Motivation and the coping process of adults with disabilities: a qualitative study.

Adults with disabilities who have completed rehabilitation programs and have returned to active lifestyles are experts on the importance of motivation after an injury or an illness. This qualitative descriptive study was conducted with 9 men and 3 women who had completed a spinal cord injury rehabilitation program at a rehabilitation hospital. The subjects were asked two questions: What helped motivate you during rehabilitation to return to an active, productive life? and How did rehabilitation nurses and staff assist you with that process? An analysis of the interviews revealed five motivational categories--independence, education, socialization, self-esteem, and realization--within the specific themes of nursing and healthcare interventions. Gaining insight into the motivation of adults who have coped with disabilities effectively can help rehabilitation nurses determine how they can promote the motivation that clients need to achieve a quality lifestyle.

Use of the Apathy Evaluation Scale as a measure of motivation in elderly people.

Motivation plays an important part in an elderly individual's ability to recover from a disabling event. On the other hand, apathy is a lack of motivation. The Apathy Evaluation Scale (AES) is an 18-item instrument that rates a person's thoughts, actions, and emotions over the previous 4 weeks. The purpose of this study was to use the AES with 102 patients in a geriatric rehabilitation program to determine if it predicted improved function after rehabilitation. In addition, a short 7-item version of the AES was tested. A strong correlation was demonstrated between the 18-item AES and the 7-item AES, the Mini-Mental State Examination, and the Geriatric Depression Scale. In separate regression analyses, we found that admission function and both the 18-item and 7-item AES were significant predictors of discharge function, and that functional level at admission to rehabilitation accounted for 31% of the variance in function after rehabilitation. The findings suggest that the AES might be an appropriate measure of motivation in older adults and might predict success in rehabilitation. Moreover, the ability to identify patients with low motivation can alert healthcare providers to develop interventions to improve older adults' motivation and help them attain and maintain their highest functional level.

Geriatric rehabilitation: the influence of efficacy beliefs and motivation.

The theory of self-efficacy is that the more one believes in the efficacy of a specific activity, the more likely (motivated) one is to perform that activity. Most of the research into self-efficacy beliefs among older adults has been quantitative and has consistently supported the influence of those beliefs on behavior. However, it has not been established how efficacy beliefs actually influence motivation in older adults, or what sources of efficacy-enhancing information help strengthen those beliefs. The purpose of this study was to better understand the factors that influence the efficacy beliefs that motivate older adults in a rehabilitation program, and to uncover the relation between efficacy beliefs, motivation, and behavior (i.e., participation in rehabilitation activities). Seventy-seven older adults, 55 women and 22 men, in an inpatient geriatric rehabilitation program were interviewed. Through content analysis, 11 major themes were identified as factors that influence efficacy beliefs and motivate people to participate in rehabilitation: personal expectations, personality, role models, verbal encouragement, progress, past experiences, spirituality, physical sensations, individualized care, social supports, and goals. The findings support the theory of self-efficacy, and are best explained within a social cognitive theory framework.

Immediate early gene activity in song control nuclei and brain areas regulating motivation relates positively to singing behavior during, but not outside of, a breeding context.

In some species, such as songbirds, much is known about how the brain regulates vocal learning, production, and perception. What remains a mystery is what regulates the motivation to communicate. European starlings (Sturnus vulgaris) sing throughout most of the year, but the social and environmental factors that motivate singing behavior differ seasonally. Male song is highly sexually motivated during, but not outside of, the breeding season. Brain areas outside the song control system, such as the medial preoptic nucleus (POM) and ventral tegmental area (VTA), have been implicated in regulating sexually motivated behaviors in birds, including song. The present study was designed to explore whether these regions, as well as three song control nuclei [area X, the high vocal center (HVC), and the robust nucleus of the arcopallium (RA)], might be involved differentially in song produced within compared to outside of a breeding context. We recorded the behavioral responses of breeding and nonbreeding condition male starlings to the introduction of a female conspecific. Males did not show context-dependent differences in the overall amount of song sung. However, immunocytochemistry for the protein product of the immediate early gene cFOS revealed a positive linear relationship between the total amount of songs sung and number of cFOS-labeled cells in POM, VTA, HVC, and RA for birds singing during, but not outside of, a breeding context. These results suggest that these regions differentially regulate male song production depending on reproductive context. Overall the data support the hypothesis that the POM and VTA interact with the song control system, specifically HVC and RA, to regulate sexually motivated vocal communication in songbirds.

Motivation for giving birth after breast cancer.

BACKGROUND: Breast cancer at a young age threatens the natural developmental tasks that characterize this phase in life including parenthood. The dilemma of whether to give birth arises due to the potential medical, psychological and social implications of pregnancy, birth and child rearing after breast cancer. The purpose of this study was to investigate the positive and negative motivations toward childbirth of breast cancer survivors and their husbands. METHOD: Thirty breast cancer survivors and 13 husbands were compared to 29 healthy women and 15 husbands. The study included qualitative questions and quantitative measures including: a demographic and medical questionnaire, the Parenthood Motivation Questionnaire--Revised, the ENRICH Marital Satisfaction Scale, the Brief Symptom Inventory, the Impact of Events Scale, and the Mental Adjustment to Cancer Questionnaire. RESULTS: The experience of having breast cancer did not hinder overall positive motivations toward childbirth, nor did it increase overall negative motivations toward childbirth, among women and their husbands. However, there were several differences between the groups, which may reflect the illness experience. For example, breast cancer survivors and their husbands reported more negative motivations toward childbirth due to health concerns than did healthy women and their husbands.

Sexual motivation in the male rat: the role of primary incentives and copulatory experience.

Two experiments explored the motivational impact of primary incentive female cues on the operant behavior of sexually naive and experienced male rats. In the first experiment, a straight-arm runway was used to assess the subjects' motivation to approach a goalbox containing either male or female "targets." Twelve sexually naive Long-Evans males ran for: (1) an empty goalbox; (2) a male conspecific; (3) an ovariectomized (OVX) female; (4) an OVX female given estradiol; (5) or an OVX female treated with estradiol and progesterone. A perforated Plexiglas partition in the goalbox prevented the subject males from physically interacting with the targets, although olfactory, visual, and auditory cues were accessible. We hypothesized that subjects would manifest shorter run times (reflecting greater motivation) when the goalbox contained a receptive/proceptive female as opposed to a nonreceptive female target. Subjects' run times were ordered depending on the nature of the target (from slowest to fastest): empty goalbox, male conspecific, OVX female, OVX + estradiol female, and OVX + estradiol + progesterone female. As predicted, subjects ran significantly faster for a receptive/proceptive female than for a nonreceptive female, indicating that sexually naive males are inherently motivated by female precopulatory cues. In the second experiment, 30 sexually naive male subjects ran for a goalbox containing either a nonestrous (OVX) or an estrous (OVX + estradiol + progesterone) female. Following six trials, 10 males were allowed one intromission with a receptive female, 10 males experienced one ejaculation, and 10 remained sexually naive. Only those males having experienced an ejaculation subsequently decreased their run times for both nonestrous and estrous females, indicating that sexual reinforcement produced by ejaculation, but not intromission, further enhances the motivational impact of female incentive cues.

Antecedents of smoking cessation among adolescents: who is motivated to change?

BACKGROUND: In recent years many longitudinal studies have examined the predictors of smoking acquisition. However, only a few studies have focused on the precursors of smoking cessation. The current study is one of the first concentrating on longitudinal predictors of young people's smoking cessation. METHODS: Subjects were 215 smokers ages 14-15 years who were reinterviewed 3 years later. These smokers were allocated to four groups based on their motivation to quit and actual quitting behavior at the last wave. Independent variables were smoking-specific cognitions, social influences, and aspects of smoking habits. RESULTS: Univariate comparisons between the four groups showed that those with a positive attitude toward smoking and lower self-efficacy were less likely to be motivated to quit 3 years later. No long-term effects of environmental influences were found. Aspects of smoking habits, such as intensity and frequency of smoking, and the context of cigarette use affected the motivation to quit. Logistic regression analyses were conducted to examine differences in predictors between the groups in more detail. These analyses revealed that differences mainly in attitudes and self-efficacy affected whether subjects were absolutely not motivated to quit or had actually quit 3 years later. Differences in smoking behavior affected the allocation to the more closely related groups (e.g., preparing versus quitting). CONCLUSIONS: Adolescents' motivation to quit is affected by smoking-related cognitions and habitual factors. More research is needed to decide whether the relation between intensity and frequency of smoking and the likelihood to quit later on should be interpreted in terms of differences in smoking initiation or in terms of preparation to quit.

Application of the protection motivation theory to genetic testing for breast cancer risk.

BACKGROUND: Many women, even women at low risk, are interested in genetic testing for breast cancer risk. However, the test has little to offer for women at low to moderate risk. We applied the Protection Motivation Theory (PMT) to investigate predictors of women's motivation to obtain such a test. METHODS: Women at low to moderate risk (n = 330) were recruited through a physician network. They received an informational letter by mail and completed a telephone survey and a written baseline questionnaire. RESULTS: Structural equation analyses with motivation to test as the outcome variable showed that the full model was not supported by the data. However, modifications to the model resulted in good model fit and explained 51% of the variance. Women with increased breast cancer worries, which were influenced by perceived risk, and women who saw more disadvantages of not getting tested showed more motivation to pursue testing. Women who saw more advantages of not getting tested showed less motivation. CONCLUSIONS: Applying the PMT was helpful in determining factors that play a role in women's intentions to obtain genetic testing. Counseling should aim at decreasing perceived risk and breast cancer worries and include a discussion of the consequences of not getting tested.

Naloxone effects on sucrose-motivated behavior.

The opioid system plays an important role in feeding. In general, opioid agonists typically increase feeding and opioid antagonists decrease feeding in non-food restricted animals. In food restricted animals the effects of these drugs are substantially reduced. Opioid antagonists have shown a marked effectiveness at reducing consumption of sweet foods. Explanations for this robust effect have typically focused on drug induced changes in taste, taste perception, or palatability. The current study relates the effects of the opioid antagonist naloxone on motivation to obtain different sucrose concentrations to the drug's effects on unrestricted sucrose solution consumption. Changes in motivation to respond were assessed under a progressive ratio reinforcement schedule (PR) which required increased response cost for each successive unit of sucrose solution. Motivation, as measured by the PR, increased as sucrose concentration increased and naloxone produced a dose-dependent decrease in motivation to respond for a given sucrose concentration. Thus, the effectiveness of naloxone was indirectly related to strength of the sucrose concentration. Under unrestricted access to sucrose solutions, naloxone reduced consumption greatest under the higher concentrations. The data suggest at least part of naloxone's effects on sweet tasting food may be mediated through endogenous opioid reward systems that are reflected in measures of motivation.

Features of the coordinated activity functionally identified neurons in the hypothalamus in different motivational-emotional states.

Coordinated activity of hypothalamic neurons associated with motivational and reinforcing systems were studied in functional states arising from hunger, satiation following food deprivation, "victim" cries, and electrical stimulation of the emotionally positive (lateral hypothalamus, lateral preoptic region) and negative (dorsomedial tegmentum) reinforcing structures of the hypothalamus. Activity characteristics were reflected in the magnitude, sign, and dynamics of correlations, and depended on the ratio of motivational and emotional components of behavior. The reciprocal nature of the statistical significance of the activity of these neurons in conditions in which motivation and emotion dominated indicates that the differentiated motivational and emotional hypothalamic influences in cortical processes during learning are mediated via the coordinated activity of neurons in the motivational and reinforcing systems of the hypothalamus.

Brain neuronal mechanisms of motivation and reinforcement: systemic organization of behavior.

The concept of systemic quantitation of behavior was used to study the interaction between dominant motivation and reinforcement on brain neurons. Feeding and escape were used as experimental models. Results showed that feeding and escape motivations are based on the mechanisms of ascending activating influences of lateral or ventromedial hypothalamic centers, respectively, on cortical neurons. Feeding and escape motivations evoked by electrical stimulation of hypothalamus, or the ones occurring naturally, modify the responses of single neurons of sensorimotor and insular cortex to sensory stimuli, to microiontophoretic application of neurotransmitters and neuropeptides, and especially to reinforcement. Dominant motivations are reflected in the burst-like activity and in a specific pattern of interpulse intervals of single units in various brain structures. Reinforcement transforms this activity into a regular pattern and also changes the neuronal responses of hypothalamic feeding and escape centers, to electrical stimulation and to microiontophoretic application of oligopeptides. Specific patterns of the unit responses to conditioned stimuli in the course of consecutive reinforcement was determined. After several instances of reinforcement, especially after repetitive reinforcement, the brain neurons influenced by the dominant motivation begin to produce specific protein molecules that are important for organization of an appropriate type of behavior. This process can be blocked by protein synthesis inhibitors.

The motivational valence of nicotine in the rat ventral tegmental area is switched from rewarding to aversive following blockade of the alpha7-subunit-containing nicotinic acetylcholine receptor.

RATIONALE: Within the mammalian ventral tegmental area (VTA), nicotine produces both aversive and rewarding motivational effects. However, the specific neuronal nicotinic acetylcholine receptor (nAChR) subtypes responsible for these effects are not clearly understood. OBJECTIVES: In the present study, we challenged the motivational effects of nicotine directly in the VTA with nAChR subunit specific antagonists. METHODS: Using an unbiased place-conditioning procedure as a behavioural assay, we performed bilateral microinfusions of nicotine over a wide range of concentrations (0.008, 8, 24 and 48 nmol/0.5 microl) and challenged the aversive and reinforcing behavioural effects of these nicotine doses with co-administration of di-hydro-beta-erythroidine (DHbetaE) (5 or 50 nmol/0.5 microl), a nAChR antagonist with higher relative affinity for the alpha4beta2 nAChR subunit, methyllycaconitine citrate (MLA) (0.4 or 4 nmol/0.5 microl), a nAChR antagonist that displays greater relative affinity for the alpha7 nAChR, and the NMDA receptor antagonist, d-2-amino-7-phosphoheptanoic acid (AP-7; 18 nmol/0.5 microl). RESULTS: The alpha4beta2 antagonist DHbetaE blocked both the rewarding and aversive properties of intra-VTA nicotine. However, the alpha7 antagonist MLA blocked nicotine reward and switched the motivational valence of higher doses of nicotine (8-48 nmol/0.5 microl) from rewarding to aversive. The NMDA antagonist AP-7 blocked both the aversive and rewarding effects of intra-VTA nicotine. CONCLUSIONS: These results suggest a functional dissociation between nAChR neural substrates within the VTA that mediate the bivalent motivational properties of nicotine and further suggest that nicotine may produce its motivational effects through a glutamatergic mechanism.

Residential water consumption, motivation for conserving water and the continuing tragedy of the commons.

This paper explores the effect of the perception of externalities (PE) on residential water consumption. Externalities occur when individuals make decisions that harm others, without concern for the impact or feeling a need to compensate for the harm. The aim of this study was to investigate whether PE affects people's motivation to conserve water, and, consequently, the practice of residential water consumption. Two hundred eighty Mexican citizens responded to a questionnaire investigating how they perceived that other individuals in their community wasted water. Respondents were also asked about their motives to conserve water, and direct observations of individual water consumption were recorded. Results were processed within a structural equations model, which revealed that motives to conserve water significantly inhibit water consumption. Since the perception of extemalities also inhibits conservation motives, the resulting effect of PE on water consumption is positive. This result means that the more people perceive that others waste water, the less their conservation motives, and, therefore, the more their own water consumption.

Condom use at first intercourse with a new partner in female adolescents and young adults: the role of cognitive planning and motives for having sex.

This study examined the extent to which cognitive planning and motives for sex can explain condom use at first intercourse with young females' most recent partner. A total of 133 female adolescents completed a questionnaire on cognitive planning (i.e., mentally preparing oneself for discussing condom use and for managing condoms), motives for having sex (i.e., having sex to express love, to experience pleasure, to enhance mood, and to please others), and condom use at this particular occasion. Logistic regression analyses showed that condom use was positively related to cognitive planning with respect to discussing condom use and negatively related to the motive for having sex to enhance mood. Cognitive planning for the management of condoms did not have a significant overall effect on condom use, but it did appear to be very effective for those adolescents who had a low score on the motive for having sex to express love. It thus appears useful to strengthen the skills of adolescents to discuss the use of condoms. Furthermore, stressing the negative affective consequences of unsafe sex may be particularly effective for those who are inclined to have sex to enhance mood, while encouraging adolescents to make plans for the management of condoms is likely to positively affect the use of condoms among those who are not primarily motivated to express love by having sex.

Oral hygiene in the orthodontic practice: Motivation, responsibilities, and concepts.

This article describes our current oral health program. This program will continue to change as we learn more effective ways to communicate and offer instruction. The orthodontist and his staff are in a unique position to help patients become concerned about oral health. The cumulative effect of such patient educations is tremendous since hundreds of patients can be affected. Improving the effectiveness of an oral health program is an excellent opportunity to expand our service as health-care practitioners. A survey of dental home-care programs shows that a relationship exists between dentists' attitudes toward their programs and the degrees of success. Usually an oral health program will not become effective unless the orthodontist is motivated and accepts responsibility for motivating his staff and patients. The extent to which an orthodontist is enthusiastic and involves himself in oral health motivation will be reflected in how enthusiastic his auxiliaries are when instructing patients. If an orthodontist delegates both the motivational and instructional aspects of oral hygiene improvement to auxiliaries, his program will fall short of its potential effectiveness. A comment at each appointment telling the patient about his cleaning effectiveness is especially helpful. This feedback should be offered with kindness, objectivity, and respect for the patient. If an orthodontist feels impatient or frustrated, the patient will perceive this; perception of this negativity will frequently result in patient resistance to instruction and cooperation. When an orthodontist offers guidance in oral hygiene with sincere interest and respect, patients usually respond to his concern and become receptive to improving themselves. The extent to which we recognize a patient's "potential" to achieve excellent oral health, regardless of his present condition, will affect our ability to motivate that person. Our respect for patients will increase when we accept that nearly every patient has the inner capability for achieving excellent oral health. We have an opportunity to help patients recognize this potential. When patients recognize more of their potential, self-respect grows and they gain interest in caring for themselves.

Endogenous opioids and sexual motivation and performance during the light phase of the diurnal cycle.

The sexual motivation and performance of sexually experienced male rats were tested during the light phase of the diurnal cycle after treatment with saline or 1 mg.kg-1 naloxone in a bilevel testing box. The sexual motivation during the light phase, as assessed by the increase in anticipatory level changes prior to introduction of a receptive female on subsequent weekly sessions, was comparable to that during the dark phase. Opioid blockade reduced the increase of level changes, suggesting that endogenous opioids are involved in sexual motivation. The sexual performance was impaired during the light phase. Naloxone treatment failed to affect the sexual performance, other than that the post ejaculatory refractory period was increased. This increased latency to re-initiate copulation may be an expression of the reduced sexual motivation. It is concluded that endogenous opioids are not involved in the regulation of the impaired sexual performance during the light phase of the diurnal cycle. In contrast, the sexual motivation, which displays no marked diurnal variation, may be stimulated by endogenous opioids.

Motivational effects of opioids: influence of D-1 versus D-2 receptor antagonists.

An unbiased place preference conditioning procedure was used to: (i) characterize the motivational effects of dopamine (DA)-receptor antagonists and (ii) examine the role of D-1 versus D-2 DA receptors in mediating the reinforcing and aversive properties of opioids. Acute administration of the D-1 antagonist, SCH 23390 (0.001-0.5 mg/kg), produced conditioned place aversions. In contrast, the D-2 antagonists, (-)-sulpiride and spiperone, were motivationally neutral, lacking reinforcing or aversive effects. Chronic infusion of SCH 23390 (1.0 mg/kg per day) during the conditioning sessions abolished the reinforcing effect of the mu-opioid agonist, morphine, and the place aversions produced by the kappa-opioid agonist, U-69593, and the opioid antagonist, naloxone. D-2 antagonists were ineffective in modifying the motivational properties of opioid agonists and naloxone. These data demonstrate the involvement of D-1 but not D-2 receptors in the motivational properties of opioids and suggest that the D-1 receptor is critical for the expression of reinforcing and aversive motivational states.

Midbrain lesions eliminate sexual receptivity but spare sexual motivation in female rats.

To measure sexual motivation we have used a preference test paradigm which involves testing a female with a sexually active male and a sexually inactive castrate male at the same time. On the assumption that a sexually motivated female will choose to spend more time with a partner who can provide her with stimulation appropriate to her motivational state, a female can be said to be sexually motivated to the extent that she spends more time with the active male than with the castrate. We find that bilateral destruction of the midbrain peripeduncular region eliminates the lordosis reflex in female rats, and abolishes sexual soliciting darting responses. Lesioned females treated with ovarian hormones continue, however, to show a strong preference for a sexually active male over a castrate. Thus, although peripeduncular destruction eliminates copulatory behavior, such destruction appears to spare hormone dependent systems for sexual motivation.
