RESUMEN
BACKGROUND: New advances in the field of machine learning make it possible to track facial emotional expression with high resolution, including micro-expressions. These advances have promising applications for psychotherapy research, since manual coding (e.g., the Facial Action Coding System), is time-consuming. PURPOSE: We tested whether this technology can reliably identify in-session emotional expression in a naturalistic treatment setting, and how these measures relate to the outcome of psychotherapy. METHOD: We applied a machine learning emotion classifier to video material from 389 psychotherapy sessions of 23 patients with borderline personality pathology. We validated the findings with human ratings according to the Clients Emotional Arousal Scale (CEAS) and explored associations with treatment outcomes. RESULTS: Overall, machine learning ratings showed significant agreement with human ratings. Machine learning emotion classifiers, particularly the display of positive emotions (smiling and happiness), showed medium effect size on median-split treatment outcome (d = 0.3) as well as continuous improvement (r = 0.49, p < 0.05). Patients who dropped out form psychotherapy, showed significantly more neutral expressions, and generally less social smiling, particularly at the beginning of psychotherapeutic sessions. CONCLUSIONS: Machine learning classifiers are a highly promising resource for research in psychotherapy. The results highlight differential associations of displayed positive and negative feelings with treatment outcomes. Machine learning emotion recognition may be used for the early identification of drop-out risks and clinically relevant interactions in psychotherapy.
RESUMEN
BACKGROUND: Cognitive impairment, mainly characterised by executive dysfunction, occurs in about half of cases in amyotrophic lateral sclerosis (ALS). There is evidence that gender influences some clinical features of the disease, but its influence on the cognitive spectrum is unknown. Our objective was to investigate the impact of gender on cognitive profiles of patients with ALS. METHODS: A retrospective study based on an exhaustive neuropsychological battery was performed in a group of 165 (70 females, 95 males) sporadic, non-demented patients with ALS compared with 134 healthy control participants. This assessment primarily focused on executive, memory and language functions. RESULTS: 47 (29%) patients revealed impairment in executive function and 30 (18%) patients revealed cognitive non-executive impairment. Independent from mood tone and clinical variables, a significantly greater executive impairment was determined in female patients than in male patients and control participants. The relative risk for ALS females having impairment in executive function compared with male patients was 2.6 (95% CI 1.6 to 4.4; p=0.0003). ALS females scored lower in Phonemic Fluency, Trial Making, and Wisconsin Card Sorting test. CONCLUSIONS: Results highlight a significant vulnerability of ALS female patients to develop cognitive dysfunctions peculiar to the disease, independently of bulbar onset. The explicative hypotheses of the data are focused on two interpretative lines not mutually exclusive: the role of gonadal hormones and gender-related brain asymmetry pre-existing to the disease. These findings, never reported before in the literature, can have important implications for models of ALS pathogenesis and for future clinical trial designs.

This study investigated the somatic underpinning of empathy using an interpersonal physiology approach. Thirty-nine dyads were formed by a "pseudo-patient" and a "listener" (a therapist, a psychologist, or a non-therapist). Dyadic physiological concordance in electrodermal responses and listeners' empathy were evaluated during simulations of clinical sessions. A significant positive correlation between empathy as perceived by pseudo-patients and physiological concordance was found, providing empirical evidence of a somatic underpinning of empathy. Moreover, therapists showed higher levels of physiological concordance and empathy, confirming the importance of psychotherapy training in managing clinical interactions.

Interest in the association between patient and therapist's motion synchrony and the working alliance has been growing in recent years. This interest is part of a larger effort in psychotherapy research to study how the working alliance, being central to the therapeutic process, develops over the course of therapy. However, while previous studies suggest that such an association between motion synchrony and the working alliance exists, there are mixed results regarding the direction of it. The present single-case study seeks to shed light on these mixed results with a multimodal perspective of nonverbal synchrony. That is, through an exploration of a single case, the present study explores physiological synchrony as an indicator of context in which motion synchrony is associated with the working alliance. For this aim, a single case was chosen from a randomized control trial investigating short-term psychodynamic treatment for major depressive disorder. Statistical analysis identified an interaction between physiological synchrony and motion synchrony in predicting working alliance levels. Findings show that in the context of an antiphase pattern of physiological synchrony (negative association between physiological measures of the two participants), there was a positive association between motion synchrony and the working alliance. This study emphasizes the potential of a multimodal approach, while suggesting a possible explanation for mixed results in current literature that focuses on the association between motion synchrony and the working alliance.

Anorexia nervosa (AN) patients and their family-members share alexithymia, anxiety, depression, and other psychological symptoms, in the context of altered attachment. These domains have been individually studied in the context of eating disorders; few attempts have been made to study their interaction, especially including family members. In this study, alexithymia, parental-bonding, and psychopathology were assessed in 32 Italian families consisting of an adolescent AN patient, a sibling, and their parents. We aimed to (a) describe a sample of Italian families with a child affected by AN, notably including siblings; (b) investigate interactions between assessed constructs in patients and their siblings; and (c) investigate possible intergenerational effects. Results showed high alexithymia and psychopathological symptoms in patients but not in siblings, although the latter reported high obsession-compulsion and paranoid ideation scores. Patients' and siblings' alexithymia correlated with psychopathology. Parents reported generally low alexithymia. Perceived parental bonding was found to be suboptimal in most participants, yet no clear relationship was found between specific parenting styles and other measured traits, nor did we find any other relevant intergenerational effect. Anorexia nervosa implies psychological difficulties for all family members. Siblings' psychopathological traits are especially concerning and currently understudied. Implications for future research and clinical interventions are discussed.
RESUMEN
The harmonium model (HM) is a recent conceptualization of the unifying view of psychopathology, namely the idea of a general mechanism underpinning all mental disorders (the p factor). According to HM, psychopathology consists of a low dimensional Phase Space of Meaning (PSM), where each dimension of meaning maps a component of the environmental variability. Accordingly, the lower thenumber of independent dimensions in the PSM, and hence its intrinsic complexity, the more limited the way of interpreting the environment. The current simulation study, based on a Convolutional Neural Network (CNN) framework, aims at validating the HM low-dimensionality hypothesis. CNN-based classifiers were employed to simulate normotypical and pathological cognitive processes. Results revealed that normotypical and pathological CNNs were different in terms of both classification performance and layer activation patterns. Using Principal Component Analysis to characterize the PSM associated with the two algorithms, we found that the performance of the normotypical CNN relies on a larger and more evenly distributed number of components, compared with the pathological one. This finding might be indicative of the fact that psychopathology can be modelled as a low-dimensional, poorly modulable PSM, which means the environment is detected through few components of meaning, preventing complex information patterns from being taken into account.

INTRODUCTION: The hypothesis of a general psychopathology factor that underpins all common forms of mental disorders has been gaining momentum in contemporary clinical research and is known as the p factor hypothesis. Recently, a semiotic, embodied, and psychoanalytic conceptualisation of the p factor has been proposed called the Harmonium Model, which provides a computational account of such a construct. This research tested the core tenet of the Harmonium model, which is the idea that psychopathology can be conceptualised as due to poorly-modulable cognitive processes, and modelled the concept of Phase Space of Meaning (PSM) at the computational level. METHOD: Two studies were performed, both based on a simulation design implementing a deep learning model, simulating a cognitive process: a classification task. The level of performance of the task was considered the simulated equivalent to the normality-psychopathology continuum, the dimensionality of the neural network's internal computational dynamics being the simulated equivalent of the PSM's dimensionality. RESULTS: The neural networks' level of performance was shown to be associated with the characteristics of the internal computational dynamics, assumed to be the simulated equivalent of poorly-modulable cognitive processes. DISCUSSION: Findings supported the hypothesis. They showed that the neural network's low performance was a matter of the combination of predicted characteristics of the neural networks' internal computational dynamics. Implications, limitations, and further research directions are discussed.

Simulación por Computador , Aprendizaje Profundo , PsicopatologíaRESUMEN
Psychotherapy research studies are increasingly focused on the clinical process, which has allowed for the definition of general models about clinical functioning and the role of the therapist. Embodiment-based research has shown that interpersonal processes, such as synchrony and attunement, are critical for the development of crucial therapist skills and that these mechanisms are mediated by physiological processes. Although the connection between these embodied processes and clinical practice is currently a topic of investigation in psychotherapy research, its implications for clinical training are potentially broad, but they remain unexplored. The present contribution proposes the idea of embodied trainings for psychotherapy trainees, which could support their acquisition of clinical skills through implicit, embodied, and affective learning. We present detailed potential mechanisms, study designs, and psychological variables that could be used to develop such an in vivo training and suggest some possible applications, ranging from biofeedback sessions to experimental settings and roleplaying. Additional research in this field can help bridge the gap between psychotherapy research and psychotherapy training, by overcoming some of the limitations of post-session and external evaluations, by enriching psychotherapy training programs, and by facilitating the implicit and automatic attunement of the attitudes of the students who will become tomorrow's therapists.
RESUMEN
Background: The study of Suicidal ideation (SI) in people bereaved through suicide (Suicide Survivors, SSs) could be hampered by the person's willingness to admit it, or by their limited awareness of it. Our main hypothesis is that SI is common in these people, especially if they are parents or children of the victim. For its potential in shedding light on specific unconscious processes, Rorschach test was chosen for our investigation, for the first time in SSs literature. Rorschach suicide ideation and selected variables were further analyzed to better delineate their psychological profile. Method: Rorschach according to Exner's Comprehensive System was administered to 21 people bereaved through suicide presenting as outpatients at SOPROXI Project Service-Padova Mental Health Center- and 23 healthy controls. Beck Depression Inventory (BDI) was routinely administered to SSs and considered in the study. Results: T-tests showed significantly higher mean SI score (S-Con) as it emerged from the Rorschach test S-Con scores in SSs compared to control participants. SI found only weak correlation with the BDI item in which SSs can explicitly state the desire for their death. Within-group analysis revealed higher S-Con mean scores in bereaved children and parents of the victim compared to other kind of kinships. Morbid content (MOR) has been fund as the most characterizing variable in SSs' S-Con in terms of effect size, followed by a low number of responses with an ordinary form (X +%). Human movements (M), Special Scores related to thought slippage (ALOG, FABCOM2, INCOM2, and CONTAM) and poor human representations (PHR) have been shown to be more significantly present in SSs compared controls. Discussion: Psychodynamic interpretations of our results are provided. Clinical practice should consider Rorschach as one of eligible tools of investigation on this field.
RESUMEN
Recent studies have described brain involvement, mainly at frontal level, in patients with spinal and bulbar muscular atrophy (SBMA), a rare adult-onset motor neuron disease caused by a CAG repeat in the androgen receptor (AR) gene. The aim of our research was to investigate the poorly characterized neuropsychological and psychological profile of these patients, on the basis of previous literature. We administered a neuropsychological screening and tests relating to cognitive and affective empathy, attributed to the theory of mind (ToM) framework, to 20 males with SBMA, and to age- and education-matched controls. Although patients' neuropsychological performance was unimpaired, a clear dissociation emerged between their cognitive and affective empathy. Patients had distinctive deficits in mentalizing, as assessed with the Faux Pas Test, whilst affective empathy (i.e., sharing experience), assessed with the Reading the Mind in the Eyes test, appeared to be preserved. The likely implications of subtle frontal lobe impairments on the one hand, and a protective influence of androgen insensitivity in these patients on the other, are discussed in the light of our results.

BACKGROUND: Amyotrophic lateral sclerosis (ALS) and its devastating neurodegenerative consequences have an inevitably psychological impact on patients and their caregivers: however, although it would be strongly needed, there is a lack of research on the efficacy of psychological intervention. Our aim was to investigate the effect of hypnosis-based intervention on psychological and perceived physical wellbeing in patients and the indirect effect on caregivers. METHODS: We recruited eight ALS volunteers patients as a pilot sample for an hypnosis intervention and self-hypnosis training protocol lasting 1 month. Anxiety and depression level was measured in patients and caregivers at pre and post treatment phase. Quality of life and perceived physical symptoms changes were also investigated in patients. RESULTS: One month pre-post treatment improvement in depression, anxiety, and quality of life was clearly clinically observed and confirmed by psychometric analyses on questionnaire data. Moreover, decreases in physical symptoms such as pain, sleep disorders, emotional lability, and fasciculations were reported by our patients. Improvements in caregiver psychological wellbeing, likely as a consequence of patients psychological and perceived physical symptomatology improvement, were also observed. CONCLUSION: To the best of our knowledge, even if at a preliminary level, this is the first report on efficacy psychological intervention protocol on ALS patients. The findings provide initial support for using hypnosis and self-hypnosis training to manage some ALS physical consequences and mainly to cope its dramatic psychological implications for patients and, indirectly, for their caregivers.
