Wealthy families and their drug abusing adolescents

Abstract

Researchers have hypothesized that providing care to an elderly relative can negatively affect marital relationships of caregivers. However, no research has directly examined this issue. This study explored the impact of elderly depression and impairment, mental caregiving, caregiver/elderly person relationship closeness, spouse burden, and caregiver burden on caregiver marital happiness (and adjustment) in 90 multigenerational families. No significant relationship was found between these variables and caregiver marital adjustment. A causal model involving the six independent variables and caregiver marital happiness was developed and tested. Elderly depression and caregiver burden directly affected level of caregiver marital happiness. The other four independent variables affected caregiver marital happiness indirectly through caregiver burden. Implications for marriage and family therapists are discussed.     

Life cycle and loss--the spiritual vacuum of heroin addiction

This research studied the function of heroin addiction as a family-learned method of coping with death, separation, and loss across the life cycle. Heroin addicts, psychiatric outpatients, and normal students were given an extensive interview and test battery to determine the incidence of loss of family members and significant others. Because the impact of death is often overcome through religious rituals, this study also investigated the subjects' perception of their families' religious values and orientation to life's meaning and purpose. Results indicate that the incidence of death differs significantly across groups and that addicts have a distinct orientation to death, are more suicidal, and have more premature and bizarre death experiences. During childhood they have more family separations, and they tend to develop a distinct pattern of continuously separating from and returning to their families. They are also less likely to have a clearly defined purpose in life. A subset of parents from each group were also interviewed and tested, and these results support the theory of the intergenerational transmission of behavior.     

Body image and drug addiction

Drawings of the inside of the body produced by 83 drug addicts were analyzed. For 75 men and 8 women, aged 18 to 30 years, their graphic productions were compared with those of children and adolescents without addiction problems. Results indicate that while children and adolescents represent anatomical parts, drug addicts tend to use the drawing to express their psychological difficulties using various metaphorical forms.     

奖赏对海洛因成瘾者执行功能的影响机制

一些研究发现海洛因成瘾者奖赏失调表现为:对海洛因相关线索的注意偏向、渴求感增加,对金钱奖赏表现出"即时收益优先"的高风险决策模式和对长时收益的敏感性降低。另一些研究发现海洛因成瘾者的执行功能存在障碍。奖赏失调和执行功能障碍在成瘾物质使用的维持和复吸中起着重要作用。双重竞争模型认为奖赏和执行功能的交互作用决定着行为的结果,但是奖赏对海洛因成瘾者执行功能的影响机制还不清楚。因此,拟使用事件相关电位技术来考察海洛因相关线索和金钱奖赏对不同戒断期成瘾者执行功能的影响机制,短期(1~3个月)、长期(18个月以上)海洛因戒断者和健康对照组被比较。这不仅有助于构建完善的成瘾理论体系,还有助于确定临床戒断后复吸的风险因素和不同戒断期的治疗目标。     

Limbic-striatal memory systems and drug addiction

Drug addiction can be understood as a pathological subversion of normal brain learning and memory processes strengthened by the motivational impact of drug-associated stimuli, leading to the establishment of compulsive drug-seeking habits. Such habits evolve through a cascade of complex associative processes with Pavlovian and instrumental components that may depend on the integration and coordination of output from several somewhat independent neural systems of learning and memory, each contributing to behavioral performance. Data are reviewed that help to define the influences of conditioned Pavlovian stimuli on goal-directed behavior via sign-tracking, motivational arousal, and conditioned reinforcement. Such influences are mediated via defined corticolimbic-striatal systems converging on the ventral striatum and driving habit-based learning that may depend on the dorsal striatum. These systems include separate and overlapping influences from the amygdala, hippocampus, and cingulate and medial prefrontal cortex on drug-seeking as well as drug-taking behavior, including the propensity to relapse.     

Reflections during a study on family therapy with drug addicts

This article presents ideas and reflections emerging during a project on family therapy with drug abusers. Initially inspired by the writings of Stanton and Todd on the subject, the project developed into a recursive and self-reflective process, characterized by increasing doubts about the usefulness of categorization of families, of pre-planning therapy, and of the therapist as an "expert." The limitations of approaches that emphasize the importance of understanding the family structure as the basis for changing it are discussed, particularly with respect to how they decrease therapist flexibility and may block the family's finding their own solution. Alternative approaches to practice and research are also discussed, bearing on ideas particularly formulated by theoreticians and practitioners inspired by second-order cybernetics.
