (3) explore how the affective responses of the patient unfold or change throughout the course of the therapy. METHODS: We conducted a 1:1 randomized controlled trial of adults in individual psychotherapy versus individual psychotherapy plus self-monitoring. Participants will be enrolled through the web-based recruitment platforms "ResearchMatch" and "Research for Me," and data will be collected through web-based surveys. Participants in the control group will receive only their regular individual psychotherapy (treatment as usual) and will not complete postsession questionnaires. Participants in the intervention group will continue their regular individual psychotherapy sessions and complete the "in-Session Patient Affective Reactions Questionnaire" and the "Rift In-Session Questionnaire" following each therapy session in the 10 weeks of the trial. Additionally, after completion of the postsession battery, they will receive general written feedback encouraging them to discuss their feelings and reflections with their therapist. Participants in both groups will complete a comprehensive psychological assessment at baseline, midtrial (week 5), and end-of-trial (week 10). The primary outcome measure of the trial is the "Clinical Outcomes in Routine Evaluation-Outcome Measure," while the secondary outcomes are the "Real Relationship Inventory-Client-Short Form," the "Working Alliance Inventory-Short Revised," and the number of scheduled therapy sessions that the patient has missed or canceled. RESULTS: The trial was approved by the institutional review board of the University of North Carolina at Chapel Hill. Recruitment started in September 2023. A total of 475 individuals completed the baseline assessment. Data collection was completed in February 2024. The results are expected to be published in the autumn of 2024. CONCLUSIONS: This study could reveal key information on how regular self-monitoring and introspection can influence both the therapeutic relationship and treatment outcomes. Findings have the potential to shape interventions, enhance the efficacy of psychotherapeutic sessions, and possibly offer a cost-effective strategy for improving patients' well-being.

RESUMO

OBJECTIVE: To develop and validate a very brief version of the 24-item Real Relationship Inventory-Client (RRI-C) form. METHOD: Two independent samples of individual psychotherapy patients (Nsample1 = 700, Nsample2 = 434) completed the RRI-C along with other measures. Psychometric scale shortening involved exploratory factor analysis, item response theory analysis, confirmatory factor analysis (CFA), and multigroup CFA. Reliability and convergent and discriminant validity of the scale and subscales were also assessed. RESULTS: The 8-item RRI-C (RRI-C-SF) preserves the two-factor structure: Genuineness (k = 4, α = .86) and Realism (k = 4, α = .87), which were correlated at r = .74. CFA provided the following fit indices for the bifactor model: X2/df = 2.16, CFI = .99, TLI = .96, RMSEA = .07, and SRMR = .03. Multigroup CFA showed that the RRI-C-SF was invariant across in-person and remote session formats. The RRI-C-SF demonstrated high reliability (α = .91); high correlation with the full-length scale (r = .96); and excellent convergent and discriminant validity with measures of other elements of the therapeutic relationship, personality characteristics, current mental health state, and demographic-clinical variables. Clinical change benchmarks were calculated to serve as valuable tools for both research and clinical practice. CONCLUSION: The RRI-C-SF is a reliable measure that can be used for both research and clinical purposes. It enables a nuanced assessment of the genuineness and the realism dimensions of the real relationship.

RESUMO

The present study reports on the development and validation of the clinician affective response (CARE) scale. The CARE scale was designed as a self-report measure of therapists' patterns of thoughts, feelings, and behaviors toward the patient during an individual psychotherapy session. An initial pool of 116 items was generated, and its quality was evaluated by subject matter experts. Validation data were gathered from licensed psychotherapists (n=554). We used exploratory factor analysis and item response theory-graded response modeling to select items, confirmatory factor analysis to test how well the factor structure fit the data, and k-fold cross-validation to ascertain the robustness of the model. Criterion validity was evaluated by correlating the scores of the scale with the characteristics of therapists, patients, and treatment. The selected model consists of 15 items and a 3-factor structure, which showed excellent model fit, good internal consistency, and evidence of criterion validity. The CARE scale, short and quick to complete, enables therapists to reflect on and recognize their inner experiences and quantify these experiences in ways conducive to statistical analysis and research. Furthermore, the monitoring of these affective reactions toward their patients can guide therapeutic interventions and inform clinical supervisors.

RESUMO

Ill children/adolescents who suffer from severe organic diseases have to cope with their inner experiences, therapies, and the global burden of the disease. Although sometimes depression, anger, and death anxiety are openly encountered in medical settings, other times they can be partially hidden by a reactive and defensive path. In these scenarios, psychoanalysis is challenged to contribute the best comprehension of the intimate communication, maybe hidden, and the needs of the ill patients to express themselves. The best way a child can talk about himself is through spontaneous creativity. The adult's task is to facilitate the creation of an empty space and to recognize the child's mode of communication. There may be intense emotional reactions that the adult has to tolerate to not move the patient towards an over-adaptation. These over-adaptations entail the child being forced to feel good or have fun, thereby causing them to escape from their inner experience. The loss of the child's reality forms an additional burden to the child. The most valid indicator of this attitude is the ability to not take counterphobic attitudes but to allow the depression to be shared in a contact space between the child's true self and the perceived environment.

RESUMO

This article discusses the development and preliminary validation of a self-report inventory of the patient's perception of, and affective reaction to, their therapist during a psychotherapy session. First, we wrote a pool of 131 items, reviewed them based on subject matter experts' review, and then collected validation data from a clinical sample of adult patients in individual therapy (N = 701). We used exploratory factor analysis and item response theory graded response models to select items, confirmatory factor analysis (CFA) to test the factor structure, and k-fold cross-validation to verify model robustness. Multi-group CFA examined measurement invariance across patients with different diagnoses (unipolar depression, bipolar disorder, and neither of these). Three factors produced short scales retaining the strongest items. The in-Session Patient Affective Reactions Questionnaire (SPARQ) has a two-factor structure, yielding a four-item Negative affect scale and a four-item Positive affect scale. The Relationship In-Session Questionnaire (RISQ) is composed of four items from the third factor with dichotomized responses. Both scales showed excellent psychometric properties and evidence of metric invariance across the three diagnostic groups: unipolar depression, bipolar disorder, and neither of these. The SPARQ and the RISQ scale can be used in clinical or research settings, with particular value for capturing the patient's perspectives about their therapist and session-level emotional processes.

RESUMO

Experiencing erotic feelings towards a patient is a fairly common occurrence, not pathological per se, during phases of psychotherapy. This study aims to analyze associations between, on the one hand, the presence in therapists of romantic attraction (RA), sexual attraction (SA), or flirting behavior (FB) toward patients and, on the other hand, a series of characteristics of therapist, patient, and treatment. Between April and June 2022, 547 psychotherapists completed an online survey investigating their affective and behavioral responses toward their most recently treated patient. Compared to female therapists, males showed significantly higher prevalence of SA alone (p < .001) or in combination with RA (p < .01), FB (p < .01), or both (p < .05). Multivariate adjusted regression models showed that RA was associated with patient age ≤40 years (OR:39.49 for age 18-29; OR:28.44 for age 30-39), male sex (OR:10.40), and diagnosis of mood disorder (OR:14.08). Furthermore, RA was associated with intense countertransference feelings of tenderness towards the patient (OR:79.77) and hostility towards significant figures in their life (OR: 77.93). SA was associated with the therapist's male sex/gender (OR: 16.14), psychoanalytic orientation (OR:13.34), post-license experience ≤20 years (OR:6.12 for 1-9 years; OR:6.08 for 10-19 years). Lastly, FB was associated with the therapist's male sex/gender (OR:16.94).

RESUMO

To evaluate and compare the factor structure and reliability of EPDS and PHQ in antepartum and postpartum samples. Parallel analysis and exploratory factor analysis were conducted to determine the structure of both scales in the entire sample as well as in the antepartum and postpartum groups. McDonald's omega statistics examined the utility of treating items as a single scale versus multiple factors. Multigroup confirmatory factor analysis (MCFA) was utilized to test the measurement invariance between the antepartum and postpartum groups. Two-factor models fit best for the EPDS in both the antepartum and postpartum groups; however, the most reliable score variance was attributable to a general factor for each scale. MCFA provided evidence of weak invariance across groups regarding factor loadings and partial invariance regarding item thresholds. PHQ-9 showed a two-factor model in the antepartum group; however, the same model did not fit well in the postpartum group. EPDS should be preferred to PHQ-9 for measuring depressive symptoms in peripartum populations. Both scales should be used as a single-factor scale. Caution is required when comparing the antepartum and postpartum scores.

RESUMO

Objective: To provide a review of journal articles discussing clinical cases or vignettes of psychoanalysis or psychoanalytic psychotherapy of patients affected by bipolar disorder. Methods: A thorough search of journal articles was performed in five databases to identify studies published from 1990-2021. Results: Twenty-four articles were included in this review, comprising a total of 29 case reports. The most common theoretical approach adopted by the authors was "object relations." Two main sets of clinical-theoretical considerations and recommendations emerge: the applicability of analytic treatment to patients with bipolar disorder - taking into account their analyzability and practical arrangements for conducting therapy - and theoretical speculations on the nature and development of the illness, as well as on the conceptualization of its different phases. Conclusion: Our findings reveal that there is some psychoanalytic literature providing insight into the psychological dynamics and treatment of patients with bipolar disorder. Elaboration of this literature may help improve our understanding and provide more accurate and comprehensive descriptions of the intrapsychic and interpersonal dynamics of these patients, yielding potentially valuable information for clinical and research purposes, particularly with regard to reducing interpersonal conflict, and increasing insight and engagement with lifestyle changes and other behaviors likely to promote health and stability.

RESUMO

The purpose of this article is to narratively review the empirical literature on clinicians' emotional, cognitive, and behavioral responses (i.e., countertransference) to depressive and other symptoms of patients with mood disorders. Therapist subjective responses (countertransference) can negatively affect both diagnostic and therapeutic processes, especially when they are not recognized and managed promptly. However, at the same time, countertransference recognition, processing, and management can help inform the diagnostic process and improve the therapy process and outcome. In the last couple of decades, the number of studies that empirically explore countertransference toward mood disordered patients, as well as its relationship with various characteristics of both patients and treatment, has increased. Current evidence suggests that patients with depression tend to elicit more positive feelings among clinicians than patients with other severe mental disorders such as borderline personality disorder or schizophrenia. Furthermore, it documents the existence of associations between patients' severity of depressive symptoms and clinicians' subjective reactions, although the results regarding which specific countertransference patterns are evoked in relation to the different phases of the treatment are not entirely consistent. Lastly, growing evidence suggests the presence of clinicians' specific emotional reactions towards patients with suicidal ideation and behavior.

RESUMO

ABSTRACT: Instagram has grown in popularity among young adults and adolescents and is currently the second-favorite social network in the world. Research on its relationship to mental well-being is still relatively small and has yielded contradictory results. This study explores the relationship between time spent on Instagram and depressive symptoms, self-esteem, and disordered eating attitudes in a nonclinical sample of female Instagram users aged 18-35 years. In addition, it explores the mediating role of social comparison. A total of 1172 subjects completed a one-time-only online survey. Three different mediation analyses were performed to test the hypotheses that social comparison on Instagram mediates the association time spent on Instagram with depressive symptoms (model 1), self-esteem (model 2), and disordered eating attitudes (model 3). All three models showed that the relationship between intensity of Instagram use and the respective mental health indicator is completely mediated by the tendency for social comparison on Instagram.

RESUMO

Adolescence is characterized by emotional instability and risk-taking behaviours that can lead to, among other things, an increased risk of developing pathological video-gaming and gambling habits. The aim of this Study is to assess the prevalence and type of video gaming and gambling habits in adolescent students attending Italian upper-secondary schools. The cross-sectional study was conducted via an online survey using validated questionnaires. The primary outcome measures were the prevalence of past-year video gaming and gambling activities. The sample consisted of 502 adolescent students from first- and second-grade secondary schools. A total of 40.8% of participants were video gamers, 4.8% were gamblers, 17.8% were both video gamers and gamblers, and the remaining 36.6% were not players. Among participants who reported video gaming activity (n = 294), 68.0% were classified as nonproblem gamers, 24.5% as at-risk gamers, and 7.5% as disordered video gamers. Among the participants who reported gambling activity (n = 113), 85.8% were not problematic gamblers, 8.9% were at-risk gamblers, and 5.3% were pathological gamblers. Only 0.2% of all subjects met the criteria for both pathological gambling and pathological video game use. The findings indicate that video gaming and gambling are common leisure times among adolescent students. However, a small but significant minority of these adolescents met the criteria for either severe problem gaming or gambling or both.

RESUMO

INTRODUCTION: There is ongoing interest in using brief screening instruments to identify perinatal depression in clinical practice. One ultra-brief screening instrument for depression is the Patient Health Questionnaire-2 (PHQ-2), but thus far its accuracy in perinatal clinical practice has been barely researched. In the present study, we aimed to assess the screening accuracy of the PHQ-2 against the Patient Health Questionnaire-9 (PHQ-9) in a large sample of perinatal women. METHODS: A total of 1155 consecutive women attending 11 health care centers throughout Italy completed the PHQ-9 (which includes the PHQ-2) during pregnancy (27-40 weeks) or postpartum (1-13 weeks). Sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio positive, likelihood ratio negative, and overall accuracy were calculated using cut points 3 or greater and 2 or greater. RESULTS: During pregnancy, PHQ-2 greater than or equal to 3 revealed low sensitivity (38.4%-44.7%) but high specificity (97.8%-99.3%). In postpartum, it revealed moderate sensitivity (56.9%-70.6%), high specificity (95.8%-99.8%), and fair overall accuracy in pregnancy (70%). The alternative threshold greater than or equal to 2 revealed very high sensitivity (pregnancy: 92.1%-95.2%; postpartum: 87.1%-95.2%), moderate specificity (pregnancy: 78.1%-83.2%; postpartum: 68.8%-81.1%) and good overall accuracy, both during pregnancy (87%) and postpartum (84%). DISCUSSION: The PHQ-2 provided acceptable accuracy for screening for depression compared with the PHQ-9. In perinatal screening practice, a threshold of 2 or greater should be preferred as this ensures high sensitivity, missing only approximately 6% to 8% of cases, and a false-positive rate (percentage of women classified as affected with depressive symptoms when they are not) of 19% to 25%.

RESUMO

About a third of patients with major depressive disorder (MDD) do not have an adequate response to first-line antidepressant treatment, i.e., develop a treatment-resistant depression (TRD). The partial understanding of MDD pathophysiology currently constitutes the major barrier to clinical and research progress on this topic. However, recent advances in genome editing techniques as well as in induced pluripotent stem cells (iPSC) technology are offering unprecedented opportunities in both human disease modelling and drug discovery. These technology progresses have been enabling to set up disease-relevant patient-specific in vitro disease modeling for various mental disorders. The resulting models have the potential to significantly improve pathophysiologic understanding of MDD and then overcome some limitations inherent to animal and post-mortem models. More recently, psychiatry started to deal with the fast acting antidepressant ketamine and its derivates. Although ketamine appears to have the potential to transform the treatment of depression, its specific mechanisms of action are only partially known. Such knowledge is necessary to develop a model to understand the mechanisms behind fast-acting antidepressants, which may enable the discovery of novel glutamatergic compounds for the treatment of MDD. After discussing both the current understanding of ketamine's mechanisms of action, and the state of the art of human iPSC technology, the authors will introduce the implementation of a TRD model based on iPSC human technology and aimed at studying the ketamine's fast acting antidepressant mechanisms of action.

RESUMO

BACKGROUND: Growing empirical evidence suggests that adolescents have a relatively greater propensity to develop problematic video gaming or gambling habits. OBJECTIVE: The main objectives of this study are to estimate the prevalence of potential pathological gambling and video game use among adolescent students and to evaluate their risk factors. METHODS: This is a cross-sectional multi-informant study based on an online survey. It will include a sample of adolescents attending secondary schools located in Brescia, northern Italy, their schoolteachers, and parents. The survey includes extensive data on adolescents' (1) demographic, social, economic, and environmental characteristics; (2) behavioral, emotional, and social problems and adaptive functioning; (3) emotional and social loneliness; (4) perception of the reasons to use social networks; (5) video game habits and pathological use of video gaming; and (6) gambling behaviors. RESULTS: This protocol was approved by the Institutional Ethics Board of the Spedali Civili of Brescia (Italy). We expect to collect data from 793 or more adolescent students, as determined by our sample size calculation. CONCLUSIONS: This multisite project will make a substantial contribution to (1) the implementation of a system for identifying pathological gambling and pathological video game use among adolescents, allowing for interventions aimed at improving adolescents' financial, emotional, and social well-being; and (2) the identification of distinct profiles of gamblers and pathological video gamers that will contribute to setting up effective targeted prevention measures. Understanding the causes and impact of gambling and pathological video gaming on adolescents is a public health issue. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/33376.
