PurposeWe developed and validated a measure that assesses the latent construct of sexual and reproductive empowerment among adolescents and young adults. A specific measure for this group is critical because of their unique life stage and circumstances, which often includes frequent changes in sexual partners and involvement from parents in decision-making.MethodsAfter formative qualitative research, a review of the literature, and cognitive interviews, we developed 95 items representing nine dimensions of sexual and reproductive empowerment. Items were then fielded among a national sample of young people aged 15–24 years, and those who identified as sexually active completed a 3-month follow-up survey. We conducted psychometric analysis and scale validation.ResultsExploratory factor analysis on responses from 1,117 participants resulted in the Sexual and Reproductive Empowerment Scale for Adolescents and Young Adults, containing 23 items captured by seven subscales: comfort talking with partner; choice of partners, marriage, and children; parental support; sexual safety; self-love; sense of future; and sexual pleasure. Validation using logistic regression demonstrated that the subscales were consistently associated with sexual and reproductive health information and access to sexual and reproductive health services measured at baseline and moderately associated with the use of desired contraceptive methods at 3-month follow-up.ConclusionsThe Sexual and Reproductive Empowerment Scale for Adolescents and Young Adults is a new measure that assesses young people’s empowerment regarding sexual and reproductive health. It can be used by researchers, public health practitioners, and clinicians to measure sexual and reproductive empowerment among young people.  相似文献

The involvement of dopamine receptors in the inhibitory effect of Cholecystokinin octapeptide on ingestive behaviour was investigated. Male rats were infused intraorally with a 1 M solution of sucrose and the amount ingested after treatment with the dopamine receptor agonist apomorphine was compared with that after treatment with Cholecystokinin octapeptide. The test allows a distinction between the consummatory aspects of ingestive behaviour, i.e. responses used to ingest food, from the appetitive aspects, i.e. responses used to obtain food, because it ignores the latter aspects. Comparisons were also made between the effects of apomorphine and Cholecystokinin octapeptide on pellet intake, a test in which the rat has to display appetitive ingestive behaviour. Injection of apomorphine (400 μg) increased the concentration of plasma apomorphine within 0.3 min and the concentration of dopamine in the cerebrospinal fluid within 1 min of injection and induced behavioural stereotypes within 10 min in food-deprived male rats. Plasma apomorphine and cerebrospinal fluid dopamine levels had decreased by 30 min and the behavioural stereotypies had decreased by 40 min after the injection. Injection of apomorphine also inhibited the consumption of food pellets and the ingestion of sucrose. Inhibition of pellet and sucrose ingestion paralleled the effect of apomorphine on Stereotypie behaviour. Thus, injection of a dopamine receptor agonist is followed by alterations in plasma levels of the agonist, cerebrospinal fluid dopamine levels and in Stereotypie and ingestive behaviour which occur in parallel, in an inverted U-shaped manner and with a temporal delay between each event. These results show a close correlation between dopamine receptor stimulation and inhibition of ingestive behaviour. However, reversal of the inhibitory effect of apomorphine on ingestive behaviour required pretreatment with a lower dose of a dopamine receptor antagonist (cis-flupentixol) (0.1 mg) than reversal of Stereotypie behaviour (0.8 mg). The effect of dopamine receptor stimulation on consummatory ingestive behaviour is thus relatively weak and not secondary to the induction of Stereotypic behaviour. Treatment with a high dose of cis-flupentixol (0.8 mg) caused a prolonged period of immobility but had no effect on the ingestion of sucrose. Dopamine receptor blockade, therefore, interferes with appetitive, but not consummatory ingestive behaviour. Injection of Cholecystokinin octapeptide (5 μg) suppressed pellet and sucrose intake in a manner comparable to that of apomorphine, but induced no behavioural stereotypes and caused a gradual, rather than inverted U-shaped, increase in the concentration of dopamine in the cerebrospinal fluid that did not correlate with the effect on ingestive behaviour. Furthermore, while the inhibitory effect of apomorphine on the ingestion of sucrose was reversed by pretreatment with a low dose of cis-flupentixol (0.1 mg), the inhibitory effect of Cholecystokinin octapeptide was only partially reversed by cis-flupentixol and a higher dose (0.8 mg) was required. Blockade of cholecystokinin-A receptors, by treatment with L-364,718, but not cholecystokinin-B receptors, by treatment with L-365,260, blocked the inhibitory effect of Cholecystokinin octapeptide and, by itself, L-364,718 increased the amount of ingested sucrose. The inhibitory effect of Cholecystokinin octapeptide on consummatory ingestive behaviour, which is mediated by cholecystokinin-A receptors, is likely to involve mechanisms in addition to dopaminergic ones.  相似文献

To study the possibility that release of dopamine in the brain mediates the inhibitory effect of Cholecystokinin octapeptide on ingestive behaviour, the effect of amphetamine on intake of pellets or an intraorally administered sucrose solution was compared with that of Cholecystokinin octapeptide. Additionally, comparisons were made between the effect of Cholecystokinin octapeptide and pargyline, a monoamine oxidase inhibitor, and α-methyl-ρ-tyrosine, a tyrosine hydroxylase inhibitor. While amphetamine dose-dependently inhibited pellet intake it failed to inhibit sucrose intake in doses which caused behavioural stereotypies (<800 μg). Cholecystokinin octapeptide (5 μg) inhibited ingestive behaviour in both tests. A very high dose of amphetamine (2 mg) was required to inhibit sucrose intake to a level comparable to that of Cholecystokinin octapeptide. Pargyline (5 to 25 mg) or α-methyl-p-tyrosine (25 to 100 mg) dose-dependently inhibited pellet intake but had only weak effects on the intake of sucrose. Pargyline increased the concentration of dopamine and 3-methoxytyramine in the dorsal striatum and decreased the concentration of 3,4-dihydroxyphenylacetic acid. α-Methyl-ρ-tyrosine decreased the concentration of dopamine and 3,4-dihydroxyphenylacetic acid, but not that of 3-methoxytyramine. Injection of amphetamine (2 mg), but not Cholecystokinin octapeptide, in rats pretreated with pargyline increased the concentration of 3-methoxytyramine in the dorsal striatum and this effect was blocked by pretreatment with α-methyl-ρ-tyrosine. Pretreatment with α-methyl-ρ-tyrosine partially reversed the inhibitory effect of Cholecystokinin octapeptide on sucrose ingestion, enhanced the effect of amphetamine but did not affect that of apomorphine, a dopamine agonist. The results support the possibility that the inhibitory effect of Cholecystokinin octapeptide on consummatory ingestive behaviour, in part, is mediated via release of dopamine in the brain.  相似文献

ABSTRACT

Discussions of the machinations of sex and pleasure (as distinct from sexuality and LGBTIQ issues) have largely been absent from Narrative practices and as a result, little has been documented on how Narrative practices could work in a sex and pleasure therapy context. This essay describes a sex-focussed group therapy project using Narrative practices conducted in Melbourne, Australia spanning 15 weeks from April 2015 to September 2015. This paper covers the structure, practices, learnings, cohort and context, and offers a rationale and structure for other therapists to consider when doing the same. It examines the value of group process when discussing sex and pleasure as a powerful tool to reduce the stigma of sex and bring pleasure forward as a valid reason for seeking therapy.  相似文献

Previous research of negative symptoms in schizophrenia has emphasized an anticipatory pleasure deficit, yet the relationship of this deficit to patients' motivation in everyday life is poorly understood. This study tested the link between anticipatory pleasure and two broad motivational systems that are said to regulate the intensity of approach and avoidance behavior, the Behavioral Inhibition system (BIS) and the Behavioral Activation System (BAS). It was hypothesized that high vulnerability for negative symptoms would be associated with low reward responsiveness and that this association will be mediated by the amount of anticipated pleasure. Students (n=171) with varying vulnerability for negative symptoms (assessed by the Community Assessment of Psychic Experiences) completed questionnaires regarding (a) anticipatory and consummatory pleasure, and (b) responsiveness to threat and reward. As hypothesized, anticipatory pleasure correlated significantly negatively with subclinical negative symptoms (r=−0.21) and significantly positively with BAS (r=0.55). Furthermore, evidence for a partial mediation effect was found. The findings support the notion of a close association between negative symptoms, the ability to anticipate pleasure and approach motivation that is evident even in healthy persons. It is suggested that the behavioral deficits immanent to negative symptoms reflect difficulties in the ability to translate emotions into motivation.  相似文献

Anhedonia, as a failure to experience rewarding stimuli, is a key characteristic of many psychiatric disorders including depression and schizophrenia. Investigations on the neurobiological correlates of reward and hedonia/anhedonia have been a growing subject of research demonstrating several neuromodulators to mediate different aspects of reward processing. Whereas the majority of research on reward mainly focused on the dopamine and opioid systems, a serotonergic mechanism has been neglected. However, recent promising results strengthen the pivotal role of serotonin in reward processing. Evidence includes electrophysical and pharmacological as well as genetic and imaging studies. Primate research using single-unit recording of neurons within the dorsal raphe nucleus argues for a serotonergic mediation of reward value, whereas studies using intracranial self-stimulation point to an important contribution of serotonin in modulating motivational aspects of rewarding brain stimulation. Pharmacological studies using agonists and antagonists of serotonergic receptor subtypes and approaches investigating an increase or decrease of the extracellular level of serotonin offer strong evidence for a serotonergic mediation, ranging from aversion to pleasure. This review provides an argument for serotonin as a fundamental mediator of emotional, motivational and cognitive aspects of reward representation, which makes it possibly as important as dopamine for reward processing.  相似文献

PURPOSE. Anhedonia is a challenging symptom of schizophrenia and remains largely recalcitrant to current pharmacological treatments. The goal of this exploratory pilot study was to assess if a cognitive–sensory intervention could improve anticipatory pleasure. DESIGN AND METHODS. Five participants meeting the Diagnostic and Statistical Manual of Mental Disorders (4th edition, Text Revision) criteria for schizophrenia, presenting severe anhedonia and stabilized on atypical antipsychotic medication, received between 10 hours and 25 hours of training. FINDINGS. Results show that the patients improved on the anticipatory scale of the Temporal Experience of Pleasure Scale. Daily activities of the patients were also increased. PRACTICE IMPLICATIONS. These preliminary data need to be interpreted with caution given the small sample of the study, but they offer promising paths to develop new interventions to alleviate anhedonia in schizophrenia.  相似文献

ABSTRACT

This article explores the phenomenon of ‘embodied longing’ through a sequence of creative and relational events in the author’s personal therapy with a male psychotherapist. Following the evolution of her somatic body map, crafted inside and outside of sessions, the author illustrates her dynamic engagement with ‘the other’ within and without as a woman in flesh and blood. Pivoting around cellular memory of her conception and loss of a twin brother shortly after conception, this article brings together sensuous exploration of sexuality and critical reflection on gender identity from the vantage point of pre-natal development.  相似文献
