| Resumen en inglés | Introduction: craving is an important criterion in the diagnosis of inhalant use disorder; detecting this condition in the inhalant addictive cycle can help in predicting prolonged abstinence or relapses.Objective: to describe the psychometric and clinimetric evidence of the craving scale in a sample of users.Method: a cross-sectional study with a non-probability sample of 76 adult participants. For the analysis, the sample was divided into two groups: inhalant use disorder group (n = 60) an experimental user group (n = 16). A craving scale for inhalants was applied. A descriptive, factorial analysis and a receiver operating characteristic curve (ROC) analysis were performed.Results: the ROC analysis to differentiate between users with inhalant users disorder and experimental users showed a cut-off point of 36 mm, with a sensitivity of .983 and a specificity of .813 (1= specificity of .187). The overall analysis showed that the craving scores of users with inhalant use disorder were considerably higher (M = 417.15, SD = 215) than experimental users (M = 185, SD = 136.25).Discussion and conclusions: clinical evidence showed a valid cut-off point to detect the presence of craving in inhalant users and this score can be used as an objective reference in clinical practice; the craving scale has adequate reliability and validity evidence.Objective: to evaluate the ability to perceive social cues, interpersonal attitudes and the communication of intentions by nonverbal expressive channels in patients with schizophrenia when compared with a control group.Method: a cross-sectional, comparative study (102 subjects, aged 18 to 45). The first group consisted of 50 patients with schizophrenia, (48% men) according to DSM-5 criteria. The second group consisted of 52 subjects (51.9% men) without psychopathology or history of mental disorders in first degree relatives, neurological deficits and intellectual disabilities. MiniPONS was used to assess social perception and the TAS-20 scale was used to assess alexithymia. We used 2 and Students t-tests, and an analysis of variance of two factors (group-sex) was used for MiniPONS and TAS scores. We searched for correlations between MiniPONS, alexithymia and PANSS.Results: we found a significant correlation between education and MiniPONS and TAS scores in the schizophrenia group: r = .36, p < .01 and r = -.46, p < .01, but not in the control group: r = .17, p = .41 and r = -.08, p = .71. The schizophrenia group performed worse on the MiniPONS: 39.90, SD = 5.99.Discussion and conclusions: our results show a worse overall performance in nonverbal communication and affect identification in the patient group. These failures exemplify the difficulty of understanding their own emotions. |
| Resumen en español | Introducción: el craving es un criterio importante en el diagnóstico del trastorno por uso de inhalables; detectar esta condición en el ciclo adictivo de los inhalables puede ayudar a predecir abstinencias prolongadas o recaídas.Objetivo: describir la evidencia psicométrica y clinimétrica de la escala de craving en una muestra de usuarios.Método: estudio transversal con muestra no probabilística de 76 participantes adultos. La muestra se dividió en dos grupos para el análisis: un grupo de usuarios con trastorno por uso de inhalables (n = 60) y un grupo de usuarios experimentales (n = 16). Se aplicó una escala de craving a inhalables. Se realizó un análisis descriptivo, factorial y un análisis de la curva característica operativa del receptor (ROC).Resultados: el análisis ROC para discriminar entre consumidores de inhalables y el grupo de usuarios experimentales mostró un punto de corte de 36 mm, con una sensibilidad de .983 y una especificidad de .813 (1= especificidad de .187). El análisis general mostró que las puntuaciones de craving de los usuarios con trastorno por uso de inhalables eran considerablemente más altas (M = 417.15, SD = 215) que en los usuarios experimentales (M = 185, SD = 136.25).Discusión y conclusiones: la evidencia clínica mostró un punto de corte válido para detectar la presencia de craving en usuarios de inhalables, y este puntaje puede ser utilizado como referencia objetiva en la práctica clínica; la escala de craving tiene evidencia adecuada de confiabilidad y validez. |
