ABSTRACT

BACKGROUND: Self-guided web-based interventions have the potential of addressing help-seeking barriers and symptoms common among university students, such as depression and anxiety. Unfortunately, self-guided interventions are also associated with less adherence, implicating motivation as a potential moderator for adherence and improvement for such interventions. Previous studies examining motivation as a moderator or predictor of improvement on web-based interventions have defined and measured motivation variably, producing conflicting results. OBJECTIVE: This secondary analysis of data from a randomized controlled trial aimed to examine constructs of motivation as moderators of improvement for a self-guided 8-week web-based intervention in university students (N=1607). METHODS: Tested moderators included internal motivation, external motivation, and confidence in treatment derived from the Treatment Motivation Questionnaire. The primary outcome was an improvement in depression and anxiety measured by the Depression Anxiety Stress Scale-21. RESULTS: Piecewise linear mixed effects models showed that internal motivation significantly moderated symptom change for the intervention group (t1504=-2.94; P=.003) at average and high (+1 SD) motivation levels (t1507=-2.28; P=.02 and t1507=-4.05; P<.001, respectively). Significant results remained even after controlling for baseline severity. The results showed that confidence in treatment did not significantly moderate symptom change for the intervention group (t1504=1.44; P=.15). In this sample, only internal motivation was positively correlated with service initiation, intervention adherence, and intervention satisfaction. CONCLUSIONS: The combination of a web-based intervention and high or moderate internal motivation resulted in greater improvement in the total Depression Anxiety Stress Scale-21 score. These findings highlight the importance of conceptually differentiating motivation-related constructs when examining moderators of improvement. The results suggest that the combination of a web-based intervention and high or moderate internal motivation results in greater improvement. These findings highlight the importance of conceptually differentiating motivation-related constructs when examining moderators of improvement. To better understand the moderating role of internal motivation, future research is encouraged to replicate these findings in diverse samples as well as to examine related constructs such as baseline severity and adherence. Understanding these characteristics informs treatment strategies to maximize adherence and improvement when developing web-based interventions as well as allows services to be targeted to individuals likely to benefit from such interventions.

ABSTRACT

The application of green prevention and control techniques (GCTs) is a vital measure for improving the quality of agricultural products and enhancing the safety of the ecological environment and agricultural production. However, realistically, limited by the small-scale, part-time and decentralized business model, the adoption of GCTs by family farms in China faces practical problems such as insufficient internal transformation force and ability, as well as low external supervision efficiency. To reveal the directions of promoting family farms' GCTs adoption behavior, we establish a comprehensive theoretical model through the application of a novel integrated approach combining two dominant psychological theories of behavior change: the Theory of Planned Behavior (TPB) and the Norm Activation Model (NAM). We apply this framework to targeted research of vegetable growers in Henan Province in China using survey data (sample n = 653) analyzed through structural equation modeling (SEM). The integrated TPB-NAM model provides insight into both internal motivation and external environmental conditions for farmers' predicted adoption of GCTs. First, internal motivation, value cognition and personal norms are all driving factors affecting the GCTs behavioral intention of vegetable family farms. When GCTs are driven by the dual motivations of "self-interest" (personal norms) and "others-interest" (value cognition), personal norms can be activated by two factors: awareness of consequences and responsibility attribution. Furthermore, social norms, capital endowment and government regulation are the pressure and obstacle factors affecting the GCTs application of vegetable family farms. Social norms can indirectly affect the application of GCTs by forming personal norms. In addition, there are differences between the influencing factors and mechanism of GCTs adoption behavior intention of family farms of different sizes. Based on this, we propose some specific policy suggestions from three aspects: enhance value cognition, improve environmental awareness and responsibility perception, fill in the shortcomings of capital endowment, and implement differentiated incentive and restraint policies.

ABSTRACT

BACKGROUND: Intergenerational friendship, a mechanism of social support, is an effective intervention to reduce the increasing risk of social isolation (SI) and develop companionship in the older adult population. The COVID-19 pandemic provided a unique opportunity to examine the psychosocial intervention of befriending via technology use as a primary form of contactless socialization. OBJECTIVE: The study aims to explore the effectiveness of the befriending intervention through a contactless, intergenerational service-learning project on older adult emotions, especially boredom and loneliness as the key attributes of SI, and on students' attitude toward companionship. METHODS: During the months of January to April 2022 , undergraduate students enrolled in a health administration course with a special focus on culture were asked to be involved in a contactless, intergenerational service-learning project (n=46). In this study, contactless intervention meant communication using the telephone and apps such as FaceTime and Zoom. Students were paired with older adults to have at least a 30-minute weekly conversation, for 8 weeks, via telephone or an internet-based app such as FaceTime. Students were asked to write a half-page diary after each interaction and a 1-page reflection at the end of the fourth week and at the end of the service-learning project. At the completion of the project, the researchers also surveyed the older adults to assess the impact of the project using a 5-item open-ended questionnaire. Following a heuristic approach and content analysis, student artifacts (110,970 words; 118-page, single-spaced Microsoft Word document) and the older adult surveys were analyzed using MAXQDA, (VERBI GmbH). Qualitative data were extracted to assess the impact of service learning on SI by measuring the attributes of boredom and loneliness among 46 older adults. Students' attitudes toward companionship were also assessed using data from their diaries and reflections. RESULTS: Overall, three major constructs were identified: (1) meaningful engagement, defined as feeling safe, having increased confidence, and having reduced boredom; (2) internal motivation to participate in the weekly interaction, defined as discussion about daily life experience, level of happiness, and ability to exert personal control over the situation; and (3) intergenerational befriending, defined as perceived benefits from the friendly nature of the interaction, ability to comfortably connect with students, and positive feeling and attitude toward the student. CONCLUSIONS: The contactless, intergenerational befriending intervention reduced boredom and loneliness among older adults and enhanced positive attitude and confidence among university students. Students helped older adults to develop digital skills for the use of apps and social media. Older adults showed interest in the intervention and shared their daily life experiences with the students, which helped to reduce the gap between generations. Findings indicate the effectiveness of an intergenerational service-learning intervention on SI reduction and increased positive attitude among college students.

ABSTRACT

BACKGROUND: Residents completing competency-based medical education for postgraduate training face many challenging situations that may compromise their well-being or result in exhaustion or burnout. Factors described in self-determination theory and grit are important for residents' achievement of learning outcomes and well-being. This study explored the relationships among internal motivation, grit, well-being, and related factors among non-Western Asian residents. METHODS: We conducted an explanatory sequential mixed-methods survey-based study to explore correlations among satisfaction with basic psychological needs, grit, and well-being from September to November 2021 among residents at Ramathibodi Hospital, Mahidol University, Thailand. Data were collected with the Basic Psychological Needs Scale, Short Grit Scale, and World Health Organization-Five Well-Being Index. Next, participants with the highest and lowest scores for each scale were purposively invited to participate in semi-structured interviews. Interview data underwent thematic analysis and data collection continued until saturation was reached. RESULTS: In total, 245 residents (51% major ward, 65% female) completed the survey. There were strong associations between internal motivation, grit, and well-being (r = 0.46-0.90). Female residents had higher autonomy and relatedness scores than males (p = 0.04 and p = 0.01, respectively), and residents with less family responsibility had higher relatedness scores than other residents (p = 0.01). Residents who got more sleep had higher autonomy, relatedness, and well-being scores than those that slept less (p < 0.05). Residents who exercised > 5 times/week had higher well-being scores than other residents (p < 0.01). Thirty residents completed interviews. The thematic analysis revealed internal motivation, grit, and well-being were promoted by a supportive learning environment, a well-designed curriculum, actions and personalities of faculty members, and good personal factors. CONCLUSION: Internal motivation is significantly correlated with residents' grit, well-being, gender, family burdens, exercise, and sleep hours. Priority should be given to promoting internal motivation, grit, and well-being among residents by enhancing a positive learning environment, creating well-designed curricula, fostering good characteristics and actions among faculty members, and supporting residents' personal lives.

ABSTRACT

Compliance with health safety guidelines is essential during pandemics. However, political polarization in the U.S. is reducing compliance. We investigated how polarized perceptions of government leaders' autonomy-support and enforcement policies impacted security and internally-motivated compliance with national (Study 1a) and state (Study 1b) safety guidelines. We surveyed 773 Republicans and Democrats from four states (California, Florida, New York, Texas) during the first wave of the 2020 COVID-19 pandemic. Overall, participants perceived that the decision processes of opposing political administrations did not support their autonomy. Lack of autonomy-support was associated with reduced security and internal motivations to comply (R 2 = 50.83%). When political administrations enforced health safety mandates (Democrat state leaders in this study) and were perceived as autonomy-supportive, participants reported the highest security and internally-motivated compliance (R 2 = 49.57%). This effect was especially pronounced for Republicans, who reacted negatively to enforcement without autonomy-support. Political leaders who use fair and supportive decision-making processes may legitimize enforcement of health safety guidelines, improving compliance.

ABSTRACT

With a person-centered approach, the constellations of internal motivation and external motivation to respond without prejudice within individuals are examined, and how these relate to directly and indirectly reported levels of prejudice. Using latent profile analysis, we identified four subgroups of motivated individuals among large national samples of majority members in Germany (N = 1745) and in the Netherlands (N = 1645). With one exception, these subgroups differed in the proportion of prejudiced individuals as well as the average level of self-reported prejudice. Our findings make a contribution to the literature by highlighting the importance of considering how internal and external motivations are organized within individuals for understanding their prejudicial responses.

ABSTRACT

The response to visually evoked innate fear is essential for survival and impacts the cognition and behavior of animals to threats in the environment. However, contradictory findings of the interaction of fear and executive behaviors were reported by previous studies. To address this question, the present study investigated the effect of looming stimuli-driven visually innate fear on reward-associated conditioned response and reversal learning in mice with low or high motivation for sucrose. The mice with low motivation exposed to looming stimuli displayed reduced efficiency in the test of conditional response in the fixed ratio 1 schedule and impaired executive motivation as tested in the progressive ratio schedule of reinforcement. However, the high motivated mice exposed to looming stimuli showed an unaffected conditional response but an increased executive motivation. In the reversal learning program, looming stimuli at the middle stage caused deficits in cognitive flexibility in the mice with low and high motivation. Therefore, these results illuminate the impact of visually evoked innate fear on conditional response and reversal learning and further show that the impacts are relevant to internal motivation and external fear stimuli.

ABSTRACT

@#Introduction: Designing an engaging teaching strategy that enhances the clinical application of anatomy knowledge is important for effective learning. Hence, this study was carried out to evaluate the outcomes of team-based learning (TBL) approach on students’ learning during gross anatomy practical classes. Method: A randomised-controlled trial was conducted on 215 pre-clinical year medical students, who were divided into TBL and control groups. Both groups attended the same anatomy lecture before the practical session. The TBL group underwent three phases of activities, which were pre-practical assignment (Phase-1), individual and team readiness assurance tests followed by a debriefing session (Phase-2), and group application task (Phase-3). Concurrently, the control group received a reading material as their pre-practical assignment and attended a practical session in the form of an anatomy model demonstration. Pre- and post-practical assessments were measured 30 minutes before and after the practical sessions. The students’ cognitive engagement and motivation were also measured after the practical sessions. Results: The TBL group among the Year-1 students outperformed the control group in all the test performance measures. The TBL group of the Year-1 students was also found to have greater improvement of test scores compared to their control counterparts. The TBL group was found to have significantly higher cognitive engagement scores only among the Year-2 students. However, the internal motivation scores were not significant in both cohorts. Conclusion: These results indicate that the TBL session contributes positive outcomes to students’ learning in anatomy context.

ABSTRACT

Many developing countries are transitioning to integrated solid waste management systems that will likely have a recycling component for making them sustainable. There are several approaches to recycling, one being waste separation at the household level. Such an approach relies critically on the willingness of households to engage in source-separation. Many studies on recycling have been based on self-reported information on the willingness of households to participate in recycling programmes, should they be established; only few studies have been able to test what these intentions are by actual measurements of participation. The type of measurement for gauging success should be able to compare achievements against alternative approaches. This study is of particular interest to transitioning countries because it reports on a recycling programme in a small community that, even though voluntary in nature, has so far been sustained for almost three years. Available data on the amount of recycled beverage containers retrieved over a six-month period was analysed to assess the performance of the programme. A survey of households was performed among the community to understand the factors that may be contributing to such longevity. It was found that a major driver is the internal motivation of most of the community households for caring and preserving the environment. This is a necessary but not sufficient requirement, for it is doubtful whether the programme could have been sustained without an effective education programme and a system to make the process of retrieval easy. The education programme importantly linked recycling as a solution to an environmental problem plaguing the community. Moreover, the improvement in the environmental quality once the programme started was positive feedback to their recycling efforts. However, the ease at which recycled items could have been deposited was found to be the most essential factor. Inasmuch as the quantity of retrievals was a measure of the continued interest in recycling, a reliable estimate of the achieved fraction of beverage waste retrieval rates could not have been obtained with the most recent national waste characterization information. The reasons for this are explained.

ABSTRACT

The primary purposes of this study were to (i) assess levels of different types of work motivation in a sample of UK hospitality workers and make a cross-cultural comparison with Chinese counterparts and (ii) identify how work motivation and shame-based attitudes towards mental health explain the variance in mental health problems in UK hospitality workers. One hundred three UK hospitality workers completed self-report measures, and correlation and multiple regression analyses were conducted to identify significant relationships. Findings demonstrate that internal and external motivation levels were higher in UK versus Chinese hospitality workers. Furthermore, external motivation was more significantly associated with shame and mental health problems compared to internal motivation. Motivation accounted for 34-50% of mental health problems. This is the first study to explore the relationship between motivation, shame, and mental health in UK hospitality workers. Findings suggest that augmenting internal motivation may be a novel means of addressing mental health problems in this worker population.

ABSTRACT

BACKGROUND: Increasing repeat blood donation behavior is a critical public health goal. According to self-determination theory, the process of developing internal motivation to give blood and an associated self-identity as a blood donor may be promoted by feelings of "relatedness" or a connection to other donors, which may be enhanced through social relations and interactions. OBJECTIVE: The purpose of this report it to describe the development and pilot testing of a social networking-based (Facebook) intervention condition designed to increase feelings of relatedness via virtual social interaction and support. METHODS: To develop the intervention condition content, images, text, polls, and video content were assembled. Ohio University college students (N=127) rated the content (82 images/text) presented by computer in random order using a scale of one to five on various dimensions of relatedness. Mean ratings were calculated and analyses of variance were conducted to assess associations among the dimensions. Based on these results, the relatedness intervention was adapted and evaluated for feasibility, acceptability, and preliminary efficacy among 24 first-time donors, aged 18 to 24 years, in a 30-day pilot trial. Paired t-tests were conducted to examine change over time in relatedness and connectedness. RESULTS: The intervention condition that was developed was acceptable and feasible. Results of the uncontrolled, preintervention, and postintervention evaluation revealed that feelings of individual-level relatedness increased significantly after the intervention. CONCLUSIONS: By promoting first-time blood donor relatedness, our goal is to enhance internal motivation for donating and the integration of the blood donor identity, thus increasing the likelihood of future repeat donation.

ABSTRACT

BACKGROUND: When financial cuts are made, staff redundancies and reorganisation in the healthcare system often follow. Little is known how such cutbacks affect work motivation of nurses in primary health care. AIM: Examine the effects of cutbacks on motivating factors among nurses in primary health care. METHODS: A phenomenological approach involving a purposeful sample of ten nurses in primary health care. Average age 44. RESULTS: The participants identified the job itself, autonomy, independence, good communication with co-workers, and the potential for professional training, learning and development as the main internal motivational factors related to their work. However, increased stress and uncertainty, growing fatigue and understaffing were starting to have a negative impact on these internal motivational factors. Moreover, reduced opportunities for professional training and development had negative effects on the participants. Many saw these opportunities as a vital part of recognition for their job performance. Regarding external motivation, the factors identified were job security, salaries and rewards, and interaction with management. The participants expressed their interest in more consultation with managers and most preferred an increased flow of information from managers to staff members during cutbacks. Salaries, professional training opportunities and appreciation were rewards named by participants for a job well done. All agreed that salaries are stronger motivational factors than before cutbacks. CONCLUSIONS: In the case of cutbacks, nursing managers should increase consultations with staff and make sure that nurses maintain their independence, autonomy, opportunities for professional training as well as appreciation for job well done.

ABSTRACT

OBJECTIVE: There is a need to create a standard interactive anatomy lecture that can engage students in their learning process. This study investigated the impact of a new lecturing guideline, the Cognitive Load Theory-based Lecture Model (CLT-bLM), on students' cognitive engagement and motivation. METHODS: A randomised controlled trial involving 197 participants from three institutions was conducted. The control group attended a freestyle lecture on the gross anatomy of the heart, delivered by a qualified anatomist from each institution. The intervention group attended a CLT-bLM-based lecture on a similar topic, delivered by the same lecturer, three weeks thereafter. The lecturers had attended a CLT-bLM workshop that allowed them to prepare for the CLT-bLM-based lecture over the course of three weeks. The students' ratings on their cognitive engagement and internal motivation were evaluated immediately after the lecture using a validated Learners' Engagement and Motivation Questionnaire. The differences between variables were analysed and the results were triangulated with the focus group discussion findings that explored students' experience while attending the lecture. RESULTS: The intervention group has a significantly higher level of cognitive engagement than the control group; however, no significant difference in internal motivation score was found. In addition, the intervention group reported having a good learning experience from the lectures. CONCLUSION: The guideline successfully stimulated students' cognitive engagement and learning experience, which indicates a successful stimulation of students' germane resources. Stimulation of these cognitive resources is essential for successful cognitive processing, especially when learning a difficult subject such as anatomy.

ABSTRACT

Optimal control models of biological movements introduce external task factors to specify the pace of movements. Here, we present the dual to the principle of optimality based on a conserved quantity, called "drive," that represents the influence of internal motivation level on movement pace. Optimal control and drive conservation provide equivalent descriptions for the regularities observed within individual movements. For regularities across movements, drive conservation predicts a previously unidentified scaling law between the overall size and speed of various self-paced hand movements in the absence of any external tasks, which we confirmed with psychophysical experiments. Drive can be interpreted as a high-level control variable that sets the overall pace of movements and may be represented in the brain as the tonic levels of neuromodulators that control the level of internal motivation, thus providing insights into how internal states affect biological motor control.

ABSTRACT

Objective: The aim of this study was to identify associations of internal motivation, perceived health competency, and health literacy with primary and secondary cancer prevention. Methods: A telephone survey was conducted with a sample of 2,700, 30-69 year olds, proportionally extracted from Gangwon Province, South Korea. The dependent variables were actions in primary and secondary prevention and the explanatory variables were 13 questions in three areas: internal motivation (4 items), perceived health competency (4 items), and health literacy (5 items). Result: Multiple linear regression analysis showed that internal motivation, perceived health competency, and health literacy positively impacted primary prevention after controlling for gender and age. As internal motivation, perceived health competency, and perceived literacy increased by 1 point, primary prevention scores increased by 0.11, 0.11, and 0.07 points, respectively. In addition, logistic regression results for secondary prevention showed that health literacy had a positive impact on secondary behavior. As health literacy increased by 1 point, the odds ratio of the practice of secondary prevention was 1.4 times higher. Conclusion: This study suggests that primary and secondary prevention of cancer are significantly related to intrinsic motivation factors, perceived health competency, and actual health literacy. Health literacy concepts that cover the capacity of health management in comprehensive areas need to be applied to education and promotion for improvement of primary and secondary prevention of cancer.

ABSTRACT

BACKGROUND: The need to obtain food is a critical proximate driver of an organism's movement that shapes the foraging and survival of individual animals. Consequently, the relationship between hunger and foraging has received considerable attention, leading to the common conception that hunger primarily enhances a "food-intake maximization" (FIMax) strategy and intensive search. A complementary explanation, however, suggests a trade-off with precautions taken to reduce the risk of physiological collapse from starvation, under a strategy we denote as "energy-expenditure minimization" (EEMin). The FImax-EEmin trade-off may interact with the forager's hunger level to shape a complex (non-monotonic) response pattern to increasing hunger. Yet, this important trade-off has rarely been investigated, particularly in free-ranging wild animals. We explored how hunger affects the movements of adult griffon vultures (Gyps fulvus) in southern Israel. Transmitters combining GPS and accelerometers provided high-resolution data on vultures' movements and behavior, enabling the identification of feeding events and the estimation of food deprivation periods (FDPs, measured in days), which is used as a proxy for hunger. RESULTS: Data from 47 vultures, tracked for 339 ± 36 days, reveal high variability in FDPs. While flight speed, flight straightness and the proportion of active flights were invariant in relation to food deprivation, a clear hump-shaped response was found for daily flight distances, maximal displacements and flight elevation. These movement characteristics increased during the first five days of the FDP sequence and decreased during the following five days. These characteristics also differed between short FDPs of up to four days, and the first four days of longer FDP sequences. These results suggest a switch from FIMax to EEMin strategies along the FDP sequence. They also indicate that vultures' response to hunger affected the eventual duration of the FDP. During winter (the vultures' incubation period characterized by unfavorable soaring meteorological conditions), the vultures' FIMax response was less intensive and resulted in longer starvation periods, while, in summer, more intensive FIMax response to hunger resulted in shorter FDPs. CONCLUSIONS: Our results show a flexible, non-monotonic response of free-ranging wild animals to increasing hunger levels, reflecting a trade-off between increasing motivation to find food and the risk of starvation. The proposed trade-off offers a unifying perspective to apparently contradictory or case-specific empirical findings.

ABSTRACT

Este artigo objetivou conhecer evidências psicométricas da Escala de Motivações Externa e Interna para Responder sem Preconceito ([EMEI], Plant & Devine, 1998), considerando dois grupos-alvo: gays e lésbicas. Realizaram-se dois estudos. No Estudo 1 participaram 234 pessoas da população geral de João Pessoa (PB), com média de idade de 26 anos, a maioria do sexo feminino (54,3 por cento) e heterossexual (95 por cento). Eles responderam a versão da EMEI para gays. Análises fatoriais confirmatórias revelaram como mais adequado o modelo bifatorial (AGFI = 0,94, CFI = 0,98 e RMSEA = 0,05). Os Alfas de Cronbach dos fatores foram 0,74 (motivação interna) e 0,76 (motivação externa). No Estudo 2 participaram 202 pessoas da população geral da mesma cidade, com idade média de 25 anos, a maioria do sexo feminino (60,9 por cento) e heterossexual (95 por cento). Eles responderam a versão da EMEI para lésbicas. Corroborando o estudo anterior, uma estrutura bifatorial se mostrou mais adequada (AGFI = 0,90, CFI = 0,95 e RMSEA = 0,08). Os Alfas de Cronbach para os dois fatores foram 0,71 (motivação interna) e 0,84 (motivação externa). Reuniram-se evidências complementares de validade de construto destas versões. Concluindo, os resultados apoiaram a adequação psicométrica (validade fatorial, validade convergente-discriminante e consistência interna) da EMEI, que poderá ser empregada em pesquisas futuras sobre preconceito frente a gays e lésbicas.


The current article aimed to find psychometric evidences in the Internal and External Motivation to Respond without Prejudice Scale (Plant & Devine, 1998) taking into account two target-groups: gays and lesbians. Two studies were carried out. In Study 1 participants were 234 subjects from the general population of João Pessoa-PB, with mean age of 26 years old, most of them female (54.3 percent) and heterosexual (95 percent). They answered the gay version of the Internal and External Motivation to Respond without Prejudice Scale (IEM Scale). Confirmatory factor analyses indicated that the two-factor model (AGFI = .94, CFI = .98, and RMSEA = .05) is the most adequate. Cronbach's Alphas for the factors were .74 (internal motivation) and .76 (external motivation). In Study 2 participants were 202 subjects of general population from the same city, with mean age of 25 years old, most of them female (60.9 percent) and heterosexual (95 percent). They answered the lesbian version IEM Scale. Corroborating the previous study, a two-factor model was more adequate (AGFI = .90, CFI = .95, and RMSEA = .08). Cronbach's Alphas for the two factors were .71 (internal motivation) and .84 (external motivation). Complementary evidences of the construct validity were also presented. In conclusion, the results support the psychometric adequacy (factorial validity, convergent-discriminant validity, and reliability) of the IEM Scale suggesting it can be used in future studies about prejudice toward gays and lesbians.

No Estudo 2 participaram 202 pessoas da população geral da mesma cidade, com idade média de 25 anos, a maioria do sexo feminino (60,9 por cento) e heterossexual (95 por cento). Eles responderam a versão da EMEI para lésbicas. Corroborando o estudo anterior, uma estrutura bifatorial se mostrou mais adequada (AGFI = 0,90, CFI = 0,95 e RMSEA = 0,08). Os Alfas de Cronbach para os dois fatores foram 0,71 (motivação interna) e 0,84 (motivação externa). Reuniram-se evidências complementares de validade de construto destas versões. Concluindo, os resultados apoiaram a adequação psicométrica (validade fatorial, validade convergente-discriminante e consistência interna) da EMEI, que poderá ser empregada em pesquisas futuras sobre preconceito frente a gays e lésbicas.(AU)


The current article aimed to find psychometric evidences in the Internal and External Motivation to Respond without Prejudice Scale (Plant & Devine, 1998) taking into account two target-groups: gays and lesbians. Two studies were carried out. In Study 1 participants were 234 subjects from the general population of João Pessoa-PB, with mean age of 26 years old, most of them female (54.3 percent) and heterosexual (95 percent). They answered the gay version of the Internal and External Motivation to Respond without Prejudice Scale (IEM Scale). Confirmatory factor analyses indicated that the two-factor model (AGFI = .94, CFI = .98, and RMSEA = .05) is the most adequate. Cronbach's Alphas for the factors were .74 (internal motivation) and .76 (external motivation). In Study 2 participants were 202 subjects of general population from the same city, with mean age of 25 years old, most of them female (60.9 percent) and heterosexual (95 percent). They answered the lesbian version IEM Scale. Corroborating the previous study, a two-factor model was more adequate (AGFI = .90, CFI = .95, and RMSEA = .08). Cronbach's Alphas for the two factors were .71 (internal motivation) and .84 (external motivation). Complementary evidences of the construct validity were also presented. In conclusion, the results support the psychometric adequacy (factorial validity, convergent-discriminant validity, and reliability) of the IEM Scale suggesting it can be used in future studies about prejudice toward gays and lesbians.(AU)
