Counterfactuals and motivation: mood as input to affective enjoyment and preparation.

Two studies demonstrated that moods, in interaction with motivational goals, can influence counterfactual thinking (mental simulations of 'what might have been'). This was shown for performances on laboratory tasks (Study 1) and for real-life course exams (Study 2). In Study 1, with enjoyment goals, participants in good moods generated the greatest number of downward (worse than actuality) counterfactuals; with performance goals, participants in bad moods generated the greatest number of upward (better than actuality) counterfactuals. Downward counterfactuals in good moods with enjoyment goals was reflected in concern with affective motives, positive moods and low preparation. Upward counterfactuals in bad moods with performance goals was reflected in concern with preparative motives, negative moods and high preparation. In Study 2, affective and preparative goals were manipulated directly, mirroring Study 1. After success, participants with affective goals generated the greatest number of downward counterfactuals, which was reflected in high enjoyment, positive moods and low preparation. After failure, participants with preparative goals generated the greatest number of upward counterfactuals, which was reflected in concern with performance, negative moods and high preparation. Discussion centres on implications for counterfactuals, self-motives and mood-as-input research.

A controlled study of a spirituality-focused intervention for increasing motivation for HIV prevention among drug users.

Spiritual Self-Schema (3-S) therapy is a manual-guided intervention for increasing motivation for HIV prevention that integrates a cognitive model of self within a Buddhist framework suitable for people of all faiths. In this controlled study, 72 methadone-maintained clients received either standard care and 8 weeks of 3-S therapy, or standard care alone. At treatment completion, 3-S clients reported significantly greater increases in spiritual practices, expression of spiritual qualities, and motivation for HIV prevention. They were also less likely to have engaged in HIV risk behavior. Correlational analyses showed that attendance at 3-S therapy sessions was significantly positively related to spiritual practice at treatment completion and to motivation for HIV prevention, and that both attendance at 3-S sessions and motivation for HIV preventive behavior were significantly negatively related to HIV risk behavior. Completion of 3-S therapy predicted posttreatment HIV preventive behavior, controlling for pretreatment behavior, demographics, and addiction severity measures (odds ratio = 8.89; 95% confidence interval = 1.62-48.93).

DeltaFosB in the nucleus accumbens regulates food-reinforced instrumental behavior and motivation.

Alterations in motivation have been implicated in the pathophysiology of several psychiatric disorders, including substance abuse and depression. Repeated exposure to drugs of abuse or stress is known to persistently induce the transcription factor deltaFosB in the nucleus accumbens (NAc) and dorsal striatum, effects hypothesized to contribute to neuroadaptations in dopamine-regulated signaling. Little is known, however, about the specific involvement of deltaFosB in dysregulation of appetitively motivated behaviors. We show here that inducible overexpression of deltaFosB in NAc and dorsal striatum of bitransgenic mice, or specifically in the NAc core of rats by use of viral-mediated gene transfer, enhanced food-reinforced instrumental performance and progressive ratio responding. Very similar behavioral effects were found after previous repeated exposure to cocaine, amphetamine, MDMA [(+)-3,4-methylenedioxymethamphetamine], or nicotine in rats. These results reveal the powerful regulation of motivational processes by deltaFosB, and provide evidence that drug-induced alterations in gene expression via induction of deltaFosB within the NAc core may play a critical role in the impact of motivational influences on instrumental behavior.

Lesions of the basolateral amygdala disrupt conditioning based on the retrieved representations of motivationally significant events.

One recent perspective (Blundell et al., 2001; 2003; Killcross and Blundell, 2002; Balleine et al. 2003) on the function of the basolateral region of the amygdala (BLA) suggests that it plays an important role in the representation of the sensory features of motivationally significant events. This predicts that lesions of the BLA will not produce a decrement in performance in conditioning procedures based on the formation of associations between the sensory aspects of neutral events but will interfere with conditioning based on associations between neutral cues and motivationally significant events. This prediction is supported by the evidence that BLA lesions were without effect on a sensory preconditioning procedure (experiment 1A) that used neutral cues but that BLA lesions did significantly impair representation-mediated conditioning (experiment 1B) when the target cues were motivationally significant at the time of training. These results demonstrate that animals with lesions of the BLA can represent the sensory aspects of neutral events but not the sensory aspects of motivationally significant events.

Subthalamic nucleus lesions enhance the psychomotor-activating, incentive motivational, and neurobiological effects of cocaine.

The subthalamic nucleus (STN) is traditionally thought to be involved in motor control, and dysfunction of the STN is thought to contribute to movement disorders. Here, we show that the STN also plays an important role in motivational processes and the response to drugs of abuse. Specifically, bilateral STN lesions produced a dose-dependent increase in the psychomotor-activating effects of cocaine, the rate at which animals acquired cocaine self-administration, and the motivation for cocaine assessed using a progressive ratio schedule. Furthermore, bilateral STN lesions enhanced the ability of cocaine to induce gene expression in the nucleus accumbens and caudate-putamen, two structures known to be involved in mediating the psychomotor-activating and incentive motivational effects of drugs of abuse. These findings suggest that engagement of the STN serves to dampen the psychomotor-activating and incentive motivational effects of drugs of abuse. Thus, the STN may serve as a novel target for therapeutic interventions aimed at treating drug dependence.

Findings of a pilot study of motivational interviewing with pregnant drinkers.

OBJECTIVE: Cost-effective interventions are needed for counseling pregnant drinkers, in order to reduce risk of fetal alcohol effects. METHOD: 42 pregnant women who reported alcohol consumption participated in this pilot study of motivational interviewing. Following a comprehensive alcohol use assessment, the participants were randomly assigned to receive either written information about the risks related to drinking during pregnancy or a one-hour motivational interview. The motivational interview was an empathic, client-centered, but directive session focusing on the health of the participants' unborn babies. RESULTS: At the end of a 2-month follow-up period, the 34 women (81%) who remained in the study showed a significant reduction in alcohol consumption and peak intoxication levels. Women who had reported the highest blood alcohol concentration (BAC) levels during early pregnancy showed a significantly greater reduction in their estimated BACs at follow-up (during later pregnancy) if assigned to the treatment rather than the control condition. CONCLUSIONS: Motivational interviewing shows promise as a specific intervention for initiating a reduction in drinking among pregnant women who are at greatest risk. Simpler assessment and advice may suffice for women with lower initial consumption levels.

Response inhibition under alcohol: effects of cognitive and motivational conflict.

OBJECTIVE: This experiment tested the effect of cognitive and motivational conflict on response inhibition under alcohol. METHOD: Fifty-six male social drinkers were randomly assigned to one of eight groups (n = 8). Four pairs of groups received 0.62 g/kg of alcohol, or a placebo, and each pair performed a go/stop choice reaction time task under one of four conflict conditions. One condition (C) produced cognitive conflict by presenting "go" and "stop" signals in the task. Another condition (IR) added motivational conflict by administering an equal monetary reward for inhibiting responses to stop-signals, and for responding to go-signals. The remaining two conditions resolved the motivational conflict by administering the monetary reward only for inhibitions (I), or only for responses (R). RESULTS: Compared with placebo, alcohol reduced inhibitions (i.e., impaired inhibitory control) under cognitive conflict (C; p = .041) and under motivational conflict (IR; p = .012). No significant effect of alcohol on inhibitions was observed in conditions where conflict was resolved (i.e., I and R). CONCLUSIONS: The study shows that alcohol can reduce the ability to inhibit a response. However, impaired inhibitory control is not an inevitable outcome of the drug action, because it can be counteracted by the consequences of behavior in the situation.

Illicit use of specific prescription stimulants among college students: prevalence, motives, and routes of administration.

OBJECTIVES: To explore the illicit use of specific prescription stimulants among college students and add to our understanding of reasons (motives) and routes of administration associated with illicit use of these drugs. METHODS: A random sample of 4580 college students self-administered a Web-based survey. The survey contained a variety of items pertaining to the illicit use of prescription stimulants. An extensive list of prescription stimulants was provided, and students were asked to select all the specific prescription stimulants that they had used illicitly. Items were also included to assess the motives and routes of administration associated with illicit use of prescription stimulants. RESULTS: Lifetime and past-year prevalence rates for illicit use of prescription stimulants were 8.3% (382 students) and 5.9% (269 students), respectively. Approximately three fourths (75.8%) of the 269 past-year illicit users of prescription stimulants reported using an amphetamine-dextroamphetamine combination agent (e.g., Adderall) in the past year, and approximately one fourth (24.5%) reported using methylphenidate (e.g., Ritalin, Concerta, Metadate, Methylin). Past-year illicit use of prescription stimulants was more than 3 times more likely among Caucasians (odds ratio [OR] 3.1, 95% confidence interval [CI] 1.5-6.6) and Hispanics (OR 3.8, 95% CI 1.6-9.3) compared with African-Americans, and more than twice as likely among Caucasians (OR 2.1, 95% CI 1.3-3.4) and Hispanics (OR 2.6, 95% CI 1.4-5.1) compared with Asians. The most commonly reported motives for illicit use were to help with concentration (65.2%), help study (59.8%), and increase alertness (47.5%). Other motives included getting high (31.0%) and experimentation (29.9%). Nearly every illicit user (95.3%) reported oral administration, and 38.1% reported snorting prescription stimulants. CONCLUSION: Illicit use of amphetamine-dextroamphetamine is more prevalent than illicit use of methylphenidate formulations among college students.

Coping, drinking motives, goal attainment expectancies and family models in relation to alcohol use among college students.

Associations between coping responses, drinking motivations, expectations of meeting social and academic goals, and family of origin problem drinking and measures of college students' quantity/frequency of alcohol use and social complications of alcohol use were investigated in a sample of 218 college students. Positive associations were found between "emotion-focused" forms of coping such as detachment and the criterion measures, whereas "problem-focused coping" was not significantly associated with quantity/frequency of alcohol use or drinking complications. Positive correlations were also found between drinking motives, goal attainment expectancies and family models measures and the criterion measures. Regression models constructed for alcohol quantity/frequency and drinking complications implicated the total number of drinking motives, family models of problem drinking and the coping strategy of self-blame as strongly related to criterion measures. Positive social drinking motives and coping by seeking social support were implicated as possible protective factors.

Life stage and motives for television use.

Do motives for using TV vary by viewer's age? Mass communication literature suggests that TV plays an important role in the life of younger and older persons in American society, but has not investigated how motives for viewing vary by age of the viewer or what needs are satisfied by viewing. A systematic random sample of telephone households in the Carbondale, DeSoto, and Murphysboro area of Southern Illinois provided 140 interviews with adults aged eighteen to eighty-seven. Life stage was related to five motives for using TV (to learn things, to forget, to overcome loneliness, to pass time when bored, and to find something to talk about). All but the forget/bored motive were positively correlated with age.

Addressing group dynamics in a brief motivational intervention for college student drinkers.

Previous research indicates that brief motivational interventions for college student drinkers may be less effective in group settings than individual settings. Social psychological theories about counterproductive group dynamics may partially explain this finding. The present study examined potential problems with group motivational interventions by comparing outcomes from a standard group motivational intervention (SGMI; n = 25), an enhanced group motivational intervention (EGMI; n = 27) designed to suppress counterproductive processes, and a no intervention control (n = 23). SGMI and EGMI participants reported disruptive group dynamics as evidenced by low elaboration likelihood, production blocking, and social loafing, though the level of disturbance was significantly lower for EGMI individuals (p = .001). Despite counteracting group dynamics in the EGMI condition, participants in the two interventions were statistically similar in post-intervention problem recognition and future drinking intentions. The results raise concerns over implementing individually-based interventions in group settings without making necessary adjustments.

Personal and social drinking motives, family drinking history, and problems associated with drinking in two university samples.

Two drinking motives scales, Negative Personal (NP) motives and Positive Social (PS) motives, derived from Mulford and Miller's Definitions of Alcohol Scales, and a Negative Family Models (NFM) scales designed to reflect family modeling of drinking-related problems were evaluated for internal consistency and association with college students' scores on a drinking-related Social Complications (SOCCOMP) scale. In both initial (n = 553) and cross-validation (n = 293) samples, all four scales demonstrated high internal consistency. Multiple regressions of NP, PS, and NFM scales, together with measures of quantity and frequency of drinking on SOCCOMP for both samples, yielded highly significant multiple R's, confirming the additive association of these measures with problem drinking outcomes. An unanticipated finding of positive associations between PS drinking motive and SOCCOMP is reported.

Age differences in self-appraisal motivation.

One hundred and eight young (mean age 29 years) and 108 older adults (mean age 69 years) participated in a laboratory investigation of self-appraisal motivation. Participants were recruited via media advertisement to take part in a study of two novel and different thinking abilities and randomly assigned to either a similar others, dissimilar others, or temporal-self comparison referent condition. Each participant was administered two tests purported to measure different thinking abilities and received experimenter-controlled test feedback intended to manipulate participants' level of uncertainty about these abilities. Motivation to self-appraise was assessed via behavioral choice measures collected following the inducement of uncertainty about ability status. Results indicated that older adults were less likely than the young to initiate behaviors that would reduce uncertainty about ability. Subsequent post-hoc analyses suggested that self-appraisal motivation in young adulthood is not moderated by level of perceived efficacy, while in later adulthood an attenuation of self-appraisal motivation occurs as a result of low efficacy or heightened uncertainty about one's capabilities.

Personal and social motivations as predictors of substance use among college students.

The Drug Use Survey was administered via a direct mail to a simple random sample of 2200 students enrolled at a large southwestern U.S. university. A purpose of the study was to determine the predictability of self-reported drug use utilizing motivations (personal and social) commonly reported by substance users. Two subscales were developed, one for each category of motivations. Reliability for each subscale as estimated by coefficient alpha was .80 and .86, respectively. A series of step-wise multiple regression analyses were computed in which individual drug use indices served as criterion variables, while the predictor variables were the personal motivations subscale (PMS) and the social motivation subscale (SMS) for each model. The results indicated that the PMS was the stronger predictor in every model with the exception of the model that predicted the alcohol use index. The SMS was the best predictor for alcohol use.

Supporting autonomy to motivate patients with diabetes for glucose control.

OBJECTIVE: We applied the self-determination theory of human motivation to examine whether patient perceptions of autonomy supportiveness (i.e., patient centeredness) from their diabetes care providers related to improved glucose control over a 12-month period. RESEARCH DESIGN AND METHODS: We conducted a prospective cohort study of patients with diabetes from a diabetes treatment center at a university-affiliated community hospital. Participants were 128 patients between 18 and 80 years of age who took medication for diabetes, had no other major medical illnesses, and were responsible for monitoring their glucose and taking their medications. The main outcome measure was a change in HbA1c values over the 12 months of the study RESULTS: Patient perception of autonomy support from a health care provider related to a change in HbA1c values at 12 months (P < 0.05). Further analyses showed that perceived autonomy support from the staff related to significant increases in patient autonomous motivation at 12 months (P < 0.05); that increases in autonomous motivation related to significant increases in perceived competence (P < 0.05); and that increases in a patient's perceived competence related to significant reductions in their HbA1c values over 12 months (P < 0.001). CONCLUSIONS: The findings support the prediction of the self-determination theory that patients with diabetes whose health care providers are autonomy supportive will become more motivated to regulate their glucose levels, feel more able to regulate their glucose, and show improvements in their HbA1c values.

Autonomous motivation: involvement in physical activity, and perceived sport competence: structural and mediator models.

Students in upper secondary school (N = 231, M = 16.6 yr., SD = 1.6) were tested on involvement in physical activity, perceived sport competence, using the Perceived Competence Scale of Harter, and motivational regulation on the Self-regulation Questionnaire of Ryan and Connell. Correlations were positive among involvement in physical activity, autonomous motivation, and perceived sport competence. A hypothetical model indicated that autonomous motivation mediates the relation between perceived sport competence and involvement in physical activity. Although LISREL analysis supported this mediation, the best model fit of the data supported a structural model with involvement in physical activity (R2 = .63) to mediate between autonomous motivation and perceived competence (R2 = .47). Results are interpreted and discussed in terms of self-determination theory.

Motives for participation in physical activity by Brazilian adults.

The present investigation examined the validity and reliability of a questionnaire which assessed motives of Brazilian adults for participation in physical activities, compared motives for participation in walking and fitness programs, and examined differences by sex, age, and education. Participants were 100 men and 138 women, ages 16 to 60 years (M=30.5, SD=11.4). Factor analysis identified four factors which were fairly consistent with previous research. Improvement in physical appearance and enjoyment were rated significantly more important reasons for participants in fitness programs than for walkers. Men were more motivated by social experience than women. Young adults rated importance lower in health and fitness and rated enjoyment, social experience, and improvement in appearance of higher importance. Health and fitness were considered more important by participants with more education. These results are consistent with previous research on the factors underlying motives for regular exercise and support the importance of considering differences associated with culture.

Music and movement education as a form of motivation in teaching Greek traditional dances.

Research has shown that motivation for participating in physical education, particularly in traditional dances, has decreased dramatically. The aim of this research was to examine whether a music and movement program would increase pleasure and intrinsic motivation of students in elementary education while teaching them Greek traditional dances. 232 students were divided into two groups, a trained group of 135 participants (72 boys, 63 girls) and a control group of 97 (53 boys, 44 girls). The trained group was taught using the music and movement teaching model of traditional dances. The control group was taught using the instructional or guided teaching method of traditional Greek dances. To measure effectiveness of the two methods was accomplished by the completion of McAuley's Intrinsic Motivation Inventory. Analysis of scores showed use of music and movement education had a positive effect on intrinsic motivation for dancing and active participation of students, especially of the trained boys' group.
