Motivational factors in health and disease.

Evidence is reviewed that measures of motive strength, as measured through content analysis of associative thought, are related to physiological systems, the functioning of which affect health outcomes. Studies show that affiliative and power motive syndromes assessed in associative thought are associated with health and illness. A relaxed or easygoing affiliative motive syndrome characterizes insulin dependent Type I diabetics and can, if aroused, lead to poorer blood sugar control in such diabetics. A stressed power motive syndrome is associated with sympathetic activation, release of stress hormones, depressed immune functions, and greater susceptibility to infectious diseases. Affiliative trust and a greater sense of agency as measured in associative thought content are associated with better health. An intervention study and a longitudinal study have demonstrated that differences in the levels of these motivational variables are not simply the result of illness but lead to alterations in subsequent health status.

Affiliation motivation: people who need people ... but in different ways.

The Interpersonal Orientation Scale was developed to focus on four dimensions assumed to underlie affiliation motivation: social comparison, emotional support, positive stimulation, and attention. Factor analyses basically supported the proposed multidimensional construct. Evidence for the validity of the four dimensions was provided by their correlations with measures of constructs conceptually related to affiliation motivation and their lack of correlation with measures conceptually unrelated to affiliation motivation. Moreover, in a laboratory study, each motivational subscale tended to correlate most highly with role-played responses in a situation affording the relevant incentive type. Future research on social motivation and interaction will profit from identifying the particular incentives that are salient in a giving setting.

The impact of accuracy motivation on interpretation, comparison, and correction processes: accuracy x knowledge accessibility effects.

Four studies provide evidence for the notion that there may be boundaries to the extent to which accuracy motivation may help perceivers to escape the influence of fortuitously activated information. Specifically, although accuracy motivations may eliminate assimilative accessibility effects, they are less likely to eliminate contrastive accessibility effects. It was found that the occurrence of different types of contrast effects (comparison and correction) was not significantly affected by participants' accuracy motivations. Furthermore, it was found that the mechanisms instigated by accuracy motivations differ from those ignited by correction instructions: Accuracy motivations attenuate assimilation effects because perceivers add target interpretations to the one suggested by primed information. Conversely, it was found that correction instructions yield contrast and prompt respondents to remove the priming event's influence from their reaction to the target.

The "I," the "we," and the "when": a meta-analysis of motivational primacy in self-definition.

What is the primary motivational basis of self-definition? The authors meta-analytically assessed 3 hypotheses: (a) The individual self is motivationally primary, (b) the collective self is motivationally primary, and (c) neither self is inherently primary; instead, motivational primacy depends on which self becomes accessible through contextual features. Results identified the individual self as the primary motivational basis of self-definition. People react more strongly to threat and enhancement of the individual than the collective self. Additionally, people more readily deny threatening information and more readily accept enhancing information when it pertains to the individual rather than the collective self, regardless of contextual influences. The individual self is the psychological home base, a stable system that can react flexibly to contextual influences.

Neuroleptics block high- but not low-dose heroin place preferences: further evidence for a two-system model of motivation.

The researchers studied whether 2 separate motivational systems in the brain underlie the rewarding effects of morphine. The brainstem tegmental pedunculopontine nucleus (TPP) is involved in mediating the motivational effects of opiates in nondeprived (drug-naive) rats, whereas dopamine transmission is necessary in mediating the motivational effects of opiates in deprived rats (opiate withdrawal). The results show that heroin's motivational properties obey the same boundary between a nondeprived and a deprived motivational state. Bilateral ibotenic acid lesions of the TPP blocked the acquisition of a place preference for an environment paired with 0.05 mg/kg heroin (a dose that induces no withdrawal aversion) but had no effect on place preference for an environment paired with 0.5 mg/kg heroin (a dose that does induce withdrawal aversion). Dopamine antagonist pretreatment produced the opposite pattern of results.

Reactions to cognitive ability tests: the relationships between race, test performance, face validity perceptions, and test-taking motivation.

The relationships among race, face validity perceptions, test-taking motivation, and test performance on a cognitive ability test were examined. Undergraduates completed 2 parallel cognitive ability tests and a test reactions measure. Results showed that test-taking motivation was related positively to subsequent performance on a parallel test even after the effects of race and performance on the first test were controlled. The effect of race on subsequent test performance was found to be mediated partially by motivation that provided evidence that some portion of the Black-White difference in test performance may be explained through differences in test-taking motivation. Results also indicated that Black-White differences in face validity perceptions of the test may be a function of Black-White differences in test performance. Face validity perceptions of the test affected subsequent performance on the parallel test but only indirectly through test-taking motivation.

Relationship of personality to performance motivation: a meta-analytic review.

This article provides a meta-analysis of the relationship between the five-factor model of personality and 3 central theories of performance motivation (goal-setting, expectancy, and self-efficacy motivation). The quantitative review includes 150 correlations from 65 studies. Traits were organized according to the five-factor model of personality. Results indicated that Neuroticism (average validity = -.31) and Conscientiousness (average validity = .24) were the strongest and most consistent correlates of performance motivation across the 3 theoretical perspectives. Results further indicated that the validity of 3 of the Big Five traits--Neuroticism, Extraversion, and Conscientiousness--generalized across studies. As a set, the Big Five traits had an average multiple correlation of .49 with the motivational criteria, suggesting that the Big Five traits are an important source of performance motivation.

The influence of positive affect on the components of expectancy motivation.

The influence of positive affect on expectancy motivation was investigated in 2 studies. The results of Study 1 indicated that positive affect improved people's performance and affected their perceptions of expectancy and valence. In Study 1, in which outcomes depended on chance, positive affect did not influence people's perceptions of instrumentality. In Study 2, in which the link between performance and outcomes was specified, positive affect influenced all 3 components of expectancy motivation. Together, the results of Studies 1 and 2 indicated that positive affect interacts with task conditions in influencing motivation and that its influence on motivation occurs not through general effects, such as response bias or general activation, but rather through its influence on the cognitive processes involved in motivation.

When self-efficacy negatively relates to motivation and performance in a learning context.

Recent reviews of the training literature have advocated directly manipulating self-efficacy in an attempt to improve the motivation of trainees. However, self-regulation theories conceive of motivation as a function of various goal processes, and assert that the effect of self-efficacy should depend on the process involved. Training contexts may evoke planning processes in which self-efficacy might negatively relate to motivation. Yet the typical between-persons studies in the current literature may obscure the effect. To examine this issue, 63 undergraduate students completed a series of questionnaires measuring self-efficacy and motivation before 5 class exams. Self-efficacy was negatively related to motivation and exam performance at the within-person level of analysis, despite a significant positive relation with performance at the between-persons level.

Majority and minority influence in group negotiation: the moderating effects of social motivation and decision rules.

In organizational groups, often a majority has aligned preferences that oppose those of a minority. Although such situations may give rise to majority coalitions that exclude the minority or to minorities blocking unfavorable agreements, structural and motivational factors may stimulate groups to engage in integrative negotiation, leading to collectively beneficial agreements. An experiment with 97 3-person groups was designed to test hypotheses about the interactions among decision rule, the majority's social motivation, and the minority's social motivation. Results showed that under unanimity rule, minority members block decisions, thus harming the group, but only when the minority has proself motivation. Under majority rule, majority members coalesce at the minority's expense, but only when the majority has a proself motivation. Implications for negotiation research and group decision making are discussed.

Effects of implicit power motivation on men's and women's implicit learning and testosterone changes after social victory or defeat.

Two studies examined interactions of implicit power motivation and experimentally varied victory or defeat in a contest on implicit learning of a visuomotor sequence associated with the contest outcome and changes in testosterone and self-reported affect. In men and women, power motivation predicted enhanced learning (sequence-execution accuracy) after a victory and impaired learning after a defeat. In men, power motivation predicted testosterone increases among winners and decreases among losers, and testosterone decreases mediated the negative effect of power motivation on learning in losers. In women, power motivation predicted postcontest testosterone increases, particularly among losers. In both men and women, self-reported affective states were influenced only by contest outcome and were unrelated to participants' testosterone changes or implicit learning.

Striving for unwanted goals: stress-dependent discrepancies between explicit and implicit achievement motives reduce subjective well-being and increase psychosomatic symptoms.

Three studies investigated the relevance of affect regulation, stressful life events, and congruence between explicit achievement orientation and implicit achievement motive for subjective well-being and symptom formation. According to personality systems interactions (PSI) theory, stressful life events were expected to reduce motive congruence when the ability to self-regulate affect was impaired (i.e., state orientation). Consistent with expectations, the State Orientation x Stress interaction predicted incongruence in healthy participants (Studies 1 and 3) and in patients (Study 2). Furthermore, incongruence partially mediated the direct State Orientation x Stress effect on subjective well-being (Studies 1 and 3) and the course of psychosomatic complaints over 3 months (Study 2). In Study 3, the experimental induction of threat reduced motive congruence in state-oriented participants compared with an acceptance condition. Findings underscore the importance of assessing motive congruence as a "hidden stressor" and validate a new operant multi-motive test.

Beyond self-esteem: influence of multiple motives on identity construction.

Diverse theories suggest that people are motivated to maintain or enhance feelings of self-esteem, continuity, distinctiveness, belonging, efficacy, and meaning in their identities. Four studies tested the influence of these motives on identity construction, by using a multilevel regression design. Participants perceived as more central those identity elements that provided a greater sense of self-esteem, continuity, distinctiveness, and meaning; this was found for individual, relational, and group levels of identity, among various populations, and by using a prospective design. Motives for belonging and efficacy influenced identity definition indirectly through their direct influences on identity enactment and through their contributions to self-esteem. Participants were happiest about those identity elements that best satisfied motives for self-esteem and efficacy. These findings point to the need for an integrated theory of identity motivation.

Adherence to antiretroviral therapy: an empirical test of the information-motivation-behavioral skills model.

Consistent and nearly perfect adherence is considered an essential requirement for HIV-positive patients on antiretroviral therapy (ART) to fully realize its life-extending benefits. The current study evaluated a comprehensive model of ART adherence--the information-motivation-behavioral skills (IMB) model. This model views adherence behavior as a function of the interrelations between adherence-related information, motivation, and behavioral skills. It hypothesizes that adherence-related information and motivation work through adherence-related behavioral skills to affect the initiation and maintenance of optimal ART adherence. In a series of structural equation models, the IMB model's critical constructs and assumptions were evaluated with a sample of 100 HIV-positive patients in clinical care. Across all analyses, the authors found support for the assumptions of the IMB model of ART adherence. Consistent with the model, adherence-related information and motivation related significantly to adherence-related behavioral skills, and behavioral skills related significantly to self-reported optimal adherence. Further, as predicted, the effects of information and motivation on self-reported adherence were mediated by adherence-related behavioral skills. Current study results are explored, and implications for adherence promotion interventions based on the model are discussed.

Motivation to volunteer by older adults: a test of competing measurement models.

Four measurement models of the structure of motivation to volunteer were evaluated in 2 samples of older (minimum age = 50 years), active volunteers. Motivation to volunteer was assessed with the Volunteer Functions Inventory. Whereas no support was found for either unidimensional or bipartite models, qualified support was observed for both 6-factor and 2nd-order factor models. The best fit of the data was obtained with the 6-factor model of motivation to volunteer (career, enhancement, protective, social, understanding, and values). Contrary to the prediction derived from the 2nd-order factor model, the 6 volunteer motives were differentially related to demographic variables and number of hours spent volunteering for the organization during the past year. Implications for assessing motivation to volunteer among older adults and recruiting older adults as volunteers are discussed.

Measuring college students' motives for playing drinking games.

Students may choose to play drinking games not only for reasons related to alcohol consumption but also because of incentives related to other aspects of play (competition, fun, interpersonal dominance, etc.). College students (120 men and 167 women) completed measures of motives for playing (based on T. J. Johnson, S. Hamilton, & V. L. Sheets, 1999) and consequences of playing drinking games. Exploratory principal-components analysis identified 8 reasons for playing. Men and women differed in their endorsement of the factors. Motives for play directly predicted consequences of play independently of alcohol consumption. Specific motives predicted specific types of consequences. In multiple regression analyses, Conformity motives were negatively related to consequences and may represent a form of protective motive.

Short-term effects of a brief motivational intervention to reduce alcohol and drug risk among homeless adolescents.

The short-term results of a randomized trial testing a brief feedback and motivational intervention for substance use among homeless adolescents are presented. Homeless adolescents ages 14-19 (N = 285) recruited from drop-in centers at agencies and from street intercept were randomly assigned to either a brief motivational enhancement (ME) group or 1 of 2 control groups. The 1-session motivational intervention presented personal feedback about patterns of risks related to alcohol or substance use in a style consistent with motivational interviewing. Follow-up interviews were conducted at 1 and 3 months postintervention. Youths who received the motivational intervention reported reduced illicit drug use other than marijuana at 1-month follow-up compared with youths in the control groups. Treatment effects were not found with respect to alcohol or marijuana. Post hoc analyses within the ME group suggested that those who were rated as more engaged and more likely to benefit showed greater drug use reduction than did those rated as less engaged. Limitations of the study are discussed as are implications for development of future substance use interventions for this high-risk group.

Substance use by college students: the role of intrinsic versus extrinsic motivation for athletic involvement.

Certain types of athletic involvement may confer risk for substance use by college students. This study investigated whether motivational factors play a role in the relationship between athletic involvement and substance use. Intercollegiate athletes (n=98) and exercisers (n=120) were surveyed about substance use and motivation for athletic involvement. Athletes and exercisers who were extrinsically motivated had significantly higher rates of alcohol use than their intrinsically motivated counterparts. Results suggest that college students who are extrinsically motivated for involvement in physical activity/athletics--particularly those involved in team sports--may be in need of targeted prevention efforts.
