ABSTRACT

Deficits in social cognition and metacognition impact the course of psychosis. Sex differences in social cognition and metacognition could explain heterogeneity in psychosis. 174 (58 females) patients with first-episode psychosis completed a clinical, neuropsychological, social cognitive, and metacognitive assessment. Subsequent latent profile analysis split by sex yielded two clusters common to both sexes (a Homogeneous group, 53% and 79.3%, and an Indecisive group, 18.3% and 8.6% of males and females, respectively), a specific male profile characterized by presenting jumping to conclusions (28.7%) and a specific female profile characterized by cognitive biases (12.1%). Males and females in the homogeneous profile seem to have a more benign course of illness. Males with jumping to conclusions had more clinical symptoms and more neuropsychological deficits. Females with cognitive biases were younger and had lower self-esteem. These results suggest that males and females may benefit from specific targeted treatment and highlights the need to consider sex when planning interventions.

ABSTRACT

Subjects with first-episode psychosis experience substantial deficits in social cognition and metacognition. Although previous studies have investigated the role of profiles of individuals in social cognition and metacognition in chronic schizophrenia, profiling subjects with first-episode psychosis in both domains remains to be investigated. We used latent profile analysis to derive profiles of the abilities in 174 persons with first-episode psychosis using the Beck's Cognitive Insight Scale, the Faces Test, the Hinting Task, the Internal, Personal and Situational Attributions Questionnaire, and the Beads Task. Participants received a clinical assessment and a neuropsychological assessment. The best-fitting model was selected according to the Bayesian information criterion (BIC). We assessed the importance of the variables via a classification tree (CART). We derived three clusters with distinct profiles. The first profile (33.3%) comprised individuals with low social cognition. The second profile (60.9%) comprised individuals that had more proneness to present jumping to conclusions. The third profile (5.7%) presented a heterogeneous profile of metacognitive deficits. Persons with lower social cognition presented worse clinical and neuropsychological features than cluster 2 and cluster 3. Cluster 3 presented significantly worst functioning. Our results suggest that individuals with FEP present distinct profiles that concur with specific clinical, neuropsychological, and functional challenges. Each subgroup may benefit from different interventions.

ABSTRACT

INTRODUCTION: Cognitive-behavioural therapy (CBT) is the preferred treatment in cases of chronic insomnia disorder in adults. PATIENTS AND METHODS: Open pragmatic study of 32 patients after eight sessions of group CBT for insomnia. RESULTS: Remission (insomnia severity index: 0-7 points) and response (insomnia severity index drops to > 8) were 31.3% and 46.9% at one month (n = 32) and 42.8% and 52.4% at one year (n = 21), respectively, with an effect size of 1.9 at one month and 2.3 at one year. At one month, 40.6% met the criteria for a case of insomnia (according to the insomnia symptoms questionnaire), and at one year, 19%, with a significant improvement in the symptoms at night and the consequences during the day. The questions of the Pittsburgh Sleep Quality Index on insomnia and sleep efficiency also improved. The pre-sleep arousal scale (n = 7) showed a shift from significant somatic and cognitive arousal to no arousal at one month. In the sleep diaries, total sleep time increased by an average of 53 minutes at one month (n = 14) and 76 minutes at one year (n = 10), with an increase of more than 10% in 71.4% of patients at one month and at one year, and an average sleep efficiency of more than 85%. The effect size for total sleep time and sleep efficiency was between 0.7 and 1. CONCLUSIONS: Group CBT for insomnia appears to be an effective treatment option in a clinical setting.


TITLE: Terapia grupal cognitivo-conductual para el insomnio: evaluación de resultados tras su introducción en un departamento de salud.Introducción. La terapia cognitivo-conductual (TCC) es el tratamiento de elección en el trastorno de insomnio crónico en adultos. Pacientes y métodos. Estudio pragmático abierto de 32 pacientes tras ocho sesiones de TCC grupal para el insomnio. Resultados. La remisión (índice de gravedad del insomnio: 0-7 puntos) y la respuesta (caída del índice de gravedad del insomnio > 8) fue del 31,3% y 46,9% al mes (n = 32) y del 42,8% y 52,4% al año (n = 21), respectivamente, con un tamaño del efecto de 1,9 al mes y 2,3 al año. Al mes, el 40,6% cumplía criterios de caso de insomnio (según el cuestionario de síntomas de insomnio), y al año, el 19%, con una mejoría significativa de síntomas nocturnos y consecuencias diurnas. También mejoraron las preguntas del índice de calidad de sueño de Pittsburgh sobre el insomnio y la eficiencia del sueño. La escala de activación previa al sueño (n = 7) mostró un trasvase desde activación significativa somática y cognitiva a ausencia de activación al mes. En los diarios de sueño, el tiempo total de sueño aumentó 53 minutos de media al mes (n = 14) y 76 al año (n = 10), con un aumento superior al 10% en el 71,4% de los pacientes al mes y al año, y una eficiencia del sueño media superior al 85%. El tamaño del efecto para el tiempo total de sueño y la eficiencia del sueño estuvo entre 0,7 y 1. Conclusiones. La TCC grupal para el insomnio parece una opción terapéutica eficaz en un entorno clínico.

ABSTRACT

BACKGROUND: Aims were to assess the efficacy of metacognitive training (MCT) in people with a recent onset of psychosis in terms of symptoms as a primary outcome and metacognitive variables as a secondary outcome. METHOD: A multicenter, randomized, controlled clinical trial was performed. A total of 126 patients were randomized to an MCT or a psycho-educational intervention with cognitive-behavioral elements. The sample was composed of people with a recent onset of psychosis, recruited from nine public centers in Spain. The treatment consisted of eight weekly sessions for both groups. Patients were assessed at three time-points: baseline, post-treatment, and at 6 months follow-up. The evaluator was blinded to the condition of the patient. Symptoms were assessed with the PANSS and metacognition was assessed with a battery of questionnaires of cognitive biases and social cognition. RESULTS: Both MCT and psycho-educational groups had improved symptoms post-treatment and at follow-up, with greater improvements in the MCT group. The MCT group was superior to the psycho-educational group on the Beck Cognitive Insight Scale (BCIS) total (p = 0.026) and self-certainty (p = 0.035) and dependence self-subscale of irrational beliefs, comparing baseline and post-treatment. Moreover, comparing baseline and follow-up, the MCT group was better than the psycho-educational group in self-reflectiveness on the BCIS (p = 0.047), total BCIS (p = 0.045), and intolerance to frustration (p = 0.014). Jumping to Conclusions (JTC) improved more in the MCT group than the psycho-educational group (p = 0.021). Regarding the comparison within each group, Theory of Mind (ToM), Personalizing Bias, and other subscales of irrational beliefs improved in the MCT group but not the psycho-educational group (p < 0.001-0.032). CONCLUSIONS: MCT could be an effective psychological intervention for people with recent onset of psychosis in order to improve cognitive insight, JTC, and tolerance to frustration. It seems that MCT could be useful to improve symptoms, ToM, and personalizing bias.

ABSTRACT

Confabulation has been documented in schizophrenia, but its neuropsychological correlates appear to be different from those of confabulation in neurological disease states. Forty-five schizophrenic patients and 37 controls were administered a task requiring them to recall fables. They also underwent testing with a range of memory and executive tasks. The patients with schizophrenia produced significantly more confabulations than the controls. After correcting for multiple comparisons, confabulation was not significantly associated with memory impairment, and was associated with impairment on only one of eight executive measures, the Brixton Test. Confabulation scores were also associated with impairment on two semantic memory tests. Confabulation was correlated with intrusion errors in recall, but not false positive errors in a recognition task. The findings suggest that confabulation in schizophrenia is unrelated to the episodic memory impairment seen in the disorder. However, the association with a circumscribed deficit in executive function could be consistent with a defective strategic retrieval account of confabulation similar to that of Moscovitch and co-workers, interacting with defective semantic memory.

ABSTRACT

BACKGROUND: A form of confabulation has been documented in schizophrenia and appears to be related to the symptom of thought disorder. It is unclear whether it is associated with the same pattern of neuropsychological deficits as confabulation in neurological patients. METHOD: Thirty-four patients with chronic schizophrenia, including those with and without thought disorder, and 17 healthy controls were given a fable recall task to elicit confabulation. They were also examined on a range of executive, episodic and semantic memory tests. RESULTS: Confabulation was seen at a significantly higher rate in the schizophrenic patients than the controls, and predominated in those with thought disorder. Neuropsychologically, it was not a function of general intellectual impairment, and was not clearly related to episodic memory or executive impairment. However, there were indications of an association with semantic memory impairment. CONCLUSIONS: The findings support the existence of a form of confabulation in schizophrenia that is related to thought disorder and has a different neuropsychological signature to the neurological form of the symptom.
