Social support in the short- and middle-term prediction of welfare volunteers' permanence

This work explores the significance of different types and sources of social support in the short- and middle-term prediction of volunteer permanence. Volunteers ( N = 1362) belonging to 109 different Spanish organizations were surveyed to gather social support data and other information related to factors traditionally associated with sustained volunteerism prediction. In spite of the fact that a relationship between social support and permanence was found, logistic regression analysis showed that social support variables did not appear to be relevant to make this kind of prediction at short term, because the only factors associated with volunteers' permanence in the multivariate model obtained were the volunteers' previous time in the organization, their intention of remaining in service, and their sex and religious attitudes. In contrast, at middle term, social support and, in particular, informational social support from other volunteers was significant, integrating the multivariate model with the other aforementioned factors, except for sex.     

The relationship of marital satisfaction and social support to depressive symptomatology

The relationship between depressive symptomatology, as measured by the short-form Beck Depression Inventory (BDI), and two social support variables was assessed. Based on a sample of 131 married men and 136 married women, the results indicated that the quality of the marital relationship and the frequency of positive social contact with adults other than the spouse were significantly related to depressive symptomatology for both men and women. These two variables accounted for 16% of the variance in BDI scores. Further, analyses of risk for high BDI scores showed that individuals having the least support were 13 times more likely to be in the high-BDI group than individuals with the highest levels of social support. These results suggest that social isolation and marital discord are related to high BDI scores among married adults.     

Effects of subchronic administration of gammahydroxybutyrate (GHB) on spatial working memory in rats

GHB, a popularly known drug as "liquid ecstasy", is a substance with abuse potential. Among the possible described side-effects after the continued consumption of GHB are amnesia and deterioration of memory. Likewise, recent studies indicate the existence of neurotoxicity in certain brain regions after its prolonged treatment. The aim of this study was to examine the effect of the subchronic administration of GHB (10 and 100 mg/kg) on spatial memory and sensoriomotor reflexes in male rats, using the Morris water maze and a battery of sensoriomotor tests, respectively. The results indicated that animals treated with GHB (10 mg/kg) showed a greater latency of escape during the phase of acquisition in the days first and third of tests, as compared with the control group (p<0.05), as well as a deterioration of grasping reflex with the two doses of GHB (p<0.01). Numerous studies indicated that the medial prefrontal cortex is a crucial neuronal substrate in the working memory and grasping reflex modulation. These results suggest that prolonged administration of GHB could alter structure and/or function of the medial prefrontal cortex, as well as its interconnections with other brain regions involved in the evaluated cognitive and neurological processes.     

Subtypes of drug-addicts in treatment: empirical support for a distinction between Type A and Type B

This study examines the possibility of replicating and generalizing a multidimensional typology of drug-addicts by means of the evaluation of 320 participants who were receiving outpatient treatment for their problem of addiction. A two-stage cluster analysis was performed, revealing the existence of two typologies of consumers, called type A and Type B. The participants classified as Type B showed various indicators of chronicity (higher mean age, higher unemployment rate), more severity of their problem of drug consumption and of medical aspects, employment support, legal, family/social and psychiatric problems in comparison with Type A. Participants from the latter group reported active employment as their main source of income and they had consumed drugs for fewer years. However, they presented more severity associated with alcohol consumption. In view of these data, Type A is called functional drug-addict and Type B chronic drug-addict. Once the groups of drug-addicts were delimited, a more specific characterization was made, taking seven problem areas into account: medical, employment support, alcohol, drugs, legal, family/social, and psychiatric areas. As a general conclusion, more psychosocial severity was observed in Type B as compared with Type A. Lastly, the implications and usefulness of grouping drug-addicts into typologies is discussed.     

Complicated grief and suicidal ideation in adult survivors of suicide

While the prevalence of complicated grief has been demonstrated to be elevated in survivors of suicide, the association between complicated grief and suicidal ideation among adult survivors of suicide has not been explored. The purpose of the present study is to examine the association between complicated grief and suicidal ideation in suicide survivors. The Inventory of Complicated Grief and the Beck Depression Inventory were administered to 60 adult survivors within 1 month of a death by suicide of a family member or significant other. Complicated grief was associated with a 9.68 (CI: 1.036, 90.417) times greater likelihood of suicidal ideation after controlling for depression, suggesting that syndromal complicated grief heightens vulnerability to suicidal ideation. Clinicians may provide more comprehensive assessments by recognizing the possibility of suicidal ideation in those with complicated grief.     

Predictors of depression in caregivers of dementia patients: boundary ambiguity and mastery

This study examined the role of two perceptual variables in predicting the development of depressive symptoms in caregivers. The first, boundary ambiguity, refers to whether the dementia patient is perceived as psychologically in or out of the family system. The second, an orientation toward mastery, is related to how persons manage various stressful situations, including caring for a dementia patient. This study included 70 patients and their caregivers. Stepwise regression and path analytic techniques were used to compare the impact of variables related to the illness per se and of variables related to caregivers' perceptions of their situations. Results indicate that both perceptual variables, boundary ambiguity, and mastery, are significantly related to a caregivers' depression level whereas severity of the patient's dementia is not. In sum, the more a caregiver perceives a mate as psychologically absent, the less masterful and the more depressed she or he is.     

Assessment of the global intelligence and selective cognitive capacities in preterm 8-year-old children

The aim of this study was to assess various cognitive abilities such as attention, IQ, reasoning, and memory related to academic achievement in 8- and 9-year-old preterm children. A total of 141 children were assessed. The preterm group (=37 weeks) comprised 63 children and was compared to 78 full-term children. Attention was evaluated using the d2 Selective Attention test, and the IQ by the L-M form of the Stanford-Binet Intelligence Scale, establishing a profile of abilities: perception, memory, comprehension, reasoning, and verbal fluency. Significant differences in IQ were found between the preterm and full-term children. Of the cognitive abilities assessed, the only significant differences were found in verbal fluency, with preterm boys showing lower verbal fluency scores than full-term children. In conclusion, all preterm groups have attention ability similar to that of full-term children. However, preterm children obtain lower scores in intelligence measures. In addition, preterm boys have verbal fluency difficulties. Taking into account the increase in preterm births, suitable intervention programs must be planned to attend the difficulties found.     

Sport stacking in auditory and visual attention of grade 3 learners

The effect of sport stacking on auditory and visual attention in 32 Grade 3 children was examined using a randomised, cross-over design. Children were randomly assigned to a sport stacking (n=16) or arts/crafts group (n=16) with these activities performed over 3 wk. (12 30-min. sessions, 4 per week). This was followed by a 3-wk. wash-out period after which there was a cross-over and the 3-wk. intervention repeated, with the sports stacking group performing arts/crafts and the arts/crafts group performing sports stacking. Performance on the Integrated Visual and Auditory Continuous Performance Test, a measure of auditory and visual attention, was assessed before and after each of the 3-wk. interventions for each group. Comparisons indicated that sport stacking resulted in significant improvement in high demand function and fine motor regulation, while it caused a significant reduction in low demand function. Auditory and visual attention adaptations to sport stacking may be specific to the high demand nature of the task.     

Parenting practices and internalizing and externalizing problems in Spanish adolescents

The goal of this study was to analyze the relationship between parenting practices and internalizing and externalizing problems presented by a group of adolescents according to their gender. Four hundred and sixty-nine secondary school students (aged between 12 and 18) participated in this study. The adolescents presented differences in perception of the educational practices of both parents as a function of their gender. Negative parenting practices were positively related to adolescents' internalizing and externalizing problems, whereas positive practices were negatively related to externalizing problems. Moreover, differences between boys and girls were found in predictor variables of problems, and the predictive power of the variables was higher for externalizing problems.
