Cognitive-behavioural treatment of pathological gambling in individuals with chronic schizophrenia: a pilot study

The current study aimed to test the clinical effectiveness of a cognitive-behavioural program (CBT) specifically adapted for pathological gamblers with chronic schizophrenia, carried out in a naturalistic setting of community Mental Health Centres. Forty-four pathological gamblers with chronic schizophrenia were assigned either to a standard drug therapy for schizophrenia (control group) or to cognitive-behavioural therapy for pathological gambling plus a standard drug therapy for schizophrenia (experimental group). Psychological treatment comprised a 20-session program including psychoeducation, stimulus control, gradual exposure and relapse prevention. Therapeutic success was defined as abstinence or the occurrence of only 1 or 2 episodes of gambling during the follow-up period. While the patients treated in the experimental group showed a rate of success of 73.9%, only 19% of the participants belonging to the control group gave up gambling at the 3-month follow-up. The CBT group also did better than the control group in the number of gambling episodes and in the amount of money spent on gambling. However, the improvement of the experimental group was weaker at the 6- and 12-month follow-up. These findings support the beneficial effects of CBT as adjunctive therapy for patients with dual diagnoses (schizophrenia and pathological gambling).     

Spanish validation of an emotion-eliciting set of films

One of the main difficulties in the study of emotion is the induction of a real emotional response by means of artificial techniques. The aim of the current study is to validate the Spanish version of a set of films with the capacity to induce emotions (PIE) under laboratory conditions and to analyze its capacity to provoke differentiated basic emotions. A sample of 127 subjects took part in the study; 57 excerpts of Spanish-dubbed films with capacity in previous studies to induce 7 emotions: anger, fear, sadness, disgust, amusement, tenderness, and neutral emotion were used. Subjective emotional response was measured using the Self-Assessment Manikins and the Discrete Emotions Questionnaire. Films included showed a good capacity to induce positive and negative affects, high levels of emotional activation and variations in the perception of emotional control. They induced basic emotions of amusement and fear in a differentiated way. However, sadness and disgust could not be significantly differentiated from anger; or anger and tenderness from sadness. The PIE could be a useful tool for the experimental research of emotions in Spanish populations.     

Socio‐economic,socio‐political and socio‐emotional variables explaining school bullying: a country‐wide multilevel analysis

Why do some countries, regions and schools have more bullying than others? What socio‐economic, socio‐political and other larger contextual factors predict school bullying? These open questions inspired this study with 53.316 5th‐ and 9th‐grade students (5% of the national student population in these grades), from 1,000 schools in Colombia. Students completed a national test of citizenship competencies, which included questions about bullying and about families, neighborhoods and their own socio‐emotional competencies. We combined these data with community violence and socio‐economic conditions of all Colombian municipalities, which allowed us to conduct multilevel analyses to identify municipality‐ and school‐level variables predicting school bullying. Most variance was found at the school level. Higher levels of school bullying were related to more males in the schools, lower levels of empathy, more authoritarian and violent families, higher levels of community violence, better socio‐economic conditions, hostile attributional biases and more beliefs supporting aggression. These results might reflect student, classroom and school contributions because student‐level variables were aggregated at the school level. Although in small portions, violence from the decades‐old‐armed conflict among guerrillas, paramilitaries and governmental forces predicted school bullying at the municipal level for 5th graders. For 9th graders, inequality in land ownership predicted school bullying. Neither poverty, nor population density or homicide rates contributed to explaining bullying. These results may help us advance toward understanding how the larger context relates to school bullying, and what socio‐emotional competencies may help us prevent the negative effects of a violent and unequal environment.

Effect of locus of warning tone on auditory choice reaction time

Forty Ss pressed a left- or right-hand key depending on the ear in which they heard a 500-Hz stimulus tone. Half of the Ss were instructed to press the key on the same side as the ear stimulated (corresponding condition), while the other half pressed the key on the opposite side (noncorresponding condition). A 200-Hz warning tone preceded the stimulus tone by either 200 or 400 msec. The warning tone was presented to the left ear, the right ear, or to both ears in a predetermined random sequence. The locus of the warning tone affected RT on noncorresponding trials but not on corresponding trials. The effect consisted of a significant slowing of information processing on trials where the warning tone was contralateral to the response. Results were explained in terms of an initial tendency to respond toward the source of the warning tone.     

Perception of sweetness and bitterness in different vehicles

In the present study, we investigated taste-taste, taste-vehicle, and simultaneous taste-vehicle-taste mixtures. Subjects made estimates of the sweetness and bitterness of 27 stimuli. Sucrose (292, 585, and 1170 mM), caffeine (13, 26, and 52 mM), and binary mixtures of low (292-13 mM), middle (585-26 mM), and high (1170-52 mM) levels of both components were dispersed in water, carboxymethylcellulose (CMC) 1% w/v, and gelatin 6% w/v. The sweetness and bitterness of the sucrose-vehicle-caffeine combinations were significantly weaker than the respective sucrose-vehicle and caffeine-vehicle combinations. The emerged mutual suppressive effects were asymmetrical and persisted when both tastants were presented in CMC and gelatin. Moreover, the increase in vehicle consistency and the simultaneous addition of another taste reduced the perceived intensity of a taste either presented alone or dissolved in water. For both sweetness and bitterness, the total taste suppression observed was always significant.
