Effect of incentives on retention in an outpatient treatment for cocaine addicts

The high drop-out rate in treatment programs is one of the most important problems in the area of drug addictions. This study evaluated the effect of the use of incentives on retention in an outpatient program for cocaine addicts. The effect of individual variables on program drop-out was also analysed. Participants were 66 subjects who were randomly assigned to one of three treatment groups: standard treatment, treatment with incentives I, and treatment with incentives II. The patients of these two groups received incentives contingent on cocaine abstinence with two different magnitudes. Retention rate at six months was 35% in the standard treatment, 78.6% in the treatment with incentives I, and 53.3% in the treatment with incentives II. The global prognostic capacity of the individual variables (sociodemographic, history and consumption pattern, psychopathological variables, and EuropASI scores) was 85.7%, with the psychopathological variables being more closely related to retention. These results suggest that the use of incentives may be an effective strategy to improve retention in outpatient treatments for cocaine addiction.     

Psychometric properties of a Multidimensional Scale of Social Expression to assess social skills in the Internet context

The increase in the use of New Technologies in social relationships could be generating a new paradigm in social skills. Valid and reliable instruments to assess these changes are needed. The aim of this study is to analyze the psychometric properties of the Multidimensional Scale of Social Expression (EMES) in the assessment of social skills on the Internet and Social Networks. A total of 413 college students from the province of Alicante participated on this study. The scale was applied according to two contexts: Real and Internet/Virtual. High internal consistency was shown. The 12-factor structure found for the Virtual Context scale is similar to that of the original study. The scale had shown to be a good predictor of hours of Internet use. In conclusion, EMES-C is useful for assessing real context and Internet context social skills.     

Financing A Voucher Program for Cocaine Abusers Through Community Donations in Spain

This study analyzed the viability of financing a voucher program for cocaine addicts in Spain through public and private donations. Of the 136 companies contacted, 52 (38%) provided donations. The difference between the benefits (15,670€/$20,371) and the costs (3,734€/$4,854) was 11,936€/$15,517. The type of reinforcer a company can offer, the size of the company, and the time elapsed before responding may be determining variables in a company''s decision whether to collaborate.     

Is previous experience important for inhibitory control? A comparison between shelter and pet dogs in A-not-B and cylinder tasks

This study compares the performance of two groups of dogs with different levels of social interaction with humans, shelter and pet dogs, in two inhibitory control tasks. (1) In the A-not-B task, dogs were required to resist searching for food in a previously rewarded location, and (2) in the cylinder task, dogs were required to resist approaching visible food directly in favor of a detour reaching response. Our first aim was to evaluate the importance of learning and ontogeny in performing inhibitory tasks. Also, we assessed whether there is a correlation between the two tasks by comparing performance in the same subjects. Results showed significant differences between shelter and pet dogs in the A-not-B task, with poorer performance in shelter dogs. However, no differences were found in the cylinder task. The poorer performance of shelter dogs might be related to their infrequent interaction with humans, which reduces the chances to learn to inhibit certain behaviors. This result would highlight the importance of ontogeny in developing that ability. On the other hand, no correlations were found between the two tasks, which contributes information to the debate about the context specificity of inhibitory control in dogs.     

Error monitoring recovery after abstinence and treatment in cocaine addicts / Recuperación del procesamiento de errores tras abstinencia y tratamiento en adictos a cocaína

Abstract

Cocaine addiction is associated with different cognitive functions. Error monitoring and inhibition of behaviour are of great significance, they are specifically relevant because of their connection with problems in decision making and relapse. The aim of this work is to not only study the deficits but also to see if recovery is possible after treatment and abstinence. We evaluated 23 participants with cocaine dependence and 23 control subject with a modification of the Eriksen Flanker Task. Participants with addiction showed lower scores than control subjects in congruent and incongruent conditions. As treatment time increased the number of correct responses improved, especially in post-error hits. We conclude that the processes of rehabilitation and detoxification could improve the ability to monitor errors and inhibiting behaviour.     

Diagnosis of cognitive impairment onset in older adults based on limitations in language skills / Diagnóstico del inicio del deterioro cognitivo en mayores a partir de limitaciones en las capacidades lingüísticas

Abstract

Progressive decline in language has been described in neuropsychological studies on Alzheimer’s disease and Mild Cognitive Impairment (MCI). We investigate this decline in its early stages, as well as its manifestations and the linguistic differences between participants at risk of developing MCI and without impairment. Participants were 36 older adults, all aged over 65. They were assessed using 31 subtests grouped into eight areas: fluency, comprehension, oral expression, reading, writing, memory, perceptual organization and processing speed. Our results showed significant differences between participants at risk of developing MCI and without impairment in verbal tests but not in manipulative tests. All participants at risk of developing MCI scored lowest in these eight areas. Our findings illustrate the relevance of investigating language skills in people at risk of developing MCI. Investigating these neuropsychological changes will help design appropriate intervention programmes that affect areas with higher levels of impairment.     

Gazing as a help requesting behavior: a comparison of dogs participating in animal-assisted interventions and pet dogs

Animal Cognition - Dogs tend to gaze at humans when they are confronted with inaccessible food during an unsolvable task, which is often interpreted as a help requesting behavior. Dogs who...
